Abstract:

Car as a vehicle has a suspension on the wheels that connect the body with the road surface. The suspension is arranged in such way as to ensure the comfort in driving even on uneven road surfaces or damaged road surfaces. Because of the changes in road surface, it is very important to make adjustments to the suspension. The car suspension is adjusted using Neuro-Fuzzy Adaptive PID Control System so that the performance of the suspension can be improved in ensuring user comfort by reducing vibrations in the car body. Improved performance can be seen in the results of the suspension setting, which can suppress the movement of the car body because of the change in road surface more than 80%.

Abstract:

In this study, Ti-6Al-4V was machined under high pressure cooling conditions. Cutting parameters which were assumed as independent variables are consist of 4 different levels of cutting speed (Vc: 50-70-90-110 m/min), feed rate (f: 0.05-0.1-0.15-0.2 mm/rev) and cutting fluid pressure (P: 6-100-200-300 bar). By using SPSS 20 software, regression equations of surface roughness relative to cutting parameters was obtained as linear, second degree and linear logarithmic. Second degree multiple regression model showed best results of estimation. In the model, 95 percent of the surface roughness alterations can be explained by independent variables. Correlation between experimental data and the model was calculated as 0.975. As a result, second degree regression model proved to be successful in predicting surface roughness. The result of the study confirms the literature. When models are compared the most important parameter that affects surface roughness was observed as the feed rate. The results of the study confirms the literature.

Abstract:

One of the primary goals in endodontics is efficient cleaning and shaping of the root canal while maintaining its original configuration. Numerous studies highlight the advantage of using nickel-titanium instruments and the most important is their high flexibility and the ability to penetrate the curved canals. The aim of this study was to analyze the ultrastructure of the surface of nickel-titanium endodontic files before and after use. Eighty-four instruments were included in this study. The instruments were used one, three and six times for root canal preparation on extracted upper premolars. The analysis was performed based on the number of uses and the size of the instruments. Changes on flat surfaces in the grooves of the instruments, defects of the cutting edges and fractures were evaluated. The surface ultrastructure was analyzed on a scanning electron microscope (SEM). SEM analysis showed irregularities on the surfaces of the new instruments. Surface defects and damage of the cutting edges were present after the first use. After three uses, the damage was more evident in instruments of all sizes. After six uses, all instruments showed damage of the cutting edges, and a significant number of fractures were observed. Irregularities on the working parts are already noticed on the new endodontic instruments and originate from the production process. The first signs of damage appear after the first use. In order to prevent errors in clinical work during root canal preparation, it is recommended that the number of instruments uses should be limited.

Abstract:

In friction stir welding, lesser tool life restricts the usage of non-circular pin in friction stir welding tool eventhough it delivers comparatively better weld joints than circular pin. Process peak temperature during the process affects the shear strength of the flowing material around the tool pin. Maintaining the process peak temperature as low as possible improves the properties in heat affected zone but on the other hand it increases the stress on the tool pin.Especially on the usage of non-circular pin, the pin surface experiences uneven stress distribution and causes premature tool failure. In this paper, optimum thermal environment through proper selection of process parameters and dwell period with respect to the pin geometry are analysed. A comparative analysis is also made to understand the impact of increase in flat surfaces in the pin surface on weld quality in the view of developing a suitable thermal environment that can improve tool life without compromising joint strength. Apart from this, optimum dwell period for the chosen tool pin geometry is analysed based on the empirical softening temperature of the material.

Abstract:

Evidence must be presented neatly and with care to solve forensic cases because the ability to resolve legal cases depends only on the availability of appropriate evidence. Evidence is used to uncover connections between the victim, the place and time of the incident, and the perpetrator in order to resolve the incident. One of the most important types of evidence examined in forensic investigations is textile materials. Because everyone who commits a crime or is a victim of crime is in contact with textile surfaces. Textile products such as clothing, furniture, knife marks on fabric, blood on car upholstery, vehicle upholstery found at the crime scene can be used as evidence to help solve the crime. During forensic examination, fibers can be classified according to certain criteria such as colour, shape, surface texture, thickness, fluorescent properties, and chemical composition. As a result of examining these classifications, the case can be clarified as quickly as possible. Otherwise, finding the perpetrator may become more difficult as time goes on.

