Testo completoAbstract (sommario):
Kapok fiber (Ceiba pentandra) belongs to a group of natural fibers that are mainly composed of cellulose, lignin, pectin, and small traces of inorganic compounds. These fibers are lightweight with hollow tubular structure that is easy to process and abundant in nature. Currently, kapok fibers are used in industry as filling material for beddings, upholstery, soft toys, and nonwoven materials. However, kapok fiber has also a potential application in the adsorptive removal of heavy metal ions and dyes from aqueous systems. This study aims to provide a comprehensive review about the recent developments on kapok fiber composites including its chemical properties, wettability, and surface morphology. Effective and innovative kapok fiber composites are analyzed with the help of characterization tools such as scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and Brunauer-Emmett-Teller analysis. Different pre-treatment methods such as alkali and acid pre-treatment, oxidation pre-treatment, and Fenton reaction are discussed. These techniques are applied to enhance the hydrophilicity and to generate rougher fiber surfaces. Moreover, surface modification and synthesis of kapok fiber-based composites and its environmental applications are examined. There are various methods in the fabrication of kapok fiber composites that include chemical modification and polymerization. These procedures allow the kapok fiber composites to have higher adsorption capacities for selective heavy metal and dye removal.

The use of indigo carmine dye in the textile industry is a source of pollution for the environment. The presence of dye pollutants in the environment can threaten the health of living creatures and the sustainability of the ecosystem. This research uses kapok husk biosorbent modified with snail meat. Previously, research on adsorption was carried out on metals and cationic dyes from kapok husk, then in this research adsorption was carried out using the batch method to adsorb anionic dyes. The biosorbent modification process using snail meat aims to add active sites in the form of functional groups to the biosorbent to optimize the dye adsorption capacity. The contact objective of this research is to determine the heating time and temperature conditions for optimal adsorption of indigo carmine using the batch method. The research results showed that the adsorption capacity was at optimum conditions for the adsorption of indigo carmine at a contact time of 60 minutes and a temperature of 25°C.

There is a need to address the gap between the theoretical benefits and cost-efficient production of supercapacitors in the market in order to sway the preference of the industry from the current perishable energy sources and storage. More extensive exploration of sustainable fabrication methods and materials used for renewable energy storage are just some of the factors that would decrease this gap. A binder-free supercapacitor electrode made of NiCo2O4 and carbonized kapok fiber paper (CKFP) was successfully fabricated by hydrothermal process at relatively low temperatures. NiCo2O4 urchin-like structures were deposited on the surface of carbon fiber paper (CFP) and CKFP. XRD analysis confirmed the successful conversion of kapok fiber paper to CKFP after pyrolysis, as well as the growth of pure spinel NiCo2O4 nanostructures on CFP and CKFP. The cyclic voltammetry curves showed that the CFP-NiCo2O4 prepared at 140 °C had the highest specific capacitance of 143.51 Fg-1 at 2 mVs-1. The CKFP-NiCo2O4 synthesized at the same temperature yielded slightly higher specific capacitance of 146.29 Fg-1 at 2 mVs-1, and 508 Fg-1 at 0.5 Ag-1.

Dilatar belakangi dari perkembangan teknologi yang semakin maju di dunia industri yang dulunya menggunakan tangan manusia sekarang tergantikan oleh mesin. Salah satu contoh adalah pemecah dan pemisah kulit kapuk randu yang dulunya masih menggunakan tangan manusia untuk memecah dan memisahkan antara kapuk, kulit, dan biji buah kapuk dalam pengolahannya menjdi kapuk bersih. Hasil dari pengolahan yang menggunakan tangan manusia kurang maksimal dan membutuhkan waktu yang lebih lama. Oleh karena itu telah dibuat mesin pemecah dan pemisah kulit kapuk randu dengan kapasitas 30 kg/jam. Dalam pembuatan mesin ini memerlukan beberapa langkah pengerjaan, yang meliputi persiapan alat dan bahan, mempelajari gambar kerja, pembuatan rangka mesin, pembuatan mata pisau pemecah, pembuatan mata pisau pemisah, pembuatan ruang pemecah, pembuatan ruang pemisah pembuatan hooper input dan output, proses finising dan proses perakitan mesin. Selanjutnya mesin siap diuji coba. Dari proses pembuatan tersebut dihasilkan mesin pemecah kulit kapuk randu dengan kapasitas 30 kg/jam. Dengan putaran mesin 1000 rpm, mesin ini memisahkan antara kulit, kapuk, dan biji kapuk yang nantinya akan dihasilkan kapuk bersih yang siap digunakan.

