Wahyu Nahrul Firdaus — 2025-12-26

Pertanian perkotaan merupakan solusi strategis untuk memenuhi kebutuhan pangan masyarakat, khususnya dalam budidaya hortikultura. Salah satu komoditas sayuran yang permintaannya terus meningkat adalah kailan (Brassica oleracea L.). Namun, budidaya di perkotaan menghadapi tantangan dalam hal penyiraman yang sering kali kurang efisien jika dilakukan secara manual. Oleh karena itu, diperlukan sistem pengairan yang lebih efektif, seperti irigasi kapiler dan irigasi tetes. Keberhasilan budidaya juga sangat ditentukan oleh kecukupan air dan nutrisi yang tersedia. Pemanfaatan bahan organik seperti asam humat dapat membantu meningkatkan kualitas dan kuantitas hasil panen karena kemampuannya memperbaiki struktur media tanam, meningkatkan kemampuan menahan air, serta memfasilitasi penyerapan unsur hara oleh tanaman. Penelitian dilakukan di Kebun Percobaan Fakultas Pertanian Universitas IBA yang berada di Palembang, pada bulan April - Mei 2025, menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan dua faktor perlakuan. Faktor pertama adalah sistem pengairan (S0: penyiraman biasa, S1: irigasi kapiler, S2: irigasi tetes), dan faktor kedua adalah dosis asam humat (H0: 0 g.l^-1, H1: 1.5 g.l^-1, H2: 3 g.l^-1, H3: 4.5 g.l^-1). Hasil penelitian menunjukkan interaksi perlakuan berpengaruh signifikan terhadap bobot panen dan bobot kering tanaman. Perlakuan sistem pengairan berpengaruh signifikan terhadap tinggi tanaman, jumlah daun, luas daun, dan bobot panen, sedangkan perlakuan asam humat berpengaruh signifikan terhadap seluruh parameter pertumbuhan. Kesimpulannya, kombinasi irigasi kapiler dan asam humat 3 g.l^-1 memberikan hasil optimal untuk produksi kailan di lingkungan perkotaan.

Juliarni Juliarni — 2025-12-30

The cultivation of longan in Indonesia holds strong potential due to high consumer demand, favorable environmental conditions, and the availability of varieties well adapted to the local climate. However, pest attacks remain a major constraint, often reducing both the quantity and quality of fruit production. This study aimed to inventory the pest species associated with longan cultivation. The research was conducted through field surveys, with sampling locations determined using a purposive random sampling method. Insect specimens were collected directly by hand and preserved in vials containing 75% alcohol. The specimens were then examined under a microscope and documented. Observed parameters included the diversity index, evenness index, and dominance index, with data analyzed descriptively. The results showed that the primary pest attacks targeted the leaves and flowers of longan plants. A total of eight pest species belonging to two families—Scarabaeidae and Coreidae—were recorded. The pest diversity index (H’) was categorized as moderate (1.8), the evenness index (E) was high (0.9), and the dominance index (C) was low (0.2).

an Exploration of Plant Water Extracts in Environmentally Friendly Bioherbicide Innovation: A Literature Review

Edi Susilo — 2025-12-30

The use of synthetic herbicides in agriculture raises many problems, including weed resistance, ecological damage, and health risks. To address these issues, plant-based biological herbicides have been introduced as a safer and more sustainable alternative. This study focuses on plants that exhibit allelopathy, including those that contain phenolic compounds, flavonoids, terpenoids, alkaloids, and tannins, which have the potential to be compact and phytotoxic to weeds through various mechanisms, including inhibiting germination, root growth, cell respiration, and photosynthesis, and disrupting hormonal balance. Therefore, various water-extraction techniques, such as soaking, boiling, and maceration, were studied to obtain the maximum amount of bioactive compounds. Plants that produce potent phytotoxic compounds, including Sorghum bicolor, Ageratum conyzoides, Chromolaena odorata, Mikania micrantha, Azadirachta indica, and Tagetes erecta, have been tested to contain active compounds that are effective in suppressing the growth of various weeds. Adaptation and development of bioherbicides made from water-extract compounds in the field of research, although promising, also face various challenges, including degradation of the active compounds, variations in raw materials, low extract concentrations, and the need for standardization in extraction methods and formulations. Therefore, characterization techniques for potentially allelopathic materials, more sophisticated formulations such as microencapsulation and nanoformulation, and investigation of potentially synergistic compounds between plant extracts and beneficial microorganisms are needed. This study confirms that plant water extracts have great potential as environmentally friendly weed-control solutions that support sustainable agricultural systems.

