Sinaga AM, Sihombing EE, Raihan M, Prima MW, Nurlaila N, Sagita S. 2022. How to control in citrus limon plants performed by farmers in Tanjung Pering, Ogan Ilir, South Sumatera. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 318-326. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Oranges are the fruit of the annual plant of various citrus species in the family Rutaceae. Citrus plants, of course, have problems with growth, one of which is disease. The purpose of the survey is to find out what symptoms and diseases exist in citrus plants and find out how farmers control plants that are attacked by diseases in Tanjung Pering, North Indralaya District, Ogan Ilir Regency, South Sumatra. The research was conducted using a field survey method directly by collecting photos of citrus plants that were attacked by the disease, conducting interviews with farmers directly. Synthetic control is a way of controlling disease by citrus farmers in Tanjung Pering. Spraying by farmers is not done on a scheduled basis. Pesticide spraying activities are only carried out when many diseases and pests threaten agricultural activities. In controlling disease in citrus plants, biological and chemical control are carried out. Disease control in citrus plants should be done by means of biological control.

Sujinah, Diniaty R. 2022. Oxydative barrier of rice roots against iron toxicity. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 495-503. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Most of the mineral soils in swamps contain iron and under anaerobic and low pH, Fe3+ is reduced to Fe2+ which is easily soluble and absorbed by roots. Excessive of Fe2+ cause toxicity plants which will interference various plant metabolism. Iron is absorbed by roots into the root tissue, then transported through the xylem to the shoots. Precipitation of Fe2+ in plant tissues causes excessive production of reactive oxygen species (ROS), especially hydroxyl radical (OH-) through Fenton reacion, thereby damaging cell structures, membranes, DNA, and protein in plants. This paper will discuss how plant can avoid excess iron in the root area. The root tip is the first part that will get iron toxicity. At the tip of the root (root cap) produces cells called root border cells (RBCs) which play a role in protecting the roots from abiotic stress. In flooded conditions, there is a release of oxygen into the rhizosphere by aerenchyma, or called radial oxygen loss (ROL) which will induce the formation of iron plaque. The formation of iron plaque will the interfere with the absorption of root nutritions. One of the tolerance mechanisms that occur at the root level is the exclusion evasion through the ROL barrier and the entry of iron by forming lignin in the root cell wall.

Dewi IK, Mashendra K, Putri S, Maulindra Y. 2022. Lithology identification of peatlands by applying the ground penetrating radar (GPR) method in Jati Mulyo Village. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 166-177. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).There is an infrastructure development on peatlands in Jati Mulyo Village, Dendang District, Tanjung Jabung Timur Regency, so that lithological information is needed below the land surface. For this reason, it is necessary to conduct research with the aim of identifying subsurface using the Ground Penetrating Radar (GPR) method. The Ground Penetrating Radar (GPR) method is one of the geophysical methods that applied propagation of electromagnetic wave. GPR measurements were carried out as many as 3 passes with a track length of 200 meters on peatlands. The result of the response from GPR is in the form of colors that indicate subsurface lithology, The color distribution of the GPR response starts from yellow-red, green, light blue-dark blue colors. Based on the results of GPR measurements on peatlands, a yellow-orange response was obtained which indicates the presence of minerals contained in peatlands. The response of the green color below the surface is dominated by the soil. The response of the blue color indicates the presence of a cavity that is likely to be filled with water in it. From the results of GPR measurements on peatlands, it shows the presence of mineral content near the surface which indicates the mineral content on peatlands. The green color predominates beneath the surface which are sedimentary deposits derived from the Quarter Alluvium (QA) formation including peat soils. The presence of water underground shows that sedimentary deposits, especially peat soils, have large pores that can hold large amounts of water.

