The research was carried out for 4 months, the research location was in Sidomulyo, Umaq Dian, Buluq Sen and Tukung Ritan Villages, Tabang sub-District, Kutai Kartanegara Regency. Research activities carried out include: preparation, field observations, soil sampling, soil sample preparation, soil analysis in the laboratory, data processing and interpretation, and reporting. The results showed that: (1) Land with not degradated status was found at four location i.e TB 2, TB 4, TB 10 and TB 11; (2) lightly degradated status occurred in 7 location i.e TB 1, TB 3, TB 5, TB 7, TB 8 dan TB 9; (3) land with moderate degradated status occurred at TB 6. Land degradation for biomass production mostly occurs in dryland caused by damage to the basic properties of the soil which includes soil pH, soil erosion, and bulk density. 2023-09-09T00:00:00Z http://repository.unmul.ac.id/handle/123456789/57024 Blood presence in trachea and length of death as animal welfare indicators in Tanah Merah slaughterhouse Suhardi, Suhardi 2023-06-06T00:00:00Z http://repository.unmul.ac.id/handle/123456789/57022 The effect of local feeding of Hymenachne amplexicaulis grass on the body condition score of Bali Cattle Suhardi, Suhardi 2023-06-07T00:00:00Z http://repository.unmul.ac.id/handle/123456789/55668 PROCEEDING INTERNATIONAL CONFERENCE TROPICAL AGRIFOOD, FEED AND FUEL Eliyani, Eliyani This research was conducted from May to September 2022 to assess the growth and yield of BC1F5 Pandan Ungu/Kambang//Pandan Ungu rice plants, determine the influence of environmental factors on the agronomic characteristics of BC1F5 Pandan Ungu/Kambang//Pandan Ungu rice lines through heritability analysis, and establish correlations between agronomic characteristics and the yield of the BC1F5 Pandan Ungu/Kambang//Pandan Ungu line. The research followed a randomized block design with three replications, using different strains as treatments. Data obtained were subjected to variance analysis (Fisher's test) at a 5% significance level. If a significant effect was observed, Duncan's Multiple Range Test (DMRT) was conducted at the 5% level. To assess the impact of environmental factors, heritability analysis (h2) was performed. Additionally, a correlation analysis was carried out using the Pearson product-moment correlation formula to understand the relationships between characters. The results of the research revealed variations in growth and yield among the 24 backcross lines of Purple Pandan/Kambang//Purple Pandan. Three characters exhibited high heritability values: plant height, panicle length, and the number of grains per panicle. Four characters showed moderate heritability values: harvest age, number of grains per hill, weight of 1000 grains, and weight of grain per hill. One character had a low heritability value: the number of offspring. Based on the four selection criteria, 12 lines were identified for further selection, specifically lines 17, 41, 55, 57, 117, 141, 149, 197, 296, 303, 375, and 389. Notably, the character of grain weight per hill had a significant and positive correlation with the number of tillers and the number of grains per hill, while the other characters did not significantly affect grain weight per hill 2023-09-19T00:00:00Z
