Abstract

Toddlers in Indonesia are an age group that is vulnerable to the impacts of malnutrition. Central Java Province is the province with the highest number of cases of malnutrition in toddlers in Java, namely 9525 cases of malnutrition during 2023. This study aims to analyze the variables that influence malnutrition in Central Java Province in 2023. The data used are secondary data in 2023sourced from the Badan Pusat Statistik (BPS), Central Java Provincial Health Service, and Badan Panga Nasional (BPN). The analysis method used is negative binomial regression for modeling enumeration data to overcome the problem of overdispersion in Poisson regression. The results of the analysis show that there is a negative influence of the variables of the percentage of households with access to proper sanitation, the food security index, and the percentage of babies receiving exclusive breastfeeding on the number of cases of malnutrition in toddlers. Meanwhile, the proportion of women aged over 15 years who have a maximum junior high school diploma has an effect on increasing cases of malnutrition in toddlers.

Abstract

Education is a national development priority that is a strategic element in promoting the adoption of modern technology and sustainable growth, as reflected in National Long-Term Development Plan (RPJPN) 2025–2045 and the fourth Sustainable Development Goal (SDG). However, educational inequality in Papua and West Papua remains a serious challenge in terms of equitable access to quality education. This study aims to evaluate the impact of digital development on educational inequality in these two provinces. Secondary data from the Central Statistics Agency (BPS-Statistics) and the Directorate General of Fiscal Balance (DJPK) were analyzed using the Spatial Error Model (SEM) to examine the influence of Information and Communication Technology (ICT) on the Education Gini Coefficient (EGC). The results show that variables such as internet access for people aged 7-18 years, the Community Literacy Development Index (IPLM), Mean Years of School (MYS), and regional education budgets play a significant role in reducing educational inequality. These findings confirm that digital development plays a strategic role in creating an inclusive and equitable education system. This research is expected to serve as a basis for formulating adaptive technology-based education policies to overcome educational inequality in Papua Island.

Abstract

Transformasi pondok pesantren menuju kemandirian ekonomi memerlukan integrasi kecakapan hidup melalui paradigma Santri-Preneur. Program pengabdian ini bertujuan meningkatkan keterampilan vokasional santri Pondok Pesantren Bustanul Muta’allimat Blitar dalam memproduksi pakan ternak kambing berkualitas berbasis limbah lokal. Metode pelaksanaan menggunakan pendekatan Participatory Rural Appraisal (PRA) dan Experiential Learning melalui skema pendidikan, pelatihan, serta pendampingan. Intervensi dilakukan dengan proporsi 30% teori dan 70% praktik produksi silase. Hasil pengabdian menunjukkan capaian yang komprehensif. Secara kognitif, terjadi peningkatan pemahaman teknologi pakan sebesar 63,1%, dengan skor rata-rata naik dari 51,5 (pre-test) menjadi 84,0 (post-test). Pada aspek psikomotorik, santri berhasil mencapai kompetensi sangat memuaskan dengan nilai 86,25, terutama pada akurasi formulasi dan pengemasan anaerobik. Kualitas output pakan mencapai skor organoleptik 93,12 berkat aroma fermentasi ideal dan bebas kontaminasi jamur.Kesimpulannya, sinergi bioteknologi sederhana dan optimalisasi limbah lokal efektif membangun ekosistem ekonomi pesantren mandiri. Program ini membekali santri dengan life skills relevan, serta memodernisasi peternakan secara berkelanjutan.

Abstract

This study aims to analyze in depth the phenomenon of student deviant behavior at SMP Negeri 7 Blitar City, including the causal factors, forms of violations, impacts, prevention methods, obstacles, and solutions. The research method uses a qualitative single case study. Informants were selected intentionally through purposive and snowball sampling techniques, involving the principal, vice-president of student affairs, guidance counselors, homeroom teachers, subject teachers, and student perpetrators. Data were collected through in-depth interviews, direct observation, and documentation of violation records for 39 students. The research procedure includes four stages: instrument preparation, six-month field implementation, data analysis of the Miles, Huberman, and Saldana model (condensation, presentation, conclusion) tested through source/technique triangulation, and final reporting. The results show that violations are triggered by internal factors (unstable emotions) and external factors (broken homes, peers, and social media). The forms vary from minor violations in open areas (truancy, swearing) to serious violations in quiet places (smoking, fighting, damaging facilities). The novelty of this research is the success of mapping that the type of student delinquency is influenced by the physical location in the school (crowded vs. quiet places) as well as the influence of current digital trends. The theoretical implication is that this research enriches social science regarding child behavior control in schools in the modern era. The practical implication is that this research becomes a real guide for schools to create zoning-based rules, helps BK teachers design heartfelt guidance, and invites parents to work together to supervise their children humanely.

Abstract

This study focuses on analyzing the effectiveness of the Problem Based Learning (PBL) model integrated with a deep learning approach in accelerating students’ creative thinking ability in the Pancasila Education subject. Using a quantitative quasi-experimental design, the research, which ran for eight months from November 2025 to June 2026, involved a population of 254 eighth-grade students at SMPN 8 Blitar. Through the application of a cluster random sampling technique, 64 students were selected as the sample and distributed evenly into an experimental class that received deep-learning-based PBL treatment and a control class that was taught using the conventional method. Primary data were collected using a creative-thinking test instrument, which was subsequently analyzed through the Independent Samples t-Test and N-Gain calculation. The empirical findings confirmed a significant difference in achievement between the two groups (Sig. = 0.000 < 0.05), with the experimental group’s mean posttest score of 88.00 significantly outperforming the control group, which only achieved 75.94. The experimental group also showed a high level of effectiveness, obtaining a mean N-Gain Score of 0.7527. The novelty of this research lies in the modification of the PBL syntax that synergizes the three pillars of deep learning—mindful, meaningful, and joyful learning—which provides practical implications for educators in transforming the classroom into a contextual learning environment. Based on these results, it is concluded that the implementation of a deep-learning-oriented PBL model is highly effective in boosting students’ creative thinking skills.

Abstract

The low critical thinking ability of Grade X students at MA Ma'arif NU Kota Blitar in the Pancasila Education subject motivated this quasi-experimental study using a nonequivalent control group design. The study aimed to test the effectiveness of the Problem Based Learning (PBL) model using samples from class X.F (25 students, experimental group) and class X.B (25 students, control group) selected through purposive sampling. The novelty of this research lies in the localization of the subjects in a private Islamic senior high school (Madrasah Aliyah) with a distinctive religious culture. Data were collected through HOTS essay tests and analyzed using the t-test and Normalized Gain (N-Gain). The results showed that the implementation of the PBL model fell into the very good category (92.86%). Although the t-test proved there was no statistically significant comparative difference in critical thinking between the groups (p = 0.113 > 0.05) due to the limited adaptation period, the internal analysis of the experimental class recorded an average N-Gain score of 0.58 (moderate improvement category). The theoretical implication of this research confirms that the effectiveness of PBL is not absolute but strongly depends on students' initial cognitive readiness. Practically, this research guides teachers to integrate strong structured guidance (scaffolding) at the beginning of the PBL syntax to trigger independent thinking within the Kurikulum Merdeka (Independent Curriculum).
