The problem of product distribution becomes an important topic in a company's transportation system. PT Amanah Prima Indonesia (API) is a national-scale company engaged in the production of juice drinks. With the number of consumers scattered in the Semarang area, it is necessary a solution in the distribution of products in order to obtain operational efficiency. The method used is Nearest Neighborhod Algorithm. The results obtained are: (a) Distance savings of 144.20 Km or 40.06%, (b) Product distribution time can be reduced for 5.15 hours or 30.31%, (c) Fuel costs used obtained cost savings of Rp.108.150, - or equal to 40.06%, (d) Expenses for driver and companion cost is no difference of Rp.600.000, -, and (f) The total cost of distribution is obtained savings of Rp. 108,150 or 12.43%.

The population of Sidoarjo Regency with a relatively high number and growth rate has consequences for the increase of waste produced volume. Increasing of volume waste is directly proportional to the increase in population, meaning that amount of waste produced is increasing (organic and inorganic waste). The TPA center in one of the garbage collection locations in Sidoarjo Regency has exceeded capacity (overload). This research was conducted with the aim of describing initial model of the distribution of waste used, evaluating initial performance model of waste distribution in Sidoarjo Regency, and providing recommendations to propose improvements in the waste distribution model used. The method applied in this study was using simulation. Based on the simulation results, the Third Scenario proposed the route with the most efficient distance, this affected the vehicle's operational time and the operational costs needed.

Transportation problem is just like inventory, this is an activity in logistics area. This activity is possible to make some production in one place and to consume them in another place. The aim of this research were to evaluate the existing network distribution model performance and to provide sugestions to proper the network distribution model used. The applied metode to achieve the goal was Nearest Neighbor Algorithm. The results were: (a) Distance saving was 538,2 Km or 26,59%, (b) Distribution time of product could be reduced to 9,37 hours or 19,07%, (c) Fuel cost could be reduced to 403.650 rupiahs or 26,59%, (d) Driver and assistance cost could be saved to 272.850 rupiahs or 4,5%, and (f) Total of distribution cost could be saved to 676.500 rupiahs or 25,71%.

Pond is one place that is used as a place to cultivate fish, shrimp, and other aquatic animals that can live in brackish water. Changes in water quality upstream and downstream of the pond due to pollutants may affect the ecological balance of waters. Pollutants can be determined by two simple parameters, the biochemical oxygen demand (BOD) and chemical oxygen demand (COD). While the ability to break down pollutants (biodegradability) can be determined using the ratio of BOD/COD. BOD analysis using the Winkler titration method, whereas the COD analysis using titrimetric method. The value of BOD, COD, and the ratio of BOD/COD in the upstream area is 28.00 mg/L, 60.00 mg/L, and 0,467 respectively. While the value of BOD, COD, and the ratio of BOD/COD in the downstream area is 20.00 mg/L, 43.00 mg/L, and 0.465 respectively. Ratio BOD/COD obtained show that the organic pollutants in the pond is biodegradable.

Sidoarjo Regency is a buffer zone for industrial estates in Surabaya, East Java Province. Therefore, the economic growth of the Sidoarjo Regency is increasing along with the development of trade and industrial potential. One of the industries that have grown well in Sidoarjo Regency is the tofu factory. Many tofu craftsmen industry causes an increase in the volume of liquid waste which also flows into water bodies. The purpose of this study was to determine the reduction of TDS and ammonia levels in the tofu factory wastewater treatment in the Sepande area, Sidoarjo Regency, by using a wetland construction with a Typha latifolia remediator. The research stages will be carried out using a laboratory scale using acclimatization as the adaptation stage of Typha latifolia and a constructed wetland reactor as a phytoremediation process. Based on the results and discussion, it can be concluded that there was a decrease in TDS and ammonia levels in the tofu industrial wastewater in Sidoarjo with the Constructed Wetland system. The largest decline in TDS content was in soil media with three Typha latifolia stems and a detention time of four days by 76%. Meanwhile, the most considerable percentage reduction in ammonia levels occurred in sand media with three stems of Typha latifolia and a detention time of four days by 70%.
