Abstract

The oil palm industry produces solid waste such as oil palm fronds (OPF) and empty fruit bunches (OPEFB), but the utilization of the OPEFB waste is still limited to composting. Even the palm fronds are only left on the farm without being processed. While both types of waste contain a lot of cellulose and can be processed into more economic value. In addition to compost, the two types of waste can be used as pulp and paper. Hence, in this study, the two wastes are processed into the paper with a variety of concentrations of solvents and mixtures. The aim is to determine the effect of solvent concentration in the process of making paper pulp and the effect of the comparison of the mixture of paper pulp with the characteristics of the paper produced. Each material is processed into pulp by the soda process using sodium hydroxide as a solvent. While the solvent concentration used is 20%, 30%, and 40% for materials from OPEFB, while the material from OPF is only mixed with 20% sodium hydroxide solution. Then the pulp, OPEFB pulp with various variations of solvent, mixed pulp with the ratio of OPF pulp and OPEFB pulp of 1: 3; 1: 1; and 3: 1 processed into paper. The resulting paper was analyzed to study folding strength, tear strength, and paper thickness. The results of the study prove that the folding endurance and tear resistance of the paper have smaller in the greater concentration of the solvent. By contrast, the thickness of the paper is greater. Besides, more the mass of OPEFB in the pulp mixture, then the folding endurance and tear resistance of the paper have less, while the thickness is decreasing.

Abstract

Abstrak- Setiap tahunnya produksi kelapa sawit makin meningkat, sehingga akan terjadi peningkatan juga pada limbah kelapa sawit. Limbah kelapa sawit adalah sisa-sisa hasil tanaman kelapa sawit yang tidak termasuk dalam produk utama atau merupakan hasil ikutan dari proses pengolahan kelapa sawit. Limbah padat kelapa sawit dapat berupa tandan kosong, cangkang dan sabut, dimana pada 1 ton kelapa sawit menghasilkan limbah berupa tandan kosong kelapa sawit sebanyak 23% atau 230 kg, limbah cangkang sebanyak 6,5% atau 65 kg, sabut 13% atau 130 kg. Umumnya limbah padat industri kelapa sawit mengandung bahan organik yang tinggi sehingga jika penanganan limbah secara tidak tepat akan mencemari lingkungan. Pada tandan kosong kelapa sawit (TKKS) dapat dimanfaatkan sebagai PLT biomassa, pupuk dan bioetanol. Untuk cangkang kelapa sawit dapat dimanfaatkan sebagai karbon/arang aktif, pembuatan pupuk cair kalium sulfat, pengawet alami tahu, bahan bakar (biomassa), briket. Untuk sabut kelapa sawit dapat dimanfaatkan sebagai bahan penguat sifat mekanik komposit, fiber glass, pengolah limbah cair, pembuatan pulp, media tanaman alternatif, alternatif pengganti solar dan batubara sebagai bahan bakar pembangkit listrik. Masih banyak yang bisa di lakukan untuk pemanfaatan limbah padat kelapa sawit dengan dilakukan penelitian.

Waste of palm oil crops are not included in the main product or a by-product of the processing of palm oil. Solid waste can be either oil palm empty fruit bunches, shells and fiber (coir), which on 1 ton of palm oil generates waste in the form of empty fruit bunches of oil pam as much as 23% or 230 kg, the waste shell as much as 6.5% or 65 kg, coir (fiber) 13% or 130 kg. Generally palm oil industrial solid waste contain organic matter so that if the improper handling of waste will pollute the environment. In the oil palm empty fruit bunches (EFB) PLT can be used as biomass, manure and bioethanol. For palm kernel shells can be used as a carbon/charcoal, liquid potassium sulphate fertilizer production, and natural preservatives. To coir (fiber) palm oil can be used as a reinforcing material for the mechanical properties of the composite, fiber glass, liquid waste processing, manufacture of pulp, media alternative crops, alternative to diesel and coal as fuel for electricity generation. There is still much that can be done for solid waste utilization of palm oil by doing a research.Keywords: solid waste of palm oil, EFB, palm kernel shells, fiber of palm oil

Abstract

Abstract- Terminalia catappa Linn. (ketapang) is a coastal tree with a widespread area. Its derived from the tropics of India, and spread to Southeast Asia, Northern Australia and Polynesia in the Pacific Ocean. This study aims to determine the effect of maceration time on the density of the species, yield, and % FFA from oil of ketapang. The research procedure is done by soaking ketapang seed powder wrapped with filter paper into a chemical glass containing 500 mL of n-Hexane solvent. Then the solvent which has been mixed with oil, separated by distillation. Variables used in this research is the variation of immersion time in the unit of day. The results of the research are 25-31 mL of oil volume, yield percentage of 0.44-0.52, density of 0.84-0.88 g / mL, 28-35% percentage of FFA. Ketapang oil obtained a lot of fatty acids that can be used as raw materials for making biodiesel but it needs to be pre-esterification first to reduce levels of FFA up to 2%. Keywords:      FFA, Ketapang Oil, Maseration, Yield

Abstract

Abstrak- Produksi sampah plastik meningkat setiap hari dan dapat merusak lingkungan karena plastik sulit terurai. Oleh karena itu mengurangi penggunaan plastik atau mengganti bahan baku plastik adalah salah satu solusi untuk masalah lingkungan. Selulosa adalah salah satu bahan pembentuk plastik dan salah satu sumber selulosa adalah tandan kosong kelapa sawit. Selulosa diekstraksi dari limbah tandan buah kosong menggunakan metode delignifikasi dengan larutan NaOH 17,5% selama 3 jam pada suhu 90-95˚C. Sintesis bioplastik diproses dengan selulosa, pati dan gliserol. Metode sintesis yang digunakan adalah pemanasan selama 1 jam pada suhu 80-90˚C. Variabel yang dianalisis adalah variasi selulosa dan massa pati 0,4 g dan 0,8 g; 0,5 g dan 0,7 g; 0,6 g dan 0,6 g; 0,7 g dan 0,5 g; dan 0,8 g dan 0,4 g. Tes bioplastik yang dilakukan meliputi uji ketahanan air, uji kepadatan, dan uji biodegradasi. Hasil yang paling optimal dalam uji ketahanan air adalah 29,17%, uji kepadatan 0,7273 g mL, dan uji biodegradasi adalah 19,58%.  Keywords :  tandan kosong kelapa sawit, selulosa, delignifikasi, sintesa, bioplastik.
