Abstract

Kenari (Canarium indicum L) belongs to the Burseraceae family and is one of the endemic fruits in Indonesia, especially Maluku. Walnuts have a tough shell that encloses the flesh, to get the flesh without damaging it careful effort is needed. This study investigated the strength of walnut shells through mechanical testing to determine the amount of impact force needed to break the walnut shell. The mechanical test carried out is a compression test and impact test. The values of these tests assist in determining, measuring, and analyzing the minimum and maximum force loads required to crack a walnut shell. Tests were carried out on walnut shells from 6 different villages on Ambon Island and Saparua Island. The impact test where the highest impact absorption energy value was found in walnut shells from Booi Village, namely 23.18 J/mm2, and the lowest in walnut shells from Morela Village, 22.40 J/mm2. In the compression test where the lowest value was found in walnut shells from Morela village with a value of 3.61 MPa while the highest value was found in walnut shells from Booi village, namely 5.24 MPa. Whereas the minimum compressive force is 16.22 kgf/mm2 and the maximum compressive force is 17.61 kgf/mm2.

Abstract

AbstractThis study is entitled "Corrosion Rate Analysis of Remaining Life Storage Tank T03-300 KL at PLTD Poka Using the Risk Based Inspection (RBI) Method". The purpose of this study is to evaluate the corrosion rate and residual life of the T03-300 KL storage tank used at PLTD Poka, as well as to provide recommendations related to appropriate inspection strategies based on risk analysis. The method used in this study is Risk Based Inspection (RBI), which allows the determination of the probability of failure (PoF) and the consequences of failure (CoF) of the storage tank. The data collected includes primary data through observation, measurement, and direct inspection of tanks, as well as secondary data from relevant literature.Keyword : Corrosion Rate, Remaining Life, Storage Tank Risk Based Inspection (RBI), Probability of Failure (PoF), Consequence of Failure (CoF)

Abstract

The oil pipeline network is a critical infrastructure that plays a vital role in the oil and gas industry. However, one of the significant challenges faced by this pipeline system is corrosion. Corrosion is a chemical process that leads to the deterioration of metal quality due to electrochemical reactions with the environment. Corrosion in oil pipelines not only reduces the wall thickness but can also result in leaks, structural damage, and even accidents that negatively impact human safety and the environment.The objective of this research is to analyze the corrosion rate in the elbow joints of oil pipelines at PT PLN (Persero) ULPTD Poka. This study employs a quantitative method involving two variables. The independent variable is the elbow type, specifically the 90° elbow, while the dependent variables are the corrosion rate calculations and the remaining service life (RSL) of the elbow pipes.The results indicate that the corrosion rate varies at each measurement point on the elbow joints. The RSL calculations show significant variation based on the thickness of the pipe wall at each elbow. The highest RSL values were found in elbows 3, 4, 5, and 8, with a remaining service life of up to 49.5 years. Conversely, elbow 1 had the lowest RSL at 38 years. The higher RSL in some elbows suggests that despite experiencing corrosion, the remaining thickness is still sufficient to support the pipeline's function for a longer duration. Recommendations include the need for intensive maintenance on the oil pipeline elbow joints, especially on segments above ground and near corrosive sources.