Abstract:

A plane is a tool related to woodworking, which is used for smoothening the surface of the wood. Currently, there are many different smoothing planes available in the market. In this study, the evaluation of a self-made hand plane was conducted. One of the variables that can be utilized to investigate smoothing plane’s performance is by analyzing its wood’s surface smoothening capability. In this reserch, the smoothening capability was evaluated by measuring the wood’s surface roughness after the smoothening process. This study was conducted by utilizing three different types of wood namely limestone wood, meranti wood, and kempas wood as well as three different planes that are a mini plane (self-made tool), a commercial plane, and a power planer. The results show that prior to smoothening process, the maximum surface roughness was 16.432 µm for wet limestone wood and the minimum was 7,871 µm for kempas oven wood. After the smoothening process, the surface maximum roughness values are 10,932 µm using hand mini plane, 12,329 µm for kapur basah wood with the commercial plane for kapur basah wood and minimum roughness of 4,982 µm obtained hand mini plane for meranti oven wood and 5,826 µm for meranti oven wood with the commercial plane. It was also observed that the self-made mini plane gave lower values of surface roughness compared to commercial plane. Thus, it could be summarized that the self-made plane (mini hand plane) is capable to be used for the wood surface smoothening and it has better performance compared to the commercial plane.

Abstract:

AbstrakShot peening merupakan metode pengerjaan dingin dengan menumbukkan permukaan logam menggunakan partikel-partikel bulat yang berukuran kecil dan berkecepatan tinggi. Dengan proses shot peening dapat dikurangi inisiasi dan propagasi retak yang menyebabkan terjadinya kegagalan terhadap logam. Tujuan penelitian ini adalah untuk mengetahui pengaruh intensitas dan coverage shot peening terhadap tegangan sisa dan kekerasan pada permukaan Al 7075 T7351. Penelitian dilaksanakan dengan menembakkan permukaan logam dengan intensitas 0,0062 A dan 0,0091 A, serta coverage masing-masing 100% dan 200%, kemudian dilakukan pengujian kekerasan permukaan dan tegangan sisa. Hasil penelitian menunjukkan bahwa shot peening menyebabkan terjadinya perubahan tegangan sisa, yaitu 92,5021 MPa pada keadaan tanpa shot peening menjadi -111,8726 sampai -170,5675 MPa setelah dilakukan dishot peening. Selain itu kekerasan pada permukaan meningkat antara 23,4% sampai dengan 44,7%. Meningkatnya kekerasan menunjukkan bahwa terjadi pengerjaan dingin yang besar pada permukaan logam. Pengaruh pelapisan (coverage) 200% ternyata meningkatkan besarnya tegangan sisa dan kekerasan permukaan walaupun belum melampaui intensitas yang lebih besar. Kata kunci : shot peening, intensitas, coverage, kekerasan permukaan, tegangan sisa AbstractShot peening is a cold working method by striking metal surfaces using small, high-speed and round particles. Shot peening can reduce the initiation and propagation of cracks that cause metal failure. The purpose of this analysis is to determine the effect of shot peening intensity and coverage on residual stress and hardness on the surface of Al 7075 T7351. The research was carried out by firing metal surfaces with intensities of 0.0062 A and 0.0091 A, and coverage of 100% and 200%, respectively, then testing surface hardness and residual stress. The results showed that shot peening caused a residual stress change, which was 92.5021 MPa in the state without shot peening to -111.8726 to -170.5675 MPa after it was shot peening. In addition, surface hardness increased from 23.4% to 44.7%. Increased hardness indicates that there is large cold working on the metal surface. The effect of 200% coverage apparently increases the amount of residual stress and surface hardness even though it has not exceeded the greater intensity. Keywords: shot peening, intensity, coverage, surface hardness, residual stress

Abstract:

Along with the increasing needs of people inMakassar city for the mode of transportation, the number of thegrowth of motor vehicles that operate on the road becomes largerthan the growth of the number of roads built. This has causedsome problems in the transportation sector. In addition tocongestion problems, problems arise from road surface damagedue to increasing traffic loads that must be borne by the roadsurface. To anticipate this, some strategic streets in the city ofMakassar then designed by using a rigid pavement that hasgreater strength in carrying the burden. Another problem thatarises from the growing number of motor vehicles that operateon the road is greater than the growth of the number of roadsbuilt is the higher levels of noise pollution or traffic noise. Noise issourced from the sound of a vehicle engine and the frictionbetween the vehicle tire and the road surface. So that roads withrigid surface pavement surfaces that have a rougher surfacetexture, potentially lead to higher noise levels. This study aims todetermine how much noise levels that occur in roads that userigid pavement in the city of Makassar. The road segments, suchas Jl. Abd. Dg. Sirua, Jl. Batua Raya and Jl. Adhyaksa. The toolused to measure traffic noise is the Sound Level Meter (SLM).The survey was conducted for 1 day for each of the roadsegments reviewed. The data taken are the level data of flatnessof road surface, vehicle speed data and traffic noise level data.Data processing is done by analyzing the relationship between thefactors that affect the noise with the noise level that occurs on theroad with rigid pavement. The results of this study are expectedto provide information about how big the effect of vehicle speedon the noise level that arises on the road with rigid pavement.Keyword--Noise; speed of vehicle; Rigid Pavement