Kampung Apung is a slum located in Kapuk, West Jakarta. This place was formerly a Chinese and Malay ethnic cemetery known as Tanah Bengkok. Due to urgent housing needs in 1960, The locals built settlements at the edges of the cemetery, forming a settlement called Kapuk Teko.mKapuk Teko filled with rice fields and greenery. In 1979, excessive land reclamation was carried out due to the establishment of warehouses and industrial facilities, resulting in a reduction in land elevation. The continuous flood occurred due to the low lying terrain, leading wastewater from the slum and industries to fill the lower land permanently, and afterwards the slum is known as Kampung Apung. The floods faced a various problems, such as disrupted food chain ecosystem, physical degradation, and the residents’ quality of life. Algaes and water hyscinths began to appear on the wastewater surface as the result.Nevertheless, the “disaster” for the locals can be utilized as a resource for Kampung Apung. The methods used are descriptive, interviews, and direct observation. The program presented is a support community program with the aim of balancing the ecosystem and increasing the quality of life, and addressing physical degradation in Kampung Apung. Keywords: Ecosystem; Physical degradation; Slums; Wastewater Abstrak Kampung Apung merupakan kampung kota yang berlokasi di Kapuk, Jakarta Barat. Wilayah kampung ini dulunya merupakan area pemakaman etnis Cina dan Melayu yang dikenal dengan sebutan Tanah Bengkok. Dikarenakan kebutuhan mendesak akan tempat tinggal, pada tahun 1960, penduduk setempat membangun pemukiman di sekitar tepi pemakaman, yang secara perlahan membentuk pemukiman yang dinamakan Kapuk Teko. Kapuk Teko mempunyai ciri khas kampung yang kaya akan persawahan dan penghijauan. Pada tahun 1979, dilakukan pengurukan tanah secara berlebihan disekeliling pemukiman untuk kebutuhan pembangunan pergudangan dan industri. Pengurukan tersebut menciptakan cekungan pada lahan Kapuk Teko. Karena terjadinya banjir terus menerus dan pembuangan limbah air dari rumah tinggal dan industri, mengakibatkan tergenangnya air secara permanen, membuat pemukiman tersebut menjadi dikenal dengan Kampung Apung. Genangan permanen tersebut menyebabkan ketidakseimbangan dalam ekosistem, memicu degradasi fisik rumah tinggal, dan menurunkan kualitas hidup warga. Alga dan eceng gondok mulai bermunculan di permukaan air sebagai dampak genangan air limbah. Meskipun demikian, “bencana” bagi warga sekitar ternyata dapat dimanfaatkan bagi sumber daya Kampung Apung. Metode analisis yang digunakan adalah metode deskriptif, wawancara, dan observasi secara langsung. Program yang dihadirkan merupakan program pendamping warga yang dibuat dengan harapan agar dapat membantu mengembalikan keseimbangan ekosistem, meningkatkan kualitas hidup warga, serta degradasi fisik di Kampung Apung.

Bonorowo Wetlands 6: 1-11. Mangrove ecosystem is a natural resource that has many ecological benefits in the coastal ecosystems, such as become the habitat and food source for terrestrial and marine biota. One of the Indonesian territory which has fairly large mangrove forest area is in the north of DKI Jakarta Province. That is Angke Kapuk coastal which has 327.70 hectares green belt area and scattered in several regions (BKSDA Jakarta, 2003). Mangrove areas in Angke Kapuk play some important roles in the ecosystem, such as became a preservation habitat for the number of species, especially macrozoobenthos. The environmental degradation along regional development, such as tourism, fisheries activity, and industry cause coastal resources which are mangrove areas to become vulnerable. The purpose of this study was to analyze the ecological functions of mangroves as the habitat of macrozoobenthos in Angke Kapuk coastal region, to determine the extent of damage mangrove state and its sustainable management recommendation of mangrove ecosystems in the Angke Kapuk coastal region. This study was conducted in June 2013 and March 2014 at six different stations based on the representation of the condition of the study site. The data collection consists of macrozoobenthos data collection and measurement of water quality parameters, including turbidity, DO, COD, BOD, salinity, pH, nitrate (NO3-N), nitrite (NO2-N), ortho phosphate (PO4-P), and solids suspended (TSS). The results showed that as the macrozoobenthos habitat, ecological functions of coastal mangrove areas in Angke Kapuk was degraded. The state of mangroves ecology in coastal Angke Kapuk was in damage category based on standard mangrove destruction criteria of Minister of Environment’s Decree Number 201 of 2004. The mangrove density was less than 1000 trees/Ha, and its coverage area was less than 50%, so that rehabilitation effort involving the community and manager sectors for the mangrove area sustainable is necessary. Habitat improvement can be applied through cleaning trash in mangrove areas, especially in group A stations that be the most degraded condition and the largest receiving environmental pressures, as well as the group B stations which potentially fall on ecological function degradation due to high development pressures. To plant mangrove vegetation on the site that is ready to be planted also be another way to improve the habitat.

