Abstract

Penelitian Budidaya Tanaman Sawi (Brassica Juncea L.) Pada Media Tanam Yang Berbeda Secara Vertikultur. Tujuan penelitian untuk mengetahui teknik budidaya tanaman Sawi yang lebih efisien dengan menggunakan media tanam yang berbeda secara vertikultu. Penelitian dilakukan di kebun percobaan Fakultas Pertanian Universitas Medan Area yang berlokasi di jalan Kolam No. 1 Medan Estate, Kecamatan Percut Sei Tuan dengan ketinggian tempat  25 m dari permukaan laut, topografi datar dan jenis tanah alluvial.  Penelitian ini dilaksanakan Mei 2014 / Juli  2014, penelitian mengunakan rancangan acak kelompok faktorial yang terdiri dari 2 faktor perlakuan, yaitu Faktor pertama Pola Budidaya (P) yang terdiri dari 3 taraf, P1 = Konvensional P2 = Vertikultur bambu P3 = Vertikultur botol plastik bekas. Faktor kedua Media tanam (M) yang terdiri dari 2 taraf : M1  =  tanah  + pupuk kandang sapi dan  M2  =  tanah  + pupuk kompos sayuran. Hasil penelitian menunjukan bahwa pemberian pupuk kandang sapi dan kompos sayur tidak menunjukan perbedaan yang nyata terhadap pertumbuhan tanaman sawi, tetapi pola tanam menunjukan pengaruh yata pada pertumbuhan tanaman sawi hijau (P1) konvesional dan disusul dengan pelakuan perikultur yang tidak jauh berbeda yaitu P2 (verikultur dengan Bambu). Secara umum penelitian tidak menunjukan hasil yang berbeda nyata tetapi pengunaan pola tanam verikultur dengan bambu dapat digunakan karea hasil tidak jauh berbeda dengan konvensional.

Abstract

This study aims to examine the effect of NPK fertilizer application, bagasse compost, and its interaction on the growth and production of cucumber plants (Cucumis sativus L.) of the Zafaty F1 variety. The research was carried out using a factorial Group Random Design (RAK) with two factors, namely the dose of NPK fertilizer (1, 2, and 3 tons/ha) and bagasse compost (0, 10, 20, and 30 tons/ha). The observed parameters included plant height, stem diameter, flowering age, fruit diameter, number of fruits per sample and per plot, and fruit weight per sample and per plot. The results of the analysis showed that NPK fertilizer had a very real effect on the acceleration of flowering life, while bagasse compost had a real effect on the number of fruits per sample and per plot in the second harvest. However, no significant effect of either treatment was found on vegetative growth (stem height and diameter) as well as fruit size and weight. These findings indicate that NPK fertilization and bagasse compost have not been optimal in increasing overall cucumber production. Further research is needed to explore more precise dosage and sustainable application strategies to maximise crop yields.

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.

Abstract

This study aimed to determine the effect of goat manure and mycorrhiza on the growth and yield of melon plants (Cucumis melo L.). The research was conducted at the Experimental Field of the Faculty of Agriculture, Universitas Medan Area, from February to May 2025, using a completely randomized design (CRD) with a factorial arrangement of two factors: goat manure dosage (0, 10, and 20 tons/ha) and mycorrhiza concentration (0, 5, and 10 g/plant), with three replications. The observed parameters included plant height, leaf area, number of fruits, fruit weight per plant, and sweetness level. The results showed that the combination of goat manure and mycorrhiza significantly affected the growth and yield of melon plants. The treatment combination of 20 tons/ha goat manure and 10 g/plant mycorrhiza produced the highest plant height, fruit weight, and sugar content. The integration of these two organic inputs improved nutrient uptake efficiency, enhanced soil structure, and increased fruit quality. This approach has the potential to serve as an environmentally friendly cultivation strategy for sustainably increasing melon productivity.

Abstract

This study aims to determine the antibacterial ability of Cyperus rotundus extract in inhibiting the growth of Escherichia coli and Salmonella typhi by measuring the diameter of the inhibition zone. This research method used a completely randomized design (CRD) and LSD test as a follow-up test with one factor, namely variations in the concentration of C. rotundus extract 20%, 40%, 60%, 80% and 100%, distilled water as a negative control and the antibiotic chloramphenicol as a positive control. The results showed that the extract of C. rotundus could inhibit the growth of Escherichia coli with the largest inhibition zone diameter indicated by a concentration of 100% which was 2.33mm and the smallest inhibition zone diameter was found at a concentration of 20%, namely 1.00 mm. While in Salmonella typhi the largest inhibition zone was shown at a concentration of 100%, namely 3, 03mm and the smallest inhibition zone was indicated by a concentration of 20%, namely 1.07 mm. The results of the ANOVA and LSD tests with 95% confidence test showed that there was a difference in the average diameter of the inhibition zone in each treatment with variations in the concentration of C. rotundus extract with a concentration of 80% as the most effective.
