Abstract

Tujuan dari penelitian ini adalah menganalisis masalah untuk memperoleh masukan dalam upaya peningkatan pendapatan. Jagung merupakan salah satu komoditas pangan yang penting dan terkait dengan industri besar. Penelitian ini dilakukan secara purposive dengan metode pengambilan contoh yaitu Stratified Random Sampling, sehingga didapatkan responden 38 sampel. Metode analisis data yang digunakan adalah analisis ketersediaan faktor produksi, analisis usahatani, dan analisis fungsi respon produksi dan pendapatan, dan analisis efisiensi alokatif. Hasil analisis menunjukan ketersediaan faktor produksi sudah cukup tersedia dan penggunaan faktor produksi usahatani jagung masih belum efisien. Sehingga produksi yang dihasilkan masih rendah, begitupula dengan tingkat pendapatan petani.

Abstract

Soya bean sauce waste water is an high organic wastewater and has dark colour, therefore it is diffi cult to degrade it biologically. Base on as mentioned above, it is tried to process it with coagulation and fl okulation use Alumunium sulphate and PAC which is added to wastewater with several dosis variation of Alumunium sulphate: 100, 200, 300. 250, and PAC with dosis 50, 100, 150, 200 ppm. Experiment result shows the experiment which use a match Alumunium sulphate and PAC as coagulant could give a good quality of processing and suitable with the treshhold of wastewater. The application of fl okulan Aquaklir 240 could help the performance of coagulan that can be seen from the fl oc size form.Key words : fl occulation, coagulation.

Abstract

The status of indonesian palm oil industry in the world to be the fi rst one that built a modern palm oil industry. There is a trend of palm oil industry in the future time to be the dominan industry. On 2005 was increse to be 5.597.158 ha with CPO production about 12.451.000 ton which is spread in 20 provinces. The increasing of palm oil production give impact to solid and liquid waste potential. All the waste can be used as energy alternatif, beside that the potency of solid and liquid waste will give contribution to CO2 emission of global warming.Key words : palm oil.

Abstract

Seeding in Fixed Bed anaerobic reactor are infl uenced by several condition such as the growth rate total population of microbial, bacterial adaption to infl uent and the retention of biomass in reactor. The aim of this observation is to fi nd out the seeding and acclimation process in anaerobic process by using plastic as support material. Seeding and acclimatization process run smoothly can be seen from the increasing of infl uent or substrate and following by the increasing degradation of soluble COD, beside that the decreasing of VSS concentration indicates that microorganism are all ready fi x in support material, therefore reactor can be operated continuously and the acclimatization process can be stopped.Keywords : anaerobic seeding, acclimation anaerobic process

Abstract

 In this paper, we consider the fuzzy controller problem for nonlinear system using fuzzy models. The controller is constructed using a design model of the dynamical process to be controlled. The design model obtained from the truth model using a fuzzy modeling approach. The Takagi-Sugeno fuzzy model is adopted for fuzzy modeling of the nonlinear system. The truth model represents a detailed description of the process dynamic. The model is used in a simulation to evaluate the performance of the controller design. Stabilization of the closed-loop discrete Takagi-Sugeno systems using the well-known PDC (Paralel Distributed Compensation) technique is investigated. The design procedure we adopt is to convert the design of the controller to a Linear Matrix Inequality (LMI) problem so that the stability of the whole system can be assured.

Abstract

   Organic waste water can be treated biolocally by using anaerobic fixed bed reactor. Fixed bed reactor is bioreactor which is compleeted with support material inside reactor for bacteria fixation in the surface area of support material. The benefit of using this kind of technology are it needs low energy, low nutrien, low sludge production and could treat high organic concentraion waste water.   The support material  has important role in the  Fixed Bed reactor performance, therefore it must be mentioned in several factors those are : size & shape of suport material, ratio of surface area and volume which influences the attach of microorganism, porousity is a waste water volume compare to the total volume and material of support material must inert.   According to the benefit and the principle of Fixed Bed reactor, this kind of technology can be used to treat the organic high concentration to reduce the organic pollutant. Kata kunci : anarobic, Fixed Bed.

Abstract

Sebagian besar industri makanan, termasuk industri tahu membuang limbah cairnya yang mengandung bahan organik dengan kadar tinggi (lebih dari 16,483 mg/L) langsung ke badan air. Dengan menggunakan teknologi yang tepat, limbah cair ini dapat diolah lebih lanjut untuk menghasilkan produk samping berupa biogas yang mengandunggas methan sebagai substitusi energi pada industri yang bersangkutan. Desa Kalisari merupakan salah satu sentra industri UKM tahu, untuk mengolah limbah cair yang dihasilkan oleh industri-industri ini diperlukan reaktor biogas “anaerobic digester “ dengan kapasitas 20 m3. Hasil pengolahan limbah cair ini, disamping dapat menurunkan kandungan bahan organik yang terkandung, juga sekaligus dapat menghasilkan biogas yang produksinya sangat tergantung pada laju beban (loading rate) yang dimasukkan ke dalam reaktor. Tujuan penelitian ini adalah untuk memperoleh laju beban dan produksi  biogas yang optimal sebagai dasar untuk mengetahui unjuk kerja optimal (optimum performance) Fixed Bed reactor untuk mengolah limbah cair tahu dari 25 industri tahu rumah tangga. Kata kunci : anarobic, Fixed Bed. AbstractAlmost of food industries such as tofu industry discharge waste water that high organic content in about 16,483 mg/L and the application method of wase water treatment produce side product such as biogas that contain methane gas, that biogas can used  as energy substitution for the industry itself. According to the experienced in the Kalisarivillage there are a lot of small scale tofu industries , and it was built a 20 m3 bio reactor to treat the waste water. The tofu industry waste water is treated anaerobic by using anaerobic digester. Beside, reducing the organic pollutant, it is also produce biogas depend on the organic loading rate which come to the reactor. In this experiment areto find out the optimum of loading rate and also looking for the optimum gas production. According to organic loading rate can be seen the optimum performance of Fixed Bed reactor.The optimum biogas production is used to run the stoves for 25 households. Key word : anarobic, Fixed Bed.

Abstract

Generally, food wastewater contains high organic matter, therefore the exact wastewater treatment is biological process by using Fixed Bed reactor in anaerobic system. In this observation , showed the comparison between BOD and COD, mass balance and the forming of methane gas (CH4) with variation of hydraulic retention time 11 days, 7 days, 5 days and 3 days. Based on the observation result, the 11 days hydraulic retention time is the most efficient of reactor performance and the best forming of methane gas (CH4) is the 7 days of hydraulic retention.
