PERLINDUNGAN LINGKUNGAN MARITIM INDONESIA: REGULASI PENCEGAHAN PENCEMARAN LAUT OLEH KAPAL
No full textSebagai negara kepulauan terbesar di dunia, Indonesia berada pada posisi strategis yang menjadikannya jalur penting pelayaran internasional. Namun, tingginya lalu lintas maritim ini membawa dampak besar terhadap ekosistem laut yang rentan. Tulisan ini bertujuan untuk menganalisis dan menjabarkan kerangka hukum perlindungan lingkungan maritim secara komprehensif di Indonesia, yang merupakan negara kepulauan strategis dengan lintasan pelayaran internasional yang padat. Penulisan ini menggunakan metode yuridis normatif dengan menelaah peraturan perundang-undangan, peraturan pemerintah, serta kebijakan menteri, terutama yang diatur dalam Undang-Undang No. 17 Tahun 2008 tentang Pelayaran beserta regulasi turunannya. Fokus pembahasan meliputi upaya pencegahan dan penanggulangan pencemaran dari pengoperasian kapal, kegiatan kepelabuhanan, pembuangan limbah ke laut, serta penutuhan kapal. Hasil penulisan menunjukkan bahwa kerangka hukum Indonesia telah mengatur secara ketat standar operasional dan prosedur pelayaran, termasuk sistem manajemen limbah, alat pengendali pencemaran, sertifikasi wajib, serta rencana tanggap darurat. Tanggung jawab hukum ditegaskan melalui kewajiban asuransi dan sistem koordinasi tanggap darurat berjenjang antara otoritas pelabuhan dan pemerintah pusat. Selain itu, regulasi domestik telah mengadopsi berbagai ketentuan internasional seperti Konvensi MARPOL, yang menjamin keselarasan dengan upaya global perlindungan lingkungan laut. Penulisan ini menemukan bahwa meskipun perangkat hukum sudah cukup lengkap, pelaksanaannya masih menghadapi hambatan teknis dan keterbatasan pengawasan. Disarankan adanya penguatan kapasitas institusi, peningkatan sistem pemantauan, serta kolaborasi multipihak. Secara keseluruhan, tulisan ini menekankan bahwa perlindungan lingkungan maritim yang efektif sangat penting untuk menjaga keanekaragaman hayati laut dan mendukung keberlanjutan manfaat ekonomi maritim Indonesia.

The Effect of The Optimum Performance Training Model on Increasing Agility In Female Futsal
Full text linkThis study aims to evaluate the effect of the Optimum Performance Training (OPT) training model on improving anaerobic ability, especially in the aspect of agility in female futsal athletes of UKM UPI. The method used is ex post facto, where researchers cannot manipulate data. The research sample consisted of 9 female futsal athletes, and agility measurements were made using the shuttle run test. The pretest results showed an average value of 7.07 with a standard deviation of 0.32924, while the posttest showed an average value of 6.87 with a standard deviation of 0.43162. The minimum pretest value was 6.70 and the maximum was 7.60, while the posttest showed a minimum value of 6.20 and a maximum of 7.59. Hypothesis testing using the paired sample test resulted in a t value of 3.682 and a Sig. (2-tailed) value of 0.006, which indicates that H0 is rejected. Thus, it can be concluded that the application of the OPT training model has a significant effect on increasing agility in UPI female futsal players. This research provides an important contribution to the development of a more effective futsal training program to improve athlete performance

APPLIED LINGUISTICS: TRIADIC SIGN MODELS IN PERSUASION METHODS OF NIVEA MEN’S PRODUCT PACKAGING
Full text linkThis study aims to analyze the use of signs on Nivea Men product packaging, focusing on their interpretation and effectiveness in delivering persuasive messages. Employing Charles Sanders Peirce’s Triadic Relation Theory, a qualitative method was used to examine product categories and their connection to everyday experiences. Data were collected through observation and documentation from Nivea Men’s official website, then analyzed using triadic theory and persuasion methods. The results reveal that signs significantly influence consumer interpretation and the persuasive value of products, although some signs do not fully align with their intended meanings. This study highlights the importance of designing clear and purposeful signs to enhance advertising strategies and consumer understanding. Future research should focus on refining semiotic and persuasion techniques to align signs more effectively with product identity and market needs

Based on the normality test, it is stated that the sample comes from a normal population. Based on the homogeneity test, it is stated that the sample comes from a homogeneous population, then based on the hypothesis test, the sig value is known. (2-tailed) with t-test is 0.000. Because the probability value is less than 0.05, and the calculated t value is 4.497 > ttable is 1.674. Thus Ho (null hypothesis) is rejected and Ha (alternative hypothesis) is accepted. Based on the results of the analysis and discussion of test data, it can be concluded that there is an influence after being treated using folding paper crafts media on the learning outcomes of grade V Mathematics at Elementary School 141 Palembang
Diversity of Secondary Metabolites of Eurycoma Longifolia and Its Prospects as Anticancer Agents Based on Sumatran Bioresources: A review
Full text linkEurycoma longifolia, commonly known as Tongkat Ali or Pasak Bumi, is a traditional medicinal plant widely used in Southeast Asia, including Sumatra, Indonesia. It is traditionally recognized for its aphrodisiac and general health-promoting properties. However, recent phytochemical and pharmacological studies have identified a diverse range of secondary metabolites in this plant, such as quassinoids, alkaloids, triterpenes, and squalene derivatives, that exhibit promising anticancer activities. This review aims to comprehensively explore the diversity of secondary metabolites found in E. longifolia populations in Sumatra and assess their potential as anticancer agents by analyzing local bioresources. A systematic literature review was conducted by collecting data from scientific databases including PubMed, ScienceDirect, and Google Scholar using targeted keywords. Selection criteria focused on studies discussing secondary metabolite content, anticancer mechanisms, toxicological data, and drug development potential. The findings show that several compounds in E. longifolia can inhibit cancer cell proliferation, induce apoptosis, and prevent angiogenesis and metastasis in vitro and in vivo. Despite challenges such as low bioavailability and lack of clinical trials, the plant’s abundant presence in Sumatra and the bioactivity of its metabolites make it a promising candidate for the development of novel, plant-based anticancer therapies. Further research and standardization are recommended to optimize its pharmaceutical application
