The purpose of this research is to examine and analyze the validity of scientific crime investigation as evidence in the process of proving murder cases and what are the advantages and disadvantages of using the scientific crime investigation method in crime scene processing carried out by forensic laboratories. Then the method used in this research is the normative legal research method. The results of the study show that the scientific crime investigation method, which is expressed in concrete form through forensic laboratory examinations and information from police forensic experts, is the central point. In connecting the relationship between the perpetrator, victim and evidence with the crime scene, the construction of evidence for a criminal act becomes stronger and can give confidence to the judge in deciding a case fairly and in accordance with the actual facts. In the case of the crime of murder with poison, the statements of the witnesses and the statements of the two defendants were linked and interconnected with each other after the scientific crime investigation method was applied; The advantages and disadvantages of using scientific crime investigation methods in crime scene processing carried out by forensic laboratories include. The advantages and disadvantages of using scientific crime investigation methods in crime scene processing carried out by forensic laboratories include: (1). The advantage of implementing scientific crime investigation is that uncovering cases using old methods full of violence, intervention, etc. has been abandoned. (2) Fast, precise and accurate inspection supported by special tools that have been internationally standardized, (3) Minimizing errors made before SCI implementation (manual patterns replaced with digital patterns). Meanwhile, the weaknesses are: Internal side of the SatKer (Work Unit): the number of human resources who supervise and understand the use of Special Tools (Alsus) is limited, the special equipment, both primary and secondary, is expensive. If we look at the human resources that this country has, it should be enough to assist the Forensic Laboratory team in supervision and are people who understand the special tools that support the performance of the Forensic Laboratory. Apart from that, the government should be more respectful of the procurement of these special tools, even though not everyone has to always use these special tools. However, these tools are very useful for the smooth running of investigations and/or investigations. Because the resulting examination data is much more detailed and accurate.

This Industrial Internship (Prakerin) was conducted at PT. Perkebunan Nusantara IV Regional II, Plantation Unit, and Adolina Palm Oil Mill (PKS). It focused on analyzing the effect of crude palm oil (CPO) thickness in the Continuous Settling Tank (CST) on CPO impurity levels. The issue raised was the persistent variation in impurity levels in CPO, which is suspected to be influenced by the thickness of the oil layer during the collection process. This study aimed to determine the relationship between CPO thickness in the CST and the resulting impurity levels. The method used was CPO sampling at several oil thicknesses (33–46 cm), followed by laboratory impurity analysis using Gooch Crucible Filter filtration and gravimetric calculations. Data were obtained during the period July 4–11, 2025. The results showed that at a thickness of 45–46 cm, the lowest impurity content was 0.01%, while at a thickness of 33 cm, the highest impurity content was 0.04%. At a thickness of 35 cm, the impurity content was 0.03%, and at a thickness of 40 cm, it was 0.02%. This indicates an inverse relationship between CPO layer thickness and impurity content, where the thicker the oil layer, the lower the impurity content. Therefore, it can be concluded that maintaining a minimum oil thickness in the CST tank of ±40 cm is a crucial step in maintaining CPO quality and ensuring it meets industry standards.
