PENGELOLAAN SAMPAH MENJADI ENERGI BERBASIS TEMPAT OLAH SAMPAH SETEMPAT (TOSS) DI KOTA TANGERANG SELATAN

One of the serious problems faced by the South Tangerang City Government today is waste management. According to the Tangsel City DKPP, the volume of waste is 800 tons or around 3,600 cubic meters per day. Until now, the community's waste management system is carried out with a 3R (Reduce-Reuse-Recycle) system in 49 TPS-3Rs that are spread out in every district in the South Tangerang area. The problem at this time is that some of the TPS-3R have not yet operated optimally, so the volume of waste transported to the Cipeacang TPA is still high. Management of waste into energy based on Local Waste Management Sites (TOSS) through a collaboration between STT-PLN and ITI was developed to process waste that produces pellets as an energy raw material that can be used for cooking (special stoves), processing it in a gasifier machine to get gas (syngas) ) which can be consumed by household or electricity generator raw materials. At present trials of the application of TOSS are conducted in several TPS-3Rs in Setu and Pamulang Districts. The series of activities carried out include training and mentoring processing of waste (various types of waste) into pellets, design, manufacture and testing of pellet-fueled stoves, as well as the design, manufacture and testing of gasifier machines to produce gas (syngas) which is distributed to households. The implementation of a TOSS-based waste management system is expected to be able to solve the waste problem in South Tangerang City and get added value through the conversion of waste into energy that can be utilized by the community.Keywords: garbage, TPS-3R, local waste management (TOSS), waste pellets, South Tangerang Cit

THE EFFECT OF MILLING TIME AND PERCENTAGE OF DISPERSING AGENT ON THE CHARACTERISTIC OF SOLVENT-BASED BLACK PAINT FROM CARBON BLACK PIGMENT

THE EFFECT OF MILLING TIME AND PERCENTAGE OF DISPERSING AGENT ON THE CHARACTERISTIC OF SOLVENT-BASED BLACK PAINT FROM CARBON BLACK PIGMEN. The need for black paint made from carbon black pigment increasing year by year especially in the automotive world. The production of black paint is performed by milling the resin, pigment, additive/dispersing agent, and solvent. In the manufacturing process, it takes a relatively long time with precise dispersing agent composition toward pigment to get the product with blackness/solid black according to the expected quality. This work aims to study the role of the milling time of carbon black fw 200 beads on a 3 liter ball mill and the percentage of dispersing agents on paint color quality, especially blackness. The variations in milling time were 36, 48, and 60 hours and the weight percentage of dispersing agent toward pigment were 80%, 100%, and 120%. The optimum results obtained are at the milling time of 48 hours and on the percentage of dispersing agent of 120% with the product characteristics fulfills the requirement namely: 10 μm of particle fineness, 111.5 krebs unit of viscosity, 36.97% of solid content, 0.9839 gr/cc of specific gravity with desirable solid black color

ANALISIS MODIFIKASI DESAIN REAKTOR PADA RANCANG BANGUN ALAT PIROLISIS DAN PENGUJIAN NILAI KALOR UNTUK PLASTIK PP DAN ABS

The increasing use of plastic results in a rise in the volume of waste each year and has an impact on the environment. Pyrolysis is a method for recycling plastic waste into fuel oil. Improvements in pyrolysis design and techniques continue to be made to obtain better performance and optimal results. In this study, we compare the rate of increase in heat and volume of oil produced from two pyrolysis device designs. The alpha version is the previous version of the pyrolysis apparatus with a flat plate roof reactor and without the addition of an insulator on the tube wall. While the beta version is a modification of the alpha version with a conical roof reactor with the addition of calk material on the tube wall. Modification of the pyrolysis apparatus was also carried out in the condensation section. The beta version of the pyrolysis device shows better performance, where the reactor temperature reaches 250 ⁰C, while the alpha version, which is the previous version, reaches a maximum temperature of 220 ⁰C in a longer time. The volume of oil produced by the beta version is 0.11 mL/gram of polypropylene plastic, whereas the alpha version produced only 0.01 mL/gram for the same material. The test results for the calorific value of polypropylene (PP) plastic waste were 43.838 MJ/kg, while for acrylonitrile butadiene styrene (ABS) it was 44.772 MJ/kg

Incubators for Household-Scale Yoghurt Production in Improving Production Process in Kuningan District

The quality of yoghurt produced in District of Cipari, Cigugur Kuningan Regency failed to meet the required standard despite the fact that socialization of yoghurt GMP program, facilitation and delivery of inkubator for yoghurt production had been implemented. Therefore, this study reported the performance of the incubators which had been produced and granted to two cooperatives in the District of Cipari, Kuningan, namely Laras Ati and Lembah Kamoning. The method used was to directly test the incubators for the production of yoghurt in a laboratory Institut Teknologi Indonesia and in Kuningan. Five litres of cow's milk that had been heated to a temperature of 90° C for 15 minutes and cooled down to a temperature of 40° C were directly inoculated with a 10% volume of fresh commercial yoghurt starter, culture consisting of Lactobacillus acidophilus, Streptococcus thermophilus and Bifidobacterium. The measured parameters were incubator temperature stability, product's pH value, total acid and organoleptic of product. The results showed that the performance of the two incubators were in good condition. It was proved by stable temperature in the range of 44.1±0.6°C during evaluation within 7 hours of incubation. During fermentation, pH of the product has decreased and reached a pH value of 4.6 ± 0:02 within 7 hours of incubation, total acid reached 0.84±0.052%. The organoleptic product of yoghurt showed the percentage of product acceptance reached 85%, 83%, 86% and 82% in colour/appearance, texture, odour/flavour and taste respectively. The two delivered incubators met the required standard, thereby making the household-scale production process of yoghurt safe for public consumption. Yoghurt ready for sale and kept at the room temperature remains fresh and does not suffer damage because the packaging is not inflated as before.Yoghurt that is ready to be sold and even kept at room temperature remains fresh and does not suffer damage ie. the packaging is not inflated as before