Abstract:

An experimental study in condensation has been conducted to analyse the condensation phenomena. The enhancement heat transfer performance is as always highlighted phenomenon for being investigated. The modified surface is a common method for enhancing the performance of condensation since inducing the droplet on the surface. The droplet leads to increasing heat-transfer area, decreasing thermal resistance, and shorten the condensing cycle. The condensation by using water successfully induces droplets on the surface and enhances the heat transfer. But water and refrigerant have different fluid properties which induce different phenomena whereas refrigerant is widely used in industry. In this case, the condensation is conducted on the modified surface by using a commercial promotor to investigate the phenomena. The investigation results show that the surface tension immensely influences the condensate on the surface. Refrigerant is low surface tension fluid which leads to the difficulty of fluid for inducing droplets and almost no enhancement heat transfer performance since the results almost fitted well to Nusselt bare tube prediction around 2443-3063 W/m2 oC with subcooled temperature 2 up to 5 oC.

Abstract:

Malware salah satu virus yang memiliki banyak cara dalam menginfeksi sebuah data dan dapat memberikan kerusakan yang berbahaya, seperti yang terjadi pada salah satu rumah sakit ternama, dimana malware menyerang seluruh data yang ada sehingga data tidak dapat diakses kembali oleh pihak yang terkait. Malware bukan hanya menyerang data, tetapi dapat merusak sistem operasi yang sedang digunakan karena rentan untuk disusupi, salah satunya adalah sistem operasi windows. Malware sangat sulit di intifikasi dengan file data yang asli jika tidak menggunakan bantuan tools analisis, dengan hal tersebut penelitian akan melakukan analisis dan pengujian terhadap tingkah laku malware, sehingga dapat diketahui pola dan jenis malware dengan 2 metode analisis yaitu metode surface analisis (Pestudio, Strings, Exeinfo dan Virus) dan runtime analisis ( Regshot, CaptureBAT, Noriben Malware Analysis). Analisa yang dilakukan menciptakan lingkungan kerja sebagai tempat uji coba, sehingga tidak menggangu sistem utama yang telah berjalan. Dengan uji coba yang dilakukan, jadi didapatkan bahwa File dengan nama "games.exe” dapat dikatakan malware karena memiliki strings dan dapat menggandakan diri ke folder system32 yang dibuktikan dengan MD5.

The current electrical dish machine machining (EDM) machine in the field of manufacturing has developed along with conventional machines such as Lathes, Milling Machines, and Grinding Machines as the leading technology. EDM is known for its ability to make complex shapes on very hard metals. EDM machines are widely used in the manufacture of dies, cutting tools, and molds that cannot be done with the cutting process. Therefore the level of electrode wear in the EDM process must be as efficient as possible. The research was conducted to determine the exact EDM process parameter setting values. Variable parameters are current, on time, off time. To optimize the response of this study using the Response Surface Methodology (RSM) method. High electrode wear is obtained in testing with parameters used Ton (300 μs), Toff (15 μs) and Current (20 A), and the smallest wear value is obtained in the test with the parameters used Ton (100 μs), Toff (15 μs) and Current (10 A).

Abstract:

This paper analyses the influence of machining strategies and cutting parameters on the milling of aluminium complex geometry parts. In the first experimental phase, parts were machined with a combination of two roughing strategies and three finishing strategies, with recommended machining parameters. The machining time, machining surface roughness, and the surface geometric accuracy were measured. In the second phase, a new sample was machined with corrected cutting parameters using the best strategy adopted from the first phase. The results have shown that the selection of machining strategy and cutting parameters significantly affects the productivity, quality, and accuracy when machining complex geometry parts.

