Abstract

This research was proposed to increased the potency of shanks, esspeciality their skin by hidrolising the collagen (by extrating with solvent) into gelatine products. This research was run on a Completely Randomized Design (CRD). The experiment was run in factorial designs of 2 x 3. Factor I was solven type chloroform-ethanol and heksana-etanol, Factor II was a combination of ratio of 1:1, 1:3, and 3:1. The variable in this research were pH, viscosity, rendement, protein, and fat of gelatine contents. Result of the research indicated that the pH value of gelatine was between 8.21-8.52. The solvent of chloroform-ethanol gave the best result (P<0.05) on the ratio of 1:3. Percentage of rendement of gelatine was highest obtained from chloroform-ethanol types compared with that of hexane-ethanol (P<0.05). The interaction combinations of chloroform-ethanol on the ratio of 1:1 would result in the rendement percentage to be higher than others (P<0.05). Otherwise, the solvent of hexane-ethanol might bring impact to the viscocity of gelatine (P<0.05) compared to chloroform-ethanol. The interaction combination of hexane-ethanol ratio gave the best result (P<0.05) with highest level of viscosity on the ratio of 3:1 and lower on 1:3. The content of gelatine protein was highest (P<0.05) for the combination of hexane-ethanol compared to that of chloroform-ethanol. The solvent of chloroform-ethanol types could degrade more component of gelatine fat (P<0.05) compared to that of hexane-ethanol. It could be concluded that the research that the content of gelatine protein from extraction by hexane-ethanol on the combination ratio of 3:1 brought the highest quality compared to others.

Abstract

AbstractThe objective of this study is to develop the optimal solution model for food productiontechnology of integrated farming system (SIMANTRI) to support sustainable agriculture inBali. Primary data under survey method towards 20 farmers of the SIMANTRI 068 in BulelengRegency and secondary data from appropriate sources were used to specify parameters ofthe model. Linear programming approach was used to analyze constrained optimizationproblem of the model by using BLPX88 package program. A small farming system with farmscale of 0.58 hectare, which integrates food and horticulture crops and bali cattle, wasoptimally operated by farmer. It is indicated by optimal solution of the model which conformsto observed behavior. The maximum farming system’ income that was generated from theoptimal model was Rp21,658,160 per annum. The integrated farming system (SIMANTRI068) is potentially sustainable since it can fulfil sustainability criteria: economically viable,environmentally sound, socially acceptable, technically and culturally appropriate.

Abstract

Cibodas Botanic Garden, as ex situ conservation areas, preserves living materials ofthe wet mountains flora. Recently, bioprospecting study for dye in this areas has not yetbeen done. Therefor, the aim of this study was to inventory of natural dye in Cibodas BotanicGarden. Sampel were collected by exploration methods. Parts of plants, kinds of color andits chemical compound were recorded based on observation, interview with nurseries andliterature study. A total of 122 species that belongs to 57 families were potentially source asnatural dye, 23 of them has been traditionally used as natural dye in the various places inIndonesia. The plant family of Fabaceae, Rosaceae, Symplocaceae, and Myrtaceae are themost families that used as a source of dye. The color can be produce are ranging from red,purple, yellow, black, brown, green, blue, and orange. The plant organs used as a source ofdye are roots, stems, leaves, flowers, and fruit. Begonia semperflorens,Berberis nepaulensis,B.fortunei, Symplocosspp., Liquidambar formosana, andDiospyros kaki were potentially fornatural dye, as reported from other countries.

