Optimizing Forest Utilization through Multi-Forestry Enterprises at PBPH PT Kiani Lestari
type: item
description: This study aims to analyze the causes of low HHK-TA production, identify alternatives and strategies for optimizing area utilization through a multi-forestry business approach, and evaluate the feasibility of business development in the PBPH area of ​​PT Kiani Lestari. The study was conducted in East Kutai Regency, East Kalimantan using fishbone analysis to identify root causes, SWOT to formulate management strategies, Analytical Hierarchy Process (AHP) to determine business alternative priorities, Cost-Benefit Analysis (CBA) and Payback Period (PP) to assess financial feasibility, and spatial interpretation for work area planning. The research results indicate that low production is influenced by limited human resources, production equipment, non-capacity-based planning methods, weak monitoring, and environmental and regulatory factors. AHP analysis indicates that plantation forests (HT) are the top priority alternative with a value of 0.41, followed by silvopasture (0.34) and HHK-TA (0.25), with a Consistency Ratio (CR) of 0.027. However, CBA results indicate that only silvopasture is financially viable with an NPV of IDR 4,061,000/ha, a BCR of 1.28, an IRR of 14.6%, and a 4-year PP period. This research demonstrates that a multi-enterprise forestry approach integrating HT, silvopasture, and HHK-TA can be a more adaptive strategy for increasing productivity, economic value, and the sustainability of forest management. Keywords: feasibility analysis, sustainable forestry, multi-enterprise forestry, forest utilization optimization, silvopasture. Abstrak.

Analysis of Antioxidant Activity, Protein Content, and Organoleptic Properties of Functional Set Yoghurt Supplemented with Pumpkin Puree and Liquid Palm Sugar.
type: item
description: This study evaluated the potential of pumpkin puree (Cucurbita moschata) and liquid palm sugar (Arenga pinnata Merr.) as local bioactive ingredients for developing functional set yoghurt. A 4 × 4 factorial randomized design with three replications was employed, comprising four levels of pumpkin puree (0, 4, 8, and 12%) and four levels of liquid palm sugar (0, 4, 8, and 12%). Antioxidant activity (assessed using the DPPH method), protein content, and sensory acceptance of taste and color were analyzed. The results demonstrated that the combined addition of pumpkin puree and liquid palm sugar significantly enhanced the antioxidant capacity, as indicated by a decrease in IC50 from 103.94 ± 2.18% in the control to 39.38 ± 0.79% in yoghurt containing 12% pumpkin puree and 12% liquid palm sugar. The highest taste acceptance was observed in yoghurt with 8% pumpkin puree and 12% liquid palm sugar, whereas protein content (4.27–5.00%) and color acceptance were not significantly affected by the treatments. These findings indicate that incorporating pumpkin puree and liquid palm sugar can improve both the functional and sensory properties of set yoghurt without compromising protein quality, highlighting the potential of indigenous ingredients as natural antioxidant fortificants and sweeteners in functional dairy product development.

The Effect of Various Concentrations of Antagonistic Rhizobacteria on Germination and Seedling Vigor of Colletotrichum-Infected Chilli Seeds
type: item
description: Red chili pepper (Capsicum annuum L.) is an important horticultura commodity in Indonesia. However, chili production is often constrained by anthracnose disease caused by Colletotrichum sp., which can infect seeds and reduce seed viability and vigor. The use of antagonistic rhizobacteria from chili rhizosphere is considered a potential biological control method to suppress pathogen infection and improve seed quality. This study aimed to determine the effect of different concentrations of antagonistic rhizobacteria on the viability and vigor of chili seeds infected with Colletotrichum sp. The experiment used a non-factorial completely randomized design consisting of five treatment level (control, 10⁶, 10⁸, 10¹⁰, and 10¹² cfu/ml). The results showed that treatment with antagonistic rhizobacteria had a positive effect in suppressing Colletotrichum sp. infection and improving seed performance. The treatment with a concentration of 10¹² cfu/ml was able to minimize disease incidence to 15.00%, increasing maximum growth potential to 99.00%, increased germination percentage to 94.00%, vigor index to 89.00%, and germination uniformity to 94.00%. The highest growth rate was obtained in the 10⁶ cfu/ml treatment, reaching 14.05%. These findings confirm that antagonistic rhizobacteria are effective as environmentally friendly biocontrol agents for improving the viability and vigor of chili seeds infected with Colletotrichum sp. Keywords: chilli seeds, antagonistic bacteria, Colletotrichum sp., viability, vigour, biological control

