Gliricidia leaves are rich in nitrogen, phosphorus, and potassium, which are essential nutrients for plant growth. This makes Gliricidia leaves a potential raw material for liquid organic fertilizer (LOF). Therefore, this study was conducted to determine the optimal dosage of Gliricidia leaf LOF that can be applied to enhance the growth of Green Mustard (Brassica junceaL.). The study used a Completely Randomized Design (CRD) with five treatments. The treatments consisted of a control (P0), 30 ml LOF/liter (P1), 60 ml LOF/liter (P2), 90 ml LOF/liter (P3), and 130 ml LOF/liter (P4). The observed parameters included plant height (cm), number of leaves (leaves), and leaf width (cm) at 7, 14, 21, and 28 days after planting (DAP). The data were analyzed using ANOVA followed by the Least Significant Difference (LSD) test at the 5% level, using SPSS 20 software. The results showed significant effects on plant height, number of leaves, and leaf width between the control and each dosage of Gliricidia leaf LOF. The dosage of 130 ml LOF/liter resulted in the highest average growth in plant height, number of leaves, and leaf width compared to the control and the 30, 60, and 90 ml LOF/liter treatments. Therefore, it is concluded that applying 130 ml of Gliricidia leaf LOF per liter of water is recommended to enhance the growth of Green Mustard.

Increasing palm oil factory production has an impact on increasing the palm oil waste produced. Palm oil mill waste can be classified into three types, namely solid waste, liquid waste and waste. Processing or utilization of empty palm oil bunches (EPOB) by palm oil mills (POM) is still very limited. The chemical content of naturally derived plant materials such as lignin, cellulose, hemicellulose and other materials, these contents are potential materials for strengthening household products such as carpets. The characteristics of EPOB fiber is that it has short fibers between 3-8 cm. The binder used is composite latex made from concentrated latex. The aim of this research on the characteristics of palm oil empty fruit bunch (EPOB) fiber composites with composite latex adhesive in making carpets is to obtain an increase in tensile strength as a characteristic of EFB fibers with composite latex, to obtain an optimal composition between fiber volume and latex compound to improve the mechanical properties of the carpet; and Creating new materials from natural sources that are easily degradable and environmentally friendly. The research results showed that the optimal composition produced in worm carpet was Treatment A4 with a formulation of 250 g of EFB fiber with a breaking stress value of 1.1 N/mm2, elongation at break of 240%, and tear resistance of 6.1 kg/cm3.

Efektivitas Kombinasi Ekstrak Limbah Kulit Bawang Merah dan Kulit Bawang Putih serta Serai sebagai Pestisida Organik terhadap Serangan Ulat Jerman (Tenebrio molitor) pada Tanaman Selada (Lactuca sativa)

Rizal Faturahman — 2025-06-27

Agriculture plays a crucial role in sustaining food security and the economy in Indonesia. Lettuce (Lactuca sativa), especially green curly lettuce, is a promising horticultural crop due to its relatively short growth period and high nutritional value. This study aimed to evaluate the effectiveness of organic pesticides derived from shallot peel, garlic peel, and lemongrass in controlling pest damage on lettuce. In this study, we conducted an experiment using Tenebrio molitor (mealworms) as a simulated pest attack on lettuce plants. The experiment used a Completely Randomized Design (CRD) with four treatments: P0 (no pesticide), P1 (shallot peel), P2 (shallot + garlic peel), and P3 (shallot + garlic peel + lemongrass), each replicated five times. Damage levels were measured organoleptically and analyzed using ANOVA and LSD tests at a 5% significance level. The P3 treatment resulted in the lowest leaf damage (1.63%), while the P0 treatment showed the highest (90%). The effectiveness of the organic pesticide is attributed to active compounds such as phenolics and flavonoids in shallot peel, allicin in garlic, and citronellal in lemongrass, which possess insecticidal properties. These findings demonstrate that combining these organic materials can synergistically suppress pest activity. In conclusion, organic pesticides formulated from agricultural waste materials offer a sustainable and eco-friendly alternative to chemical pesticides in lettuce cultivation.

Reni Rahmawati — 2025-06-27

The cultivation of Swamp Island in peatlands has been widely carried out by communities in Central Kalimantan Province, but it often fails due to various factors, such as land fires and unfavourable environmental conditions. One way to increase the growth of swamp pulai saplings is the use of Fumyco biofertilizer. This study aims to analyse the growth of swamp island saplings. This research was carried out for 3 months from October to December 2024. The research location is in the Green House, Department of Forestry, Faculty of Agriculture, University of Palangka Raya. The research materials and methods used are in the form of measuring bars, polybags, sprinklers, digital cameras and tally sheets. The materials used are peat soil, swamp saplings and Fumyco biofertilizer. Data analysis includes percentage of survival, plant height (cm) and number of leaves. This study used RAL with 5 (five) Fumyco treatments: Control (P₀), (P1) 2 grams, (P2) 4 grams, (P3) 6 grams, (P4) 8 grams and (P5) 10 grams. The results showed that the percentage of swamp island saplings in the 10 gram Fumyco treatment had a value of 88.89%, followed by the 2 gram Fumyco treatment of 77.78%, the treatment of 4 grams, 6 grams and 8 grams of 66.67%, while the control treatment was 66.67%. The results of the analysis of Fumyco biofertilizer application on the height and number of leaves of swamp island plants showed no significant difference. This is suspected because the observation time is only 3 months, but visually in the field the treatment has better growth compared to Control.

