This study aims to determine the identity that emerges through language in Indonesian language major in tertiary engineering concentration. The research was conducted in the Department of Marine Engineering, Sepuluh November Institute of Technology Surabaya. The method used is descriptive qualitative with Van Dijk's critical discourse analysis. Van Dijk's three models are macrostructure, social cognition, and microstructure. The results of the study show that identity does not only emerge from a person's psychological background but is also seen from the language used. most students try to use mimicry in using language, that is, students outside Surabaya try to use Suroboyoan as the language of instruction in discussions in the Indonesian class as an effort to bring out their identity as suroboyo architects, no longer their origin areas to be socially acceptable. Other findings, Indonesian language classes bring up the identity associated with the understanding adopted by students.

The MIPA Tower office building, an eleven-storey building, which is located in the area of Institut Teknologi Sepuluh Nopember Surabaya, is under construction. The building will be utilized for offices, classrooms, and laboratories. In the operation of the building, domestic and laboratory wastewater will be produced. This wastewater contains compounds that can pollute the environment. A design of domestic and laboratory wastewater treatment system is conducted. The system comprises of a neutralization tank, a grease trap, an equalization tank, an anaerobic filter, and an activated carbon and silica sand filter. The steps of the design are (i) collecting primary data and secondary data, (ii) calculating the engineering design, (iii) drawing the Detailed Engineering Design (DED), and (iv) calculating the bill of quantity and budget. The conclusion of this design is that the treatment plant will treat a mixture of domestic and laboratory wastewater. The dimension of each unit is as follows: (i) the neutralization tank (Ø = 0.65 m, H = 0.43 m), (ii) the grease trap (4 m x 2 m x 1 m), (iii) the equalization tank (10.5 m x 5.5 m x 2.5 m), (iv) the septic tank (4.5 m x 4 m x 2.5 m), (v) the six-compartment anaerobic filter (2.25 m x 4 m x 2.5 m), and (vi) the filter with activated carbon (H = 50 cm), silica sand (H = 150 cm), and gravel (H = 10 cm), with the diameter of the tank is 1.5 m.

The area of the campus of Institut Teknologi Sepuluh Nopember (ITS) and its housing complex are usually inundated during heavy rain. It is because the slope of the land in the campus generally flat. Moreover, it is because some of the drainage channels contain sediment that reduce the optimum capacity of the channels. Hence, an evaluation of the drainage system of ITS needs to be conducted. The steps of doing this evaluation are (i) identification of the existing problems, (ii) collection of primary and secondary data, (iii) literature review, (iv) calculation of capacity of the existing channels, (v) calculation of runoff, and (vi) analysis of the existing retention ponds. The primary data includes flow direction, the slope of channels, dimension of channels, and thickness of sediment in the channels. The secondary data comprises of rainfall intensity, Master Plan of ITS, and land-use. The calculation includes engineering design, bill of quantity (BOQ), and budget. A standard operation procedure for maintenance of drainage system to make the channels optimum is also suggested. From the analysis, it is shown that the maximum daily rainfalls are 136.09 mm/day for 5 year-rainfall return period and 159.19 mm/day for 10 year-rainfall return period. The cause of inundation in ITS is there are some channels which are not connected to each other. As a result, the drainage water cannot flow easily to receiving water body (river). Another cause of inundation is the slope of some channels that does not properly made. The inundation of some roads is because there are no street inlets such that the water could not flow to the side channels. It can be concluded that (i) it needs some addition of secondary channels and box culvert in some areas, (ii) the slope of some channels need to be rearranged, (iii) 288 street inlets must be constructed along the planning area.

PENETAPAN HARGA BERBASIS PENERIMAAN KONSUMENDI DUAL-CHANNEL SUPPLY CHAINERWIN WIDODOJurusan Teknik Industri, Institut Teknologi Sepuluh Nopember (ITS) SurabayaKampus ITS, Sukolilo, Surabaya 60111Surel: erwin@ie.its.ac.idABSTRAKDual-Channel Supply Chain (DCSC) adalah sebuah struktur gabungan yang secara simultanmemanfaatkan online dan offline channel untuk mendistribusikan sebuah produk. Struktur ini menjanjikanperluasan jangkauan pasar yang berujung pada peningkatan pendapatan. Meskipun demikian, selainmenawarkan potensi, DCSC juga membawa beberapa problem. Salah satu problem yang dominan adalahpenetapan harga harga antar channel. Pada prakteknya, para pelaku DCSC seringkali secara intuitifmenetapkan harga online dan offline-nya. Belum ada sebuah mekanisme pengukuran yang representatifuntuk problem yang sebenarnya sangat penting ini. Paper ini mencoba menjawab tantangan tersebutdengan mengusulkan sebuah mekanisme estimasi pengukuran secara kuantitatif tentang penerimaanpelanggan terhadap online channel relatif terhadap offline channel. Pendekatan yang diusulkan adalahpemanfaatan model matematis tentang hubungan interplay antar harga online dan offline. Parameterpenting yang menjadi perhatian utama adalah sebuah rasio penerimaan pelanggan kepada online channelrelatif terhadap offline channel. Parameter ini diukur dari 3 kelompok produk yang dijual dalam strukturDCSC yang ada di Indonesia guna menunjukkan perbedaan karakteristik dari masing-masing kelompokproduk tersebut. Hasil percobaan numerik yang dilakukan menunjukkan bahwa pemanfaatan usulanmekanisme penetapan harga ini dapat meningkatkan performansi finansial DCSC amatan.Kata kunci: dual-channel supply chain, penetapan harga, online channel, offline channelABSTRACTDual-Channel Supply Chain (DCSC) is a mixed structure which simultaneously utilizes both offline andonline channel to distribute one particular product or service. This structure provides market reach extensionin which eventually leads to revenue increase. Whatsoever, aside of this advantage, DCSC also brings somechallenging problems. One prominent problem is of about between-channel pricing-problem. In its practice,DCSC actors often apply intuitive offline and online pricing without further analytical evaluation. Yet there isno representative mechanism to address this critical problem. This paper attempts to resolute this challengeby proposing a qualitative estimation mechanism on customer acceptance on online channel relative tooffline one. This proposed approach is about to utilize an interplay relationship between offline and onlineprices. The main parameter to consider is a ratio of customer acceptance parameters. These parameters areelicited from 3 groups of products which are sold under DCSC structure in Indonesian cases to exhibit thedifferent properties in each product group. Numerical experiment result shows that the utilization of thispricing mechanism may increase the financial performance of DCSC under observation.Key words: dual-channel supply chain, pricing, online channel, offline channel
