In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembangg 20 Oktober 2025. (pp. x–y). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Teratak Buluh Market is one of the largest freshwater fish marketing and landing locations, particularly for fish caught in the Kampar River, in Riau Province. Freshwater fish production is influenced by seasonal fluctuations, both rainy and dry seasons. The impact on the effectiveness of fishing gear and the distribution of fish species is primarily affected by rainfall in a given area. The aimed of this paper was to provide an overview of the fish catch production landed at Teratak Buluh Market, Riau, in relation to rainfall fluctuations. This research was conducted by recording the fish products marketed by two enumerators who work as fish collectors at Teratak Buluh Market. The data collected included the total amount of fish marketed, the types of fish traded, and the price per commodity each day over a period of ten months. Additional data collected included rainfall data obtained from the BMKG website of Riau Province. Data analysis was carried out by tabulating and presenting the data in graphs, while the correlation was tested using a t-test. The highest fish production occurred in March with 10,714 kg, and the lowest in May with 6,225 kg. The most marketed product was snakehead fish (Channa striata) with a total of 11,036 kg. The highest rainfall reached 19.85 mm in April, and the lowest was 8.46 mm in September. The correlation between total fish production and rainfall was obtained through the t-test, with a P value of 0.000986 (P<0.05), indicating a significant correlation between production and rainfall levels

The Effectiveness of Fungi (Arthrobotrys sp.) in Controlling Root Knots (Meloidogyne sp.) on Tomato Plants (Solanum lycopersicum). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Root-knot nematode infection by Meloidogyne sp. is a major constraint in tomato cultivation, requiring sustainable and environmentally friendly control measures. This study aimed to evaluate the potential of the fungus Arthrobotrys sp. as a biological agent for controlling these nematodes. The study was conducted from August to October 2022 at the Nematology Laboratory, Department of Plant Pests and Diseases, Plant Protection Study Program, Faculty of Agriculture, Sriwijaya University. The study used a completely randomized design (CRD) with four treatments: Control, Arthrobotrys sp. (granules), Arthrobotrys sp. Liquid, and Carbofuran Nematicide, each with five replicates on tomato plants of the Sarvo variety infected with root knot nematodes. The data obtained were analyzed using analysis of variance (ANOVA). The results showed that the application of Arthrobotrys sp. was able to increase plant growth and significantly reduce disease severity, the number of root galls, and the number of nematode eggs (p<0.03) compared to the control. Analysis of variance confirmed the effectiveness of this fungus in inhibiting nematode development, especially in reducing egg mass and disease severity, although its effect on other growth parameters was not significant. Thus, Arthrobotrys sp. has the potential to be developed as a biological control agent for root-knot nematodes in tomato plants and can provide important information for farmers in overcoming nematode attacks on tomato plants (S. Lycopersicum)

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembangg 20 Oktober 2025. (pp. x–y). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Parijoto fruit is a herb that can be used in animal husbandry as a feed additive. Parijoto fruit contains flavonoids, antioxidants, and saponins, which can protect body cells and tissues from free radicals. This study aimed to assess the effect of microencapsulated parijoto fruit extract-Lactobacillus plantarum (MPFE-Lp) on fat digestibility and meat fattening in broiler chickens raised at high densities. The experimental chickens used were 308 unsexed Ross strain broilers, 8 days old, with an average body weight of 208.42 g. Microencapsulated parijoto fruit extract-Lactobacillus plantarum served as a combination of phytobiotics and probiotics. The feed ingredients included yellow corn, rice bran, soybean meal, fish meal, limestone, premix, lysine, and methionine. The study was designed using a completely randomized design with 3 treatments and 7 replications, resulting in 21 experimental units. The treatments applied included T0 = chickens raised at normal density (10 chickens/m2) without 0.6% MPFE-Lp, T1 = chickens raised at high density (17 chickens/m2) without 0.6% MPFE-Lp, and T3 = chickens raised at high density (17 chickens/m2) with 0.6% MPFE-Lp. The parameters measured included fat digestibility, meat fat mass, and relative abdominal fat weight. Data were processed using analysis of variance at a 5% significance level. If a significant effect was found, a Duncan test at a 5% level was used to determine differences between treatments. The results showed that the addition of 0.6% MPFE-Lp to the ration had a significant effect (p<0.05) on fat digestibility and fatty meat of broiler chickens raised at high density. The conclusion of the study is that the addition of 0.6% MPFE-Lp to the ration can reduce fat digestibility and fatty meat of broiler chickens raised at high density

