Dampak Pemidanaan Anak Yang Berhadapan Dengan Hukum Yang Melakukan Tindak Pidana Narkotika
Get PDFPerkembangan teknologi serta informasi berdampak pada tidak terkontrolnya pergaulan di lingkungan remaja, bukan hanya pada anak-anak yang putus sekolah, melainkan telah menjalar ke kalangan pelajar yang masih masuk dalam klasifikasi Anak. Penelitian ini memiliki tujuan untuk melakukan analisis pengaturan hukum dan bentuk pemidanaan serta dampak terhadap anak yang terlibat dalam penyalahgunaan narkotika, serta untuk mengidentifikasi unsur-unsur yang menyebabkan anak dapat terjerumus ke dalam tindakan tersebut. Penelitian ini dilatarbelakangi oleh semakin meningkatnya kasus penyalahgunaan narkotika oleh anak, yang menimbulkan keprihatinan terkait perlindungan hukum bagi anak serta efektivitas sistem peradilan pidana anak di Indonesia. Metode penelitian yang digunakan adalah metode yuridis empiris dengan menganalisis fakta-fakta yang terjadi di lapangan. Hasil penelitian menunjukkan bahwa pengaturan hukum terkait anak yang terlibat penyalahgunaan narkotika telah tertuang dalam Undang-Undang Nomor 35 Tahun 2009 tentang Narkotika dan Undang-Undang Nomor 11 Tahun 2012 tentang Sistem Peradilan Pidana Anak. Namun dalam praktiknya, pendekatan pemidanaan terhadap anak masih cenderung represif. Diversi dan rehabilitasi belum sepenuhnya menjadi prioritas. Dampak dari sistem pemidanaan terhadap anak tidak hanya berhenti pada proses peradilan dan pelaksanaan hukuman, tetapi juga harus memperhatikan keberlanjutan kehidupan anak setelah menjalani pidana. Oleh karena itu, diharapkan adanya regulasi atau peraturan yang secara tegas mengatur langkah-langkah pembinaan pasca-pemidanaan. Regulasi tersebut harus menjamin bahwa anak, setelah menyelesaikan masa pidananya, memperoleh solusi konkret untuk dapat melanjutkan kehidupannya secara lebih baik, baik melalui pendidikan, pelatihan keterampilan, maupun program reintegrasi sosial.

Pengembangan LKPD IPA Berorientasi Keterampilan Proses Sains Materi Gaya untuk Meningkatkan Pengetahuan Faktual dan Konseptual Kelas IV SD
Get PDFThis research and development study aims to produce a science student worksheet oriented toward science process skills that is valid, practical, and effective in improving elementary students' factual and conceptual knowledge. Existing worksheets did not incorporate science process skill indicators, resulting in students lacking training in essential scientific skills. The study utilized the ADDIE development model, which includes five stages: Analysis, Design, Development, Implementation, and Evaluation. Data were collected through observations, interviews, questionnaires, and tests (pre-tests and post-tests) to assess students’ understanding. Data analysis involved calculating percentages and value ranges at both classical and individual levels. The research subjects were fourth-grade students from two elementary schools. A limited trial was conducted at SD Negeri 2 Sumber Makmur, while effectiveness testing took place at SD Negeri Nibung. The results showed that the implementation of the science process skills-oriented LKPD was effective in enhancing students' factual and conceptual knowledge. This effectiveness is evidenced by an N-Gain score of 0.7288 (high category) for factual knowledge and 0.693 (moderate category) for conceptual knowledge. Based on these findings, it is recommended that teachers adopt science process skill-oriented worksheets to actively involve students in learning activities and promote better understanding of scientific concepts and facts.This research and development study aims to produce a science student worksheet oriented toward science process skills that is valid, practical, and effective in improving elementary students' factual and conceptual knowledge.

Challenges for Employee Class Students in Aquatics Lectures in Terms of Time Management
Get PDFThis study aims to evaluate the challenges faced by employee class students in aquatic lectures in terms of time management. Time management here is defined as the decision-making process to organize and adjust time according to changing needs. Employee class students face challenges in dividing their time between work, study, and practical activities that require physical presence. The method used is descriptive quantitative with a questionnaire covering four aspects including time management, time protection, time adaptation, and time use effectiveness. The sample consisted of 40 students who contracted the Aquatic Learning course. The results showed that students' time management skills were in the fairly good category, with an average score of 2.95 on a scale of 1 to 4. The aspects of time management and effectiveness received high scores, while time protection was an area that needed improvement. These findings indicate that although students have basic skills in time management, additional strategies are needed to improve consistency and focus in practical learning
The Relationship Between Leg Muscle Power and Shooting Performance in Soccer Among 10th Grade in Senior High School
Get PDFThis study investigates the relationship between leg muscle strength and shooting accuracy in soccer among 10th-grade students at Senior High School 1 Pagelaran using a quantitative correlational design. The population consisted of all 10th-grade students participating in physical education, with a purposive sample of 36 students. Data were collected using a leg dynamometer to measure leg strength and a partitioned goal test to assess shooting accuracy. The data were analyzed using the Pearson Product Moment correlation test with SPSS version 27 after fulfilling normality and linearity requirements. The results revealed a very strong and significant correlation between leg muscle strength and shooting accuracy, with a correlation coefficient (r) of 0.925 and a significance value of 0.000 < 0.05. These findings suggest that students with greater leg muscle strength demonstrate higher shooting accuracy in soccer, supporting the biomechanical theory that leg strength contributes to power generation, stability, and ball control during kicking. Thus, it can be concluded that leg muscle strength plays a crucial role in enhancing shooting accuracy. The findings are expected to assist physical education teachers in designing structured training programs to improve students’ soccer performance.Penelitian ini meneliti hubungan antara kekuatan otot tungkai dan ketepatan menendang bola dalam permainan sepak bola pada peserta didik kelas X di SMAN 1 Pagelaran dengan menggunakan desain penelitian kuantitatif korelasional. Populasi penelitian mencakup seluruh peserta didik kelas X yang mengikuti pembelajaran pendidikan jasmani, dengan sampel purposive sebanyak 36 peserta didik. Data dikumpulkan menggunakan leg dynamometer untuk mengukur kekuatan otot tungkai dan tes menembak ke gawang bersekat untuk menilai ketepatan menendang bola. Analisis data dilakukan menggunakan uji korelasi Pearson Product Moment dengan bantuan program SPSS versi 27, setelah memenuhi syarat normalitas dan linearitas. Hasil penelitian menunjukkan adanya korelasi yang sangat kuat dan signifikan antara kekuatan otot tungkai dan ketepatan menendang bola, dengan koefisien korelasi (r) sebesar 0,925 dan nilai signifikansi 0,000 < 0,05. Temuan ini menunjukkan bahwa peserta didik dengan kekuatan otot tungkai yang lebih besar memiliki ketepatan menendang bola yang lebih tinggi dalam sepak bola, mendukung teori biomekanika yang menyatakan bahwa kekuatan tungkai berkontribusi terhadap pembentukan tenaga, stabilitas, dan kontrol bola saat menendang. Dengan demikian, dapat disimpulkan bahwa kekuatan otot tungkai memiliki peran penting dalam meningkatkan ketepatan menendang bola. Hasil penelitian ini diharapkan dapat membantu guru pendidikan jasmani dalam merancang program latihan terstruktur untuk meningkatkan performa sepak bola peserta didik
