Abstract

Abstract- East Kalimantan, especially Kutai regency produces 1,112,442 tons/year of palm oil. Oil palm empty fruit bunches (EFB) are one of the wastes generated in the processing of palm oil that is equal to 20-23% of the fresh fruit bunches, so the amount of EFB that can be generated is 244,737.24 tons/year. The purpose of this study is to determine the effect of palm sugar as a nutrient to nutrient nitrogen EM4, phosphor and potassium in composting EFB. This research was conducted by varying the mass of Palm Sugar: 0.4000 g, 0.6000 g, 0.8000 g, 1.0000 g and 1.2000 g. The main composting process that was carried out by adding EM4 solution of 10 mL and 100 mL sugar solution into 200 grams EFB, letting it stand for 30 days, and after that the analysis was conducted. The total content of nutrients is highest on the mass of 1.2000 g palm sugar that is 3.174%. The conclusion of this study is the greater the mass of Palm Sugar is added, the greater the concentration of nutrients found in the composting by using bacterial EM4. Keywords: bio-activator EM4, palm Sugar, EFB.

Abstract

Proses produksi biodiesel menimbulkan hasil samping crude glycerol sekitar 10% (w/w). Kadar gliserol dalam crude tersebut masih rendah karena masih mengandung pengotor sehingga perlu pemurnian agar dapat dimanfaatkan untuk bahan baku industri, misalnya industri obat dan kosmetika. Penelitian ini bertujuan meningkatkan kemurnian crude glycerol dengan metoda adsorpsi menggunakan fly ash dan menentukan kapasitas adsorpsinya. Data kesetimbangan adsorpsi asam lemak bebas dalam gliserol didekati dengan Model Langmuir dan Freundlich. Berat adsorben pada penelitian ini berturut- turut 2,5; 5,0; 7,5 dan 10 gram dengan waktu adsropsi bervariasi selama 40, 50, 60 , 70 dan 80 menit. Hasil pemurnian dianalisa kandungan asam lemak bebas dan gliserol. Kadar asam lemak bebas dapat teradsorpsi maksimum ketika pemurnian menggunakan 10 g adsorben selama 60 menit. Kapasitas maksimum adsorpsi sebesar 5,186x10-4 mmol/g. Berdasarkan nilai koefisien korelasi (R2) menunjukkan bahwa model Langmuir dan Freundlich cocok untuk penelitian ini. Kata kunci : adsorpsi, Crude glycerol, biodiesel, fly ash Crude glycerol is a byproduct of the production of biodiesel produced about 10% (w/w) of the weight of biodiesel . Crude glycerol still contains many impurities that cause low levels of glycerol into that utilization is not maximized . Purified glycerol widely used in several fields such as manufacture of drugs and cosmetic. Therefore, there needs to be a process of purification in order to obtain higher levels of glycerol . This study aims to perform the purification of crude glycerol to determine the method of adsorption and adsorption capacity of fly ash. Adsorption processes associated with the equilibrium adsorption performed at constant temperature (isotherms) to obtain the maximum adsorption capacity data. Langmuir and Freundlich models proposed to interpret the data of adsorption equilibrium of free fatty acids in the glycerol . This research was carried out by varying the mass of adsorbent 2.5g , 5.0g , 7.5g and 10g, and the adsorption time 40, 50, 60, 70 and 80 minutes. Purification of crude glycerol were analyzed using analysis of free fatty acids and glycerol analysis. The results showed that 10g Mass adsorbent and adsorption time of 60 minutes can reduce Free Fatty Acid (FFA) that glycerol levels increased . The maximum adsorption capacity of 5.186 x10- 4 mmol/g. Based on the value of the correlation coefficient (R2) indicates that the Langmuir and Freundlich models are suitable for this study. Keywords: adsorption, crude glycerol, biodiesel, fly ash

