Abstract

The research about utilization ash of coconut husk as source of base catalyst in aplication for reaction of transesterification from Jatropha curcas oil has been researched. Content of base compound in coconut husk ash was analyzed by AAS and acidy alkalimetry. The base catalyst was extracted using methanol, for transesterification reaction of Jatropha curcas oil. This method of biodiesel production by transesterification process used coconut husk ash catalyst by weight variation as much as 2%, 4%, 6%, 8% and 10% (w/w). Analysis of the quality of biodiesel is done with quality parameters acid number, iodine number, density, viscosity and water content in accordance with SNI 04-7182-2006 standards. The result of the research showed that potassium concentration as carbonat salt in the ash of coconut husk was 17,4% (w/w) and the conversion of biodiesel obtained from each catalyst in a row is 43,62%; 78,45%; 76,22%; 75,69% and 63,27% (w/w). Biodiesel optimum results obtained with the addition of the catalyst are 4% with density values of 0.86 (g / mL), the viscosity value of 3.23 (cSt), the value of water content 0.0352%, 0.12 acid number (mg KOH / g) and iodine number of 8.23 (g I2 / 100 g).The research about utilization ash of coconut husk as source of base catalyst in aplication for reaction of transesterification from Jatropha curcas oil has been researched.

L) telah dilakukan. Karakterisasi kadar basa dalam sabut kelapa dilakukan dengan AAS dan alkalinitas. Katalis basa diperoleh dengan pengadukan abu sabut kelapa dalam metanol dan selanjutnya digunakan untuk reaksi transesterifikasi minyak biji jarak pagar (Jatropha curcas. L). Metode pembuatan biodiesel ini dengan transesterifikasi menggunakan katalis abu sabut kelapa dengan variasi berat sebanyak 2%, 4%, 5%, 6%, 8% dan 10% (b/b). Analisis kualitas dari biodiesel dilakukan dengan parameter mutu bilangan asam, bilangan iod, densitas, viskositas dan kadar air sesuai dengan standar SNI 04-7182-2006. Hasil penelitian menunjukkan bahwa kadar kalium dalam bentuk kalium karbonat dalam abu sabut kelapa sebesar 17,4% (b/b) dan konversi biodiesel yang diperoleh dari masing masing katalis berturut-turut adalah 43,62%; 78,45%; 76,22%; 75,69% dan 63,27% (b/b). Hasil optimum biodiesel diperoleh dengan penambahan katalis 4% dengan nilai densitas 0,86 (g/mL), nilai viskositas 3,23 (cSt), nilai kadar air 0,0352%, bilangan asam 0,12 (mg KOH/g) dan bilangan iod sebesar 8,23 (g I2/100 g). Kata kunci :    Abu sabut kelapa, biodiesel, transesterifikasi, minyak biji jarak pagar(Jatropha curcas.

Abstract

The effect of the addition of corn starch adhesive and bentonite to waste coconut shell charcoal briquettes research are purposed to determine the effect of corn starch adhesive and bentonite waste coconut shell charcoal briquette with the variation of the concentration of corn starch and bentonite so it can produce briquettes that qualify as fuel. Design research method using the addition of corn starch and bentonite 3:2; 2,5:2,5 and 2:3 (w /w) g by using coconut shell charcoal waste 5kg with descriptive data analysis, while treatment has 5 (five) times repetation. The results showed that the range: 4.20 to 4.40% moisture content, ash 9.24 to 9.80%, from 0.63 to 0.68 density type g/m³, the missing part on the heating temperature of 950 °C 13,77 to 13.92% and the calorific value of 6728.15 to 6729.61 cal/g. Briquettes obtained can be used as an alternative fuel, using 700 g briquettes can cooked 5 (five) liters water, and it’s takes 45-56 minutes. The analysis showed that the best treatment is using corn starch and bentonite is 3:2, which produces a high enough caloric value is equal to 6729.61 cal/g.ABSTRAKPenelitian pengaruh penambahan perekat tepung sagu dan bentonit terhadap briket limbah arang tempurung kelapa dilakukan dengan tujuan untuk mengetahui pengaruh perekat tepung sagu dan bentonit briket limbah arang tempurung kelapa dengan variasi konsentrasi tepung sagu dan bentonit sehingga dihasilkan briket yang memenuhi syarat sebagai bahan bakar. Metode rancangan penelitian adalah penambahan tepung sagu dan bentonit 3:2; 2,5:2,5 dan 2:3 (b/b) gram  dengan menggunakan limbah arang tempurung kelapa sebanyak 5 kg dengan data dianalisis secara deskriptif, sedangkan ulangan dilakukan sebanyak 5 (lima) kali. Hasil penelitian menunjukkan kisaran: kadar air 4,20-4,40%, abu 9,24-9,80%, kerapatan jenis 0,63-0,68 g/m³, bagian yang hilang pada pemanasan suhu 950°C 13,77-13,92% dan  nilai kalori 6728,15-6729,61 kal/g.  Briket yang diperoleh dapat digunakan sebagai bahan bakar alternatif, dengan menggunakan 700 gr briket pemasakan air 5 (lima) liter  memerlukan waktu 45-56 menit. Perlakuan terbaik diperoleh dengan perbandingan tepung sagu dan bentonit yaitu 3:2 yang menghasilkan nilai kalori yang cukup tinggi adalah sebesar 6729,61 kal/g. Kata kunci : Tempurung kelapa,limbah arang, tepung sagu, bentonit, briket
