The Effect of Fermented Rice Bran of The Silage of Cow’s Rumen with Different Storage Time on The Physical Quality, pH and Nutrient Content of Silage

Iyan Pramadana — 2024-03-31

This study, conducted from March to May 2023, aimed to assess the impact of fermented rice bran from cow rumen contents on silage quality, pH, and nutrient content with varying storage times. The experiment took place in Porame Village, Central Sulawesi Province, and Tadulako University's Feed Nutrition Laboratory. The study used molasses, rice bran, EM4, water, and cow rumen waste as materials. Employing a complete randomized design with a 2x3 factorial pattern, the study had 6 treatment combinations and 24 experimental units. Factors included fermented and unfermented rice bran ratios mixed with cow rumen content, and storage times (21, 25, and 30 days). Results from SPSS analysis indicated no significant interaction between fermented rice bran and storage time regarding physical quality and nutrient content. However, the pH of silage was significantly affected. Fermented rice bran (A2) led to a notable pH reduction compared to non-fermented rice bran (A1). In summary, this study concluded that while there's no substantial interaction effect on physical quality and nutrient content, pH measurements are impacted by the use of fermented rice bran.

Ground Infiltration in Various Land Uses in Kawatuna Sub- Watershed

Elvira Ahmad — 2024-03-31

The research was conducted in the Kawatuna Sub-watershed with the aim of studying the physical properties of the soil and knowing the infiltration rate of several land uses in the Kawatuna Sub-watershed. This study used the Horton equation formula and took soil samples for analysis at the Laboratory of Soil Science, Faculty of Agriculture, Tadulako University, Palu. The results showed that the physical properties of the soil greatly influenced the infiltration process, the highest organic matter was secondary soil 6.10%, dry land agriculture 4.50% and the lowest was shrubs 3.04%. Secondary forest soil textures are loam and dusty loam, dry land agriculture has sandy loam textures, and shrubs have loamy, sandy loam and dusty loam textures. In terms of physical properties of water content, dry land agriculture had the highest water content 21.48%, secondary forest 19.19% and shrubs the lowest 15.54%. The highest infiltration rate was secondary forest land (12.74 cm/hour) with fast criteria, dry land agriculture (7.80 cm/hour) medium fast category and shrub land (6.19 cm/hour) medium category.

Empowerment Strategies for Forest Farmer Groups (FFGs) in Honeybee Cultivation within the Dolago Tanggunu Forest Management Unit Area

Dewi Soekardjo — 2024-03-31

This research aims to empower and identify internal (strengths and weaknesses) and external (opportunities and threats) factors influencing the empowerment of Forest Farmer Groups (FFGs) in honeybee cultivation within the Dolago Tanggung Forest Management Unit, Central Sulawesi. The study was conducted from March to May 2023, involving 45 respondents from 3 FFGs, each comprising 15 members. Qualitative descriptive analysis and SWOT analysis with IFAS and EFAS matrices were employed. The results of the internal and external factor analyses revealed strengths such as training for FFG members and financial assistance, weaknesses including limited FFG members participating in training and difficulties in securing additional funds for maintenance costs. Opportunities encompassed government support and consumer trust in products, while threats comprised weather changes and underutilization of technology for information acquisition. The SWOT analysis placed the study in Quadrant 1, indicating support for an aggressive strategy leveraging strengths to seize opportunities. Strategies suggested involve enhancing relationships among government, FFGs, and partners, boosting honey production and quality, providing regular honeybee cultivation training, utilizing agricultural and information technologies for product marketing, and employing attractive packaging to enhance consumer appeal.

Community Social Capital in Community Forest Management in Poso Pesisir District

Moh. Isnain — 2024-03-31

In Indonesia, commercial management of community forests began several hundred years ago. This research aims to measure the level of social capital in community forest management, and analyze its influence on community forest performance. The research was carried out using a survey method. Two villages in one district were chosen purposively. Respondents were 60 people that randomly selected from each village. The results of the research reveal that the level of social capital of the two communities in community forest management is classified as different. High social capital has facilitated the revival of good community forest performance, which is characterized by high levels of community forest productivity, as well as continuing sustainable management of community forests, the benefits of regulations. fair management and cost efficiency of community forest management. Strong social capital drives better performance. This research concludes that community social capital in managing community forests in Toini Village is relatively high, while in Betania Village it is low. Considering the differences in social capital that exist in society, the author suggests the need to increase parties, especially the government, to support forest management through increasing roles, facilitating the expansion of social networks, and strengthening the implementation of rules to the community.

Physical and Chemical Quality of Rice Bran with the use of Noni (Morinda citrifolia) Leaf Extract as a Vegetable Preservative Ingredient

Ruslan Ruslan — 2024-03-31

The results showed that the interaction between the level of use of noni leaf extract and the treatment time was not significant (p>0.05) on the specific gravity and water content variables, but had a very large influence. significant effect (p<0.01) on the variables fat content, amount of feroxide and antioxidants). The specific gravity of the use of BHT preservative gives a value that is no different from the use of noni leaf extract vegetable preservative, the same thing also happens with the long storage treatment. The higher use of noni leaf extract in rice bran can significantly reduce the water content, crude fat and ferroxide levels, but can increase the antioxidant content. The conclusion from the results of this research is that the physical and chemical quality of rice bran can be maintained by using 0.03% noni leaf extract with a storage time of up to 42 days.

Supervision and Control of Fisheries Resources in Illegal Fishing Activities in Central Sulawesi (Case Study at WPPNRI 713)

Arwansa Arwansa — 2024-03-31

The main objective of this study is to know the supervision and law enforcement in the management of fisheries resources in WPPNRI 713, Central Sulawesi Province. This research was conducted in September - October 2022. The sample used was a sample of the WPPNRI 713 Fishermen community in Donggala Regency. This study uses a qu(2024)alitative method. Data collection by means of sampling includes observation activities, in-depth interview techniques, questionnaires and documentation studies. Using Descriptive Qualitative data analysis method with percentage distribution tabulation. The results of the research show that the supervision of fish resource management in WPPNRI 713, especially in the province of Sulawesi, has not been maximized, the institutions have not been maximized, the FADs have not been arranged and while the use of fishing gear has shown compliance of around 50% more in accordance with laws and regulations.