Abstract

Abstrak-Pemanfaatan  sampah organik rumah tangga tiap tahun meningkat karena berbagai permasalahan yang akan timbul seperti polusi udara, dapat menimbulkan dampak penyakit dan bahaya banjir. Sampah yang dapat dimanfaatkan adalah sampah organik berupa sisa sayuran, sisa buah-buahan, sisa daun kering, dan ranting pohon. Sampah organik rumah tangga ini  paling banyak digunakan dalam kehidupan sehari-hari karena kebutuhan akan makanan sehingga kuantitasnya semakin banyak dihasilkan  dan akan menumpuk karena tanah tidak mampu mendegradasi dalam jumLah yang banyak, sehingga dapat merusak lingkungan berupa polusi udara (bau) dan serta dapat menyebabkan dampak penyakit. Seiring dengan dampak yang ditimbulkan maka sampah organik harus diolah dalam lingkungan rumah tangga terlebih dahulu dengan mengubahnya dalam bentuk yang lebih bermanfaat seperti pupuk cair organik. Pupuk cair lebih mudah diserap oleh tumbuhan dan dalam bentuk konsetrat sehingga lebih ekonomis karena dapat diencerkan. Penelitian ini bertujuan memanfaatkan sampah organik rumah tangga  menjadi  pupuk cair dan melihat pengaruh dari bioaktivator EM4 dan Promi terhadap pembuatan pupuk cair dari  kandungan C organik. Metode penelitian yang digunakan berupa bahan baku sampah sayuran berupa kangkung, sawi, bayam dan wortel serta daun kering sebanyak 300 g dibersihkan dan dipotong kecil-kecil kemudian dimasukkan di dalam komposter sebelum di fermentasi di basahkan atau dilembabkan dengan bioaktivator terlebih dahulu kemudian difermentasi selama 7 hari. Proses fermentasi dilakukan dengan variasi bioaktivator 2,5 mL, 5 mL, 7,5 mL, 10mL, dan 12,5 mL. Pupuk cair organik yang dihasilkan dengan menggunakan EM4 dan Promi dapat digunakan sebagai bioaktivator dalam penggunaan pupuk akan tetapi bioaktivator EM4 memberikan kerja yang lebih efektif dalam mengdegradasi sampah organik sehingga menghasilkan kadar C organik sekitar 23% dibanding  bioaktivator Promi sekitar 18% dan begitu juga kandungan senyawa  lain untuk EM4 seperti kadar nitrogen 3,8%, kadar P2O5 3,0% kadar K2O 4,2% sedangkan Promi kadar Nitrogen 3,2%, kadar P2O5 2,5% dan K2O 3,0%. Dari hasil analisa terlihat bahwa bioaktivator EM 4 menghasilkan pupuk cair  dengan C organik yang tinggi di bandingkan dengan Promi. Standar pupuk cair disesuaikan dengan Permentan No 11/2011, tetapi kedua bioaktivator ini bisa digunakan untuk pembuatan pupuk cair organik. Kata Kunci : sampah organik, EM4, promi, fermentasi Abstract- Utilization of household organic waste each year is increasing due to various problems will arise such as air pollution, can have an impact of the disease and the danger of flooding. Waste that can be used are organic waste such as leftover vegetables, fruits, leftover dried leaves and twigs. Household organic waste is the most widely used in daily life because of the need for food so that the quantity is more and more produced and will accumulate because the ground is not capable of degrading in significant amounts, so as to damage the environment in the form of air pollution (odor) and can cause impact disease.Along with the impact of the organic waste to be treated in a household environment prior to turning it into more useful forms such as liquid organic fertilizer. Liquid fertilizers are more easily absorbed by plants and in the form konsetrat so it is more economical because it can be diluted. This research aims to use household organic waste into liquid fertilizer and see the impact of bio-activator EM4 and Promi to manufacture liquid fertilizer from organic C content. The method used in the form of waste materials vegetables such as kale, mustard greens, spinach and carrots as well as dried leaves 300 g cleaned and cut into small pieces and then put in the composter before fermentation in lightly mist or moistened with a bio-activator before hand and then fermented for 7 days , The fermentation process is done with a variety of bio-activator 2.5 mL, 5 mL, 7.5 mL, 10 mL, and 12.5 mL. Organic liquid fertilizer produced by using EM4 and Promi can be used as a bio-activator in fertilizer use but bio-activator EM4 provide more effective work in mengdegradasi organic waste to produce high levels of organic C approximately 23% compared to bio-activator Compromise approximately 18% and so is the content of other compounds EM4 such as nitrogen for 3.8%, 3.0% P2O5 content of K2O content of 4.2% and 3.2% Compromise Nitrogen levels, levels of 2.5% P2O5 and 3.0% K2O. From the analysis shows that the bio-activator EM 4 produces organic liquid fertilizer with a high C in comparison with the Compromise. Standard liquid fertilizer tailored to Permentan No.11/2011, but both bio-activator can be used to manufacture organic liquid fertilizer. Keywords: Organic Waste ,, EM4, Compromise, Fermentation
