Abstract

The transformation of the nest swiftlet house for the cultivation of grey oyster mushrooms is seen as a strategic transition. A few improvements and a little expense given a good value of impact on yield (mushrooms). A total of 119.3 g per bag of grey oyster media produced in the swiftlet house, Sg. Petani, Kedah compared to 149.1 g per media bag in the Environmental Controlled Mushroom House (CEMH), MARDI Headquater, Serdang, Selangor. Although, mushroom yield is higher (CEMH) than swiftlet house but CEMH operating cost is bigger (high electricity consumption). However, there was no significant difference in the yield of mushrooms in the swiftlet house (119.3 g per media bag) with the DANA project mushroom house, MARDI Kedah Office, Alor Setar, Kedah (115.9 g per media bag). Indirectly, giving an entrepreneur a second chance against financial loss.

Abstract

In this research, a viability test was carried out to obtain information about the ability of shallots to germinate under certain conditions. The use of hot water in Murashige and Skog media is a way to obtain information on certain conditions. The aim of this research is to determine the effect of hot water immersion temperature and water soaking time on the viability of shallot seeds (Allium cepa L.) on Murashige and Skog media. This research was carried out at the Alifa Agricultural Research Center (AARC) Laboratory. This research used a completely randomized factorial design (RAL) with two factors, the first factor was hot water temperature with 3 levels, namely: S0 = 27 ? C (control), S1 = 45 ? C, S2 = 60 ? C. The second factor is the length of immersion with 3 levels, namely: L0 = 3 seconds (control), L1 = 10 minutes, L2 = 15 minutes, a combination of 9 treatments which were repeated 3 times to obtain 27 experimental units. The number of samples in each experiment was 3, so the total sample was 81. The parameters measured were the percentage of plumule emergence (%), the percentage of radicle emergence (%), the percentage of live explants (%), the percentage of explants contaminated with bacteria (%), the percentage of explants contaminated with fungi (%), the number of shoots (plants), the height of plants (cm), number of leaves and number of roots. The results showed that the observed heat treatment had no significant effect on the observed parameters of the percentage of explants contaminated with bacteria, the percentage of explants contaminated with fungi, and the number of roots. In the long soaking treatment, it was observed that it had a significant effect on the percentage of live explants. The interaction of temperature treatment and soaking time had a significant effect on the percentage of live explants.

Abstract

Liquid Organic Fertilizer (LOF) obtained of vermicomposting processis an alternative organic fertilizer that has the potential to enhance sustainable plant growth. This study aims to investigate the effects of liquid organic fertilizer vermicompost on the vegetative growth of selected lfruity plant species, as okra (Abelmoschus esculentus) eggplant (Solanum melongena), and white radish (Raphanus sativus). The research was conducted at the Integrated Organic Farm and the Organic Laboratory of the Malaysian Agriculture Research and Development Institute (MARDI) in Serdang, Selangor, Malaysia, during September 2024. The study was carried out in two phases: field trials and laboratory tests. The field trial used a non-factorial Randomized Block Design (RBD) with four treatments, each replicated three times. The treatments of LOF vermicompost were as follows: V1 = 25% LOF; V2 = 50% LOF; V3 = 75% LOF; and V4 = 100% LOF. The laboratory tests utilized a non-factorial Completely Randomized Design (CRD) with eleven treatments, also replicated three times. The treatments were: V0 = Control (no treatment); V1 = 10% LOF; V2 = 20% LOF; V3 = 30% LOF; V4 = 40% LOF; V5 = 50% LOF; V6 = 60% LOF; V7 = 70% LOF; V8 = 80% LOF; V9 = 90% LOF; V10 = 100% LOF. The results indicated that the concentration of liquid organic fertilizer (LOF) vermicompost did not significantly affect the time of plumule emergence, the number of leaves, the fresh weight, and the dry weight in okra, eggplant, and radish. However, a significant effect was observed on plant height growth in the seedling trays. The study showed no significant differences in responses to the concentrations of LOF vermicompost among the three seed types. Nonetheless, white radish (R. sativus) exhibited better growth potential, particularly in plant height in the seedling trays. The concentration of LOF vermicompost did not significantly influence the time of plumule emergence, the number of leaves, and the dry weight in okra, eggplant, and radish. However, significant effects were observed on plant height and fresh weight in the laboratory. Overall, radish (R. sativus) demonstrated the best potential compared to okra and eggplant, especially regarding plant height and fresh weight in the laboratory.

