With the potential for various economic impacts in the Holtekamp Coastal Area due to the construction of the Youtefa Bridge, it is necessary to analyze the multiplier effects in the Holtekamp Coastal Area. In this study, the researcher used a combination of qualitative and quantitative research methods called a mixed research method. In this method, the researcher simultaneously collects qualitative and quantitative data sourced from questionnaires, observations, and document studies. The data analysis methods used in this study include the Likert Scale, descriptive analysis, and multiplier effect analysis. The results of this study indicate that the overall perception of the community, both business actors, local workers, and tourists, towards every tourism condition in Holtekamp Beach is ranked Moderate to Very Good. However, several aspects still need to be considered, including street lighting, less than optimal, and the availability of souvenirs, which still needs to be improved. Overall, the Holtekamp Beach tourist area has had a considerable impact, which can be seen from the results of the multiplier value calculations, which show a value greater than one (>1), including the Keynesian Income Multiplier value of 1.51, the Ratio Income Multiplier type I value of 1.66 and the Ratio Income Multiplier type II value of 1.80.

Law is defined as a rule or norm that must be followed by humans. To ensure the implementation of law in Indonesia, various legal products are needed, especially laws that regulate community activities. Firearms abbreviated as Senpi are weapons that release one or more projectiles that are propelled at high speed by gas produced by the combustion of a propellant (projectile). The problem of ownership to misuse of firearms is something that is very dangerous and high risk, resulting in fatalities in society, the increasing number of cases in recent years in Indonesia shows the importance of the seriousness of law enforcement in responding to this problem. Misuse of Illegal Firearms Ownership is regulated in Emergency Law Number 12 of 1951 concerning the amendment of the "Ordonnantie Tijdelijke Bijzondere Strafbepalinge" (STBL. 1948 No. 17) and the Former Republic of Indonesia Law Number 8 of 1948 stating that anyone who without the right to enter Indonesia makes, receives, tries to obtain, submits or tries to submit, controls, carries, has a stock of it or has in his possession, stores, transports, hides, uses, or removes from Indonesia a firearm, ammunition or explosive material, is punished with the death penalty or life imprisonment or a temporary prison sentence of up to twenty years. Police Regulation Number 1 of 2022 dated January 28, 2022 concerning licensing, supervision and control of Polri firearms, non-organic TNI-Polri firearms and security equipment classified as firearms, namely non-TNI-Polri firearms with types of non-TNI-Polri firearms including live ammunition firearms, rubber bullets, and gas bullets from the Polri. The process from ordering to handover of goods to the owner, both the legality of documents and physical control (ballistic tests) are under the supervision of the Polri. The circulation of illegal firearms among the Indonesian people requires law enforcement, especially the Police, to be more active and take early prevention measures against those who own, make, and supply illegal firearms that threaten the lives of the community due to the impacts caused by illegal firearm ownership. The case of firearm ownership against the defendant SULIS NURFITO, Ponorogo, 34 years old, Male, Jln. Swadaya Kel. Bukit Batrem District. Dumai Timur Province. Riau, Islam, Construction Workers with Decision NUMBER 2157/Pid.Sus/2017/PN Mdn sentenced to 2 (two) years and 3 (three) months in prison, making the public's perspective on the world of justice in Indonesia far from the public's expectations considering the threat of punishment for the Article applied with the threat of 20 Years in Prison with the verdict given by the judge of 2 (two) years and 3 (three) months shows that law enforcement is far from the public's expectations and does not have a deterrent effect on the defendant and other users of illegal firearms who have not been arrested by the Police.

The problems that occurred at MAN 1 Gorontalo City are closely related to the construction work contract agreement whose object is dormitories as one of the programs of the Ministry of Religion of the Republic of Indonesia which is intended for every school with madrasa status throughout Indonesia. Based on the data, it turns out that work that is already 30% in progress can be canceled because unexpected things happen, such as high rainfall in Gorontalo in September 2021 which resulted in work not being able to continue for some time. Apart from that, it turned out that 80% of the workers used by the contractor were Javanese and because the conditions and atmosphere at that time were still during the pandemic, the workers from Java could not go back to Gorontalo because the island of Java was in lockdown status. This is the reason why the Head of Development of Man 1 Dormitory, Gorontalo City, canceled the work contract because of the contract being castrated, in this case there was a target that was not achieved due to the condition of the workers, weather, and so on.

Construction work is one of the jobs that has various high risks for workers and people who are around it. These risks come from various sources, one of which is noise from various equipment and ongoing activities. One of the jobs that cause high noise in construction work is MEP (Mechanical Electrical Plumbing) work. Based on Permenaker Number 13 Year 2011, the Threshold Value (NAB) for noise that can be accepted by workers is 85 dBA for 8 hours a day. Based on the measurement of the construction of the flats, the MEP work in the form of Beam Separator Elevator Installation, Pipe Fabrication, Electrical Wiring Lighting Installation, as well as Welding and Grinding of Iron Pipe causes noise above the NAB. The highest noise comes from pipe fabrication in the form of iron pipe cutting activities using large grinding tools and bevel machines that produce noise of 107 dBA. From the Daily Noise Dose (DND) calculation, the noise generated from MEP work has a dangerous risk level for workers' hearing. Risk control efforts that can be done are preventive actions based on the K3 hierarchy in the form of administrative controls such as changing working hours or shifts and conducting safety talks before work is carried out. In addition, another preventive measure is the use of PPE such as ear plugs. Based on the calculation of the noise reduction level, the use of ear plugs has not reduced the noise level to reach the NAB, so it is recommended that workers in pipe fabrication work use ear muffs to reduce noise exposure.

