Cost of occupational safety and health using circular number: 11/se/m/2019 on the rehabilitation work of the karajinan irrigation area

To minimize the number of work accidents in construction work, especially in irrigation work. Irrigation construction service providers must provide costs for occupational safety and health purposes taken from the total project costs. This study has the aim of knowing the amount of occupational safety and health costs required according to Circular Number 11/SE/M/2019 (SE19). The research was carried out using the literature study method where the stages of data analysis were compiling a list of risks that occurred, assessing risk, mitigating risk, calculating occupational safety and health costs with the price survey results and calculating the percentage of occupational safety and health costs to the contract. The results showed that 27 occupational accidents and safety risks were identified with 18 low risk categories and 9 moderate risks. The required occupational safety and health cost based on the contract is Rp. 11,961,000.00 while the cost based on the SE19 regulations is Rp. 18,350,000.00. questionnaire The showed that the risk this around IDR 956.4 the cost of work opportunity cost


Introduction
The mandate of circular letter Minister of Public Works No. 11/SE/M/2019 which regulates technical instructions for the cost of implementing a construction safety management system. In every construction project implementation, of course all parties involved in it hope that there will be no work accidents so that project success can be achieved. One of the efforts made by construction service companies to minimize the number of accidents is to implement a construction occupational safety and health management system (SMK3). Construction service providers must provide costs for occupational safety and health purposes which are taken from the total project costs even though these costs are included in the general and non-specific cost categories listed in the contract.
Research related to OHS financing in the construction sector has been carried out and resulted in an analysis related to the different OHS costs of each project that became the research review. This is because there are no identical projects and only similar projects.
To analyze the work accident cost on occupational safety and health risk handling at the construction project of Hasanuddin University Faculty of Engineering. Methods: An explorative study with a retrospective approach, analyzed the occupational accident records and Microsoft Excel for the safety cost data. The case samples were: 80 workers at ADHI Company Hasanuddin University Engineering Faculty Construction Project who experience occupational health during the project. The instrument used in this study was a questionnaire and interviews. Results: The results showed that the cost of OSH risk handling in this project is around IDR 956.4 million, the cost of work accidents handling is around IDR 64,534 million, the opportunity cost is around IDR 3475 million, cost of OSH risk controlling program is around IDR 724,275 million. Conclusions: The value of the benefit-cost ratio is 1.2 or ≥1, which means the OSH program cost investment by ADHI Company is categorized as beneficial for the company. The safety cost data presented in this paper may be useful for practitioners to direct resource investment. [23] Economic Evaluation of Occupational Safety and Health Interventions from the Employer Perspective: A Systematic Review ,The aim of this systematic review was to evaluate the costeffectiveness of occupational safety and health interventions from the employer perspective.A comprehensive literature search (2005 to 2016) in five electronic databases was conducted. Pre-2005 studies were identified from the reference lists of previous studies and systematic reviews, which have similar objective to those of this search.A total of 19 randomized controlled trials and quasiexperimental studies were included, targeting diverse health problems in a number of settings. Few studies included organizational-level interventions. When viewed in relation to the methodological quality and the sufficiency of economic evidence, five of 11 cost-effective occupational safety and health (OSH) interventions appear to be promising.present systematic review highlights the need for highquality economic evidence to evaluate the cost-effectiveness of OSH interventions, especially at organizational-level, in all areas of worker health. [24] The research problem on this take a look at is the Cost Budget Data Plan for numerous projects, specifically constructing, road, bridge and drainage initiatives. Details of the implementation of occupational safety and fitness (OSH) in the field of construction initiatives, namely occupational protection and health (OSH) guidance , socialization and promoting of occupational protection and health (OSH), work defensive device, non-public shielding equipment, coverage and licensing, safety personnel and occupational health (OSH), health facilities, occupational protection and health (OSH). Fulfillment of occupational safety and fitness (OSH) for creation projects covering roads, bridges, homes and drainage varies from at the least 0.8% to 0.7% of mission value. The smallest occupational safety and health (OSH) fees for street creation projects are zero.Eight% for bridge production tasks zero.Nine% for drainage production tasks 1.2% and the largest for constructing creation tasks is 1.7% of project expenses. With wonderful fee from diverse initiatives. [25] As well as projects for the development and management of primary and secondary irrigation systems in irrigation areas with an area of less than 100ha.Rehabilitation project for Karajinan Irrigation Area, Girijaya Village, Nagrak District. Limited time and wide scope of work will lead to accidents that result in the need for Personal Protective Equipment (PPE) and cost requirements for project occupational safety and health.

