Abstract

Rice is one of the most important cultivated plants for human survival. The activity of cultivating rice plants becomes a livelihood for most of these residents, so the success rate of the amount of rice harvested becomes very important because they depend on how much rice can be harvested, disease diagnosis is very important for farmers, this is very important to reduce economic losses due to diseases that cause crop failure. Therefore, when dealing with rice diseases, an expert is needed to make diagnoses or solutions to rice diseases. However, an expert does not know when to come to the village, and farmers also do not understand all rice diseases. Therefore, a web-based expert system application using the forward chaining method is proposed to represent an expert to help farmers diagnose and solve diseases of rice plants with existing symptoms.

Abstract

The availability of clean water is a very basic need to support the lives of village communities. Tamangil Nuhuten Village, located in the South Kei Besar area, Southeast Maluku, faces various challenges in the supply and distribution of clean water. This study aims to analyze the clean water distribution scheme in Tamangil Village, Southeast Nuhuten. The results of the study show that the distribution of clean water in Tamangil Nuhuten Village still faces various challenges, especially in terms of accessibility, infrastructure, and meeting the needs of the community. Of the three main springs that are sources of clean water, only Spring A has the highest discharge of 10 liters/second with the closest distance of 1.5 km from settlements. However, only 20% of households have direct access to simple water pipelines, while the other 80% have to transport water manually, with a daily fulfillment rate of only 35%. This condition causes most people, especially those who live far from water sources, to spend more than two hours per day just to get clean water. This inequality of access has an impact on people's quality of life, including an increased risk of waterborne diseases. Data shows a 15% increase in diarrhoea cases during the dry season due to the use of water from unprotected sources. In addition, the time spent transporting water reduces people's productivity in economic activities and children's education. Limited distribution infrastructure and low community participation in clean water management are the main obstacles in creating an efficient distribution scheme.

Abstract

As one of the largest cities in Indonesia, the City of Surabaya has an obligation to provide excellent health services for its residents. It goes without saying that Surabaya City Government is required to provide a General Hospital that can receive referrals from the government-owned Community Health Centers. For this reason, the Surabaya City Government built the East Surabaya Hospital which is located in Rungkut Sub-District. East Surabaya Hospital is a strategic project that requires investment feasibility analysis. The East Surabaya Hospital investment feasibility analysis was done by applying the Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP) and Benefit Cost Ratio (BCR) parameters. After the feasibility analysis results were obtained, a sensitivity analysis was done on changes in management costs and the amount of health service levy rates for each Fees alternative. Based on the results of the investment feasibility analysis of 4 (four) Fees alternatives, there are 2 alternatives that can be concluded as worthy investments, which are alternative 1 and alternative 3. Meanwhile, alternative 2 and alternative 4 are not feasible since the NPV parameter shows negative values and the IRR value is lower than the MARR value. However, based on sensitivity analysis, alternatives 2 and 4 can be feasible if alternative 2’s service rate is increased by 13.2%, and alternative 4’s service rate is increased by 2.3%. The opposite applies in alternative 1 where the investment might become unfeasible if the service rate is reduced by more than 5.4% and alternative 3 might become unfeasible if the service rate is reduced by more than 2.5%.