Kadar besi (Fe) dan total suspensi solid (TSS) dalam air dapat diturunkan dengan menggunakan karbon aktif sebagai media adsorben dan juga nilai pH larutan dapat dinetralkan. Karbon aktif dapat diperoleh dari arang, diantaranya adalah arang sekam padi dan arang kulit pisang kepok. Tujuan penelitian mengetahui bagaimana kualitas karbon aktif sekam padi dan kulit pisang kapok dengan variasi berat yang berbeda, mengetahui pengaruh keefektivitasan karbon aktif dari sekam padi dan kulit pisang kepok, mengetahui penurunan kadar besi (Fe), TSS, dan penetralan nilai pH setelah dilakukan penyerapan dengan karbon aktif sekam padi dan kulit pisang kepok. Tinggi nya konsentrasi logam besi (Fe), TSS dan pH larutan asam, di sepanjang aliran sungai Muara Lebung di Kecamatan Babat Supat kabupaten Musi Banyuasin diakibatkan dari pembuangan air limbah limbah rumah tangga dan industri yang ada di Musi banyuasin. Masyarakat yang berada di sekitar sungai Muara Lebung menggunakan air sungai untuk keperluan mandi dan mencuci. Maka diperlukan suatu cara untuk mengurangi pencemaran pada air sungai Muara Lebung  dengan menggunakan dua macam adsorben. Penelitian ini dilakukan dengan beberapa tahap persiapan sampel, karbonisasi, aktivasi, dan penyerapan kadar air sungai dengan karbon aktif. Berdasarkan hasil penelitian karbon aktif sekam padi dan kulit pisang kepok dengan aktivator H3PO4 pada konsentrasi 0,1N 20% di dapatkan karbon aktif pisang kapok dengan massa 60 gr adalah yang terbaik dari nilai awal TSS 1.370 mg/L mengalami penurunan menjadi 0.29 mg/L, kadar besi (Fe) 0,450 mg/L menjadi 0,00 mg/L, sedangkan nilai pH berubah netral dari 6,4 menjadi 7,6. Kesimpulan yang didapat bahwa karbon aktif kulit pisang kepok lebih baik dari pada karbon aktif sekam padi untuk mendegradasi kadar TSS, kadar besi (Fe) dan meningkatnya nilai pH.

Located in rice fields, Kampung Apung was the same as other villages in that it was on the ground and not floating. However, due to changes in topography, time and urban needs, there has been considerable development into an industrial and warehousing area in the surroundings of the Apung village so that the village becomes hollow and sinks. Changes in the area into industry and warehousing have resulted in the area experiencing a shortage of infiltration areas. The sinking of the village interrupts the daily activities of the residents, disrupts the economy and social life of the residents. Local interventions are presented through Urban Acupuncture using everyday methods and typology. The choice of this method is expected to cure the issue of degradation that occurs in the Kampung Apung. The program presented is in the form of structuring Floating Villages into vertical villages and making creative economic activities in villages with an agricultural base that is equipped with dirty water treatment. It is hoped that the presence of this additional program can increase the economy of the residents of the Kampung Apung so that it can have a positive impact on the Apung village. Keywords: Economic space; agriculture; natural water treatment plant Abstrak Berada pada lahan persawahan di Kapuk, Jakarta Barat, Kampung Apung awalnya sama seperti kampung lainnya yang berada di atas tanah dan tidak terapung. Tetapi karena perubahan topografi, zaman dan, kebutuhan kota, terjadi pembangunan yang cukup besar menjadi kawasan industri dan pergudangan pada lingkungan sekitar kampung Apung sehingga kampung menjadi cekungan dan tenggelam. Perubahan fungsi kawasan menjadi perindustrian dan pergudangan mengakibatkan kawasan mengalami kekurangan area resapan. Tenggelamnya kampung mengganggu aktivitas keseharian warga, perekonomian, dan sosial warga. Intervensi lokal dihadirkan melalui Urban Acupuncture dengan menggunakan metode keseharian dan tipologi. Pemilihan metode ini diharapkan dapat menyembuhkan isu degradasi yang terjadi pada kampung Apung. Program yang dihadirkan berupa penataan Kampung Apung menjadi kampung vertikal dan pembuatan kegiatan ekonomi kreatif pada kampung dengan basis agrikultur yang dilengkapi dengan pengolahan air kotor. Diharapkan dengan hadirnya program tambahan ini dapat menaikkan perekonomian warga kampung Apung sehingga dapat memberi dampak positif bagi kampung Apung.

