Abstract

The solution to reduce the use of fossil fuels is by utilizing renewable energy such as solar power, wind power, and hydropower, as well as the utilization of other alternative energy derived from biomass. One of alternative energy from biomass that is very potential is briquettes. Tapuk Village, Limpasu Subdistrict, Hulu Sungai Tengah Regency is one of the producers of Alaban wood charcoal, with grade D charcoal in the form of charcoal flakes and is often regarded as waste. This study aims to determine the physical properties of alaban wood charcoal waste briquettes which include water content, ash content, volatile matter content, fixed carbon content, and calorific value, as well as the potential utilization of alaban wood charcoal waste briquettes. so that residents can use Tapuk Village, Limpasu District, Hulu Sungai Tengah Regency as an alternative fuel to substitute kerosene and LPG. The results showed the physical properties of alaban wood charcoal waste briquettes for 3.66 % water content, 3.15 % ash content, 14.31 % volatile matter content, 78.88% fixed carbon content, 6.259.33 cal / gr calorific value. The use of alaban wood charcoal waste briquettes is able to produce consumption costs efficiency of 60% better than the use of LPG and 70% better than the use of kerosene.

Abstract

Plant Bemban (Donax canniformis) is one of the plants that is often found in the swamp area of South Kalimantan that grows wildly on the roadside and around the home garden. The purpose of this study is to find out how large the bending strength and composite impact is reinforced with bemban fiber with polyester matrix with variations in fiber orientation and alkalization time. The method is done by alkalizing the banana fiber with 4% NaOH solution with a variation of 30 minutes, 60 minutes and 90 minutes. The process of making composites with 3 layers varies the direction of fiber A (0°,45°,90°), B (45°,90°,0°), C (90°,45°,0°) and the method used is how to hand lay up. Broken photos after testing using macro photo observations. The results showed that the specimens with the highest immersion time of 30 minutes for bending with variations A (0°,45°,90°) of 112.24 MPa and the lowest at 60 minutes with variation C (90°,45°,0°) amounting to 12.67 MPa. Price impact (HI) is highest at 60 minutes immersion time with variations A (0°,45°,90°) of 0.0208 joule/mm2 and the lowest at 30 minutes immersion time with variation C (90°,45°,0°) of 0.0115 joules/mm2.

Abstract

Fossil fuels need to be replaced with alternative energy sources such as household waste, used cooking oil. This research utilizes household waste such as used cooking oil as an alternative fuel. In this research biodiesel used waste cooking oil mixed with diesel with a percentage of 50%: 50%, 60%: 40%, 70%: 30%, 80%: 20%, and 90%: 10%. The mixture of waste cooking oil and diesel biodiesel was then made into a 1 mm droplet grain, then a droplet combustion test was carried out. The test results show that the value of ignition delay time increases with increasing percentage of biodiesel used waste cooking oil. The burning rate value increases with the increase in the percentage of used waste cooking oil biodiesel. The temperature value increases with the increasing percentage of biodiesel used waste cooking oil. The maximum fire height value that can be achieved decreases with increasing percentage of used waste cooking oil biodiesel.

Abstract

Throughout the year 2015, PLTU Asam Asam Unit 3 and 4’s Induced draft fans frequently having issues. These issues were affects customer’s elecricity consumption because of load generated from PLTU Asam Asam unit 3 and 4 is was decreased heavily, seldom made the unit shut down for maintenance. This issues was being discussed and investigated to find the source and solutian to fix it. After the investigation, it is found that fly ash who was being carried by flue gas through IDF was stuck to fan’s blade and create unbalance in its rotation. Next modification was applied to fly ash transmitter to make sure its operating continous because it has been stopped for a while. The effect of this modification is quite significant if we compare data from before and after modification, it can be see that derating and shutdown because of IDF problem is fewer than what it was before modification.
