Abstract

Red chili pepper (Capsicum annuum L.) is a horticultural commodity with high economic value that is greatly influenced by agroclimatic conditions. In dry climate zone E (Oldeman classification), plant growth is often hampered due to water limitations and low soil fertility. This study aims to evaluate the effect of arbuscular mycorrhizal administration and liquid organic fertilizer (POC) of cow urine on the vegetative growth of red chili plants in dry climate zone E. The study was conducted using a factorial Random Group Design (RAK) with two factors: mycorrhizal dose (0, 35, 85, and 135 g/plant) and POC concentration of cow urine (0, 30, 35, and 40 ml/L), Each was repeated three times, making a total of 48 experimental units. The parameters observed included plant height, number of leaves, stem diameter, time of emergence and number of shoots. The results showed that the dose of mycorrhizal 135 g and the POC concentration of 40 ml/L gave the best results on almost all vegetative parameters. The interaction of the two also showed a significant influence on plant height and number of shoots. These findings support the application of bioagent-based eco-friendly technologies in sustainable farming systems on dry climates.

Abstract

Peanuts (Arachis hypogaea L.) are important food crops that require essential nutrients such as nitrogen (N) and potassium (K) for optimal growth. Efficient fertilization is the key to increasing yields, especially in marginal areas. This study aims to determine the effect of urea fertilizer and oil palm ash on the growth and yield of peanuts. The research was carried out at the Experimental Garden of the Faculty of Agriculture, University of Medan Area using a factorial Group Random Design (RAK) with two factors: the dose of urea (0, 200, 250, 300 kg/ha) and oil palm ash (0, 15, 20, 25 tons/ha), each repeated three times. The parameters observed included plant height, flowering start day, number and weight of pods. The results showed that the application of oil palm ash had a significant effect on plant height, number of pods, and pod weight per sample, with the best treatment at a dose of 25 tons/ha. In contrast, urea fertilizers did not show a significant influence on all parameters. These results indicate that oil palm ash can be an effective and environmentally friendly alternative to organic fertilizers to increase peanut productivity.This study aims to determine the growth response and yield of peanut plants given urea fertilizer and oil palm bunch ash. This study was conducted using a factorial experimental design consisting of two factors, namely urea fertilizer and oil palm bunch ash. The results showed that the administration of urea fertilizer and oil palm bunch ash can increase the growth and yield of peanut plants. The administration of 200 kg/ha of urea fertilizer and 10 tons/ha of oil palm bunch ash can increase the yield of peanut plants by 35.6% compared to the control. Therefore, the administration of urea fertilizer and oil palm bunch ash can be an alternative to increase the growth and yield of peanut plants.

Abstract

Penelitian ini bertujuan untuk menganalisis dan membandingkan kadar metabolit primer pada daun pisang Kepok Kuning (Musa × paradisiaca L., var. Kepok Kuning) yang diperoleh melalui kultur jaringan dan budidaya konvensional. Kultur jaringan merupakan teknik perbanyakan modern yang memungkinkan produksi bibit secara massal dan seragam secara genetik, namun kondisi lingkungan in vitro yang berbeda dengan in vivo dapat memengaruhi komposisi biokimia tanaman. Analisis dilakukan terhadap metabolit primer utama, meliputi karbohidrat, protein, dan lipid, yang berperan penting dalam pertumbuhan dan metabolisme seluler. Metode kromatografi cair kinerja tinggi (HPLC) digunakan untuk analisis karbohidrat, sedangkan kadar protein total diukur secara spektrofotometri. Hasil penelitian menunjukkan bahwa daun pisang hasil kultur jaringan memiliki kadar gula total (glukosa, fruktosa, sukrosa) yang lebih tinggi dibandingkan daun dari tanaman konvensional, sedangkan kadar protein dan lipid tidak berbeda signifikan. Perbedaan ini mencerminkan adanya adaptasi fisiologis akibat perbedaan lingkungan pertumbuhan. Studi ini menegaskan bahwa teknik kultur jaringan dapat memengaruhi profil metabolit primer tanaman dan menjadi dasar penting bagi optimalisasi produksi serta peningkatan kualitas bahan tanaman.

Abstract

Rice (Oryza sativa L.) is a major food commodity, but its production is often threatened by abiotic stresses, one of which is salinity (high salt content) in agricultural land, especially in tidal swamp land or due to seawater intrusion. Salinity can inhibit growth and reduce rice productivity through three main mechanisms: (1) osmotic stress that disrupts water and nutrient absorption, (2) toxicity of sodium (Na+) and chloride (Cl−) ions that disrupt metabolism, and (3) nutrient imbalance. The salinity tolerance limit for paddy rice that is compatible with high productivity is generally less than 3.74 dS/m. This study is entitled The Effect of Salinity Stress Levels on the Growth of Various Rice Varieties (Oryza sativa L). This study is a salinity treatment on various rice varieties at various levels. The purpose of this study is to determine the types of varieties that are tolerant to different levels of salinity. The study used a factorial randomized block design (RAK) with four varieties as treatment factors: Nutrizing variety (V1), Inpari variety (V2), Inpari33 variety (V3), and Mekonga variety (V4). The second factor was the level of salinity stress, consisting of: C1 = 0, C2 = 4, C3 = 8. The observation parameters measured were plant height (cm), number of tillers, number of leaves, and flowering age, with most results showing no significant differences.

