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.

The Kediri Airport development project encountered challenges related to underground ducting work. The design of Kediri Airport adheres to international standards, which led to the use of materials not readily available in Indonesia, specifically pipes and duct spacers. Duct spacers are tools used to arrange ducting pipes according to their formation and prevent them from floating during concrete pouring due to buoyancy. The SKEP/114/VI/2002 serves as a reference for underground cable installation, involving direct burial of cables at a depth of 70 cm, covered with a 5 cm layer of sand above the cable surface. These two approaches significantly differ, necessitating problem-solving solutions. To address this issue, research was conducted to find suitable duct spacers in Indonesia. Two alternative materials were considered: PVC and lightweight hollow steel. The study compared costs and time associated with these materials. PVC duct spacers would be imported and be fabricated in Indonesia, while hollow steel duct spacers would be fabricated on-site. The research focused on three aspects: ducting work methods, duct spacer design, and cost-time analysis. Given tight installation spaces and busy schedules, duct spacers needed to be compact, simple, and adaptable to various pipe formations. The design for hollow steel duct spacers aimed for simplicity to reduce on-site construction work. However, care was taken to avoid potential injuries from exposed bolts on the hollow steel frame. The PVC duct spacer design utilized Polytam PF 1000 material, with a nominal shear strength of 399 kg and a nominal moment of 266 kg·cm—sufficient to withstand saturated soil loads up to 162 cm but not vehicular loads. Analyzing procurement time, PVC duct spacers from Indonesian manufacturers were the quickest, taking only 56 days due to no port clearance delays. The fastest completion time for the project was achieved using PVC duct spacers, taking 122 seconds—three times faster than hollow steel duct spacers. While lightweight steel was the most cost-effective option for on-site procurement, combining cost and time analysis favored PVC duct spacers. The minimal cost difference allowed for accelerated production, minimizing the risk of delays    

The Sea and Coast Guard Base (PLP) plays a vital role in maintaining maritime security and safety in Indonesia, especially in strategic waters such as the Riau Islands. However, the implementation of the PLP's authority in carrying out its duties at the Tanjung Uban Class II PLP Base has not run optimally. This study aims to analyze the authority of the PLP from a juridical and sociological perspective, as well as identify the obstacles faced and provide recommendations to overcome them. The research methods used are normative juridical and empirical sociology. The normative juridical method is used to analyze various laws and regulations that are the legal basis for the authority of the PLP, such as Law Number 17 of 2008 concerning Shipping, Regulation of the Minister of Transportation of the Republic of Indonesia Number PM 119 of 2021 concerning the Organization and Work Procedures of Marine and Coast Guard Bases, Decree of the Director General of Hubla Number 13/VIII/DV-05 of 2005 concerning the Working Area of Marine and Coast Guard Bases and the Decree of the Director General of Sea Transportation Number KP.867/DJPL/2020 concerning the Patrol of the Marine and Coast Guard Unit of the Directorate General of Sea Transportation. Empirical sociological methods are used to collect data through interviews and direct observations in the field to understand the implementation of PLP authority and the obstacles faced. The results of the study show that limited human resources and equipment, lack of coordination between agencies, inadequate infrastructure, and complex bureaucracy are the main obstacles in the implementation of PLP authority in the Tanjung Uban Class II PLP Base. In addition, the low legal awareness among the maritime community is also a significant challenge. Based on these findings, this study provides several suggestions, including increasing recruitment and training of personnel, procurement and maintenance of patrol boats and supporting equipment, the formation of an inter-agency coordination team, the construction of adequate port facilities, and socialization and education to increase public legal awareness. This research is expected to contribute to strengthening policies and strategies for the implementation of PLP authority, so as to be able to increase effectiveness and efficiency in maintaining maritime security and safety in Indonesian waters.

The product life cycle was first used in US Department of Defense military matters, where it applied mainly to DoD procurement of military equipment. Its use has expanded by companies operating in various sectors, such as building and construction, machinery and equipment manufacturing, and other industries that require high costs, and the life cycle of their products is relatively long and has clear stages, as the complete product life cycle mainly covers the costs of research, experimentation, acquisition, maintenance, transportation, and storage, and that the essence LCC is not only the running cost, but also the cost related to the product.The research at Nasr General Company for Mechanical Industries aims to shed light on two main tools of contemporary cost management that work to calculate the cost of the product over the product life cycle and make improvements to it continuously according to the continuous improvement technique. Thus, they work appropriately to reduce product costs and the costs are calculated according to The accounting system prepared in the company under investigation..