Abstract

Orphanages as Child Welfare Institutions have a very important role in improving children's education, especially life skills as provisions for facing competition in the world of work. The lack of life skills training received by Muhammadiyah Orphanage children due to limited funds is one of the reasons for providing refrigerator service skills training to orphanage children. The choice of refrigerator service training is because almost every household has a refrigerator for storing food and drinks so that they last a long time. This is certainly a market share that is quite promising in providing refrigerator service services. The aim of this program is to provide life skills to orphanage children so that they have the ability to work and become entrepreneurs in providing refrigerator servicing and become a source of income for the orphanage. This method is implemented by providing direct training in the form of theory and practice with training material consisting of refrigerator working mechanisms, introduction and use of the equipment used, and refrigerator repair practices including measuring pressure and electric current, cutting and welding copper pipes, vacuuming and filling refrigerant. as well as compressor replacement. The results obtained by training participants are understanding the working mechanism and the ability to detect damage and repair the refrigerator.

Abstract

  ABSTRAK   Penelitian ini bertujuan untuk mengevaluasi efektivitas ekstrak daun mimba (Azadirachta indica), daun sirsak (Annona muricata), serta kombinasi keduanya terhadap mortalitas dan konsumsi pakan Sitophilus zeamais pada biji jagung selama penyimpanan. Penelitian dilaksanakan di Laboratorium Hama dan Penyakit Tumbuhan, Fakultas Pertanian UMSU, pada Oktober–November 2025 menggunakan Rancangan Acak Lengkap (RAL) dengan tiga ulangan dan empat perlakuan: kontrol, ekstrak daun mimba 10 mL L⁻¹, ekstrak daun sirsak 10 mL L⁻¹, dan kombinasi mimba–sirsak (5 + 5 mL L⁻¹). Parameter yang diamati meliputi mortalitas imago harian selama tujuh hari dan sisa pakan setelah periode pengamatan. Hasil menunjukkan bahwa ekstrak nabati memberikan variasi nilai mortalitas, tetapi analisis ragam menunjukkan pengaruh tidak nyata (p > 0,05). Mortalitas tertinggi terdapat pada perlakuan daun sirsak (53,3%), diikuti mimba (33,3%), kontrol (30%), dan kombinasi (13,3%). Konsumsi pakan juga tidak menunjukkan perbedaan nyata antarperlakuan, dengan rataan sisa pakan berkisar 2,5–5,07 g. Hasil ini mengindikasikan bahwa konsentrasi ekstrak yang digunakan belum mampu menghasilkan efek insektisidal yang signifikan terhadap S. zeamais. Penelitian lanjutan diperlukan dengan konsentrasi lebih tinggi, metode ekstraksi berbeda, atau formulasi stabil untuk meningkatkan efektivitas pestisida nabati pada penyimpanan biji jagung.     Kata kunci: hama gudang, ekstrak daun, Azadirachta indica, Annona muricata

Abstract

The distillation method is one way to produce essential oils from various parts of plants such as flowers, stems, bark and fruit, seeds and roots. This process has the advantage of oil purity and lower costs. The selection of sweet orange peel, kaffir lime peel and grapefruit peel as raw materials for making essential oils is due to their easy availability with fairly good essential oil characteristic quality. This study aims to obtain the best characteristic quality among the three types of peel used so that it is suitable for its use. The characteristics of essential oils analyzed include yield, acidity level (pH), water content, aroma resistance and color. The quality of essential oil characteristics greatly influences the use of essential oils in the industrial world such as food, beverages, perfumes, medicines and cosmetics. Based on the results obtained, kaffir lime peel produced the highest yield of 1.24%, the lowest water content of 9.21 indicating quality essential oil, the highest acidity level (pH) with a pH of 4.59 and a slightly yellowish clear color.
