Has conducted a study entitled " Cow Manure Waste Utilization and Straw Peanut For Liquid Bokashi For Plant Growth mustard (Brassica juncea L.)". This study aimed to analyze the nutrient content in the liquid Bokashi is derived from cow dung and straw peanuts, and study the effect of dosing Bokashi different liquid to the growth of the mustard plant (Brassica juncea L.). Methods using a completely randomized design with one factor at a dose of 125 ml, 250 ml, 375 ml and 500 ml, and as control using Bokashi solid. This research was conducted with four replications. Bokashi liquid nutrient content of C of 0,1045%, 0,0461% of N, P and K amounted to 0.0172% at 0.2500%. The content of nutrient dense Bokashi C of 6,0874%, 2,0169% of N, P and K amounted to 0,0218% at 5,7802%. Bokashi dosing different liquid to the growth of mustard (Brassica juncea L.) significant effect on the growth of mustard, but still lower than the solid Bokashi. Dose liquid Bokashi most optimal for growing mustard (Brassica juncea L.) is at 375 ml.
Abstract. The aim of this study was to determine the levels of free fatty acids and carboxymethylcellulase activity (cmc-ase) activity of some protected fat-proteins base on in vitro Tilley and Terry method. Two sources of fat, i.e. crude palm oil and fish oil and three sources of protein i.e. skim milk, soybean flour and soybean meal were used in the formulation of protected fat-protein, and thus there were six treatment combinations. The filtrate from the in vitro test was analyzed for the levels of free fatty acids and cmcase activity. The result of this research indicates that different combinations of feed materials and fat give different content of free fatty acid in first stage and second stage in vitro, with the best results in the combination treatment of skim milk and palm oil that give the lowest result of free fatty acid concentration in fisrt stage in vitro (0.168%) and the highest result free fatty acid concentration in second stage in vitro (4.312%) . The activity of CMC-ase was not influenced by different sources of fat and protein. It can be concluded was that the protection of the combination between skim milk and CPO gives the highest protection results.Key words: enzyme activity, free fatty acid, in vitro, protected fat-protein Abstrak. Penelitian ini bertujuan untuk mengetahui kadar asam lemak bebas dan aktivitas cmc-ase beberapa protein lemak terproteksi secara in vitro metode Tilley and Terry. Dua sumber lemak yaitu minyak sawit mentah dan minyak ikan serta tiga sumber protein yaitu susu skim, tepung kedelai dan bungkil kedelai digunakan sebagai bahan untuk membuat protein lemak terproteksi, sehingga terdapat 6 kombinasi perlakuan. Filtrat dari uji in vitro di analisis kadar asam lemak bebasnya dan aktivitas enzim cmcasenya. Dari hasil penelitian ini diperoleh bahwa perbedaan kombinasi sumber protein dan sumber minyak memberikan kadar asam lemak bebas yang berbeda pada in vitro tingkat 1 dan tingkat 2 dengan hasil terbaik pada perlakuan kombinasi susu skim dan CPO yang memberikan hasil kadar asam lemak bebas terendah sebesar 0,168% pada in vitro tingkat 1 dan kadar asam lemak bebas tertinggi sebesar 4,312% pada in vitro tingkat 2. Aktivitas cmc-ase tidak mengalami perbedaan dengan adanya perbedaan sumber minyak dan sumber protein. Kesimpulan dari penelitian ini adalah bahwa kombinasi susu skim dan minyak sawit mentah memberikan hasil proteksi yang terbaik dilihat dari kadar asam lemak bebas pada in vitro tingkat 1 dan tingkat 2.Kata kunci: aktivitas enzim, asam lemak bebas, in vitro, protein lemak terproteksi
This research aim to determine the effect of addition probiotic mixculture on the anaerobic fermentation of coffee peel on the content of dry matter, crude fiber, and crude protein. This research conducted by experimentally using a Complete Randomized Design (CRD) with 4 treatments and 5 repeats. The treatment was P1 (coffee peel + 3% molasses), P2 (coffee peel + 3% molasses + 0.5% Heryaki probiotic), P3 (coffee peel + 3% molasses + 1% Heryaki probiotic), P4 (coffee peel + 3% molasses + 1.5% Heryaki probiotic). The results showed that the addition of probiotic mix culture had no significant effect (P>0.05) on crude fiber and crude protein. The crude fiber (15.738%-17.714%) and crude protein (10.676%-12.019%). The conclusion of this study was that the addition of mix culture probiotics on anaerobic fermentation of coffee peel did not affect the crude fiber and crude protein content.
Biogas is a renewable energy source needed as an alternative potential fuel. This research aims to 1) analyse perceptions and participations of community to the development of biogas in Kecamatan Tamban Catur, Kabupaten Kapuas, 2) identify factors influencing the success of biogas development in Kecamatan Tamban Catur, Kabupaten Kapuas, and 3) analyse the benefits of using biogas for community in Kecamatan Tamban Catur, Kabupaten Kapuas. The research was carried out in Sidomulyo, Sidorejo, and Warnasari Villages in Kecamatan Tamban Catur, Kapuas Regency. The research was conducted using survey data, and the data were further analyzed through descriptive statistics involving 33 respondents who have received the program of biogas development in Kecamatan Tamban Catur Kapuas Regency. The dependent variables were perceptions and participations of community while the independent variables were ages, the number of cattle, education, supporting program, and duration of biogas utilization. The results indicated that community perceptions of the biogas development were positively increasing (78.8%). The F-Test showed that independent variables influencing community perceptions significantly (P<0.05) with 35.1% of coefficient determination (R2). Although community participations to biogas development were relatively high (72.7%), there was no apparent impact (P>0.05) of independent variables to the community participations. Factors influencing the success of biogas development in Kecamatan Tamban Catur were passion, the number of cattle, floor types, applicable technology, and supporting programs from the government agencies. There are several advantages of using biogas for the community. First, the use of biogas improves cost efficiency per month by reducing the usage of fuel/kerosene for about 15 liters (Rp.150.000,-) and the usage of 60 bundles of fire-wood (Rp.120.000,-). Moreover, utilizing solid and liquid organic fertilizer increased daily income for Rp. 10.000,- and Rp. 48.000,- respectively. In addition, biogas application is more environmentally-friendly.
Ecotourism in Sei Gohong Village, Bukit Batu Subdistrict, Palangka Raya City, Central Kalimantan Province requires the appropriate concept of development strategy. SWOT analysis is employed to identify strengths, weaknesses, opportunities, and threats involved and to determine the development strategies that are required. The results of the SWOT analysis indicate that the most appropriate strategy is the WO strategy, which is a strategy that utilizes all opportunities to minimize weaknesses. The WO strategy consists of (1) Increasing various facilities to attract visitor’s appeal, (2) Making the riverbank tourism under good management, (3) Making various attractive packages for tourism, (4) Conducting training for tour guides, security officers and how to improve the additional value of Bawang Dayak for the local community, (5) Enhancing improvement for Pokdarwis in terms of management.