Housing is a collection of houses as part of settlements, both urban and rural, which are equipped with public infrastructure, facilities and utilities as a result of efforts to provide livable houses. If you look at the definition of housing, you can see that infrastructure, facilities and public utilities are requirements that must be completed in housing. In fact, when the housing is still under construction, housing marketing through a preliminary sale and purchase agreement system can only be carried out after there is certainty about several things, one of which is the availability of infrastructure, facilities and public utilities. Quantitative data from interview results is described in a frequency table qualitatively and descriptively. The data that has been obtained through research activities is analyzed qualitatively. Qualitative analysis is used to describe the data obtained, both primary data and secondary data, which is then followed by interpretation and conclusions. Implementation of the procurement of public facilities and social facilities is a mandatory requirement that must be provided by the developer/developer to obtain a building construction permit (IMB) from the Spatial Planning and Building Service. Where housing is a collection of houses as part of settlements, both urban and rural, which are equipped with infrastructure, facilities and public utilities as a result of efforts to provide livable houses. The development of housing infrastructure, facilities and public utilities is carried out by the Government, regional governments and/or every person. So the responsibility of the Surabaya City Regional Government for social facilities and public facilities in residential and residential areas is to carry out management, namely, by utilizing these facilities according to their intended use and by carrying out maintenance so that these facilities can be used optimally by residents.

This Journal discusses the juridical analysis of compensation in land acquisition due to the construction of dam reservoirs in Bolaang Mongondow Regency. Procurement of land for the benefit of development is often collided with the stages that take time, whereas the land is needed immediately. The rules for the implementation of land acquisition state that for the acquisition of land with an area of not more than 1 hectare, it can be carried out directly by agencies that require land with the right parties. One of the problems that arise in the procurement of land is the provision of compensation to the owner of the land that will be used for construction. Article 27 of Law No. 2 of 2012 on Land Acquisition for Development states that land acquisition must include an assessment of compensation and the provision of appropriate and fair compensation to the entitled party and Article 1365 of the Civil Code. This study uses empirical research methods with a case approach. The purpose of this study was to analyze the implementation of compensation in land acquisition due to the construction of dam reservoirs and the inhibiting factors in the provision of compensation. The legal basis is a reference in the procurement of land in Indonesia. In practice, however, there are some obstacles to the award of damages. In the case of the construction of a reservoir dam, the government and companies have promised compensation to the public since 2013. However, as of 2019, the land has not been compensated to the community. In 2022, the land was flooded and could no longer be managed by the community, so the case had to be resolved through litigation. It is hoped that the results of this study can provide a deeper understanding of this problem and become a reference in improving the effectiveness and efficiency of land acquisition in Indonesia.

The factors that can affect the delay in the completion of road construction projects within the government of the Depok City Public Works Agency which are obtained from the analysis are poor material procurement; insufficient human resources; less than optimal contract management; procurement of construction equipment that is not managed; there is a request for changes to the work being done; financial problems; poor construction work monitoring and control; negative intervention from the community; slow decision making by the owner and changes in field conditions (weather, accidents, etc.). Based on the relative index method, the most influential factors are: 1. Unmanaged procurement of construction equipment 2. Changes in field conditions. Meanwhile, in the factor analysis method, it is obtained: Inadequate human resources (in the form of quantity and quality) less incompatible with the existing location of activities CCO (Contract Change Order) often occurs.

The model developed illustrates that the rewards system, digitalization and audio-visual campaigns have a positive influence on worker safety motivation and indirectly influence worker safety behavior through worker safety motivation which acts as a mediating variable. Meanwhile, work safety motivation has a positive effect on work safety behavior.    

As Time And Human Civilization Progress, The Construction Industry Is Also Developing Rapidly, Starting From Advances In Technology Used To Increasing Competitors, Both Foreign Competitors And Local Competitors. The Application Of Supply Chain In The Construction Industry Is Believed To Be One Of The Strategic Efforts To Increase The Competitiveness And Performance Of A Construction Company. In This Research, An Analysis Of The Application Of Supply Chain Management (SCM) Will Be Carried Out In The Wadung Asri Market Drainage Channel Normalization Project. This Research Aims To Find Out Whether Contractors Have Implemented The Supply Chain Management (SCM) Concept In Their Material Procurement Process. The Research Results Show That In The Project Material Procurement Process, The Contractor Has Not Implemented The Supply Chain Management (SCM) Concept Significantly. This Can Be Seen From Decisions In Selecting Suppliers Which Are Only Based On The History Of Cooperation Without Considering Other Factors. Apart From That, There Were Delays In The Arrival Of Materials Which Resulted In Project Work Being Delayed From The Initial Plan. Therefore, It Is Necessary To Improve The Goods Procurement System That Has Been Running So Far By Implementing The Supply Chain Management Concept.
