Abstract

Water is an important supporting factor in humanlife. The problem of clean water in an area is managed by Perusahaan Daerah Air Minum (PDAM) Surabaya. PDAM Surya Sembada as a water management company in Surabaya is expected to be able to distributethe needs of clean water, however, in the distribution network, sometimes experiencing problems that cause water is not fully channeled to the customer, to overcome this problem, the Causal Loop Diagram approach is used to identify the cause of the water loss,after knowing these factors, we have been made model with Causal Loop model,to calculate the water loss that occurred, in PDAM Surya Sembada Surabaya especially DMA 109 using Infrastructure Leakage Index (ILI) method. The Causal Loop Diagram approach, various causes of water loss include: physical water loss caused by reservoir leakage, transmission line leakage and distribution pipeline leakage; non physical water loss caused by meter fault, wild connection and water theft. Based on the data obtained, obtained NRW value at DMA 109 of 439.455.72 m3 / year or by 25% with a loss of 329.591.8 m3 / year. Service pipe leakage up to the customer meter is 1.757.822.8 m3 / year.

Abstract

Layout arrangements are vital for improving quality, productivity and corporate image. A production requiring multiple machines and a production process flow that is too long necessitates the preparation of a detailed layout in order that there is no transfer flow movement in the production process. This study aims to make the production process has a total minimum displacement moment and increase employee performance. From the analysis conducted at PT. XYZ that produce bread shows the existence of long distance, motion behind and congestion during material handling. The result of analysis by using method from to chart shows that the distance of material transfer distance is 73, 70 meter, total frequency of material transfer 35 times and mileage with total 1,901 meter. The result of analysis using activity relationship chart where spray & seeding (J) and split machine (K) departments were moved close to proofing room 1 (H1) and proofing room 2 (H2) facility, rack & pan 1 (I1) facility was moved near With rack, tray & pan cleanning (G) area facilities and the sieving flour (B) and formula room (D) departments being moved close to the process area 2 (C2) facility.

Abstract

Salt in the main need for humans, In the process of shrinkage of salt products become the expected result is always increased because in the islands of Madura who have high salt income can be utilized. Light focus can be used through convex convex lens to increase sea water shrinkage so as to accelerate evaporation as well Get shrinkage of salt water salt raw material quickly. From observations made in May - June 2017 can be obtained data focusing light through convex convex lens is by focusing the sun on convex lens that is directed at sea water, so it can shrink the water faster. Acquisition of water depreciation using the tool obtained 95,000 cc / 95 liters, while 47.000 cc / 47 liters obtained from without tools. From this study it can be concluded that the value obtained yields a positive value, where the use of the tool from the volume of each volume filled 100 liters with a ratio of 1: 1 from the analysis obtained from using a tool faster 56% using tools with upper 14322.90 Of the 99% confidence interval received. So from the shrinkage using a faster tool, the depreciation of sea salt raw materials with convergent convex lenses can be applied directly as a technological reasoning.

Abstract

Various fire infrastructure in Surabaya has been built, but the number of fire incident is less suitable with the standard of disaster response time. This study was conducted to determine the distribution of minimization of fire engine mileage in SIER Industrial Area of ​​Surabaya. The analytical method used is qualitative descriptive by comparing existing condition, criteria, and policy review that exist in SIER Industrial Area of ​​Surabaya with data of fire service post service in Surabaya City to know unreached area of ​​fire post service and have high risk potential Will be a fire disaster in the SIER Industrial Area of ​​Surabaya. Next determine the factors and criteria for determining the location of firefighting post based on existing policy studies and conditions. Factors determining the location of firefighting in Surabaya City is a function of the building based on the type of land use, the density of the net population, the density of the building, the range of fire service, the radius of the water supply range, the incidence of fire, the time of fire disaster response, the availability of land, and the class of road. The result of this research is the implementation of building protection management on building function in industrial area, procurement of socialization and education of fire prevention for the community, coordinating with traffic police to facilitate path of location achievement

Abstract

Textile Jaya Gemilang is a textile company that has a cotton fabric finishing unit. In the identification carried out the company still produces waste and has not yet carried out an environmentally friendly process. Therefore efforts are needed to identify waste in the process of finishing woven fabrics to make the process environmentally friendly by considering the level of eco efficiency and eco costs to determine the proposed process that is environmentally friendly. This research includes steps such as analyzing value stream mapping to find out activities that have value added and categorized as NVA. Furthermore, measurements of environmental impacts were carried out with LCA (Life Cycle Analyzing) and then gave a proposal to provide a proposed process with the 6R approach (reuse, reduce, recycle, remanufacturing, recovery and redesign) in the process of finishing cotton cloth obtained by waste, namely in appropriate processing, defect and waiting time . The results of the Life Cycle Assessment showed results for a process of 248.76 pt, for Life Cycle Impact Assessment Damage Category Human Health of 4.8813 DAILY, Damage Category Ecosystem Quality of 310,000 PDF * m2yr and for Damage Category Resources 1615,646 MJ surplus . Eco cost is Rp. 608,425,018.2. Proposed environmentally friendly process by raising the level of green manufacturing to recycling and reuse.
