Abstract

Mung bean plants include legume plants whose roots have root nodules which are a symbiosis between the roots and Rhizobium japonicum bacteria. Root nodules function to fix free nitrogen elements, besides that they can also fertilize the soil because they can save the use of NH3 available in the soil and provide nitrogen elements to the soil.Rhizobium is a genus of soil bacteria that are able to symbiotize with plants. There are many types of Rhizobium bacteria, especially in soils with high organic matter content. This study was conducted to determine the compatibility of Rhizobium japonic in mung bean plants (Vigna radiata L) with Rhizobium sp grown on Mucuna bracteata land. To determine the effect of some phosphate fertilizers on the modulation of mung bean (Vigna radiata L.) The results showed that the application of Rhizobium japonicum on mung bean (Vigna radiata L) with Mucuna bracteata land did not show a significantly different adjustment (compatibility) to the height and number of plant leaves. The P0 treatment showed significant differences in the root nodule parameters of the P1, P2 and P3 treatments. Phosphate fertilizer with 50% RP TSP content is the best composition.

Abstract

Palm oil mill boiler ash is a solid industrial waste available in large quantities, but its utilization is still limited. This waste has alkaline properties and nutrient content that has the potential to improve the physical-chemical properties of tropical acid soils, such as pH, cation exchange capacity, and macronutrient availability, making it a potential sustainable soil ameliorant. This study aims to process organic fertilizer, namely an organomineral product based on boiler ash, with the aim of evaluating its chemical characteristics and assessing its potential application as a soil ameliorant. The analysis results show that Puler has a pH value of 9 and a nutrient composition that can improve soil quality without heavy metal concentrations above the Indonesian national standard threshold. These findings indicate that Puler can be an efficient alternative ameliorant and supports the utilization of palm oil industry waste. In addition, this puler also meets the criteria for organic fertilizer standards according to SNI 7763:2024

Abstract

Serangan hama serangga merupakan salah satu faktor pembatas utama dalam kegiatan budidaya tanaman pertanian karena dapat menurunkan produktivitas dan kualitas hasil panen. Pengendalian hama yang masih didominasi penggunaan pestisida kimia berpotensi menimbulkan dampak negatif terhadap lingkungan, kesehatan manusia, serta memicu resistensi hama. Oleh karena itu dilakukan program pengabdian kepada masyarakat berupa pengendalian hama melalui pemasangan perangkap feromon (ferotrap) di Desa Baja Dolok, Kecamatan Sipispis, Kabupaten Serdang Bedagai. Kegiatan ini bertujuan menawarkan alternatif pengendalian hama yang efektif, ramah lingkungan, dan efisien biaya. Metode pelaksanaan meliputi pemasangan ferotrap di lahan pertanian, pengamatan jumlah hama tertangkap, serta evaluasi tingkat serangan hama pada tanaman. Hasil menunjukkan penggunaan ferotrap mampu menekan populasi hama secara signifikan dan menurunkan tingkat kerusakan tanaman. Dengan demikian ferotrap berpotensi menjadi komponen penting dalam sistem Pengendalian Hama Terpadu (PHT) berkelanjutan.

Abstract

This study aims to analyse the density of microalgae mixculture cultivated in POME media with varying concentrations and to evaluate the effect of POME concentration on microalgae growth. Microalgae mixculture was cultivated in POME media with three concentration variations, namely 10%, 20%, and 30%. Cultivation was carried out for 15 days with cell density observations every three days using a haemocytometer. The results showed that microalgae density increased over time in all treatments. A POME concentration of 30% produced the highest microalgae density at each observation time, with a maximum density of 12,564 cells/ml on the 15th day, followed by concentrations of 20% and 10% at 11,980 cells/ml and 10,080 cells/ml, respectively. These results indicate that an increase in POME concentration has a positive effect on the growth of microalgae mixculture within the concentration range used. Microalgae density increased with cultivation time in all treatments. A 30% POME concentration resulted in the highest microalgae density, indicating that the higher nutrient availability in POME supports microalgae growth. Thus, POME has the potential to be utilised as an alternative medium for microalgae cultivation as well as an effort to manage palm oil industry wastewater.

