Palm oil mill boiler ash is one of the substances that can be used as an adsorbent. The adsorbent can absorb certain components of a fluid phase, which before being applied needs to be activated using chemicals so that the effectiveness of the absorption is increasing. The use of adsorbents in CPO is quite effective in maintaining its quality. Several previous studies have studied the application of adsorbents in maintaining the quality of CPO. The purpose of the study was to utilize palm oil mill boiler ash as an adsorbent of several types of activators and to determine the effect of effective activator types in application to the quality of CPO oil. This study used a non-factorial completely randomized design with adsorbent activation treatment using H3PO4 and NaCl with a concentration of 10% and soaked for 24 hours. There are 3 parameters observed in the adsorbent application to CPO, namely free fatty acids, water content, and dirt content. The results showed that the adsorbent activated with H3PO4 was an effective adsorbent with a decrease in its free fatty acids up to 0.43%, water content decreased to 0.07%, but an increase in CPO impurities content of 0.24%. While the adsorbent activated using NaCl showed free fatty acids 0.22%, water content decreased by 0.03% and dirt content also increased by 0.24%. Keywords:   adsorbent activator, crude palm oil, boiler ash, H3po4, Nacl

Luas perkebunan kelapa sawit di Indonesia pada tahun 2014 mencapai 10 juta Ha. Pertumbuhan yang pesat diikuti dengan produksi crude palm oil (CPO) dan palm karnel oil (PKO) yang juga meningkat, sekaligus produk sampingan berupa limbah. Salah satu limbah pabrik kelapa sawit yang jumlahnya besar adalah tandan kosong kelapa sawit (TKKS). Tandan kosong kelapa sawit merupakan limbah organik yang berpotensi dimanfaatkan dibidang pertanian. Akan tetapi, TKKS memiliki nilai C/N yang cukup tinggi, akibatnya sukar dan lama untuk terdekomposisi. Salah satu cara pemanfaatan TKKS adalah dengan dilakukan pengomposan dengan pengkayaan urea. Diharapkan dengan perlakuan tersebut TKKS akan cepat terdekomposisi dan dapat segera dimanfaatkan oleh tanaman. Penelitian ini bertujuan untuk (1) mengetahui pengaruh pemberian urea terhadap pengomposan TKKS dan (2) mengetahui pengaruh peningkatan dosis urea terhadap kualitas kompos TKKS. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) faktor tunggal dengan 5 perlakuan, yaitu U1 (urea 0 g setara dengan nilai C/N=), U2 (urea 30,9 g setara dengan nilai C/N=), U3 (urea 79,3 g setara dengan nilai C/N=), U4 (urea 176,1 g setara dengan nilai C/N=) dan U5 (urea 466,3 g setara dengan C/N = ) dan 9 ulangan, sehingga diperoleh 45 satuan percobaan. Hasil penelitian menunjukan bahwa pemberian urea berpengaruh sangat nyata terhadap susut bobot, kadar air, nilai pH kompos, C-organik, N-total, P-tersedia, dan nilai C/N, selain itu pemberian urea mengakibatkan terjadi perubahan tekstur dan warna pada kompos TKKS. Pemberian dosis urea 466,3 g mampu meningkatkan kandungan N-total, serta menurunkan nilai C/N dan nilai pH kompos. Pemberian dosis urea 79,3 g atau setara dengan C/N = mampu meningkatkan kandungan P-tersedia dan kadar air, menurunkan susut bobot dan kandungan C-organik, serta menunjukan perubahan tekstur dan warna yang lebih baik.

ABSTRACT Plukenetia volubilis is a species native to the Amazonia and has economic potential due to the high contents of polyunsaturated fatty acids and vitamins of the seeds; however, information about production of seedlings in nursery is scarce. Factors that contribute to fast emergence and generation of vigorous seedlings are desirable for plant production in the nursery. Therefore, this study aimed to identify the most favorable substrate and seed position for the production of P. volubilis seedlings. The seeds were sown in the following four positions: hilum facing up, hilum facing down, seed lying on its cotyledon suture, and seed lying flat on one of its cotyledon faces. The substrates were sand, vermiculite and commercial substrate. Treatments were distributed according to a completely randomized design in a 4 × 3 factorial arrangement (seed position and substrate) with three replicates of 25 seeds each. The following variables were evaluated: emergence percentage; first count of seedlings; number, width and length of leaves; plant height; stem diameter; dry matter of shoots and roots. It was concluded that the production of P. volubilis seedlings is not affected by either substrate or seed position at sowing. The substrates most favorable to the quality of P. volubilis seedlings were the commercial substrate and vermiculite, always for the positions of seed lying on its cotyledon suture, with faces parallel to tube walls, and seed lying flat on one of its faces.