Fumigation-Based Agricultural Sanitation Technology in the Production Chain of Broiler Hatching Eggs
type: item
description: Broiler parent stock production units play an important role in the poultry agroindustry chain because they produce hatching eggs as the main source for day-old chick production. Hatching eggs are biological products that are highly susceptible to microbial contamination from the farm environment until they enter the hatchery. Therefore, the implementation of sanitation and fumigation is necessary to maintain hatching egg quality and strengthen the biosecurity system in poultry production. This study aimed to describe the application of fumigation as a biosecurity-based sanitation technology in a broiler parent stock production unit located in Mekarwaru Village, Gantar District, Indramayu Regency, West Java. The study was conducted from September to November 2024 using a descriptive qualitative method. Data were collected through direct observation, guided interviews, and field documentation. Observations focused on the fumigation of closed-house poultry houses, fumigation of hatching eggs in fumigation boxes, sanitation of egg transport vehicles, fumigation of hatching eggs in the egg storage room, the use of fumigant materials, and the application of personal protective equipment. The results showed that fumigation was applied in multiple layers at critical biosecurity points. Poultry house fumigation was carried out after sanitation procedures to reduce microbial contamination in the production environment and to interrupt the contamination cycle between production periods. Hatching egg fumigation was conducted in farm fumigation boxes and in the egg storage fumigation room to reduce the risk of eggshell contamination before the eggs were transported to the hatchery. Sanitation of egg transport vehicles supported the continuity of biosecurity between production units. The use of fumigants was adjusted according to room volume, fumigation duration, gas residue control, and worker safety requirements. In conclusion, fumigation applied in the broiler parent stock pr…

Effectiveness Test of Combined Extract Concentrations from Mature and Immature Physic Nut Seeds (Jatropha curcas) on the Mortality of Golden Apple Snail (Pomacea canaliculata)
type: item
description: The golden apple snail (Pomacea canaliculata) is a major pest causing significant damage to rice plants, particularly at the early vegetative stage. The use of chemical pesticides for its control poses negative environmental impacts, thus environmentally friendly alternatives such as botanical pesticides are needed. Physic nut (Jatropha curcas) seeds contain bioactive compounds with pesticidal properties. This study aimed to evaluate the effectiveness of combined mature and immature physic nut seed extract on snail mortality, weight loss, and morphological changes, and to determine the most effective concentration. The experiment used a Completely Randomized Design (CRD) with five treatments: control (0 g/L), 5 g/L, 10 g/L, 15 g/L, and 20 g/L, each with three replications. The results showed that the extract significantly affected all observed parameters. The highest mortality (93%) and weight loss (28.04%) were observed at 20 g/L. Morphological changes included reduced activity, slower response, operculum opening, and eventual body extrusion from the shell leading to death. Higher extract concentrations resulted in greater mortality, weight reduction, and morphological damage. Physic nut seed extract has strong potential as an effective and environmentally friendly botanical pesticide. Keywords: botanical pesticide, golden apple snail, Jatropha curcas, mortality, morphology

Effect of Plant Growth Regulator Types and Planting Media on the Growth Performance of Moringa ( Moringa oleifera L.) Stem Cuttings
type: item
description: Moringa (Moringa oleifera L.) is known as the tree of life because of its high nutritional content and health and economic benefits. However, moringa cultivation in Indonesia remains suboptimal, mainly due to the limited availability of quality seedlings. Vegetative propagation through stem cuttings can produce uniform seedlings, but its success depends on plant growth regulators and planting media. This study aimed to determine the effects of plant growth regulators and planting media on the growth of moringa stem cuttings. The experiment was conducted in a screen house at SITANDU, Banten, from October to December 2025 using a factorial Randomized Block Design with two factors. The first factor was plant growth regulator type: control, Rootone-F 0.03%, shallot extract 60%, mung bean sprout extract 60%, and young coconut water 60%. The second factor was planting medium: rice husk charcoal + soil, compost + soil, and cattle manure + soil, each at a 1:1 ratio. The results showed that Rootone-F 0.03% improved several growth parameters, particularly shoot length at 6 WAP, leaf number, and root length. Rice husk charcoal and soil were the best media for shoot and root growth. The combination of Rootone-F 0.03% and rice husk charcoal + soil produced the best response, particularly in shoot number, leaf number, and root length.