Abstract

Weeds in oil palm plantations negatively affect the quantity and quality of fresh fruit bunches, inhibit plant growth, increase susceptibility to pests and diseases, interfere with water use, and raise production costs. This study aimed to identify dominant broadleaf weed species, evaluate herbicide resistance, determine weed regrowth time, and develop effective control strategies. A factorial randomized block design with 6 treatments and 2 controls was applied, with observations conducted every 7 days for 6 weeks. Results showed that the most dominant broadleaf weed was Synedrella nodiflora with a dominance level of 27.64%, while the lowest population was Asystasia intrusa at 12.36%. Herbicide application significantly increased weed mortality compared to the control, with paraquat treatment (P3) producing the fastest response, reaching early visible damage within hours and higher mortality rates (>50% by day 5). Resistance analysis indicated that weeds were still susceptible, with Resistance Index (RI) values of 1.53 (glyphosate) and 0.80 (paraquat). Weed regrowth began at 16 days after application (H+16), dominated by Ageratum conyzoides, Physalis minima, and Synedrella nodiflora. An effective weed control strategy involves maintaining proper application intervals and using low herbicide doses to delay resistance development.

Abstract

Gulma merupakan salah satu faktor yang dapat mengganggu pertumbuhan dan produktivitas tanaman kelapa sawit karena berkompetisi dalam memperoleh air, unsur hara, cahaya, dan ruang tumbuh. Komposisi dan dominansi gulma dapat berbeda berdasarkan kondisi lingkungan dan umur tanaman, sehingga identifikasi jenis gulma dominan diperlukan sebagai dasar pengelolaan gulma yang tepat. Penelitian ini bertujuan untuk mengidentifikasi jenis gulma dan mengetahui tingkat dominansi gulma pada perkebunan kelapa sawit rakyat di Kecamatan Panai Hulu, Kabupaten Labuhanbatu. Penelitian dilaksanakan dengan metode observasi lapangan menggunakan purposive sampling. Pengamatan dilakukan pada areal kelapa sawit tahun tanam 2002 dan 2021 menggunakan petak kuadrat berukuran 1 × 1 m. Data yang dikumpulkan meliputi jenis dan jumlah individu gulma pada setiap petak pengamatan. Analisis vegetasi dilakukan dengan menghitung kerapatan, kerapatan relatif, frekuensi, frekuensi relatif, dan Indeks Nilai Penting (INP). Hasil penelitian menunjukkan terdapat 14 jenis gulma dengan total 1.109 individu yang tersebar pada 104 petak pengamatan. Pada tanaman tahun tanam 2002, Ageratum conyzoides merupakan gulma paling dominan dengan INP sebesar 33%, sedangkan pada tahun tanam 2021 Nephrolepis biserrata merupakan gulma paling dominan dengan INP sebesar 26%. Syzygium polyanthum memiliki INP terendah sebesar 2% pada kedua tahun tanam. Hasil penelitian menunjukkan bahwa pengendalian gulma perlu mempertimbangkan jenis dan tingkat dominansi gulma pada masing-masing kondisi tanaman.

Abstract

Soil fertility is one of the main factors affecting oil palm productivity, particularly in highland areas with varying topographic conditions. Differences in land slope are believed to influence the distribution of soil nutrients due to erosion and nutrient leaching. This study aims to analyze the content of nitrogen (N), phosphorus (P), potassium (K), organic carbon, and topsoil pH on flat and sloping land at the Bah Birong Ulu Plantation, PTPN IV Regional II. The study employs a quantitative approach using field survey methods and descriptive analysis. Soil samples were collected from flat and sloping land using a soil auger at several observation points. Laboratory analysis was conducted to determine nitrogen content using the Kjeldahl method, phosphorus using the antimony molybdate colorimetric method, potassium using flame photometry, organic carbon using the Walkley and Black method, and pH measurement using a pH meter. The research data were analyzed using a two-sample t-test under the assumption of unequal variances. The results of the study indicate that there are no statistically significant differences in the nitrogen, phosphorus, potassium, organic carbon, and soil pH levels between flat and sloped land. The average nitrogen content in sloped soil was 0.53% and in flat soil was 0.50%, organic carbon content was 1.37% and 1.17%, respectively; phosphorus content was 33.45 ppm and 37.65 ppm; potassium content was 0.637 me/100 g and 0.611 me/100 g; and soil pH was 5.34 and 5.80. These results indicate that topographic conditions have not yet had a significant effect on the distribution of soil nutrients at the study site.\n\nThis study concludes that plantation management practices such as fertilization, soil conservation, and organic matter management have a greater influence than land slope conditions in maintaining soil nutrient stability. It is hoped that these findings will serve as a basis for developing more effective soil fertility management strategies and fertilization recommendations for oil palm plantations in highland areas.