The purpose of this study was to determine the effect of the marketing mix (7P) on the decision to visit tourists at the Angke Kapuk Mangrove Nature Park. The research method used is quantitative. Determination of the sample using the techniquenon-probability sampling withpurposive sampling method with the number taken is 100 respondents. This study uses multiple linear regression analysis. Based on the results of the t test it is known that partially variableproduct (X1),place (X4), people (X5),process (X6) has a positive and significant effect on the decision to visit (Y), then for variablesprice (X2),promotion (X3),physical evidence (X7) has no positive and insignificant effect on the decision to visit (Y). In the F test, it was obtained that the marketing mix variable (7P) had a simultaneous effect on visiting decisions. Based on the R test2 obtained a value of 0.716. This states that as much as 71.6% of Tourist Visit Decisions are influenced by variables from the Marketing Mix (7P), while the remaining 28.4% are influenced by other variables outside the X variable.Variable conclusionproduct (X1),place (X4), people (X5),process (X6) partially has a positive and significant effect on the decision to visit (Y), while for variables price (X2), promotion (X3), physical evidence (X7) partially has no positive and insignificant effect on the decision to visit (Y).

North Jakarta has potential for maritime tourism and ports because of its place on the coastal area. Like Kamal Muara Fishing Village in Penjaringan Subdistrict, North Jakarta is a slum area and densely populated. To change the impression that slum area, Kamal Muara changes the village’s physicality of painting the village into the colors. This village is starting point for crossing into the Pulau Seribu and is famous for markets and fish auctions. Because of this fish market, the conditions around the port are smelly and dirty. Tourists who want to visit become reluctant to come because of these conditions and often get lost to the Angke Pier. Poor access conditions and frequent traffic jams, because the Kapuk Kamal road has a small right of way 9 meters and is located in an industrial environment. The purpose of this fisherman village management plan is to propose a planning for a fishing village as a tourism village that can be sustainable in accordance with the tourism component and provide a list of activities that can improve the quality of life, economy and environment as a tourist village. The method used is descriptive, benchmarking and perception. Therefore, the planning of Kamal Muara fishing village planning is needed for community participation, because sustainable tourism is not only a physical damage to the environment, but also includes social and cultural as well as economic development, so that the quality of life and income of the community can increase. It takes the government and other institutions to help build a tourist village. Formation of community organizations in creating human resources for the development and management of tourist villages. Keywords: fishing village; Kamal Muara, participation; sustainable tourism AbstrakJakarta Utara memiliki potensi wisata bahari dan pelabuhan karena letaknya yang berada di pesisir. Seperti Kampung Nelayan Kamal Muara yang berada di Kecamatan Penjaringan, Jakarta Utara, merupakan perkampungan kumuh dan padat penduduk, untuk menghilangkan kesan kumuh kampung nelayan merubah fisik kampung dengan mengecat kampung menjadi warna-warni. Kampung ini merupakan titik start penyebrangan ke Pulau Seribu dan terkenal dengan pasar serta pelelangan ikannya. Karena pasar ikan inilah kondisi sekitar pelabuhan menjadi bau dan kotor. Wisataan yang ingin berkunjung menjadi segan untuk datang karena kondisi tersebut dan sering tersesat ke Dermaga Angke. Kondisi akses yang kurang baik dan sering terjadi kepadatan lalu lintas, karena jalan Kapuk Kamal memiliki ROW yang kecil yaitu 9 meter dan berada dilingkungan industri. Tujuan rencana penataan kampung nelayan ini untuk memberikan usulan perencanaan kampung nelayan sebagai kampung wisata yang dapat berkelanjutan yang sesuai dengan komponen pariwisata dan memberikan usulan kegiatan yang dapat meningkatkan kualitas hidup, perekonomian serta lingkungan sebagai kampung wisata. Metode yang digunakan secara deskriptif, benchmarking dan persepsi. Hasil penelitian menunjukan bahwa Kampung Nelayan Kamal Muara memiliki potensi wisata yang dapat dikembangkan dengan menggunakan konsep pariwisata yang berkelanjutan dan wisata berbasis community based development. Oleh karena itu, rencana usulan penataan Kampung Nelayan Kamal Muara dibutuhkan partisipasi masyaraka, karena pariwisata berkelanjutan tidak hanya menyangkut fisik lingkungan, tetapi juga menyertakan sosial dan budaya serta pembangunan perekonomian, sehingga kualitas hidup dan pendapatan masyarakat dapat meningka. Dibutuhkan pemerintah dan lembaga lainnya dapat membantu pembangunan kampung wisata.