PENGARUH PEMBERIAN PUPUK GUANO DAN POC AIR CUCIAN BERAS TERHADAP PERTUMBUHAN DAN HASIL TANAMAN MENTIMUN (Cucumis Sativus L)

Bimo Ahmad Supardi — 2025-12-30

Cucumber (Cucumis sativus L.) is a widely utilized plant in daily life, serving as a fresh vegetable, a base for pickles, juice, and even cosmetics. However, cucumber production in Indonesia has experienced a significant decline, partly due to the suboptimal availability of nutrients in the cultivation land. This study aims to explore the effects of guano organic fertilizer and rice wash water liquid organic fertilizer (POC) on the growth and yield of cucumber plants. The research was conducted in Bentiring Village, Bengkulu City, using a two-factor Randomized Block Design (RBD). The first factor was guano fertilizer with doses G0 (control), G1 (100 g/plant), G2 (200 g/plant), and G3 (300 g/plant), while the second factor was rice wash water POC with concentrations P0 (control), P1 (25 ml/L), P2 (50 ml/L), and P3 (75 ml/L). The analysis of variance revealed a significant interaction between guano fertilizer and rice wash water POC on various cucumber growth parameters, such as tendril length, number of leaves, number of fruits, fruit length, as well as fruit weight per plant and per plot. The best results were obtained from the combination of 300 g/plant of guano fertilizer and 75 ml/L of rice wash water POC, which produced a plot fruit weight of 2.01 kg. This study demonstrates that both types of fertilizers can improve the quality and quantity of cucumber yield, with rice wash water POC enhancing soil structure and increasing nutrient availability.

nurhajijah — 2025-12-30

This study aimed to evaluate the efficacy of neem leaf (Azadirachta indica) extract, soursop leaf (Annona muricata) extract, and their combination on the mortality and feeding activity of Sitophilus zeamais during maize grain storage. The experiment was conducted at the Plant Pest and Disease Laboratory, Faculty of Agriculture, UMSU, from October to November 2025 using a Completely Randomized Design (CRD) with four treatments: control, neem extract 10 mL L⁻¹, soursop extract 10 mL L⁻¹, and a mixed extract of neem and soursop (5 + 5 mL L⁻¹). Observed parameters included daily mortality for seven days and feed remnants after the observation period. Results showed variations in mortality among treatments; however, ANOVA indicated no significant differences (p > 0.05). The highest mortality occurred in the soursop treatment (53.3%), followed by neem (33.3%), control (30%), and the combined extract (13.3%). Feed consumption also did not differ significantly, with mean feed remnants ranging from 2.5 to 5.07 g. These findings suggest that the extract concentrations used were insufficient to produce significant insecticidal effects on S. zeamais. Further studies using higher concentrations, improved extraction techniques, or more stable formulations are recommended to enhance the potential of botanical extracts for protecting stored maize grains.

Onions are a type of horticultural commodity that is essential for seasoning food. The ever-increasing demand for red onion production has led a continuous increase in red onion production in the field to meet market needs. Shallot productivity can be increased through fertilization. The fertilization that can be done and is considered safe is organic fertilizer. Therefore, this study aims to determine the effect of mixed compost and biological POC on onion plants. This research was conducted in Sendang Rejo Village, Binjai, from November to February 2020, using a Randomized Block Design with 2 factors. The forst factor is a mixture of goat maure compost and rice straw (control, 1, 2, and 3 kg/plot), and the second factor is biological POC (control, 300, 400, 500 ml/liter water/plot). This research results show that the application of mixed compost and biological POC significantly affects plant height parameters at 3, 4, and 5 weeks after planting. The interaction between the two fators did not significantly affect all observed parameters.
