Abstract

CNP channel steel, commonly referred to as lightweight C-channel steel, is a steel bar characterized by its 'C' shaped cross-section, produced through the cooling process of steel plates or strips. This type of steel holds significant importance in construction, as the strength of its connections plays a critical role in its load-bearing capacity. In this research, a low carbon steel, specifically CNP channel steel with a 3 mm thickness, was selected as the base material. The welding parameters included varying welding currents (70 A, 80 A, and 90 A), welding speeds (2 mm/s, 3 mm/s, and 4 mm/s), and different cooling media (NaCl solution, mineral water, and lubricant). Following the welding process, tensile tests were conducted to evaluate the mechanical properties of the welded joints. The Taguchi Orthogonal Array L9(33) method, comprising 9 experiments with 3 replications, was utilized to determine the optimal combination of parameters. The results show that the highest tensile strength recorded was 38.75 N/mm² in the combination of a welding current of 80 A, welding speed of 4 mm/s, and cooling media using mineral water. On the other hand, the lowest tensile strength recorded was 12.70 N/mm² (70 A, 3 mm/s, NaCl solution). The welded joints indicated that 16 specimens experienced brittle fractures, while 11 specimens exhibited ductile fractures. Brittle fractures mainly occurred at the welding joints, while ductile fractures were found in the base material. Based on the Taguchi method, the optimal parameter values were identified a welding current of 90 A, a welding speed of 4 mm/s, and using lubricant as the cooling media which welding current holds the highest percentage of contribution.

Abstract

This study aims to investigate the influence of the conventional lathe machine's cutting parameters in the turning process of ST-42 steel material  on surface roughness and tool wear by employing an HSS tool. The examined cutting parameters encompass the spindle speed and the depth of cut, while maintaining a consistent feed rate. Each cutting parameter was evaluated at three different levels, spindle speed of 330 rpm, 360 rpm, and 500 rpm, and depth of cut 0.2 mm, 0.5 mm, and 1 mm, all with a uniform feed rate of 0.3 mm/minute. The findings of this research demonstrate that alterations in spindle speed and depth of cut exert a discernible influence on both surface roughness and tool wear. Elevated spindle speeds are associated with reduced surface roughness, albeit at the expense of increased tool wear. Conversely, deeper depth of cut correspond to heightened surface roughness, yet lead to decreased tool wear, aiming to achieve a uniform final diameter of the workpiece. By synergistic manipulation of these two parameters, the most favorable outcome in terms of surface roughness and tool wear can be identified. The lowest surface roughness was 4.42 μm, found at a spindle speed of 500 rpm coupled with the depth of cut of 0.2 mm. Meanwhile, the least amount of tool wear, quantified at 0.07 mm, was achieved at a spindle rotation speed of 330 rpm along with a cutting depth of 1 mm. The application of ANOVA analysis substantiates the statistical significance of both parameters, affirming their pivotal role in influencing surface roughness and tool wear.

Abstract

Mangroves have many benefits. However, not many people know and understand the benefits of mangroves. Therefore, this service aims to provide education and plant mangroves in Taddan Village, Sampang. The service carried out in July - November 2023 in Taddan Village, Camplong District, Sampang Regency. The tools and materials used in this service include mangroves, gloves, raffia rope and stakes. Mangrove education was carried out at the Taddan Village Hall, Sampang involving the Taddan Village community. Mangrove planting was carried out twice involving several parties including Forkopimcam, Camplong District, TNI-Polri personnel, Disaster Risk Reduction Forum (FPRB) Sampang Regency, Taddan Mangrove Conversation (TMC) Sampang, students of Trunojoyo Madura University (UTM) Bangkalan, and members of Saka Bhayangkara Sampang Quarter. This activity ran smoothly and successfully. The type of mangrove planted is Rhizopora stylosa with a total of 4000 seeds.It is hoped that planting mangrove tree seedlings can protect the coastline of Taddan Village from erosion and sea water abrasion while also protecting marine biota.

Abstract

Halal tourism and digital entrepreneurship require an appropriate strategic management approach as an effort to create a sustainable halal tourism and digital entrepreneurial world. Strategic planning for a halal tourism destination is a key word in increasing the competitiveness of the halal tourism sector and the need for digitalization in developing this sector. The aim of this research is to analyze the potential of halal tourism in relation to digital entrepreneurship, as well as determine the implementation of existing and potential strategic management and determine the implementation of the quality of planning, implementation, assessment and follow-up strategic planning which is in accordance with the standards and quality of sustainable halal tourism in relation to student digital entrepreneurship. This research is a type of qualitative research. The research results show that appropriate strategic management can improve existing, potential and sustainable halal tourism supported by digital entrepreneurship.

Abstract

Ekowisata Mangrove Labuhan memiliki daya tarik pada aspek konservasi ekologi, tetapi pengembangannya masih belum optimal. Tantangan utama terdapat pada sektor konservasi mangrove yang didasarkan pada jumlah tanaman yang masih terbatas, sehingga mengurangi potensi ekologi kawasan. Selain itu, sektor pemeliharaan aset menghadapi kendala berupa kondisi fasilitas penerangan yang minim serta jalur tracking yang rusak, sehingga memerlukan perbaikan untuk meningkatkan kenyamanan dan daya tarik wisatawan. Atas dasar permasalahan tersebut, maka pengabdian ini bertujuan untuk melakukan pemberdayaan masyarakat melalui mitra Kelompok Sadar Wisata Payung Kuning Labuhan, Bangkalan. Metode yang digunakan yaitu pendekatan partisipasif dan kerja sama dengan komunitas lokal melalaui berbagai betuk kegiatan seperti sosialisasi (peningkatan kapasitas masyarakat), penanaman mangrove bersama, aksi sisir pantai, dan peremajaan fasilitas ekowisata mangrove. Hasil penanaman mangrove yang berhasil tumbuh akan menjadi aset penting dalam keberlangsungan hidup ekosistem serta ekowisata. Pengabdian ini telah mampu meningkatkan konservasi keanekaragaman hayati mangrove melalui penanaman 1.000 bibit mangrove, menjaga kelestarian alam melalui aksi sisir pantai dan mempromosikan praktik berkelanjutan melalui perbaikan di ekowisata mangrove Labuhan. Sosialisasi mengenai peran dan manfaat mangrove diharapkan mampu memberikan pemahaman baru tentang pentingnya mangrove di ekosistem pantai, serta menjaga kebersihan pantai dan mangrove. Peremajaan fasilitas wisata akan memberikan timbal balik keuntungan bagi mitra untuk beberapa tahun ke depan.
