Abstract

 Trichoderma brevicompactum indigenous to Gorontalo is a potential biological control agent that plays an important role in plant disease management and agricultural waste utilization. The availability of cost-effective and environmentally friendly growth media is a key factor in supporting the production of fungal inoculum. This study aimed to describe the growth response of Gorontalo indigenous T. brevicompactum on agricultural waste-based media, namely cassava peel extract and coffee peel extract, in comparison with Potato Dextrose Broth (PDB) as a control medium. The study was conducted using a descriptive approach at the Laboratory of Plant Pests and Diseases, Faculty of Agriculture, Universitas Negeri Gorontalo. The observed parameters included changes in the physical properties of the media (temperature, pH, and color), mycelial biomass, relative growth rate (RGR), absolute growth rate (AGR), and conidial density during the incubation period. The results showed that, descriptively, cassava peel extract exhibited a higher tendency in RGR and AGR values than the control medium and coffee peel extract, particularly during the mid-incubation phase. In contrast, coffee peel extract showed a relatively lower growth response, especially at the later incubation stage. Conidial density increased over time in all media, with the highest values observed in the control medium, followed by cassava peel extract and coffee peel extract. Overall, cassava peel and coffee peel wastes have potential as alternative growth media for T. brevicompactum, with cassava peel extract demonstrating a more favorable growth tendency.

Abstract

The increasing use of synthetic polymer-based plastics derived from non-renewable resources has caused serious environmental and health problems. Therefore, the development of bioplastics based on natural polymers is considered a sustainable solution. This study aimed to isolate cellulose from lontar fruit fiber (Borassus flabellifer Linn.) and to evaluate its potential application as a raw material for bioplastic production. Lontar fruit fiber was subjected to alkaline treatment using NaOH, followed by bleaching with H₂O₂ and acid hydrolysis using H₂SO₄. The isolated cellulose was characterized in terms of yield, moisture content, and functional group identification using Fourier Transform Infrared (FTIR) spectroscopy. The results showed that the final cellulose yield reached 45.67%, indicating the dominance of the cellulose fraction after significant removal of hemicellulose and partial lignin. FTIR analysis confirmed the presence of characteristic cellulose functional groups, including hydroxyl (–OH), C–H stretching, and β-1,4-glycosidic (C–O–C) bonds, while lignin-related absorption bands were observed with very low intensity. The isolated cellulose was subsequently applied in bioplastic formulation using gelatin and glycerol as plasticizers. The resulting bioplastic exhibited homogeneous appearance, good elasticity, and low brittleness. These findings demonstrate that cellulose derived from lontar fruit fiber has strong potential as an environmentally friendly bioplastic raw material and supports the valorization of local biomass waste from dryland ecosystems.

Abstract

Ethnobotany of medicinal plants is a form of interaction between local communities and their environment. Local wisdom in the use of medicinal plants is also shaped by the ecosystem of the local area, whether it is coastal areas, mountains, forests, deserts and so on. Raam Island is one of the islands in the Sorong Islands District of Sorong City.  The lack of support for health facilities is one of the reasons why the people of Raam Island use local plants for first aid if they are attacked by disease.  Research data or written information about ethnobotany and local wisdom of the people of Raam Island, Archipelago District have not yet been found, so this research is expected to provide scientific information to the community, government, related agencies and all parties who need it.  The method used in this research is exploratory descriptive with survey methods and semi-structural interview techniques. The selection of respondents at this interview stage was carried out using the snowball sampling method, namely a technique for selecting respondents based on key informant recommendations.  The results of the research found 41 types of plants used as medicine, 85% of the parts used were the leaves.  As a tourism development area, it is important to increase attention to local wisdom in the use of medicinal plants on Raam Island. Keywords: Ethnobotany, medicinal plants, Raam Island

Abstract

Rice is the main food crop commodity because the majority of the Indonesian population consumes rice as a staple food. Using superior seeds can help meet the increasing demand for rice due to population growth. There are local superior seeds that have not been utilized optimally by farmers in Lampung Province, namely MSP rice seeds. Since 2022, farmers in North Lampung Regency, precisely in North Kotabumi District, have been cultivating MSP rice. However, not all farmers cultivate MSP rice. The purpose of this study was to determine the comparison of production between MSP and non-MSP rice, to determine the comparison of income levels of MSP and non-MSP rice farming, and to determine the feasibility of MSP rice farming. The number of respondents was 60 farmers, namely 30 MSP rice farmers and 30 non-MSP rice farmers. Data analysis method uses income calculation using revenue structure and cost structure. Feasibility analysis of farming business uses R/C ratio. MSP rice production is lower compared to non-MSP rice production, which is 3,996.81 kg/ha for MSP rice and 4,113.44 kg/ha for non-MSP rice farming. The profit of MSP rice farming is higher than the profit of non-MSP rice farming both on cash costs and on the basis of calculated costs. The profit on cash costs of MSP rice is IDR 32,652,337.58/hectare and IDR 30,462,768.96/hectare for non-MSP rice. The profit on the basis of calculated costs is IDR 26,913,039.49/hectare for MSP rice farming and IDR 24,486,329.15/hectare for non-MSP rice farming. Based on the R/C ratio analysis, MSP rice farming is feasible to be pursued because the R/C ratio value is >1, which is 3.20 R/C ratio of cash costs and 2.31 R/C ratio of calculated costs. So that MSP rice farming has the potential to increase the income of rice farmers in North Kotabumi District.

