The high rate of occupational accidents globally and nationally demands the strengthening of Occupational Health and Safety (OHS) management systems, particularly in the high-risk industrial sectors. The study aims to analyze the implementation of safety induction at PT X and develop audiovisual educational media as a solution to improve occupational safety understanding. The research method employed is descriptive qualitative, with data collection techniques including field observations, in-depth interviews, and review of corporate documents, Problem prioritization was determined using the Urgency, Seriousness, and Growth (USG) method, while root cause analysis was conducted using a Fishbone diagram. Research findings indicate that the current oral delivery method for safety induction is ineffective, as evidenced by 13% of participants needing to retake the comprehension test. As an intervention, “POWER SAFE” video media was developed, which, based on the Methodology, Effectiveness, Efficiency, and Relevance (MEER) analysis, proved to have the highest effectiveness and relevance in delivering standardized safety information. The implications of study emphasize that the use of structured digital media is a strategic step to minimize gaps in understanding and strengthen the safety culture within high-risk work environments.

The implementation of Occupational Safety and Health (OSH) is a crucial aspect in construction projects to minimize workplace accidents and improve labor productivity. This internship report aims to evaluate the implementation of the OSH system at PT. X on the RSPTN Universitas X Project. The methods used include field observations, interviews with related personnel, and documentation review. The results indicate that OSH implementation has been carried out through the provision of personal protective equipment (PPE), safety induction programs, installation of safety signs, and routine supervision. However, several violations in PPE usage were still observed. Consistent and continuous OSH implementation is necessary to achieve the zero accident target in the project environment.

Three-phase induction motors are essential components in industrial cooling systems that require reliable overcurrent protection to maintain operational continuity and prevent equipment damage. In the Cooling Tower Pump panel at PT DongJin Indonesia, a limitation was identified where the terminal of the Electronic Overcurrent Relay (EOCR) could not accommodate the 50 mm² power cable, preventing direct current measurement. This study aims to analyze the effectiveness of integrating a 200:5 A Current Transformer (CT) with the EOCR as an adaptive protection solution that is both safe and efficient. The research employs a case study approach through field observation, motor current measurement using a Fluke 303 Clamp Meter, and descriptive analysis of the recorded data. The results indicate that the three motors operate under stable load conditions, with current values ranging from 236.7 A to 275.7 A, while the secondary current detected by the EOCR ranges from 3.7 A to 3.9 A, consistent with the CT transformation ratio. During the starting phase, the current surged to 600.4 A without causing false tripping, demonstrating that the EOCR effectively distinguishes temporary inrush current from actual fault conditions. Therefore, the integration of CT–EOCR is proven to enhance measurement safety, maintain motor operational stability, and support efficient system maintenance in industrial environments.

Eleutherine bulbosa (Mill.) and Allium cepa L. (including garlic and onion peel) are medicinal plants that have long been traditionally used to treat cancer, diabetes, hypertension, infectious diseases, and inflammation. Recent scientific studies emphasize the importance of extract standardization to ensure consistent quality, safety, and efficacy. Standardization includes specific parameters—such as organoleptic identification, water- and ethanol-soluble extract values, phytochemical profiles, and determination of marker compounds—and nonspecific parameters such as moisture content, loss on drying, total ash, and acid-insoluble ash. Ethanol extract of E. bulbosa showed moisture and drying loss values below 10%, total flavonoid content of around 1.2%, and positive phytochemical tests for alkaloids, flavonoids, saponins, and quinones. Onion peel extract contains a high flavonoid content (7.84 mg QE/g) with moderate antioxidant capacity (DPPH IC₅₀ 152.65 µg/mL), while fermented garlic (black garlic) contains more than 12% polyphenols and more than 2% flavonoids, as well as a high level of S-allyl-L-cysteine (SAC) as a stable bioactive compound. The pharmacological activities of these standardized extracts include strong antioxidant effects, α-glucosidase inhibition for antidiabetic activity, induction of apoptosis and anti-angiogenesis as anticancer potential, membrane disruption and enzyme inhibition for antimicrobial activity, as well as COX/LOX modulation for anti-inflammatory effects. These activities are directly correlated with the secondary metabolite composition of each material. With their phytochemical richness and diverse biological activities, E. bulbosa and A. cepa have great potential as raw materials for standardized herbal products. Further in vivo studies and clinical trials are needed to validate their therapeutic efficacy and to support the development of evidence-based phytopharmaceuticals.

This study aims to comparatively analyze the effects of two types of inhalation anesthetics, ether and chloroform, on Wistar rats, focusing on three main parameters: induction time, duration of anesthesia, and side effects. Selecting the appropriate anesthetic method is crucial in animal studies to ensure animal welfare and the validity of the results. Twenty male Wistar rats, with an average body weight of 200–250 grams and 10–12 weeks of age, were randomly divided into two treatment groups of 10 rats each. The first group was anesthetized using ether, while the second group was anesthetized using chloroform, with doses adjusted to achieve adequate levels of anesthesia. Measurements were made of the induction time, which is the interval from the start of anesthetic exposure until the loss of the pedal reflex; the duration of anesthesia, which is the length of time until the rat regains consciousness; and clinical observations of any side effects that appear, both during and after anesthesia. The results showed that the ether group had a relatively longer induction time than the chloroform group. However, ether provided a longer and more stable duration of anesthesia, with a better recovery rate. In contrast, chloroform produced a shorter induction time but was accompanied by a shorter duration of anesthesia and a higher risk of side effects, particularly liver dysfunction and respiratory depression. These findings reinforce previous reports that chloroform has significant potential toxicity, and its use in animal research should be limited. Based on these results, ether is recommended as a relatively safe inhalation anesthetic option for laboratory procedures in Wistar rats, although its use still requires strict supervision and appropriate handling procedures to ensure the safety of both researchers and experimental animals.

Research conducted at CV Multi Teknik Perkasa Palembang indicates that the total installed power for various panels is 18,448 watts, consisting of 448 watts for lighting panels, 5100 watts for induction motor power panels, 9000 watts for cooling panels, and 3900 watts for lamp and socket panels. Further analysis reveals that the power consumption does not exceed the available power. Therefore, the electrical installation at CV Multi Teknik Perkasa Palembang is in good and safe condition for use.
