Abstract

The main source of energy for humans is natural resources derived from fossils. Scarcity and rising oil prices will continue to occur due to its non-renewable nature. This must be immediately balanced with the provision of alternative energy sources that are renewable, abundant and cheap so that they are affordable by the wider community. The use of briquettes is based on the increasing price of petroleum in the global market. Charcoal briquettes are charcoal that is further processed into briquettes (special and more attractive appearance) that can be used for daily purposes. This study aims to determine the best raw materials in making quality briquettes. The method used in this research is an experimental method with experiments in the laboratory. The design used is a completely randomised design (CRD) consisting of 5 treatments as follows, P1: 100% corn cob, P2: 75% corn cob + 25% rice husk, P3: 50% corn cob + 50% rice husk, P4: 25% corn cob +75% rice husk and P5: 100% rice husk. Observation data were analysed using Anova (analysis of variance) at the 5% level. If there is a significant difference, then it is continued with the honest real difference test (BNJ) at the real level of 5%.  The lowest value of water content was P5 which was 47.44%, in the stability of the smallest shape change was P1 4.0%, the least particle loss was P1 0.35% and the longest burning time was P3 at 113 minutes. Based on the research results, the best treatment is P3 where the moisture content value is 47.64%, with particle loss of 0.77%, and the longest burning time is 113 minutes.

Abstract

Compost can be defined as the result of the decomposition of organic matter, while composting is a process in which organic matter is decomposed biologically, especially by microbes that utilize organic matter as an energy source. The effect of adding hydrogel to compost is a soil conditioner that focuses on water and nutrient retention so that it can reduce the use of irrigation water and increase the ability of plants to grow. The application of hydrogel and compost can improve physical properties such as bulk density, porosity, number of pores, water content of field capacity, water content of harvesting wilting point, available water, chemical properties, and soil biology. This study aims to determine the composition of the addition of hydrogel to tablet compost made from bio-slurry which is most appropriate for the moisture content and hardness of tablet compost. The method used in this research is experimental with direct testing in the laboratory. The results of the study The higher the addition of hydrogel, the higher the water content because there is still bound water trapped in the hydrogel and the best tablet compost or the highest water content was obtained in the P5 treatment, which was 18.35%, and the addition of hydrogel caused the tablet compost to become soft and elastic. so hardness is easier to destroy. The results of the analysis show that the best tablet compost hardness value is found at P0 of 97.0000 Newton

Abstract

Dry land is productive land that can operate all year round, but with minimal water availability it is one of the obstacles for chili farmers. Therefore, the right solution for this problem is by applying drip irrigation techniques. The purpose of this research was to design and test the performance of the design on chili cultivation in dry land. This study used an experimental method with a direct experimental design on community agricultural land, by making 3 treatment groups, namely P1: surface drip irrigation, P2: subsurface drip irrigation, and P3: open channel irrigation. In this study, the parameters to be studied were designing and conducting performance tests on emitter discharge, water drop uniformity, and wetted areas. The results showed that the drip irrigation design consisted of several components, including primary reservoirs, secondary reservoirs, emitters and pressure regulators. The results of the performance test of the drip irrigation technique design can be said to be feasible to apply based on the discharge value and the drop uniformity coefficient, and the growth of chili plants, both with subsurface and above-surface drip irrigation techniques, does not have a significant effect. So it can be concluded that the method of providing water with subsurface and above-surface irrigation is both said to be effective and efficient

Abstract

One alternative energy source for making organic waste which can be renewed is pineapple waste and tofu waste. Biogas produced from these two materials is environmentally friendly so it does not disturb the environment. The purpose of this research was to determine the changes in temperature and pH that occurred during the formation of pressure and volume of biogas. The method used in this study was an experimental method using a completely randomized design (CRD). There are 4 treatments in this study, namely T1: pineapple waste; T2 : tofu liquid waste; T3 : addition of tofu solid waste; and T4 : addition of tofu liquid waste and tofu solid waste. The measurement results were then analyzed using analysis of variance (ANOVA). If significantly different results were found, a further test was carried out with BNJ. The results showed that the addition of tofu waste significantly affected the temperature, pH, pressure and volume of bioga. The average temperature for each treatment was 28oC, while the highest pH was 8.55. The highest pressure calculation results were found at T4 of 109.42 N/m2, while for the highest volume it was found at T4 of 0.000016642m3. Based on the description above, it can be concluded that the addition of tofu waste has a significant effect on the formation of biogas

Abstract

This research aims to design and build an alcohol distillation machine made from duku fruit using a refrigerator cooling system and a box cooler as a condenser. The distillation machine utilizes a heating furnace to produce ethanol vapor from fermentation, which is then condensed in a cooled box cooler. Tests were conducted with variations in furnace temperature (110°C, 125°C, 140°C, and 155°C). The results show that the higher the heating temperature, the volume of distillate produced increases, from ±132 ml to ±330 ml. However, the ethanol content remained relatively low (10-20%) due to the low initial ethanol content of the fermentation and only one-stage distillation. These results show that the design of the device can function well on a laboratory scale, although further distillation is needed to increase the ethanol content. This research is expected to be the first step in developing a small-scale ethanol distillation device that is efficient and easy to implement.

Abstract

This study aims to determine the effect of cocopeat and hydroton growing media on the growth of tomato plants (Lycopersicum esculentum Mill.) in polybag cultivation systems. The research used an experimental method with a Completely Randomized Design (CRD), comprising six treatments and four replications. Observed parameters included plant height, leaf number, root length, and fresh and dry plant weights. The results showed that treatment P5 (50% soil + 50% hydroton) yielded the best outcomes across most parameters, such as plant height (47.75 cm), leaf number (12.50), root length (24.75 cm), and fresh stem weight (24.75 g). Conversely, treatment P2 (100% cocopeat) showed the lowest growth results. The study concludes that a combination of soil and hydroton is the most effective growing medium for supporting tomato plant growth. Further research is recommended through the generative phase to evaluate yield effects.
