Abstract

Perikanan memegang peranan penting di Indonesia. Dari perikanan ini akan dihasilkan hasil samping berupa udang-udang kecil. Jika tidak ditangani dengan baik, udang ini bisa menjadi masalah limbah serius dari bau amis. Salah satu cara untuk mengatasinya adalah dengan memanfaatkannya sebagai kerupuk. Namun, penjualan kerupuk ini menghadapi beberapa masalah seperti penjualan yang rendah, dan terkadang tidak ada konsumen atau pasar. Di sisi lain, jika ditangani dengan baik dan memenuhi kebutuhan pelanggan, dapat menjadi solusi dari produk sampingan ini. Oleh karena itu, penelitian ini dilakukan untuk mengetahui preferensi konsumen terhadap produk ini. Penelitian ini dilakukan dengan menggunakan kuesioner kerupuk udang buatan ibu rumah tangga di RT 11 Kabupaten PPU Kalimantan Timur. Kuesioner ini digunakan untuk mendapatkan tingkat atribut dan untuk menganalisis tingkat kepentingan dengan menggunakan metode analisis konjoin. Hasil analisis menunjukkan bahwa untuk kerupuk udang, atribut kesesuaian memegang peranan penting. Berdasarkan tingkat atribut, konsumen lebih menyukai harga yang terjangkau, kualitas bahan utama yang baik, kerupuk dikonsumsi sebagai pelengkap makanan utama, kerupuk tidak berbau amis, memiliki label halal MUI, mudah didapatkan, dan kemasan yang rapi.

Abstract

The turning process in manufacturing is used as the formation of cylindrical components, threads and drilling. ST41 steel has the ability to form, weld and treat, so it is used as a material for tools and automotive components. Insert tools with long life (live time), resistance to wear and high temperatures are better than conventional tools, making the type of insert tool used for various cutting processes. The quality of turning is determined by the selection of cutting parameters that are appropriate to the type of material being cut and the tool used. Lathe parameters are feed rate, cutting speed, deep cut. Feed rate parameters affect process time, surface roughness and tool wear. The use of excessive feed rate causes surface roughness outside tolerance and large tool wear. Therefore, research on ST 41 steel with insert tools to obtain optimal parameters is needed. Research using the experimental study method aims to analyze the effect of tool wear values ​​on changes in feed motion and surface roughness. Turning of ST41 steel on a GUT C0636D X 1000 lathe, CCMT 060204 insert tool, 0.6mm depth cut, 300 rpm cutting speed and feed rate variation of 0.1620, 0.3250, 0.8120 mm/rev. The results of the study measured the tool wear value increasing against feed rate and surface roughness. The highest tool wear value is 0.021 grams, namely with a feed rate variation of 0.8120 mm/rev, a surface roughness of 8.961 μm is obtained. The lowest tool wear value is 0.005 grams, namely with a feed rate of 0.6120 mm/rev, a surface roughness of 5.300 μm is obtained.

Abstract

The cutting quality of a lathe is influenced by various cutting parameters. Spindle speed is the main parameter that influences the level of surface roughness and tool wear. The research aims to understand the impact of using a VNMG 160408-MA type insert tool in cutting AISI 4340 steel on surface roughness and tool wear values. The spindle speeds used are 190 rpm, 300 rpm, 460 rpm, 755 rpm, 1,255 rpm, feed rate 0.209 mm/rev, and cutting depth 0.5 mm. Experimental methods were used in the research. The research results showed that variations in spindle speed had a significant effect on surface roughness, tool wear and cutting temperature as evidenced by the P-Value < 0.05. At a value at a spindle speed of 190 rpm, the surface roughness value was 6.195 μm, tool wear was 0.002 grams and tool temperature was 48.178 °C. The spindle speed value of 1,255 rpm measured a surface roughness value of 1.971 μm, tool wear of 0.053 grams, and tool temperature of 90.389 °C.

Abstract

DAMIU is a microenterprise that has had significant growth in East Balikpapan, particularly in the Lamaru region. The necessity of water is paramount for humans, as it is a vital component of the body, supports essential activities, and is crucial for general health. Socialization occurs in person in the Lamaru Balikpapan Timur Health Center auditorium. Customers requiring water refills predominantly consist of stalls, private residences, and projects, with a general preference for delivery over self-collection at the depot. The distribution process employs a pick-up vehicle with a capacity of 60-70 gallons each trip. The survey results indicated a production of 3,800 liters per day for one vehicle. Among the 10 depots, 3 DAMIUs utilize one vehicle, while 7 DAMIUs employ 2 to 3 vehicles. The water supply utilized comprises 80% PDAM from 10 DAMIUs. Customers who are frequently disoriented and negligent impede the delivery procedure. Map Marker accurately identifies the client's location by interfacing with Google Maps and allows the input of images of residences, stalls, or locations, as well as customer telephone numbers. Participants from the socialization group rated it 6 out of 10, exhibiting complete curiosity about utilizing the application. DAMIU owners in the East Balikpapan area have achieved income stability and mitigated staff fraud through the utilization of the Map Marker application, presenting a significant advantage for them.

Abstract

A36 steel as raw material for heavy equipment attachments, such as blades and buckets. Gas Metal Arc Welding (GMAW) and Flux-Cored Arc Welding (FCAW) are used for the connection. High heat input and weld metal protection mechanisms are suitable for joining thick plates, however, in the field, malfunctions were found due to damage to the weld joint. To overcome this problem, research was carried out on two welding techniques to obtain optimal joint strength values. The research uses GMAW, FCAW and combination welding to join A36 steel with a V-beam angle of 60°. On the welding results, Magnetic Particle Inspection (MPI) and bending tests will be carried out. MPI testing states combination welding meets the requirements of the AWS1015 standard. The highest bending strength in FCAW welding was 160,419 MPa and the lowest in GMAW was 71,724 MPa, while combination welding was 113,312 MPa. The difference in value is influenced by the phases formed from each welding method visible in the microphotographs in the weld metal, HAZ and base metal areas.
