Abstract

Sungai Tohor Village is located in East Tebing Tinggi District, Meranti Islands Regency, Riau Province which has great potential in the field of processing sago plants. In Sungai Tohor Village, there is a Family Income Improvement Business unit (UP2K) which has produced and marketed processed sago palm products in the form of sago sugar. Sago sugar has more advantages compared to other types of sugar besides its relatively cheap price, this sugar also has a low glycemic level making it suitable for people with diabetes. However, high market demand with low production capacity makes it difficult for sago sugar to meet the target. These problems arise because the production time of sago sugar is quite long around 4-5 days, this is due to the traditional drying of sugar because there is no technology that can be used in drying sago sugar effectively and efficiently. The purpose of this activity is to transfer knowledge and assistance in the process of drying the product. The method used is training and practice by the PKM-PI team at the University of Riau regarding the use of drying technology with the Cabinet Dryer Sago Sugar (CADESAR) drying device. Drying technology using CADESAR can improve the quantity and quality of sago sugar products. This technology can reduce production time by using a pressurized hot steam drying system, as one of the drying methods in the modern sugar industry, so that it can increase the amount of production and be more hygienic. The results of the training show that UP2K members can understand and practice knowledge of drying technology well. It is hoped that this will increase the productivity of their sago sugar business.

Abstract

Crop residue open burning contribute the emission of Short lived Climate Forces (SLCF) pollutants thereby threat to global climate change. One of the them is Black carbon (BC). BC is estimated to be the second most potential greenhouse warming agent after Carbon Dioxide (CO2). In Cianjur district, West Java, open burning in the paddy field is common way to eliminate rice residues after harvesting. The main objective of this study was to assess the concentration of BC in ambient air from open burning of rice straw in Cugenang District, as well as assess the effect of the combustion efficiency of the emission BC. Experiment were conducted in District Cugenang at 8 studies sites for irrigated paddy field were carried out for eight varieties paddy (Mekongga, Cintanur, Ciherang, Hibrida, Inpari, Inul, Sarangue, Pandan wangi). The minivol sampler (5 Lpm) were used for PM2.5 sampling and smoke stain reflektometer EEL were used for analysis Black Carbon. BC concentration (µg/m3) in the eight fields burning experiments reported at 25oC, 1 atmosphere. The assess results, show that the net burn smoke of Black Carbon in µg/m3 averaged 85.91±2.26. The highest emissions came from the burning of hybrid varieties with a combustion efficiency of 93.1%. Black Carbon emissions are influenced by the efficiency of combustion, where combustion with flamming phase (> 90%) give higher emissions.

Abstract

Sungai Tohor area, Meranti Islands, Riau, is a producer of sago in Indonesia and has great potential as a producer of sago flour. Sago flour production also produces waste in the form of sago dregs. Sago utilisation in Meranti Regency is still limited, sago stems (tual) are processed in factories (sago refineries) to produce sago flour with a production volume of 450,000 tonnes/year. This sago processing also produces side waste in the form of sago pulp as much as 75-83%. This provides potential in the utilisation of sago pulp as an environmentally friendly alternative energy source. This research aims to develop biopellets from sago pulp as a biomass fuel that can replace fossil fuels. The analysis results show that sago pulp biopellets have a moisture content of 8.22%, ash content of 30.51%, volatile matter of 22.01%, and calorific value of 4,599 cal/gr, which fulfils the SNI 01-6235-2000 standard. The CO and SOx gas emission measurements from the combustion of biopellets were below the threshold set in the Regulation of the Indonesian Minister of Health No. 1077 Year 2011 and SNI 7626-2013. The thermal efficiency of combustion reached 28.15%, indicating that sago pulp biopellets have great potential as an efficient and environmentally friendly biomass fuel, supporting sustainable energy transition in Indonesia.

Abstract

The Assisted Village Service Program was carried out in Maini Darul Aman Village, Tebing Tinggi Barat District, Meranti Islands Regency. This activity aims to assist the community in overcoming the problem of sago pulp waste that has not been optimally utilized. During this time, sago pulp waste is disposed of in a shelter or along the river flow around the sago processing site, which has the potential to pollute the environment. As a solution, this program offers the production of biopellets from sago pulp, which can be used as an alternative to conventional fuels such as firewood and kerosene, and has the potential to become a business opportunity that can improve the family economy. This activity was carried out through several stages, including: socialization to the community about the importance of sago waste management, its impact, and the solutions offered; assistance in processing sago pulp into biomass biopellets; and assistance in using TLUD stoves fueled by sago pulp pellets. The final stage is coaching in marketing management as part of the future development of this program. The Bina Desa program is also integrated with UNRI students' Community Service Program (KKN) activities in 2024, which runs from July to the end of August 2024. Through this program, it is expected that the community can continue to develop the use of biopellets as fuel, both for household needs and industrial scale, such as use in boilers. In addition to protecting the environment, it is hoped that this program can also be a source of income that can improve the welfare of the community.

Abstract

Waste oil empty palm fruit bunches (EFB) one of the renewable energy sources with great potential and is produced approximately 21% of the entire palm oil processing process. Burning EFB briquettes using biomass stoves has a low combustion efficiency, so it has the potential to emit CO. The aim of this research is to determine CO gas emissions resulting from burning empty palm fruit bunch briquettes with variations in the number of holes in the biomass stove and compare them with the quality standards of Minister of Energy and Mineral Resources Regulation No. 047 of 2006. and see how the effect of air hole openings on biomass stoves with empty palm fruit bunch briquettes. In this study, co emission test was conducted using environmental combustion analyzer type 450 and biomass stove performance using water boiling test method. Testing was conducted with variations of air hole openings L1 (3.51 cm2), L2 (7.03 cm2), and L3 (10.55 cm2). The results of CO gas testing obtained by L1, L2 and L3 are 523.54 mg/ Nm3, 425.59 mg/ Nm3, and 351.13 mg / Nm3 and still meet the quality standards of ESDM no. 047 of 2006. Thermal efficiency of briquette stoves obtained in L1, L2 and L3 are 26.51%, 24.28% and 22.28% and for specific consumption rates obtained in L1, L2 and L3 are 3.47 grams/minute, 5.54 grams/minute and 7.17 grams/minute, this result didn’t meet the quality standard of SNI 7926-2013. Based on the results of the study, it was concluded that the smaller the opening of the briquette stove air hole, the more CO emissions produced, the higher the thermal efficiency and the smaller the consumption rate.
