Get PDFAgustin NA, Syafutri MI, Yanuriati A, Malahayati N, Aryani D, Airlangga T. 2022. Decreasing oxalate levels of taro beneng (Xanthosoma undipes K. Koch) starch at various NaCl concentrations and soaking time. In: Herlinda S. et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 199-207. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Starch is a group of polysaccharides composed of amylose and amylopectin. Taro beneng (Xanthosoma undipes K. Koch) is one of local commodity tubers that has the potential to be used as starch. The problem with taro beneng is content of oxalate which is in water soluble (oxalic acid) and insoluble (calcium oxalate) forms. This study aimed to determine the effect of NaCl concentrations and soaking time on reducing oxalate levels and oxalate reduction values of taro beneng starch. This study used a Factorial Completely Randomized Design (CRD) with two treatment factors, namely NaCl concentrations (5%; 7.5% and 10%) and soaking time (30 minutes; 60 minutes and 90 minutes). The results showed that the difference in NaCl concentrations and soaking time had significant effect on the decrease in oxalate levels and the increase in oxalate reduction values of taro beneng starch. Taro beneng starch soaked for 90 minutes in 10% NaCl solution was the best treatment, because it had the lowest oxalate level (2700 ppm) and the highest reduction value (93.18%)

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 722-735. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The productivity of food crops and horticulture in human needs is threatened due to attacks by pests and pathogens with a total global loss around 50 up to 80%. Continuous application of pesticides in control negatively affects pest resistance, pollutes soil, water, biota, also on farmers and consumers health. This review aimed to summarize the potential of endophytic fungi that are useful as biocontrol agents and growth promoters of food and horticulture crops in suboptimal land. It is suspected that endophytic fungi in horticultural crops are the most widely reported as biocontrol agents and plant growth promoters. The scope of this paper is limited to review scientific articles based on data exploration of endophytic fungi (biology, isolation, and identification of endophytic fungi), their biological activities, and growth promoters in increasing crop productivity. Endophytic fungi are important components of plant micro-ecosystems that are widely found in healthy plant tissues such as the genera acremonium, cladosporium, beauveria, metarhizium, muscodor, periconia, ampelomyces, chaetomium, cryptosporiopsis, nodulisporium, penicillium, phomopsis, and others. Endophytic fungi produce excellent metabolites as biocontrol and growth promoting agents such as antibiotics, antivirals, antiprotozoal, antiparasitic, antioxidant, and immunosuppressant compounds that can be utilized for agricultural and food industries. More than 100 species of endophytic fungi have been reported worldwide as biocontrol and plant growth promoters. Based on the literature review, it can be concluded that endophytic fungi have great potential as biocontrol agents and growth promoters of food crops and horticulture in suboptimal land farming in a sustainable manner

Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Rice (Oryza sativa) is one of the plants that is an important commodity in Indonesia, various efforts have been made to increase rice production, but often encounter obstacles, one of which is the presence of organismal pests, especially insects. Therefore, it’s necessary to have the role of natural enemies in the form of predatory insects in controlling rice pests. This study aimed to determine the number and types of predatory insects found in rice plants in three villages, namely Muara Penimbung Village, Tanjung Sejaro Village, Sakatiga Village, Indralaya District, Ogan Ilir Regency, South Sumatra. This research method was carried out by observing and using yellow traps installed in the rice fields to catch predatory insects. From the research results in the three villages, there are predatory insects with four different orders, namely the order Odonata, order Coleoptera, order Hemiptera, and order Diptera. The order Odonata (dragonfly) consists of 4 species: Pantala flavescents, Orthetrum sabina, Agriocnemis minima, Orthetrum Chrysis. Then the order Coleoptera (beetle) found consisted of 4 species: Epilachna admirabilis, Paederus fuscipes, Micraspis discolor, Diekeana admirabilis. order Hemiptera found 1 species, namely: Andrallus spinidens. One species of the order Diptera, namely: Asilidae sp. So, it can be concluded that predatory insects on rice plants are very diverse and consist of various orders that can be used as natural enemies to control insect pests or plant pests. Further education is needed about the important role of predatory insects as natural enemies of plant pest control.

Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Providing organic fertilizer is important for shallot plants (Allium ascalonicum L.) because organic fertilizer has advantages compared to inorganic fertilizer, namely that it is more environmentally friendly and safe when applied to soil media. One type of organic fertilizer that is often used by farmers is chicken manure. Chicken manure contains quite high levels of nitrogen, phosphorus and potassium nutrients which are useful for shallot plants. This research aimed to determine the best dose of chicken manure for the growth and yield of shallot plants (Allium ascolanicum L.) of the bauji variety. The research was carried out at the Sriwijaya University Campus Experimental Garden, South Sumatra at the coordinates 3 13'29.74”S 104 38'54.13”E which was carried out in June-August 2023. The design used was a Randomized Block Design (RBD) with 3 replications. The dose of chicken manure used is 10 tons/ha (40 g/polybag); 20 tons/ha (80 g/polybag); 30 tons/ha (120 g/polybag) and without chicken manure as a control. Parameters observed included leaf length, number of leaves, number of tillers, leaf greenness level, total chlorophyll content, leaf area, root length, number of tubers, tuber diameter, tuber length, tuber volume, fresh weight of tubers, dry weight of tubers, fresh weight, bushmeat and dry weight of bushmeat per plant. The results of the study showed that the application of chicken manure had a significant effect on the growth and yield of shallot plants. Giving chicken manure at a dose of 120 g/polybag resulted in better number of leaves, leaf greenness, leaf area, number of tubers and tuber production compared to giving other doses of chicken manure

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 439-446). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Water sources that are close to landfills have the potential to be polluted by leachate from landfills and if it enters rice field irrigation channels, it will pollute agricultural products. This study aimed to determine the potential of acid-activated corn cob adsorbent in absorbing Fe metal in rice field irrigation water sources around Pakusari Jember landfill, as well as the effect of acid addition and activation time on adsorbent absorption. The research was conducted using nitric acid activator with variation of activation time ranging from 1 - 4 hours. The effect of acid activation time on mass gain and Fe content of adsorbent was analyzed using analysis of variance (ANOVA). The results of this study indicate that acid-activated corn cob biosorbent causes the number of active sides on the adsorbent to become more so that after activation it is able to absorb metals. Activation time for 2 hours is the most optimal variation because it absorbs Fe metal with the highest level of 2.14%. At 3 - 4 hours of activation, the desorption process occurs so that Fe levels are lower. All four samples have Fe levels that exceed the Ministry of Health's recommendation so it is recommended to do water treatment first before being used for irrigating rice fields