Abstract This study investigates the mechanical properties of hybrid composites composed of web kapok fibers and fiberglass reinforced with epoxy for potential application in the marine industry. The web kapok fibers were carefully processed using a carding technique to ensure better alignment and consistency. Various composite configurations were produced, and extensive mechanical testing was conducted, including flexural, tensile, and impact tests. The results revealed that the presence of two web kapok fiber layers within the composite significantly increased flexural strength and flexural modulus compared to pure fiberglass laminates. However, a single layer of web kapok fabrics exhibited the highest tensile strength, although it decreased with additional layers. The impact strength of these hybrid composites also showed promising results, especially when compared to raw fiberglass composites. Moreover, these composites exhibited improved resistance to water absorption and corrosion, making them potentially suitable for marine applications. This research highlights the potential of web kapok/fiberglass hybrid composites as an eco-friendly alternative for marine engineering, with implications for reduced environmental impact and sustainable technology in the industry.

From the past until now, urban kampong is often ignored and neglected from the landscape of a city. When viewed physically, the urban kampong is generally known as a settlement that grows in an urban area without any infrastructure planning and urban economic network. Even so, the urban kampong is a residential area in urban areas. The identity of the urban kampong is determined mainly by the activities carried out by its residents. Similar conditions were found in Kampung Apung, Jakarta. A long history, from the construction of warehousing and industry to the elevation of the road as high as 2m, has resulted in the surface of Kampung Apung being lower than Jalan Kapuk Raya. This is supported by the record of land subsidence in Kapuk Village which can reach 3m in 2025. This condition causes the floating village to be inundated with dirty water as high as 1.5 m – 2 m throughout the year. Forcing residents to live in high density, but on the one hand, it is difficult to meet their daily needs to the lack of facilities and public spaces for the community. The Public Space is an example of how the water space, which is the passive space of Kampung Apung can be used for children's play and study space. The Public Space explores the science of simple construction on water through a combination of architectural design and local craftsmanship. Built-in a collaborative and participatory way with many parties so they can learn together and foster a sense of ownership of the results being fought for. Through Participatory Action Research methods, it is hoped that the results of a Public Space Development project can impact the people of Kampung Apung, especially as a place for children to play now and in the future. ABSTRAK: Dari dulu hingga kini, kampung kota sering kali tidak dianggap dan terabaikan dari lanskap sebuah kota. Jika dilihat secara fisik, kampung kota secara umum diketahui sebagai suatu permukiman yang tumbuh di kawasan urban tanpa adanya perencanaan infrastruktur dan jaringan ekonomi kota. Meskipun begitu, Kampung kota yang merupakan kawasan permukiman di perkotaan, identitas yang dimiliki kampung kota sangat ditentukan oleh aktivitas yang dilakukan penghuninya. Kondisi serupa ditemukan di Kampung Apung Jakarta. Sejarah yang panjang mulai dari pembangunan pergudangan dan industri sampai dengan peninggian jalan setinggi 2m, mengakibatkan permukaan Kampung Apung menjadi lebih rendah daripada Jalan Kapuk Raya. Hal ini didukung dengan rekor penurunan muka tanah di Kelurahan Kapuk yang dapat mencapai 3m pada tahun 2025. Kondisi tersebut mengakibatkan Kampung Apung tergenang air kotor setinggi 1,5 m – 2 m sepanjang tahunnya. Memaksa warga untuk tinggal dengan kepadatan tinggi namun di satu sisi kesulitan untuk memenuhi kebutuhan sehari–hari, hingga minimnya fasilitas dan ruang ruang publik masyarakatnya. Ruang Publik Darat menjadi contoh bagaimana ruang air yang menjadi ruang pasif Kampung Apung dapat dimanfaatkan untuk ruang bermain dan belajar anak-anak. Ruang Publik Darat mengeksplorasi ilmu konstruksi sederhana di atas air melalui gabungan desain arsitektur dan ketukangan lokal warga setempat. Dibangun dengan cara yang kolaboratif dan partisipatif dengan banyak pihak sehingga dapat secara bersama-sama belajar serta menumbukan rasa kepemilikan akan hasil yang diperjuangkan. Melalui metode Participatory Action Research diharapkan hasil dari sebuah proyek Pembangunan Ruang Publik Darat dapat memberikan dampak bagi masyarakat Kampung Apung, terutama sebagai tempat bermain anak-anak di masa sekarang dan yang akan datang.