Abstract:

Diakhir tahun 2019 terjadi kejadian yang mengejutkan seluruh penduduk dunia, yaitu menyebarnya virus baru pnemunia corona (COVID-19) dengan sangat cepat ke seluruh dunia. Di beberapa negara yang terdampak COVID-19, seperti China, Inggris, Italia, Spanyol, Prancis, , Malaysia dan Filiphina telah menerapkan status lockdown secara menyeluruh. Studi ini ingin mengembalikan analisa lockdown atau tidak, berdasarkan dasar-dasar teori ekonomi yang dikembangkan, agar analisa yang dilakukan oleh para pengambil kebijakan lebih mendasar dan fundamental. Penelitian ini masih sangat awal, karena wabah baru terjadi di akhir 2019 sehingga metodologi yang dilakukan adalah dengan metode kualitatif berupa literature review. Perdebatan terhadap kebijakan dikotomi antara lockdown atau tidak lockdown sangatlah menyesatkan jika tidak direncanakan secara hati-hati. Kebijakan lockdown ini hanya merupakan kebijakan “antara” dalam mencegah virus COVID-19 lebih meluas penyebarannya.

Abstract:

Groundwater and surface water are important sources of clean water which require an effective management. The use of groundwater and spring as exemplified by Batu City case – as part of Brantas watershed upstream – serves as raw water as well as clean water source for Batu City and Malang City population. Contamination of surface water and groundwater affects clean water supply as indicated by increasing nitrate, TDS, and E. Coli concentration. The study aims to analyze the vulnerability level of groundwater contamination by using spatial multicriteria analysis with DRASTIC index. The DRASTIC index is measured from some parameters such as surface water depth to water table, net recharge, aquifer media, soil media, topography, impact of vadose zone, and hydraulic conductivity to evaluate groundwater vulnerability. The results show that Batu City performs low vulnerability (86.93%) and medium vulnerability (13.07%) levels. The dominant factors affecting the level of vulnerability are groundwater levels, slope, and geological conditions across regions. Even though the DRASTIC modelling cannot specify the contamination levels of the different sources, this method is useful to identifying high-level contaminated land uses, managing water resources, and conserving groundwater sources.

Abstract:

Truk merupakan kendaraan yang berfungsi sebagai pengangkut barang untuk didistribusikan ke suatu tempat. Truk adas juga disusun beberapa komponen salah satu komponennya adalah poros gardan. Poros gardan merupakan poros penggerak yang berfungsi meneruskan gaya penggerak dari differential ke roda. Seringkali terjadi kegagalan pada gardan belakang, hal ini tentunya akan mempengaruhi laju distribusi barang. oleh karena itu penelitian diperlukan ketika kegagalan lebih lanjut terjadi untuk meminimalkan kegagalan di masa depan. Penelitian ini menggunakan dua metode, yaitu fraktografi dan pengujian komposisi. hasil pengujian komposisi didapatkan bahwa material tersebut merupakan baja paduan dengan standar AISI 4140 dan tidak ditemukan masalah. Dari pengamatan fraktografi hingga pengamatan visual, ditemukan bahwa beach mark merupakan karakteristik dari pembebanan berulang. Pada saat diperoleh perbesaran terdapat retak sebelum terjadi beachmark dan sebelum ujung sesar terdapat permukaan yang rata akibat konsentrasi tegangan pada saat komponen poros poros mengalami kegagalan. A truck is a vehicle that functions as a carrier of goods to be distributed to a place. The truck is also arranged fennel several components one of the components is the axle shaft. The axle shaft is the drive shaft that functions to continue the driving force from the differential to the wheel. Often there is a failure on the rear axle, this will certainly affect the rate of distribution of goods. therefore research is needed when further failure occurs to minimize future failures. This study uses two methods, namely fractography and composition testing. the results of the test composition obtained that the material is an alloy steel with AISI 4140 standards and no problems were found. From fractographic observations to visual observations, it is found that the beachmark is a characteristic of repeated loading. When an enlargement is obtained there is a crack before the beachmark occurs and before the end of the fault there is a flat surface due to stress concentration when the axle shaft component fails.

Abstract:

Titanium Grade 2 termasuk jenis bahan yang sering dipergunakan di industri, utamanya pada bahan untuk implan biomedis. Titanium Grade 2 mempunyai sifat perbandingan kekakuan terhadap berat yang baik, tahan terhadap korosi dan memiliki sifat biokompatibel yang baik di dalam tubuh. Namun memiliki konduktifitas panas yang rendah, sehingga perlu memilih perameter pemesinan yang tepat untuk menghasilkan nilai kekasaran permukaan yang baik. Penelitian ini bertujuan untuk mengetahui karakteristik Titanium Grade 2 yaitu kekasaran permukaan hasil pemesinan frais. Desain penelitian menggunakan metode Taguchi L9, dengan 2 faktor dan 3 level. Parameter pemesinan yang digunakan ialah putaran spindel 500; 700; 900 rpm dan kecepatan pemakanan 25; 50; 75 mm/menit. Variabel respon yang diteliti ialah kekasaran permukaan. Proses frais dilakukan menggunakan Mesin CNC Dahlih. Kekasaran permukaan diukur menggunakan Mitutoyo surface roughess tester. Analisis data menggunakan analisis ANOVA. Hasil penelitian menunjukan bahwa ada pengaruh variasi parameter pemesinan terhadap respon kekasaran permukaan. Variabel putaran spindel mempunyai p-value sebesar 0,039 dan variabel gerak makan memiliki p-value sebesar 0,025. Hal ini menunjukkan bahwa kedua variabel bebas tersebut memiliki pengaruh yang signifikan terhadap respon kekasaran permukaan. Kekasaran permukaan terendah dapat dicapai dengan pengaturan putaran spindel sebesar 700 rpm dan kecepatan pemakanan sebesar 25 mm/menit.

