Abstract

Shallot farming productivity refers to the ecosystem supporting. This study aims to analyze the difference between productivity and income of shallot farming based on the distance from the water resources. Additionally, factors that affected the farmer's income were also studied with a survey approach by using purposive sampling in Wanasari District, Brebes Regency. The data collected through interviews with the questionnaire. The data were analyzed by using productivity analysis, income analysis, Kruskal-Wallis Test, and multiple linear regression analysis. The results showed that there was a difference in farmer's productivity and income based on the distance to the water resources. The productivity of shallot in Wanasari District amounts to 12,780 kg/ha/planting season. Meanwhile, the farmer's income in Wanasari District amounted to IDR 57,677,334/ha/planting season. According to the data analysis, factors that affect the shallot farmers' income were shallot price, productivity, the amount of TSP and NPK fertilizers, and the amount of pesticide applied.

Abstract

Crude palm oil (CPO) is one of the leading export commodity that has contributed greatly to the Indonesian economy. The majority of CPO production is exported to various destination countries such as India, China, Pakistan, the Netherlands, and Malaysia. The proportion of Indonesian CPO exports was 80-75%, and domestic consumption was only 20-15% of total production. Indonesian CPO exports still show an increasing trend. This study aims to identify the factors that affect Indonesian CPO exports using the data from 2002-2017. This research used the multiple linear regression method of Ordinary Least Square (OLS). The results showed that CPO production, CPO prices in the international market, CPO prices in the domestic market, crude oil prices in the international market, the exchange rate of rupiah, and export rates had a significant effect on Indonesia's CPO export.

This study analyzed the roles of social capital in rice breeding at Kassiloe village of La’bakkang Subdistrict,Pangkep Districtand provided recommendations on strategies to strengthen social capital based on informal institutions that can be applied or implemented by farmers groups. Data were solicited through face to face interviews and focus group discussion (FGD) to farmers and rice seed breeding practitioners. Qualitative and quantitative SWOT analyses were performed to determine the best strategy to improve rice seeds at the study site. Based on the research findings, a strategy was developed (Strengths - Threats) to improve extension agents’ creativity to motivate farmers, enhance farmers groups meeting to utilize certified seeds. Strategy (Weakness – Threats) to centralize trainings using demplot seeds from the breeding sites, the use of efficient alsintan and application of modern agriculture technologies. Strategy (Strengths – Opportunities) to enhance communication and groups’ meetings to widen the demplot using seeds from the breeding activities, continued planting schedule synchronization and strategy (Weakness – Opportunity) to agree on the selling price of the bred seeds so that all the groups’ members can get some profit, massive and measured agriculture technologies applicationin order to give equal profit to all group members.

The results showed that there were Trichoderma sp. obtained from shallot fields in the village of Sidera. In vitro test results showed Trichoderma sp., which was found to be able to inhibit the growth of the fungus F. oxysforum. The highest inhibition reached 69.18% within six days. As a comparison of inhibition of Trichoderma harzianum, a laboratory collection, within 6 days only reached 61.06%. Trichoderma sp. the origin of shallot fields was more effectively used as a biological agent in controlling FBR disease.
