Tricahyati, T., Suparman, S., Arsi, A., Hamidson, H., Pujiastuti, Y., Azhari, S.,Apriyansah, Erlangga, E., Agustin, H. M. (2025). Population of Aphis gossypii (Hemiptera: Aphididae) on Chili Pepper Crops in South Sumatera Province. 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).Chili pepper plants (Capsicum annuum L.) have high demand in both local and international markets, contributing to economic stability and food security. However, chili cultivation faces challenges such as climate change and pests. Chili production in Indonesia has experienced a drastic decline, caused by the infestation of the Aphis gossypii pest, which is resistant to insecticides and can cause losses of up to 90% as a disease vector. Therefore, this study aimed to identify the Aphis gossypii population on chili plants, the factors influencing it, and the intensity and incidence of Aphis gossypii attacks in South Sumatra Province. This research was conducted on several chili farming lands in South Sumatra Province. Data collection was carried out by selecting land using the purposive sampling method, then simple random sampling was used when taking samples from the chili fields by randomly selecting 5 ridges and then observing 10 plants from each ridge, resulting in a total of 50 plants observed from each chili field. The results of research conducted in four cities or districts, namely Palembang City, Prabumulih, Musi Banyuasin Regency, and Muara Enim, in South Sumatra Province, found a populationpii) totaling 2949 individuals. Aphid attacks cause chili plants to become paler, with leaves curling, yellowing, wilting, and shrinking. The intensity obtained was mild, between 7.5% and 21.5%. The incidence of attacks was mostly low, with 14-36%. This could be due to the abundant food available for aphid pests.

Arsi, A., Purwitasari, N. A., Suparman, S., Tricahyati, T., Hamidson, H., Pujiastuti, Y., Putra, A. M., Danata, N. H., Amanda, A., Khansa, A. A., Manalu, S. A., & Azzahra, Z. (2025). Percentage of Erionota thrax Attacks on Barangan, Ambon, and Rattan Bananas in South Sumatra. 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).Erionota thrax (L.) is a major pest of banana plants, with damage reaching up to 60%. This study aimed to identify the percentage of leaf damage caused by E. thrax in three banana cultivars: Barangan, Ambon, and Rotan in South Sumatra. This research was conducted using survey and mapping methods by determining coordinate points, specifically the affected plants, and then observing the area around symptomatic plants within a 50-meter radius. The Timestamp application was used for documenting the E. thrax pest. The research results show that E. thax attacks vary across regions and banana varieties. The highest percentage of leaf roller attack rates was found in Muratara Regency, reaching (50%), while the lowest percentage of leaf roller attacks was found in Prabumulih, only reaching (1.06%). The results show that the percentage of Rotan and Barangan bananas is more resistant to the leaf roller pest E. thrax and is not attacked by the banana leaf roller (0%), while the attack percentage on Ambon bananas reaches (50%). This indicates that each type or variety of banana has a different level of resistance, and the environment also affects the level of attack. This attack distribution map can serve as a basis for developing more precise pest control strategies. Selecting cultivars like Banana Rotan is an effective strategy to reduce banana production losses in South Sumatra.

