<![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 study aims to examine the influence of Servant Leadership, Self Awareness, Workload on Organizational Citizenship Behavior (OCB), and Employee Performance at Badan Perencanaan Pembanguna Daerah (BAPPEDA) Provinsi Jawa Timur. The research was conducted using a quantitative approach and data were collected from employees working at BAPPEDA Provinsi Jawa Timur. The collected data is analyzed using the Structural Equation Modeling (SEM) PLS method with the Smart PLS Version 4.0 software. The respondents for this study were 118 employees out of a total of 137 employees at BAPPEDA Provinsi Jawa Timur. The data collection instrument was measured using a Likert scale. The research findings indicate that Servant Leadership significantly influences OCB but does not significantly affect Employee Performance. On the other hand, Self Awareness significantly influences both OCB and Employee Performance, while Workload does not significantly affect OCB but has a significant impact on Employee Performance. Additionally, OCB significantly influences Employee Performance. These results highlight the importance of implementing Servant Leadership and fostering Self Awareness to encourage OCB, while Workload has a greater impact on employee performance. Interestingly, the implementation of servant leadership does not seem to drive employee performance at BAPPEDA Provinsi Jawa Timur, however the high level of OCB in BAPPEDA of East Java Province can enhance employee performance. Keywords: Servant Leadership, Self-Awareness, Workload, Organizational Citizenship Behavior, Employee Performance]]>

<![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[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.]]>

<![CDATA[In this article, the focus was on the analysis of the conflict and personality of Josephine March the main character in the movie "Little Women (2019)" by Greta Gerwig. This research data was in the form of scenes supported by the movie script. These data were determined based on the type of conflict according to Kenney's theory (1966), then the personality type faced by the main character was analyzed based on Freud's theory (1923). The results show that there were 98 conflict data. The actions of Josephine March in both internal and external conflict demonstrated the presence of the id, ego, and superego personality types. The Id represented her fundamental desires and urges, whereas the ego served to balance these desires within the bounds of reality. The superego was a representation of the social norms and ideals that shape her conduct. She also exhibited a blend of id-ego and ego-superego behaviors, highlighting the complexity of her character as she balanced her innate impulses with the needs of reality and external expectations.]]>
