Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Horticultural crops are an important component in agriculture that has several types such as the cultivation of vegetable crops, fruits, flower plants, and medicinal plants. One of the causes of low productivity of horticultural crops is due to the attack of plant pest organisms (OPT). To control the damage to the crops, farmers use synthetic pesticides. The aimed of study was carried out to identify insect pest species in horticultural crops in Paal Merah sub-district and Sungai Gelam sub-district, Jambi. The data obtained was using the purposive sampling method and 36 sample plants were taken using sampling intervals. The results obtained by some farmers aged 40-50 years with an average level of elementary education. Data from interviews with 10 farmers using pesticides and observation of the intensity of pest attacks was 23.47% and disease was 37.78%. Pests that attack horticulture are Liriomyza sp., Aulacophora indica, Spodoptera litura, Bactrocera sp., Rattus argentiventer., Sanurus indecora., and Tetranychus sp. Diseases that attack are leaf spot, anthracnose, fruit rot, and orange black spot

Get PDFShadila, T.A., & Jubaedah, D. (2024). Aplication of starvation and fermented feed on growth and feed conversion ratio of tilapia (Oreochromis niloticus). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 135–142). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).One of the methods that can increase the growth of culture tilapia is by applying a combination of the starvation method and feed fermentation. The results of previous studies showed a high increase in fish growth when fish are starvated and fed fermented feed compared to the growth of fish without starvated and fed non fermented feed. The purpose of this activity was to determine the growth and feed conversion ratio of tilapia (Oreochromis niloticus) that were starvated and fed fermented feed at Kelompok Pembudidaya Ikan in Tanjung Seteko, Indralaya, Ogan Ilir. Fish rearing for 28 days. Fish stocked in 2 nets (size 0,5 m ´ 0,5 m ´ 0,65 m) that were placed in concrete pond (size 5 m ´ 4 m ´ 0,7 m). The first pond (K0) as control (without starvation and fed by commercial feed) and the second pond (K1) as treatment (starvated and fed by fermented feed). The parameters were absolute growth of weight and length, feed conversion ratio, and survival rate. Water quality measurements were temperature and pH. The results showed that absolute growth of tilapia that were starvated and fed by fermented feed were higher than those were not starvated and fed by commercial feed. Fish that starvated and fed by fermented feed produced an absolute weight growth of 7.14 g, absolute length growth of 2.34 cm, feed conversion ratio of 1.4, survival rate of 93.3%, and water quality in fish ponds were pH of 7.3-8.3 and temperature of 25.4-31.7℃

Get PDFDestri, E., Rejo, A., Hanum, L. (2024). Determination of tempeh wastewater management model in plaju ulu with interpretive structural modeling method. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembangg 21 Oktober 2024. (pp. 409–425). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The development of the household-scale tempeh industry in Plaju Ulu, Palembang, produces wastewater that has the potential to disrupt environmental balance if not managed properly. This research aimed to establish appropriate recommendations for a model of wastewater management for tempeh to minimize the impacts caused by waste disposal. This study uses the Interpretive Structural Modeling (ISM) approach to determine the relationships between elements in formulating the model recommendations. The framework variables for this research include three main elements: the background conditions of education, economy, and socio-cultural aspects of tempeh producers. The research findings indicate that the implementation of wastewater management for tempeh in Plaju Ulu needs to be supported by strengthening formal education through workshops or seminars for tempeh producers on effective waste management techniques, or by collaborating with academics to develop innovative waste processing technologies. The success of waste management also relies on the welfare of tempeh producers, necessitating efforts such as product diversification from wastewater raw materials and providing access to product certification to enhance competitiveness and sales. Additionally, the management of tempeh liquid waste requires the development of local regulations governing the disposal and management of wastewater, involving tempeh associations in discussions to ensure that the management stages are accepted and implemented effectively. A model for managing tempeh wastewater that focuses on education, economy, and socio-cultural aspects is expected to create a sustainable environmental system through good collaboration among all partiesn.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 768– 777). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The use of predators as biological pest control agents must consider various ecological and biological factors of the predator, one of which is the characteristics of predation which can later provide information for field applications. The aimed of this study was to observe the characteristics of predation of several types of predators on the density of Rophalosiphum maidis prey. This study was conducted using three types of predators, namely Ischiodon sp. larvae, larvae and adult of Coccinella sp. with 5 levels of prey abundance, namely 5, 10, 15, 20 and 25 aphids. The observations made were the duration of searching and handling prey and the functional response of each predator tested. The results showed that the searching and handling time of prey by the three predators increased as the abundance of the prey population increased. Functional responses of predator larvae Ischiodon sp., larvae and imago Coccinella sp. to prey density level treatments varied based on observation time, the type of functional response was the linear type (1st type), exponential type (2nd type) and sigmoid type (3rd type). The predation ability of the three types of predators on aphids increased along with the increase in prey population and observation time. Ischiodon sp. larvae and the adult of Coccinella sp. more effective compared to the larvae of Coccinella sp. in preying on aphids because they have a faster searching and handling time along with increasing prey density

