Abstract

Purpose: This study was conducted to assess prevalence and antibiotic resistance profile of E. coli from ready-to-eat crispy fried chicken (CFC) in Jember city, Indonesia. Methods: This cross-sectional study was conducted from November 2020 to April 2021 by collecting a total of 81 CFC samples from 27 food stalls in campus area using a simple random sampling method. Isolation and determination of E. coli use were performed by conventional culture method and an antibiotic susceptibility test was conducted by using Kirby Bauer disk diffusion method on the Mueller–Hinton agar. Result: Out of 81 CFC samples, 77 (95.06%) were positive for E. coli. High E. coli drug resistance was observed on ampicillin, amoxicillin, (100%) followed by cefixime (98.72%), erythromycin (97.59%), sulfamethoxazole (93.59%), azithromycin (83.33%), cefotaxime (78.28%), chloramphenicol (75.64%), and cefixime (74.36%). On the other hand, there was the highest susceptibility for ciprofloxacin (64.10%). Multidrug resistance was also found in 76/77 (98.70%) of the isolates. MAR index was 0.4-1. Conclusion: The resistance pattern CfmCroAmlAmpAzmCtxSxtCE was the most common among the E. coli isolates, with 17 showing it. The multiple antibiotic index (MAR index) ranged from 0.4 to 1. Hygienic measures should be rigorously implemented, and monitoring resistance of E. coli is required to reduce the risks related to the emergence of multi-resistant bacteria.

Abstract

Penelitian ini berjudul “Analisis kerusakan tutup palka terhadap kontruksi ruang muat kapal pada MV Oriental Jade”. Penelitian ini bertujuan untuk menganalisis faktor penyebab kerusakan tutup palka dan dampaknya terhadap konstruksi ruang muat kapal pada MV Oriental Jade. Metode yang digunakan adalah pendekatan kualitatif dengan studi kasus, melalui observasi langsung, wawancara dengan awak kapal, serta dokumentasi kondisi fisik di lapangan. Hasil penelitian menunjukkan bahwa kerusakan tutup palka disebabkan oleh beberapa faktor utama, yaitu: korosi berat pada permukaan pelat baja, penggunaan rubber seal yang telah melebihi usia pakai, beban muatan yang melebihi batas kekuatan struktur, serta kurangnya sistem perawatan yang terstruktur dan hanya bergantung pada Planned Maintenance System (PMS) tanpa inspeksi aktual secara visual. Dampak dari kerusakan tersebut meliputi korosi pada lantai (tank top), dinding palka, serta dudukan container, yang berakibat pada terganggunya kelancaran operasional kapal. Penelitian ini merekomendasikan penerapan inspeksi visual berkala, penggantian rubber seal, pelapisan ulang cat anti-korosi, serta pengawasan terhadap distribusi beban muatan sebagai upaya dalam menjaga fungsi tutup palka dan keselamatan konstruksi ruang muat kapal. Kata kunci: tutup palka, ruang muat,kontruksi kapal

Abstract

This study aims to develop an effective seafarer competency improvement model in reducing turnover rates in the Indonesian maritime industry. The research method used is a mixed-method with a quantitative and qualitative descriptive approach. Data collection was carried out through questionnaires, interviews, and documentation studies of 150 seafarers from five national shipping companies. The Technology Readiness Level (TRL) of the proposed model was evaluated at TRL 7, indicating that this model has been tested in a limited operational environment with adequate results. The results showed that 65% of seafarers felt they did not receive adequate competency-based training, while 48% of them indicated a desire to change jobs shortly. The competency improvement model, designed based on digital technology and simulation-based training, succeeded in increasing the average competency score of seafarers from 68% to 85% within six months. In addition, the turnover rate of the company that became the pilot project for this model decreased from 22% to 14%. This study offers a state-of-the-art in the form of an integration of competency-based approaches with digital technology, different from previous studies that focused on conventional interventions. The novelty of this study lies in the use of a digital-based model that combines continuous evaluation and adaptive training programs that are tailored to the needs of individual seafarers. This model is expected to be a strategic solution to increase seafarer retention in the maritime industry while strengthening the competitiveness of the Indonesian workforce in the international market.

Abstract

Sharia Securities-based crowdfunding (Sharia SBC) has emerged as a novel financial innovation that integrates Islamic principles with financial technology, expanding investment access in Indonesia. However, this development has also created significant regulatory gaps and legal risks related to data protection, Sharia compliance, information asymmetry, and weak dispute resolution mechanisms. This study examines the adequacy of Indonesia’s dual regulatory model, the Financial Services Authority (OJK) and the National Sharia Council (DSN-MUI), in protecting investors and ensuring Sharia compliance in SBC. Using normative legal methods combined with comparative and policy-oriented approaches, the study identifies the lack of binding force in DSN-MUI fatwas, the limited role of the Sharia Supervisory Board, and weak enforcement of data security and disclosure standards. Comparative studies from Malaysia and Bahrain suggest that integrating Sharia audits and a centralized dispute resolution mechanism can strengthen legal certainty. These findings underscore the need for regulatory reforms to render DSN-MUI fatwas legally binding, establish a Sharia arbitration body, and mandate annual Sharia compliance audits for SBC operators. These recommendations aim to improve legal certainty, investor protection, and the integrity of Shariabased financial technology in Indonesia.

Abstract

This study examines the association between Bridge Simulator training, seafarers’ self-awareness, and emergency decision-making performance. A quantitative correlational design was employed involving 105 active seafarers who had participated in certified bridge simulator training. Data were collected using a structured questionnaire measuring perceived training quality, self-awareness, and emergency decision-making performance. Spearman’s rho correlation analysis revealed a strong positive association between Bridge Simulator training and self-awareness (ρ = 0.764), as well as between Bridge Simulator training and emergency decision-making performance (ρ = 0.744). These findings indicate that higher perceived quality of simulator training is associated with higher levels of self-awareness and decision-making performance in emergency contexts. The study contributes empirical evidence on the psychological and cognitive dimensions associated with simulator-based maritime training and highlights implications for maritime education and safety training.
