Abstract

Penelitian ini bertujuan untuk menjadikan serat tandan kosong kelapa sawit menjadi bahan “Penguat dan penambah daya serap air” dalam pembuatan spons selulosa. Analisa dilakukan terhadap kemampuan penyerapan air, biodegrabilitas, dan kuat tarik. Hasil penelitian, menunjukkan bahwa pada hasil analisa penyerapan air diperoleh kadar penyerapan air pada masing-masing sampel berkisar antara 4,5 – 6 kali berat kering spons selulosa, kerapatan spons selulosa mempengaruhi kadar penyerapan airnya yaitu semakin besar jumlah Na2SO4.10H2O yang digunakan, maka semakin berkurang kerapatan spons dengan demikian maka kadar penyerapan airnya semakin kecil. Jumlah serat TKS juga mempengaruhi kadar penyerapan air, semakin banyak serat yang digunakan ,maka semakin besar kadar penyerapan airnya. Pada hasil analisa biodegrabilitas menunjukkan bahwa spons selulosa yang ditanam ke dalam tanah selama 1 minggu mulai terdegradabel (terurai), termakan oleh mikroorganisme. Pada minggu keempat spons selulosa telah habis semua dimakan oleh mikroorganisme. Sedangkan pada spons sintetik, tidak ada perubahan yang terjadi setelah 4 minggu (tidak terdegradabel). Dari hasil analisa kuat tarik, menunjukkan bahwa semakin besar jumlah serat TKS yang digunakan, maka semakin besar pula kuat tariknya.Kata kunci: serat tandan kosong sawit, selulosa, selulosa xantat, spon selulosa.

Abstract

In this research, zeolites were used to increase the levels of ethanol distillation process results of laboratory Department of Chemical Engineering Politeknik Negeri Lhokseumawe. Ethanol yield after distillation process only reaches 20.66%, to increase the concentration of ethanol used advanced treatment is by the adsorption method. The results were obtained optimum ethanol concentration, ie 38.67% with a contact time of 8 hours and 80 mesh size. the refractive index and density of 1.33960 and 0.798. bioethanol with 3 g of limestone can eliminate moisture content up to 29.36%; the activation treatment adsorption process of bioethanol with adsorbent zeolite, limestone, and limestone following the zeolite with Freundlich isotherm with adsorption capacity of each 4.5 mg / g; 5.7 mg / g; and 6.4 mg / g.

Abstract

Temurui leaves or curry leaves (Murraya Koenigii) are widely available in Aceh, this plant is one of the wild plants, but unfortunately it is only used as a cooking spice by the community. In this study, the temurui leaves were distilled to extract the essential oil, thereby increasing the economic value of the temurui leaves. The tests carried out to determine the criteria for the essential oil of temurui leaves (curry leaves) were yield, density, refractive index and GC-MS analysis. The temurui leaf distillation is operated by the steam boiler distillation method and uses leaves that have been aerated, using variations in drying 0, 1, 2, and 3 days and distillation time variations of 4, 5, 6, and 7 hours, with a distillation time of 7 hours. hours and 1 day of drying to get the best yield and distillate with a value of 21.5 ml. Based on the research conducted, it can be concluded that the longer drying time can affect the yield obtained, and the longer the refining time, the more oil distillate is obtained. The results of GC-MS obtained Caryophyllene of 76.33% which has a function as an antibacterial, and -Humulene 18.49% which has a function as a prevention of cancer cell growth, with the highest density of 0.8928 and the result of a refractive index of 1.5128. it has fulfilled the SNI for teumuri leaf essential oil. Keywords: Murraya Koenigii, Temurui Leaves, Distillation, Curry Leaves.