Abstract

This study aimed to determine the effect of Plant Growth Promoting Rhizobacteria (PGPR) application on the growth and yield of intercropped sweet corn (Zea mays saccharatta Sturt L.) and chili pepper (Capsicum frutescens L.). The experiment was conducted from June to August 2022 in Percut Sei Tuan, Deli Serdang, North Sumatra, using a Split-Plot Design with two factors: cropping system (sweet corn monoculture, chili monoculture, and intercropping) and PGPR concentration (0%, 1%, 2%, and 3%). Observed parameters included vegetative growth and yield components. The results showed that the cropping system significantly affected plant height and leaf number of sweet corn, and the number of productive branches of chili. PGPR application had no significant effect on sweet corn growth and yield but significantly affected stem diameter and yield per plot of chili. The interaction between intercropping and PGPR significantly affected chili growth but not sweet corn. Therefore, PGPR application was more effective in enhancing chili growth and yield than sweet corn under intercropping systems.

Abstract

This study aims to determine the effectiveness of lemongrass (Cymbopogon nardus) extract, noni leaves (Morinda citrifolia), and papaya leaves (Carica papaya) in suppressing the population of maize weevil pests (Sitophilus zeamais) during maize seed storage. The research was conducted at the Organic Chemistry Laboratory of the University of North Sumatra using a Completely Randomized Design (CRD) with 10 treatments and 3 replications. The data were analyzed using ANOVA and further tested with the DMRT at 5%. The results showed that the treatments had a significant effect on the mortality of S. zeamais (p 0.05). The highest mortality (65%) was obtained from the treatment of 15 g noni leaves and 15 g lemongrass per 100 g of maize seeds, whereas the control was only 7.5%. This effectiveness is related to bioactive compounds such as saponins, flavonoids, and citronellal, which are toxic to insects. These results indicate the potential use of local plant extracts as environmentally friendly botanical pesticides for controlling storage pests and maintaining the quality of corn seeds.

Abstract

This study aims to compare the primary metabolite content of yellow Kepok banana (Musa paradisiaca L.) leaves obtained through tissue culture and conventional cultivation methods. Yellow Kepok banana is one of Indonesia’s superior varieties with high economic value and great potential as a raw material for the food industry and as a source of value-added biomass. In the context of agricultural biotechnology, tissue culture techniques not only enable rapid and uniform plant propagation but may also influence the biochemical composition of plants through more controlled growth conditions. This study employed a descriptive experimental design with two treatments and three replications. Primary metabolites analyzed included carbohydrates, proteins, fats, crude fiber, ash, and moisture content, using the proximate (AOAC) method. The results showed that leaves derived from tissue culture had higher levels of carbohydrates (44.15% DM), proteins (19.77% DM), and fats (7.82% DM) compared to conventionally grown plants (39.93% DM; 16.13% DM; 6.20% DM). Conversely, conventionally grown leaves contained higher crude fiber, ash, and moisture. Controlled tissue culture conditions enhanced physiological efficiency and energy metabolite accumulation, whereas natural environments favored structural component formation. These findings highlight the potential of tissue culture as an effective method for producing banana leaf biomass with improved nutritional and metabolite profiles.

Abstract

Limbah cangkang kerang dara (Anadara granosa) merupakan produk sampingan dari industri perikanan yang sangat melimpah di Indonesia, namun pemanfaatannya masih terbatas dan cenderung menimbulkan permasalahan lingkungan. Cangkang kerang mengandung kalsium karbonat (CaCO₃) serta mineral lain yang berpotensi digunakan sebagai bahan amelioran untuk memperbaiki kualitas tanah marginal. Penelitian ini menggunakan metode studi literatur dengan pendekatan narrative review untuk mengkaji potensi cangkang kerang dara sebagai bahan amelioran melalui analisis kualitatif terhadap berbagai hasil penelitian terdahulu. Hasil kajian menunjukkan bahwa aplikasi cangkang kerang mampu menetralkan keasaman tanah, meningkatkan ketersediaan unsur hara makro dan mikro, memperbaiki sifat fisik tanah, serta mendukung aktivitas mikroorganisme tanah (Jubaedah et al., 2023). Namun demikian, efektivitas penggunaannya dipengaruhi oleh ukuran partikel, dosis aplikasi, serta kondisi spesifik tanah marginal. Secara keseluruhan, pemanfaatan cangkang kerang dara memiliki prospek besar sebagai alternatif amelioran ramah lingkungan, meskipun masih diperlukan penelitian lanjutan untuk standarisasi dan penerapan dalam skala lapangan.

Abstract

This study was conducted to evaluate the effect of liquid organic fertilizer (LOF) from lamtoro leaves and rice husk biochar on the growth of kale (Brassica oleraceae). The research was motivated by the low productivity of kale in Indonesia due to the lack of sustainable cultivation practices, thus requiring environmentally friendly fertilization alternatives. The experiment was carried out at the experimental field of the Faculty of Agriculture, Universitas Medan Area, from August to September 2024, using a factorial randomized block design (RBD). The rice husk biochar factor consisted of 4 levels: P0 (without biochar), P1 (1.44 kg/plot), P2 (2.88 kg/plot), and P3 (4.32 kg/plot). The lamtoro leaf LOF factor also consisted of 4 levels: N0 (without LOF), N1 (100 ml/900 ml water), N2 (200 ml/800 ml water), and N3 (300 ml/700 ml water). Thus, 16 treatment combinations were obtained. Observed parameters included plant height, number of leaves, fresh weight per sample, fresh weight per plot, economic yield, and root weight. The results showed that rice husk biochar significantly affected plant height, number of leaves, fresh weight per sample, fresh weight per plot, and economic yield per sample plant, with the best treatment at a dose of 4.32 kg/plot (P3). Meanwhile, lamtoro leaf LOF significantly affected economic yield per plot, with the best treatment being N3 (300 ml/700 ml water). The combination of both treatments had no significant effect on all observed parameters.