This paper tries to analyze of prognosis of the Integrated Tourism Area Planning of Kapuknnaga Beach (KWTPK) Tangerang Regency West Java. The two method applied to compose the prognosis are extrapolation and indication. The extrapolation is based on the local area infomation data of contemporary knowledge in the past and presence, while the indication method utilizes the whole interrelation activities programmed with the possible consequences. Land function transformation effects of KWTPK will cause environmental destroy as annual flsh flood, salt water intrusion and polution of urban’s industry sewage. As further effect there is a raising of turbidity and nitrition degree of sedimentation which make coral-ridge degradation toward annihilation. The coral-ridge annihilation will cause the sea waves power collide with the seashore area directly which threatens KWTPK.

Testo completoAbstract (sommario):
Pada dasarnya industri pengrajin usuk bambu yang berada di pinggiran kabupaten Malang yaitu tepatnya di dusun krewe Desa Gunungrejo Kecamatan Singosari Kabupaten Malang. Sebelum kemerdekaan yang silam sudah melakukan usaha usuk bambu ini, hanya dengan berbekal peralatan palu, linggis, pahat, kapak, dan sabit. Dengan bahan dasar bambu dapat di hasilkan usuk dan gedek. Pada dasarnya permasalahan yang dihadapai mitra dua aspek utama yaitu permasalahan produksi dan permasalahan manajemen adalah masalah proses penghalusan usuk bambu yang kurang bermutu dan membutukan waktu lama, masih menggunakan sistem pemasaran konvensional, masalah kendali mutu produk, belum dilakukan pembukuan yang tertib, arus kas masih tidak jelas, tidak ada neraca bulanan, dan sejenisnya, Target luaran dan solusi dari program ini adalah menghasilkan produk usuk bambu dengan kualitas yang lebih baik sehingga pengrajin lebih berkembang dan memiliki segmentasi pasar yang lebih luas, menghasilkan alat penghalus bambu yang dapat digunakan untuk menghaluskan bambu utuh menjadi usuk yang halus sehingga dalam pembuatan usuk bambu tidak menjadi kendala dalam proses produksi, menghasilkan sistem pengelolaan keuangan dalam pengrajin sehingga semua transaksi dapat tercatat dan ternalisa dengan baik.

Testo completoAbstract (sommario):
In customer support contact centers, every service interaction involves a messaging dialogue between a customer and an agent; together, they exchange information, solve problems, and collectively co-produce the service. Because the service progression is shaped by the history of conversation thus far, we propose a bivariate marked Hawkes process cluster model of the customer-agent interaction. To evaluate our stochastic model of service, we apply it to an industry contact center data set containing nearly 5 million messages. Through both a novel residual analysis comparison and several Monte Carlo goodness-of-fit tests, we show that the Hawkes cluster model indeed captures dynamics at the heart of the service and surpasses classic models that do not incorporate the service history. Furthermore, in an entirely data-driven simulation, we demonstrate how this history-dependent model can be leveraged operationally to inform a prediction-based routing policy. We show that widely used and well-studied customer routing policies can be outperformed with simple modifications according to the Hawkes model. Through analysis of a stylized model proposed in the contact center literature, we prove that service heterogeneity can cause this underperformance and, moreover, that such heterogeneity will occur if service closures are not carefully managed.
