Abstract

Maintaining machine health is crucial for optimizing operational efficiency and minimizing downtime in industrial applications. This paper explores recent advancements in vibration analysis, focusing on developments from the past decade that have transformed the field. Emerging technologies such as machine learning (ML), advanced signal processing, and the Internet of Things (IoT) have reshaped how vibration data is collected, analyzed, and interpreted. These innovations enable real-time data monitoring and more precise fault detection, allowing for early diagnosis and predictive maintenance, which improves machinery reliability and reduces unexpected failures. By incorporating ML and IoT, industries can now implement more advanced predictive maintenance strategies that significantly lower operational costs and enhance machine performance. Furthermore, the use of advanced algorithms allows for more accurate interpretation of complex vibration signals, offering deeper insights into potential machine issues. However, despite these technological strides, there remains a critical need for industry-wide standardization in data analysis methods and reporting practices to ensure consistency and accuracy across applications. This paper provides a comprehensive review of these technological advancements, highlighting both the benefits and challenges they present, and stresses the importance of continued research to fully harness their potential. Ultimately, the findings underscore the transformative impact of these innovations on improving machine reliability and operational efficiency​.

Abstract

Bearing merupakan komponen penting yang memastikan kelancaran operasional mesin pencacah, namun sering mengalami kerusakan akibat keausan, pelumasan yang tidak memadai, dan beban kerja yang berlebihan. Penelitian ini bertujuan untuk menganalisis penyebab kegagalan pada bearing UCFC215 yang digunakan dalam mesin pencacah sampah di Tempat Pengolahan Sampah Akhir (TPSA) Bagendung. Penelitian dilakukan dengan metode studi kasus melalui pengamatan langsung terhadap kondisi bearing yang mengalami kegagalan, diikuti dengan analisis fishbonedan menggunakan teori mekanika. Hasil penelitian menunjukkan bahwa kerusakan bearing disebabkan oleh keausan yang melampaui batas toleransi desain, ketidakseimbangan gaya, dan distribusi tekanan yang tidak merata selama operasi mesin. Gaya aksial yang bekerja secara tidak terduga menyebabkan peningkatan tekanan pada elemen-elemen bearing, mempercepat keausan, dan menurunkan efisiensi operasional. Analisis juga menemukan bahwa pelumas yang tidak sesuai dengan spesifikasi menambah risiko kerusakan komponen. Sebagai solusi, penelitian ini merekomendasikan penerapan perawatan terjadwal, termasuk pelumasan dan pemeriksaan rutin untuk mendeteksi kerusakan lebih awal. Penggunaan bearing dengan kualitas tinggi yang sesuai dengan beban operasional mesin dan pemasangan aksial bearing juga disarankan untuk mengurangi dampak gaya aksial yang bekerja. Langkah-langkah ini diharapkan dapat memperpanjang umur pakai bearing, meningkatkan efisiensi pengolahan sampah, dan mendukung operasional TPSA Bagendung yang lebih berkelanjutan.

Abstract

Penelitian ini mengevaluasi penerapan Analisis Keselamatan Kerja (Job Safety Analysis, JSA) untuk meningkatkan keselamatan kerja dalam proses pengolahan limbah sabut kelapa pada fasilitas pengolahan sampah Bahan Bakar Jumputan Padat (BBJP) di Tempat Pembuangan Sampah Akhir (TPSA) Bagendung, Kota Cilegon. Limbah sabut kelapa yang melimpah memiliki potensi untuk diolah menjadi produk bernilai tambah yakni bahan bakar pendamping batu bara atau co-firing yang dimanfaatkan untuk Pembangkit Listrik Tenaga Uap (PLTU) Suralaya. Dengan pendekatan kualitatif melalui observasi, wawancara dan studi dokumen, penelitian ini menganalisis peran JSA dalam mengidentifikasi bahaya, meningkatkan kesadaran situasional, dan mengoptimalkan efisiensi pengolahan limbah. Hasil yang didapatkan menunjukkan bahwa penerapan JSA efektif dalam memitigasi risiko kerja, meningkatkan partisipasi pekerja, dan meningkatkan kesadaran tentang implementasi keselamatan dan kesehatan kerja (K3). Studi ini merekomendasikan penerapan JSA secara konsisten untuk meningkatkan produktivitas dan meminimalkan risiko kecelakaan kerja dalam pengolahan limbah sabut kelapa di TPSA Bagendung.

