Abstract

Post-tin mining land has low nutrient content, which makes it harder for plants to absorb macro and micronutrients. Adaptive plants such as pakchong grass and the application of nitrogen fertilizer are solutions for cultivating and increasing post-tin mining land productivity. This research was conducted to identify the most efficient doses of nitrogen fertilization for pakchong grass in post-tin mining land. This research was conducted in Kampoeng Reklamasi Air Jangkang, Bangka Regency. This research used a randomized block design consisting of 4 treatments, i.e., A0 (without N fertilizer), A1 (6.125 g N/plant), A2 (7.875 g N/plant), and A3 (9.875 g N/plant). Data obtained were subjected to analysis of variance (ANOVA) followed by the Least Significant Difference (LSD) test at a 95% significance level. The results showed that the application of different doses of nitrogen fertilizer significantly affected the dry weight of the canopy and yield per plot. The treatment of A3 (9.875 g N/plant) had the highest yield but was not significantly different from the A1 treatment (6.125 g N/plant) and A2 treatment (7.875 g N/plant). The highest fat content was in the A2 treatment (7.875 g N/plant), and the highest total N and protein content was in the A treatment (6.125 g N/plant). The best nitrogen treatment in this research was A1 (6.125 g N/plant), which had lower nitrogen treatment but had similar results with the higher dose of other nitrogen fertilizer, making it more efficient for nitrogen fertilization in post-tin mining land.

Abstract

Parosphromenus deissneri is a freshwater species known exclusively from Bangka Island, Indonesia. According to the IUCN Red List of Threatened Species in 2020, this species is endangered, and the population continues to decrease due to the consequences of open-pit tin mining on Bangka Island harming its natural ecosystem. Despite the fact that this species is regarded as endangered, no known conservation and domestication initiatives have been made to enhance its number in the wild. In this study, we propose to do domestication of P. deissneri using biotope principles and techniques to increase the P. deissneri capacity for adaptation and reproduction since these species believe they are in their natural habitat. This study was carried out from April to September of 2023 at Bangka Belitung Endemic Fish Laboratory. We designed the biotope concept using an aquarium with dimensions 200 cm x 100 cm x 50cm. Biotopes are equipped with aquatic plants, roots, twigs, dead leaves, sand, rocks, gravel, and water containing natural plankton as biotic and abiotic elements. In this study, a Parosphromenus deissneri broodstock of 20 individuals (10 males and 10 females) was maintained for a 5-month period, resulting in an 80% survival rate. During the study, one mating pair successfully produced approximately 14 eggs, 8 of which hatched. Following a 2-month larval development phase, 4 fry survived to adulthood, yielding a survival rate of 25% relative to the total number of hatched eggs. These results underscore the necessity for refined husbandry practices and optimal environmental conditions to improve fry survival and enhance reproductive success in future breeding efforts.

Abstract

The importance of quality seeds that are adaptive in local rice production centers greatly determines plant productivity, especially for strategic food commodities that are really needed by the community. The successful application of superior rice seeds cannot be separated from the farmer's rationality regarding the use and usefulness of these superior seeds. This research aims to identify superior rice seeds used by farmers in production centers and analyze the comparative effect of using superior seeds on the welfare of farmers in South Bangka Regency and Bangka Regency. Data collection was carried out through a survey of 60 rice farmers in Toboali sub-district, South Bangka Regency and in West Mendo District, Bangka Regency. The research data was analyzed using descriptive analysis and propensity score matching to see the effect on farmer welfare. Based on the research results, it was concluded that the characteristics of the superior rice seeds used by farmers in the production centers of Bangka Regency and South Bangka Regency had different characteristics based on the specific location and type of rice produced. The use of superior rice seeds has the effect of increasing income, increasing productivity and increasing the selling price of rice which has significant differences between the two groups of rice farmers in Rias Village, Toboali District, Bangka Regency and rice farmers in Payabenua Village, Mendo Barat District, Bangka Regency.

Abstract

This study investigates the relationship between ethnic diversity and the management practices and productivity of lowland rice farming in South Bangka Regency. The region's multi-ethnic composition—comprising Malay, Javanese, Bugis, and other ethnic groups—offers a unique context to explore how cultural backgrounds influence agricultural decisions and outcomes. Using a mixed-methods approach involving field surveys, in-depth interviews, and productivity data analysis, the study identifies key differences in land preparation, input usage, labor organization, and post-harvest handling across ethnic groups. The findings reveal that ethnic-based variations in farming knowledge and social capital significantly affect productivity levels. The study concludes by recommending culturally tailored agricultural extension strategies to improve rice productivity in ethnically diverse communities.
