Abstract

There are approximately 1.4 million hectares of swampy area in South Sumatera, but only 12% of those are being used as farm and plantation.   The purpose of this research was to investigate the similarity of arthropod community inhabiting swampy rice field and its surrounding area. This research was conducted in South Sumatera Province covering regency of Musi Banyuasin and Palembang. Four types of swampy area were selected from each location, i.e. rice field, thicket, bush, and swampy land inhabited by broad-leaf weeds. Pitfall trap used to collect arthropod and it installed at five different times. i.e. 15 days before rice planting, one month, two months, and three months after planting, and 15 days after harvest time. The result showed that relative abundance of predatory arthropod dwelling soil in rice field was 95.03%, and habitat surrounding rice field was 95.12–97.21%. The level of similarity of arthropod species between rice field ecosystem and its surrounding area ranged from 0.73 to 0.84.   Thus, the surrounding area of rice field probably can be used as catchment area of predatory arthropod and other pests during planting season.

Abstract

This research aimed to identify the impact of Pajala program on the productivity of wetland rice in JonoOgevillage, Sigi Biromaru Sub District, Sigi Regency. This research was conducted in September to November 2017. The respondents of 32 farmers were determined using a simple random sampling method.  The tool used to analyze data in this research wast dependent test. The results of t dependent test indicated that the rice productivity was higher after the Pajala program was implemented with the correlation of 0.763 or 76.3%. This suggests that the Pajala as a government program has a positive impact on the farmer by improving their welfare through increasing wetland rice productivity.

Abstract

Pujiastuti et al, 2017. Production of Bacillus thuringiensis Spores in Agricultural Waste with Addition of Golden Snail Shell Powder and its Toxicity Against Spodoptera litura Fabr. (Lepidoptera: Noctuidae). JLSO 6(2):150-157.Armyworm or Spodoptera litura is an important pest on the cultivation of plants. Controlling by using biological agents such as Bacillus thuringiensis is an alternative to the use of chemical insecticides which cause a negative impact on insects and environment. B. thuringiensis-based bio insecticide can be reproduced by using agricultural waste with the addition of golden snail shell flour. The study was aimed to investigate the production of B. thuringiensis spores on agricultural waste media and the addition of golden snail shell flour and its toxicity to armyworm, as well. The research design was a completely randomized design with 10 treatments and 3 replications. Treatment were the media of agricultural waste: 50 mL coconut water, 50 mL of tofu liquid waste, 50 mL of rice wash water and mixture of three media (v/v/v, 1:1:1) with the addition of golden shell flour as much as 5 g and mineral salt of CaCl2, MgSO4, K2HPO4, KH2PO4. The results showed the production of bacterial spores ranged from 8.90x107 spores/mL to 9.51x107 spores/mL with the highest production in the mixed treatment of the three waste media (coconut water, tofu waste and rice laundry water). In this treatment the level of toxicity was 40% in larvae of armyworm. The weight of leaf feed consumed by armyworm at various treatments was ranged from 36.33 to 46.67 g/10 larvae. The addition of mashed shell flour to growth media of B. thuringiensis did not increase the number of spores.

Abstract

This research aimed to analyze the effectiveness ofthe Rural Agribusiness Development Program related to the performance of farmer group association at Lebanu in Marawola Sub District, Sigi Regency. It determined the differences in production and income level of the rice farming before and after receiving fund from the Rural Agribusiness Development Program at Lebanu, Sigi. Descriptive analysis was used to identify the effectiveness of the Rural Agribusiness Development Program and comparative analysis paired t-test to examine the differences in production and income of the rice farming before and after receiving the fund. The results showed that the performance of the farmer group association at Lebanu of Marawola is actually effective with a total score of 951 out of a maximum score of 1071. It indicates that the service and distribution of the funds is successful. Meanwhile, the comparison of production after and before receiving Rural Agribusiness Development Program was found that tcounted value is 11.264 >ttabel (2.010) at ? 5%. Similarly, the rice farmers income after receiving the rural agribusiness development program was found that tcounted value is 8.472 >ttabel (2.010) at ? 5%. The results indicate that there is a significant and positive increase on the production and income of the rice farming after receiving the funds of the rural agribusiness development program than before receiving it.
