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.

A number of studies related to the politics of criminal law in the Dfrat wetboek van straf recht (RKUHP) have increasingly tightened the state's grip on matters that de facto can be resolved by other types of law such as religion, decency and manners that already exist in society. At that point, efforts to think about the objectives of environmental and natural resource crimes in the RKUHP feel increasingly complicated to think about because this draft seems to be complicated and between various things, can consist of understandings, concepts, paradigms, which are related to and conflict with each other. another. This article uses normative legal research, the author obtains data from library materials which are usually called secondary data, which includes primary, secondary and tertiary legal materials. The author then studies and explores these legal materials and quotes theories or concepts from a number of literature, including books, journals, papers, newspapers or other written works related to the problem under study. This article explains that the position of the RKUHP regarding laws in the field of environment and natural resources is not yet clear, because the RKUHP does not expressly state its position regarding other laws. UU no. 10 of 2004 concerning the Preparation of Legislative Regulations also does not help provide answers because it does not recognize the general and specific designations or categories of laws as well as the requirements to fulfill these categories and this RKUHP is only able to absorb the criminal articles of each law. sectoral law, apart from other parts contained in the law. This means that the codification of this model consciously releases the historical and logical ties between the parts contained in each law.

The purpose of this article is to find out how to change environmental legal policy into environmental law into the Job Creation Law and to find out the appropriate efforts to address changes in environmental legal policy from the environmental protection perspective of the Job Creation Law. The research method presented in this article uses a normative legal approach, namely descriptive analysis. The results of the study in the article show that the concept of environmental law has become a legal policy that activates various instruments that regulate environmental problems in Indonesia, both regulatory and planning instruments. Finally, the aim of environmental legal policy is to ensure the implementation of sustainability in Indonesia from an environmental perspective. Efforts that must be made to address changes in environmental legal policy from the environmental protection perspective of the Job Creation Law are: 1) Simplification of permits; 2) Strict responsibility and 3);Restrictions on environmental rights. These three things cannot be taken lightly, so as not to have the worst impact on the quality of the environment. The Job Creation Law and its derivatives already existed until legal action was taken to revoke them. This is an important consideration where the Government must continue to develop good faith partnerships with the community to implement the Work and its consequential provisions.
