Abstract

Pada masa globalisasi seperti saat ini, industri berlomba-lomba untuk dapat menjalankan produksinya dengan efisien. Semakin efisien suatu proses yang dijalankan maka semakin rendah pula cost yang akan dikeluarkan. Demikian pula yang terjadi pada Line Rear Axle Assy, dengan mempunyai efisiensi lintasan sebesar 88,28%, lini produksi ini mempunyai waktu menganggur, sehingga kapasitas produksi menjadi rendah dan mengakibatkan Loading vs Capacity (LVC) lini tersebut tinggi, yaitu menyentuh angka 126%. Dengan metode penyeimbangan lintasan (line balancing), kita coba untuk meningkatkan efisiensi lintasan yang nantinya berdampak pada peningkatan kapasitas produksi dan juga akan menurunkan LVC. Setelah dilakukan perbaikan, dengan kondisi lintasan yang semakin seimbang, efisiensi lintasan pun meningkat dari 88,41% menjadi 97,96%. Perubahan efisiensi ini, berimbas pada kapasitas produksi yang juga ikut bertambah sebesar 9,23%. Dengan naiknya kapasitas produksi sebesar 9,23%, berdampak pula pada penurunan LVC dari 126% (waktu kerja 3 shift + 4 Sabtu + 4Minggu), menjadi 119% (waktu kerja 3 shift + 4 Sabtu), kapasitas produksi meningkat 6 unit/jam, total keuntungan perusahaan bertambah sebesar Rp.9.179.160.000.-

Abstract

A beautiful green environment certainly makes the home environment beautiful. But lush trees and greenery also pose a problem if the litter is left scattered. Banana stem waste also adds to the waste in the environment. In addition to looking dirty, it can also invite the presence of insects, other animals that can be dangerous such as snakes. Residents can use dry leaf waste and banana stem waste into a valuable product. Dried foliage can be turned into compost, while banana stem waste can be processed into delicious chips. So the solution taken is to provide training on how to process environmental waste such as dry leaves, twigs and others into compost. The next training is to make chips from banana stalks. Then provide training on how to choose packaging and create attractive labels. Finally, the training determines the selling price of the product produced. The results of the training are compost products and chips as well as packaging for compost and chips that can be used by themselves or to start entrepreneurship to increase family income. In addition to products, residents' knowledge is increasing about choosing good packaging and how to determine the selling price of products.

Abstract

ABSTRACTThis study aims to determine the engine performance (torque, power, and air fuel ratio / AFR) with a variation of the Standard and aftermarket Ignition Coil on the Honda Astrea Legenda 100cc motorbike. The research method used is the experimental method and carried out at the rotating speed (rpm) change, namely by turning on the engine and opening the gas 3000 rpm to full throttle. From testing the engine performance, it can be concluded that the greatest power is obtained by using the Aftermarket SGP RM 80 Ignition Coil with a power of a maximum of 6.83 hp at 6100 rpm engine speed. The biggest torque was also obtained by the Aftermarket SGP Ignition Coil RM 80 of 5.89 ft-lbs at 6100 rpm engine speed. From AFR testing, it can be concluded that the level of air and fuel ratio (AFR) produced by the aftermarket ignition coil is more fuel efficient based on the Stoichiometric graph. Using this aftermarket ignition coil starts from the AFR 17.66: 1 to 14.50: 1. Keywords: Motorcycle, ignition coil, Power, Torque, AFR

Abstract

Using various new materials in current technological developments, besides providing opportunities for better product development, can also open research opportunities in the world of materials. In the last decade, magneto-dielectric materials have been extensively researched for use in various applications in the high-frequency spectrum. Before it can be implemented as a material that can be used widely, its characteristics must be identified first. This paper proposes the process of characterizing the electrical and magnetic properties of the high-frequency spectrum. Mathematical analysis carried out through simulations has identified the electrical and magnetic properties of the magneto-dielectric material so that the permittivity, permeability, and losses of both dielectric and magnetic can be determined. Based on the analysis results of several magneto-dielectric samples, the permittivity, permeability, and losses are directly proportional to the composition of magnetite (Fe3O4) in the magneto-dielectric material. With these results, the use of magneto-dielectric materials can be increasingly adapted to the electromagnetic properties they have.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kenaikan temperatur terhadap tingkat kegagalan produk pada mesin filling kemasan sachet bubuk, dengan fokus khusus pada kerusakan sealing seperti seal break dan seal crack. Mesin filling memiliki peran penting dalam proses produksi, terutama pada tahap sealing yang sangat sensitif terhadap fluktuasi suhu. Ketidakkonsistenan suhu pada sealing jaws menyebabkan penyegelan yang tidak sempurna, yang berdampak langsung pada mutu produk dan efisiensi produksi. Metode penelitian dilakukan secara eksperimental melalui dua tahapan: sebelum dan sesudah perbaikan sistem termal, yakni dengan pemasangan kain teflon tahan panas pada sealing jaws. Data dikumpulkan melalui pengukuran suhu kerja sealing jaws, jumlah produk gagal, dan efisiensi waktu produksi. Hasil pengujian menunjukkan bahwa sebelum perbaikan, laju perpindahan panas mencapai 323,4 Watt dengan jumlah produk gagal yang tinggi. Setelah pelapisan teflon, energi panas turun menjadi 270 Watt karena adanya tambahan isolasi, yang menghasilkan distribusi suhu lebih stabil dan penurunan signifikan pada kegagalan produk. Selain itu, waktu pemanasan mesin meningkat efisien dari 10 menit menjadi 9,5 menit. Hasil analisis menunjukkan bahwa pengendalian suhu pada mesin filling sangat penting untuk menurunkan kerusakan kemasan. Pemasangan kain teflon terbukti efektif dalam menstabilkan distribusi panas, meningkatkan kekuatan sealing, dan menekan tingkat kegagalan produk hingga di bawah batas ambang industri (<5%). Penelitian ini mendukung penerapan prinsip perpindahan panas konduksi dan teori material termal sebagai pendekatan sistematis dalam peningkatan kinerja sistem mekanik mesin filling.