Occupational Health and Safety Management System (SMK3)
Minister of Manpower Regulation No. 5 of 1996, the occupational safety and health management system (SMK3) is the whole part of the management system which includes organizational structure, planning, responsibilities, implementation, procedures, processes and resources needed for development, implementation, achievement, review and maintenance of occupational safety and health policies to control risks related to work activities so as to create a safe, efficient and productive work environment.

Hazard and risk identification
Jawat and Suwitanuwijaya explained that danger is all conditions and actions that have the possibility of causing accidents, damage or injury to humans. Hazard identification is carried out to find out, recognize and estimate risks that may occur in operating systems, equipment, procedures and work units. The risks that have been identified are then analyzed for their severity values for later control of the identified hazards[5]

Risk Assessment
According to Suharto, project risk is characterized by the following factors: a. Risk events (shows the negative impact that can occur on the project). b. The probability of the event occurring (or frequency). c. Depth (severity) of the negative impact / impact / negative consequences of the risks that occur (Indentifikasi Dan Penanganan Risiko K3 Pada Proyek Konstruksi Gedung, Sucita, 2011,87) Risk is formulated as a function of likelihood and negative impact. Risk = Likelihood x Impact, This means that the total amount of risk exposure is the probability of an unfortunate event occurring, multiplied by the potential impact or damage incurred by the event. If you put a dollar value on the impact, then you can value the risk and in a simple way compare one risk factor to another. [5]

Fig. 2. Risk Matrix
To calculate the income is the multiplication of the probability score and the impact score obtained from the respondents. The formula used is Risk = probability x impact/severity.

Occupational Health and Safety (K3) Cost Planning
Based on a literature study that the Bill of Quantity (BOQ) is used as a method for identifying project waste, identifying residual materials, planning, scheduling work, scheduling labor, even as a basis for calculating the budget plan, using either the SNI or BOW methods, and some are using WEB-based estimation. (

Prepare a list of occupational safety and health risks
The preparation of the risk list was carried out by interviewing occupational safety and health workers for the Karajinan Irrigation Area project.

Conduct an occupational safety and health risk assessment
The risk assessment multiplies the value of the level of frequency with the value of the severity level to further determine the risk priority category.

Determine mitigation actions for occupational safety and health risks
Mitigation of occupational safety and health risks is carried out for identified and assessed occupational safety and health risks. Mitigation actions are determined by interviewing the project occupational safety and health personnel and the project site manager.

Perform work safety and health cost calculations
The calculation is done by multiplying the volume of each cost of preparing personal protective equipment (PPE) and occupational safety and health equipment with the price per each item so that the costs of each occupational safety and health implementation activity are obtained.

Calculate the percentage of K3 costs against the contract
The calculation of the occupational safety and health costs that have been carried out is then determined by the percentage with the total contract value of the work.

3.1 Identification of Occupational Safety and Health Risks
Identification of the risk of occupational safety and health incidents during project implementation is carried out through interviews with occupational safety and health personnel. In addition, field observations are carried out to see the risks that may occur due to the implementation of the work. The Karajinan Irrigation Area Rehabilitation Project was carried out within three months using a workforce  Table 1.   Based on data from the Public Works Department, the number of field workers involved in the implementation of the di Karajinan project is 20 people. The budget stated in the contract (field costs) does not refer to Circular Letter Number 11/SE/M/2019, only budgets for personal protective equipment and accident insurance. The details are as follows:  The difference in the cost of the comparison of occupational safety and health using Circular No. 11/SE/M/2019 is not too significant to the contract value, meaning that the preparation of occupational safety and health costs for the rehabilitation of the Karajinan Irrigation Area can use the Circular Letter approach, the cost reference is based on Circular Letter No. 11/SE/M/2019. 11/SE/M/2019 can provide a guarantee that the budgeted costs have included a risk assessment on the Karajinan Irrigation Area Rehabilitation work, so that project service providers can guarantee their activities safely.

Conclusion
The results showed 27 occupational accidents and safety risks with 18 risk categories and 9 moderate categories in Karajin Irrigation work. Based on this assessment, to ensure occupational safety and health in these activities, the budget is based on Circular No. 11/SE/M/2019. The K3 budget based on the SE19 regulations is Rp. 18,350,000.00. For the rehabilitation work of the Karajinan irrigation area as stated in the contract, Rp. 1,354,727,000.00, the cost of occupational safety and health stated in the contract is Rp. 11,961,000.00. Comparison of the cost of occupational safety and health between the field and the price in the regulation is where this is due to the SMK3 item listed in SE No. 11/SE/M/2019 in accordance with the rules such as preparing an Occupational Safety and Health Plan, Socialization, Signs while in the field it is only on providing PPE, handling Covid and licensing.
