Nur, R.D. (2023). The Influence of Climate on the Growth of Horticultural Commodities in Enrekang Regency, South Sulawesi. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 482-489). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Indonesia is a country with a variety of agricultural commodities. The agricultural sector, including horticultural commodities, plays an important role in contributing to Gross Regional Domestic Product in Indonesia. Enrekang Regency is one of the regencies in South Sulawesi which produces various kinds of horticulture, mainly onions, cabbage and tomatoes. The impact of climate change on the agricultural sector is multi-dimensional, both in terms of agricultural infrastructure, production systems and the welfare of farmers and society in general. One of the challenges faced in horticultural productivity is climate change which affects the amount of horticultural crop production. In this research, we will examine the percentage influence of climate on several types of horticultural plants such as tomatoes, petai, beans and chilies. This research uses horticultural production data obtained from the Enrekang and South Sulawesi District Agriculture Services using documentation methods for 11 years (2011-2021). Then, data on weather conditions was taken from the Meteorology, Climatology and Geophysics Agency for the last 11 years. These data are then processed with regression and correlation analysis using the SPSS application. The results of the regression analysis show that the overall influence of climate on 4 variables (Petai, Beans, Tomatoes, and Chilies) respectively is *R value =.492, R =.578, R =.465, and R =.514*. This shows that climate has a significant correlation and influence on the productivity of horticultural crops as much as 50% and then the remaining 50% is influenced by other variables outside the research. Therefore, it is necessary to carry out further studies regarding the factors that have an impact on the production of horticultural crops, such as land management and pest prevention.

Nirwani, L., Wahyudi, W., Suharyono, G., & Maulidia, M. (2023). Transfer factor 137cs from bengkayang soil to corn plants (Zea mays). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang, 21 Oktober 2023. (pp. 581-590). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This research aimed to obtain the transfer factor value of 137Cs from Bengkayang soil to corn plants. A pot experiment using a completely randomized design tested two treatments, namely soil that had been contaminated with 137Cs and without 137Cs (control). After harvest, the dry weight of the plants was measured and measurements were made using a Gamma Spectrometer of the concentration of 137Cs in dry plants and dry soil to obtain values. the transfer factors. The results of preliminary soil analysis obtained a soil pH of 6.4, this value is a good pH value for the growth of corn plants, namely 5.5 – 7. The organic matter content of the soil is classified as low to medium. The soil texture used in the experiment was sandy clay loam which consisted of 76% sand, 9% dust and 15% clay, a soil texture that was good enough for the growth of corn plants. The transfer factor value of 137Cs from Bengkayang soil to corn plants is between 0.6396 - 4.6336 with an average value of 2.0814, where the value obtained is higher when compared to data released by the IAEA (2010), namely the transfer factor from soil to corn plants is 0.0030 – 0.4900.

Safrina, D., Susanti, D., & Wijaya, N.R. (2023). Product development of parijoto fruit (Medinilla speciosa Blume) and its potential as a medicinal plant : review. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 43–53). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Parijoto (Medinilla speciosa Blume; heterotypic synonym of Medinilla eximia (Jack) Blume) is a shrub from the Melastomataceae family which is known as an ornamental plant and is not widely known as a medicinal plant. Parijoto fruit contains tannins, flavonoids, glycosides, saponins, and alkaloids. People traditionally use parijoto fruit to treat canker sores, diarrhea, anti-inflammatory, antibacterial, anticancer, male fertility, and antioxidants. Several research results state that the parijoto plant has medicinal plant potential as an anti-obesity, anti-hyperlipidemia, anticancer, antibacterial, antioxidant, increasing fertility, hepatoprotector, and immunomodulator. Parijoto fruit has enormous potential as a medicinal plant, but it has yet to be widely developed by the community. This review article aimed to inform the public about the enormous opportunities in developing research from cultivation to product formulation. Based on the review results, information was obtained that the development of processed products is still minimal, and most of it is still on a research scale. Parijoto fruit has the potential to be developed into food products, including syrup, dodol, and jelly candy. Parijoto fruit can also be developed as a cosmetic preparation, such as body lotion and sunscreen cream. Apart from that, this plant also has the potential to be developed as a food coloring. Products made from parijoto fruit still need to be improved and have yet to be utilized by the wider community, so the potential for developing parijoto fruit is still enormous.

