Abstract

Based on the case study in the field, it was found that the casting product had surface defects in the form of cavities and was then repaired using a nickel electrode-based welding method. This repair was carried out to close the cavity defects so that a perfect casting shape was obtained. The material that has been welded has a different hardness from the base material, making it difficult to machining. This study aims to analyze the effect of welding on the ability of gray cast iron material that has been welded in terms of cutting tool wear and chip formation. The sample used was made of gray cast iron with a weld bead on its surface. Welding used a CIN-1 nickel electrode with the SMAW (shielded metal arc welding) welding method. Cutting was carried out using a conventional milling process using an HSS dovetail cutter. Observations were made through hardness testing on the base material, PMZ (partially melted zone), and weld metal which was continued with microstructure testing, wear measurement and chips formed. Based on the results of observations of FC 250 material that was welded on the base material, the microstructure formed was pearlite with graphite in the form of thin and long flakes. The microstructure in PMZ is formed by martensite and carbide, while the microstructure in weld metal consists of an austenite matrix with even distribution of graphite particles. The microstructure formed affects the hardness value of the material. From the observation, the hardness between weld metal and base material is not much different, namely 219 HV and 224 HV. The hardness in PMZ is 385 HV.

Abstract

Kesenian hadrah merupakan salah satu jenis kesenian Islam yang sudah membudaya di masyarakat, termasuk di masyarakat Desa Grenden Kecamatan Puger Kabupaten Jember. Sebelumnya di Desa Grenden sudah pernah ada kegiatan hadrah namun seiring waktu kegiatan tersebut terhenti. Hal ini sangat disayangkan karena tersedianya alat musik hadrah yang masih lengkap dan dalam kondisi bagus. Ditambah dengan banyaknya pemuda yang menetap di Desa Grenden, sehingga menjadi potensi untuk melaksanakan kembali kegiatan hadrah dengan memberdayakan para pemuda sebagai upaya untuk melestarikan kesenian hadrah. Tujuan dari pelaksanaan kegiatan pelestarian kesenian hadrah ini adalah untuk menghidupkan kembali kesenian hadrah yang hampir ditinggalkan kalangan pemuda, untuk menumbuhkan minat pada pemuda untuk mengikuti kegiatan hadrah, untuk memunculkan kebiasaan baru yang lebih positif bagi para pemuda dan untuk melestarikan kesenian hadrah. Metode yang digunakan dalam pelaksanaan kegiatan ini yaitu menggunakan strategi dan langkah- langkah yang telah disusun, strategi yang digunakan yaitu melakukan observasi di masyarakat, memanfaatkan potensi yang ada yaitu alat hadrah, melakukan sosialisasi di masyarakat, melibatkan stakeholder di desa yang memiliki keahlian di bidang hadrah, membentuk kelompok atau grup hadrah, memanfaatkan teknologi untuk promosi, dan memonitor dan mengevaluasi setiap tahapan yang dilaksanakan, dan langkah- langkah yang telah disusun yaitu koordinasi bersama stake holder, persiapan sarana prasarana kegiatan, pengorganisasian kelompok hadrah, pelaksanaan kegiatan, dan evaluasi kegiatan. Hasil dari pelaksanaan kegiatan ini adalah terbentuknya grup hadrah yang sudah diresmikan bersama perwakilan masyarakat dan kegiatan sholawatan rutin bersama masyarakat setiap satu bulan sekali. Program ini telah memberdayakan para pemuda di Desa Grenden melalui kegiatan pelestarian kesenian hadrah dan memberikan dampak yang positif bagi masyarakat Desa Grenden.
