The Subject

Innovation in production use of insects allows us to speak about entomo-industry, which could cause in the future a drop in the relative cost of food. On the basis of biotechnology by using the fly Hermetia illucens the article draws theoretical and applied economic conclusions. Larvae of this fly by eating organic wastes during a few days can grow in hundred times and become a feed for animals, a basis for medicine or even a nutritious supplement, while their waste can become a fertilizer (zoo-humus). From means of labour they turn into the subject of labour with selfreproduction and solution to ecological problem, which can create the added value. In traditional livestock breeding fast transformation does not take place and animal acts mainly as the subject or means of labour. Commercialization of the technology can be achieved through development of module equipment for each of 9 processes and this can make it possible to purchase it stage by stage, depending on the need and resources. Due to this fact competitive advantage for technological entrepreneurship can be provided that can take one of the following three types: in the narrow sense (developing and selling equipment), in the broad sense (manufacturing the product with own equipment) and mixed one (manufacturing and selling of the equipment and finished product, joint work of the developer and user of the equipment). The author designed a synthetic graphic business-model of entomo-technological entrepreneurship. Logical schemes of waste treatment were put forward: centralized and decentralized. It was found out that for agricultural waste the decentralized scheme is more appropriate, as it implies treatment at the place of shaping and economizing on transportation. In Russia the process of commercialization of biotechnologies with the use of Hermetia illucens started in 2015, which is proven by patent activity. However, the market develops rather slowly.

Potro yang berada di Kecamatan Pakem, Kabupaten Sleman, merupakan daerah pertanian dengan tanaman utamanya padi dan salak pondoh, selain kelapa dan buah–buahan yang ditanam di pekarangan. Selama ini, buah salak pondoh (Salacca zalacca) dan kelapa hanya dimanfaatkan pada bagian daging buahnya, sedangkan bagian lainnya dibuang sebagai limbah dan tidak termanfaatkan, yang justru sering menimbulkan masalah. Oleh karena itu, pengabdian masyarakat ini dilakukan dengan tujuan untuk memberikan nilai tambah pada limbah pertanian melalui pengolahan menjadi berbagai macam produk, serta meningkatkan pengetahuan, wawasan dan ketrampilan masyarakat dalam pengelolaan dan pemanfaatan limbah pertanian. Sasaran utama kegiatan ini adalah anggota PKK yang mempunyai ketersediaan waktu luang lebih banyak dan mempunyai kegiatan rutin dalam pemberdayaan ekonomi. Untuk mencapai tujuan tersebut, dilakukan beberapa metode kegiatan yaitu penyuluhan, demonstrasi dan pelatihan praktek pengolahan limbah; serta pendampingan dan monitoring evaluasi. Hasil kegiatan pengabdian pada masyarakat menunjukkan bahwa limbah pertanian berupa biji salak pondoh diolah menjadi kopi biji salak, dan sabut kelapa dapat diolah menjadi keset yang bernilai ekonomi, serta anggota PKK mendapatkan pengetahuan, wawasan, dan ketrampilan dalam mengolah limbah pertanian.Kata kunci : limbah pertanian, pengelolaan, sabut kelapa, biji salak pondoh, bermanfaatAbstractPotro which is located in Pakem Subdistrict, Sleman Regency, is an agricultural area with mainly rice and pondoh snakefruit (Salacca zalacca), in addition to coconut and fruits planted in the yard. So far, pondoh snakefruit and coconut are only used in the fruit flesh, while other parts are disposed of as waste and not utilized, which often causes problems. Therefore, this community service is carried out with the aim of providing added value to agricultural waste through processing into various kinds of products, as well as increasing the knowledge, insights and skills of citizens in the management and utilization of agricultural waste. The main target of this activity is members of women organization PKK who have more free time available and have routine activities in economic empowerment. To achieve this goal, several methods of activity were carried out, namely counseling, demonstration and training on waste treatment practices; and assistance and monitoring evaluation. The results of the community service show that agricultural waste in the form of pondoh snakefruit seeds is processed into coffee of zalacca seeds, and coconut husk can be processed into mat that has economic value, and PKK members obtain knowledge, insight, and skills in processing agricultural waste.

This paper analyzes the development of agricultural trade of the countries of the Visegrad Group with emphasis on development of the value of agricultural exports of the individual countries. The subject matter of the analysis is the sensitivity of the commodity structure of agricultural exports of individual countries and the identification of aggregations that are the least and the most sensitive to changes to the external and internal economic environment. From the conducted research, agricultural trade in the V4 countries was found to have developed very dynamically from 1993 to 2008, while the commodity structure of exports has constantly narrowed as the degree of specialization of the individual countries has increased (this applies especially to the Czech Republic, Slovakia and Hungary). From the results of analysis of sensitivity to changes of selected variables relating to the development of the value of agricultural exports of the individual V4 countries, it appears that the aggregations that react most sensitively to changes are those that are the subject of re-exports, followed by the aggregations that are characterized by a high degree of added value. In general it can be said that products of agricultural primary production exhibit less sensitivity in comparison with grocery industry products. This is confirmed by the general trend arising from the very nature of consumer behaviour.

