Abstract

Graphene was successfully synthesized from chicken feather biomass waste using the Liquid Phase Exfoliation (LPE) method assisted by Linear Alkylbenzene Sulfonate (LAS) surfactant at varying volumes of 1 mL, 1.5 mL, and 2 mL. The aim of this study was to evaluate the potential of chicken feather-derived graphene as an electrode material for rechargeable batteries. Characterization using UV-Visible spectrophotometry showed a distinct absorption peak at approximately 270 nm, corresponding to the π→π* electronic transition, with increasing absorbance intensity observed with higher surfactant volumes, indicating more effective graphene exfoliation. XRD analysis revealed a shift in diffraction peaks to lower 2 angles, increased interlayer spacing (d-spacing), and the largest crystallite size of 13.58 nm at a surfactant volume of 1.5 mL. These results indicate that the surfactant plays a critical role in stabilizing and forming the crystalline structure of graphene. Overall, this study demonstrates that chicken feather-based graphene has promising potential to be developed as an eco-friendly electrode material in rechargeable battery applications

Abstract

Selama ini pembelajaran membaca al-Qur’an di TPQ Jalaluddin sudah berjalan baik sesuai dengan petunjuk dan panduan yang terdapat di dalam buku metode qiroati itu sendiri. Namun jika ditinjau dari manajemen kelas (pengelolaan kelas) maka dapat dikemukakan bahwa pembelajaran al-Qur’an di TPQ tersebut adalah kurang kondusif dan efektif, terbukti masih adanya santri yang ramai, berbicara sendiri, kurang fokus dan tidak memperhatikan bahkan menggangu teman selama pembelajaran al-Qur’an berlangsung. Oleh karena itu, penulis tertarik untuk melaksanakan kegiatan pengabdian kepada masayarakat di TPQ Jalaluddin Dusun Diwet Kelurahan Pogar Kecamatan Bangil Kabupaten Pasuruan. Kegiatan ini bertujuan untuk meningkatkan pengetahuan dan pemahaman tentang peningkatan keterampilan guru mengelola kelas dalam pembelajaran al-Qur’an. Metode yang digunakan adalah mengumpulkan para guru TPQ Jalaluddin, kemudian diberikan penyuluhan tentang peningkatan keterampilan guru mengelola kelas dalam pembelajaran al-Qur’an.. Penyuluhan menggunakan metode ceramah, tanya jawab dan evaluasi. Tingkat pengetahuan responden dapat diketahui dengan dilakukan pre test sebelum kegiatan dan post tes sesudah kegiatan. Hasil kegiatan ini adalah adanya peningkatan pengetahuan dan pemahaman tentang peningkatan keterampilan guru mengelola kelas dalam pembelajaran al-Qur’an. Hasil luaran dari kegiatan ini adalah laporan yang akan dipublikasikan di jurnal nasional atau prosiding nasional, hak kekayaan intelektual, video kegiatan (youtube), dan media massa online atau offline, dan peningkatan pengetahuan dan pemahaman responden serta perubahan perilaku.

Abstract

It is very challenging for a teacher to teach students with special needs, for example those with Autism Spectrum Disorder (ASD), so that they can learn and get a proper education. ASD students have poor communication and interaction skills. This can be a problem for teachers in the teaching process because their mastery in teaching English strategies to ASD students is low. Teaching ASD students is different from teaching other students in general because English teachers must have special guidelines for teaching strategies. The solution to help is to equip them with the right teaching strategies. Teaching strategies are the structures, systems, methods, techniques, procedures, and processes that teachers use during teaching as a way to help students learn better. There are five teaching strategies for ASD students by applying: 1. Total Physical Response (TPR), 2. Contextual Teaching Learning (CTL) approach, 3. Image media with play techniques, 4. RPP according to the needs of ASD students, 5. Video Recording Method Interactive. The socialization of community service was oriented to focus on strategies for teaching English for ASD students to English teachers at the Musyawarah Kerja Kepala Sekolah (MKKS) Private Junior High School association in the North Surabaya region. The target participants for this activity were 40 junior high school teachers from various schools who are members of the association, but in fact there were 97 people who attended this seminar. This study aimed to determine teachers' perceptions in teaching English language strategies to students with ASD. This study used qualitative research methods by describing the results of teachers' perceptions obtained from interview with them. The findings of this study indicated that teachers' perceptions were positive regarding this matter. The data collection method was carried out by interviewing five English teachers randomly. Data analysis was carried out by describing the data from the interviews. The results indicated that the English teacher's perception of this community service activity was positive to increase English teachers' mastery in teaching English language strategies to ASD students so that they can teach with appropriate teaching strategies.

