Tapioca industrial wastewater contains high concentrations of organic matter, suspended solids, and toxic compounds, necessitating the need for effective and sustainable treatment prior to discharge. This study evaluated the performance of bioflocculants produced by <i>Alcaligenes latus</i> in treating tapioca processing effluent, applied both independently and in combination with the chemical coagulant alum. Experiments were conducted at the bioindustry laboratory, faculty of agricultural technology, Bogor Agricultural University, using wastewater from <i>PT Inti Sumber Agung Lancar</i>, East Lampung. Bioflocculants were produced through fermentation and tested using the jar test method. Key parameters analyzed included total suspended solids (TSS), biological oxygen demand over 5 days (BOD₅), chemical oxygen demand (COD), color, cyanide content, and pH. The optimal combination of 2 mL bioflocculant and 6 mg alum achieved the highest removal efficiencies for COD (83.80%), TSS (70.15%), and BOD₅ (67.38%), with notable reductions in cyanide (31.29%) and color (15.98%), while maintaining neutral pH (6.85-6.94). The results demonstrate a synergistic effect between biological and inorganic coagulants, highlighting their potential as an eco-friendly alternative to synthetic agents. This approach contributes to achieving the goals of SDG 6, SDG 9, SDG 12, and SDG 14 by promoting cleaner industrial processes. Moreover, the study’s outcomes provide enrichment material for environmental biology education, fostering awareness of biotechnological innovations that support sustainable development.

People living with disabilities have the same rights as non-disabled individuals to access financial services. However, in 2023, as many as 75.7% of people living with disabilities in Indonesia still did not own a bank account, even though account ownership is the most fundamental element of financial inclusion. This study aims to analyze the association between financial inclusion on the welfare of people living with disabilities in Indonesia. This study employed cross-sectional data from the March 2023 National Socio-Economic Survey (Susenas) to analyze the association between financial inclusion on the welfare of people living with disabilities, focusing on household heads with disabilities as the unit of analysis, representing a weighted sample of 8,726,103 households. Welfare is proxied by the average household expenditure of the household head, which includes both food and non-food components such as health and education spending. The Propensity Score Matching (PSM) technique was applied using a probit-based model via Stata software. The assumptions of common support and standardized bias were verified and satisfied. Using three different financial inclusion index cut-off points—≥25%, ≥ 50%, and ≥ 75%—the results revealed that the Average Treatment Effect on the Treated (ATT) of financial inclusion positively and significantly associated with the welfare level of household heads with disabilities, ranging from 22.83% to 23.43%, 29.47%-29.87%, and 31.23%-33.23%, respectively. These findings indicated that higher levels of financial inclusion among household heads with disabilities were associated with higher levels of welfare attainment. The findings suggest that financial inclusion programs play a crucial role in enhancing the welfare of people living with disabilities, as they have a positive and significant association on improving their well-being.

This study investigates the influence of school principals’ leadership, grounded in the Javanese philosophy of Ing Ngarso Sung Tulodo, which, in English, at the front gives an example, and the school climate on the professional competence of elementary school teachers in Indonesia. The Ing Ngarso Sung Tulodo philosophy emphasizes the role of leaders as role models who inspire and guide their subordinates. A positive and supportive school climate is likewise considered essential for fostering teacher development. Adopting a quantitative research design, this study involved 122 elementary school teachers selected through cluster sampling in Lampung Province, Indonesia. Data were collected using a structured questionnaire and analyzed using Structural Equation Modeling (SEM) with SmartPLS 3.0. The results of the study indicate that leadership grounded in Ing Ngarso Sung Tulodo and a conducive school climate have a positive, statistically significant effect on improving teacher competency (p < 0.001). This result differs from most studies of educational leadership at the global level, which still focus on the dominance of Western leadership models and rarely integrate local cultural values as the primary basis for analysis. This study explicitly fills this gap by presenting a leadership model rooted in local wisdom. This study provides a new space for empirical testing of culture-based leadership to improve teacher competency. This area has so far been under-researched in the international literature. Theoretically, this study enriches the study of educational leadership by broadening the perspective of leadership models through the integration of non-Western cultural values. Practically and internationally, this study can provide important implications for policymakers and school administrators, especially in multicultural and developing countries, in designing leadership development programs and school governance that are contextual, globally relevant, and sensitive to local culture.

