Abstract

The effort to the economy growth of developing countries is directed to create an integrated zone that will motivate export, invite investors, and be a catalyst of a continuous growing and developing region.  This research is to design agroestat as an integrated agricultural zone under one management based on local specific competitive horticulture with regional development approach.  The research of agroestat is holistic covering the whole value-chain (farming, industry, and trading) of the regional, national, and international process agriculture.  Agroestat make use of a complex and complicated inter-dependency and inter-relation of multidimensional (social, culture, and economy) among sectors (agriculture, industry, and commerce).  Therefore, this research applied, soft, system methodology to design conceptual model of agroestat (soft system) and decision support system (hard system).  The study of agroestat benchmarks to three models of newly specific developed integrated region that is Perkebunan Inti Rakyat (PIR), agropolitan, and ecoindustrial park model.  The conceptual model of agroestate, consist of five individual elements which are infrastructure, district, business, funding, and management.  As a whole it describes the agroestate model.  Regionalization of agroestate is using objective and subjective approach into three (agriculture, industry, and commerce) economic zone on fair free trade competition and decentralization of government policy.  Agroestat in the smallest autonomous area of Kabupaten/Kota applying the integrity concept, needs supports of local government in indirect-subsidies (infrastructure) and regulation (spatial order).  Agroestate needs an independent, professional, commercial institution to manage agroestate.  The validation of Agroestat DSS (decision support system) has been done in Kabupaten Brebes with shallot as local competitive horticulture commodity. Key words: agroestat, agricultural region, agriculture, shallot

Abstract

Co-composting was the composting process uses two or more raw materials to improve the optimization process and material benefits. The purpose of this study was to determine the influence of the initial C/N value ratio and the active aeration usage of the co-composting process of filter cake and boiler ash of cane sugar industry. Co-composting  was done in the aeration pile reactor with 5 kg of mixed material,and uused two factor; initial C/N ratio and aeration. The treatment of  C/N ratio was begun at 30, 40, and 50 from formulation filtercake and boiler ash.   Active aeration was given at 0.4 and 1.2 l /minutes.kg materials that carried out for 1 hour per day  on the first week. From this observation, known that the aeration distiction at 0.4 and 1.2 l /minutes.kg materials does not effect the C/N ratio of  compost.  In the other hand,  the treatment of initial C/N ratio at 30 and 40 was significantly affected with initial C/N ratio at 50 compared by final  C/N value of the compost. Initial C /N ratio at 50 requested the final  C / N ratio of compost at 19-20 that was higher than the treatment of  intial C/N ratio at 30 and 40 which had final C/N ratio at 13-15 and 12-17, respectively.

Abstract

Cibanten river is one of the most potential to be developed as a source of raw water. Crucial issues at Cibanten river is the increasing load of water pollution as indicated by parameter BOD, COD and TSS. This study aimed to estimate the amount of Total Maximum Daily Load (TMDL) in Cibanten river, analyze the quality Status of the Cibanten river water, analyze the capacity of assimilation, and determine management strategy of Cibanten river of Banten Province. TMDL of BOD were determined by modeling Qual2KW and the results were compared with the second class water quality standards to regulation No. 82/2001. Management strategy of Cibanten river determined by analysis of the results of an expert survey method with AHP (Analytical Hierarchy Process). Quality Status of the Cibanten river water with pollution index was light raiment and storet method of Raw Water Quality class II belong was heavy raiment. Results of the simulation calculation of TMDL, the total load of pollution in the Cibanten BOD was730 tons/month while the TMDL of BOD was 146.801 tons/month. Results of the analysis of assimilation capacity COD was 24208 tons/month. Results of the analysis methods of survey expert with AHP (Analytical Hierarchy Process) is monitoring and surveillance as an alternative management strategies with the highest priority of the Cibanten river (agregate value 0.202) and following up the monitoring results.Keywords: Cibanten River, total maximum daily loads, Qual2Kw, assimilation capacity, storet, pollution index, Analytical Hierarchy Process

Abstract

As the evolving of environmental issues over time, the development of environmental management approaches in industries began to shift to the prevention of pollution to reduce environmental impact. However, in practice, many obstacles encountered during the environmental management change to be more proactive. This study aims to explore the barriers of achieving the proactive environmental strategy in a rubber processing industry. Used a case study approach in a natural rubber processing factory, the data was collected through interviews with experts and sources as well as observation in the field. This study shows main barriers that faced by the company consist of financial issue, human resources, communities’ pressure, technological change and communication with environmental experts. The results of this study suggest conducting cooperation with research institutions or environmental experts especially for skills that cannot be controlled by the manager or employees in the company.

Abstract

Seng dross merupakan hasil samping dari industri pelapisan logam (galvanis) dengan proses hot-dip dan mempunyai kandungan seng yang cukup tinggi. Hasil samping ini dapat digunakan sebagai bahan baku seng asetat. Seng asetat digunakan sebagai bahan tambahan makanan, suplemen, obat-obatan, precursor, dan pelega tenggorokan. Penelitian ini bertujuan untuk memperoleh kembali seng dari seng dross untuk menghasilkan seng asetat. Seng asetat tersebut akan digunakan sebagai precursor. Proses ekstraksi seng dross dilakukan dengan asam asetat glasial pada kondisi proses, yaitu waktu ekstraksi 1 jam, 2 jam, dan 3 jam, suhu ekstraksi 130 oC, 150 oC, dan 170 oC, serta konsentrasi asam asetat glasial 20%, 40%, dan 60%. Hasil ekstraksi berupa seng asetat dianalisis untuk mengetahui kadar seng dan karakteristik kristal. Hasil penelitian menunjukkan bahwa kondisi proses ekstraksi yang terbaik diperoleh pada suhu 130 oC, konsentrasi asam asetat glasial sebesar 60%, dan waktu proses ekstraksi selama 1 jam. Seng asetat yang diperoleh mengandung 75,39% seng dan kristal seng asetat mempunyai intensitas 5800 counts.
