Abstract

Entomopathogenic fungi are fungi that can cause death to insect pests. Some reports state that entomopathogenic fungi are endophytic or can grow in plant tissue and are positive for plant growth and produce phenol substances that insects do not like. The study aims to determine whether the formulation of entomopathogenic fungi Metharizium anisopliae (Metchnikoff) Sorokin and Beauveria bassiana (Bals.-Criv.) Vuill given to pre-nursery oil palm seedlings can help increase growth and resistance to pests and plant diseases. The study used factorial RAK with 3 replications and 2 factors, namely M. anisopliae fungus (M) with 4 levels: M0 = 0 g (control), M1 = 5g, M2 = 10g, and M3 = 40g, and B. bassiana fungus (B) with 4 levels namely: B0 = 0g (control), B1 = 5g, B2 = 10g, and B3 = 40g. The research resultsshowed that sprouts could grow into seedlings well, with an average third leaves appearing at week 12 after planting. The results of ANOVA analysis showed that the treatment factor of M. anisopliae and B. bassiana fungus gave an effect that was not significantly different on the parameters of the number of leaves, plant height, stem diameter, leaf length, number of leaf spots, leaf spot area, number of insect bites, insect bite area, plant length, crown wet weight, crown dry weight, root wet weight, root dry weight and root crown ratio. In other words, adding various doses of mixed formulation of M. anisopliae and B. bassiana did not provide a response to trigger plant growth and prevent the undesirable effects of insects. There are suggested that the two fungi are already in the oil palm seedling tissue as endophytes but until the 12th week, they have not shown any effect as a growth promotor or preventive effect the seddling tissue not liked by insects.

Abstract

Biomass Analysis of Mucuna bracteata DC Due to the Application of Coffee Husk Waste as an Organic Nutrient Source. Mucuna bracteata DC is a cover crop that plays a crucial role in soil conservation and soil fertility improvement. This study aims to analyze the effect of liquid organic fertilizer (LOF) derived from coffee husk waste on the biomass growth of Mucuna bracteata DC, particularly in terms of fresh shoot weight, fresh root weight, dry shoot weight, and dry root weight. The research was conducted at Jalan Kuali No. 50, Medan Petisah District. The experiment was designed using a Completely Randomized Block Design (CRBD) with a single-factor treatment consisting of seven LOF dosage levels: K0 (no treatment), K1 (5 mL/polybag), K2 (10 mL/polybag), K3 (15 mL/polybag), K4 (20 mL/polybag), K5 (25 mL/polybag), and K6 (30 mL/polybag), with four replications, totaling 28 experimental plots. The results showed that the application of coffee husk LOF significantly affected the biomass growth of Mucuna bracteata DC. The highest fresh shoot weight (9.51 g) and dry shoot weight (2.14 g) were recorded in treatment K6 (30 mL/polybag), whereas the highest fresh root weight (2.29 g) and dry root weight (0.32 g) were observed in treatment K5 (25 mL/polybag). Higher LOF doses generally increase plant biomass up to an optimal threshold, beyond which nutrient absorption efficiency by roots declines. Overall, the optimal LOF dosage for maximizing biomass growth in Mucuna bracteata DC ranges between 25–30 mL/polybag. The use of coffee husk waste as an organic nutrient source presents a sustainable alternative for improving plant productivity while reducing dependency on synthetic fertilizers.

Abstract

The expansion of oil palm plantations is considered a major factor in the decline of tropical forest areas, and negatively impacting biodiversity, especially tree vegetation. This study aimed to identify tree vegetation types and the structure and composition of trees in two oil palm companies, namely PTPN IV and PTPN III. Identification of forest areas was performed by collecting data from the plantations, and processed tree species data using the quadrat method and calculated using the Shannon-Wiener and Simpson's diversity indices. Results showed that tree species with the highest Importance Value Index is Koompasia excels with a percentage of 92.95%, Shorea sp (56.7%), and Koompasia malaccensis (69.32%). Based on tree height, stratum A (>30 m) dominated in PTPN IV with 840 individual/ha, while in PTPN III-1 stratum B (20-30 m) dominated with 330 individual/ha. There were 600 individual/ha in PTPN IV with diameter class of 10-29 cm, 250 individual/ha with diameter class of 30-49 cm in PTPN III-1, and 220 individual/ha with 30-49 cm diameter in PTPN III-2. The highest Shannon-Wiener diversity index (2.148) was found in PTPN III-2, and the highest Simpson's dominance index (0.187) was found in PTPN IV. An inverted "J"-shaped curve indicated that the forest area had a good stand structure, with more small-diameter trees than large-diameter ones. Keywords: High Conservation Value, Importance Value Index, Shannon-Wiener Index, Simpson's Index of Oil Palm.

Abstract

Oil palm (Elaeis guineensis Jacq) is a plant with a higher vegetable oil content than other oil-producing plants, so palm oil is widely used as the main raw material for processed vegetable oil. The increasingly limited land area and the larger land area in Indonesia so that the space for plantation companies to expand the land is increasingly limited, so that the expansion of oil palm plantations began to change from optimal land to suboptimal land. Soil physical properties are properties related to the shape or original condition of the soil. This study aims to determine the physical properties of soil (texture, porosity, moisture content, soil color, particle density, and bulk density) on peatlands in the tidal area of PT Sinar Gunung Sawit Raya. This research used survey method with descriptive analysis. The soil samples taken were peat soil in the tidal area with purposive random sampling method at a depth of 30 cm. This research was conducted in November 2023 and continued in the laboratory for testing each soil physical properties. The results of the research on soil physical properties at PT Sinar Gunung Sawit Raya on peatlands in tidal areas show that the soil texture is loamy sand, soil porosity is good, moisture content is relatively normal, soil color looks relatively dark, particle density is still low and bulk density value shows low. Keywords: Loamy sand, Oil palm, Peat soil, Soil color, Soil texture.

Abstract

Energy is essential for human life, yet dependence on fossil fuels and other non-renewable resources contributes to global energy crises and environmental degradation. Biogas is an environmentally friendly alternative that has the potential to partially replace fossil fuels. Palm Oil Mill Effluent (POME), which contains high concentrations of biodegradable organic matter, is a promising substrate for biogas production through anaerobic fermentation. This study aims to evaluate the potential of Palm Oil Mill Effluent (POME) as a substrate for biogas production using a Continuous Stirred Tank Reactor (CSTR) under mesophilic conditions (35–37oC). The experiment was conducted for 30 days with at a laboratory scale (10 L reactor volume). Feedstock characterization (COD, TSS, TS, VS, and pH) confirmed that POME has high organic content and slightly acidic conditions, supporting its suitability for anaerobic digestion. The results show that anaerobic fermentation of POME produced biogas with an average methane (CH4) concentration of 66–71%, indicating stable digestion performance and relatively high efficiency. These methane levels indicate stable digestion performance and relatively high process efficiency. Overall, the findings confirm that POME is a promising feedstock for biogas production and can contribute to renewable, environmentally friendly energy supply.