Quality is the overall characteristics and characteristics of a product or service whose ability to satisfy needs, both expressed and implied (Irwan & Haryono, 2015). In this era of increasingly competitive industrialization, every business person who wants to win the competition in the industrial world will pay full attention to quality. QCC is a new concept to improve the quality and productivity of industrial/service work. It is evident that one of the success factors of industrialization in Japan is the effective implementation of QCC. In this research journal, the quality of crude palm oil (CPO) levels is decreasing. There are 3 types of defects, namely levels of FFA (Free Fatty Acids), levels of Moisture (Water) and levels of Dirt (Stool). Of these three, the most dominant are FFA levels and Moisture levels. Free fatty acid content (FFA) of 158 samples tested contained 150 samples of free fatty acids (FFA) which were outside the company standard. Then followed by moisture content with a total defect of 45 samples from 158 test samples. At the level of dirt (Dirt) there are absolutely no samples that are outside the company's standards.

Secara alami air memang sudah ada pada minyak. Pada tahap penetralan untuk pemurnian minyak kelapa sawit, air juga terbentuk akibat reaksi antara kaustik soda dengan asam lemak bebas. Tujuan penelitian ini adalah untuk mengetahui pengaruh kadar air pada pada proses pemucatan minyak kelapa sawit terhadap warna minyak dan terhadap asam lemak bebas. Penelitian dilakukan pada temperature operasi 70 °C dengan menggunakan pompa vakum (30-40 cmHg). Bahan pemucat yang digunakan tanah bentonite sebanyak 1,5% dari berat total keseluruhan minyak. Dilakukan dengan bantuan pengaduk dalam membantu penyerapan zat warna selama 30 menit oleh tanah bentonite. Hasil penelitian menunjukkan bahwa Kandungan air dalam minyak sangat berpengaruh terhadap warna minyak yang dihasilkan pada proses pemucatan. Bertambahnya kadar air, maka sangat berpengaruh terhadap warna minyak . Pengaruh kadar air juga terlihat terhadap asam lemak bebas (bilangan asam). Semakin tinggi kadar air minyak maka semakin besar harga bilangan asam minyak .   Water naturally exists in oil. In the neutralization stage for refining palm oil, water is also formed due to the reaction between caustic soda and free fatty acids. The purpose of this study was to determine the effect of water content on the bleaching process of palm oil on the color of oil and on free fatty acids. This study was carried out at an operating temperature of 70°C using a vacuum pump (30 - 40 cmHg). The bleaching material used by bentonite soil was 1.5% of the total weight of the oil. It was carried out with the help of a stirrer to help the dye absorption for 30 minutes by bentonite soil. The results showed that the water content in the oil greatly affected the color of the oil produced in the bleaching process. The increase of the water content greatly affected the oil color. The effect of water content was also seen on free fatty acids (acid numbers). The higher the water content of the oil, the greater the number of oil acid.

The purpose of this paper is to prove that waste palm oil industry (POME) can be used as raw material (source of energy) for biodiesel. In the production process, palm oil mill produced large amounts of waste. The provision of a shelter pond system is a temporary solution from palm oil mill to relocate the liquid waste. With BOD content with range 25,625 to 39,616.7 mg/l and COD content with range 117,333.3 to 146,333.3 mg/l, this condition will generate a serious problem for environmental pollution. Therefore, it is important to test the characteristics of waste oil from each pond. The hexane solvent extraction method is used to separate the oil from the liquid waste. The first pond contains 51.3% water, 21% oil, 2% sludge & sediment and 5.6% free fatty acids. The second pond contains 86.7% water, 16.1% oil, 2.4% sludge & sediment and 8% free fatty acids. The third pond contains 74% water, 6.8% oil, 3.1% sludge & sediment and 12.2% free fatty acid and the fourth pond contains 78.7% water, 3.7% oil, 2% sludge & sediment and 13.3% free fatty acids. Based on the results of this research, the characteristics of POME and its oil losses are the fraction of oil wasted from Crude Palm Oil (CPO) processing, whereas CPO has characteristics as a raw material for Biodiesel. POME should be processed into biodiesel since the liquid waste is discarded from palm oil mill, so there is no need a big land to make waste storage ponds.
