Ningrahayu, S., Herlinda, S., Yulistin, E., Setyawati, A., Anggraini, E., Herwanti,  A. A., Ilmawan, K., Gemala, P. A. N., Maryati, M., Carsilladepasha, F. A. (2024). Population and storage pest spesies from four local markets with various roofs and floors in sub-district of Ilir Timur I, Palembang South Sumatra. In: Ningrahayu et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 823–835).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Food products are agricultural goods imported from overseas and held for extended durations in local warehouses, resulting in pest infestations that cause a yield weight loss of 10.73%. This study aimed to ascertain the prevalence of pest insects in warehouses across several markets in Palembang City. The methodology employed in this observation involved sampling, direct field surveys, and identification utilizing the texts "Insects of Stored Grain" and "Insects of Stored Products" by David Rees. The survey results indicated that seven species of barnyard insects were identified in several markets within the Ilir Timur I Sub-district of Palembang. Pest insects from the warehouse, acquired via purposive sampling, were classified as storage pests that infest food products, including: Tribolium castaneum, Sitophilus oryzae, Oryzaephilus surinamensis, Carpophilus dimidiatus, Rhyzopertha dominica, Cryptolestes ferrugineus, and Callosobruchus chinensis. Disorganized storage facilities with concrete roofs and cement flooring exhibited elevated populations of insect pests. Storage utilizing a high-positioned fiber ceiling, and a ceramic floor can diminish the incidence of insect infestations. S. oryzae, the predominant storage pest insect, exhibits the maximum population density in rice commodities. R. dominica was found with the lowest population density. Future research need data regarding the storage conditions.

Abstract

Manambangtua, A. P., & Hidaya, T. S. (2024). The effect of some breeding systems on the growth of tall coconut (Cocos nucifera) in the nursery. 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.

(pp. 731–742).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).There are many factors that prevent Indonesia from exporting mustard fruits to other countries, one of which is that mustard fruits spoil quickly. Mustard fruit is an agricultural product that cannot be stored for a long time, so it is at high risk in marketing. This field practice aimed to identify insect species found on mustard fruit in the ATC (Agriculture Training Center) field and in places overgrown with mustard fruit inside the Sriwijaya University Indralaya campus. This field practice uses direct survey methods and insect identification using the Google Picture Insect application. The results showed that 4 different orders and 7 different families were found. The insect orders are Diptera, Hemiptera, Hymenoptera, and Lepidoptera. For the Diptera order, 2 families were found, namely D. melanogaster from the Drosophilidae family and B. dorsalis from the Tephritidae family. The Lepidoptera order also found 2 families, namely O. subnotata from the Erebidae family and L. omnivora from the Psychidae family. As for the other 3 orders, each insect order only found one family. Of all the insects identified, C. pennsylvanicus and P. manihot were the two most common insect species found on the three observed sawo plants. The number of fruit flies found on sawo plants was 83, the intensity of attack on sawo fruits was up to 29.61%. Based on the results found there are 7 species of insects and 1 species of spiders that are found to live in mustard plants. The 7 insect species are Drosophila melanogaster, Bactrocera dorsalis, Phenacoccus manihot, Tartessus ferrugineus, Camponotus pennsylvanicus, Orvasca subnotata, Liothula Omnivora, and the spider species found is Telemonia dimidiate. The ant species Camponotus pennsylvanicus can be found in all parts of the sawo plant. Insect species in the ATC field included B. dorsalis, P. manihot, C. pennsylvanicus, and O. subnotata. And one spider species found in the ATC field is the spider species T. dimidiata. Meanwhile, at least 3 insect species were found in fisip fruit plantations. Insect species found in fisip fruit plantations are D. melanogster, T. ferrugineus, and L. omnivora.