Response of Vegetative Growth of Nutmeg (Myristica fragrans Houtt.) at 3 Months of Age to the Application of Biofertilizer Based on Black Soldier Fly (BSF) Maggots
type: item
description: This study aimed to evaluate the vegetative growth response of three-month-old nutmeg plants (Myristica fragrans Houtt.) to the application of a biofertilizer derived from Black Soldier Fly (BSF) maggot frass. The biofertilizer was produced through the bioconversion of organic waste and enriched with functional microorganisms such as Trichoderma and Azotobacter, which play a critical role in enhancing soil fertility and promoting early plant development. The experiment was conducted over three months at a nutmeg plantation in Afe Taduma, Ternate City, with observations carried out biweekly. Measured parameters included plant height, number of leaves, stem diameter, and canopy length as indicators of vegetative growth. Results showed that the application of BSF maggot-based biofertilizer significantly improved all vegetative growth parameters. The treated plants reached an average height of 88.2 cm, produced 93 leaves, and exhibited a stem diameter of 120 mm (±1.33 mm) and a canopy length of up to 580 cm (±8.80 cm) by the final observation. These findings suggest that BSF maggot-based biofertilizer is a promising organic input for supporting the early vegetative phase of nutmeg cultivation. Furthermore, its use contributes to reducing dependency on chemical fertilizers and promotes a more sustainable and environmentally friendly agricultural system.

Concentration Level Test of Antagonistic Bacteria from Oil Palm Rhizosphere on Viabiliy and Vigor of Chili Seeds Infected with Colletotrichum sp.
type: item
description: Chili production in Indonesia has declined due to anthracnose disease caused by Colletotrichum sp., which can infect plants from the seedling stage through harvest, thereby reducing seed viability and vigor. This study aimed to determine the optimal concentration of antagonistic rhizobacteria from the oil palm rhizosphere to improve the viability and vigor of infected chili seeds. The experiment used a Completely Randomized Design (CRD) with five treatments: BRS0 (water control + Colletotrichum sp.), BRS1 (10⁶ cfu/ml), BRS2 (10⁸ cfu/ml), BRS3 (10¹⁰ cfu/ml), and BRS4 (10¹² cfu/ml), with five replicates. The results of the study indicate that the application of rhizobacteria has a significant effect on seed viability and vigor. The BRS3 treatment (10¹⁰ cfu/ml) showed better performance by increasing maximum growth potential (91.20%), germination percentage (76.00%), germination speed index (12.62%), germination uniformity (58.00%), vigor index (45.60%), and reducing Colletotrichum sp. infection by 10.40% compared to the control. These findings indicate that rhizobacteria have potential as a biological control agent to enhance seed quality under pathogen stress.

Effectiveness of Ketapang Leaf Extract (Terminalia Cattapa L.) As a Bioherbicide Against The Growth of Purple Nutsedge (Cyperus Rotundus L.)
type: item
description: Purple nutsedge (Cyperus rotundus L.) is a problematic weed in agricultural land because it has high adaptability and strong competition with cultivated plants for water, nutrients, light, and growing space. The continuous use of synthetic herbicides may cause environmental problems and leave residues in soil and plants. Therefore, plant-based bioherbicides are needed as a more environmentally friendly alternative. Ketapang leaves (Terminalia catappa L.) contain allelochemical compounds that have the potential to inhibit weed growth. This study aimed to evaluate the effect of ketapang leaf extract as a bioherbicide in suppressing the growth of purple nutsedge. The study used a non-factorial Completely Randomized Design consisting of five treatments, namely distilled water as control, 5%, 20%, 35%, and 50% ketapang leaf extract, with four replications. The observed parameters were plant height, number of leaves, plant dry weight, phytotoxicity, and root length. The data were analyzed using analysis of variance at the 5% level, followed by the Least Significant Difference test when the treatment effect was significant. The results showed that ketapang leaf extract significantly affected plant height at 27 and 30 days after planting, number of leaves at 30 days after planting, plant dry weight, and root length, but did not significantly affect phytotoxicity. Based on the Least Significant Difference test, the inhibitory effect was more evident at medium to high concentrations. The 20%, 35%, and 50% concentrations showed relatively comparable effects on plant height at the later observation stages, while the 35% and 50% concentrations showed comparable effects on plant dry weight and root length. These results indicate that ketapang leaf extract has potential as a plant-based bioherbicide for suppressing purple nutsedge growth, especially at medium to high concentrations. Keywords: bioherbicide, ketapang leaf extract, purple nutsedge, weed growth.
