Abstract

Biomass energy is produced by converting solid raw materials into a more useful compressed form known as briquettes. This study aims to examine the effect of varying compositions of charcoal briquettes using a mixture of cocoa shells and rice husks on the briquette characteristics. The experimental method employs a Completely Randomized Design with four treatments: P1 = 100% cocoa shells, P2 = 75% cocoa shells + 25% rice husks, P3 = 25% cocoa shells + 75% rice husks, and P4 = 100% rice husks. The study finds that the lowest moisture content is in P3 (8.01%), the lowest ash content is in P3 and P4 (4.1% and 3.8%, respectively), the highest calorific value is in P1 (3,658 cal/g), the longest ignition time is in P3 (50 minutes), and the best hardness is in P2 (785.95 N). Based on the results, the best treatment is P3, which achieves a moisture content of 8.01%, ash content of 4.1%, and the longest burning time of 50 minutes.

Abstract

Demand for melinjo chips is high, but the current production method is less efficient in terms of time. The melinjo flattening machine is a new innovation that has the potential to replace the conventional process, thus optimising post-harvest handling. It is expected that the use of this flattening machine can increase work capacity and facilitate the production of quality melinjo flattening products in the future. This study used experimental methodology with a one-factor completely randomised design (CRD) research design. The experiment consisted of three treatments, namely P1, P2, and P3, with amounts of 1000 grams, 2000 grams, and 3000 grams, respectively. Each treatment was repeated three times, resulting in nine experimental units. Observation data were analysed using the BNJ test at the 5% level to determine which treatment had a significant effect on yield. The test results show that the melinjo seed flattener can operate properly. In testing the capacity of the tool shows the greatest working capacity of the machine, P3, which is 28.73 grams/minute.  The processing time test shows that the treatment that produces the most time is P3 of 88 minutes.  In testing the weight of the flattener results show that P3 produces the most with a value of 2516.67 grams. It is necessary to make improvements to the hopper and redesign by calculating the bulk angle of melinjo seeds, so that melinjo seeds can easily go down to the rationing section. In addition, a stirrer is designed for melinjo seeds that are ready to be flaked with the flattening machine so that when roasting with a stirrer, the melinjo seeds that are still hot are immediately put into the hopper so that they can be flattened using the semi-automatic flattening machine.

Abstract

Seawater intrusion in Gili Trawangan, North Lombok Regency, can be identified through groundwater salinity testing. This study aims to evaluate changes in groundwater salinity values as an indicator of seawater intrusion in the region. The test was conducted by taking well water samples and analyzing them at the Lombok Island Health Laboratory. The results showed that the groundwater salinity value before the water withdrawal project by PT Berkat Air Laut in 2012 was 5.00‰. During the groundwater withdrawal project period (2013-2022), the salinity value increased to 5.71‰, and post-project, the salinity value reached 6.07‰. These findings indicate that groundwater in Gili Trawangan was classified as brackish water from the start, with increasing salinity values indicating seawater intrusion. However, this increase is still in the low category, at 0.71‰ during the project and 0.36‰ post-project, so it is not classified as significant water pollution.

Abstract

The 93.55-hectare Mataram Muhammadiyah University Educational Forest has been enriched with eucalyptus and gaharu plants since 2019. In 2024, further enrichment will be carried out with Durian, Avocado, Jackfruit, and Longan plants. The results of previous studies showed that the development plan for Durian plants has a marginal suitability class or S3. This study aims to determine the suitability class and area of land units for Avocado plants as an alternative choice, limiting factors and economic feasibility analysis. Land surveys using the free grid method on 9 land units and land evaluations by matching 14 parameters of land availability and land requirements for Avocado plants, namely soil conditions, climate, and land. The results of the study showed that land suitability for avocado plants was quite suitable (S2) on 3 land units covering an area of 34.15 Ha with limiting factors being texture, soil depth, Total N, Available K and Slope. The land suitability class was marginally suitable (S3) on 6 land units covering an area of 59.4 Ha with limiting factors being slope and soil depth. The investment cost for enrichment of MPTS avocado plants of 100 trees per hectare is Rp. 6,000,000 per hectare and the estimated return on capital is in the 6th year after planting

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

One alternative energy that can be used as a substitute for fuel oil and gas is biomass energy such as briquettes. This study aims to determine the amount of heat, moisture content and ash content of briquettes made using hazelnut shells and glutinous rice adhesives that vary in adhesive concentration and particle size. This study used a complete randomised design (CRD) with variations in glutinous rice concentration of 20%, 30%, and 40% while the particle sizes used were 12 mesh and 24 mesh. The results showed that the adhesive concentration did not significantly affect the test parameters while the particle size affected the moisture content, ash content and calorific value of the briquettes. The highest calorific value was obtained by using 24 mesh particle size with 20% adhesive concentration with a calorific value of 5321 cal/g while the 12 mesh particle size produced the highest calorific value of 4704 cal/g at 20% adhesive concentration. The lowest moisture content value was obtained by using 24 mesh particle size with 20% adhesive concentration with a moisture content value of 6.9% while the 12 mesh particle size produced the lowest moisture content value at 20% adhesive concentration with a value of 7.4%. The lowest ash content value was obtained by using 24 mesh particle size with 30% adhesive concentration with an ash content value of 4.99% while the 12 mesh particle size produced an ash content value of 5.82%. The use of 12 mesh particle size is not in accordance with SNI standards because the heating value produced is still below 5000 cal/gr while the use of 24 mesh particle size is in accordance with SNI standards for all test parameters.