Abstract

Dependence on synthetic pesticides for horticultural pest control has caused environmental damage and pest resistance, especially in upstream watershed areas. This study evaluated the effectiveness of the entomopathogenic fungus Beauveria bassiana for controlling major insect pests on long bean (Vigna unguiculata sesquipedalis) and shallot (Allium ascalonicum) and its indirect effects on vegetative growth. Field trials in Mojokerto Regency (June–September 2025) used a randomized block design with one factor: B. bassiana concentration (A0 = control, A1 = 106 spores L-1, A2 = 107 spores L-1, A3 = 108 spores L-1), each with five replications. Primary observations recorded pest incidence and infection by B. bassiana; supporting measurements were plant height and leaf number at 14, 21, 35, and 42 days after planting. Treatments A2 and A3 produced significantly higher pest infection rates identified in Coleoptera, Lepidoptera, and Hemiptera by characteristic white mycelial sporulation compared with the control. Reduced pest pressure in these treatments corresponded with significant increases in plant height and leaf number for both crops. Results indicate that B. bassiana at 107–108 spores L-1 is an effective biocontrol agent against multiple pest orders and can indirectly enhance vegetative vigor, supporting its integration into environmentally friendly IPM programs.

Abstract

One environmentally friendly solution for managing household organic waste is converting it into Liquid Organic Fertilizer (LOF), which contains essential nutrients for plant growth. LOF not only improves soil fertility but also has the potential to serve as an alternative nutrient source in hydroponic systems, which are increasingly popular in urban agriculture. Since chemical fertilizers such as AB-Mix are relatively expensive, LOF offers a more economical and sustainable option, although its effectiveness and optimal concentration still require further evaluation. The objectives of this study were: (1) to determine the effect of household-waste-based LOF application on the growth of pak choi in a hydroponic system, (2) to determine the optimal concentration of household-waste-based LOF for pak choi growth in a hydroponic system, and (3) to evaluate the effectiveness of household-waste-based LOF as a substitute nutrient solution for pak choi growth in hydroponics. The research was arranged in a completely randomized design with four treatments, namely P0 = 100% AB-Mix (5 ml/L AB-Mix); P1 = 50% AB-Mix + LOF (2.5 ml/L AB-Mix + 5 ml/L LOF); P2 = 25% AB-Mix + LOF (1.25 ml/L AB-Mix + 5 ml/L LOF); and P3 = LOF (5 ml/L LOF). The observed variables included plant height, number of leaves, leaf greenness, fresh shoot weight, and fresh root weight. Based on the 5% Duncan test, the treatments showed significant differences in all observed variables. Treatment P0 produced the best response and was significantly different from the other treatments. Treatment P1 resulted in higher growth than P2 and P3, although statistically it was still significantly different from P0. Nevertheless, P1 demonstrated the ability to substitute AB-Mix nutrients by up to 50%.

Abstract

The split gill mushroom (Schizophyllum commune) is an edible fungus that can be readily identified by its distinctive morphology and has considerable potential for development as a food source and a producer of bioactive compounds in Indonesia. Consequently, the establishment of an efficient propagation method through pure culture is essential. This study aimed to isolate S. commune and to evaluate its mycelial growth on different pure culture media. Isolation was conducted using a tissue culture technique from healthy and fresh fruiting bodies. The culture media evaluated were Potato Dextrose Agar (PDA), rice washing water medium, coconut water medium, rice bran medium, and corn boiling water medium. Mycelial growth rate, radial growth diameter, and mycelial morphological characteristics were used as growth parameters. The results indicated that the type of culture medium significantly influenced the mycelial growth of S. commune. PDA, rice washing water, and rice bran media supported the highest and most uniform mycelial growth. Mycelia grown on PDA and rice bran media exhibited a whitish-yellow coloration, dense and uniform growth, and a cotton-like texture. These findings suggest that both conventional and alternative media derived from locally available resources can effectively support the pure culture of S. commune, offering potential for more cost-effective and sustainable cultivation practices.

Abstract

Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's strategic plantation commodities that contributes significantly to the national economy, especially in North Sumatra. The high productivity of oil palm plants is greatly influenced by cultivation management and pest control factors. One of the main pests that often causes significant losses in oil palm plantations is rats, which attack fresh fruit bunches (FFB) and have the potential to reduce both the quantity and quality of the harvest. Therefore, an effective, efficient, and sustainable rat pest control strategy is needed. This study aims to determine the effectiveness of using the rodenticide Erkatril in suppressing the rat population and reducing the level of attacks on oil palm fruit, so that it can be used as a basis for consideration in rat pest management in oil palm plantations. The study was conducted using a completely randomized design (CRD) consisting of three treatments of Erkatril rodenticide application frequency and five replicates. The parameters observed included rat population, percentage of fruit damage, rat mortality rate, and fresh fruit bunch productivity. The observation data were analyzed using Analysis of Variance (ANOVA) to determine the effect of treatment on the parameters observed. If the analysis results showed significant differences, the testing was continued with the Least Significant Difference (LSD) test at a 5% confidence level. The results showed that the frequency of Erkatril rodenticide application had a very significant effect on reducing the rat population, fruit attack rate, rat mortality, and oil palm fresh fruit bunch productivity. Treatment E3, which involved three applications of rodenticide, was the best treatment because it reduced the rat population to the lowest level, significantly reduced the percentage of fruit attacks, increased rat mortality, and produced the highest fresh fruit bunch productivity compared to other treatments. These findings indicate that the use of Erkatril rodenticide with the appropriate application frequency can be an effective rat pest control strategy to increase oil palm productivity.
