Every job has the opportunity of the risk because occurrence of work accidents can be caused by various factors. PT. CA is a large distributor of motorcycle spare parts which has activities including receiving goods from fabrication and then storing them in temporary warehouses before being distributed to dealers in various regions. The company's activities have a large potential for accidents due to several operations. To hazard identification, risk assessment, and determining control in any work that occurs or has the potential to occur, it is necessary to analyze using HIRADC. The method used is a descriptive method described in the flow process and then identified possible hazards that occur in each activity step. After the identification process is complete, a risk assessment is carried out to determine the form of control. The object of research is the receiving section of the work area. The results of this study are that the receiving section has 7 existing activities and there are 20 potential hazards that are possible, from these potentials the current control is to maximize APD to minimize danger. The highest level of risk is substantial in the activity of moving cargo to temporary storage or inspection areas with a potential danger of crashing into workers which has an impact on limb injuries, fractures, and even death, so this activity is a concern to avoid work accidents. In addition, it is determined that hazard control is carried out by means of forklift lanes that are not allowed to be passed by workers and control recommendations are in the form of setting SOPs, ensuring that forklifts complete their activities to carry out inspections.

This research was conducted at a company that produces paints such as wall paint, tile paint, floor paint, steel construction paint and many other types of paint. In addition to these types of paint, color and size are additional factors that cause high product variants. Inventory management with ABC analysis is very necessary to control a number of inventories by taking into account the value of the investment. Based on company conditions and literature, the purpose of this study is to be able to classify inventory in the company and be able to determine inventory control based on ABC classification. The research method is divided into four stages, namely data formulation, data collection, data processing, and analysis and conclusions. Data processed is in 2016, available product variants are 941 items with a total product value of Rp 15,477,094,182.00. The results of ABC analysis are 124 product items or 13.18% A class, 211 product items or 22.42% B class, and 606 product items or 64.40% C class of the total number of products available.Key words : Paint, Inventory Control, ABC Classification
Tujuan dari penelitian ini adalah untuk mengetahui dan menganalisa bottleneck yang terjadi saat jam sibuk, agar dapat memberikan masukan atau saran dalam pembagian kedatangan supplier. Tahapan analisa yang dilakukan pertama kali yaitu membuat penjadwalan dalam aktivitas pengamatan, setelah itu melakukan pengamatan terstruktur sesuai dengan jadwal yang sudah dibuat sebelumnya, lalu setiap supplier yang datang akan di record sesuai dengan zona waktu tertentu. Hasil pengamatan penelitian ini diketahui bahwa terjadinya bottleneck terjadi karena jumlah rata-rata kedatangan supplier paling banyak berada di zona waktu 10.00-11.00 yaitu sebanyak 4-5 kali, dan sebanyak 3-4 kali pada zona waktu 14.00-15.00. Jika dibandingkan dengan zona waktu 08.00-09.00 dan 09.00-10.00 maka hasilnya cukup signifikan yaitu hanya 1-2 kali di jam tersebut. Waktu pelayanan yang dibutuhkan setiap kedatangan supplier adalah 20 menit, sehingga pada waktu 10.00-11.00 waktu pelayanan yang terjadi adalah 80 hingga 100 menit, dan pada waktu 14.00-15.00 adalah 60 hingga 80 menit. Kata Kunci : Kedatangan supplier, bottleneck, just in time
The purpose of study is analysis the work posture of the finishing section on the CV. Sarana Teknik, in order to reduce musculoskeletal disorders using the Nordic Body Map, and the Ovako Work Analysis System (OWAS). CV. Sarana Teknik is an industry engaged in processing plastic pellets into various products on demand. These products are medicine caps and toys that are relatively small in size. The study was conducted in the finishing section with 6 operators. Based on the Nordic Body Map questionnaire, 49% of workers or 3 of 6 workers stated that they were somewhat sick to the point where they were examined at 28 points of the body. Then the work attitude analysis that defines the movement of body parts of the back, arms, legs and weight lifted using the Ovako Work Analysis System (OWAS). The results of this study are the body part is very painful, which is dominantly felt by all operators, is back by 100%. The observed work posture is the taking and tidying posture, the result of the analysis is the taking work posture is category 2 which is a dangerous attitude on the musculoskeletal system which results in a significant tension effect so that the posture needs improvement. As for the tidying work posture, category 1 is an attitude that has no problems so this attitude does not need to be improved.
The Covid-19 outbreak that has spread throughout the world has resulted in a significant reduction in the number of users of the aircraft mode of transportation. The decline in the number of passengers was also experienced by PT. Lion Mentari Airlines or often known as Lion Air. This of course will have an impact on decreasing the company's revenue thereby reducing the Company's ability to pay for the rental costs of several of its aircraft. It is necessary to reschedule aircraft flights to increase aircraft optimization so that existing passenger services can be met with a smaller number of aircraft compared to before the Covid-19 pandemic. Flight scheduling at Lion Air is based on market demand, aircraft maintenance programs, aircraft availability per day and airport operating hours. This research will reschedule Lion Air flight paths on Boeing 737-800NG aircraft during the Covid-19 pandemic based on airport waiting time / ground time using the Hungarian method. The waiting time at Soekarno-Hatta airport before optimization was 5,895 minutes and there was a significant decrease in waiting time at Soekarno-Hatta airport after optimization, which was 18.78% or 1,107 minutes to 4,788 minutes, and by using the new schedule, Lion Air, which was originally operating 7 aircraft fleets for these flight routes can be optimized using only 6 aircraft fleets.
