Abstract

The purpose of this study is to provide a design for inventory management at the Teaching Factory Manufacture Electronics (TFME) Batam State Polytechnic with a Project-Based Learning (PBL) review. In addition, this study also applies inventory recording in the second basic financial accounting course (AKD2). This study uses qualitative methods with exploratory and descriptive research classifications. The method of collecting data in this research is by direct interviews with the informants. Researchers also made direct observations in the field and collected the necessary data from the main data sources. The results of this study indicate the importance of managing inventory in TFME, one way of managing inventory is by making an inventory card. The inventory card design that has been made is expected to be able to control inventory and the inventory card is designed to be very easy to use, for the use of an inventory card, consistency is needed from all parties involved

Abstract

Heat Treatment is a process of heating a material (metal) with a certain temperature and then cooling it using certain media (for example: oil, water, and salt water) with a specified cooling speed. This research used a quenching and tempering heat treatment process on API 5L carbon steel pipe with a diameter of 16 inches (406.4 mm) and a pipe thickness of 1,437 inches (36.5 mm), which previously the carbon steel pipe had an overlay welding process on the inside using UNS N06625 filler metal with protective gas of Argon 99.999% to reduce the corrosion rate along the bending process to become Clad Bend Pipe. The purpose of this study is to find out any effects of heat treatment (Quenching and Tempering) to increase the value of the tensile test results on clad bend pipes.

Abstract

Personel Protective Equipment (PPE), as prevention to curb COVID-19 transmission which mainly via droplet, is a mandatory protocol as rising COVID-19 confirmed case. Face shield can protect face from droplet exposure. Besides health care professionals, pregnant women and newborn infants are susceptible population to exposure of SARS-CoV-2. Infant under two years is not recommended to use face mask due to breahing difficulty which can lead to mortality. Therefore, face shield is recommended for infant to give protection from virus transmission. As part of community service, Politeknik Negeri Batam produces Non Medical Infant Face Shield for infant and toddler to curb COVID-19 transmission. The program aims at community health centers (Puskesmas) of Batu Aji, Tanjung Uncang, Sekupang, and Kampong Jabi Nongsa. These partners value highly the community service program in terms of simplicity, clear working instruction, comfortability, recurring sterilization, and product quality. Moreover, high demand of face shield in Puskesmas that use face shield more than three times a day, indicates benefit of the community service in providing PPE for medical treatment at Puskesmas

Abstract

High residual stress can occur in stainless steel and carbon steel weld joints due to difference of thermal expansion coefficients. Corrosion-resistant and mechanical properties of weld joint is affected by stainless steel sensitization, resulted by chromium carbide precipitation, and carbon diffusion on heat-affected zone. This study is conducted to investigate post-weld heat treatment effects of stainless steel 316 and AISI 1018 weld joint with 309L filler metal. As the post-weld heat treatment temperature rises between 400 and 700°C, the hardness value decreases. Observed microstructure of heat-affected zone shows dominance of ferrite phase which experiencing grain growth.

Abstract

Corrosion is a problem that always occurs in metals in their application to the environment. Although there are already several other substitute materials such as polymers and composites, the use of metals is still very much needed and plays an important role, especially in the oil and gas fabrication industry. Corrosion cannot be avoided but can be minimized because of the nature of the metal that will return to its origin. Metals used in the oil and gas fabrication industry require a material test against stress factors and the environment. The SSCC (Sulphide Stress Corrosion Cracking) test based on NACE TM0316 is a test of material resistance to stress and acidic environments. In this SSCC test, the method used is Four-Point Bending, which means that there are four roller jigs to bend the specimen. The specimens used are API 5L X65 pipe welded joint specimens and ASTM A694 flange. The welding process on this specimen uses the GTAW (Gas Tungsten Arc Welding) process. The specimens tested have several stages, starting from the preparation of the machined material, cleaning, then bending to soaking in an acidic liquid. This aims to determine the indications that appear on the surface of the specimen in the form of cracks in both the weld and the base metal. The test used three specimens with different IPRR welding processes. Specimens 1 and 3 are accepted specimens, while specimen 2 is rejected specimens based on the SSCC DNV Test Procedure, where the acceptance criteria from the MPI results are acceptable if the indication is less than 1 mm in length.

Abstract

NDT means testing without damaging the material or specimen. One of the NDT equipment that can be used to measure the thickness of the hull plate is the Ultrasonic Thickness Gauge (UTG). This tool uses sound waves that are reflected and received by the probe and converted to numerical data, the number is used to see the thickness of the plate material. The research purpose is identifying the thickness of tanker Tyche hull plate by Ultrasonic Thickness Gauge (UTG). Based on data from the Tyche hull shell opening table on the portside and sideboard the smallest test results are 9.7 mm. These results are still included in the tolerance because if the initial plate thickness is calculated from 12 mm – 2.4 mm, then the minimum acceptable thickness is 9.6 mm. If it is found that the plate thickness is below 9.6 mm based on the standards from the Indonesian Classification Bureau (BKI), the plate will be declared NG (Not Good) and the replating process will be carried out. Based on the test table, no UTG results were found which were below the standard plate thickness that had been set. Therefore, the Tyche tanker with the IMO code 8794891 is still feasible to operating and there is no need for a partial or complete replating process.
