Effect of Inoculations of Trichoderma viride and Saccharomyces cerevisiae Mixed Culture on Chemical Composition, Fiber, Digestibility and Theobromine Cocoa Pod Fermentation Muhammad Askari Zakariah
International Journal of Agriculture System VOLUME 4 ISSUE 2, DECEMBER 2016
Publisher : Hasanuddin University

The objective of the study was to identify the effect of Trichoderma viride andSaccharomyces cerevisiae inoculant on chemical compositions, digestibility, and theobromineconcentration of fermented cocoa pod. This experiment consisted of four treatments,namely cocoa pods without fermentation as control (R0); fermentation of cocoa pods withinoculant T. viride (R1); fermentation of cocoa pods with inoculant S. cerevisiae (R2); andfermentation of cocoa pods with inoculant T. viride and S. cerevisiae mixed culture (R3).Each treatment had 3 replicates, and then was fermented for 10 days. Variables observedwere the chemical compositions i.e dry matter (DM), organic matter (OM), crude protein(CP), ether extract (EE), crude fiber (CF), nitrogen free extract (NFE), fiber fraction (Neutraldetergent fiber and acid detergent fiber), in vitro digestibility, and theobromine concentration.Data were analysed by one-way analysis of variance and followed by Duncan’s new multiplerange test (DMRT), if there were any significant difference. Results showed the inoculumaffected (P<0.05) the chemical composition, fiber fraction and in vitro digestibility. However,theobromine was not detected on cocoa pod without fermentation and fermentation.Compared to group R0, inoculation with T. viride and S. cerevisiae mixed culture (P<0.05)resulted in higher DM concentration (92.78% vs 89.72% respectively), higher CP (7.43% vs5.63% respectively), higher NDF (79.41% vs 61.18% respectively), higher ADF (73.04%vs 47.94% respectively), but was not significantly different on DM and OM digestibility(21.22% vs 22.24%, and 22.67% vs 24.31% respectively) than cocoa pod without fermentation.It is concluded that inoculant T. viride and S. cerevisiae mixed culture increased CPconcentration, but had no effect on in vitro digestibility.

Analyzing Determinant Components on East Java Rice Surplus Contribution Using Dynamical System Approach Kuntoro Boga Andri; Nugraha Pangarsa
International Journal of Agriculture System VOLUME 4 ISSUE 2, DECEMBER 2016
Publisher : Hasanuddin University

The Ministry of Agriculture has proclaimed rice as a main food commodity, beside corn, soybeans, meat and sugar. In order to achieve the target of the Ministry of Agriculture, East Java provincial government has stipulated a policy, focusing on rice surplus of 5 million tons in 2014. This attempt is to reach the surplus number through a wide selection of technological innovations (determinant component) that increases the productivity of rice (New Superior Variety/VUB, Site Specific Nutrient Management/SSNM, Integreted Crop Management/ PTT, Jarwo/double row planting system, balanced fertilization, SOP harvest / postharvest), as well as an increase in Planting Index/IP by improving irrigation and food diversification program. By using a dynamical system approach (modeling), it can be measured the contribution of each determinant components in achieving surplus / rice self-sufficiency through simulation. The results of the simulation, it was known that the East Java’s rice surplus will continue to decline from 1,806,282 tons (2014) with 170% self-sufficiency index, fell to 1.706.771 tons (2017) and would be 1.367.901 tons (2025). This condition is due to the increasing number of population, agricultural area continues to shrink and productivity is relatively fixed. Index sufficiency / surplus will increase if there is an interference of educational policy to implement a massive exceed of VUB, SSNM, PTT, Jarwo, balanced fertilization, SOP harvest / post-harvest, IP increasing and the succession of diversification in East Java. A surplus of 4.7 million tons of rice in 2014 within East Java can be achieved by implementing massive educational policy movement of PTT and VUB (100% of the area), the application of SOP harvest / post-harvest to reach at least 50% of the area of paddy and controlling OPT strictly. The highest self-sufficiency index (281%) and a surplus of 5.22 million tons will be achieved in case of an interference in implementing policy of PTT jarwo (100% of the area) and an IP increasing amounted to 1.0 (additional areas that can be irrigated, 33.000 ha). Sustainable rice surplus would be achieved in case of an attempt to make food diversification program completely successful, strengthen family planning programs and strictly guard the Regulation No. 5/2012 on the minimum acreage of paddy fields that must be maintained.

