Abstract

The research was conducted at the Development University of Pancabudi, the agricultural lab of Glugur Rimbun starting from January until April 2020. This research was conducted using an experimental method using a Randomized Block Design (RAK) with 4 treatments and 6 groups/replication. The observed plant response was in the form of a plant height variable (cm), several leaves (strands), wet weight of plants (g), dry weight of plants (g), root length (cm), and organoleptic test. Based on the research results obtained, then it can be concluded that hydroponic nutrition with a concentration of 450 ppm (P1) has a good effect on the growth of red lettuce plants, namely producing high18.64 cm at the 4th week and the number of leaves 21.80 at the 4th week, weight 114.22 g in wet, 5.94 in dry, and 29.18 cm in root length.

Abstract

Pemberian pupuk anorganik yang berlebihan di tingkat petani menyebabkan produktivitas lahan menurun. Oleh karena itu, penambahan organik yang berfungsi sebagai bahan penyeimbang yang dapat menyerap sebagian zat sehingga senyawa yang berlebihan tidak merusak tanaman. Salah satu upaya untuk meningkatkan produksi bawang merah melalui teknik budidaya adalah dengan aplikasi bahan organik dan pemberian ekoenzim. Penelitian ini menggunakan Rancangan Acak Kelompok Faktorial yang terdiri dari 2 faktor perlakuan yaitu faktor I adalah Media Tanam (M) yang terdiri dari topsoil 100%, topsoil (75%) + kompos kotoran ayam (25%), M2 : topsoil (50%) + kompos kotoran ayam (50%0 dan M3 : topsoil (25%) + kompos kotoran ayam (75%). Faktor II adalah Ekoenzim (E) yang terdiri dari 0 ml, 10 ml, 20 ml dan 30 ml. Prosedur penelitian terdiri dari pembuatan kompos kotoran ayam, analisa tanah awal, analisa pupuk organik kotoran ayam, persiapan ekoenzim, persiapan lahan, persiapan umbi, aplikasi media tanam, penanaman, aplikasi ekoenzim, penentuan tanaman sampel pemeliharaan dan panen. Pengamatan tanaman meliputi tinggi tanaman (cm) dan jumlah daun (helai). Metode analisis data yaitu rancangan acak kelompok (RAK) Faktorial dan uji lanjutan bagi perlakuan yang nyata dengan menggunakan uji beda rata Duncan. Hasil penelitian didapat yaitu pemberian media tanam berupa topsoil 75% + kompos 25% mampu merespon pertumbuhan tanaman bawang merah. Kata Kunci : Bawang Merah, Ekoenzim, Media Tanam, Pertumbuhan

Abstract

This research was conducted on Jalan Tampok, Tanjung Selamat Village, Sunggal District, Deli Serdang Regency, North Sumatra. A non-factorial Randomized Block Design  was used, consisting of only one factor, with five treatments and four replications: 0, 1, 2, 3, and 4 liters of coconut water fertilizer. The results showed that the use of coconut water fertilizer had no significant effect on plant height 1, 2, and 3 weeks after planting, and fruit weight per plot. However, it had a highly significant effect on plant height 4 and 5 weeks after planting, stem diameter, number of leaves, and root length.   In general, increasing the dosage of coconut water POC tends to result in a better growth response during the vegetative phase of the plant. This suggests that the natural hormones in coconut water can support plant cell division and elongation. However, plant response to treatment is still influenced by environmental factors and dosage, so not all parameters show a significant effect. Further research is needed to determine the optimal dosage that is more effective on production yields.

Abstract

Improper storage of grain and rice often trigger post-harvest pest infestations that reduce food quantity and quality. Many traditional farmers are not yet aware of this threat. This study aims to identify post-harvest insect pest species, estimate their populations, and determine effective traps in traditional rice and paddy warehouses. The research results are expected to serve as a basis for farmers in selecting appropriate control measures. The study was conducted from February to May 2026 in traditional storage facilities in Tandam Hilir Dua Village, Hamparan Perak District, Deli Serdang Regency, North Sumatra. Insect identification was performed at the Entomology Laboratory of the North Sumatra Animal, Fish, and Plant Quarantine Center (BBKHIT North Sumatra). Research methods included rice sampling, grain sampling, setting ultraviolet light traps and yellow sticky traps inside the storage facility. Eleven insect pests were found: Sitotroga cerealella, Rhyzopertha dominica, Cryptolestes ferrugineus, Cryptolestes pusillus, Sitophilus oryzae, Tribolium castaneum, Palorus ratzeburgii, Oryzaephilus surinamensis, Coelopalorus foveicollis, Alphitobius diaperinus dan Tenebroides mauritanicus. The population of Sitotroga cerealella (12,991 individuals) was higher than that of other stored product pest insects found in the storage, whereas the lowest populations were recorded for Alphitobius diaperinus and Tenebroides mauritanicus (1 individual each). Yellow sticky traps captured more stored product pest insects than ultraviolet light traps, rice sampling method, and grain sampling method.

Abstract

This study aimed to analyze the effect of the interaction between soybean varieties and the dosage of goat urine liquid organic fertilizer (POC) on the growth and yield of several soybean varieties (Glycine max (L.) Merrill). The research was conducted at the experimental field of Universitas Pembangunan Panca Budi Medan, Sampe Cita Village, Kutalimbaru Subdistrict, Deli Serdang Regency, North Sumatra Province. The method used was a Factorial Randomized Complete Block Design (RCBD), consisting of two factors with three replications. The first factor was soybean variety, namely Dering 1, Devon 1, and Dega 1, while the second factor was the dosage of goat urine POC, namely 0 ml, 400 ml, and 800 ml. The observed data were further tested using Duncan's Multiple Range Test (DMRT) at the 5% level. The results showed that the combination of Devon 1 variety with a POC dosage of 400 ml (K1) produced more consistent and uniform growth compared to Dering 1 and Dega 1 varieties. This superiority was evident in parameters such as plant height, number of productive branches, flowering age, number of pods per sample, dry seed weight per sample, dry seed weight per plot, and root length. The selection of Devon 1 variety combined with a 400 ml POC dosage can be recommended as an effective cultivation strategy to optimize soybean growth and yield while improving soil fertility.

Abstract

Rice (Oryza sativa L.) is a major staple crop in Indonesia, but its production has declined, requiring efforts to improve plant growth. This study aimed to determine the effect of humic acid application and varietal differences on the vegetative growth of rice. The experiment was arranged in a factorial Randomized Complete Block Design with two factors: humic acid doses (0, 30, and 60 g/plot) and rice varieties (Inpari 32, Inpari 16 Pasundan, and IR64), with three replications. Observed parameters included plant height, number of tillers, fresh and dry weight of shoots, and roots. Data were analyzed using analysis of variance followed by Duncan’s Multiple Range Test at a 5% significance level. The results showed that humic acid sign ificantly affected all growth parameters, with the best result at 60 g/plot. Varietal differences affected only some parameters, while the interaction was not significant. Humic acid improved plant growth by enhancing soil properties and nutrient availability.
