Tanjung, A. L., Dwi, N. M., Salsabila, A., Gultom, D. S., Ryzanta, A., Harun, M. U . (2024). Identification and comparison of quality of cucumbers (Cucumis sativus L) of the hercules variety from various districts in South Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 937–945).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This research was carried out in August 2024. Cucumbers have distinctive shapes and characteristics ranging from color, size and taste so that there is a comparison of each region that cultivates cucumber plants. The aimed of this research was to determine the morphology and quality of cucumber fruit from various districts in South Sumatra, and also get information about the diversity of quality of cucumbers from various districts (Lahat, Muara Enim, Oku, Musi Rawas, Pagar Alam). This research method uses a sampling technique by randomly buying cucumbers from collecting traders. All five samples were prepared from various districts.  All sampling cucumbers were analyzed at the Plant Physiology Laboratory, Unsri.  The variables observed were volume, length, brightness of skin color, and quality grade of cucumber.  All observed variables are analyzed non-statistically and compared with each other. Based on the results of diversity analysis of research data, the identification and comparison of the quality of cucumbers from various regions in South Sumatra gave rise to different assessments in each region. These differences show that cucumbers from Lahat have an average fruit length (23.7cm), and volume ( 32ml) as well as fruit grade A, and larger. Meanwhile, Muara Enim district has an average fruit length (23.2cm), and volume (87ml) and grade A. Oku district has an average fruit length (15cm), and volume (53ml) and grade C. Pagar Alam district has average fruit length (19.8cm), and volume (47ml), there is no grade, the Musi Rawas area has an average fruit length (18.5cm), and volume (64ml). This research shows that each region has different quality of cucumbers from each region which is caused by several factors including treatment and care for cucumbers, soil structure. As for suggestions from research.

Abstract

Agustin, A., Pratiwi, M., Aritonang, A. G. A., & Harun, U. M. (2025). Potential of Wild Plants as Biopharmaca Crops of Cocoa Plantations in Dray Land. 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).Cocoa plantations form microhabitats that benefit various species of wild plants in their agroecosystems. The cocoa plantation in Bamasco Village, Musi Rawas Regency, has a biodiversity of wild plants, including weeds. The weeds found there have the potential to be used as raw materials for medicine. To identify the types and availability of medicinal plants (biopharmaceuticals), research was conducted from July to August 2025. The research was carried out in stages, namely a survey of weed types in cocoa plantations, with coordinates 3.09079546S 103.0748104 E. Screening of the phytopharmaceutical potential of weeds was carried out, followed by screening of specific phytopharmaceuticals. Based on the survey, it was found that there were 36 species of weeds in the area, and 20 species had the potential to be used as biopharmaceutical plants. The phytopharmaceutical group originated from broad leaves (Ageratum conyzoides, Rauvolfa serpentina, Caryota mitis, and Psychotria virdiflora) and narrow leaves (Asystasia gangetica and Phylanlantus urinaria L.). Based on the families found, these include Asteraceae, Melastomaceae, Acanthaceae, Amaranthacea, Arecaceae, Rubiaceae, Solanaceae, Polypodiaceae, Combretaceae, Lauraceae, Ericaceae, Phyllanthacea, Vitaceae, and Apocynaceae. The dominant biopharmaca compounds found there are Senggani (Melastoma Candidum) and Senduduk (Melastoma Malabathricum). Furthermore, the biopharmaca found include Melastoma Candidum, Phyllantus urinaria L., Ageratum conyzoides, and Chromolaena odorata L., which serve as alternative treatments for chronic diseases such as anti-cytotoxic cancer cells, kidney failure, antidiabetes, and antihypertension.

Abstract

Ogandy, B. Z., Marlina, M., Harun, M. U., Kurnianingsih, A. (2024). Scarification of sengon (Falcataria moluccana) seeds using hot and cold water soaking combination application on sand planting media. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 623–633).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Scarification is a process done to break the dormancy and accelerate the process of water absorption in seed germination. The purpose of the study was to determine the most effective hot and cold water scarification methods on Sengon (Paraserianthes moluccana.) seed germination. In this experiment, a completely randomized design was used, with six treatments of soaking Sengon seeds in hot and cold water, with four replications, there were 24 units, with 20 seeds per unit.The total number of seeds was 480. Seed soaking, consisting of : soaked in 60℃ hot water for four minutes and then soaked in cold water for 12 hours (P1), soaked in 60℃ hot water for five minutes and then soaked in cold water for 12 hours (P2), soaked in 80℃ hot water for four minutes and then soaked in cold water for 12 hours (P3), soaked in 80℃ hot water for five minutes after that soaked in cold water for 12 hours (P4), soaked in 100℃ hot water for four minutes after that soaked in cold water for 12 hours (P5), soaked in 100℃ hot water for five minutes after that soaked in cold water for 12 hours (P6). The results showed that the dry weight of sprouts in soaking Sengon seeds in 100°C hot water for five minutes after that soaked in cold water for 12 hours was significant in sprout dry weight.