Alternative Food Networks Development and Multiple Actors’ Participation in China: A Review Huan Yang
International Journal of Agriculture System VOLUME 4 ISSUE 2, DECEMBER 2016
Publisher : Hasanuddin University

This article reviews the studies about the alternative food network development in China, summarizes the results and identifies the issues for further research. It first introduces different theoretical perspectives in alternative food network studies in China, including community supported agriculture, nested market, short food supply chains and producerconsumer connection. The causes of rising alternative food networks are the serious food safety problem, the un-balanced power between different actors in the mainstream agrofood system and the increasing number of middle income citizens. Its development close relates to the changes in the international agro-food system. And the government dominates the establishment of the certification system and give limited support to the emerging food networks. The consumers and majority of producers are social elites, and the small scale farmers participate in the networks under the support of intermediaries. Further studies can pay more attention to following issues: the landscape of alternative food networks development in China, the value construction processes between different actors, the role of companies in alternative food network construction and introducing technical perspective of ecological agriculture into research.

Improvement of feed quality for mangrove crab larvae rearing is one of theimportant factors to increase of crablet production. The aim of the research was to knowthe influenzing of enriched Artemia nauplii using Nannochloropsis sp fed to the differentstages of larvae Scylla olivacea on crablet production. Twelve units of tanks volume 250L filled with saline water salinity 30 ppt, aerated, then stocked with new hatched mud crablarvae zoea-1 at the density 100 ind./L. The larvae zoea-1 were fed rotifer, Brachionus sp.and after zoea-3, beside fed by rotifer, the larvae were also fed by Artemia naupli. Fourtreatments were tested, namely: A). Artemia nauplii enriched using Nannochloropsis sp.was given to the larvae zoea-3 until develop to megalop stage. B). Artemia nauplii enrichedusing Nannochloropsis sp was given to the larvae zoea-4 until develop to megalop stage.C). Artemia nauplii enriched using Nannochloropsis sp was given to the larvae zoea-5 stageuntil develop to megalop stage. D). Artemia nauplii without enriched using Nannochloropsissp. was given to the larvae zoea-3 until develop to megalop stage. Result of the researchshowed that the highest of Larvae Development Indexes and Megalop Occurence Indexeswas obtained in treatment A and resulted the highest of crablet production, then followed bytreatment C and B and those were significantly different (P<0.05) with the crablet productionin treatment D. The use of Artemia nauplii enriched by Nannochloropsis sp. to feed larvae,S. olivacea stage zoea-3 to zoea-5 until develop to the megalop stage is one of the key factorto enhance the crablet production. By this finding, the crablet production in hatchery will beincreased and the mud crab culture in brackishwater pond able to developed.

Publisher : Hasanuddin University

Environmental aspects have been some of the most argued about topics in society, including the role of the government as a stakeholder. Deforestation and illegal mining have been destroying the many ecosystems and rainforest habitats, including along the Katingan Watershed. The research objective is to describe public perception and participation in environmental preservation. The research used descriptive qualitative method and applying Spradley Domain Analysis. Primary and secondary data were obtained directly from field informants using interviews, observations and documentation. The research results show that the people’s perception and participation in environmental preservation was categorized into two groups. The first group one stated that they did contributed out of personal and financial interests, whilst the second groups were simply following the instructions of the government and local leaders. In general, locals have different perception on how they utilize the natural resources. The management of natural resources was perceived as being done for economic reasons, with the assumption that it were used sustainably. People’s involvement in preserving nature were affected their own needs either individually or collectively. Participation of the people in the conservation around the watersheds area was done for reasons of individual desire, solidarity, and to follow instructions from the government and Katingan Hilir leader. Environmental effort is carried out in activities aiming to protect and prevent damage to the area of the Katingan River. This lead to argue that diverse people’s perception to preserving environment generates the difference participation in their awareness.

Publisher : Hasanuddin University

The development of rice field agriculture in Indonesia has entered the post green revolution phase. The sociotechnical changes occurred during the green revolution, the economic gap among farmers also ensued amid the increase in production while the social sustainability was maintained. The research purpose is to analyze the institutional adjustment conducted by the farmer society in facing the problems caused by green revolution in order to maintain the social sustainability. For the purpose mentioned above, the case study was carried out in a village in a center of green revolution. The result of the research shows that: (1) The sociotechnical changes had been taking place during the pre-green revolution era, green revolution, and post-green revolution in the form of land management, seeds procurement, planting and managing the crops, and harvest and post-harvest. The sociotechnical changes encouraged the increase in agricultural production in which created the gap between the affluent and the underprivileged in a village and had the potential to disturb the social sustainability of rice field agribusiness. (2) The institutional adjustment occurred in the sociotechnical changes in the forms of land ownership dynamics, employment dynamic and village’s new occupation dynamic. This institutional adjustment has the function to dampen the tension on the marginalized individual actor caused by the post green revolution new social structure. (3) The social sustainability in the rice field agriculture could be maintained because the social tension caused by the post green revolution social technical changes could be dampened by the institutional adjustment. The institutional adjustment by the village community contributed into the social sustainability of the rice field agribusiness.
