Abstract

North Musi Rawas Regency is a new district that has a wealth of natural resources, one of which is water resources. However, the use of water resources is not maximized and not properly inventoried, especially in disaster activities such as floods and forest fires. This is because the condition of the area is difficult to reach, making it difficult for local governments to map the situation and potential of water resources. The increasing development of science and technology requires local governments to have special data collection systems for natural disaster situations and water resources, especially those that can be accessed by the public. The aim of this research is to identify natural disaster situations and water resource potential based on field data taken and provide information regarding natural disaster data (floods and forest fires) and water resource potential that can be accessed by the government and the public. It is hoped that the results of this research will provide a general overview of information regarding natural disaster situations and water resource potential in North Musi Rawas Regency so that it can become a work reference and decision/policy making for the Government/relevant agencies in disaster emergency response preparedness efforts and the development of sustainable water resource potential development. . The research location is North Musi Rawas Regency. The research method is a field survey. The survey carried out was to collect data and coordinate points for floods and forest fires as well as potential water resources. Next, hydrological system identification and data inventory will be carried out. Then the data was analyzed using a GIS application. The map contains information on disaster point data (floods and forest fires), water facilities and infrastructure as well as water resource potential as part of public information.

Abstract

This current research aimed to plan an optimal and scheduled production to minimize defects in production quantities, excess or shortage of production quantities with minimum costs. The method used was Dynamic Progamming to develop optimal scheduling, by forecasting average production using the Autoregressive Integrated Moving Average (ARIMA) model. The ARIMA was employed to forecast the average amount of production data of CV Shohat Gorontalo which were the data for the last 24 weeks or during 6 months. The result obtained was that the minimum cost was always obtained at the inventory figure I = 0, because having less inventory or even no inventory would reduce the total cost due to the small holding costs when compared to production costs. The cost incurred for the production schedule during the July- December of 2023 period was IDR 9,161,954,550. In addition, the data were the optimal result in minimizing production costs using the Dynamic Programming method. Abstract written in English. Abstracts are written in a sequence that contains the purpose of research, the methods used in research, research results, conclusions, suggestions, and research implications. The abstract is concise, concise and written in one paragraph (maximum 200 words) with single space, Times New Roman font and 10 font sizes

Abstract

Abstract: Experimental Study of the Effect of a Mixture of Ethanol and Pertamax on Fuel Consumption of a 125cc Injection Motorcycle. Currently the need for petroleum is quite high. This is because transportation and industry still rely on petroleum as the main fuel. Ethanol has similar properties to Pertamax fuel which can be applied to every vehicle, especially two-wheeled vehicles. The aim of this research is to find out how the addition of ethanol to Pertamax fuel affects the amount of fuel consumed by injection motorbikes. The mixture percentages that will be tested are E10+P90, E20+P80, and E30+P70 respectively, and then the consumption results are compared with tests using pure Pertamax (E0+P100). The test results show that the use of Ethanol-Pertamax mixed fuel can be reduced when the percentage of the ethanol mixture is below 50%. Where the lowest fuel consumption is the E30+P70 mixture at 16.4% compared to pure Pertamax consumption.