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Rice (Oryza sativa L.) is often damaged by insect pest attacks. This study analyzes the distribution of insect pests that cause damage to rice fields due to six types of pests brown planthopper, green planthopper, white stemborer, yellow stemborer, armyworm, and leaf folder in Thai Nguyen Province, Vietnam. The research was conducted from April to September 2024 using calculations of diversity index, evenness, dominance, abundance, as well as correspondence and cluster analysis of the insect pests. Data on the damaged area in hectares was collected from the districts of Dinh Hoa, Dong Hy, Phu Binh, Phu Luong, Vo Nhai, Dai Tu, and Thai Nguyen. The results showed that the leaf folder was the most destructive pest, particularly in Thai Nguyen district, causing damage to up to 156 hectares. Other districts experienced more evenly distributed damage, with the highest values ranging from 10 to 25 hectares caused by various pests. These findings highlight that pest management strategies must be specifically tailored. It can be concluded that the distribution of insect pests across the districts is uneven, with the leaf folder being the most dominant, the green planthopper having high diversity but low dominance, the yellow stem borer being evenly distributed, and the armyworm being the most unique. Cluster analysis revealed similarities in pest characteristics and proximity between districts, which is important for developing more effective and targeted pest control strategies

No full textPadang, T. V., Irmawati, I., Susilawati, S., Kurnianingsih, A., Halimi, E.S., Andini, W., & Amiros, N. (2025). The Effect of Naphthalene Acetic Acid in Murashige and Skoog Medium on Durian Leaf Callus Induction. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Durian is a key commodity with high economic value in South Sumatra, but the generative propagation of this plant still faces obstacles. This research aimed to determine the effect of NAA (Naphthalene Acetic Acid) application in MS (Murashige and Skoog) medium on callus induction in durian leaf explants (Durio zibethinus Murr.). The research used a completely randomized design (CRD) with five levels of NAA concentration, namely N0 = 0 ppm, N1 = 1 ppm, N2 = 2 ppm, N3 = 3 ppm, and N4 = 4 ppm, each repeated three times with each unit consisting of 10 culture bottles. The research results showed that the N0 treatment produced 83% live explants with 16.7% contamination, N1 produced 13% callus growth with 36.7% contamination, while N2 produced 80% live explants, 20% callus growth, and 20% contamination. Treatment N3 had the highest contamination at 73% with 26.7% live explants, while N4 produced 100% live explants but only 6.7% callus growth. During the 8-week observation period, the highest callus formation occurred in treatment N2. This research concluded that low NAA concentrations in the range of 1–2 ppm are more optimal for inducing callus in durian leaf explants, while excessively high NAA concentrations inhibit callus formation and increase the risk of contamination. These results can be used as a reference in optimizing durian tissue culture media to accelerate vegetative propagation and support the development of tissue culture techniques in woody plants

Sinergi Gula Nusantara. In: Herlinda, S et al.(Eds). Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x-y). Palembang: Penerbit & Pencetakan Universitas Sriwijaya (UNSRI).Sugarcane (Saccharum officinarum L.) is an annual crop that grows well in tropical and subtropical regions. It is a unique plantation crop because its stalk contains sugar, which serves as the main source of sugar production worldwide. This study aimed to examine land management techniques and the effectiveness of filter cake compost on soil quality at PT. Sinergi Gula Nusantara. The research was conducted in June–July 2025 at PT. Sinergi Gula Nusantara Cinta Manis, Ogan Ilir Regency, South Sumatra. The research method used was observation, carried out through direct interviews with relevant parties. The results showed that land management practices at PT. Sinergi Gula Nusantara include plane cane, land preparation, and ratoon care, where each stage involves processes from land clearing to post-harvest management. The application of compost made from bagasse mixed with molasses and ash contributed to improving soil aggregate stability. Although bagasse compost did not significantly affect the availability of macronutrients, it showed a positive impact on improving soil physical properties. Bagasse is one of the by-products of sugarcane processing that can be utilized as compost. It can be applied to the soil by mixing it with molasses and ash, all of which are by-products of the sugar industry. Bagasse compost is best applied before land preparation, allowing it to decompose more effectively

Population and Mortality of Plutella xylostella Pests on Cabbage Leaves Treated with Monosodium Glutamate and Botanical Insecticide of Neem Extract. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Cabbage (Brassica oleracea var. capitata L.) is one of the important horticultural commodities that is highly susceptible to Plutella xylostella infestation, which can significantly reduce crop yield. This study aimed to evaluate the effectiveness of a mixture of monosodium glutamate (MSG) and neem extract in suppressing the population and increasing the mortality of P. xylostella on cabbage plants. The research was conducted from April to September 2024 at the Thai Nguyen University of Agriculture and Forestry (TUAF) using a Randomized Block Design (RBD), with grouping criteria based on the uniformity of environmental conditions, including light intensity, temperature, and soil humidity, to minimize environmental variation effects on observations. The experiment consisted of six treatments: E+MSG 0 (control), E+MSG 1 (0.1 mg), E+MSG 2 (0.2 mg), E+MSG 3 (0.3 mg), E+MSG 4 (0.4 mg), and E+MSG 5 (0.5 mg), each replicated five times. Data were analyzed using inferential statistics to determine the effect of treatments on pest population and mortality. The results showed that in the control treatment, the average P. xylostella population reached 35 individuals per plot with approximately 29 individuals in mortality, while the E+MSG 1 and E+MSG 2 treatments were the most effective, reducing the population to 3 and 11 individuals, respectively, with higher mortality rates than other treatments. Therefore, the combination of MSG and neem extract has the potential to serve as an environmentally friendly pest control alternative, reducing dependency on synthetic chemical insecticides