Variety bima brebes with seven composisitions of sugarcane blotong and cow manure. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 214-222). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Bima brebes shallot variety is shallot variety that is widely cultivated by farmers because it is easy to grow, in recent years farmers have experienced a 50% decrease in yield due to decreased soil frtility due to chemical fertilisers, to overcome this the use of chayote blotong and cow manure can be used for shallots, this study aimed to determine the growth of shallots (Allium ascalonicum L.) bima brebes varieties with seven different compositions of sugar cane blotong and cow manure. The method used was the research method of Randomized Group Design (RGD) consisting of 7 treatments, with the composition (soil: sugar cane blotong: manure) namely P0 (2:0:0), P1 (2:2:0), F (2:2.5:0.5), P3 (2:1:1), P4 (2:0.5:1.5), p5 (2:0:2), and P6 (1:1:1) analysed by variance analysis (ANOVA). The results of applying mixed manure had an effect on shallot plant height, number of leaves, fresh weight and dry weight of stalks, fresh weight of beetles, dry weight of beetles, number of bulbs, diameter of bulbs and measurement of root length, but had no significant effect on the number of seeds and greenness of leaves. Mixture of soil: sugarcane blotong: cow manure with P2 (2:1.5:0.5) was the best treatment and P5 (2:0:2) was the slowest treatment. The conclusion of this study shows that the combination of sugarcane blotong and cow manure on shallots can increase growth and production. It is recommended that further research be carried out in the field in order to obtain a more appropriate dose of shallots.

Sidik, E.A., Laeshita, P. (2023). Association of begomoviruses and betasatellit in controlling yellow disease through a biotechnological approach. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 660-672). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Begomovirus belongs to the Geminivirus family, which is the largest genus that causes disease in many plants. Begomovirus genomes are monopartite and bipartite. In recent years it has been known that monopartite and bipartite begomoviruses associate with ssDNA satellit (betasatellit). Recombination that occurs between begomoviruses and betasatellit can trigger the emergence of new species and play a role in spread. The goal of this article is to describe the association between begomoviruses and betasatellit and their role in control using biotechnological approaches. This article was studied applying a scientific literature review process. This association plays a role in triggering the emergence of symptoms in the pathogenicity process. The betasatellit region contains a single open reading frame (ORFs) (βC1 gene) as a determinant of pathogenicity. Begomoviruses and betasatellit contain ORFs that encode replication, transcription, and RNA silencing (suppressing gene silencing) activities. The existence of this association can be an alternative control that utilizes the application of RNA interference (RNAi) to control begomovirus infection. Implemented by producing transgenic plants that harbor two different RNAi hairpin intron constructs using conserved regions from the viral genome and ORFs βC1 from the betasatellit genome. The multifunctional nature of the encoded protein may be a promising alternative in the development of resistance against begomovirus infection. In the end, transgenic plants were produced with milder symptoms and less viral DNA accumulation.

Hardi, E.H. (2023). Suboptimal land optimization for aquaculture: Indonesia's contribution to global food security. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 25-32). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).In Indonesia, the subtropical land is dominated by peat and mangroves, both of which have the potential to be used for aquaculture. The implementation of smart aquaculture, in which the management uses four concepts including natural activity, zero waste, circular activity, and sustainability. Optimizing the mangroves ecosystem as an area for filtration and sedimentation for aquaculture and waste air before it is discharged is an important part of maintaining ponds. The utilization of plant extracts as antibacterial, immunostimulants, prebiotics, and natural pesticide is the foundational tenet of smart silvofishery as opposed to the cultivation practice of using chemical fertilizers and pesticides. There are four advantages to smart silvofishery: mangrove litter supplies total nutrients (nitrogen, potassium, and phosphorus); increasing total plankton (8 phytoplankton species and 11 zooplankton species); suppressing pathogens in ponds; increasing the amino acid and fatty acid content of shrimp meat; and increasing pond production. Mangrove litter supplies total nutrients (nitrogen, potassium, and phosphorus). Aquaculture carried out in peat and mangrove environments is safe (for the environment, fish, and customers) when smart silvofishery is utilized. This results in increased productivity while also maintaining the safety of the products that are created.
