The effectiveness of the absorption of activated rice husk and hazelnut shells on the purification of used cooking oil has been carried out. The aim is to determine the absorption capacity of the active charcoal of rice husk and hazelnut shells to purify used cooking oil. After being physically activated, activated charcoal from rice husk and pecan shells is applied to the purification of used cooking oil. The results show that the quality of hazelnut shell charcoal is better than rice husk after it is applied to purifying used cooking oil.

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.

Driven by the need of growing to a more sustainable and environmentally friendly future, this research is started by mixing in-house produced biorenewable polymers (BP) from waste cooking oil with the standard low density polyethylene (LDPE) and high density polyethylene (HDPE) via melt-mixing at low ratios. These mixtures are then compounded via injection molding to produce tensile samples. By using the quality of individual compounds injected, the parameters obtained for all ratios of LDPE/BP were the same with neat LDPE whereas some adjustments were required for the HDPE/BP compounds. The corresponding mechanical behaviors of each ratio were also examined and the results showed that both tensile strength and strain of the LDPE/BP were better than neat LDPE. On the other hand, increasing the BP content in HDPE/BP will increase the toughness of the compound if compared to neat HDPE. Therefore, not only does the presence of BP provide renewable properties, but it also improves the mechanical properties. Moreover, the processing temperature and composition of BP will both influence the quality and mechanical behavior of the product made. Thus, this study may aid any intention on processing these in-house produced polymers by injection molding.

ABSTRAK Briket bioarang merupakan salah satu bahan bakar yang berasal dari biomassa. Biomassa yang digunakan dalam penelitian ini adalah tempurung kelapa dan sekam padi. Penelitian ini bertujuan untuk mengetahui pengaruh variasi komposisi sekam padi dan variasi perekat terhadap parameter fisis briket tempurung kelapa. Hasil penelitian ini menunjukkan nilai densitas, nilai kadar air, nilai porositas dan nilai kadar abu, secara berturut-turut berkisar antara (0.69  - 1.12 ), (3,33% - 7,57%.), (16,66% - 31,88%.), (38,46% - 66,66%.). Analisis menunjukkan bahwa secara umum, komposisi sekam padi berbanding terbalik dengan nilai densitas, nilai kadar air dan nilai kadar abu briket dan berbanding lurus dengan nilai porositas briket. Berdasarkan nilai densitas, nilai kadar air, dan nilai kadar abu briket, dapat disimpulkan bahwa dalam penelitian ini briket dengan komposisi 40% tempurung kelapa dan 60% sekam padi memiliki kualitas yang lebih baik dibandingkan dengan komposisi lainnya. Kata Kunci : Briket, Tempurung kelapa, Sekam padi, Densitas, Kadar air, Porositas dan Kadar abu. ABSTRACT Bio-briquette is one of the fuels that comes from biomass. The biomass used in this research is coconut shell and rice husk. The aims of this research are to know the influence of variation of rice husk composition and thickness variation on physical parameters of shell briquettes. The results of this study indicate that the density, moisture value, porosity and ash values, respectively ranged between (0.69  - 1.12 ), (3,33% - 7,57%.), (16,66% - 31,88%.), (38,46% - 66,66%.). The analysis showed that in general, the composittion of rice husk is inversely proportional to density, moisture value and briquette ash value, otherwise the composition of rice husk is directly proportional briquette porosity value. Based on density value, mositure value and ash value it can be concluded that in this research the quality  of briquettes with composition 40% coconut shell and 60% rice husk is better than the other compositions.

Oil Adsorption

Used cooking oil can be used as raw material for biodiesel, but the levels of free fatty acids (Free Fatty Acid, FFA) is quite high. It is necessary for pretreatment in the form of the adsorption process to reduce levels of FFA. This study aims to determine the optimal conditions of adsorption process and determine the quality of biodiesel produced from adsorption processes and transesterification. Natural zeolites are used as adsorbents activated beforehand using ammonium chloride, calcined and heated to obtain H-zeolite. Furthermore, the adsorption process optimization includes the time, the adsorbent concentration, temperature and particle size. The oil that is already in the adsorption catalyst is reacted with methanol and KOH to obtain biodiesel. The optimum adsorption conditions obtained at the time of 90 minutes, the concentration of H-zeolite 12%, temperature 90 ° C, and a particle size of 0.2 mm that can lower FFA levels from 3.2% to 1.1%. Biodiesel produced meets the quality requirements of SNI 04-7182-2006 with a water content of 0.02%, a density of 857.60 kg / m3, the acid value of 0.29 mg-KOH / g, iodine number 15.71, saponification 168 , 02 and cetane index of 75.62. Compounds contained in biodiesel are methyl 9-octadecanoic (49.45%), methyl heksadekanoat (20.79%), and methyl 9,12oktaekanoat 9.12 (18.87%).
