Abstract

Gardu Induk (GI) adalah suatu instalasi yang terdiri dari peralatan listrik yang berfungsi untuk mengubah tenaga listrik tegangan tinggi ke tegangan tinggi lainnya atau tegangan mengengah. Salah satu pekerjaan yang dilakukan oleh operator gardu induk adalah memonitoring atau memantau besaran listrik tiap bay yang ada pada gardu induk salah satu contoh seperti bay trafo dan bay penghantar lalu dicatat di setiap perkiraan beban puncak. Besaran listrik yang dicatat dan dilaporkan adalah arus, tegangan, daya aktif, dan daya reaktif. Kondisi ini kurang ideal mengingat operator tidak setiap waktu dapat memantau di ruang kontrol. Operator gardu induk memiliki peranan sebagai pengamat untuk tiap kondisi peralatan yang ada pada gardu induk. Internet of Things adalah sebuah konsep dimana suatu objek atau benda disematkan dengan teknologi seperti sensor dan perangkat lunak untuk berkomunikasi, mengontrol, menghubungkan dan bertukar informasi dengan perangkat lain selama masih terhubung ke Internet.Yang lebih efektif dan efisien adalah pemantauan arus dan tegangan jaringan listrik berbasis Internet of Things, yaitu sistem yang merekam data arus dan tegangan selama pemantauan dan memungkinkan hasil pemantauan dilihat dari jarak jauh melalui Internet. Data yang dikirim ke operator adalah data pengontolan arus dan tegangan pada gardu induk berbasis IoT melalui aplikasi Blynk.   Kata kunci: Operator, Gardu Induk, Monitoring, Blynk

Abstract

Abundant cobalt reserves, especially those associated with nickel laterite, have significant potential in the cobalt industry. The demand for cobalt is expected to increase in the world market along with the increasing use of electric cars. This research was conducted using primary data collection methods in the field as well as descriptive quantitative methods with a literature study approach and are descriptive in nature by conducting in-depth studies and studies of the potential for cobalt on Gag Island. Laterite deposits contain garnierite minerals which are rich in nickel such as on Gag Island where the concentration of cobalt is relatively high. Cobalt is anticipated to dissolve and migrate more significantly in hot and humid environments which could lead to increased concentrations of cobalt in laterite deposits such as those in the Gag Islands. For example, the solubility and precipitation of cobalt can be affected by the pH (acidity) of the solution and the amount of oxygen present in the environment. Geochemical analysis of laterite nickel drill with cobalt (Co) elements in the study area. Nickel-containing rocks weathered in hot and humid environments, a layered structure known as a nickel laterite profile is created from top to bottom. Solutions containing cobalt can pass through laterite layers, especially through pores and cracks in the rock.

Abstract

PT Chia Jiann Indonesia Furniture is one of the manufacturing companies in Jepara. The main raw material used for production is mahogany wood, but the inventory of raw materials at PT Chia Jiann Indonesia Furniture has not been well planned which results in mahogany wood inventory in the company is not optimal.  Based on these problems, this research will use the EOQ (Economic Order Quantity) method and the POQ (Period Order Quantity) method. This method can calculate the inventory of mahogany raw materials in the company to be minimum and more efficient so that the company can get maximum profit. The results of this study show that the calculation  of Total Inventory Cost (TIC) using the EOQ method is Rp.  134,405,772 and Total Inventory  Cost (TIC) using the POQ method is Rp.  118,500,000. The use of the POQ method has a smaller Total Inventory Cost (TIC) when compared to using the EOQ method and company policies for mahogany raw materials, so that if you use the POQ method the company will save Rp. 9,750,000. So, the inventory control method at PT Chia Jiann Indonesia Furniture should be done with the POQ method.

Abstract

In the production process of making plastic sacks there are several processes, one of which is Cutting Sewing. Where Cutting Sewing is an automatic cutting and sewing process on plastic sacks. In this process, quality checks are carried out before packing, because if there is a defect in the sack it will affect the quality of the product produced. During the Cutting Sewing process, there are several criteria for defects, namely stringy/stretchy sacks, slanted cuts, and cropped images that exceed the target for defects. So that quality control can be carried out to find out how defective the process is. This study aims to determine the level of defects and causes of product defects produced. Using the Nine Tools Method, it will be known how many levels of defects and influences or problems that occur in the Cutting Sewing process. Nine tools are 9 quality tools that are used to determine the level of defects and problems as well as improvements regarding product defects with the aim that defects can be controlled. By using Control Chart P, Pareto Diagrams, Histograms, Scatter Diagrams, Fishbone, Stratification, Affinity Diagrams, Interrelationship Diagrams, and Tree Diagrams. The total production results are 312,318 pieces of plastic sacks with a total number of defects of 28,154 sheets. The results of the analysis showed that the highest defect rate occurred in the fibrous/drain sack with a total of 27709 defects or a 98.4% disability rate. There are several production defects that are not controlled and the distribution of the number of defects is not evenly distributed. The most common cause of defects is humans who are not careful because many requests are made and because the machines used are in poor performance.
