Pengaruh Aplikasi Wattpad dengan Teknik Terbimbing Terhadap Kemampuan Menulis Cerpen Siswa Kelas XI Sekolah Menengah Kejuruan Pertanian dan Pembangunan Cianjur
No full textThis study aims to examine the effectiveness of using the Wattpad application with guided techniques in improving the short story writing skills of 11th-grade students at the Cianjur Agriculture and Development Vocational School. This research employs a quantitative approach with an experimental research design. Initial observations and pretest results revealed that students’ short story writing skills were still poor, falling into the low category. To address this issue, an intervention was conducted using the Wattpad application as a digital writing medium combined with guided techniques. The posttest results showed a significant improvement in students’ writing performance. Statistical analysis confirmed a substantial increase in scores, with pretest results averaging 43.47 and posttest results increasing to an average of 72.57. The findings indicate that integrating digital platforms like Wattpad with structured guidance can enhance students’ ability to compose short stories effectively
Efektivitas Media Komik Digital Flipbook dan Gambar Berseri Terhadap Keterampilan Menulis Cerpen Siswa
No full textShort story writing is a complex skill that many students struggle to master, often resulting in a lack of enthusiasm for learning the craft in formal educational settings. This study aims to investigate the effect of flipbook-based digital comic media, the effect of serial image media, and the comparative impact of both media on the short story writing skills of Grade XI students at MAN 3 Tangerang. Employing an experimental research method with a pretest-posttest control group design, the study used a simple random sampling technique, selecting class XI Science 3 as the experimental group and XI Science 4 as the control group. Research data were collected through students’ short story writing tasks administered during both pretest and posttest stages. The findings revealed a pretest-posttest improvement in the experimental group using flipbook-based digital comics (45.40 to 71.60), while the control group using serial images improved from 43.20 to 70.60. Despite a slight performance advantage in favor of the digital comic group, the difference was not statistically significant. Therefore, both flipbook-based digital comics and serial images are equally effective in enhancing students’ short story writing skills
Penerapan Model Pembelajaran Discovery Learning untuk Meningkatkan Kemampuan Berpikir Kreatif dan Hasil Belajar Siswa dalam Menyusun Laporan Percobaan pada Siswa Kelas IX B SMP Negeri 7 Rantau Bayur
No full textThis classroom action research (CAR) investigates the effectiveness of the discovery learning model in enhancing students’ creative thinking abilities and learning outcomes, particularly in preparing experimental reports. The discovery learning model engages students in identifying concepts independently through observation and experimentation, fostering active participation and deeper understanding. The study was conducted in two cycles involving 31 ninth-grade students from Class IX B at SMP Negeri 7 Rantau Bayur, Banyuasin Regency. Data collection utilized both test and non-test techniques. The results showed significant improvements across both cycles. In Cycle I, 61% of students (19 individuals) demonstrated the ability to analyze, which increased to 96% (30 individuals) in Cycle II. Similarly, students’ ability to prepare experimental reports rose from 51% (16 students) in Cycle I to 87% (27 students) in Cycle II. These findings indicate that the implementation of the discovery learning model effectively supports the development of students’ analytical and writing skills. The learning objectives were successfully achieved by Cycle II, rendering further cycles unnecessary. This study supports the use of discovery-based instruction in improving critical competencies in science learning

Diesel Fuel Degradation Activity of Hydrocarbon-Degrading Bacteria from Nusantara Fisheries Port Brondong Lamongan
No full textThe Nusantara Fisheries Port (Pelabuhan Perikanan Nusantara - PPN) in Brondong, Lamongan Regency, is a port with high ship activities. This has led to hydrocarbon pollution in the form of diesel fuel and oil in the waters of PPN Brondong. The initial effort to address this pollution is by isolating and characterizing hydrocarbon-degrading bacteria present in these waters. This research is a strategic step in managing petroleum hydrocarbon spills in the area through bioremediation processes, either via bioaugmentation or biostimulation for further study. The research method involves isolating hydrocarbon-degrading bacteria from the waters of PPN Brondong using the spread plate isolation method. Different colony characteristics are selected for the purification of bacterial isolates. The obtained bacterial isolates are then subjected to hydrocarbon degradation activity by culturing them in a minimal medium containing diesel fuel. The degradation activity is measured using total petroleum hydrocarbon (TPH) testing. The results of this study yielded 7 different isolates from the fuel oil-contaminated sites in PPN Brondong. Culturing in a minimal medium containing diesel fuel yielded results showing that all isolates possess the ability to degrade hydrocarbons, as evidenced by the reduction in TPH

STRATEGI GURU BIMBINGAN KONSELING DALAM MENINGKATKAN PRESTASI SISWA BERSTATUS ORANG TUA CERAI BIDANG STUDI AQIDAH AKHLAK KELAS VII DI MTs. AL – ITTIHADIYAH MEDAN
No full textThis research is to describe the efforts of guidance and counseling teachers in improving the achievement of children with divorced parents in the field of Aqidah-Akhlak studies in class VII MTs. Al-Ittihadiyah-Medan. Several instruments used for data collection in this qualitative research consist of observation, interviews and data analysis. The education of children with divorced parents is the focus of this research. The family is the first and foremost place of education for children, besides that, the family is also the primary foundation for children's growth and development. So how will their education continue if the role and presence of parents is no longer clear, of course it will greatly influence the child's mental development which in turn will have an impact on their learning achievement. In this research, the discussion focuses on the role of Guidance and Counseling teachers in improving their learning achievement, especially in the Aqidah-Akhlak subjects. The results of the research show that Guidance Counseling teachers have attempted to use a personal approach to students and create a pleasant school atmosphere and establish communication with children so that it is easier for teachers to find out the problems students face. Apart from that, not all students' parents' divorce causes their learning achievement to decline because children's learning achievement does not entirely depend on the presence of their parents, but also depends on the child's own desire to change, which plays an important role in increasing learning achievement. Guidance Counseling teachers strive to support success through motivation, instilling an attitude of enthusiasm, self-confidence and at the same time providing continuous support to children so that they are able to change themselves in a better direction, not because they think about themselves and feel alone.