Maskuri M, Cahyani C, Wulandari DM, Sulista M, Wibowo JA, Faras MI, Wahyudi S. 2022. Identification of plant cultivation (Brassica rapa L.) hydroponics engineering film nutrient system (NFT). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 274-282. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The pakcoy is one of the many horticultural plants of interest in the banyudistrict, but the availability of the land is not what is needed to cultivate. This survey is aimed at seeing how plant labor USES NFT's hydroponics system and analyzing the yield. The method used was interviews from direct observation to farmers. Using the NFT hydroponic system is one of the hydroponic methods with a minimal flow of water and a tilted slant on the installation module. Also, by using hydroponic farming systems, you can maximize narrow-to-yield yield. As for the results of plant cultivation with NFT's hydroponics system, one of which is the plant plants that grow faster. Moreover, the output of this system is larger than the size of the plant plants. From the standpoint of rooting control, it is also easier to reduce the risk of rooting down. Then maintenance is also more practical and requires less energy. Therefore, the average use of NFT's hydroponics system would be greater in maintenance, control, and plant production. Removing moss from a maximum hydroponic installation two times over a harvest would reduce the development of the moss in a paralytic pipet.

Sutarma FA, Rhomadon AG, Asrul MR, Fitriyani D, Rahma FA, Anggraini HL, Umayah A, Gunawan B, Arsi A. 2022. Inventory and identification of ladybug (coleoptera: coccinellidae) on solanaceae crops in Ogan Ilir Regency, South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 450-457. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The ladybug (Coleoptera: Coccinellidae) is considered to have an influence on the cultivation of solanaceae crops because there are many types as biological control agents for plant pests and as phytophagous insects. The purpose of this study was to determine the types of ladybugs on Solanacae crops in Ogan Ilir Regency, South Sumatra, Indonesia. The sampling method used 2 techniques with insect nets swinging infinity on the plant canopy and direct collection techniques, namely taking directly by hand. Sampling of the ladybug in the field was carried out 3 times in each field. Sampling of the ladybug was carried out in the morning at around 07.00-10.00 am. Based on the results of sampling in the field, the beetles found were Coccinella sexmaculata, Verania discolor, V. lineata, C. repanda, and Epilachna admirabilis. This ladybug has different morphological characteristics, body size, and distribution between predatory ladybugs and phytophagous ladybugs. The species of ladybug that acts as a natural enemy is most commonly found in chili plantations. The predatory ladybug can control the attack of A. gossypii on eggplant and chili plantations. Coccinellidae phytophagous is a plant-eating ladybug that is commonly found in eggplant plantations. The conclusion in this observation is that there are 5 species of ladybug, 4 predatory ladybugs and 1 phytophagous ladybug. Research related to the identification and inventory of the ladybug (Coleoptera: Coccinellidae) needs to be improved as information on the types of ladybug species is useful in the management of solanaceae cultivation in order to further increase solanaceae crop yields in Ogan Ilir Regency.

Santoso A, Bustommi A, Setiawan IT, Rahayu RI, Miranda RD, Sembiring RS, Umayah A, Gunawan B, Arsi A. 2022. Population of fruit flies besides using methyl eugenol on chili plants in Ogan Ilir Regency, South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 120-128. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The attack of fruit flies (Bactrocera spp.) on red chili plants is one of the important problems in the red chili production process. In general, farmers still choose to use synthetic pesticides in controlling fruit flies. However, this control method has a negative impact, namely it can cause resistance and resurgence of the target pest. This review aimed to provide information about the benefits of compounds through bioattractants combined through the application of attractant traps in controlling fruit flies. This writing method uses a literature study which is analyzed and developed into an easy-to-understand review. Extraction contains methyl eugenol reaching 70-96%. The liquid compound methyl eugenol can be an attraction for male fruit flies. The trap attractant system has the ability to stimulate the interest of fruit flies and can be used for a long time. The application of trap attractants causes sexual communication disorders so that mating disorders occur in fruit flies. The conclusion obtained from the writing of this scientific paper is that the methyl eugenol compound in chili plants can be used as a control system.

