Fitra MJ, Utpalasari RL, Kurniawan R. 2020. Organoleptic characteristics of jelly candy from catfish bone gelatin (Ophioceplaus striatus) with the addition of okra slime. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The availability of raw material for gelatin from waste, especially fish bones in Palembang city is high enough. Therefore, gelatin that is processed from raw fish waste can be used as an alternative of halal gelatin besides gelatin derived from beef bones. Gelatin is widely used in industries, especially the food processing industry such as jelly candy. Candies are sweets, it was made by mixing a certain concentration of sugar into water and then adding flavor. Many people deliberately eat candy while doing various activities. Candy is considered as a snack that can help the mind become fresher so that it will certainly make us concentrate or thinking better. The high sugar content in candy products can often lead to problems caused by excessive sugar consumption. In this study, the researchers added okra mucus, which apart from being rich in vitamins and minerals, okra is also rich in fiber. However, the use of okra slime into food products, especially candy, is still limited because people don't like the mucus found in okra fruit. Futher more, researchers added okra slime to candy made from fish gelatin so that it could be accepted by the public. This research was conducted at the UPGRI Palembang THP Workshop and agricultural products laboratory, Faculty of Agriculture, Sriwijaya University. This study aimed to determine the level of preference for the panelists to jelly candy added with okra fruit mucus which includes PO1 was 0%, PO2 was 2.5%, PO3 was 5%, PO4 was 7.5% and 10%. The results of the organolpetic analysis data were analyzed by using the non-parametric Friedman Conover statistical test. The results showed that the addition of okra slime to jelly candy made of Gabus fish waste gelatin (Ophiocepalus striatus) had a significant effect on appearance, aroma and taste. The best treatment was the PO2 treatment (jelly candy from snakeheadfish waste gelatin with the addition 2.5% of okra slime) with a liking level of appearance was 3.50 (good), aroma was 3.03 (rather good) and taste was 3.73 (good ).Keywords : Gelatin, Okra Slime, Jelly Candy

Kusmiyati S, Setyowati N, Turmudi E. 2020. The dynamics of weed communities and land productivity in intercropping corn and green bean. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Intercropping increases the productivity of plants through land efficiency. The types of weeds grow in intercropping are different from that of monocultures. This study aims to identify the type and number of weeds on intercropping corn and green beans and describe the relationship between weed competition and the productivity of corns and green beans. The study was conducted in September 2018 until January 2019 at Pematang Gubernur, Bengkulu, using a Randomized Complete Block Design. Corn spacing in intercropping was 60 cm x 30 cm, 90 cm x 30 cm, and 120 cm x 30 cm as well as 60 cm x 30 cm in monoculture while green bean spacing was 30 cm x 30 cm. The main variable data were collected and analyzed using analysis of variance level 5%. The results showed that four weed species consisted of three broad-leaved weed species, and one grass species were identified before land cultivation. At three weeks after planting, weeds' composition was nineteen consisting of fourteen broadleaves weed, one sedge, and four grass. At nine weeks after planting, the composition of nine species of weeds consisted of seven broad leaves, one nutsedge, and one grass. The presence of weeds reduced the yield of corn and green beans in the intercropping system.

Paradisa YB, Perdani AY, Indrayani S. 2020. Resistance of Local Rice from Tabalong to Four Races of Blast disease. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).One of the suboptimal land uses is for upland rice cultivation. However, the challenge in developing upland rice is disease attack, especially blast disease caused by Pyricularia grisea (Cooke) Sacc. The precaution that can be taken to reduce yield losses due to this disease is using resistant cultivars. A number of local rice germplasm is known to be resistant and tolerant to biotic and abiotic stress. So that local rice has the potential to be candidate parent crosses. This study aims to determine the level of resistance of local rice as candidate parent crosses especially local rice collected from Tabalong, South Kalimantan. Resistance information can be used to create resistant cultivars. This research was using eleven local rice (Jalapkin, Siam Rambung, Tambak Wangi, Mu'uy, Siang Tipung, Tipung, Mayas, Siam Sumut, Siam Jambul, Cantik Manis, and Lampung Gajah Putih). Research was performed at 18 days old plant and the treatment was repeated 4 times. Cultivar Asahan was used as resistant control, while Kencana Bali as susceptible control. Based on the study result, it is known that all of the local Tabalong rice has the potential to be used as parent crosses to create plant resistance except for Jalapkin and Tambak Wangi. However, Siam Rambung, Mu'uy, Tipung, Siam Jambul, Cantik Manis and Lampung White Elephant were more potential because resistant to 4 blast races
