Abstract

Sektor pertanian dan perkebunan membutuhkan pupuk yang memadai dan dengan harga yang terjangkau untuk menjaga ketahanan pangan nasional. Industri pupuk saat ini terkendala oleh terbatasnya pasokan bahan baku, serta pada tingkat pengguna masih terjadi pola pemupukan yang kurang efisien. Pupuk SRF NPK adalah jenis pupuk yang dikembangkan untuk memberikan solusi khususnya pada elemen tabungan N (urea) dan untuk mendorong petani untuk menggunakan pupuk yang mengandung senyawa yang memiliki unsur hara yang lengkap (N, P, K dan zat gizi mikro) . Aplikasi pupuk SRF NPK diharapkan dapat memberikan dampak ekonomi yang signifikan pada tingkat produsen pupuk, petani dan mampu memberikan multiplier effect di sektor-sektor pembangunan lainnya.Kata kunci : Pupuk, SRF NPK, Dampak ekonomiAbstractAgriculture and plantation sector requires adequate fertilizer and at an affordable price to maintain national food security. Fertilizer industry is currently constrained by the limited supply of raw materials, as well as at the user level is still happening fertilization patterns are less efficient. SRF NPK fertilizer is a type of fertilizer that was developed to provide solutions in particular on the savings element of N (urea) and to encourage farmers to use fertilizers containing compound that has a complete nutrient elements (N, P, K and micro nutrients). SRF NPK fertilizer application is expected to provide significant economic impact (significant) level either fertilizer producers, farmers and able to provide a multiplier effect in other sectors of development.Keywords : Fetilizer, SRF NPK, Economic impact

Abstract

AbstractPotential coal reserves in Indonesia are very abundant, but which became the key issue is the utilization in Indonesia is still not optimal. One alternative to use the coal is by converting it into synthetic gas (syngas), containing primarily hydrogen (H2) and Carbon Monoxide (CO). To create synthetic gas from coal there are 4 kinds of process technology known in the world, i.e. Fixed-bed gasifier, Fluidized-bed gasifier, Entrained-bed gasifier and Molten bath gasifier. There are 3 types of chemical industry to take advantage of this synthetic gas as an alternative of their raw materials i.e., methanol, formic acid and ammonia industry. Currently they use natural gas as raw material. The more widespread use of natural gas for a variety of needs can disrupt the natural gas supply for these industries in the future. Therefore, this synthetic gas can be used as an alternative of raw material supply for these three types of chemical industry in the future. AbstrakPotensi cadangan batubara di Indonesia sangat melimpah, namun yang menjadi isu utama adalah pemanfaatannya di Indonesia masih belum optimal. Salah satu alternatif pemanfaatan batubara tersebut adalah dengan mengkonversi batubara tersebut menjadi gas sintetik (syngas) yang kandungan utamanya adalah Hidrogen (H2) dan Karbon Monoksida (CO). Untuk membuat gas sintetik dari batubara ini ada 4 macam teknologi proses yang telah dikenal di dunia yaitu Fixed-bed gasifier, Fluidized-bed gasifier, Entrained-bed gasifier dan Molten bath gasifier. Ada 3 jenis industri kimia yang dapat memanfaatkan gas sintetik ini sebagai alternatif bahan bakunya yaitu industri metanol, industri asam formiat dan industri amonia. Saat ini mereka menggunakan gas alam sebagai bahan bakunya. Semakin meluasnya penggunaan gas alam untuk berbagai macam kebutuhan dapat menyebabkan pasokan gas alam untuk ketiga jenis industri ini terganggu di kemudian hari. Oleh karena itu gas sintetik ini dapat dimanfaatkan sebagai alternatif pasokan bahan baku untuk ketiga jenis industri kimia tersebut kedepannya.

Abstract

POME (Palm Oil Mill Effluent) can be used as for biogas production, with the main content of (65%) methane gas (CH4) and 35% Carbon Dioxide (CO2), H2S, and H2O gases. Apart from being a gas fuel and a source of electricity generation, biogas from POME waste as well as a waste processor becomes more environmentally friendly (according to quality standards). In order to support the process production of biogas from POME by using Continuous Stirred Tank Reactors (CSTR), it is necessary to decrease POME’s temperature to meet the requirements of the reactor operating conditions. Cooling process by using a Cooling Tower through direct contact between fluids can be a good alternative to be used as a POME cooling method because of its effectiveness in heat exchange and smaller area needed than an open ponds. The type of cooling tower used is the Induced Draft Cooling Tower. In cooling tower design, the steps involved in determining the basic design, calculation of tower dimensions, basin, fan power, losses, and cooling air requirements. Based on the calculation, the tower dimensions determine a height of 5 m, length of 3.6 m, and width of 2.5 m, while the basin cooling tower dimensions determine a height of 2.7 m, length of 3.6 m, and width of 2.5 m, fan power of 5 hp. The cooling air requirement for the POME cooling process is 82,895.14 kg/hour. Keywords : POME; Cooling Tower; CSTR; Fuel; Biogas
