Abstract

PT. Perintis Makmur Indonesia (PMKI) is a smelting company that plays an important role in workforce absorption in the Morowali area. In particular, the mechanical department, consisting of 18 employees, requires an upgrade in pipe welding skills using the SMAW welding method. This is due to the fact that the mechanics are currently only capable of performing plate-to-plate welding, whereas they are required to have pipe-to-pipe welding skills to support their work. To enhance its employees' competencies, particularly in pipe welding, PT PMKI collaborated with the Morowali Metal Industry Polytechnic to organize a Shielded Metal Arc Welding (SMAW) training program for its employees. The primary goal of this training was to improve the employees' skills in performing pipe welding safely and efficiently. The training methods included lectures, discussions, and hands-on practice in the workshop, along with evaluations through pre-tests and post-tests. A total of 18 mechanics participated in this fiveday training. The materials covered welding safety, SMAW techniques, and defect handling in welding. The results showed a significant increase in participants' understanding and skills. The initial understanding level, as measured by the pretest, was only 19.8%. After the training, participants' understanding increased to 93.2%, as indicated by the post-test results. This training successfully improved the employees' pipe welding competencies, which are crucial for supporting the company’s operations.

Abstract

Hemangioma is a vascular anomaly that is benign and generally occurs in children. ISVVA 2018 classifies vascular anomalies into two categories, namely vascular malformations and vascular tumors (hemangioma). The prevalence of hemangioma is higher in low birth weight babies, premature babies, and girls. Several theories suggest that hemangiomas are caused by vasculogenesis and angiogenesis or an imbalance between angiogenic and antiangiogenic factors. Hemangiomas grow through a proliferation phase, involution phase, and post-involution phase. Hemangioma classification is based on the depth of the lesion, time of appearance of the lesion, distribution of the lesion, and its relationship to syndrome complication.. Diagnosis of hemangioma is based on anamnesis, physical examination, and supporting examinations which include USG, MRI, and CT-Scan. Hemangiomas that lead to complications should require immediate treatment. Hemangioma treatment can be done with topical therapy, systemic therapy (propranolol, corticosteroids, β-blockers, vincristine, rapamycin), laser therapy (PDL, diode, Nd: YAG, argon, KTP, CO2, IPL), and other treatments consisting of from surgical and non-surgical procedures (bleomycin injection).

Abstract

Wounds are skin disorders caused by pathological processes. Abrasion wounds are a type of acute injury. One of the contributing factors is traffic accidents. More than 1.2 million people died as a result of traffic accidents, while 20-50 million others suffered injuries. Choosing the proper dressing can determine wound healing. This case study aims to determine the effectiveness of silicone wound dressing in the healing process of contaminated abrasion wounds. Contaminated abrasion wounds are contaminated by dirty materials, which potentially cause infection. This case report describes four patients, Mrs. W, Mrs. K, Mr. Y, and Mr. M., who suffered abrasions on the face. Their wounds were cleaned in the operating room under general anesthesia. A silicone wound dressing is applied as the primary dressing. The secondary dressing depends on the amount of the exudate. On the 3rd day after the surgery, the wounds looked dry, so they were cleaned and reapplied with the silicone dressing. On the 7th day, after applying silicone wound dressing, the wound had epithelialized. Silicone wound dressing is a modern type of dressing that is effective for acute wounds as it provides a barrier against external contamination. Our sample shows that wound are abrasion contaminated. The result of silicone wound dressings applied was shown accelerate the wound healing process. Modern dressings accelerate wound healing 20% to 40% faster than conventional dressings, such as gauze, tulle, or gauze.

Abstract

Bearing failure is one of the main causes of operational disruptions in mechanical systems due to the lack of continuous condition monitoring. Early detection of vibration and temperature increases is essential to prevent downtime and reduce maintenance costs. This study aims to design and develop a bearing condition monitoring prototype based on the Internet of Things (IoT) using the Research and Development (R&D) approach. The system employs an Arduino Uno and NodeMCU ESP8266 as the main controllers, a piezoelectric sensor to detect vibration, and an MLX90614 infrared sensor to measure the bearing surface temperature. The measured data are transmitted in real time to the ThingSpeak platform for remote visualization and analysis. Experimental testing over three hours showed an average vibration of 7.25 Hz and an average temperature of 35.87 °C, where the condition indicators on the LED and LCD operated according to the predefined thresholds. The system successfully provided early warnings of potential bearing failure through continuous parameter monitoring. The novelty of this research lies in the integration of low-cost multi-sensor technology with the ThingSpeak platform for real-time, end-to-end bearing condition monitoring, supporting the concept of predictive maintenance.
