Abstract

ABSTRACT This research is conducted to determine the characteristics of Masin made from rebon shrimp with the addition of various Masin’s starter (Starmas). This is designed using completely randomized design with single factor; starter concentrations. Chemical characteristics (water, protein, pH value), sensories (color, texture, aroma, taste) and microbiological (total LAB) were observed. Data were analyzed by analysis of variance (p-value 5%) using Co-Stat Software any significant differences tested using Honestly Significant Differences Test (HSD). Total LAB is analyzed using qualitative method. The addition of various starter concentrations had a significant effect on water, protein, pH value, texture and taste preference level, but did not significantly affect on color and aroma. Total LAB in each treatment increased when the consentration of starter increased. The starter’s addition potentially change the chamical characteristics, sensories and microbioloical of Masin rebon shirmp.

Abstract

Combustion of coal in coal-fired power plants produces air pollution such as SO2, NOx, CO2, and Particulates. The Jeranjang power plant in West Lombok Regency uses 300,000 tons/year of coal to generate 75 MW of electricity. It can be a large potential for environmental pollution. This research aims to simulate the potential of SO2 and CO2 exhaust gas dispersion to the environment and the fatality percentage caused by burning the Jeranjang coal power plant using the Gauss Model. The research was conducted by a literature study and direct observation of PLTU Jeranjang. After that, in this research, the SO2 and CO2 concentration were calculated. At the end of the study, estimating the potential dispersion and fatality percentage by SO2 and CO2 gas was also calculated around the Jeranjang power plant. The results are SO2 dispersion with a dispersion mass of 0.145 kg/sec from a distance of 2,000 to 46,000 m increased from 1x10-45 to 1.9x10-5 ppm and decreased to 0 ppm. The fatality percentage generated is 0%. The CO2 dispersion potential into the environment without a mass of 12.378 kg/sec increases at a distance of 2,000 to 58,000 m, from a concentration of 2.7x10-65 to 0.00184 ppm. The CO2 concentration decreases to 0 ppm. The fatality percentage generated is 0%. The calculation of settlement dispersion around the PLTU Jeranjang can be safe from SO2 and CO2 dispersion, and the fatality percentage generated is 0%.

Abstract

Candlenut (Aleurites mollucana) is one of the biggest potentials, especially in Sumbawa Regency. Apart from being a spice, Candlenut also produces waste in the form of shells with a very large carbon content. So that in this study, the use of candlenut shells as adsorbent was carried out using potassium permanganate or KMnO4. The way it works in this research is by doing a charcoal process on the hazelnut shell waste as the carrying substance. Basically, there are 3 stages in this research, including the carbonization of candlenut shells so that they become charcoal using a drum furnace that has been designed by yourself. Subsequently, the composite beads were sieved by using a 100 mesh sieve. Then KMnO4 is added to the mashed charcoal. The variations in the weight of KMnO4 used are 15 grams, 30 grams, and 45 grams. At the test stage, it was carried out by testing the chemical characteristics of the water content, ash content, and analysis of the best samples. At the end of the study, physical and chemical tests were also carried out on composite beads. The results showed that the best water and ash content was found in the amount of addition of KMnO4 compound at 15 grams, namely 7.33% and 7%, respectively. These results indicate that composite bead products have met the SNI 06–3730-1995 standards. For the effectiveness of absorption of ethylene compounds, the resulting composite beads required 15 grams of KMnO4 for the best absorption of 6.1% ethylene.

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

Gasifikasi menggunakan limbah padat kota (MSW) berdampak pada peningkatan kualitas lingkungan dan peningkatan pasokan listrik untuk daerah-daerah yang sulit dijangkau, khususnya di Indonesia. Namun proses gasifikasi membutuhkan proses pengujian kualitas terlebih dahulu agar dapat menghasilkan produk syngas dan kelistrikan yang maksimal. Maka dalam penelitian ini dilakukan proses pengujian pengaruh variasi Air Fuel Ratio (AFR) terhadap kualitas proses gasifikasi (Cold Gas Efficiency (CGE), Carbon Conversion Efficiency (CCE), dan specific fuel consumption (sfc) atau konversi konsumsi spesifik). Penelitian dilakukan dengan melakukan proses gasifikasi dengan tipe downdraft pada nilai AFR 0,5; 0,51; 0,53; 0,54; 0,55. Hasil penelitian ini menunjukkan adanya peningkatan nilai syngas seiring dengan peningkatan nilai AFR. Sedangkan nilai CGE meningkat seiring dengan meningkatnya AFR proses gasifikasi MSW. Peningkatan terjadi dari 9 menjadi 13%, meskipun hasil ini masih sangat rendah. Di sisi lain, CCE juga mengalami peningkatan dengan meningkatnya AFR gasifikasi MSW. Peningkatan nilai terlihat dari 33-43%. Hasil ini juga masih tergolong kecil, artinya efisiensi konversi karbon pada proses ini sangat rendah. Pada akhirnya, dapat dilihat bahwa nilai scf menurun dengan meningkatnya AFR. Penurunan yang didapat adalah dari 5,3 menjadi 2.