Ahmy NUP, Santoso B, Wijaya A, Priyanto G. 2022. Addition of cream and palm sugar in fermented coffee formulation with different roasted levels. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 388-402. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Coffee with the addition of gambier makes the functional value of coffee drinks increase, but so that the taste of this functional drink is accepted by the community, in this study the addition of cream and palm sugar. The purpose of this study was to determine the effect of the type of fermented coffee and the degree of roasting on the improvement of chemical, functional and sensory properties. This research will be carried out at the Chemical, Processing and Sensory Laboratory of Agricultural Products, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University. This study used a completely randomized non-factorial design (RALNF) with 6 formulations. The results of this study indicate that the higher the coffee roasting rate, the lower the antioxidant activity and total phenol. This is a result of heating which can accelerate the oxidation of antioxidants contained in a material including phenolic compounds. The results of the analysis also show that the higher the roasting rate, the higher the average pH value of instant coffee. This decrease in acidity value is due to the evaporation of some acids (chlorogenic acid and carboxylic acid) when the coffee is roasted. Based on sensory results that panelists tend to like the taste of coffee with a higher roasted level and a higher concentration of palm sugar. The type of fermented coffee formulation, roasted coffee level and the addition of cream and palm sugar had a significant effect on water content, antioxidant activity, total phenol, pH of the solution.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 78-87. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Maize is a strategic food commodity after rice, however national maize production is still low. This study aimed to determine the effect of the dose of bioameliorant on increasing soil fertility and maize growth in suboptimal land. The research method uses experimental methods with field experiments. The experimental design used was a randomized block design consisting of six bioameliorant dosage treatments, namely D0: control (without bioameliorant), D1: bioameliorant dose 5 tons/ha, D2: bioameliorant dose 10 tons/ha, D3: bioameliorant dose 15 tons/ha, D4: dose of bioameliorant 20 tons/ha, and D5: dose of bioameliorant 25 tons/ha. The results showed that the dose of bioameliorant treatment of 25 tons/ha could increase soil fertility as indicated by increasing concentrations of total N and available soil P and increasing plant N and P uptake, number of mycorrhizal spores, percentage of root colonization and plant growth. Of the six treatments of bioameliorant dose, the effect of the 25 ton/ha bioameliorant dose treatment was the best in increasing soil fertility and plant growth.

Nunilahwati H, Marlina N, Purwanti Y, Nisfuriah L, Aryani I, Rosmiah R, Zulfakar Z. 2022. Effect of dose of biofertilizer on growth and production of caisim (Brassica juncea L.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 226-233. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Biofertilizer are live microorganisms that are mixed into the soil as inoculants to help provide certain nutrients for plants. This study aimed to determine the effect of biofertilizer doses on the growth of mustard greens (Brassica juncea L.). The study was carried out in Seberang Ulu II District, Palembang City, South Sumatra from February to May 2021. The method used was a Non-Factorial Randomized Block Design (RAK) with 6 (six) treatments and 4 (four) replications with treatment H0 = 0 kg/ha, H1 = 20 kg/ha (0.05 g/polybag), H2 = 40 kg/h (0.10 g/polybag), H3 = 60 kg/ha (0.15 g/polybag), H4 = 80 kg/ha (0.20 g/polybag) and H5 = 100 kg/ha (0.25 g/polybag). The results of the diversity analysis showed that the effect of the dose of biofertilizer applied to caisim on plant height (cm), top root weight (g), and bottom root weight (g) had a significant effect, while plant height (cm) and leaf width (cm) had a very significant effect. The application of biofertilizer of 20, 40, 60 kg/ha, and 100 kg/ha on caisim plants showed lower growth and production than the application of 80 kg/ha of biofertilizer. The dose of biofertilizer 80 kg/ha is the best treatment for the growth and production of caisin mustard plants weighing 56.75 g/polybag.