Abstract

Dissimilar aluminum alloys welding between AA5xxx and AA6xxx presents significant challenges due toifferences in chemical composition, thermal properties, and electrochemical potential, all of which impact the corrosion resistance of the welded joints. AA5xxx alloys are well-known for their excellent corrosion resistance, particularly in marine environments, while AA6xxx alloys exhibit superior mechanical strength. This study provides a comprehensive investigation into the influence of various welding techniques—such as Gas Metal Arc Welding , Gas Tungsten Arc Welding , Laser Arc Welding, Laser Beam Welding, and Friction Stir Welding on the corrosion behavior of dissimilar joints between AA5xxx and AA6xxx. Each welding process induces distinct microstructural changes within the Fusion Zone and Heat-Affected Zone, which subsequently affect the joint's susceptibility to various corrosion mechanisms, including galvanic corrosion, intergranular corrosion, pitting corrosion, intermetallic corrosion, and stress corrosion cracking (SCC). Additionally, the difference in thermal expansion coefficients between AA5xxx and AA6xxx can generate residual stresses at the joint, exacerbating the risk of corrosion. This paper also explores mitigation strategies, including the optimization of welding parameters, the application of post-weld heat treatment, and the use of anticorrosive films through protective coatings to enhance corrosion resistance and extend the service life of the welded structures. The findings from this research offer comprehensive insights into the corrosion mechanisms in dissimilar alloys welding between AA5xxx-AA6xxx joints, providing practical guidance for optimizing welding processes. This paper aims to support the long-term performance of AA6xxx and AA5xxx aluminum alloy structures, particularly in critical industrial applications and environments demanding high corrosion resistance.

Abstract

Industri bambu memiliki peran penting dalam mendukung usaha kecil, namun proses pembelahan bambu secara manual masih menjadi kendala utama yang menghambat produktivitas dan berisiko terhadap keselamatan pekerja. Mesin pembelah bambu yang tersedia di pasaran saat ini cenderung mahal dan sulit dijangkau oleh produsen skala kecil, sehingga diperlukan alternatif yang lebih terjangkau dan efisien. Penelitian ini merancang dan mengembangkan mesin pembelah bambu yang ringkas untuk meningkatkan produktivitas dan keselamatan bagi usaha kecil. Mesin ini menggunakan motor berdaya 1 hp dan dilengkapi lima bilah pisau untuk membelah bambu selebar 3 cm menjadi empat bagian seragam berukuran 6x6x200 mm. Sistem transmisinya terdiri dari motor, reduktor, sproket dan rantai, serta pulley dan sabuk untuk memastikan operasi yang stabil dan andal. Solusi yang diusulkan ini menawarkan alternatif yang lebih hemat biaya dan efisien dibandingkan metode manual, sekaligus meningkatkan keselamatan kerja dan skalabilitas dalam pengolahan bambu. Studi ini menekankan pentingnya mekanisasi berbiaya rendah dalam mendorong inovasi dan keberlanjutan di industri bambu skala kecil.

Abstract

Effective solid waste management is essential to support industrial operations and environmental sustainability. PT ABC faces obstacles in the solid waste screening due to the less-than-optimal performance of the Vibration Sieve, especially in handling additive-lime and masterbatch-resin. This study aims to evaluate the performance of the tool before and after the redesign of the filter, as well as to determine the appropriate filter specifications for each type of waste. The method used is a quantitative approach through observation, measurement, and performance testing of the tool. The results show that a filter with a hole diameter of 6 mm is effective for additives and lime, while a 3 mm filter is effective for masterbatch and resin. After modification, the weight of the filtered waste increased from 3.26 kg to 16.97 kg. This modification has been shown to increase filtering effectivity and reduce waste
