Abstract

ENGLISHThe amount of waste generation continued to increase in Indonesia due to economic development and population growth. In addition, the diversity of solid waste becomes another problem since products made from plastics became widely used and were discarded in large amounts. Plastic waste can be converted into fuel through pirolisis in order to reduce the amount of plastic waste as well as to produce alternative fuel. Pyrolysis is a process of thermal degradation in the absence of oxygen. The objective of this study is to investigate and to compare the performace of fuel produced by pyrolisys, kerosene and diesel oil. The performance of those fuels is investigated in 4 parameters including density, burning time, temperature of water and the volume of water evaporated. The result of this study are 1) the density 0.8 g/ml; burning time 4.02 minutes; water temperature 75°C and water evaporated 12.6 ml. 2) Compared to kerosene and diesel oil, the quality of the fuel is lower than kerosene and higher than diesel oil in all parameters. INDONESIAPertumbuhan penduduk dan ekonomi menyebabkan terjadinya peningkatan produksi sampah khususnya sampah plastik. Pirolisis merupakan proses perekahan atau pemecahan rantai polimer menjadi senyawa yang lebih sederhana melalui proses thermal (pemanasan/pembakaran) dengan tanpa maupun sedikit oksigen. Sampah plastik bisa diurai dan diubah menjadi bahan bakar yang memiliki nilai kalor yang tinggi melalui proses pirolisis. Penelitian ini bertujuan untuk mengetahui dan membandingkan kemampuan minyak hasil pirolisis plastik dengan minyak tanah dan solar dalam hal massa jenis, lama pembakaran, temperatur air dan volume air yang hilang (menguap) saat dimasak menggunakan minyak tersebut. Hasil penelitian menunjukkan bahwa 1) massa jenis minyak pirolisis adalah 0,8 g/ml. Waktu yang dibutuhkan untuk membakar habis suatu benda adalah 4,02 menit. Pemasakan air menggunakan bahan bakar minyak pirolisis menghasilkan temperatur 75°C pada waktu pemasakan 4 menit dengan volume air yang hilang (menguap) sebesar 12,6 ml. 2) Dari 4 parameter yang diamati, kualitas minyak pirolisis berada di bawah minyak tanah namun di atas minyak solar.

Abstract

Even though biogas technology has been introduced in Indonesia since 1990’s and having the potential, the rate of biogas adoption in Indonesia runs slowly. It is important to understand factors encouraging or discouraging potential adopters to build biogas plant. The development of livestock sector especially cattle farming in Indonesia can be seen as the opportunity to increase the rate of biogas adoption. This study investigated the factors affecting households of cattle farmer to adopt or not to adopt biogas technology. A cross-sectional research survey was carried out by using structured questionnaires as the primary tool to collect data from both biogas adopters and non biogas adopters in Pati regency, Indonesia. Socioeconomic characteristic of potential biogas adopters plays an important role to ensure the adoption of biogas technology sustainable. Socioeconomic characteristic regarding having high social status determines individual to adopt biogas relatively earlier than other members of a social system. Having high income and education enables traditional farmers to finance biogas plant by their own money or access aid from the government or other agencies. Among other attributes of innovation, relative advantage of installing biogas plant is the most determinant attribute to speed the rate of biogas adoption. Having biogas plant was perceived as better option and generated more benefits compared to previous technology or method.Article History: Received May 17th 2017; Received in revised form August 5th  2017; Accepted Sept 6th 2017; Available onlineHow to Cite This Article: Wahyudi, J.

Abstract

Biogas plays an important role in supporting and ensuring the dairy farming sector remains sustainable. Biogas technology is not only as a method to dispose dairy farming waste but also benefiting economically, socially and environmentally. Biogas technology has been introduced since 1970s and many biogas programmes have been implemented in Indonesia. However compare to other countries like China and India, the dissemination of biogas technology in Indonesia runs quite slowly. There are several factors such as financial, policies and people’s perception hindering biogas use regarding the increase of biogas plants installed in Indonesia. In addition, many installed biogas plants are non-functional due to inadequate maintenance causing users stop to operate biogas plants and influencing potential users to reject adopting the technology. This paper provides an overview of biogas production sustainability which consists of five sustainability dimensions: technical, economic, social, environmental and organizational/institutional sustainability. Understanding the biogas sustainability helps stakeholders to realize that in order to promote biogas technology many sectors must be developed and many institutions must be involved and cooperated. The sustainability of biogas will determine the success of biogas dissemination particularly in dairy farming in the future.