Abstract

Hypercholesterolemia is a growing health problem, including among adolescents in Islamic boarding schools (pesantren) where diets are high in fat and low in fiber, and physical activity is limited. This condition carries a risk of developing cardiovascular disease, necessitating preventive interventions tailored to the characteristics of the Islamic boarding school community. This Community Service (PkM) activity aims to increase students' knowledge and awareness of high cholesterol prevention through healthy lifestyle education and the use of bay leaves (Syzygium polyanthum) as an alternative herbal cholesterol-lowering agent. The program's innovation lies in integrating evidence-based health education with local wisdom, making it easily implemented in Islamic boarding schools. The activity was conducted at the Zainul Hasan Genggong Islamic Boarding School in Probolinggo in May 2025, involving 30 students and 14 religious teachers. The methods used included an initial survey, FGDs, interactive counseling with pre- and post-test evaluations, and free health checks, including anthropometry, blood pressure, and blood sugar measurements, medical consultations, and medication administration. The primary outcome was increased participant knowledge, measured by comparing pre-test and post-test scores and baseline health data from the examination. The results of the activity showed an average increase in participant knowledge of 23.4 points between the pre-test and post-test. Students also gained practical skills in using bay leaves as a daily ingredient beneficial for health.

Abstract

One of the major social issues currently faced in Indonesia, particularly in Pasuruan Regency, is intolerance. Educational institutions play a strategic role in instilling values of tolerance to reduce intolerant attitudes, especially from early childhood education. However, early childhood education institutions in Pasuruan Regency face challenges related to educators’ limited understanding of how to foster tolerant attitudes among young children. This community service activity aimed to enhance the knowledge and understanding of early childhood educators regarding the formation of tolerant attitudes in early childhood learners. The program was conducted over four months and involved early childhood educators in Pasuruan Regency, totalling 50 participants. The method employed was educational counseling delivered through lectures and question-and-answer sessions. Participants’ knowledge levels were measured using a pre-test questionnaire prior to the counseling session and a post-test afterward to assess knowledge improvement. The results indicated that only 10 participants (20%) demonstrated adequate knowledge in the pre-test, while post-test results showed a significant increase, with 40 participants (80%) demonstrating improved understanding. In conclusion, educational counseling activities for early childhood educators in Pasuruan Regency effectively increased their knowledge in fostering tolerant attitudes among early childhood learners.

Abstract

This study aims to determine the effect of daily prayer habituation on the development of religious and moral values in children aged 4–5 years at TK Yamassa Surabaya. The background of this research is the increasing use of digital technology, which has led to a decline in social interaction and children's understanding of religious and moral values. Preliminary observations indicated that some children had not yet developed the ability to recite daily prayers properly due to inappropriate behavior. The research uses a quantitative approach with a one-group pretest-posttest pre-experimental design. The sampling technique used was saturated sampling. Data collection was conducted through observation and documentation. Data analysis included descriptive analysis, Normality Test, Homogeneity Test, and t-Test using IBM SPSS version 30. The results of the descriptive analysis showed an average pre-test score of 9.60 and a post-test score of 16.05. The normality test (Shapiro-Wilk) indicated that the data were normally distributed, with a pre-test value of 0.087 and a post-test value of 0.116. The homogeneity test showed that the data were homogeneous with a value of 0.175 > 0.05. The t-test showed a significance value of 0.001 < 0.05, which means there is a significant effect of daily prayer habituation. Based on these results, it can be concluded that daily prayer habituation has an effect on the development of religious and moral values in children aged 4–5 years at TK Yamassa Surabaya. It is suggested that educators, schools, and future researchers be more innovative in developing daily prayer habituation through various activities.
