Abstract

Saat ini bahan bakar biodiesel yang digunakan untuk mesin diesel umumnya berasal dari CPO (crude palm oil). Penelitian ini menggunakan bahan bakar biodiesel dengan bahan baku minyak kedelai. Tujuan penelitian ini selain untuk mengetahui pengaruhnya terhadap kinerja mesin, diteliti juga efeknya terhadap perubahan temperatur di ruang bakar mesin diesel yang diuji dan emisi gas buang yang dihasilkan. Perlu diketahui bahwa perubahan temperatur di ruang bakar sangat mempengaruhi proses pembakaran yang dihasilkan mesin dan hal masih sangat jarang dikaji oleh para peneliti. Metode penelitian diawali dengan pengujian nilai kalor bahan bakar yaitu B30, B20, B10 dan minyak solar. Untuk pengujian kinerja mesin digunakan mesin diesel empat langkah tanpa modifikasi. Dari hasil eksperimental tampak bahwa terjadi peningkatan nilai pemakaian bahan bakar spesifik yang sesuai dengan meningkatnya komposisi biodiesel minyak kedelai di dalam campuran bahan bakar. Besarnya emisi gas buang CO dan HC mengalami penurunan saat menggunakan bahan bakar B10, B20 dan B30. Data eksperimental menunjukkan bahwa daya maksimum diperoleh 1,26 kW, konsumsi bahan bakar spesifik 373,15 g/kWh dan efisiensi termal maksimum 23,04% saat menggunakan bahan bakar solar. Temperatur maksimum ruang bakar mesin diesel diperoleh saat menggunakan bahan bakar solar sebesar 507,86°C. Data pengujian menunjukkan bahwa temperatur ruang bakar minimum diperoleh saat mesin diesel menggunakan bahan bakar B30 sebesar 388,49°C.

Abstract

The development of the Chinese city site area as a tourism potential in the city of Medan is very important considering the city of Medan does not yet have natural tourism objects that are well managed. The type of study used in this research is descriptive with a qualitative approach where research is carried out to create a tourism development using the Collaborative Management (Co-Management) method. To obtain data and to deepen the implementation of collaborative management, in-depth interviews were conducted with key informants and questionnaires so that the data needed in this study was complete. Data obtained in the field, both secondary data and primary data will be compiled, presented and analyzed with a qualitative approach in the form of exposure which will then be analyzed in accordance with the research problem undertaken. The results of research conducted show that the community has been involved in the development of tourism in the Chinese city site area. But the community is still walking alone in the development of tourism.

Abstract

This study aims to determine the differences in production, revenue, income differences and the feasibility of Ciherang, Inpari 13 and Mekongga rice fields in the study area. To determine the feasibility of Ciherang, Inpari 13 and Mekongga varieties of rice farming, it is feasible from the comparison of revenue and costs in the study area. To find out the efficiency of Ciherang, Inpari 13 and Mekongga varieties in the study area. The average income of paddy farming received by respondent farmers in Labuhanbatu Regency for Ciherang variety is Rp. 14,416,111.11, - per Ha / MT. A Return Cost Ratio (R / C ratio) of 2.29 shows that R / C 1, then this farm is profitable. The biggest acceptance for lowland rice farming in Labuhanbatu Regency was Ciherang variety, followed by Inpari 13 variety, and the lowest acceptance was Mekongga Variety. The R / C ratio indicates that it is still feasible to be cultivated, but in terms of the BEP value of land use, the number shown 1, means that land tenure below 1 Ha will not be able to sustain farmers' income if there is a 10% increase in total production costs with the assumption of production and fixed price (no increase).