Organic Waste Treatment

Organic waste is the largest composition of waste generated by the people of Indonesia, which is around 50-60%. This type of waste, especially food waste, is easy to smell if it is stored for too long so that it has the potential to pollute the environment. On the other hand, organic waste has good nutrients that can be generated, including through BSF (Black Soldier Fly) maggot bioconversion treatment. The BSF maggot bioconversion method is a method of processing organic waste which is carried out by converting organic matter into other products that are useful and have added value by utilizing biological processes from microorganisms and enzymes. Organic waste treatment with this method is generally carried out on a community-based basis and is integrated with the development of agriculture, fisheries and animal husbandry, because maggot cultivation produces commodities of economic value such as compost and maggot larvae. Compost contains very good nutrients so that it can be used for organic farming and maggot contains high protein that can be used for animal feed and fisheries. The implementation of this program was piloted in the boarding school community, namely the Az-Zakaria Islamic Boarding School which is managed by the Az-Zakaria Islamic Education Foundation (YPI) in Sindangbarang Village, Jalaksana District, Kuningan Regency. The result of this implementation is the formation of a new group of entrepreneurs engaged in the cultivation and utilization of BSF maggots.

Rice straw is a common agricultural waste. In order to increase the added value of rice straw and improve the performance of rice straw biochar. MgO-modified biochar (MRBC) was prepared from rice straw at different temperatures, pyrolysis time and MgCl2 concentrations. The microstructure, chemical and crystal structure were studied using X-ray diffraction (XRD), a Scanning Electron Microscope (SEM), Fourier transform infrared spectroscopy (FTIR), nitrogen adsorption desorption isotherms and Elementary Analysis (EA). The results showed that the pyrolysis temperature had significant influence on the structure and physicochemical property of MRBCs. MRBC-2 h has the richest microporous structure while MRBC-2 m has the richest mesoporous structure. The specific surface area (from 9.663 to 250.66 m2/g) and pore volume (from 0.042 to 0.158 cm3/g) of MRBCs increased as temperature rose from 300 to 600 °C. However, it was observed MgCl2 concentrations and pyrolysis time had no significant influence on pore structure of MRBCs. As pyrolysis temperature increased, pH increased and more oxygen-containing functional groups and mineral salts were formed, while MgO-modified yield, volatile matter, total content of hydrogen, oxygen, nitrogen, porosity and average pore diameter decreased. In addition, MRBCs formed at high temperature showed high C content with a low O/C and H/C ratios.

The purpose of this research is to provide information on sustainable livestock strategies with regard to the environment and social of Papua local communities in the process of cattle breeding process. In addition to increasing the productivity of local livestock, it is required the efficiency of the use of feed materials derived from agricultural waste. This policy should be supported with innovation and technology. Data collection method of this research using two types of data that is primary data and secondary data, primary data obtained from interviews of 30 breeders and the determination of respondents is conducted by way of purposive sampling. Secondary data were obtained from the Livestock Service Office of Merauke Regency, Department of Food Crops and Central Bureau of Statistics (BPS). The field survey results show that in addition to the field grass as the main feed, all breeders use agricultural waste as forage for livestock feed and use little palm oil waste. Types of agricultural waste used are rice straw, sweet potato straw, corn stalks and leaves, and groundnut straw. The highest agricultural waste production is corn stalk and leaves and banana waste both based on fresh produce and dry ingredients. In addition to the most common maintenance pattern is extensively and the best livestock development sites are in elikobel. Site selection based on various things such as location of topography, suboptimal land use, integration pattern optimization, developing local livestock such as poultry and pigs. The conclusion of this research is the strategy of development of sustainable livestock in border area can be conducted in elikobel district with various records such as the need of government policy related to environmentally careful livestock integration system, improving feed innovation and technology, livestock breeding, reproduction technology, and animal disease control to increase productivity and production of local livestock.

Empty Fruit Bunches

In Indonesia especially in Lampung Province, there are a lot of oil palm empty fruit bunches (OPEFB) as an organic material waste. OPEFB is relatively inexpensive lignocellulose material as raw material of cellulose acetate or acetyl cellulose. In a business to bigger added value out of these natural renewable materials, the production of the acetyl cellulose was performed well by the acetylation of cellulose from OPEFB using different methods. These were extensively characterized using thermogravimetric analysis, Fourier transform infrared spectroscopy and X-ray diffraction. The results indicated that the acetyl cellulose resulted showed similar properties to cotton acetyl cellulose. Degree of substitution of the resultant acetyl cellulose from different methods was improved from 1.86 to 2.60.
