Abstract

The Al Barkah Cooperative continues to produce goat milk, but the milk's distinctive aroma, unpopular with many, remains a limiting factor, resulting in low demand. To address this, innovation in goat milk processing is needed to ensure wider consumer acceptance. To enrich the cooperative's economic value, training and mentoring in dairy product processing are needed to optimize dairy farmers' milk production, including milk crackers and ginger milk. The training included lectures, demonstrations, and hands-on practice, covering everything from preparation to packaging. Evaluation results showed that 85% of participants felt they had gained new insights and were motivated to develop dairy products independently or in groups. Therefore, this activity has the potential to encourage business diversification, increase the added value of goat milk, and open wider market opportunities for the cooperative and the surrounding community.

Abstract

Hydroponics, a farming technique using nutrient-enriched water, has been widely practiced due to its suitability for limited agricultural land. One of the key factors affecting hydroponic efficiency is the nutrient blend, with AB Mix and liquid organic fertilizer playing a crucial role. This study aims to evaluate the potential of nanotechnology-based nutrient solution in hydroponic to enhance nutrient absorption and improve plant growth in different vegetable species. Five vegetable species, which include red lettuce, red spinach, green spinach, pakcoy, and kailan, were selected to assess the interaction between nutrient composition and vegetable species. A study with factorial design was conducted using a randomized complete block design (RCBD). The primary factor was the fertilizer composition and the secondary factor was the type of vegetable. The treatments consisted of Control (Well water + AB Mix), P1 (Nanotechnology water + 100% AB Mix), P2 (Nanotechnology water + 25% nanotechnology liquid organic fertilizer + 75% AB Mix), P3 (Nanotechnology water + 50% nanotechnology liquid organic fertilizer + 50% AB Mix), P4 (Nanotechnology water + 75% nanotechnology liquid organic fertilizer + 25% AB Mix), and P5 (Nanotechnology water + 100% nanotechnology liquid organic fertilizer). Growth parameters measured included plant height, fresh weight, dry weight, number of leaves, and leaf area. Data were evaluated using a two-way ANOVA to assess the effects of fertilizer composition and vegetable type, followed by a 5% DMRT test for mean comparison. The findings indicated that the use of liquid organic fertilizer technology influenced plant growth. The most optimal average growth was recorded in the P2 treatment (a combination of nanotechnology water, 25% nanotechnology liquid organic fertilizer, and 75% AB Mix), while the least favorable result was observed in P5 (nanotechnology water combined with 100% nanotechnology liquid organic fertilizer).

Abstract

Siput apel emas (Pomacea canaliculata L.) merusak tanaman padi dataran rendah pada fase pertumbuhan awal, menyebabkan kerusakan lebih dari 70% yang mengancam hasil panen dan pendapatan petani di seluruh Asia Tenggara. Ketergantungan pada pestisida sintetis berisiko menimbulkan kerusakan lingkungan dan efek pada organisme non-target, sehingga diperlukan alternatif nabati dari tanaman lokal. Penelitian ini mengevaluasi kemanjuran pestisida nabati terhadap mortalitas siput dan kerusakan pada padi Sambutan, dengan menggunakan rancangan acak lengkap (7 perlakuan, 3 ulangan): kontrol (P0); ekstrak batang brotowali (P1), daun sembung (P2), daun ketepeng cina (P3) pada konsentrasi 75 g L⁻¹; serta kombinasi (P4–P6) masing-masing pada konsentrasi 37,5 g L⁻¹. Parameter (kematian, persentase rumpun yang diserang, intensitas serangan) dianalisis melalui ANOVA dan uji Duncan (p < 0,05). Semua bahan botani secara signifikan meningkatkan efektivitas kontrol (p < 0,05). P1–P4 mencapai mortalitas 100%, namun P2 unggul dengan persentase rumpun yang terserang terendah (51,85%) dan intensitas serangan terendah (7,78%), melampaui yang lain. Ekstrak daun sembung (75 g L⁻¹) karenanya muncul sebagai pilihan yang unggul dan ramah lingkungan untuk pengendalian siput apel emas di sawah, mendukung pengendalian hama yang berkelanjutan di daerah rawan banjir.

Abstract

Durian (Durio zibethinus Murr.) is a tropical fruit commodity with high economic value and increasing market demand. However, increasing durian production in Indonesia still faces obstacles, particularly the limited availability of high-quality seedlings. Data from the Sijunjung Regency Central Statistics Agency (2024) shows that durian production fluctuates, namely 31,043 tons in 2022, increasing to 36,107 tons in 2023, then decreasing to 34,177.40 tons in 2024. This condition indicates the need for improvements in cultivation technology, especially in the seedling supply stage. Vegetative propagation through grafting techniques using the cleft grafting method is an effective alternative because it can produce uniform seedlings and accelerate the fruiting period. The success of grafting can be improved through the use of natural organic growth regulators (ZPT), such as coconut water, shallot extract, bean sprout extract, and bamboo shoot extract. This study aims to determine the effect of various types and doses of organic ZPT on the success and growth of durian grafting and to determine the best ZPT. The study used a randomized block design with five treatments and five replicates. The treatments consisted of a control without PGR, 250 ml/plant of red onion extract, 200 ml/plant of bean sprout extract, 250 ml/plant of coconut water, and 250 ml/plant of bamboo shoot extract. The data were analyzed using ANOVA, and if there were significant differences, they were followed up with Duncan's multiple range test at a 5% level. The results showed that all treatments produced a 100% survival rate. Organic PGRs had a significant effect on the number of leaves and upper stem diameter, but no significant effect on the increase in shoot length and lower stem diameter. Bean sprout extract produced the highest number of leaves, while coconut water produced the largest upper stem diameter. Keywords: cuttings, durian, growth regulators, organic plant, seeds, slits

Abstract

The use of livestock waste as liquid organic fertilizer (LOF) is a sustainable solution for reducing dependence on chemical fertilizers and improving environmental quality. Goat manure has potential as a raw material for LOF because it contains the macronutrients nitrogen (N), phosphorus (P), and potassium (K), as well as microorganisms that play a role in the decomposition process. This study aims to analyze the dynamics of the microbial population (bacteria and fungi), changes in NPK nutrient content, and environmental conditions during the fermentation of goat manure POC. The study was conducted over 21 days at the Biology Laboratory of the Department of Agroindustry, University of Padang, using a completely randomized design with eight fermentation time points and three replicates. Microbial populations were analyzed using the Total Plate Count (TPC) method, while NPK content was measured using a Rapid NPK tester. Data were analyzed using ANOVA and the DMRT post-hoc test at the 5% level. The results showed that fermentation duration had a highly significant effect on microbial population and nutrient content. Bacterial population peaked on day 18, while fungal population was highest on day 15 of fermentation. The highest nitrogen content was obtained on day 21, while phosphorus and potassium were highest from days 18 to 21. The pH value remained relatively stable within the neutral range, and the temperature remained within the mesophilic range, which supports microbial activity. It was concluded that fermentation for 18–21 days produced POC with optimal biological and chemical quality and has the potential to be used as an environmentally friendly liquid organic fertilizer. Keywords: liquid organic fertilizer, goat manure, fermentation, microorganisms, NPK
