Dwintha SA, Aji HP, Haraki IM, Syahputri M, Rahman MAN, Puspitasari V. 2021. Botanical traps of clove leaf waste (Syzygium aromaticum) to control of fruitflies (Bactrocera spp.) on chili (Capsicum spp.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 320-328. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The attack of fruitflies (Bactrocera spp.) on red chili plants is one of the most important problem in the red chili production process. Usually, farmers prefer the synthetic pesticides in controlling fruitflies. However, this method has a negative impact, such as resistance and resurgence of the target pest. This review aimed to provide information about the benefits of clove leaf residue's compounds as an innovation by the combined bioattractants through the application of botanical traps in controlling fruitflies. This writing method used an analyzed literature which developed into an understandable review. Clove leaf residue's extraction contained about 70-96 % methyl eugenol. Clove leaf residue's bioattractants could release volatile compounds containing methyl eugenol that was able to attract male fruitflies. The botanical traps system had the ability to attract fruitflies and could be used for a long time. The application of botanical traps caused disruption of sexual communication so that mating disorders occured in fruitflies. The conclusion is that methyl eugenol compound in clove leaf residue could be used as a bioattractant to replace synthetic attractants which combined with botanical traps.

Herlinda S, Sari JMP. 2021. Sustainable Urban Farming: Cultivation of black soldier fly (Hermetia illucens) to produce manure, and fish and poultry feedstuff. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 27-37. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Urban farming in this pandemic era is a necessity for the community because in addition to entertainment, it can also increase income if it is done professionally. Manure and fish and poultry feedstuff can be produced by cultivating black soldier fly (BSF) or Hermetia illucens in the yard using municipal organic waste. This paper aimed to review and come up with ideas on how to cultivate BSF to produce the manure, and fish and poultry feedstuff. Cultivation of BSF was carried out using organic materials or municipal organic waste. BSF has life stages starting from egg, larvae, pupae, and adult stage or fly. In the adult stage, the fly lays eggs next to a food source or organic waste that has pungent smell, then the eggs hatched into larvae. The larvae consumed and decomposed the organic material waste or the municipal organic waste or livestock feces into a final product in the form of organic fertilizer or “kasgot” (=BSF manure). The BSF manure contained nutrients for plants, such as NPK elements. BSF larvae and pupae contained a lot of protein and could be directly used for poultry and fish feedstuff which had high selling value. BSF cultivation was also useful in overcoming the municipal organic waste problems, such as food waste, livestock feces, and other organic wastes. BSF cultivation did not require a large area for farming and could be carried out in the house yard so it was very suitable for urban farming. Thus, this BSF has the potential to be developed to producing the organic fertilizer, it can also produce the fish and poultry feedstuff.

Astiko W, Isnaini M, Fauzi MT, Muthahanas I. 2021. Concentration, nutrient uptake and growth in several soybean varieties with application of mycorrhizal, organic and inorganic fertilizer package in dryland. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 279-288. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The application of inorganic fertilizers with high doses which are usually applied intensively by farmers can inhibit the development of mycorrhizae in the soil. Therefore, in its application it is necessary to set the appropriate dose for the development of mycorrhizae. Likewise, the addition of organic matter can stimulate the development of mycorrhizae in the soil. This study aims to determine the nutrient concentration, nutrient uptake, and growth of several soybean varieties with the application of inorganic fertilizer packages and organic matter and mycorrhizal biological fertilizers in dry land. This experiment used a Randomized Block Design with three replications. The treatment of soybean varieties tested were V1: Anjasmoro variety, V2: Biosoy II variety, V3: Detap variety I, V4: Dega variety I, V5: Dena variety I. The variables observed in this study were: (1) nutrient concentration variables soil (N and P) at 40 days after planting, (2) growth variables included: plant height, number of leaves, dry weight of shoots and roots, plant nutrient uptake at 40 days after planting (N and P), and (3) mycorrhizal population variables included : number of spores and percentage of root infection at 40 days after planting. Observational data were analyzed using analysis of variance followed by the Least Significant Difference test at a significant level of 5%. The results showed that the Anjasmoro (V1) variety showed the best growth in the application of organic, inorganic, and mycorrhizal fertilizers on dry land in North Lombok.
