Abstract

The excessive usage of crude oil as the prime source of energy has caused oil deposit depletion, and therefore forced the discovery of alternative and renewable fuel resources. Through extensive studies recently, vegetable oils are believed as one of the most promising solution.  Indonesia is a country with fertile land providing an ideal location for the plantation of oil-bearing plants. One of this potential is found in kemiri sunan (Reutealis trisperma)  oil, which contains about 50% conjugated eleostearatic acid, which can be cyclized to form aromatic compounds. In this preliminary research, kemiri sunan oil was first saponified using KOH creating K-soap solution. Mg and Cr salts were then added to this solution in order to substitute the ion K yielding a mixture of Mg soap and Cr(OH)3 base. DEA (solvent) was added to the basic Mg soap at a 4:1 (b/b) ratio while the Cr(OH)3 acted as a catalyst for the cyclization reaction. The purpose of this research was to explore the hidden potentials in kemiri sunan to synthesize an intermediate product of an aromatic compound by varying temperature (100, 150, 200 °C) and reaction time (2, 3.5 and 5 hours). The cyclization products were tested using FTIR giving absorbance peaks at 771.53 or 779.24 cm-1 which were identified as ortho-disubsituted benzene.

Abstract

Kemiri sunan oil (Reutalis trisperma) is a non-edible vegetable oils which thrives in Indonesia, has α-eleostearic acid that can be processed into aromatic compound through isomerization-cyclizationdisproportionation.The purpose of this research was knowing kemiri sunan oil’s potency for synthesizingaromatic compound and the effects of the reaction’s condition and solvent : feed ratio to the yield of cycliccompound. This research was initiated by testing kemiri sunan oil quality by several tests: acid number,iodine number, and saponification number. Saponification was done using KOH at 60°C ; 3 hours. Then,Mg(NO3)2 was added as substituent for K in base soap and Cr(NO3)3 as a catalyst. Obtained Mg soap wasthen cleaned using aquadest before dried in the oven until its mass was constant at 60°C, then diluted inDiethanolamine. The reaction was held for 2 hours with the variations of temperature and ratio of solvent :feed (w/w). The product was then extracted using toluene in order to gain all of the aromatic compound.Then, the separation of the solvent from the product was done using simple distillation. Cyclic productpresence in the form of ortho-disubstituted benzene was tested qualitatively using FTIR, while thequantitative tests were conducted by Wijs test and aromatic product’s mass calculation.

Abstract

Pemanfaatan abu sawit sebagai biomassa terbarukan dapat dilakukan dengan mengubah kalium yang terkandung di dalamnya menjadi pupuk kalium. Metode analisa untuk mengetahui suatu kandungan berupa mineral dalam suatu bahan tertentu dapat dilakukan dengan analisa melalui alat instrument maupun titrasi. Pada penelitian ini analisa yang dilakukan menggunakan metode titrasi yang selanjutnya dilakukan metode analisa untuk mengetahui kandungan kalium dalam abu sawit, tersebut, abu sawit terlebih dahulu diekstrak dengan merebus abu sawit dengan air dan disaring dengan penyaringan vacuum. Pada penelitian ini digunakan 2 jenis sampel abu, yaitu abu halus dan abu kasar Tandan Kosong Kelapa sawit (TKKS). Abu halus dan abu kasar pada sampel berasal dari daerah Tepian Langsat Kutai Timur. Adapun variabel-variabel yang mempengaruhi kandungan kalium dalam abu kelapa sawit seperti volume aquadest dan waktu perebusan yang bervariasi. Berdasarkan hasil percobaan diperoleh kadar K2CO3 paling tinggi dalam abu sampel halus 1 yaitu sebesar 24.499 % dan pada sampel abu kasar yaitu sebesar 17.8508 %.