Abstract The surface grammar of reports such as ‘I have a pain in my leg’ suggests that pains are objects which are spatially located in parts of the body. We show that the parallel construction is not available in Mandarin. Further, four philosophically important grammatical features of such reports cannot be reproduced. This suggests that arguments and puzzles surrounding such reports may be tracking artefacts of English, rather than philosophically significant features of the world.

Abstract:

Concrete-faced rockfill dam (CFRD) has a similar weakness to other types of dams, namely deformation. Surface movement monuments can be used to monitor the deformation that occurs on the surface of the dam. Analysis of the monument's measurement data can show settlement and displacement trends that are closely related to the deformation of the dam itself. In this research, the monuments measurement data are compared to acceptance criteria from ICOLD, Sowers, Clements, Fell, and the Ministry of Public Works and Housing as outlined in the Guidelines for The Design and Construction of Concrete Membrane Stone Backfill Dams. This study aims to analyze data from surface movement monuments to determine the settlement and displacement of the dam based on the criteria of deformation. According to the obtained result, the first segment of surface monuments settlement values ranged from 0.028 to 0.165%, which meet the majority of the criteria. In addition, displacement values at the first segment of surface movement monuments were within 0.022 – 0.071%, which meets the ICOLD and Clements criteria. Meanwhile, for the second to fourth segments of surface movement monuments, settlement values of 0.007 – 0.102% were obtained, which still conform to the ICOLD and Fell criteria.

Abstract:

Tekstur permukaan jalan umumnya terdiri dari aspal dan beton. Kekasaran tekstur permukaan jalan dapat disebabkan oleh struktur perkerasan dan beban kendaraan. Kekasaran tekstur permukaan jalan, bebandan kecepatan kendaraan akan mempengaruhi koefisien gesek. Untuk mengetahui nilai koefisien gesek dilakukan penelitian dengan melakukan variasi beban mobil (Daihatsu Xenia, Toyota Avanza, Toyota Innova dan Toyota Yaris) terhadap kontak permukaan jalan (aspal dan beton) dan kecepatan kendaraan. Hasil penelitian menunjukkan bahwa massa, lebar kontak tapak ban terhadap permukaan jalan dan kecepatan sangat mempengaruhi nilai koefisien gesek kinetis. Koefisien gesek kinetis yang terbesar untuk ketiga kontak permukaan jalan (aspal lama IRI 10,1, Aspal baru IRI 6,4 dan beton IRI 6,7) dengan menggunakan mobil Daihatsu Xenia terjadi pada kondisi jalan beton yaitu 0,495 pada kecepatan 35 Km/Jam. Koefisien kinetis jalan beton > 52 % dibandingkan jalan aspal pada parameter IRI yang sama (6-8).Koefisien gesek kinetis > 0,33 diperoleh di jalan beton pada kecepatan 30 – 40 Km/Jam The texture of road surface generally consists of asphalt and concrete. The roughness of the road surface texture could be caused by the structure of the pavement and the load of the vehicles. Roughness of road surface texture, load and speed of vehicles would affect to the coefficient of friction. This research was carried out to find out the value of the coefficient of friction by using various load of cars (Daihatsu Xenia, Toyota Avanza, Toyota Innova and Toyota Yaris) on road surface contact (asphalt and concrete) and vehicle speed. The result showed the mass, the width of the tire tread contact to the road surface, and speed very influenced the coefficient value of kinetic friction. The biggest kinetic friction coefficient for all three road surface contacts (IRI 10.1 old asphalt, IRI 6.4 and IRI 6.7) using the Daihatsu Xenia was on the concrete road condition i.e. 0.495 on a speed of 35 km/hour. The concrete road kinetic coefficient was >52% compared to the asphalt road in the same IRI parameter (6-8). The kinetic friction coefficient >0.33 was obtained on the concrete road on a speed of 30 - 40 km/hour.
