Abstract

Used oil more commonly referred to as used cooking oil is household waste that contains carcinogenic compounds which are very dangerous if consumed by the human, so that it does not become waste in the community can be used as raw material for making biodiesel. Used cooking oil processing can be done with the use of adsorbents so that used cooking oil becomes clear and its quality can be maintained. Palm Oil has the potential to be used as carbon which functions as an Adsorbent in the refining of used cooking oil. In this study, palm fronds were carbonized using pyrolysis with a temperature of 3500C then mashed and sifted with mesh sizes of 50, 70, and 100 mesh. Followed by the activation process using 0.1 M sulfuric acid solution (H2SO4) for 3 hours and then dried using an oven. The results of the study showed that the best turbidity was an adsorbent measuring 100 mesh with a mass of 4.5 grams, the final turbidity obtained with a value of 15.9 NTU with a total turbidity reduction of 108.6 NTU.

Abstract

In making cement, of course, it has to go through processes that the factory. One of the processes in making cement is grinding and drying raw materials, namely the Raw Mill. Raw Mill is the initial stage in making Raw Mix where in the Raw Mill milling, drying, mixing, and separating materials such as limestone, silica, clay, and iron sand occur. Raw Mix is the main ingredient in making clinker which is the main raw material in making cement. The quality of the Raw Mix is very influential in making cement. Where in the process of making this Raw Mix there are changes in quality. Therefore, researchers want to know the main problems that exist in the differences in the quality of different Raw Mixes. In this case, researchers found several problems, including the quality of the raw materials in storage which was not good, then there were problems in the Raw Mill itself, where there were several inner mill parts that were experiencing wear and tear and had to be replaced. After being replaced, the quality of the Raw Mix is obtained which meets the standards and the total balance value of the Mass Balance is 606124.31 tonnes/hour and the total heat lost is 0.071 KJ.

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

Supercapacitors are increasingly developing energy storage devices because they have advantages over conventional batteries and capacitors, such as high power density and long cycle life. Electrolytes are solutions that contain ions and function as electrically conductive media. In chemistry, electrolytes usually consist of acid, base, or salt solutions. The electrolyte used in supercapacitors plays a crucial role in achieving the desired power and energy density. In general, electrolytes are divided into two types based on their phase form, namely liquid and solid or gel electrolytes. Liquid electrolytes can be acids, bases or salts. While gel electrolytes are electrolytes that are denser in nature so that they can reduce leakage.

Abstract

One of the solid wastes from oil palm is the frond, which can be utilized to produce briquettes an alternative fuel. This study investigates the utilization of oil palm frond waste and sugarcane bagasse for briquette production, using different binders like tapioca flour and pulp at concentrations of 3%, 5%, and 8%. The research methodology involved comparing the moisture content, ash content, and calorific value of each treatment applied. The results showed that briquettes with 3% tapioka flour binder produced the best quality, with a moisture content of 3.6%, ash content of 4.4%, and a calorific value above 6,000 cal/g, meeting the quality standards of SNI 01-6235-2000. The implications of these findings indicate the potential of biomass briquettes as an environmentally friendly alternative energy source. However, this study was limited to laboratory testing without application trials or economic analysis. Further research is recommended to evaluate production scale and economic feasibility.

Abstract

Indonesia is recognized as the world's leading producer of palm oil (Elaeis guineensis Jacq.), which contributes to a substantial accumulation of oil palm biomass waste. Among these, oil palm fronds present a promising potential as low-cost and eco-friendly adsorbent materials. Concurrently, the repeated use of cooking oil generates used cooking oil, a waste product that poses significant health risks due to the accumulation of harmful compounds. This study explores the application of oil palm frond-based adsorbents for the purification of used cooking oil through an adsorption mechanism. Experimental results revealed that the optimal adsorbent performance was achieved using 4.5 grams of adsorbent with a particle size of 100 mesh, which successfully reduced the turbidity of used cooking oil to 28.5 NTU, with a total adsorbed turbidity value of 95.5 NTU. Kinetic modeling indicated that the adsorption process followed a pseudo-second-order model, supported by a high correlation coefficient (R² = 0.9983), suggesting that the adsorption mechanism is dominated by chemisorption involving chemical interactions between the adsorbent surface and the contaminants in the oil.

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

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