Abstract

Laela, F., & Ammurabi, S.D. (2024). Utilization of Ornamental Plants as Phytoremediation Agents to Reduce Lead (Pb) Contamination in Urban Area. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 48–58).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Lead (Pb) is one of common heavy metal pollutant that produced from human activities. Lead pollution produced from fuel, mining activities, fertilizer, pesticides application, and industrial activities that contribute to urban pollution level. Lead concentration in soil cause health problems such as digestive disorders, kidney disease, anemia, and decrease of intelligent quotient (IQ) score. High concentration of blood lead level caused negative health impacts such as increase of cardiovascular diseases, kidney failure, blood anemia, loss of vision, and  bones impair development. Recent science development has given us several alternatives to reduce lead contamination in water and soil, one of which is phytoremediation. Phytoremediation is a process of soil and water decontamination from hazardous substances with plants. Ornamental plants become alternative method of lead phytoremediation because it is unconsumed by human and animals as well as served decorative function. In this paper, various ornamental plant species that show a high capacity to tolerate, accumulate, and improve contaminated soil of lead will be described. Plants with lead phytoremediaton abilities could become solution for urban green space utilization in Indonesia. The purpose of this paper was to determine the types of ornamental plants that can be used as phytoremediators for lead (Pb) contamination in urban areas and to determine the mechanism process.

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 281–292).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This research aimed to determine the effect of filtration and pectin concentration on the physical, chemical, and sensory characteristics of durian skin albedo jam. This research used a Factorial Completely Randomized Design with two treatment factors. The first treatment (factor A) was filtration which consisted of two treatment levels (filtration and without filtration), the second treatment (factor B) was pectin concentration which consisted of four treatment levels (0%, 0,5%, 1%, 1,5%). Each treatment was repeated three times. Parameters observed in this research included physical characteristics (color L* a* b*, viscosity, and spreadability), chemical characteristics (water content, total dissolved solids, pH, and crude fiber), and sensory characteristics (texture, taste, and color). The results showed that the filtration treatment had a significant effect on lightness, yellowness, viscosity, spreadability, water content, and crude fiber, while the pectin concentration had significant effect on lightness, viscosity, spreadability, water content, pH, total dissolved solids, and crude fiber. The interaction between of the two factors had significant effect on viscosity and crude fiber of durian skin albedo jam. The best treatment in this study was the A1B4 (filtering and pectin 1,5%) with a lightness (69.94), redness (4.65), yellowness (10.67), viscosity (316.67 dPa.s), spreadability (25.50 cm), water content (33.48%), pH (3.87), crude fiber (2.53%), sensory texture (2.88), taste (2.96), and color (2.72).

Abstract

Wisaksono, M. A., Tamrin, T., Pratama, F. (2024). The utilization of fiber tissue as an electrolyte absorbent of Dye Sensitized Solar Cell. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 634–648). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Dye-Sensitized Solar Cells represent a set of photoelectrochemical solar cells capable of converting light energy into electrical energy by harnessing plant-derived dyes as light sensitizer. One of the factors influencing the performance of a DSSC is the electrolyte. The addition of a fiber tissue layer to DSSCs can reduce evaporation in the electrolyte solution. The fiber tissue layers used in this study were derived from facial tissue. The objective of this research is to study and understand the impact of varying thicknesses of fiber tissue layers as electrolyte absorption media on the performance of Dye-Sensitized Solar Cells. This research was conducted from September 2023 to December 2023 at the Energy and Electrification Laboratory, Department of Agricultural Technology, Faculty of Agriculture, Universitas Sriwijaya. The study comprised of three stages: DSSC structure preparation, assembly and arrangement of DSSC layers, and DSSC measurements. The thickness variations of the fiber tissue layers used were two layers (0,027 cm), three layers (0,041 cm), four layers (0,054 cm), five layers (0,068 cm), six layers (0,081 cm), and a control without fiber tissue layer applied to water hyacinth leaf dye and senduduk fruit dye. Parameters observed in this study included current and voltage characteristics, power calculations, fill factor, and DSSC efficiency. The results indicated that DSSCs with an additional fiber tissue layer exhibited relatively better performance compared to DSSCs without the additional fiber tissue layer, both in the senduduk fruit dye and water hyacinth dye.. The DSSC performance was most prominent in the senduduk fruit dye sample with a four-layer (0.054 cm) thickness of fiber tissue layer. The electrical characteristics produced by this sample were Isc:  0,016 mA, Voc:  0,682 mV, Imax:  0,011 mA, Vmax:  0,397 mV, Pmax:  0,00417 mW, FF:  0,37924, and an efficiency of 0,016%.