In: Herlinda S et al.(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 383–388). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Coconut is a plant often used by people as a source of life. Coconut is an important contributor to food security at the agricultural level and has high added value at the industrial level. The health of the plants influences the growth and high production of coconut plants in the field during the nursery period. Farmers know three systems or techniques for breeding systems. Each breeding system has advantages and disadvantages, but it is unknown which produces the best plant growth in the main nursery. This research aimed to determine the breeding system that makes the best coconut plant growth in the nursery. The research at the Mapanget Temptation Garden, Palm Plant Research Institute, was conducted for 7 months, from July 2021 to January 2022. The research was conducted using a completely randomized design with 3 treatments and 3 replications. So that 9 experimental units were obtained, and each experimental unit consisted of 8 plants, so 72 plants were needed. breeding using polybags, in land with close planting distance, and in land with sparse planting distance (spaced). The variables observed were plant height and stem diameter. Based on the research results on plant height parameters, significantly different results were obtained. It can be seen that the nursery system rarely shows higher values compared to other treatments 2 to 6 months after treatment (mat). In contrast, the stem diameter parameter shows results that are not significantly different in all treatments

Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Black rice had the disadvantages of high habitus, low productivity, and no soaking resistance. The purpose of this study was to determine the yield potential of black rice crosses with Inpara 5 varieties, especially on submerged land in South Sumatra. This field practice was carried out in South Sumatra Province. Field practice research on plant production was selected from the results of submerged stress tests, in testing plant growth and production the method used was Randomize Group Design (RDG). The results of research on submerged stress testing include the response of several black rice accessions to submerged stress, with measurements of parameters such as plant height, number of tillers, and chlorophyll levels before and after submersion for 14 days of submision. The results showed that plant height increased significantly from an average of 57.84 cm at 20 DAT (Days After Trasplatnting) to 83.93-96.00 cm at 49 DAT with accession I recording the highest height. The number of tillers decreased after submergence stress, with the highest average at 2.90 before submergence and the lowest at 1.29 at 49 DAT, while chlorophyll levels showed little change. In the final observation, accession H showed superior results in production parameters, such as number of panicles, total grain weight, and number of full grains, making it the most productive accession compared to others. In general, all accessions used in this study have the potential to be developed into new varieties of submergence-tolerant black rice. Based on the results of the study, it is suggested that better plant breeding can be done on black rice that shows the best resistance to submergence stress

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 679–689). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Storage insects provide a substantial risk to food spoiling, potentially resulting in a considerable reduction of up to 82.5% in food preservation. Ventilation is essential to avert harm caused by storage insect infestations. This study aimed to identify species and assess the population of storage pest insects in relation to the kind of ventilation in the Alang-Alang Lebar and Sukarame market's storage facilities. This study employed a direct collecting strategy for insects spotted on each food product commodity through handpicking, followed by the identification of each obtained sample. The identified bug species vary due to the diversity of dietary products. Species such Sitophilus oryzae and Tribolium castenum were predominant, alongside several others such as Cryptolestes ferrugineus, Carpophilus dimidiatus, Callosobruchus chinensis, Rhyzopertha dominica, and Oryzaephilus surinamensis. In the rice commodities market in Alang Alang Lebar District, the storage pest species S. oryzae was identified. S. oryzae is an insect pest that inflicts damage on stored rice. Sitophilus oryzae was found as the insect pest responsible for the majority of damage to stored rice. The peanut commodities in the Kebun Bunga Market and KM 5 Market comprised the species C. dimidiatus. C. dimidiatus was a significant pest that infests dry grains and fruits after harvest. The yield loss resulting from the assault of C. dimidiatus was quite substantial. Fermented peanut products were found as the primary target of C. dimidiatus. Seven species were identified in the storage with filtered ventilation. The pest insects infestation was deemed low due to the relatively small population, indicating the efficacy of both natural and filtered ventilation systems

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 918–928). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Swampland has great potential to be planted, but it is often difficult to make full use of it due to watery environmental conditions and unstable soil. In an effort to increase agricultural productivity, optimizing the use of swamp land is an urgent need. One approach that can be done is to implement an efficient and targeted irrigation system. This study aimed to find out and study how swamp land optimization uses irrigation systems and study the problems and obstacles faced when optimizing swamp land using irrigation systems in Bangka Regency. The method used in this study is an observation method which includes direct observation in the field, interviews with staff, and data recording. The conclusion of this study is that the rice field in Banyuasin Village covers an area of 80 ha with 6 ha being forests and swamps. However, with the existence of swamp land optimization activities, it can increase the planting area by 26 ha so that there are 100 ha of rice paddy land that can be planted with rice, The problems experienced in swamp land are often flooded if it rains excessively and drought if it is dry season, The obstacles faced are, the development of irrigation canal infrastructure which is still not comprehensive in the rice fields of Banyuasin Village, Where it is still in the form of soil excavation only so that water has not optimally flowed to the rice field map. The strategy carried out to overcome these obstacles is to build permanent irrigation canals and reclaim irrigation and drainage canals that have been carried out by the Bangka Regency Food and Agriculture Office
