Adequate access to clean water is a crucial necessity, especially for students(mahasantri) residing at Ma’had al-Jami’ah, a Technical Implementation Unit(UPT) under UIN Raden Intan Lampung. The increasing number of residents,uncertainty in water availability, and limited water sources pose significantchallenges in fulfilling clean water needs optimally. Therefore, a quantitativeanalysis of clean water demand is essential to determine the daily supplyrequirements. This study aims to calculate the daily water needs and forecastfuture demands as a basis for more efficient planning. The research employs theExponential Smoothing method using R software. To assess forecasting accuracy,the indicators used include Mean Absolute Percentage Error (MAPE), MeanAbsolute Error (MAE), and Mean Squared Error (MSE). The findings indicate thatthe clean water requirement that must be fulfilled is approximately 0.5079liters/second/day. The forecasting error values obtained are MAPE at 28.9%, MSEat 0.01568777, and MAE at 3.893837, which indicate an acceptable level ofaccuracy. In conclusion, the need for clean water is directly proportional to thenumber of mahasantri residing in the facility. Therefore, the provision of cleanwater should be aligned with actual demand data to ensure a more organized andefficient distribution. This approach supports sustainable water management andcontributes to the overall comfort and health of the dormitory environment.

Higher Order Thinking Skills (HOTS) are high-level thinking skills that include analytical, evaluative, and creative abilities. HOTS is essential in 21st-century education, where students are expected not only to recall information but also to think critically and creatively in facing various challenges. This study aims to determine the improvement of students' HOTS through the application of the Bridging Analogy learning model. The research design employed a quasi-experimental approach with one experimental class and one control class. The instruments used in this study were a HOTS test for Matrix material and a student learning activity questionnaire. Research data were analyzed using statistical analysis with SPSS. The ANCOVA results showed that the Bridging Analogy learning model significantly influenced students' HOTS. The data analysis also revealed that the average HOTS score of students in the experimental class (84.73) was higher than that of the control class, which used conventional learning (55). These findings indicate that the implementation of the Bridging Analogy learning model effectively enhances students' HOTS compared to conventional learning. This research contributes to the development of innovative learning models that support the improvement of students' higher-order thinking skills in mathematics education.

Higher education in Indonesia, especially at the University of Muhammadiyah Lampung (UMLampung), is a multicultural system, where students come from various cultural, ethnic, and religious backgrounds. This diversity poses challenges in interpersonal communication between lecturers and students, especially in the context of the role of Academic Supervisors (PAs). Effective interpersonal communication is an important element in creating a harmonious learning environment and supporting academic success. This study aims to explore the role of PA lecturers in optimizing interpersonal communication to support the completion of student studies of the Communication Science Study Program at the Faculty of Social and Political Sciences (FISIP) UMLampung. The approach used is qualitative descriptive research with data collection through observation, interviews, and documentation. The results of the study show that the role of PA lecturers in interpersonal communication is very important, both in providing appropriate academic information, directing students in completing assignments, and helping to overcome problems faced by students. PA lecturers who are able to communicate effectively with students from diverse cultural backgrounds, can create supportive relationships, which contribute to the timely completion of studies. However, there are still obstacles such as time constraints and access difficulties between PA lecturers and students that need to be considered to optimize this role. This study suggests the importance of improving PA lecturers' interpersonal communication skills in order to create a more inclusive learning atmosphere and support the achievement of students' academic goals.

Oil palm production is a key driver of regional economic resilience in Indonesia, yet its predictability remains highly uncertain due to climate variability, particularly rainfall fluctuations. Although time series forecasting models such as ARIMA are widely applied, prior studies largely treatenvironmental variables as external factors rather than integrating them into a structured analytical interpretation. This study addresses this limitation by developing an environmentally-informed forecasting framework that explicitly links rainfall dynamics with oil palm production patterns using the Autoregressive Integrated Moving Average (ARIMA) approach. Secondary data from 2005 to 2024 were analyzed through a rigorous Box–Jenkins procedure, including stationarity testing, model identification, parameter estimation, and diagnostic validation. The results demonstrate that ARIMA (1,2,1) provides the most consistent representation of production dynamics, while ARIMA (0,2,2) captures rainfall variability. Forecasting results reveal a stable production trajectory over the next five years despite declining rainfall trends, indicating a decoupling pattern between environmental variability and production output. Furthermore, correlation analysis confirms a weak negative relationship, suggesting that excessive rainfall may disrupt production efficiency rather than enhance it. This study advances the existing literature by reframing time series forecasting as an integrated environmental–production system rather than a purely statistical exercise. The findings offer both methodological insight and practical relevance for improving adaptive decision-making in climate-sensitive agricultural systems

This study aims to develop and evaluate a curriculum synchronisation model between formal and non-formal education to optimise competency-based learning at the secondary school level. The research was motivated by the need to bridge the gap between competencies taught in schools and the skills required in the labour market and society. A mixed-methods approach with a sequential explanatory design was employed. Quantitative data were collected using purposive sampling through questionnaires distributed to 220 respondents, consisting of secondary school teachers, non-formal education managers, and students involved in integrated learning programs. In contrast, qualitative data were obtained through in-depth semi-structured interviews and non-participant classroom observation. Data were analysed using descriptive-inferential statistics and thematic analysis, while the validity of findings was ensured through methodological and source triangulation supported by expert judgment. The findings indicate that the implementation of the synchronised curriculum model increased students' overall competencies by 17%, with the most significant improvement observed in the psychomotor domain. Furthermore, 87% of respondents agreed that collaboration between formal and non-formal education is essential to enhance the relevance of learning. The study concludes that curriculum synchronisation effectively integrates theoretical and practical learning, strengthens institutional collaboration, and supports the implementation of competency-based education. These findings contribute theoretically to the development of integrative curriculum design and offer practical implications for adaptive and sustainable national education policies. However, this study is limited by its relatively short implementation period and its focus on a specific regional context, which may affect the generalizability of the findings.

The implementation of the Internal Quality Assurance System (SPMI) at Private Islamic Religious Higher Education Institutions (PTKIS) often faces challenges such as a weak quality culture, inconsistent follow-up, and the perception that accreditation is merely administrative. Furthermore, digitalization through the Sapto 2.0 platform has given rise to new shortcomings: reliance on a manual reminder approach in reporting lecturer grades, gaps in data markup in Student Lecture Activity (AKM) reports, and inconsistencies in the Semester Credit Unit (SKS) system during accreditation. This study aims to analyze the implementation of SPMI and responses to external quality assurance at Ma'arif University, Lampung, with a focus on the PPEPP cycle (Determination, Implementation, Evaluation, Control, Improvement). A qualitative case study approach was used. Data were collected through in-depth interviews with 10 informants (leaders, Head of LPM, heads of study programs, lecturers, and educational staff), documentation studies, and observations. The results indicate that structurally, SPMI is implemented through an annual PPEPP cycle that produces a measurable follow-up plan. However, three critical deficiencies were found: (1) the practice of marking up AKM data prior to accreditation due to target pressures and system weaknesses, (2) inconsistencies in recording credits between RPS and transcripts due to unvalidated data migration, and (3) the lack of connection between the internal quality reporting system and the graduate tracer study. The response to external quality assurance (LAMDIK assessment) provided a moment for reflection, but without transparent digital improvements, the synergy between SPMI and SPME remains vulnerable to administrative manipulation. It was concluded that continuous quality improvement in PTKIS requires a reliable electronic quality assurance system, with an audit trail, and integrated with the tracer study, not just an annual cycle formality.
