Abstract

Indonesia memiliki berbagai jenis tumbuhan yang sangat potensial untuk dikembangkan sebagai pakanternak, salah satunya adalah kacang pedang (Canavalia gladiata (Jacq.) DC.). Kacang pedang adalah jeniskoro yang belum dimanfaatkan dengan optimal. Di Indonesia, bahkan dunia, belum banyak penelitianyang menggali potensi kacang pedang sebagai pakan ternak, padahal pengembangannya sebagai pakanternak alternatif cukup menjanjikan. Untuk mengembangkan lebih lanjut, diperlukan kajian mengenaikarakteristik morfologis dari kacang pedang untuk mencegah ambiguitas taksonomik. Maka dari itu penelitianini bertujuan untuk mempelajari karakteristrik morfologis dari kacang pedang serta potensinya sebagai pakanternak. Penelitan dilakukan selama bulan Mei 2019 sampai Maret 2020. Biji mulai disemai pada bulan Mei(sebagai bulan ke-1) dan dilakukan karakterisasi saat terdapat polong yang sudah matang pada bulan Maret(bulan ke-10). Fase vegetatif berlangsung selama 4-5 bulan sebelum tumbuhan mulai mengeluarkan bungapertama. Fase generatif memiliki durasi yang bervariasi, terutama pada pematangan polong. Kematanganpolong berlangsung selama 5-6 bulan, bahkan lebih. Hasil penelitian menunjukkan bahwa kacang pedang(Canavalia gladiata (Jacq.) DC.) memiliki karakteristik morfologis yang mencolok pada ukuran daun yangbesar, bunga berwarna putih yang harum, polong yang berukuran besar, serta biji yang berwarna merah.Daun dan biji kacang pedang berpotensi untuk dikembangkan sebagai pakan ternak alternatif. Biji kacangpedang mengandung berbagai senyawa nutrien unggulan sebagai pakan ternak.Kata kunci: Canavalia, karakter morfologis, pakan alternatif, pakan hijauan

Abstract

Efforts made to achieve clean and healty environment should not merely put on the responsility of executive institutions only, but also all stakeholders who have concerned on environment including house of representatives. The Environmental Caucus of the house representative are expected to improve survailance, budgetting, as well as release of pro-environment regulations which are predominantly related to environmental management. On carrying out sustainable development, providing main attention on environment on any decisions and regulations made is a must. Therefore the existence of Environmental Caucus of the house representative is important because the institution can push any parties to make decission which are pro to the environment on the parliament levels. If we look at the challenge and chance faced by the Environmental Caucus of the house representative, strong commitment needed by their members to fight for pro-environment supporters and take environmental problems as priority on their political agenda.

Abstract

The experiment of sustainable technology application with casting organic fertilizer and styloassociation with King grass was conducted at Siut Cattle farm at Gianyar regency. The experimentdesign was a randomized block design arranged in Split-plot pattern and was replicated threetimes. The treatment consisted of two factors as follows: (1) two types of cropping systems as mainplot (King grass monoculture and King grass – stylo association), (2) four levels of casting organicfertilizer as sub-plot (0, 10, 20, dan 30 t ha -1). The variable studied were: forage production,production characteristic, and leaf characteristic. Leaf characteristic variable consisted of: leafarea, leaf color, and leaf thickness. The results showed that: casting organic fertilizer weresignificantly (P<0.05) effect on leaf area and leaf production. Cropping system was not significantly(P>0.05) effect on all of variable studied. There was no significantly interaction (P>0.05) foundedbetween cropping system and casting organic fertilizer on all of variable studied. The conclusion ofthese experiment were: casting application at King grass and its association with stylo wasincreased forage production at first regrowth. The optimal levels of casting organic fertilizer in Kinggrass monoculture and that association with stylo were 17.09 dan 16.41 t ha -1 respectively.

Abstract

Garbage is a problem that must be faced by the community, because garbage is a form of environmental pollution, where garbage can have an impact on public health, such as; odors, floods, destroy aesthetics, fire, greenhouse effect and so on. Household waste management requires active community participation so that the role of the government does not get heavier. Increase community participation in waste management in Denpasar City. In an effort to build the effectiveness of waste management in Denpasar City, it is necessary to develop a community-based waste management model in Denpasar City. The purpose of developing a waste management model is to actively involve the community in managing waste in Denpasar City. This study uses the Interpretative Structural Modeling (ISM) method approach by using elements of the affected community, elements of program objectives, elements of indicators to achieve goals, elements of the main constraints and elements of the institutions involved. In compiling the sub-elements from each element, it involves figures, experts, actors and activists in Denpasar City on community-based waste management. The results of the modeling show that the participatory role of the community is very important in reducing waste through reuse, increasing community involvement and implementing 3R activities. The main obstacle in waste management is the limited facilities and infrastructure for waste management and the unclear waste management organization. Possible changes are that law enforcement and waste regulations must be clear and the involvement of all stakeholders in community-based waste management in Denpasar City. Keywords: model; management; waste; society.

Abstract

EFFECT OF NUMBER OF METHANOBACTERIUM AND FERMENTATION DURATION TO METHANE (CH4) GAS PROPORTION IN ORGANIC WASTE PROCESSING IN SUWUNG TPA DENPASARA research has been conducted to find out the effect to the amount of methanobacterium bacteria and fermentation duration toward proportion of methana (CH4) at organic waste processing at TPA Suwung Denpasar. Methana gas produced from this organic waste will be processed become fuel of electric generation. From this study will be expected to get all methana gas that contained at the waste so that there is no methana gas loss to the atmosphere. This study was conducted by using 4 treatments that are without bacteria (B0), bacteria with number of population 106 CFU/ml (B1), bacteria with population of 107 CFU/ml (B2), and bacteria with population of 108 CFU/ml (B3). Each treatment conducted thrice (3) repeat. The four treatments conducted measurement of gas variable after fermentation during 0 week, 3 weeks, 5 weeks, 7 weeks and 9 weeks by uisng gas analyzer GA 2000 Geotech. Data from study result then analyzed by using complicated factorial design (RAL). From ANOVA analysis shows there was significant bacteria number and fermentation duration toward proportion or procentage of methana gas resulted. The longer fermentation time takes place, the bigger the proportion of the methane gas produced. However, the greater number of the bacteria population does not always produce bigger proportion of methane gas To find out the combination which could give best effect the researcher used Duncan test. The result of analysis from Duncan shows that combination at the ninth weeks by number of bacteria 107 CFU/ml giving best result that was percentage of methana gas is 55,10%.