As fossil fuels continue to deplete, alternative energy sources need to be explored. Wood pellets process sawdust into fuel. This study examines wood pellets made from Gelam tree parts with different adhesive percentages. The research uses a completely randomized factorial design, with factors including tree parts (trunk, branches, twigs) and tapioca adhesive percentages (7.5%, 10%, 12.5%), followed by a Least Significant Difference (LSD) test. The results show that the tree part has no significant effect on moisture content, compressive strength, ash content, volatile matter, fixed carbon, or calorific value. However, the tree part significantly affects the density. The adhesive percentage has no significant effect on density and calorific value but significantly affects moisture content, compressive strength, ash content, volatile matter, and fixed carbon. The interaction between treatments has no significant effect on any pellet test parameters. The wood pellets show average values for the treatment interaction that meet the SNI 8021-2014 standards, except for moisture content.

Analisis Spasial Tingkat Kerawanan Kebakaran Hutan dan Lahan di Kabupaten Indragiri Hulu

Deden Afrizal — 2025-06-27

Forest and land fires in Indragiri Hulu district have increased significantly in the last five years. Overall in the last five years the total area of land and forest that has been burned due to forest and land fires that were burned intentionally or not exceeds 1600 hectares. As one of the districts that has a high plantation area and production of garden crops, making forest and land fires is one of the challenges faced. Therefore, it is necessary to assess the level of risk of forest and land fire vulnerability. As one of the techniques that can analyze the level of risk of such vulnerability spatially, the use of geographic information systems (GIS) is very supportive for the analysis of this level of vulnerability spatially. As a determinant of the level of vulnerability, several parameters are used, namely soil type, land cover, rainfall, population and infrastructure. The results of this level of risk and vulnerability show that several sub-districts in Indragiri Hulu district have a very high level of forest and land fire vulnerability. These districts include Rengat, West Rengat, Kuala Cenaku, Batang Gangsal, Seberida, Batang Cenaku, Rakit Kulim and Peranap.

Nyahu Rumbang — 2025-06-27

The purpose of this study was to study the effect of dolomite and compound biofertilizer on changes in the chemical properties of peat and edamame plant yields on inland peat. Using a Factorial Completely Randomized Design with 2 factors. The first factor is dolomite lime with 4 levels, namely D₀ = 0 t ha^-1, D₁ = 5 t ha^-1, D₂ = 10 t ha^-1, D₃ = 15 t ha^-1 and the second factor is compound biofertilizer with 4 levels, namely H₀ = 0 g.kg^-1 seed, H₁ = 5 g.kg^-1 seed, H₂= 10 g.kg^-1 seed, H₃ = 15 g.kg^-1 seed. The results of the study showed that increasing the dose of dolomite to 15 t ha^-1 together with the provision of biofertilizer at a dose of 10 or 15 g.kg^-1 of seed was able to provide the highest pH value, namely 4.06 - 4.18. In the parameter of peat total N value, only dolomite treatment gave a significant difference. The highest average Ca-dd value was obtained by addition 15 t ha^-1 of dolomite together with biofertilizer at a dose of 15 g.kg^-1 of seed, which was 14.897 (gmol(+)/kg). The highest Mg-dd value was obtained by addition 15 t ha^-1 of dolomite together with biofertilizer at a dose of 15 g.kg^-1 of seed, which was 36.680 (gmol(+)/kg). The highest number of pods (25.00 pods) and the highest pod weight (11.12 g) were obtained by addition 10 t ha^-1 of dolomite. The highest number of pods occurred by biofertilizer at 15 g.kg^-1 of seed (21.70 pods).

Analisis Implementasi Pola Kemitraan Kehutanan dalam Skema Perhutanan Sosial (PS) di Kalimantan Tengah: Studi Kasus Lanskap Rungan

Mariaty Mariaty — 2025-06-27

Forest partnership is one of the five schemes within the Social Forestry policy framework, aiming to improve the welfare of communities living in and around forest areas. Despite having a legal foundation through Ministerial Regulation of Environment and Forestry No. 09 of 2021 and Government Regulation No. 23 of 2021, its implementation in Central Kalimantan remains limited. This study analyzes the potential, challenges, and opportunities of forest partnership using a case study approach in the Rungan Landscape, which spans approximately 517,313 hectares and includes various forestry permits. The analysis reveals that although there is a potential for up to ±60,000 hectares of partnership area using a plantation plasma model, not a single Forest Partnership Agreement (NKK) has been realized. The main obstacles include differences in perception, bureaucratic procedures, and limited facilitation. The study recommends the development of regional policies, increased outreach efforts, and the involvement of universities as facilitators in the formulation and implementation of partnerships.
