Abstract

Control Systems have taken essential parts widely from industrial world to military equipment. Control systems in the industrial world determine the quality, speed, cost and efficiency of the manufacturing process known as the Process Control System (PCS). The core of the Control System is conditioning (actuators) and reading conditions (sensors). By synergizing those parts with the coordination of the controller, the process value (PV) can be obtained according to the condition of the set point (SP). To get the proper control characteristics, i.e. the fastest possible response, the lowest possible oscillation and offset (error steady state/ESS), an understanding of the concept of a closed loop control system with a continuous scheme is developed. In this regard, the Automatic Control Laboratory under the Pneumatic and Hydraulic Laboratory at the Department of Mechanical Engineering - POLBAN considered to provide students with an introduction to Automatic Instrumentation and Control. The briefing covered the introduction, mechanism and operation of Automatic Instrumentation and Control systems. Therefore, tools were required as a medium for achieving the above competencies, one of which was the modernization of pressure regulators in order to strengthen the Laboratory. Through this research, a rejuvenation and modernization of the control system were carried out by applying a proportional, integral and differential (PID) control system. It was based on a programmable logic controller (PLC) equipped with a human machine interface (HMI) to make it easier to enter set points and PID parameters, to be practical in operation and effective in monitoring and data acquisition. The result of the pressure regulator modernization had the ability to include servo control process (getting a certain value) and regulatory control process (maintaining a certain value) with a continuous closed loop scheme. The modernized pressure control system could be utilized as a prototype demonstration of the system in an actual environment to study and observe the Proportional, Integral and Differential (PID) control system along with the process of determining the parameters Kp, Ti and Td as Practicum equipment.

Abstract

Mesin Computer Numerical Control (CNC) merupakan peralatan manufaktur yang dikendalikan oleh komputer dengan bahasa numerik. Salah satu jenisnya adalah CNC Milling yang menggunakan sistem hidrolik melalui Hydraulic Power Unit (HPU) untuk proses clamp dan unclamp material kerja. Permasalahan yang ditemukan adalah tekanan hidrolik yang tidak stabil dan suhu HPU yang tinggi akibat beban kerja berlebih (overload), sehingga menyebabkan lemahnya sistem clamping, meningkatnya konsumsi oli hidrolik, serta bertambahnya downtime mesin. Untuk mengatasi hal tersebut, dilakukan modifikasi dan instalasi tambahan pada pompa HPU. Tahapan kegiatan meliputi identifikasi kerusakan, studi literatur, perancangan modifikasi, pengadaan komponen, instalasi, pengujian, dan evaluasi hasil. Hasil modifikasi menunjukkan bahwa penambahan satu unit pompa HPU beserta instalasi pendukung mampu meningkatkan tekanan hingga 80 bar dan menurunkan temperatur HPU sebesar 28,2°C. Selain itu, konsumsi oli hidrolik turun menjadi 14 liter per bulan, dan nilai Downtime to Equipment (DTE) hidrolik berkurang hingga 0,07%. Berdasarkan hasil tersebut, modifikasi sistem HPU terbukti efektif dalam meningkatkan stabilitas tekanan, menurunkan temperatur operasi, serta mendukung peningkatan produktivitas mesin CNC Milling yang telah dimodifikasi.

Abstract

Electrical energy is one of the essential needs for garment entrepreneurs in Cileungsi, Bogor Regency, West Java, to support their production activities. However, frequent power outages in the region often disrupt the production process. The Firman FPG1510 RV1-C generator set (genset) can serve as a solution to overcome these outages, but the unit was found to be inoperable after initial evaluation. An overhaul maintenance was performed after component-level servicing failed to restore stable operation. The results of the overhaul process were evaluated through performance testing, which included fuel consumption testing under a 570Watt electrical load and exhaust emission measurements. The performance test results show that the highest fuel consumption rate (ṁbb) was 0.000089 kg/s at 3177 RPM. At the same speed, the highest brake specific fuel consumption (BSFC) was recorded at 0.21456 kg/kWh. The maximum electrical efficiency (ηt) was achieved at 3006 RPM with a value of 17.35%, while the highest brake thermal efficiency (BTE) was 43.45% at 2973 RPM. The emission test after overhaul produced CO levels of 0.92–2.72% and HC levels of 80–153 ppm, both of which comply with the Bandung City emission standards for gasoline engines (CO 4.5% and HC 1200 ppm). A comparison between the post-overhaul performance and the manufacturer’s specifications shows that the indicator shaft power after overhaul reached 1.42 kW at 3006 RPM, compared to 1.17 kW at 3000 RPM in the standard specification. This indicates a 21% increase in shaft power as a result of the overhaul maintenance.

Abstract

Integritas struktur baja di lingkungan pertambangan tropis mempengaruhi kualitas sistem pelapisan pelindung proses konstruksi membuat  sangat rentan terhadap korosi. Pelapisan permukaan baja merupakan metode mitigasi yang  efektif digunakan. Penelitian ini bertujuan untuk mengevaluasi ketebalan dan kualitas pelapisan struktur baja piperack 3115 di area tambang terbuka, melalui pendekatan studi kasus lapangan. Proses pelapisan dilakukan secara manual menggunakan kuas dan roller, dengan metode persiapan permukaan berdasarkan standar SSPC-SP2 dan SSPC-SP3. Masalah yang diangkat dalam studi ini adalah adanya deviasi ketebalan pelapisan yang signifikan dari spesifikasi teknis, yang berpotensi mempengaruhi performa dan daya tahan sistem pelindung. Hasil pengukuran ketebalan lapisan kering (DFT) menunjukkan nilai existing coat sebesar 674 µm, lapisan primer 926 µm (spesifikasi 150 µm), dan top coat 1038 µm (spesifikasi 75 µm). Meskipun pelapisan dilakukan dalam kondisi lingkungan yang relatif stabil dan sesuai standar (suhu 29–33 °C, kelembaban 70–85%), kelebihan ketebalan berisiko menimbulkan retak atau delaminasi akibat tegangan internal. Penelitian ini menunjukkan perlunya peningkatan pengawasan mutu dan pelatihan aplikator di lapangan agar hasil pelapisan lebih seragam, aman, dan sesuai spesifikasi kondisi ekstrem di lingkungan pertambangan. Rekomendasi diberikan untuk peningkatan pemantauan proses dan pelatihan tenaga kerja untuk meminimalkan deviasi selama aplikasi pelapisan secara manual di proyek-proyek industri serupa.

Abstract

The Pre-Delivery Installation (PDI) Department of PT. XYZ is tasked with carrying out the installation process of imported heavy equipment attachment units, including one of the leading excavator units. Obstacles that arise can affect installation productivity. The gap between the actual installation results of 78 units and the company's target of 156 units requires a solution or resolution to improve the process that can be implemented. Therefore, it is necessary to investigate the wait time associated with decreased productivity, which is the longest component of the installation process. This work has a purpose to analyze lead time of the excavator attachment unit installation process. The method is applied with a time study approach referring to data sheets and observations, then processing lead time data using pie charts, Pareto diagrams, and fishbone diagrams. Furthermore, we review the planning calendar, realization, and improvement engineering. Reduction is carried out by providing additional work personnel and procuring sanding machine tools to reduce the installation and critical time of the planning calendar. The realization condition for 562 minutes with the implementation of improvement engineering is reduced to 318 minutes. Thus, it can speed up implementation time of the excavator attachment in unit installation process to 224 minutes or 44%.
