Analisis Produksi Serasah Mangrove pada Hutan Mangrove Desa Kurau Timur, Kabupaten Bangka Tengah, Bangka Belitung

Mangrove forests have many ecological functions such as retaining and trapping sediments, dampening waves, providing protection for fish and other biota, and assimilating nutrients. Most of the nutrients returned to the forest floor are in the form of litter. Litter has an important role for the soil and the microorganisms in it. This study aims to measure the productivity of mangrove litter in the mangrove forest of Kurau Timur Village, Central Bangka Regency, Bangka Belitung. The method used to measure litter production is litter storage using a 1m x 1m litter trap with litter collection every 7 days for 3 months. Environmental parameter data analysis was performed by PCA (Principal Component Analysis). The rate of litter production in the mangrove forest of East Kurau Village is with a dry weight of 2.72 gr/m2/day. The components that make up litter are grouped into 3 components, namely leaves (66%), stems (18%), and flowers/fruits (16%). The litter layer on the mangrove forest floor of Kurau Timur Village is with an average dry weight of 69.02 grams, a water content of 40.73%, and an estimated average biomass of 3.08 tons/ha.

The Effectiveness of Giving Information on Fe Drugs on Compliance and the Effectiveness of Adding Hemoglobin to Young Women in Central Bangka Regency

Adolescent girls experience an increased need for iron due to accelerated growth (growth spurt) and menstruation. In addition, young women are usually very concerned about body shape, so many eat inadequate food. As a result, young women are more prone to health problems, including anemia. Women of childbearing age tend to suffer from anemia because women experience menstrual cycles every month. Iron deficiency can reduce endurance so it can cause decreased productivity. Iron intake can be obtained through foods sourced from animal protein such as liver, fish, and meat. However, because not all people can reach these foods, additional iron intake is needed from iron tablets (TTD).
 This research is an observational type using a survey method with a cross-sectional design for young women at the Nurul Falah Air Mesu Islamic Boarding School in March - October 2021. The pre-and post-test stages were carried out before and after being given PIO Fen using 2 treatment and control groups. Samples were taken from as many as 44 young women.
 The results showed that the pre-test scores were lower in the treatment group than the post-test scores. From the analysis of the paired t-test, it was obtained that the value of p = 0.024 where the value (p <0.05), then Ho was rejected, meaning that there was an average difference in giving PIO to adherence to consuming Fe tablets. Whereas in the control group, it is known that the t count is -0.227, indicating that the pretest value is smaller than the posttest value. From the analysis of the paired t-test, it was obtained that the value of p = 0.747 where the value (p> 0.05), then Ho is accepted, meaning that there is no difference in the average without giving PIO.
 This study concluded that there was an average difference in giving PIO Fe to adherence, whereas without giving PIO, there was no difference, and there was a significant average difference in providing information on Fe drugs between those who were given PIO and not given PIO in female adolescents.

Assessing consumer empowerment and influencing factors in Central Bangka Regency: a multidimensional approach

The rapid development of trade technology in Indonesia exposes consumers to potential exploitation during purchasing. This study examines consumer empowerment in Central Bangka Regency using primary data from 88 respondents across four districts. The Consumer Empowerment Index (CEI) value of 38.53, classified as "understand," indicates a fundamental grasp of rights and obligations and reveals room for growth in consumer empowerment. The analysis shows higher empowerment during the purchase phase, with informed decision-making and support for local businesses. However, a weakness emerges in the post-purchase phase, as consumers are less likely to voice experiences or criticize unsatisfactory products, potentially impacting product quality and customer satisfaction. Regression analysis reveals that only years of schooling and age significantly influence the CEI, while the location of residence, gender, and income group do not have significant effects. The model's low R-squared value suggests potential refinement through additional variables or research. These findings provide valuable insights for the government and stakeholders to enhance Central Bangka Regency's consumer empowerment. Focusing on increasing consumer awareness and engagement in the post-purchase phase through targeted educational campaigns, consumer rights workshops, and accessible complaint channels is essential. However, it is crucial to recognize that observed associations do not imply causation and further research is required to establish causal relationships and explore other factors contributing to consumer empowerment.
