Abstract

Pipa merupakan salah satu equipment terpenting didalam boiler. Memperbaiki kebocoran pada pipa boiler membutuhkan banyak waktu dan biaya perawatan yang tinggi. karena itu kerusakan pipa pada boiler harus segera diperbaiki dan dicegah, agar tidak terjadi. Kebocoran pada pipa dikarenakan kurangnya ketahanan suatu material dalam menahan pressure fluida dan penipisan ketebalan, maka pada penelitian ini menggunakaan pengujian struktur mikro untuk mengetahui kandungan suatu material. Dari hasil pengujian yang didapat perlit pipa yang bocor 48% dan pipa yang tidak bocor 31,5%, sedangkan hasil dari ferrite pipa yang bocor 43,5% dan pipa yang tidak bocor 35%.maka pipa yang bocor tingkat Pada struktur mikro sampel pipa embedded yang tidak bocor didapatkan hasil kandungan perlit sebesar 31,5% sedangkan kandungan ferrit didapatkan sebesar 35%, maka dapat disimpulkan kandungan baja tersebut bersifat lunak dan didapatkan nilai gran size atau butiran fasa struktur mikro sebesar 7,24071. Pada struktur mikro sampel pipa embedded yang bocor mempunyai kandungan perlit sebesar 48% lebih tinggi kandungan perlit, dibandingkan kandungan ferrit lebih rendah dari perlit dengan nilai 43,5% sehingga baja tersebut mempunyai tingkat kekerasan yang cukup tinggi, yang disebabkan oleh perlit, dan didapatkan nilai gran size atau butiran fasa struktur mikro sebesar 5,9039.

Abstract

Penggunaan tali tambang pada capstan telah digantikan dengan round link chain pada undertow system di PT. Hindoli MSL dengan kepentingan safety. Namun dalam operasionalnya seringkali terjadi kegagalan berupa putusnya chain dengan frekuensi tinggi. Dalam investigasi yang dilakukan, pola patahan chain menunjukkan patah akibat beban fatik. Penggunaan operasional secara SOP tidak mengindikasikan terjadi overload dimana beban tersebut memiliki asumsi life time 7,1 tahun. Namun pada praktiknya, kegagalan telah terjadi sebelum life time berakhir. Hasil peninjauan lapangan, terdapat faktor eksternal yang mempengaruhi kegagalan yaitu roda lori yang abnormal. Roda lori tidak berputar pada rel melainkan hanya menggesek pada rel yang berakibat nilai koefisien gesek gelinding 0,001-0,002 menjadi 0,74 yang berimbas pada meningkatnya tegangan hingga overload. Selain itu terdapat pembebanan melebihi SOP di bawah tegangan overload yang berdampak pada life time yang lebih singkat. Pada faktor internal, terdapat komposisi kimia dengan jumlah persentase lebih rendah dibanding persentase standar.

Abstract

This study investigated the effect of varying heat treatment on the hardness of expeller arm digesters. Wear is a surface failure that can alter the surface profile and affect the performance of components. This is due to the release of particles from the surface of the material and the low hardness of the Expeller Arm Digester which is made from low carbon steel with a carbon content of 0.189%. One method of increasing its hardness is through heat treatment in the form of a hardening process. The study investigated hardening using different holding times (25, 30 and 35 minutes) and cooling media (water, brine and oil). Vickers hardness tests were then carried out on both the original expeller arm digester samples and the treated samples.  The best results were obtained with a 35 minute holding time and water cooling, giving a hardness of 548.12 VHN and an influence percentage of 99.45%. The lowest hardness of 276.76 VHN and 0.7% influence percentage was observed with a holding time of 35 minutes and oil cooling. The microstructure affects the hardness of the steel, the steel with a higher martensite content will cause an increase in the hardness of the steel.

Abstract

Pelaksanaan Tridharma Perguruan Tinggi menuntut dosen untuk berperan aktif dalam kegiatanpengabdian kepada masyarakat (PKM) melalui kolaborasi dengan mahasiswa dan masyarakat.Kegiatan ini bertujuan untuk menjawab berbagai permasalahan yang dihadapi masyarakat,khususnya terkait peningkatan keterampilan dan perekonomian. Di Kota Palembang, jumlahpelaku UMKM pengrajin sepatu kulit sangat terbatas, tercatat hanya lima pengrajin yang masihaktif. Kondisi tersebut dipengaruhi oleh keterbatasan peralatan serta dukungan dalam aspekpemasaran. Dari sisi teknologi, pengrajin mengalami kesulitan dalam memperoleh akses terhadapperalatan modern karena kendala biaya, sehingga kapasitas produksi sangat rendah, yakni hanyasekitar dua pasang sepatu per hari. Jumlah ini jauh di bawah kebutuhan ketika ada undangan untukmengikuti pameran, yang biasanya membutuhkan 20–30 pasang produk. Melalui kegiatan PKMini, tim memberikan bantuan peralatan berupa mesin seset kulit, mesin post bed, shoe last berbagaiukuran, serta mesin press sepatu dengan harapan dapat meningkatkan kuantitas dan kualitasproduk yang dihasilkan. Selain itu, tim juga memberikan pelatihan teknik pemasaran berbasismedia sosial guna mendukung keberlanjutan usaha, sehingga peningkatan kapasitas produksidapat diimbangi dengan meningkatnya permintaan pasar.Kata kunci : Pengrajin Sepatu, Mesin Post bed , Mesin Seset kulit, Mesin pressSepatu, Pemasaran Digital

Abstract

The need for electrical energy is increasing with economic growth. One of the government's efforts to increase electricity production is with the existence of Steam Power Plants. Boiler or steam generator a tool utilized to generate steam which consists of two important components, namely a heating system to generate heat from burning fuel and a system that converts water into steam. The percentage of boiler performance is the percentage of energy absorbed by the steam boiler with fuel input energy. Boiler performance greatly affects the performance of a PLTU where the use of fuel affects the steam produced. This research was carried out using the direct method by taking daily boiler log sheet data for 2 months, namely April and May, using coal calorific values, namely 5615 kcal/kg and 5654 kcal/kg. The results, the highest boiler efficiency was 55.95% with a calorific value of 5654 coal while the lowest boiler efficiency was 36.29% with a calorific value of 5615 kcal/kg. From the results obtained, it can be concluded that the steam flow rate is not constant and the excessive use of fuel causes boiler efficiency to experience conditions that are not optimal. The calorific value of coal is affected by the water content contained in the coal. The higher the water content, the more energy is required for the coal burning process.

Abstract

The rapid advancement of technology has led to the emergence of smart systems that aim to enhance convenience, energy efficiency, and safety. In this study, we present the development of an automatic door and light system utilizing a NodeMCU sensor. The system is designed to automatically control open and close the door, as well as lighting in indoor environments. To implement the system, this experiment utilized the NodeMCU sensors onboard Wi-Fi capabilities, enabling remote control and monitoring via a dedicated mobile application. The application provides users with the ability to customize various system parameters, according to their specific requirements. This development offers a practical and connected solution to automate door and light, increasing safety, comfort and energy efficiency in premise, house or any buildings. It can enable users to control both the door and light remotely, providing convenience and flexibility. This automatic sliding door and light can unlock the system by sending commands through the Blynk application on the user's smartphone, then NodeMCU sensor as a microcontroller will confirm the command and send data to other components to move sliding door and turn on the light, the use of this system is very effective because it makes it easier for users to open and close the door and turn on and turn off the light without extra efforts.
