Nunilahwati, H., Purwanti, Y., Nisfuriah, L., Dali., Kalasari, R., Zairani, FY., Hasani, B., Rompas, JP & Ferdianto, R. (2024). Arthropoda population dynamics in cabbage plants (Brassica oleracea L.) in Kerinjing Village, Pagar Alam City. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 512–522). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Arthropods can affect the economic and ecological success of agroecosystems in cabbage plantations. The study aimed to obtain data on the dynamics and types of arthropods in cabbage plantations. The study was conducted in cabbage plantations in Kerinjing Village, Pagaralam City from June 2024 to July 2024. The method used to determine the types and populations of arthropods was by setting traps on the soil surface and insect nets (sweep nets) for arthropods in the plant canopy. Data were analyzed using analysis of variance (ANOVA) and further Least Significant Difference (LSD) tests at a significance level of 5%. The results of the study found six orders of arthropods, namely Araneida, Coleoptera, Dermaptera, Hymenoptera, Lepidoptera, and Orthoptera. The population of arthropods in each order was found to fluctuate. The highest population in the Dermaptera order was 6.79 individuals, and the lowest in the Araneida order was 0.78 individuals, while in the Coleoptera, Hymenoptera, Lepidoptera, and Orthoptera orders were 0.83, 0.92, 2.46, and 0.93, respectively. Data on the dynamics of diverse arthropod populations can be the basis for determining the timing and methods of environmentally friendly and sustainable pest population control in cabbage plantations.

Sugiarto, M.H., Irsan, C., Warman, A., Laila, M.R., Nuraini, F., Putri, O.A. (2024).Phytophagous and Entomophagous insects on bitter gourd (Momordica charantia L) plants in North Indralaya District, Ogan Ilir Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 843–853). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Phytophagous insects are plant-eating insects or what are usually called herbivores. These phytophagous insects are referred to as pests if their eating behavior on plants causes economic losses. Meanwhile, predatory insects or entomophages are a group of natural enemies that are very important in helping reduce pest populations. This research aims to identify and determine insect species that live on plants or around plants and their role on plants and other insect species. Research was conducted on 2 vegetative and generative bitter melon fields among farmers in North Indralaya District, Ogan Ilir Regency, South Sumatra Province in September 2021. The observation method was carried out using 2 traps, namely the pan trap and the pitfall trap. This observation was carried out every morning at a distance of 12 hours for pan traps and 24 hours for pitfall traps within 1 week. Observations on bitter melon plants show that arthropod species use pan traps. The results obtained were 7 orders, 16 families and 17 species of arthropods on bitter melon plants which were successfully identified using pan traps and 6 orders and 9 families and 8 species of arthropods which were successfully identified using pitfall traps.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 753–761). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The aimed of this research was to analyze the climat for planning the development of planting media designs that are able to adapt to the impacts of climate change. The climate crisis seriously impacts the agricultural sector, such as the threat of flooding and drought. As a form of adaptation to the impact of climate change, the agricultural sector must innovate, one of which is through planting media. It is essential to develop planting media based on climate analysis to provide an excellent opportunity for successful adaptation to the impact of climate change. Climate analysis in a place to support the development of planting media can include analysis of trends in climate variables and estimates of changes in the water balance. Changes in climate variables and estimates of changes in the water balance provide information for the development of planting media designs in an area to avoid the impacts of flooding and drought. Changes in climate variables can provide detailed information on future environmental conditions and changes in plants' availability and needs of water. Specifically, the development of planting media designs can be a determinant of the success of adaptation to the impacts of climate change that are being faced, but planting media designs must be considered based on the results of climate analysis.

Dewi, R.R, Sihombing, J.M., & Ma’arif, I. (2024). A Survey of health manajemen practices on livestock farm located in Binjai, North Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 69–75). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Practicing good health management in livestock is critical in controlling infectious diseases in livestock. This study attempts to evaluate the health management practices implemented by ruminant farmers in Binjai, North Sumatra. The study aimed to was carried out utilizing a survey method combined with interview techniques and field observations. This study included 56 ruminant farmers who raised cattle (37; 66.1%), goats (14; 25%), and sheep (5; 8.9%). The findings of this study revealed that approximately 68% of farmers have implemented sanitation and disinfection on their farms, whereas only a small percentage of farmers have received animal health training (8.9%), and there is little veterinary support in dealing with disease (16.1%). In treating their animals, farmers use anthelmintic drugs about 26.8% and the majority of farmers prefer antibiotics (42.9%) to herbs (7.1%) There is no significance difference between farmers' knowledge about health and sanitation application, veterinarian supports and drugs application among farmers. The majority of Binjai farmers have implemented farm sanitation measures. However, most farmers who have inadequate knowledge of livestock health have no support from veterinarians in diagnosing and treating the diseases. This possibly leads to inappropriate use of drugs by farmers. Farmers in Binjai should receive training regarding livestock health management to elevate a sustainable livestock productivity.