Herlin, W., Fatkha, F. N., Zagar, Z., Destia, H., & Yuniva, E. A. (2024). Optimization of Babadotan weed (Ageratum conyzoides) as a vegetable pesticide on cayenne pepper plants (Capsicum frutescens L.) . In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 195–201).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Chili pepper plants (Capsicum frutescens L.) have high potential for cultivation. The density of pests that attack cultivated plants causes the pest population to swell. This study aimed to determine the effectiveness of babadotan weeds as botanical pesticides on chili pepper plants. The method used in this study was a Randomized Block Design (RAK), using 5 treatments, namely P0 (control), P1 (50 g / L), P2 (100 g / L), P3 (150 g / L), P4 (200 g / L) consisting of 6 replications with a total of 30 plants. The results of this study showed the growth of chili plants that were given botanical pesticides from several treatments carried out, namely plants that were not treated or not given pesticides were attacked more than chili plants that were given a lot of pesticides. In terms of plant height, the growth of chili plants that were given more botanical pesticides was higher than plants that were given less pesticides, in terms of the number of leaves, chili plants that were given more botanical pesticides had more leaves than chili plants that received less treatment. The conclusion of this study shows that botanical pesticides from babadotan weeds act as insecticides, repellents, binders, and pest growth inhibitors. Thus, it is necessary to use insecticides in the right dosage to control pest attacks on cayenne pepper.

Maghzarini, N. S., Setyawan, D., & Hanum, H. (2024). Principal component analysis for micro environmental factor and angsana growth at FABA experimental plot in Banko Barat, Tanjung Enim. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 543–555).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Post-mining revegetation often uses highly adapted plant species to harsh conditions including those from legumes like Angsana (Pterocarpus indicus). Microenvironmental factors such as soil moisture, temperature, light, and soil pH affect plant growth. The research aimed to monitor the microenvironment and evaluate the response to plant growth on coal post-mine land. This research was conducted from October to November 2023 in the FABA (fly ash and bottom ash) IUP PIT 3 landfill in Banko Barat (Tanjung Enim). Field observation used a survey method.  A random sampling of 39 plants was selected from 65 seedlings using the Slovin formula. Micro-environment measurement includes soil moisture, temperature, pH, and flux intensity. Plants were measured for stem diameter and plant height. Data obtained were analyzed using PCA (Principal Component Analysis). Soil moisture varied greatly from 25.3 to 90.7 %. Soil temperature ranged between 30.8 and 42.4°C. Light intensity differed widely between morning and afternoon measurements (35000 and 135000 lux respectively). In general plant height and stem diameter increased slowly. PCA indicates that 52.69% of data variance is related to soil temperature and stem diameter. There is a great variance between plant samples attributed to environmental factors and plant growth.

Abstract

Maryani, S., Novriadhy, D., & Karenina, T. (2024). The effect of peat soil compaction on physical properties at the Sriwijaya Botanical Gardens, South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 878–885). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The physical characteristics of the soil at each location are always different, especially for land that contains peat. The Sriwijaya Botanical Gardens of South Sumatra is a botanical garden on peat land with five functions, namely plant conservation, research, education, tourism and environmental services. These various functions will result in soil compaction which also affects the physical properties of peat soil, so research is needed to determine the effect of peat land compaction on the physical properties of the soil at the Sriwijaya Botanical Gardens of South Sumatra for planning the management of this land in the future. This research was conducted at the Sriwijaya Botanical Gardens in Bakung Village, Indralaya Utara District, Ogan Ilir Regency, South Sumatra Province with a peat land type. Soil sampling was carried out using a soil sample ring at a soil depth of between 0-20 cm. The sample points were determined as many as 20 points on a land area of 100 hectares. The parameters of the physical characteristics of the soil observed were bulk density, soil pore space and water content. Observations of the physical characteristics of the soil were carried out at the Laboratory of the Soil Department, Sriwijaya University. The results of the study showed that the physical characteristics at several soil sampling locations in the peatlands of the Sriwijaya Botanical Gardens of South Sumatra varied, influenced by the function of the land before and after development, the depth of the peat, and the distance of the location from the canal. The physical characteristics of the soil bulk density value at the location ranged from 0.15 to 0.38; the soil pore space obtained with an average value of 93.68% and the saturated water content ranged from 66.68% - 98%). It is hoped that the identification of the physical characteristics of this land can be used as a reference material in the planning and management of peatlands at this location in the future.
