Abstract

The Bumang River is one of the rivers on Bangka Island that has not been affected by tin mining. Several fish species have been reported in this river, including Osteochilus spilurus, Pristolepis grooti and Brevibora cheeya. This study aims to inventory and re-update the composition of fish species in the Bumang River, Bangka Island. Exploration and identification of freshwater fish were carried out in June - August 2025. The location of the fish exploration in the Bumang River is in Kemuja Village, West Mendo District, Bangka Regency with coordinates 2 ° 5′ 8.48 ″ S, 105 ° 57′ 24.55 ″ E. This study uses a descriptive exploratory. Exploration of fish samples from several points in the river using umbrella traps. The fish obtained will be identified and water quality measurements will be carried out directly in the waters where the traps are installed. A total of 37 species and 7 families of fish were collected during the research. Among the seven families identified, the Cyprinidae family had the largest number of species, with 12, followed by the Osphronemidae family with 7 species, and the remaining families with only 1 to 3 species. The high number of species and families identified indicates that the Bumang River has a high fish diversity and the diversity of fish in this river is also enriched by the presence of endemic species, namely: Betta schaleri, Betta chloropharynx, and Parospremenus bintan.

Abstract

This research focuses on discussing typical traditional foods made from fish originating from the islands of Bangka and Belitung. The aim is to find out the differences in the ingredients and the process of making Bangka and Belitung traditional foods, namely Lempah Kuning and Gangan. Lempah kuning is a very famous speciality among the people of Bangka, and Gangan is a speciality food whose main ingredient is made from fish originating from Belitung Island. This research uses a qualitative research type method with data collection methods in the form of observation and also conducting interviews with sources. Lempah Kuning from Bangka and Gangan from Belitung have differences in the types of spices and cooking methods. Lempah Kuning uses Belimbing Wuluh and Gangan utilises the acid from Pineapple. Lempah Kuning uses fish ingredients, while Gangan cooks fish, beef, chicken and duck. The resulting flavours and aromas are different.

Abstract

Penelitian ini bertujuan mengidentifikasi strategi pemasaran Butik Venni (berdiri sejak 1996 di Samarinda) untuk mempertahankan eksistensi dan daya saing. Strategi utama butik meliputi: inovasi produk (mengikuti tren, layanan kustomisasi), kualitas bahan premium (nyaman, aman, tahan lama), dan promosi digital (via Instagram) untuk memperluas jangkauan. Hasil penelitian menunjukkan bahwa sinergi ketiga faktor tersebut (diperkuat oleh wawancara pelanggan dan data penjualan) berhasil meningkatkan kepuasan dan loyalitas pelanggan, memperkuat citra merek, serta menciptakan daya saing berkelanjutan. Peningkatan omzet tertinggi tercatat Rp26.124.900 pada bulan Agustus, mayoritas dari pesanan seragam/kebaya. Rekomendasi penelitian: Butik Venni disarankan untuk terus memperluas inovasi desain, memperkaya variasi produk/layanan, mengoptimalkan promosi digital dengan kolaborasi/fitur interaktif, dan meningkatkan sistem pencatatan data penjualan/pelanggan secara digital.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penerapan model Problem Based Learning (PBL) terhadap hasil belajar peserta didik pada materi isu-isu lingkungan, serta mengukur peningkatan hasil belajar setelah perlakuan. Penelitian menggunakan pendekatan kuantitatif dengan metode kuasi eksperimen dan desain Pretest-Posttest Control Group Design. Populasi penelitian adalah seluruh peserta didik kelas IX SMP Negeri 36 Makassar tahun ajaran 2025/2026 yang berjumlah 288 orang. Sampel dipilih secara purposif, dengan kelas IX.5 sebagai kelas eksperimen (n=32) dan kelas IX.6 sebagai kelas kontrol (n=32), berdasarkan kesetaraan kemampuan akademik dan rekomendasi guru. Instrumen berupa 20 soal pilihan ganda yang telah divalidasi oleh ahli dan diuji reliabilitasnya. Hasil analisis menunjukkan bahwa rata-rata posttest kelas eksperimen (65,22) lebih tinggi dibandingkan kelas kontrol (59,47). Hasil uji Independent Samples t-Test menunjukkan t hitung (2,315) lebih besar dari t tabel (2,000) pada derajat bebas 62 dengan signifikansi 0,024 (p<0,05), serta nilai mean difference sebesar 5,75. Hasil tersebut mengindikasikan bahwa penerapan PBL memberikan pengaruh signifikan terhadap peningkatan hasil belajar peserta didik pada materi isu-isu lingkungan. Temuan ini memperkuat efektivitas PBL sebagai model pembelajaran yang berpusat pada peserta didik dan kontekstual, namun generalisasi hasil tetap perlu dilakukan secara hati-hati mengingat keterbatasan desain dan sampel.

Abstract

Stainless steel 304 (SUS 304) is widely used for food containers because of its corrosion resistance and suitability for food-contact applications. However, the occurrence of denting, wrinkling, and permanent deformation in some products suggests possible variations in material quality and mechanical performance. This study compared the chemical composition and mechanical properties of two types of SUS 304 food containers, designated Type 1 and Type 2. Chemical composition was determined using optical emission spectroscopy, while mechanical properties were evaluated through tensile testing in accordance with ASTM E8/E8M and deflection testing using the three-point bending method. The evaluated parameters comprised yield strength, ultimate tensile strength, elongation, maximum force, deflection modulus, and deflection strength. Chemical analysis confirmed that all specimens satisfied the compositional requirements for stainless steel 304 specified in ASTM A240. The mechanical test results showed that Type 1 specimens had greater tensile strength than Type 2 specimens. Type 1 also exhibited higher deflection modulus and deflection strength, although Type 2 recorded a slightly higher average maximum force. These findings indicate that Type 1 food containers possess greater stiffness and resistance to deformation and therefore demonstrate superior overall mechanical quality compared with Type 2 products. The study provides an evidence-based framework for evaluating material performance and strengthening quality-control procedures for SUS 304 food containers.

Abstract

The development of information and communication technology has provided various conveniences for society, but on the other hand, it has also given rise to various forms of cybercrime, one of which is child cybergrooming. This crime is an act of perpetrators who use social media or other digital platforms to approach, build trust, and manipulate children for the purpose of exploitation or sexual disclosure. This study aims to discuss the contribution of cyber law in handling cases of child cybergrooming that are increasingly occurring in society and examine the form of legal protection for child victims. The research method used is normative juridical with a qualitative approach. Data were obtained through a literature review sourced from regulations, books, scientific journals, and various legal literature relevant to the problem studied. The results of the study indicate that cyber law in Indonesia plays a significant role in efforts to overcome child cybergrooming through regulations in Law Number 1 of 2024 concerning Information and Electronic Transactions and Law Number 17 of 2016 concerning Child Protection. Perpetrators can be subject to sanctions in the form of imprisonment and fines in accordance with applicable provisions. In addition to repressive efforts through law enforcement, prevention is also a crucial aspect, including parental supervision, education on safe and wise internet use, increased digital literacy, and outreach to children and the community about the dangers of cybercrime. Thus, cyber law serves not only as an instrument for prosecution against perpetrators but also as a means of protection and prevention to create a safe digital space for children. Synergy between the government, law enforcement officials, educational institutions, families, and the community is necessary to minimize cases of child cybergrooming and ensure the fulfillment of children's rights in the digital age.
