<![CDATA[The Social Health Security Program (SHSP) is a social protection program of the Government of Nepal that aims to enable all citizens to access quality and effective healthcare services without any financial burden. A cross-sectional household-based and quantitative in-nature study was conducted in Rasuwa district. This study's population was residents of Uttargaya rural municipality wards no 4 and 5. How different factors are related to SHI enrolment. Ethnicity (p=<0.001), religion (p=<0.001), IWI grade (p=0.010), know about health insurance (p=<0.001), the behavior of service providers (p=<0.001), neighbors enrollment (p=<0.001), discussed SHI with neighbors (p=0.001), and family members agreed to enroll (p=0.002) were significantly associated with enrollment in SHI whereas others factors did not show any significant association with enrollment in social health insurance. This study found that enrollment was significantly associated with different independent variables. Poor knowledge of SHI, unfriendly behaviors of service providers, lack of trust, and unaffordability of premium costs were identified as barriers. Furthermore, Inappropriate timing of premium collection, limited services point, feeling that enrollment was not necessary, long queue, inadequate number of enrollment assistant and mandatory refer card were also reasons for not enrolling in SHI.]]>

<![CDATA[This research is quantitative research with a descriptive approach. The population in this study were all people who received services at the Peace Village Office during the last two months. The sampling technique in this research is by using saturated samples. So the population in this study is the same as the sample size, namely 77 people. Data analysis uses multiple regression analysis to hypothesize the one day service model on community satisfaction. The results of multiple linear analysis show that the one day service model has a positive effect on the level of community satisfaction. The results of the research show that the implementation of the one day service model, in this case the one day service at the Peace Village Office, has gone well. Likewise with the level of community satisfaction with public services, where the people of Peace Village feel satisfied with the public services they receive.]]>

<![CDATA[This study explores the viability of utilizing biochar and hydrochar derived from pineapple waste as adsorbents for removing lead (Pb) from water. Pineapple residues, including stems, leaves, and fruit, were subjected to pyrolysis and Hydrothermal Treatment to produce biochar (PWB) and hydrochar (PWH) respectively. Fourier Transform Infrared (FT-IR) analysis was employed to characterize the surface properties of PWB and PWH, validating their potential as adsorbents. A series of adsorption experiments assessed the impact of pH (ranging from 2 to 6), contact time (ranging from 15 to 90 minutes), and temperature (ranging from 30 to 90°C) on the adsorption efficiency of both materials. Results indicate PWH to be markedly more effective, with an average Pb removal efficiency of 84.07% compared to PWB's 55.68%. The optimal contact time was determined to be 60 minutes for both materials. Moreover, pH 4.0 was identified as the optimal condition for Pb adsorption, showcasing a significant increase in biosorption capacity within this pH range. Additionally, higher temperatures corresponded to enhanced Pb2+ removal efficiency, rising from 75.02% to 87.58% as temperature increased from 30°C to 90°C. Overall, these findings underscore the potential of pineapple waste-derived biochar and hydrochar as promising, environmentally friendly adsorbents for addressing heavy metal contamination in water, particularly in wastewater treatment applications.]]>

<![CDATA[Vietnam’s renewable energy sector has witnessed notable advancements in recent years, particularly in wind and solar power generation. However, challenges persist, hindering the sector’s full potential. This study evaluates the current status of renewable energy development in Vietnam from 2015 to the present, identifying existing obstacles and proposing effective solutions. Achievements in harnessing wind, solar, biomass, hydropower, and waste-to-energy sources are highlighted. Challenges such as inadequate grid infrastructure, high initial investment costs, complex administrative procedures, and energy losses are addressed. The paper proposes a comprehensive set of solutions, including infrastructure upgrades, financial incentives, institutional reforms, technology transfers, and research promotion. Implementing these solutions synchronously holds the promise of accelerating Vietnam’s renewable energy development, contributing significantly to sustainable development goals. The findings provide insights for policymakers and stakeholders to enhance the efficiency of green energy deployment in Vietnam.]]>

<![CDATA[In Cambodia, para rubber sawdust is commonly used to cultivate oyster mushrooms due to its availability as a byproduct from wood factories, but country's significant cultivated cashew could be an alternative substrate. Hence, exploring new substrates becomes essential for farmers when there's a scarcity or price hike in para rubber. This study is in purpose of investigation the impact of para rubber vs. cashew sawdust and different mixture formulas on the growths and yields of Pleurotus ostreatus. The experiment was conduct in Factorial in CRD with two main factors: A) two different saw dusts which were para rubber sawdust and cashew sawdust and factor (B) was mushroom mixture formulas (B1 – B6). B4 of cashew sawdust displayed the highest efficiency at 32.24%, while B3 and B4 of para rubber sawdust showed efficiencies of 23.57% and 23.54%, respectively. In conclusion, based on this experiment, cashew proves more effective than para rubber for Pleurotus ostreatus production. Specifically, B4, consisting of 100kg of cashew sawdust, 8kg of rice bran, 1kg of calcium carbonate, 1kg of palm sugar, 1kg of sticky rice flour, and 0.2kg of magnesium sulfate, maximizes yields for P. ostreatus cultivation.]]>
