Peranan Dark Septate Endophyte dalam Budidaya Tanaman
No full textDark Septate Endophyte (DSE) is a fungus in symbiosis with the host plant and is characterized by the presence of dark pigment, insulated hyphae, and microscleretia. The effect of DSE fungi on the host plant is specific according to the fungal strain, host plant species, and environmental conditions. DSE fungi can colonize host plant roots intra and extracellularly as well as ectendomycorrhiza. In DSE colonization, sometimes it fails to form a dense mantle and hartig net, but instead, it forms melanin microscleretia. The symbiosis between DSE fungi and suitable host plants can increase plant growth, uptake of N and P elements, resistance to drought, extreme temperatures, and protect plants from plant-disturbing organisms. The increase in the uptake of N and P elements was caused by the ability of DSE fungi to produce proteolytic enzymes and phosphatases that can mineralize organic N and P so that they become available to plants. Increased resistance to drought and extreme temperatures is thought to be due to melanin hyphae which can help absorb water from the soil and produce antioxidants and protection against free radicals. In addition, some strains of DSE fungi also produce chlorine to protect plants from plant-disturbing organisms

Identifikasi Senyawa Kimia pada Tanaman Pulai (Alstonia scholaris) Sebagai Pestisida Nabati untuk Pengendali Hama
No full textCurrently, farmers still rely heavily on chemicals in controlling plant-disturbing organisms. This is supported by increasing the number of pesticides registered and circulating in the market from year to year. Based on the principle of IPM (Integrated Pest Management), pesticides are the last alternative if other control methods cannot reduce the pest population. However, the farmers in Compong Village, Pitu Riase District, Sidrap Regency, are still using one of the local wisdom to control pest populations. The pest control utilizes plant parts, one of which is the pulai plant (Alstonia scholaris). However, the use of pulai plant extracts has not been optimal because information on the types of chemical compounds and their functions is not widely known. This study aims to determine the types of chemical compounds in the leaves and stems of pulai plants that can be used as vegetable pesticides. The research was started by making a fine powder from the leaves and stems, after which the extraction was carried out by the maceration technique with methanol for 4×24 hours. The extract was then subjected to a phytochemical test. The test results showed that the leaf extract of the pulai plant contained saponins, flavonoids, and alkaloids. While the stem extract only contains saponins and alkaloids. This result shows that the pulai plant has the potential to be used as an environmentally friendly vegetable pesticide.Currently, farmers still rely heavily on chemicals in controlling plant-disturbing organisms.

Pertumbuhan dan Produksi Dua Jenis Sawi Menggunakan Perbedaan Nutrisi Secara Aeroponik
No full textConsumer demand for mustard needs in Indonesia is increasing. Efforts to produce mustard greens use an aeroponic system to utilize nutrients in dosage and type correctly. The study aimed to determine the proper type of nutrition for the growth and production of two mustard greens in an aeroponic system. This study used a completely randomized design with two factors. The first factor is the type of mustard which consists of two levels, namely pakcoy and pagoda. The second factor to consider is the nutrition applied at three different levels: AB mix, liquid organic fertilizer, and foliar fertilizer. Mustard greens grew and produced significantly differently when grown in an aeroponics system. Other nutrients greatly affected all observed variables, including plant height, leaf number, leaf color, root length, fresh plant weight, and dry plant weight. The use of pakcoy mustard provides the best growth and production of mustard greens compared to pagoda-type mustard. Giving AB mix nutrition to mustard greens can provide the best growth and production compared to nutrition from liquid organic fertilizers and foliar fertilizers. The AB mix nutritional treatment with pakcoy mustard produced the best results in plant height, leaf number, wet weight, dry weight, and root length. AB mix nutritional showing the best leaf color variable with pagoda mustard greens
