Abstract

This study aims to determine the inhibitory ability of antagonistic fungi from the rhizosphere of pepper (Piper nigrum L.), betel nut (Piper bettle L.) and Bawang Suna (Allium cinense G.Don.) against Fusarium oxysporum capsici which causes damping off disease and its effectiveness as a seed coating against damping off disease in chili seedlings. The research was carried out in the laboratory and experimental garden of the Department of Agricultural Cultivation, Faculty of Agriculture, UPR. Testing the antagonistic inhibition of F.o.capsici in vitro, where the antagonistic fungus with the highest inhibition from each plant rhizosphere was used as a seed coating for chili seeds to determine its effectiveness in suppressing damping off disease on seedlings. The results of the study obtained nine antagonist fungi with very good inhibition against the pathogen F.o.capsici in vitro ranging from 70.36 – 77.74%. Three types of antagonistic fungi that are used as active ingredients in seed coatings are Gliocladium sp. from pepper rhizosphere (73.53% inhibition), Penicillium citrinum from betel rhizosphere (77.74% inhibition), and Trichoderma harzianum from suna onion rhizosphere (70.83%). The seed coating treatment with active ingredients from three types of biological agents significantly reduced the intensity of damping off disease (0%) compared to the control (23.75%). Control effectiveness reaches 100% with very good category. Seed coating with active ingredients of T. harzianum and Gliocladium sp was able to increase plant height by 34.06% and 43.11%, respectively, but there was no significant difference in increasing the number of leaves. Seed coating treatment with biological agents effectively protects seeds and plant seedlings from attack by pathogens F.o. capsici through mechanisms such as antibiosis, parasitism and competition, besides that rhizosphere fungi can induce plant resistance and produce growth regulators which can increase the growth of chili seedlings. It is hoped that in the future the seed coating treatment added with biological agents can replace the use of chemical pesticides in controlling soil-infected diseases

Abstract

Poverty alleviation and reduction must be done through development programs, one of which is through BUMDes empowerment. The existence of BUMDes is directed at community development policies aimed at overcoming poverty in the community. This research aims to determine the institutional effect of village-owned enterprises (bumdes) on household poverty in donggala district during the co-19 pandemic. This research was conducted in Donggala Regency, Sulawesi Province The method of determining the research location was carried out deliberately. The data analysis used in this research is qualitative analysis and quantitative analysis. The results showed that in real terms the variables of income, consumption expenditure, the presence of BUMDes and the influence of Covid-19, had an effect on household poverty in Donggala Regency. The variables of age and number of household members have no effect on poverty. Keywords:, BUMDes, Poverty, Covid 19

Abstract

Cocoa replanting with intercrops is a strategy for sustainable cocoa development. Cocoa replanting is expected to impact productivity and production quality and increase selling prices positively. However, there are still many farmers who are reluctant to replant due to concerns about losing sources of income and financing difficulties. The study analyzed the cost and income structure of various replanting models. Based on the survey, there were 88 cocoa farmers as respondents, 51 who replanted and 37 who did not. Through the analysis of cost and income structures, it is known that replanting cocoa can be a rational option for farmers who want to increase their income because replanting can increase the productivity of cacao. In addition, the income from the intercrops has also been shown to replace the income of the cocoa lost at the time of the replanting. Analyzing the partial profit balance shows that bananas and chili are profitable crops to plant as intercrops on cocoa groves when replanting. For farmers who plant bananas as an intercrop, the income from bananas can cover unloading costs, seed costs and cocoa planting costs within one year

Abstract

Salawati District, as one of the agricultural centers in Sorong Regency, has 82.43% of its population employed in the agricultural sector. Over time, the community faces various challenges threatening the food supply and agricultural sustainability. The success of soil and water conservation practices heavily relies on the participation and contribution of local communities. This research aims to identify adopted soil and water conservation practices, assess the level of knowledge regarding these practices, and evaluate their impact on sustainable food production. The research design combines qualitative and quantitative approaches. Results indicate that the local community's knowledge stands at 72.86%, with 82.86% implementing soil and water conservation practices in agricultural cultivation processes. The primary motivation for applying conservation practices is to enhance agricultural yields (70%), followed by environmental sustainability concerns (15.71%) and personal motivations (14.29%). Challenges faced include a lack of resources (34.29%), weather uncertainties (30%), insufficient knowledge about conservation practices (22.86%), and time constraints (12.86%). Information sources for implementing soil and water conservation practices include other farmers (51.43%), the internet or social media (37.14%), local agricultural experts (8.57%), and agricultural training (2.86%). Farmer groups serve as the primary support system for implementing soil and water conservation practices, with 100% of the local community having a more sustainable outlook on increasing local food production. Sustainable agricultural systems can be achieved by improving land quality, ultimately enhancing sustainable food production and achieving food security.

Abstract

The production of fish protein hydrolysate from common pony fish yields a fraction rich crude fish oil as a by-product. To utilize this by-product, refining is necessary to obtain common pony fish oil. This research aims to use a fraction rich crude fish oil from fish protein hydrolysate by-products to obtain fish oil and to determine the optimal conditions for the refining process using the response surface method (RSM) in the degumming, neutralization, and bleaching processes. The experimental design used was the Box–Behnken design, with the responses used to determine the optimum conditions at the degumming stage were water content and total dissolved solids. The response used to determine the optimum conditions at the neutralization stage was the refining factor, and at the bleaching stage was color (L, a*, b*). Parameters studied for each purification process include heating temperature (50-80°C), contact time between fraction rich crude fish oil with auxiliary materials (10-20 minutes) and the length of time for centrifugation (5-15 minutes) with a rotation speed of 10,062 G. The optimal conditions obtained in the degumming, neutralization, and bleaching processes for heating temperature, contact time between fraction rich crude fish oil with auxiliary materials, and centrifugation time, respectively,  were 50°C, 10 min, 5 min; 50°C, 20 min, 5 min; and 80°C, 10 min, 15 min. Verification of the optimum conditions resulted in a free fatty acid value of 8.25% ± 0.01%, an acid value of 1.87 ± 0.02 mg KOH/g oil, a peroxide value of 1.04 ± 0.01 meq/Kg, an anisidine value of 11.11 ± 0.01 meq/Kg, a total oxidation value of 13.21 ± 0.01 meq/Kg and water content 6.052 ± 0.02 %. These results indicate a reduction in free fatty acids, acid number, peroxide number, anisidine number and water content by 66%, 90%, 73.5%, 61%, 63%, and 92% respectively. Our results showed that the purified fraction rich crude fish oil has met the SNI standards in parameter acid number, peroxide number, iodine number, anisidine number, and total oxidation value. The purification process that has been carried out can improve the quality fraction rich crude fish oil, but further processing still needs to be carried out to reduce water content and free fatty acid value
