Abstract

Pada proses pengeringan cengkeh di Kecamatan Munjungan masih sangat tradisional yaitu dengan cara dijemur dibawah sinar matahari, untuk menghasilkan kualitas yang bagus harus memerlukan waktu 3-4 hari dan apabila musim penghujan tiba maka di butuhkan waktu dalam kurun 5-7 hari dengan rata-rata waktu penjemuran 8-10 jam setiap hari tergantung terik matahari. Karena adanya kendala yaitu faktor iklim cuaca hujan atau mendung sehingga panas dari matahari yang dihasilkan tidak maksimal. Tidak hanya di Kecamatan Munjungan saja yang mengalami masalah tersebut, tentu pada daerah penghasil cengkeh lainnya juga mengalami masalah yang sama, karena masalah ini sangat berdampak terhadap kualitas dari cengkeh tersebut sehingga nilai harga jual dari cengkeh akan menurun. Untuk menyelesaikan masalah Mitra kelompok tani Lestari Trenggalek, Tim melakukan kegiatan dengan membantu membuat pengering, kemudian menyerahkan kepada Mitra, memberikan bimbingan perawatan dan penggunaan.  Pada akhir kegiatan Mitra memberikan kuesioner kepuasan dan 95% Mitra sangat setuju bahwa kegiatan yang dilaksanakan memberikan solusi atas masalah yang dihadapi mitra. Anggota tim yang terlibat dalam kegiatan aktif dalam memberikan bantuan. Frekuensi pendampingan yang dilakukan oleh tim sudah sesuai. Terjadi peningkatan kemandirian atau penambahan pengetahuan dan ketrampilan pada mitra. Secara keseluruhan mitra merasakan kepuasan atas kegiatan yang telah dilaksanakan.

Abstract

The continuous increase in population growth leads to a rising demand for electrical energy. PT. XYZ as a supplier of electrical energy, relies heavily on the reliability of its components to meet this demand. The frequency of failures in pulverizer machines is one of the factors that reduce production capacity. This study uses the FMEA method combined with LTA to determine the failure consequences caused by failure modes, resulting in appropriate maintenance actions for critical components. From the FMEA analysis, 10 failure modes were identified along with their causes and effects if failures occur. Based on the RPN value calculations, a critical value of 69.2 was obtained. Components with RPN values above the critical value that need prioritized maintenance are the classifier and grinding roller. In the maintenance planning stage, 7 failure modes are placed under time-directed (TD) maintenance, 2 failure modes under condition-directed (CD) maintenance, and 1 failure mode under finding failure (FF) maintenance.

Abstract

This research aims to analyze the performance and maintenance of the 21-ton/hour capacity boiler at PT XYZ through the application of the Overall Equipment Effectiveness (OEE) method. The boiler machine plays a crucial role in the production process, but it often experiences performance degradation that can disrupt the smooth operation of the company. OEE is used to measure how well the machine operates based on three main aspects: availability, performance, and quality. In addition, this study also uses the Six Big Losses analysis to identify the main causes of performance losses in the machine. The data used includes operational time, downtime, and the product quality of the boiler machine from January to December 2024. The analysis results show that the average OEE value of the boiler machine at PT XYZ reaches 93.49%, with an average availability value of 96.37%, performance value of 97.07%, and quality value of 100%. However, the main issues found are losses due to sudden breakdowns (breakdown losses) of 3.64% and reduced speed losses of 1.18%. The performance decline is mostly caused by issues with fuel and combustion. Therefore, it is recommended to conduct more routine fuel testing and improve the combustion process to reduce soot formation and maintain machine stability. This research is expected to assist PT XYZ in improving boiler machine performance and the smooth operation of production.

Abstract

This program was held aimed at improving the competency of technical drawing of vocational students in the Municipality of Kediri. Competence in this service consists of three aspects, namely affective, cognitive, and psychomotor. This program is carried out with a model of meeting in the classroom, giving theory, practicum, performance of making parts with image models and real object models. The improvement of students' abilities was measured using observation sheets of student activities to determine the improvement of the affective aspects of students, the pretest and posttest instruments to determine the increase in cognitive aspects of students, the worksheets of students to determine the improvement of psychomotor aspects. The first output of this program is to increase the ability of vocational students in the field of mechanical engineering with the help of computers using CAD-based software. The next output is a competency certificate that will be given to students in accordance with their competencies.

Abstract

Indonesia memiliki potensi produksi bawang merah karena tingginya konsumsi masyarakat. Melihat potensi ini, Bapak Surasa dari, Kota Kediri mendirikan usaha bawang merah goreng “Rizqi” sejak 2018. Bapak Surasa menjalankan usaha ini secara mandiri dan manual. Hanya bagian perajangan yang menggunakan alat kayu yang didorong. Selain itu, masalah lain yang ditemui adalah seiring berjalannya waktu jumlah pelanggan tidak bertambah karena pemasaran yang dilakukan masih sebatas menitipkan produk ke warung dan pedagang keliling. Hal ini karena bapak Surasa belum mencoba pemasaran online untuk memperluas jangkauan pemasaran. Oleh karena itu, dalam program pengabdian masyarakat ini, tim pengabdian menawarkan sejumlah solusi untuk mengatasi permasalahan tersebut antara lain dengan memanfaatkan teknologi mesin perajang untuk menambah kapasitas produksi dan memanfaatkan marketplace untuk memperluas jangkauan pemasaran. Metode pelaksanaan kegiatan pengabdian masyarakat dimulai dari pengadaan alat perajang dan dilanjutkan dengan pelatihan penggunaan alat. Kemudian dilanjutkan dengan membuatkan toko online di marketplace sekaligus pelatihan penggunaannya. Tim pengabdian juga melakukan pendampingan proses penggunaan alat dan pemasaran online. Hasil dari program pengabdian masyarakat ini adalah penerapan teknologi alat perajang sehingga UMKM bawang goreng Rizqi mampu menghasilkan enam kali lipat yakni 60kg setiap kali produksi. Di sisi lain, sampai akhir kegiatan pengabdian masyarakat dilaksanakan, UMKM bawang goreng Rizqi sudah mendapat 2 pesanan dari luar kota Kediri yakni Surabaya dan Lamongan masing-masing 5 pcs. Selanjutnya diharapkan UMKM bawang goreng Rizqi mampu memanfaatkan teknologi mesin perajang yang telah diberikan dan aktif memasarkan produk di marketplace yang telah dibuat.

Abstract

This paper presents a Computational Fluid Dynamics (CFD) simulation of a bread oven under steady-state conditions. An experimental measurement methodology was performed to determine the temperature distribution characteristics in the oven chamber. The CFD model simulation of the bread oven shows a homogeneous temperature distribution. Using a numerical model validated against experimental measurements, it is possible to highlight the temperature distribution pattern in the oven chamber and understand how the temperature spreads in a conductive air medium. Using data from experimental tests and CFD simulations, observations were made on temperature variations for 100, 110 and 120 in the oven chamber. The temperature for the oven chamber is distributed for a homogeneous distribution, with the temperature being 120 °C in both measurement and simulation. The lowest flow velocity is ~ 1.1 m/s, which is indicated by the light blue colour on the oven rack, and the highest velocity is ~ 4 m/s.
