This study is a research on water hyacinth-based briquettes which shows the calorific value of each form of briquettes. The purpose of this study was to analyze the quality of water hyacinth briquettes with variations in pressure and pellet geometry. The quality analyzed includes moisture content and calorific value. The method of making briquettes starts from charcoal, pounding, then mixing with tapioca starch adhesive. The composition of the mixture used is 90% water hyacinth charcoal with 10% tapioca starch adhesive. 4 geometric variations are used, namely, solid box, hollow box, solid tube and hollow tube with 3 pressure variations, namely, 10 PSI, 20 PSI and 30 PSI. Test results and analysis,briquettes at a pressure of 20 PSI produces a calorific value range of 91.15 - 150.14 cal / gram. The resulting calorific value is higher than the briquettes at a pressure of 10 PSI and 30 PSI with a heating value range of 93.84 - 148.79 cal / gram and 89.81 - 135.39 cal / gram. Hollow briquettes produce a calorific value range of 107.24 - 150.14 cal / gram higher than solid geometric briquettes which produce a heating value range of 89.81 - 148.79 cal / gram. So that the contribution of the results of this research is that the community makes briquettes with shape and pressure with good results shown in this study.

Lumpur IPAL pada Kawasan Industri sampai saat ini belum dapat dimanfaatkan dengan baik, pemanfaatan lumpur IPAL menjadi briket merupakan salah satu upaya untuk mengatasi permasalahan limbah lumpur IPAL. Tujuan penelitian ini adalah mengetahui lumpur IPAL dengan campuran serbuk gergaji kayu dapat dijadikan bahan bakar alternatif berupa briket, mengetahui pengaruh variasi lumpur IPAL dan serbuk gergaji kayu terhadap mutu briket berupa kadar abu, nilai kalor, kadar air , dan mengetahui komposisi terbaik antara lumpur IPAL dan serbuk gergaji kayu untuk menghasilkan nilai kalor optimum pada briket. Metodologi penelitian meliputi pengeringan bahan, karbonisasi bahan, penghalusan dan penyaringan bahan 20 mesh (841 µm), 40 mesh (420µm), dan 60 mesh (250 µm), pencetakan dan pengepresan briket, serta pengeringan briket. Selanjutnya dilakukan uji mutu briket, hasil analisis pada briket terbaik terdapat pada perbandingan 20 : 80 dengan menggunakan ayakan 60 mesh, memiliki nilai kalor 4366,8 kal/g, kadar air 1,26% dan kadar abu 1,32%. Nilai kalor pada briket masih belum memenuhi baku mutu dari SNI 4931 Tahun 2010, Minimnya nilai kalor yang dihasilkan bisa juga karena variabel perlakuan, dengan perbandingan yang dilakukan terhadap lumpur dan serbuk gergaji serta menggunakan ukuran ayakan yang berbeda. Kata Kunci : briket, lumpur IPAL, serbuk gergaji kayu. IPAL sludge in the Ngoro Persada Industry has yet to be utilized properly, utilizing IPAL sludge into briquettes is one of the efforts to solve this problem. The aim of this research was to determine the IPAL sludge with a mixture of wood sawdust can be used as an alternative fuel in the form of briquettes, to determine the effect of variations in IPAL sludge and wood sawdust on the quality of briquettes in the form of heat value, ash content and moisture content as well as knowing the best composition between IPAL sludge and wood sawdust to produce briquettes with the best heating value. The research methodology included material drying, carbonization of materials, refining and filtering of 20 mesh (841 μm), 40 mesh (420μm), and 60 mesh (250 μm), printing and pressing briquettes, and briquette drying. Furthermore, briquette quality testing was conducted, the results showed that the best briquettes were at a ratio of 20: 80 using 60 mesh sleve, having a heating value of 4366.8 cal / g, 1.26% moisture content and 1.32% ash content. The calorific value of briquettes still does not meet the quality standards of SNI 4931 of 2010, the lack of heat value produced can also be due to treatment variables, with the comparison carried out on sludge and wood sawdust and using different sieve sizes. Keywords: briquettes, IPAL sludge, wood sawdust.

The objective of this research was to analyse organic fertilizer pellets from water hyacinth and oil palm empty fruit bunch (OPEFB) that have not been widely used in South Kalimantan. The variable of the research was the ratio of water hyacinth and OPEFB: 25%:75%, 50%:50%, and 75%:25%. The fertilizer was produced by heating the materials at 350oC, and then composting the materials using effective microorgnism 4 (EM4), and then mold into pellet shape. The results showed that the drying, heating, and composting process could increase nitrogen and phosphor content. Nitrogen in water hyacinth increased from 0.06% to 2.18%, while its increased from 0.18% to 2.49% in OPEFB. Phosphor in water hyacinth increased from 3.42% to 6.89%, while its increased from 1.95% to 4.70% in OPEFB. The quality of organic fertilizer pellet was evaluated according to Permentan No.70-2011. The result showed that the content of C-organic, macro nutrients, micro nutrients, heavy metals, Escherichia coli, Salmonella sp., moisture content, pH, and residue met the requirements. The organic fertilizer contained the highest nutrient made from 50 % water hyacinth and 50% OPEFB.Keywords: organic fertilizer pellets, oil palm empty fruit bunch, water hyacinth

Modernization in water technology plays a major role in ensuring a clean, safe, and feasible supply of drinking water. Enhancing performance in terms of price and quality, flow ability of the plant, sustainable development; integrated membrane processes have been developed. The most crucial issues found in RO applications such as concentration polarization and membranes fouling are reduced by using this integration of membranes. Conventional reverse osmosis filtration has sand and coke filters as pre filters. In this work these pre filters have been replaced by ultra-filtration which ensures undoubtedly the best quality of water despite the quality of feed with low power consumption and chemicals. These integrated systems are the better thing for complete elimination of microorganism and water contaminants in their category of selection. The present work also contributes on water quality analysis for brackish water using both the above desalination membrane technology. This integrated system can be remotely monitored and self-adapted model-based control.

There is a great potential for bamboo to be applied as a biofuel for the future due to its good fuel properties with low alkali index and fast growth rate. Torrefaction treatment can increase the fuel quality of biomass in terms of the calorific value, energy density and storability. The aim of this research was to explore the effect of torrefaction temperature and reaction time on the fuel properties of B. vulgaris and G. scorthecinii. The bamboos were treated at various torrefaction temperatures (200, 250 and 300˚C) and reaction time (15, 30, 45 mins). In overall, the highest higher heating value was obtained from bamboos torrefied at 300ºC for 45 mins. In general, the temperature used in torrefaction has a relatively stronger effect on the higher heating value while the impact of the residence time was considerably lesser.

Study on the purification and quality test of used cooking oil with turmeric has been done. This study aims to determine the quality of cooking oil after purified turmeric. The quality parameters of oil studied were the moisture content, free fatty acids (FFA), and peroxide. The methods used for determination of these parameters were gravimetry for moisture content, acid-base titration for free fatty acids, and iodometric for peroxide. The test results for water from 0.6% to 0.4% free fatty acid from 1.2% to 0.2%, and peroxide levels before and after purification were successively from and 6 meq/g to 4 meq/g, respectively. Only free fatty acids of all three parameters met the requirement of SNI.