Yakup, Y., Sefrila, M. (2024). The effects of water supplies and mulching intervals on growth and development of upland rice. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 305–312). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Water availability is one of the factors that can influence the productivity of upland rice, so the use of mulch is an alternative that can be applied because applying mulch at certain time intervals can suppress evaporation and support groundwater availability. This research aimed to determine the effect of water provision and mulch application intervals on the growth and development of upland rice. The experiment used a randomized complete block design with two factors and 3 replications.The first factor were water supplies when showed by proportion of field capacity (FC) in some weeks after planting (WAP), i.e. : FC (since 0 WAP); 4/5 FC (0 WAP) and FC (since 2 WAP); 3/5 FC (0 WAP), 4/5 FC (2 WAP), and FC (since 4 WAP); 2/5 FC (0 WAP), 3/5 FC (2 WAP), 4/5 FC (4 WAP), FC (since 6 WAP). The second factor were mulching intervals, i.e.: 0 – 2 WAP; 0 – 4 WAP; and 0 – 6 WAP. The Observations included plant height (2, 4, and 6 WAP), and number of tillers (6 WAP). The results showed that water supply 3/5 FC (0 – 4 WAP) still could be tolerated by early growth of upland rice, but water supply 2/5 FC (0 – 2 WAP) decreased early growth of upland rice significantly. Mulching interval since planting to 4 and 6 weeks after planting able to increased tillers number, while the mulching interval since planting to 2 weeks after planting had no significantly effect on tillers number of upland rice.

Yanti, P. Y., Siaga, E., Meihana, M., & Neksidin, N. (2024). Improving the growth of oil palm seedlings in coal mine ex-soil media through the application of biofertilizers. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 659–666). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's leading plantation commodities. The current extensification efforts of oil palm plantations are positively correlated with the increasing need for quality oil palm seedlings. The most important management practice related to the seedling process is optimal fertilization. This study aimed to determine the growth response of oil palm seedlings in ex-coal mine soil media through the application of biological fertilizers. The research was conducted in Bingin Teluk Village Road, Rawas Ilir District, North Musi Rawas Regency, South Sumatra Province in February-May 2024. This research was conducted using a one-factor randomized group design (RAL) with 4 levels of biofertilizer treatment consisting of control / no treatment (P0), Trichoderma 15g /plant fertilizer (P1), Gliocladium 15g/plant fertilizer (P2), and Mikoriza 15g/plant fertilizer (P3). The results showed that the biofertilizer treatment gave significantly higher results in plant height, number of leaves and leaf area of oil palm seedlings compared to those without biofertilizer treatment. Gliocaldium fertilizer 10g/plant gave the best results on the growth of oil palm seedlings in ex-coal mine soil compared to Tricoderma and Mycorrhiza fertilizer.

Umayya, L.N., Irsan, C., Mulawarman, M., Shobiha, S.N., Fani, G., Apriyani, M., Aulia, H., Mirsya, S.A. (2024). Insects found on duku plants (Lansium domesticum Corr) in Muara Enim Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembangg 21 Oktober 2024. (pp. 212–220). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Cultivation of duku plants has obstacles such as applying of low cultivation technology and interference from Plant Disease Organisms (OPT). Therefore, we need to know the identification of pests that attack duku plants in the area to determine what pest species are causing damage to duku plants. The method used is direct observation and interviews. The results of observations carried out in farmers' duku gardens in Kepur Village, Muara Enim Regency show that insects that have the potential to become pests consist of 6 species, such as red caterpillars, fruit flies, ladybugs, tree termites, plutellidae larvae, and dompolan lice, in contrast other pests attack duku plants are bats and ants. Red caterpillars attack the skin on duku stems, termites attack the lower stems, dompolan lice attack the fluid on the leaves, ladybugs attack young fruit and fruit flies attack the inside of the fruit. Production can be reduced by up to 50-100 kg/stem due to pest attacks on duku plants. Dompolan lice attack duku plants which have a symbiotic relationship with ants. From this description, it was found that tree termite pests are the pests with the highest population and most insects attack the stems of plants. To develop duku production, further research is needed to control pests on duku plants.

Azzahra, A. S., Wulandari, Y. A., & Rais, A. (2024). The dynamic fishing of motan (Thynnichthys thynnoides, Bleeker 1852) and bulan- bulan (Helostoma temminckii, Cuvier 1829) in The Kampar River, Pekanbaru City, Riau. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembangg 21 Oktober 2024. (pp. 563–572). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Motan fish (Thynnichthys thynnoides) and Bulan-bulan (Helostoma temminckii) are fish that have economic value as food fish for the people of Pekanbaru City, Riau. This fish is often caught in canals, oxbows, swamps in the waters of the Kampar River, and one of them is located in the swamps and lakes of Buluh Cina Village. The aim of this research was to evaluate the mortality rate and level of exploitation of the moltan and lunar fish populations in the waters of the Kampar River. This research was carried out from April to October 2021. The research method used an observation method where samples were obtained from fishermen's catches whose length values were measured every month. Data analysis was carried out with the help of FiSAT II software. The results of analysis using FiSAT II showed that for motan fish the total mortality value (Z) = 1.41; natural mortality (M) = 1.1; fishing mortality (F) = 0.31; and exploitation rate (E) = 0.22. In lunar fish the total mortality value (Z) = 3.33; natural mortality (M) = 1.12; fishing mortality (F) = 2.21; and exploitation rate (E) = 0.66. The exploitation level value shows that lunar fishing has experienced overfishing (E>0.5), while exploitation of motan fish can still be increased (E<0.5).
