Abstract

ABSTRACTthe purpose of this research was to obtain the mixture performance of bioethanol and premium compared with Pertamax to power (P), torque (T), fuel consumption rate (mf), specific fuel consumption (sfc), and average effective pressure (mep) on a 9 HP gasoline engine and examined the blend performance of bioethanol-premium which is find out to gain or equivalent to Pertamax. This type of research is experimental research. The initial fuel used is P (Pure Pertamax), E-10 (10% Bioethanol and 90% Premium), E-30 (30% Bioethanol and 70% Premium), and E-50 (50% Bioethanol and 50% Premium). Data analysis used descriptive analysis, which describes the numerical data obtained from experimental testing and formula calculations. Results of this study showed that E30 was closest to Pertamax performance comparing to other fuels, and is even superior in terms of MF and SFC. Proved by stability torque from 2000-3500 rpm and more superior from Pertamax at 2000-2500 rpm, that difference value with in 0.655 and 0.065 Nm. The power of E30 was closest to Pertamax performance at 3500 rpm with in difference value of 0.11 KW. As well as had the lowest rate of fuel consumption rate (mf), most lowest specific fuel consumption (sfc), and the average effective pressure (mep) that closest to Pertamax performance at 2500 rpm, within difference of 57.69 kPa from all types of the fuel was examined. Keywords: Bioethanol, Gasoline Engine, Engine Performance ABSTRAKTujuan penelitian ini adalah memperoleh performa perbandingan campuran bioetanol dengan premium dibandingkan Pertamax terhadap daya (P), torsi (T), laju konsumsi bahan bakar (mf), konsumsi bahan bakar spesifik (sfc), tekanan efektif rata-rata (mep) pada motor bensin 9 HP dan meneliti performa campuran antara bioetanol-premium yang mendekati atau setara dengan performa pertamax. Jenis penelitian ini adalah penelitian eksperimen. Bahan bakar yang digunakan adalah P (Pertamax murni), E-10 (10% Bioethanol dan 90% Premium), E-30 (30% Bioethanol dan 70% premium), dan E-50 (50% Bioethanol dan 50% Premium). Teknik analisis data yang digunakan adalah analisis deskriptif yaitu mendeskripsikan data numeric yang diperoleh dari pengujian eksperimen dan perhitungan rumus. Hasil penelitian menunjukkan penggunaan biopremium E30 paling mendekati pertamax dibandingkan dengan bahan bakar lain bahkan lebih unggul dari segi mf dan sfc. Hal ini dibuktikan dengan torsi yang paling stabil dari rpm 2000-3500 dan lebih unggul dari pertamax pada rpm 2000-2500, selisih 0,655 dan 0,065 Nm. Daya paling mendekati pertamax pada rpm 3500 dengan selisih 0,11 KW. Laju konsumsi bahan bakar terendah dari keempat jenis bahan bakar. Konsumsi bahan bakar spesifik terendah dari keempat jenis bahan bakar. Dan tekanan efektif rata-rata paling mendekati pertamax pada rpm 2500, dengan selisih 57,69 kPa. Kata Kunci : Bioethanol, Motor Bensin, Performa mesin

Abstract

ABSTRACTWaterwheel performance failure caused by many factors. One of the main causes is accumulation of organic material such as food waste, detritus, aquatic plants and bacteria that stick in leaves of the pinwheel. The aim of this research to find out how much influence the dirt crust that sticks to the waterwheel wheel has on its performance. The benefits of this research are expected to provide recommendations about good maintenance for water mills. The data analysis method uses Correlation and Regression analysis using SPSS 22 software. The results of data analysis show the relationship or influence of several parameters on the performance of the pinwheel. The model of the relationship between the length of shrimp rearing (Day of Culture) and the weight of the waterwheel wheel resulting from regression analysis forms an exponential equation model Y = 4,363 X 2,718^(0,006.x). The model of the relationship between the weight of the wheel crust and the temperature of the electric motor resulting from regression analysis forms an exponential equation model Y = 29,940 X 2,718^(0,041.x). The model of the relationship between the weight of the wheel crust and the wheel rotation of the water wheel resulting from regression analysis forms a linear equation model Y = 165,103 +(-13,424)x. The model of the relationship between the rotation of the water wheel wheel and dissolved oxygen levels in the water (Dissolved of Oxygen /DO) resulting from regression analysis forms a linear equation model Y = 3.275+0.20x.ABSTRAKKegagalan kinerja kincir air dapat disebabkan oleh banyak  faktor. Salah satu penyebab utamanya adalah adanya akumulasi bahan organik seperti sisa pakan, detritus, tumbuhan air dan bakteri yang menempel di daun roda kincir. Proses ini mungkin diperparah oleh kondisi lingkungan tambak yang kurang terjaga, seperti tingginya nutrien tersisa dan kepadatan udang yang tinggi. Selain itu, faktor iklim seperti temperatur air yang tinggi dan paparan sinar matahari yang intens juga dapat memicu pertumbuhan mikroorganisme, alga, dan bakteri, yang kemudian dapat menempel pada permukaan daun roda kincir air dan membentuk lapisan kerak kotoran atau biofouling. Tujuan dari penelitian ini adalah untuk mengetahui sampai seberapbesar pengaruh kerak kotoran ( biofouling ) yang menempel di roda (Wheel ) kincir air terhadap kinerjanya. Manfaat penelitian ini diharapkan dapat memberikan rekomendasi tentang maintenant yang baik terhadap kincir air. Penelitian ini merupakan  studi kasus pada tambak Udang Vanname intensif CV. Panen Sehat Sejahtera Blitar Jawa Timur. Metode analisis data menggunakan analisis Korelasi dan Regresi melalui software SPSS 22. Hasil analisis data menunjukkan hubungan atau pengaruh beberapa parameter terhadap kinerja kincir air sebagai berikut. Model  hubungan antara lama pemeliharaan Udang ( Day of Culture )  dengan berat roda (Wheel) kincir air yang dihasilkan dari analisis regresi membentuk model persamaan eksponensial  Y = 4,363 X 2,718^(0,006.x). Model  hubungan antara berat kerak roda kincir (wheel) dan suhu motor listrik yang dihasilkan dari analisis regresi membentuk model persamaan eksponensial  Y = 29,940 X 2,718^(0,041.x). Model  hubungan antara berat kerak roda kincir (wheel) dan putaran roda (Wheel) pada Kincir Air yang dihasilkan dari analisis regresi membentuk model persamaan Linier  Y = 165,103 +(-13,424)x. Model  hubungan antara putaran roda (wheel) Kincir Air dengan kadar oksigen terlarut dalam air (Dissolved of Oxygen /DO) yang dihasilkan dari analisis regresi membentuk model persamaan Linier  Y = 3,275+0,20x.

Abstract

Microbubble generator (MBG) is one of aerator that used to enhance dissolved oxygen (DO). Microbubble generator is designed with the diameter of 45 mm for water inlet and reduced to the diameter of 10 mm. The air inlet has the diameter of 18 mm and increased to 45 mm so that it can be equal with the nozzle diameter. The nozzle is the outlet of water and air is reduced to the diameter of 22 mm. The test results showed that the minimum DO measured of 6.3 mg/l, and the maximum of 6.9 mg/l. The increase in DO ranged from 2.3 – 2.7 mg/l. The measured electric motor temperature ranged from 45°C - 55°C for 9 days of testing so that it can be stated that the microbubble generator can be used for 1 cycle of aquaculture.
