Abstract

Fish is one of the species that is in high demand by consumers, including in Aceh. Fish can be obtained by catching from abundant nature. Problems in processing fish catches in Aceh, especially Langkak Village, Kuala Pesisir District, Nagan Raya Regency is a conventional post-capture processing method, which is drying using the heat of sunlight. In this condition, fish drying has several disadvantages, which are related to dependence on sunlight heat, cleanliness, freshness of fish, and selling points. For this reason, there needs to be a way to implement simple technology that uses a fish fogging machine. The purpose of carrying out this community service program is to provide practical applications of the fish fogging technique by providing soft skills to members of the fishing group in the Village of Langkak Village, Kuala Pesisir District, Nagan Raya Regency. The results of community service activities have been going well, starting with socialization activities or theory to the practice or application of fish fogging. The achievement of community service activities is the transfer of knowledge about making fish fogging machines and the practice and application of fish fogging directly by the fishermen of Langkak Village. In addition, other results are a manual guide on fish fogging to get the optimal fish fogging results. This activity received a good response from the fishermen of Langkak Village who participated in the activity, because it was considered very useful and became a facility to empower fishermen and residents in general.

Abstract

This research aims to conduct a comprehensive literature review on the application of dynamic system simulation as a decision-making tool. This research is motivated by the complexity of modern problems that require appropriate analytical tools to support better decision-making. The method used in this research is a systematic literature review by following structured steps to ensure that this research is comprehensive and unbiased. The results of this study indicate that dynamic systems are powerful and relevant analytical tools across sectors. With its ability to model dynamic interactions and simulate future scenarios, dynamic systems can help stakeholders make better decisions and achieve more sustainable results in facing complex challenges in the modern era. This study also identifies several challenges in the application of dynamic system simulation, such as lack of awareness of its benefits, lack of expertise in building and analyzing simulation models, as well as limited in-depth research on its application in various contexts. Therefore, further research is needed to address these challenges and improve the application of dynamic system simulation in decision making.

Abstract

Perkembangan teknologi Additive Manufacturing khususnya Fused Deposition Modeling (FDM) membuka peluang fabrikasi produk fungsional cepat, fleksibel, dan ekonomis tanpa cetakan konvensional. Penelitian ini bertujuan mengoptimalisasi desain dan parameter proses 3D printing FDM untuk Phone Hand Holder Multi Use berbahan PETG, mengevaluasi akurasi dimensi, kekasaran permukaan, dan kekuatan mekanik produk. Metode menggunakan pendekatan Design for Additive Manufacturing (DfAM) dengan siklus iteratif CAD-prototipe-evaluasi. Desain dibuat SolidWorks/AutoCAD, dicetak Prusa I3 MK3 dengan parameter optimal (layer height 0,2 mm, infill 20%, suhu nozzle 200°C, bed 80°C, speed 50 mm/s, wall 1,2 mm). Evaluasi meliputi pengukuran mikrometer digital (n=3), profilometer kekasaran (Ra), uji beban statis 350 g, dan uji siklus engsel 100x dengan analisis statistik paired t-test dan ANOVA. Hasil menunjukkan desain final (panjang 8 cm, tinggi 5,5 cm, lebar 2 cm, ketebalan 5 mm) mencapai akurasi dimensi 97,5% dengan deviasi ±0,2–0,5 mm dalam toleransi FDM. Kekasaran permukaan pre-finishing 13,6 µm turun ke 7,6 µm post-amplas (44,1% improvement, p=0,006 signifikan). Produk mampu menopang beban 350 g tanpa deformasi, engsel berfungsi 100 siklus tanpa kerusakan, confirm ketebalan 5 mm dan infill 20% memadai untuk penggunaan normal. Revisi desain meningkatkan stabilitas dan ergonomi tanpa mengurangi efisiensi material. Penelitian menunjukkan FDM-PETG optimal untuk phone holder fungsional presisi tinggi dengan finishing amplas wajib.

Abstract

Abstrak - Kapal berperan penting dalam menunjang aktivitas transportasi, perikanan, dan perdagangan sehingga kualitas kapal, baik pada proses pembangunan maupun reparasi, harus selalu dijaga. Penelitian ini bertujuan untuk menganalisis dan meningkatkan kualitas proses pengelasan pada reparasi kapal di Galangan Kapal Panggong, Aceh Barat, dengan menggunakan metode Six Sigma melalui pendekatan DMAIC (Define, Measure, Analyze, Improve, Control). Data dikumpulkan melalui observasi langsung, wawancara dengan teknisi dan manajer, serta dokumentasi cacat pada proses replating lambung kapal selama satu tahun pengamatan pada tujuh unit kapal dengan 123 sambungan yang diperiksa. Hasil identifikasi menemukan lima jenis cacat dominan, yaitu porositas (voids), retak las, undercut, incomplete fusion, dan spatter. Pada tahap pengukuran diperoleh rata-rata nilai Defect Per Million Opportunities (DPMO) sebesar 571.428,57 dengan level sigma 1,93, yang menunjukkan kemampuan proses masih rendah dan belum memenuhi standar kualitas industri. Analisis diagram sebab-akibat (fishbone) menunjukkan bahwa faktor dominan penyebab cacat berasal dari manusia (operator) dan metode kerja (SOP), diikuti oleh faktor mesin, material, dan lingkungan. Usulan perbaikan yang diberikan difokuskan pada peningkatan kompetensi operator melalui pelatihan, standarisasi prosedur pengelasan, serta perawatan dan kalibrasi mesin secara berkala. Penerapan usulan perbaikan tersebut diharapkan dapat menurunkan tingkat kecacatan, meningkatkan level sigma, dan menjaga keberlanjutan kualitas reparasi kapal di Galangan Kapal Panggong. Kata Kunci: Six Sigma; DMAIC; pengendalian kualitas; pengelasan; reparasi kapal; Abstract - Ships play an important role in supporting transportation, fishery, and trade activities, so ship quality must be maintained during both construction and repair processes. This study aims to analyze and improve the quality of the welding process in ship repair activities at Panggong Shipyard, West Aceh, using the Six Sigma method with the DMAIC (Define, Measure, Analyze, Improve, Control) approach. Data were collected through direct observation, interviews with technicians and managers, and documentation of defects during the hull replating process over one year of observation on seven ship units with 123 inspected joints. The results identified five dominant types of defects: porosity (voids), weld cracks, undercut, incomplete fusion, and spatter. In the measurement phase, the average Defects Per Million Opportunities (DPMO) was 571,428.57 with a sigma level of 1.93, indicating that process capability remains low and does not yet meet industrial quality standards. Fishbone diagram analysis revealed that the dominant causes of defects were human factors (operators) and work methods (SOP), followed by machine, material, and environmental factors. The proposed improvements focus on enhancing operator competence through training, standardizing welding procedures, and conducting regular machine maintenance and calibration. Implementation of these improvements is expected to reduce defect rates, increase the sigma level, and sustain the quality of ship repair at Panggong Shipyard. Keywords: Six Sigma; DMAIC; quality control; welding; ship repair;
