Abstract

This research investigates problems in projects that have been carried out by CV. MKE, such as late work occurring in the eighth week of progress. Where in the eighth week there was a deviation of -2.618%. So an analysis of the acceleration of work is needed. In this research, the analysis was carried out using the Crashing method by adding working hours (overtime) with the help of Microsoft Project 2016 software to find the critical path. After getting the critical path results, an analysis of time and costs will then be carried out. Based on the results of the analysis of time and cost calculations using the Crashing method, it shows that with the additional working hours, the project duration can be reduced by 11 days from the normal duration of 140 days, so that the total work duration becomes 129 days and achieves an efficiency of 7.857%. Then there was a change in the total project cost of Rp. 11,547,870,543.73 from the normal fee of Rp. 11,575,779,000.00 with a cost difference of Rp. 27,908,456.27 and get an efficiency of 0.241%.

Abstract

Penelitian ini mengevaluasi kapasitas produksi PT. XYZ dalam memenuhi permintaan produk Under Bracket 59 yang tinggi menggunakan metode Rough Cut Capacity Planning (RCCP). Berdasarkan analisis data permintaan dan waktu proses produksi di berbagai stasiun kerja, ditemukan bahwa stasiun Heating mengalami kekurangan kapasitas pada bulan April (-9%) dan Agustus (-10%). Sementara itu, stasiun Hammer Blocker, Hammer Finisher, Trimming Profile, dan Trimming Hole mengalami kelebihan kapasitas sepanjang tahun, dengan rata-rata kelebihan masing-masing sebesar 47%, 80%, 69%, dan 75%. Untuk mengatasi kekurangan kapasitas, disarankan untuk merevisi Master Production Schedule (MPS) dan menambah jam kerja lembur. Untuk mengatasi kelebihan kapasitas, disarankan untuk menerapkan pendekatan Just In Time (JIT) dan diversifikasi produk. Implementasi strategi ini bertujuan untuk menjaga keseimbangan antara permintaan dan kapasitas produksi, meningkatkan efisiensi operasional, dan kinerja keseluruhan perusahaan.

Abstract

Raw material inventory is a significant aspect in the industry, especially in PT XYZ company where there is a problem of excess inventory, regardless of the number of purchases per order. If the inventory of raw materials is too large, it will increase maintenance costs and storage costs in the warehouse. our abstract must be written in a single paragraph and typed in single space. The EOQ method is used in raw material control to determine the quantity of supply orders to minimize storage costs and supply order costs, minimize out of stock so as to save inventory costs incurred in making cigarette paper to be more efficient, and determine the optimal total inventory cost (TIC) in the company. The results of the proposal obtained by calculation using the Economic Order Quantity (EOQ) method are for cigarette paper raw materials in the form of pulp using the EOQ method calculation of 1,054,947.38 kg with a frequency of 3 orders, and Chemical raw materials of 193,939.39 kg with a frequency of 3 orders.

Abstract

Alongside the increasing potential of the agriculture and plantation sectors in Minggirsari Village, Blitar Regency, there have been concerns among farmers regarding the decreasing supply of both subsidized and non-subsidized chemical fertilizers. However, these concerns were validated with the invention of an automatic anaerobic bioreactor by Nawang Sonia in 2023. The device is capable of reducing the fermentation process time from the initial 14-21 days to just 3-5 days. Although the designed device still had some functional limitations hindering its performance, a redesign was deemed necessary. The redesign was conducted using the Quality Function Deployment method through the distribution of questionnaires or Voice of Customer. Subsequently, a House of Quality was obtained, which served as the basic concept for the device's redesign. From this research, eight features were added to the device. The results showed that the device was more optimal, flexible, and effective than the previous anaerobic bioreactor design.

Abstract

PT. SJA is a food distributor company located at Jalan Kalianget No.50-52 Surabaya. The main distribution product is UBM biscuits located at Waru, Sidoarjo. The operational costs used in carrying out distribution using the initial route are IDR 25,008,650 for delivery every day. Based on the large costs, a complicated route plan will occur in order to find the minimum costs possible. In optimizing the distribution routes above in order to minimize shipping costs to PT. SJA, a saving matrix method is used. This method can determine product distribution routes to all product marketing areas by determining the route chosen and the capacity of the vehicle used so that the closest route and lowest transportation costs are obtained. Based on the results of the analysis of the research objectives carried out, it can be concluded that the proposed route obtained from processing using the saving matrix method produces differences in terms of costs and transport capacity in March 2024, the company before using this method required shipping costs of IDR 25,008,650 and after using the saving matrix method the company can save costs by 22.34%, namely Rp. 19,421,100

Abstract

A project is a temporary activity that has a beginning and end specified in time and scope. To support the success of a project, project management needs to be carried out. In general, a project is held by a contractor. contractors who have the obligation to carry out work according to the plan, schedule the activities to be carried out, provide supporting tools for project implementation. One company operating in this field is CV. Andhika Kencana. Now CV. Andhika Kencana is carrying out work on several projects, one of which is the water pipe installation project at PT. X. This research aims to guarantee the water pipe installation project at PT. X is right in terms of cost, quality and time. This research uses 2 methods to analyze project work schedules, namely the Critical Path Method (CPM) and Project Evaluation And Review Technique (PERT). The results of this research show that the critical path on this project is A-B-C-D-G-H-K-L-M-N-O with different completion times. Using the CPM method, the project can be completed in a total of 65 working days, which is 1.15% faster than the normal time. Meanwhile, using the PERT method, the project can be completed in a total of 66.2 working days with a chance of 70.88%, which is 1.13% faster than the normal time.

Abstract

In the practical and sophisticated world of the manufacturing industry, the best product results are needed. To answer market needs that want products with maximum results and produce them in a short time, the non-conventional Computer Numerical Controlled Lathe (CNC) is available as a machine tool production tool that is controlled using a computer system to cut workpieces which are rotated to determine the roughness value on the workpiece surface. The aim of this research is to obtain the lowest surface roughness results. Using S45C carbon steel material with Sumitomo CNMG 120404-N-Gu-AC8025 brand insert with a Radius of 0.4 mm on the SKT 160A CNC Turning machine. The next process is the process of turning the workpiece with variations in cutting depth of 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm , 0.9mm, 1.0mm, 1.1mm. Using the G96 program code, the feed movement is 0.15 mm/rev with a constant spindle speed of 2700 rpm and using a Stylus as a measure of surface roughness value. By carrying out 1 test on 11 samples, each sample consisting of 3 test points. Based on the results of surface roughness data, the lowest average Ra roughness results for an insert radius of 0.4 mm were 1,115 µm at a cutting depth of 0.6 mm and was included in the roughness tolerance value N6.

Abstract

A contractor is a party hired to complete a job. CV. Andhika Kencana is a contractor who has received wind pipe installation projects ranging from compressor machines to production machines. PT Compressor pipe installation is used to run automotion machines in the production area. Pressurized air is produced from the compressor which will later be connected to pipes until it reaches the automotion machines. The problem here is how to schedule pipe installation so that it is on time and in accordance with the budget that has been determined at the beginning. The methods used in this research are the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT). The results obtained are that the critical path in this project is activities A, B, D, F, H, I, K, M, N, O, and the probability that the wind pipe installation project can be completed in 60 days is 27.09%.