Abstract

Pertanian dan perubahan iklim adalah dua hal yang saling berkaitan, diindikasikan oleh peranan nyata pertanian dalam menyumbang emisi gas rumah kaca dan pertanian merupakan salah satu sektor yang dipengaruhi oleh perubahan iklim. Emisi gas rumah kaca terutama karena penggunaan energi fosil dan peningkatan biaya bahan bakar fosil diakibatkan oleh peningkatan permintaan bahan bakar global, hal ini mendorong banyak negara berkembang mencari sumber bioenergi baru. Paper ini bertujuan untuk mendiskusikan bagaimana mengembangkan bioenergi di bawah kondisi perubahan iklim tanpa mengganggu ketahanan pangan. Analisis deskriptif terhadap data sekunder yang diperoleh dari berbagai sumber digunakan untuk mendiskusikan masalah tersebut. Bioenergi, yang diproduksi dari biomasa dapat dibakar langsung atau diproses lebih lanjut menjadi bahan bakar padat, cair atau gas. Pengembangan bioenergi dapat merevitalisasi sektor pertanian, menciptakan lapangan kerja dan menyediakan sumber pendapatan bagi kehidupan perdesaan, meningkatkan akses perdesaan terhadap energi secara kontinu, meningkatkan panen terhadap tanaman pangan dan penghasil energi, dan secara nyata berkontribusi positif terhadap pemecahan masalah iklim. Tetapi, bila tidak dikelola secara berkelanjutan, pengembangan bioenergi dapat mengancam ketahanan pangan. Mengingat peluang yang diberikan dan resiko yang ditimbulkan, maka kriteria keberlanjutan untuk industri bioenergi perlu ditetapkan dengan jelas.

Abstract

A permanent 1 ha (100 m × 100 m) plot with 25 subplots (quadrates) and 5 level rows ofaltitudinal difference was established for long-term monitoring of plant diversity and dynamicsin a tropical mountain forest of Pohen Mountain, Batukahu Nature Reserve, Bali, Indonesia.Enumeration of all tree species > 10 cm DBH (diameter at breast height) yielded a total of notless than 300 individuals that belonged to 24 species and 19 families with Podocarpaceae wasthe most abundant family in the forest. Plant density varied from 10-20 individuals/quadrates(20 m × 20 m). Species composition and diversity varied between each quadrates in a rowwithin the 1 ha plot. Third row (intermediate altitude) exhibits the highest species diversitywhereas the fifth row (the highest altitude) had the lowest species diversity. Ordinationanalysis showed that species composition in the first, second and third rows are differentwith species composition in the fourth and fifth row. Most of the pioneer tree species exhibitedclumped distribution over the plot. This study provides baseline information for themanagement and restoration on the tropical mountain forests of Pohen Mountain, BatukahuNature Reserve post wildfire in 1994.

Abstract

Land use change in a watershed could affect the ecological system, hydrological system and water quality, meanwhile land use change study is needed to conduct especially in Badung watershed. The purpose of this research is to calculate land use changes from 1992 to 2008 and predicted hectarege of land use in 2015 and 2020. Methods of this research are comparing the four land use maps obtained from Bakosurtanal (1992 and 2000), Interpretation of Landsat ETM+ image (2003), and interpretation of ALOS/AVNIR-2 image (2008). On-screen method is used to ALOS/AVNIR-2 image data interpretation. The equation obtained from logarithmic regression is used to predict the land use area. The results of this research showed that the land use in Badung Watershed region has changes from 1992 to 2008. Settlement land use has the largest changes, where the area is increase. The speed of land use change of settlement reached 46,45 ha per year, while the ricefield land use reached 38,91 ha per year. Predicted settlement area in 2015 and 2020 is 2056,83 ha and 2108,83 ha, while the ricefield is 1386,79 ha and 1343,66 ha.

Abstract

Environmental Management System (EMS) is very important in pursuing sustainable development. Problems were then arising, how to implement SML in the dimension of the Tri Hita Karana, Balinese life philosophy, so it is fit with Balinese life. Thus planning, doing, checking, actuating and controlling should be applied in the dimension of spiritual, socioeconomy (community) and environmental aspects, three aspects on the Tri Hita Karana philosophy. Because tourism is a major source of income for the Balinese it is then interesting to see how the EMS which adopt the THK philosophy being implemented in Bali. Many things can be learnt from its implementation on tourism sectors, especially on hotel businesses.