Abstract Glioblastoma Multiforme (GBM) is one of the most malignant forms of brain tumor in humans, with limited treatment options and poor overall survival rates. In the present study, we employed an in-silico workflow that integrated immunoinformatics and 3D structural modelling tools to design a multi-epitope vaccine against Podoplanin (PDPN), a transmembrane glycoprotein primarily involved in tumor invasion and metastasis. The differential expression of PDPN in tumor versus normal cells was investigated using transcriptomics datasets. Once the overexpression was confirmed, it was designated as a Tumor-Associated Antigen (TAA). B-cell, CTL, and HTL epitopes were predicted and screened for antigenicity, non-allergenicity, and non-toxicity. Selected epitopes were linked with appropriate adjuvant and linker sequences to construct a vaccine candidate. Codon optimization and in silico cloning was conducted to evaluate the construct’s expression in a mammalian expression vector. The 3D structure of the vaccine candidate was modelled, refined, and validated before molecular docking with immune receptors and immune simulation studies. The results indicated that proposed polypeptide, RasIC -01v, could be a potential vaccine candidate for highly vigorous and dangerous cancer like GBM. Further experimental and immunological validations would be required to validate the commercial feasibility and development of RasIC -01v. Graphical Abstract

This research uses a field research method with a legal and descriptive-analytical approach, with primary data obtained from interviews and secondary data from legal documents and legislation. The summoning of parties in cases at the Religious Court is an important process in the settlement of cases, including absent cases such as divorce with parties whose whereabouts are unknown. In this context, the application of e-summon technology (electronic summoning) is expected to increase the effectiveness of summoning. This study aims to evaluate the effectiveness of the application of e-summons in absentia cases in the Tulang Bawang Religious Court using Campbell's (1970) theory of effectiveness, which includes four indicators: time efficiency, cost efficiency, accuracy of targets, and quality of service outcomes. This study uses a field research method with a juridical and descriptive-analytical approach, with primary data derived from interviews and secondary data from legal documents and legislation. The research results show that e-summons via website is more efficient in terms of time and cost compared to conventional methods, although there are still constraints on access to information by the defendant, which impacts the full realization of procedural justice.

Recitation of the Qur'an in Islamic boarding school education isn’t only understood as a ritual worship, but also as a religious practice that plays a big role in regulating emotions and fostering inner calm. In the daily life of students at Darul Muttaqin Islamic Boarding School, various pressures such as academic demands, memorization targets, homesickness, and social adjustment often generate psychological tension. This study explores how Qur’anic recitation functions as a form of psycho-spiritual therapy that supports students’ mental well-being. This study employed a qualitative descriptive approach with a field-based design. Information was obtained through in-depth interviews, participant observation, and documentation with fifteen students who regularly perform tilawah (Islamic recitation) and two female teachers. Data were analyzed using the Miles and Huberman model, which includes data reduction, data presentation, and conclusion drawing. The findings prove that tilawah assists students in managing their emotions, reducing anxiety, and cultivating spiritual tranquility. Students who consistently recite the Qur’an appear better equipped to cope with academic pressure and demonstrate patience, gratitude, and sincerity in their daily activities. These values serve as internal coping mechanisms that strengthen their psychological resilience. Overall, the study affirms that Qur’anic recitation can serve as an effective psycho-spiritual therapeutic model for maintaining students’ mental health in the pesantren environment.

Pyrolysis is a process of heating materials at high temperatures with little or no oxygen to chemically break down materials, to produce products such as fuel and liquid smoke. The purpose of this study was to determine the process, quantity, and characteristics of the products obtained from plastik waste and biomass. This research method uses a barner fueled by LPG gas. Using raw materials of LDPE plastik waste and biomass (rice husk) with a weight of 1.5 kg each. Using a batch type pyrolysis reactor and a straight pipe condenser with a diameter of 1 inch and a length of 4 m. The results showed that the two raw materials produced significantly different product proportions. LDPE pyrolysis produced a liquid product with a volume of 419 (mL) and a solid of 0.825 (kg), and had a higher calorific value of 10648.21 (kJ/kg) than rice husk. Meanwhile, rice husk pyrolysis produced a larger liquid (742 mL) with 0.316 kg of lower solids and a lower calorific value (8761.33 kJ/kg). This difference confirms that the type of feedstock significantly determines the quality and quantity of bio-oil or pyrolysis oil produced, which is crucial for renewable energy development and waste management.