. The construction sector is a high-activity sector, making it prone to accident hazards. Therefore, safety analysis is useful for identifying and mitigating risk factors and potential causes of disruptions. Personal Protective Equipment (PPE) is one of the efforts to protect workers from the hazards of workplace accidents. The purpose of this occupational safety and health (OSH) study is to analyze the causes of workplace accidents and the impact of using Personal Protective Equipment (PPE) at PT. Bagas Patih Pratama to enhance employee safety and reduce accident risks in the workplace. The data collection technique in this study involves questionnaires or interviews with workers to gather the necessary information. This study evaluates workers' attitudes towards health and safety conditions, knowledge of safety protocols, and the challenges faced during work. The survey results show that the majority of workers have a high level of awareness and understanding of workplace safety and the importance of using Personal Protective Equipment (PPE). However, only a few workers consistently comply with established safety protocols. The study also highlights the importance of using Personal Protective Equipment (PPE) to reduce hazards when working. It is recommended that the company enhance safety training programs and closely monitor the use of PPE to minimize workplace accident risks in the future.

The aim of limestone mining activities is to obtain the main raw material, namely limestone, which can then be used as a construction raw material such as cement. This data collection method is to collect primary data obtained from identifying activity locations and secondary data obtained from Journal Reviews and other scientific articles and then compiling them into a narrative. From the results of this analysis, it can be seen that there is a positive impact, namely the recruitment of workers from the local area and a negative impact, namely a decrease in ambient air quality, a decrease in water quality, soil erosion, disruption of flora and fauna and plant vegetation.

Construction projects are related to infrastructure development in Indonesia, which is an important foundation for economic growth by supporting mobility, trade, and connectivity between regions. Infrastructure development also supports the utilization of labor resources in Indonesia. This research aims to analyze the availability of labor in a construction project. The Resource Leveling method is used to level the labor needs in the project. The results showed that there was an allocation of labor that exceeded the maximum daily availability before equalization. The initial allocation based on qualifications showed that the maximum number of workers consisted of 2 foremen, 1 head carpenter, 1 head ironworker, 1 head mason, 5 carpenters, 5 ironworkers, 1 mason, and 13 workers. After equalizing the workforce, the maximum number of workers required is 1 foreman, 1 head carpenter, 1 head ironworker, 1 head mason, 4 carpenters, 4 ironworkers, 1 mason, and 13 workers. This research emphasizes the importance of workforce equalization to avoid over-allocation and ensure efficiency in construction projects.

The condition of work accident risk is a critical factor that needs to be taken seriously. Related to the construction of the Ciputra Hospital Project located on Jl. Made Selatan - Citraland Surabaya, the Ciputra Hospital project is planned to be built on nine floors with a building area of 23,000 m2, which will allow for various occupational accident risks. So, a risk analysis is needed to identify hazards that can occur. In this study, data collection was carried out through interviews and also distribution questionnaires. Questionnaires are used to find probability and severity scales, and questionnaires are distributed to project expert staff. After obtaining the results from the questionnaire, a risk assessment is carried out by finding the probability index and severity index and then determining the category with the risk matrix. After determining the category, the analysis was carried out using the bowtie method. The result of this study is to determine the most dominant risks, namely workers being punctured by sharp equipment when installing formwork, workers falling from a height when installing formwork, and workers being hit by a bar bender machine when forming. After analyzing using the bowtie method, it was found that the causes of the risk of accidents that occurred included workers in a tired condition, lack of concentration, and carelessness, incomplete use of PPE, undisciplined workers at work, no safety at the job site, bad weather, inexperienced workers, poor machine conditions.

Construction workers are often exposed to high risks of injury and illness due to potentially dangerous work environments. Therefore, the use of Personal Protective Equipment (PPE) is very important to protect them from various threats on construction sites. Literature research conducted in recent years has provided consistent evidence regarding the benefits and importance of using PPE in the construction industry. Various types of PPE, such as safety helmets, safety shoes, protective eyewear, respirators, and gloves, have been shown to be effective in reducing the risk of physical injury and exposure to hazardous materials. Literature studies also show that implementing strict policies related to the use of PPE can reduce the rate of work accidents and work-related illnesses. In addition, proper training and awareness of the importance of occupational safety have been proven to increase worker compliance with the use of PPE. Factors such as adequate availability of PPE, strict standards, a strong safety culture, supervision, and ongoing education are key elements in ensuring effective use of PPE and improving occupational safety in construction workplaces. Therefore, continued emphasis on the correct and consistent use of PPE is a must in efforts to maintain the safety and health of construction workers throughout the world.