Abstract

ENGLISHOpen burning is one of methods to manage municipal solid waste in particular in rural areas.  On one hand, open burning is easy and cheap for waste management to eliminate waste. On the other hand, burning of waste causes adverse impacts on the environment and health. One of the negative impacts of open burning is greenhouse gas (GHG) emission causing global warming. This study aimed to calculate and to compare GHG emissions from open burning of MSW in Pati Regency using Tier 1 and Tier 2 of IPCC method. Primary data was obtained through focus group discussions while secondary data was obtained through literature studies. The results showed that GHG emissions from waste combustion in Pati Regency based on Tier 1 and Tier 2 calculations indicating an increase during the period 2013-2017. The average of GHG emissions which is calculated by using Tier 1 is 5.18 GgCO2eq/year. This means it is lower than the average GHG emissions which are calculated by Tier 2, namely 33.86 GgCO2eq / year. INDONESIAPembakaran sampah secara terbuka merupakan salah satu alternatif pengelolaan sampah yang banyak dipilih oleh masyarakat khususnya perdesaan. Di satu sisi, pembakaran sampah merupakan metode pengelolaan sampah yang mudah dan murah untuk menghilangkan sampah. Di sisi lain, pembakaran sampah memberikan dampak negatif bagi lingkungan dan kesehatan. Salah satu dampak negatif pembakaran sampah adalah munculnya emisi gas rumah kaca yang menyebabkan terjadinya pemanasan global. Penelitian ini bertujuan untuk menghitung dan membandingkan emisi GRK dari pembakaran sampah permukiman di Kabupaten Pati menggunakan metode yang dikembangkan oleh IPCC dengan 2 tingkat ketelitan yang berbeda yatu Tier 1 dan Tier 2. Data primer diperoleh melalui pelaksanaan diskusi kelompok terfokus sedangkan data sekunder diperoleh melalui studi literatur. Hasil penelitian menunjukkan bahwa emisi GRK dari pembakaran sampah di Kabupaten Pati berdasarkan perhitungan Tier 1 dan Tier 2 menunjukkan peningkatan selama periode 2013-2017. Emisi GRK rata-rata yang dihitung dengan Tier 1 sebesar 5,18 GgCO2eq/tahun. Hal ini berarti lebih rendah dibandingkan dengan  rerata emisi GRK yang dihitung dengan Tier 2 yaitu sebesar 33,86 GgCO2eq/tahun.

Abstract

ENGLISHSeveral studies founded the usage of hazardous materials for food additives in many parts of Indonesia. Stakeholders especially The Government already implemented policies to against the abuse of hazardous food additives like the enactment of food regulations and food safety promotions. Many factors cause many people still using and distributing hazardous food additives (e.g. economic factors, knowledge and law enforcement). This paper provides an overview of types hazardous food additives and the negative impacts of consuming the additives on health emphasizing in the most popular of hazardous food additives namely formalin, borax and rhodamine B. In general, consuming the additives causes long-term health problems like cancer. However, consuming the additives in high dosage will make the consumers experiencing chronic poisoning and even causing death. Campaigns regarding food safety followed by law enforcement are very important actions to be done to eliminate the abuse of hazardous food additives. INDONESIABeberapa studi menunjukkan banyaknya penggunaan bahan yang berbahaya dan dilarang untuk digunakan sebagai bahan tambahan pangan. Pihak terkait khususnya pemerintah telah mengimplementasikan kebijakan untuk menekan penyalahgunaan BTP antara lain dengan pemberlakuan peraturan dan sosialisasi mengenai BTP. Beberapa faktor menjadi penyebab masih maraknya penggunaan BTP berbahaya antara lain faktor ekonomi, pengetahuan dan penegakan hukum. Ulasan ini akan memaparkan mengenai jenis BTP berbahaya yang sering digunakan dan dampak yang ditimbulkan akibat mengkonsumsi BTP tersebut bagi kesehatan dengan menekankan pada 3 jenis bahan terlarang yang paling sering digunakan sebagai BTP yaitu formalin, boraks dan Rhodamin B. Secara umum, mengkonsumsi BTP berbahaya akan memberikan dampak buruk bagi kesehatan dalam jangka panjang misalnya kanker. Namun, konsumsi BTP berbahaya dengan dosis yang tinggi dapat menyebabkan efek negatif langsung pada kesehatan misalnya keracunan bahkan kematian. Sosialisasi diikuti dengan penegakan hukum perlu terus dilakukan untuk mengatasi penyalahgunaan BTP berbahaya.

Abstract

The agricultural sector is one of the significant contributors to the regional economy of Pati Regency. However, this sector declined at the growth rate of -0.20% in 2021. One of the reasons is the weak capacity of farmer groups indicated by the main class farmer groups, which only amount to four out of 2,588 groups. Department of Agriculture data shows that the total number of farmer groups is 2,588, divided into 1,612 beginner groups, 830 advanced groups, 78 middle groups, four main groups, and 64 unknown groups. The purpose of the study is to determine the criteria and subcriteria in the management of farmer groups. This quantitative study uses the Analytical Hierarchy Process with 56 respondents. Based on Guidelines for Assessing the Ability of Farmer Groups Classes, farmer group management is influenced by five criteria: planning, developing farmer group leadership, organizing, implementing, and controlling reports. The results showed that the Implementation Criteria prioritize managing farmer groups. Meanwhile, the priority subcriteria in the Implementation Criteria is Business Implementation. One of the implementations is to run the Integrated Farming System (IFS) as part of the Business Implementation subcriteria.
