Abstract

Nanas merupakan salah satu tanaman buah yang banyak dibudidayakan di daerah tropis dan subtropis. Salah satu daerah di Kecamatan Tapung, Kabupaten Kampar, Provinsi Riau dengan penghasil buah nanas yang banyak adalah Desa Pagaruyung. Petani nanas lansung menjualkan hasil panen mereka tanpa pengolahan, namun semenjak masa pandemi covid 19 memasarkan hasil panen nanas mulai sulit dipasarkan. Metode pengumpulan data dilakukan dengan cara analisis dan survey lokasi mitra. Dengan pengabdian ini diharapkan para petani nanas Desa Pagaruyung dapat mengatasi cara pemasaran hasil panen nanas, sehingga dapat membangkitkan kembali perekonomian Desa Pagaruyung.

Abstract

Electrinic Fuel Injection (EFI) a system that supplies fuel from the tank electronically with a mixture of air that suits fuel needs so that vehicle power remains maximum with minimal fuel consumption to produce environmentally friendly emissions. The fuel injection system is an innovation step that is being developed and applied to motor vehicles today. The purpose of the study was to find out the characteristics of the 2007 Honda Jazz I-DSI engine using the parameters of maximum torque, maximum power, average effective pressure (Brake Mean Effective Pressure) and specific fuel consumption (Specific Fuel Consumption). The method used is direct observation of the problems related to this study. Torque as the rotation of the Honda Jazz i-DSI engine shaft has a higher torque. This shows that the Honda Jazz engine has a higher torque value to improve engine performance. Effective engine power occurs at engine shaft revolutions of 1000 to 5000 rpm. The specific fuel consumption of the Honda Jazz engine has a higher specific fuel consumption value of 34.23% than the i-DSI with the PGM-FI (Programmed Fuel Injection) fuel supply system. At 3500 to 6000 rpm, the Honda Jazz i-DSI engine has a higher specific fuel consumption value compared to the PGM-FI fuel supply system. So the use of fuel using the i-DSI engine is more efficient at low revs because it uses 2 spark plugs, so combustion can be maximized. The thermis efficiency of the Honda Jazz i-DSI engine has a higher thermis efficiency value of 11.15%. Thermis efficiency rises when the engine revs up. Then it can be said that the efficiency of the thermis is directly proportional to the rotation of the engine.

Abstract

Conventional handling of biomass waste, such as burning biomass, can cause other problems, and is not effective. Another common handling method is utilizing biomass waste. Second, conventional handling does not significantly reduce the amount of biomass waste. Microwave heating uses several power parameters and activation time to determine the effect of power and activation time on iodine number and surface area [25]. Activated charcoal is used as a raw material because it is hard charcoal and has good quality, and microwaves are used because it saves energy and time. Microwave treatment to study the effect of concentration and time of microwave irradiation separately on iodine number and adsorption capacity. The results of the FTIR spectra show that activated carbon has an –OH group. The results of the adsorption test showed that the activated carbon that had been prepared was able to absorb ions at the optimum concentration. Adsorption isotherm studies were carried out using the Langmuir equation. Microwave irradiation time also has a significant effect on the quality of activated carbon in the microwave irradiation time range