Suparman, S., Arsi, A., Hamidson, H., Tricahyati, T., Pujiastuti, Y., Oktapiarni, W., Ramadhana, T., & Khairani., K. (2025). Occurrence of Banana Bunch Top Disease (BBTD) caused by Banana Bunch Top Virus in Ogan Komering Ulu, South Ogan Komering Ulu, and East Ogan Komering Ulu Districts. 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).Bananas (Musa sp.) are a tropical fruit favored by the Indonesian people and have high economic value, but their productivity is still low due to pest and disease attacks, especially dwarf disease caused by Banana Bunchy Top Virus (BBTV), which can reduce yields by up to 100%. The purpose of this study was to determine the incidence of dwarf disease in banana plants in Ogan Komering Ulu, East Ogan Komering Ulu, and South Ogan Komering Ulu districts. It was implemented in 3 districts located in the South Sumatra region. This research was conducted using the purposive sampling method and mapping by determining coordinate points using a time-stamp camera on banana plantations in districts in South Sumatra. The research results obtained show that the percentage of BBTV attacks in the three districts, namely Ogan Komering Ulu, Ogan Komering Ulu Selatan, and Ogan Komering Ulu Timur, differs. A high percentage of attacks was found in Ogan Komering Ulu district at 57.50%, a moderate percentage of attacks was found in Ogan Komering Ulu Timur district at 29.72%, and a low percentage of attacks was found in Ogan Komering Ulu Selatan at 22.22%. Based on the research conducted, it can be concluded that the highest percentage of banana dwarf disease attacks due to the incidence of Banana Bunchy Top Virus (BBTV) was found in Ogan Komering Ulu district with an attack rate of 57.50%, while the lowest percentage was found in Ogan Komering Ulu Selatan district at 22.22%. The most affected banana cultivar was kepok banana, while the BBTV vector, the banana aphid (Pentalonia nigronervosa), was only found in the Ogan Komering Ulu district area.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Biological control of insect pests using entomopathogens is gaining significant attention. One example is controlling of oil palm’s main pest Oryctes rhinoceros. The use of entomopathogen Bacillus thuringiensis is expected to control this pest. B. thuringiensis bacteria can be propagated in various growth media. The purpose of this study was to examine the growth of B. thuringiensis in various growth media and its effect on the mortality of O. rhinoceros. The study was conducted using a randomized block design, with five treatments and five replications. The five treatments were P1 (rice washing water + cow biourine), P2 (old coconut water + cow biourine), P3 (rice washing water + rabbit biourine), P4 (old coconut water + rabbit biourine). When mortality test was conducted, it was used P0 (water) as a control. The results showed different liquid waste formulations affected  multiplication of B.thuringiensis  after 72 hours. The mixture of rice washing water and rabbit biourine (P3) showed the highest results in producing spores, namely 11.69 x 109 spores/ml. The highest mortality rate was found in rice washing water and rabbit biourine mixture treatment (P3), and the lowest in the control treatment. The highest body length was obtained in the control treatment, which was 9.89 cm, and the lowest one was obtained in treatment P4 (old coconut water + rabbit biourine), which was 4.69 cm.  The lowest LT50 value was 29.51 days and the lowest LT95 value was 65.30 days, shown by treatment P3 (rice washing water + rabbit biourine).

Suparman, S., Arsi, A., Hamidson, H., Tricahyati, T.,  Pujiastuti, Y., Hariyanto, A. M., Putra,A., Khadafi, M. (2025). Intensity of Dwarfing Virus Disease (Banana Bunchy Top Virus) Attack on Banana Gadis in South Sumatera Selatan. 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).Banana plants are horticultural crops that can be developed in Indonesia. However, there are many obstacles in the development process, one of which is an important disease that attacks banana plants, namely Banana Bunchy Top Virus (BBTV). BBTV disease can reduce banana plant production by 10%-30% and can even reach 100%, therefore BBTV disease is classified as very severe. The purpose of this study was to determine the spread of Banana Bunchy Top Virus (BBTV) disease in several regencies/cities in South Sumatra Province.  Field research was carried out from April to October 2023 located in 12 districts / cities in South Sumatra.  Field research applied purposive sampling method with BBTV symptomatic bananas as coordinate points and then photographed using a timestamp camera.  The results showed that in each regency/city in South Sumatra, the number of clumps and the number of stems of pisang gadis were varied and significantly different. The percentage of attack obtained also varied, the highest percentage of attack was found in Banyuasin Regency with a percentage of 18% and the district with the lowest percentage of attack (0%) was found in North Musi Rawas Regency, Lahat Regency, Prabumulih City, and Lubuklinggau City. The conclusion from the Field research is that the distribution of banana girl population in South Sumatra is evenly distributed with the percentage of BBTV attack also evenly distributed in each region.
