<![CDATA[The workbenches that are often found today were originally designed with universal needs in mind. In general, workbench designs that are often encountered in design studios do not consider the work area and storage area. One of the problems that arise from this design is the limited access to storage of design work and design work using manuals and computers. This study discusses the design of a work desk that carries a multifunctional concept. The design of the workspace that carries this multifunctional concept is important to do in order to provide solutions to the problems that have been encountered. This study uses the design thinking method in producing design solutions. Observations were made on the users of the workbench first and then informal interviews related to the level of work comfort were carried out. To support the production process, material selection and product finishing are also carried out in order to obtain products that have good quality. Next, analysis of user needs is carried out to generate design ideas. The result of this study is the design of a multifunctional workbench by considering the complexity of work requirements in order to support the quality of the user's work. This workbench design can be used as a reference for product development, especially on the design of a workbench that can be used in a design studio.]]>

<![CDATA[Rivers are ecosystems that play an important role in the lives of living things around them. The river is not balanced if there are disturbances such as activities around it. Candipari River is one of the polluted rivers which is influenced by the activities in the vicinity. This study aims to determine the quality of river water using the macroinvertebrate community structure (diversity index, dominance index, and BMWP-ASPT). This research uses a biomonitoring method with macroinvertebrate bioindicators, and the retrieval technique uses kicking and jabbing techniques. Measurement of water quality can be seen based on the biological components contained in the water. These biological components are found in water such as macroinvertebrates. These macroinvertebrates can be used as bioindicators, by knowing the role of macroinvertebrates as bioindicators to determine water quality. Analysis of macroinvertebrate data can be identified and calculated by determining the index value. The results of the water quality research based on the BMWP-ASPT method are that at station 1 is a river in the Very Polluted category with a value of 3.57, at stations 2 and 3 a river in the Moderately Polluted category with a value of 4.]]>

<![CDATA[Pelayanan air minum Kota Malang diselenggarakan oleh Perumda Air Minum Tugu Tirta Kota Malang menggunakan kombinasi sistem perpompaan (73%) dan sistem gravitasi (27%). Dominasi sistem perpompaan mengakibatkan biaya energi di Perumda Air Minum Tugu Tirta Kota Malang (Rp 478/m3) lebih tinggi dibandingkan rata-rata nasional (Rp 345,77/m3). Lokasi penelitian pada sistem distribusi Sumbersari dipilih karena operasional pompa berjalan selama 24 jam langsung melayani pelanggan. Pompa eksisting beroperasi mengikuti fluktuasi debit penggunaan pelanggan yang mengakibatkan penggunaan energi menjadi tidak efisien. Hal ini terjadi karena pompa beroperasi normal saat pemakaian air minimum pada jam pelayanan minimum (malam hari). Penelitian ini menganalisis peningkatan efisiensi energi pada Sistem Distribusi Sumbersari melalui skema pemasangan Variable Speed Drive (VSD) yang disimulasikan menggunakan aplikasi Epanet 2.0. Hasil analisis teknis menunjukkan bahwa pemasangan VSD dapat meningkatkan efisiensi pada sistem eksisting dengan menghasilkan penghematan tagihan listrik sebesar 10,16% dan Specific Energy Consumption (SEC) meningkat semula 0,38 kWh/m3 menjadi 0,35 kWh/m3.]]>

<![CDATA[The invention relates to the design of a reactor for producing biodiesel. This reactor consists of three process, reactor tubes (esterification and transesterification processes), washing tubes (washing and settling), and drying-evaporating tubes. This reactor is designed to process used cooking oil which contains high free fatty acids into biodiesel with a batch system. In operation, this reactor is equipped with a DC motor, stirrer, heater, DC pressurized pump, sprayer, and condenser. Additional devices are installed such as speed control, thermocouple, and timer so that the reactor can be operated automatically. The method of the present invention begins with an esterification reaction in which the molar ratio of oil and methanol is 1: 6 using an H2SO4 catalyst of 3% by weight of oil. Reflux treatment with a temperature of 50ºC at a speed of 300 rpm for 60 minutes. The results of the esterification process are then allowed to stand for one hour and the triglycerides are separated. For the transesterification process, the molar ratio of oil and methanol is 1: 6 using a NaOH catalyst of 0.5% by weight of oil. Reflux treatment with a temperature of 60ºC at a speed of 400 rpm for 60 minutes. Then it was allowed to stand for one hour and the biodiesel and glycerol were separated. The biodiesel is then washed with 50ºC warm water by spraying. After the washing process, it is then heated to a temperature of 110ºC. This method is able to convert used cooking oil waste into biodiesel with 95% yield and acid number below 0.5 mg-KOH/g (according to SNI 7182-2015 standard).]]>
