Abstract

The Sembelia Steam Power Plant is located in East Lombok, West Nusa Tenggara and is managed by PT. Lombok Energy Dynamic uses the light coal until 200,000 tons per year. This case can be the environmental pollution. This study aims to calculate the SO2 and CO2 exhaust gases into the environment by the simulation as well as included the %fatality due to coal combustion of the The Sembelia Steam Power Plant with the model of Gaussian. This research was carried out by calculating the SO2 and CO2 concentrations released concentration. At the end of these project, we calculated the SO2 and CO2 released by the dispersion potential and %fatality at four points around it. The result of this research showed that the dispersion mass of SO2 dispersion was 0.096 kg per second (with distance of 2,000 to 46,000 m). This result showed that the increases (6.876x10-46 ppm to 1.276x10-5 ppm), and then showed that the decreases to 0 ppm. % Fatality in this study is 0%. The potential of CO2 dispersion with an outgoing mass of 8,252 kg/second increased (2,000-58,000 m) with a concentration of 62.47x10- 63 ppm to 7.9x10-4ppm. In the other hand, the concentration of CO2 was reduced to 0 ppm. In the end of this study showed that %fatality by the CO2 released is 0%, and the calculation of dispersion at four points around the The Sembelia Steam Power Plant is safe from the SO2 and CO2 dispersion.

Abstract

Ziziphus mauritiana is widely found in Sumbawa arid and semi-arid area. It is a drought tolerant plant which grows in areas with extreme conditions. While information of the utilisation of Bidara seeds as activated carbon is available, there are limited resources that use Bidara woods. Therefore, this study aims to characterize the activated charcoal derived from Z. mauritiana wood which was activated using 25%, 30% and 35% of H2SO4 and NaOH. The moisture content, ash content, volatile matter, fixed carbon, and iodine absorption capacity were investigated and compared to the Indonesian National Standard (SNI. 06-3730-1995). The result showed that NaOH activated charcoal obtained higher quality compared to the H2SO4 activated charcoal. The best activated charcoal was obtained from 35% of NaOH which has 1.19% moisture content, 13.21% ash content, 1.42% volatile matter, 84.73% fixed carbon, and 1892.40 mg/g iodine number. This study concludes that the characteristics of Z. mauritiana activated charcoal (except the ash content) comply with Indonesian National Standard and potentially can be developed as an adsorbent.

Abstract

Tomato (Solanum lycopersicum) is classified as a climacteric fruit that is easily damaged, especially during the storage and shipping process, so proper postharvest management is needed. Postharvest management of climacteric fruit can be overcome by inhibiting the process of respiration and transpiration using activated charcoal. Activated charcoal works by absorbing ethylene gas during the respiration process. This study aims to analyze the use of bidara activated charcoal variations as an inhibitor of tomato ripeness and to examine changes in fruit quality during the 10day storage. The research used One Way Anova analysis with one factor of variation of activated charcoal with control treatment, 1gr, 3gr, and 5gr. Parameters tested were weight loss, Total Soluble Solid, and vitamin C. The use of bidara activated charcoal on tomatoes got the best results in the 5gr treatment with a weight loss value of 0.46%, 0.10 obrix total dissolved solids, and 18.93% vitamin C. Bidara activated charcoal had an effect on weight loss and total soluble solids but had no effect on vitamin C content. Bidara wood activated charcoal can be developed into an absorbent material for tomatoes.

Abstract

The use of organic fertilizers in Indonesia is increasing, this is due to the scarcity of synthetic fertilizers. Organic fertilizers have their own challenges in terms of the concentration they contain. In addition, some organic materials that exist today are very abundant, so it needs to be used as organic fertilizer, one of which is betel leaf. However, betel leaf itself is an additional ingredient that can increase the existing nutrient content. In this study, analysis of the macro elements in organic fertilizers was carried out by adding variations in the amount of betel leaf raw material. The research was conducted using variations of betel leaf extract 2%, 4%, and 6%. The test analysis in this study was in the form of N, P, and K levels. The results showed that the highest N content was in the 4% betel leaf variation, which was 0.1%, the highest P content was in the 2% variation, which was 0.04%, and the highest K content was at 2% variation, namely 0.066%. From these results, it can be said that there was no significant effect of the addition of betel leaf extract on the macro-nutrient content of liquid organic fertilizer.

Abstract

The use of marine products in almost all coastal locations in Indonesia has stagnated in selling value. This is because people in Indonesia have not processed marine products properly. One location that has problems like this is in Labu Ijuk, in the District of Moyo Hilir, Sumbawa Regency. In this activity, Lecturers from the Agricultural Industrial Technology Study Program, Sumbawa University of Technology (TIP-UTS) conducted training for the local community, especially those who work as fishermen. The training carried out was in the form of training in making floss and crackers from the basic ingredients of fish caught by local fishermen. The type of fish used is flying fish with the Latin name Decapterus. This fish is very abundant. After that, the material was given directly by the TIP-UTS Lecturer. The results of this service produce fish floss and fish crackers which must be dried in the sun first. After production was carried out, the team agreed with the community to develop packaging types and marketing methods using several online platforms.
