Abstract

Given paddy's status as a staple commodity and primary livelihood in Slogoretno Village, frequently experiencing yield reductions due to pest attacks, this community service activity aimed to educate and implement Integrated Pest Management (IPM) through the planting of refugia plants. The program involved the socialization of local-based refugia concepts, practical planting of perimeter refuge patterns on paddy demonstration plots, and the initiation of agrotourism. The results showed a significant increase in farmers' and the community's knowledge regarding ecological engineering techniques using flowering plants for paddy pest control. Furthermore, these demonstration plots have the potential to become agrotourism objects, which is expected to enhance local welfare and sustainably boost harvest productivity. The implementation of refugia affirms its effectiveness as an IPM innovation supporting sustainable agriculture.

Abstract

Kebonagung Sub-district, Sidoharjo District, Wonogiri Regency is the Wonoagung Wonogiri Organic Farming Association (PPOWW) location. Mitra is an organization engaged in organic rice and cattle cultivation. The conversion of bovine dung into organic fertilizer, particularly liquid fertilizer containing biological agents, is one of the waste elimination strategies employed to prevent environmental contamination. The nutrient content of organic fertilizer material sources varies. Organic fertilizer of high quality conforms to the Standard for Organic Fertilizers established by the Ministry of Agriculture of the Republic of Indonesia. Only some producers are aware of the standard quality requirements for organic fertilizer. It is necessary to analyze the nutrient content of organic fertilizer products to determine whether the quality of organic fertilizer is excellent. A preliminary survey of partner conditions, preparation of materials (organic fertilizer), and analysis of fertilizer content are among the activities performed. The C/N ratio of organic fertilizer is 8.41, and its pH is 7.6. The analysis results indicate that the Wonoagung Wonogiri Organic Agriculture Association's organic fertilizer products meet the liquid organic fertilizer quality standards. This condition demonstrates that the raw materials used in organic fertilizer production are of high quality and that the appropriate procedures have been followed. Adding biological agents to the production of organic fertilizer can enhance the quality of the finished product.

Abstract

In an effort to solve the P availability issue in Inceptisols, fermentation is one method used to enhance the quality of liqiuid organic fertilizer (LOF) made from Moringa (Moringa oleifera). The type and concentration determine the effectiveness of LOF on nutrient uptake and plant yields. This study aims to evaluate the impact of LOF types, concentrations, and their interactions on P uptake and rice grain yield in Inceptisols. The research was conducted in a greenhouse using a completely random design (CRD) with two factors. The first factor is the type of LOF, consisting of two levels, i.e., fresh and fermented Moringa extract. The second factor is the LOF concentration, with four levels (i.e., 0, 20, 40, 60, and 80 ml/l) and three replications. Data analysis using ANOVA, DMRT, and correlation. The study revealed that the interaction between LOF types and concentrations affects P uptake. The highest P uptake shown by fermented Moringa with a concentration of 60 ml/l was 20.02 mg/plant and 40 ml/l was 18.73 mg/plants., or 1.5 times higher than the control. Grain yield was not affected by type, LOF concentration, or interaction. Fermented Moringa has good potential as LOF, while the effect on grain yield needs further research.

Abstract

The characteristics of indigenous bacterial isolates in cocoa farms differ based on the study's location and methodology. More research is required to comprehend these bacterial isolates' diversity and features completely. This study intends to assess the cellulose-degrading capacity of bacterial isolates from cocoa plantations in Meko Village, Central Sulawesi. The shape of the bacterial colony, the shape of the colony's edge, elevation, colony size, color, and texture are considered during macroscopic morphological identification and microscopic morphological identification after gram stain. Afterward, gram stains the bacteria to determine the type of cell wall. Hydrolysis capacity was then identified macroscopically by observing colony shape, colony periphery, colony color, colony appearance and height, and hydrolysis capacity on media in a petri dish (HC). Upon microscopic examination of cell shape and bacterial wall type (Gram-positive and gram-negative). Based on the research findings and identification of bacteria capable of degrading cellulose in cocoa soil, it can be inferred that among the 28 examined isolates, six isolates have the greatest HC index values in KL62 isolates. In contrast, GL66, KL23, and KL62x isolates have medium HC index values.

Abstract

This study aimed to analyze the influence of rehabilitation length process of the ex nickel mining land on soil pH, SOM, population and soil microbial distribution in East Halmahera, North Maluku, Indonesia. Purposive sampling method was taken under completely randomized design (CRD) with variation of rehabilitation length process: 0, 2, 4, 6, and 8 years. The parameter included soil pH, SOM, population and soil functional bacteria. Data was analyzed using ANOVA and continued by Duncan Multiple Range Test (DMRT) at 5% error level. The result showed the length of rehabilitation process can reduce soil pH, increasing bacteria and fungi population. Four years of rehabilitation process in 2020-Nancy with special treatment of intensive watering resulted the best soil quality characterized by soil pH 6.48, SOM 4.03%, bacteria population of 85 × 10¹ CFU/g, fungi population of 7 × 10¹ CFU/g, non-symbiotic nitrogen-fixing bacteria of 7.0 × 10¹ CFU/g, phosphate-solubilizing bacteria of 0.5 × 10¹ CFU/g, potassium-solubilizing bacteria of 1.0 × 10¹ CFU/g, and proteolytic bacteria of 3.0 × 10¹ CFU/g. The rehabilitation length of 4 years with intensive watering is recommended to provide nutrient and soil microbial on ex-nickel mining rehabilitation. Keywords: Bacteria, Fungi, Nickel, pH, SOM.
