Abstract

General Background Shrimp cracker production requires strict quality control, particularly in moisture content, which determines texture, shelf life, and defect occurrence. Specific Background In industrial practice, defects such as mold growth remain a critical issue due to suboptimal drying and process control conditions. Knowledge Gap Previous studies have not fully integrated process optimization and root cause identification to address both quality parameters and defect sources simultaneously. Aims This study aims to optimize drying parameters and identify root causes of defects using Response Surface Methodology (RSM) and Root Cause Analysis (RCA). Results The optimal conditions were obtained at a temperature of 70°C, drying time of 60 minutes, and thickness of 5 mm, producing a moisture content of 9.00% with a desirability value of 1.00. RCA findings indicate that mold defects are caused by high raw material moisture, inadequate storage conditions, and limited production supervision. Novelty This study integrates RSM-based parameter optimization with RCA-based defect analysis within a single framework. Implications The results provide practical recommendations for improving production control, reducing defects, and maintaining consistent product quality in shrimp cracker manufacturing. Keywords: Shrimp Cracker, Process Optimization, Moisture Content, Response Surface Methodology, Root Cause Analysis Key Findings Highlights Optimal drying parameters identified through statistical modeling approach Major defect source linked to raw material and process control conditions Integrated analytical framework supports systematic quality improvement

Abstract

In the era of the industrial revolution 4.0, we are in an age where the concept of an online system (cyber-physical system), the concept of the internet for everything or IoT (Internet of Things), and the concept of networking (networks). The creative economy must be the backbone of the Indonesian economy. In the era of the industrial revolution 4.0, we are in an age where the concept of an online system (cyber-physical system), the idea of the internet for everything or IoT (Internet of Things), and the idea of networking (networks). The creative economy must be the backbone of the Indonesian economy. This research aims to measure risk so that risk indicators in business processes in the Creative Economy will be known. The method of carrying out this research is by distributing questionnaires or questionnaires. Then do validation and reliability and calculate the indicators that have the highest level of risk. The results of this study are the demand risk variable with an indicator of the presence of business competitors with a value of 3.2 points which means that the risk is very high faced by business actors, and the raw material risk variable with an indicator of insufficient supply of raw materials with a value of 2.93 which means high risk faced by business actors.

Abstract

Majelis Tabligh Pimpinan Daerah Muhammadiyah (PDM) Sidoarjo memiliki peran strategis dalam menyelenggarakan kegiatan dakwah berbasis kelembagaan. Namun, efektivitas tata kelola kelembagaan Majelis Tabligh belum sepenuhnya optimal. Kegiatan pengabdian ini bertujuan untuk meningkatkan efektivitas kelembagaan Majelis Tabligh dengan pendekatan metode participatory appraissal (PRA) yang merupakan pendekatan dengan memahami kondisi organisasi secara prtisipatif untuk merumuskan perencanaan dan kebijakan dengan melibatkan entitas dalam suatu organisasi untuk mewujudkan program kerja yang telah di rencanakan. Dalam pelaksanaan kegiatan pengabdian kepada masyarakat (PkM) ini terdapat lima tahap, yaitu: observasi, persiapan kelengkapan, sosialisasi kegiatan dan urgensi tata kelola kelembagaan, workshop dan pendampingan, serta penyusunan strategi SWOC.  Hasil kegiatan menunjukkan peningkatan signifikan dalam kualitas tata kelola kelembagaan, ditandai dengan tersusunnya dokumen Renstra, panduan mutu, dokumen SOP dan instruksi kerja, serta format laporan kinerja divisi. Selain itu, terjadi peningkatan pemahaman dan kompetensi pengurus dalam hal manajemen kelembagaan. Dampak kegiatan juga mendukung capaian Indikator Kinerja Utama (IKU) perguruan tinggi, khususnya pada aspek kemitraan, kontribusi dosen, dan keterlibatan mahasiswa dalam kegiatan MBKM. Kegiatan ini membuktikan bahwa intervensi berbasis edukasi dan kolaborasi mampu mendorong transformasi kelembagaan berbasis nilai dakwah yang adaptif dan profesional.Kata kunci: efektivitas, majelis tabligh PDM Sidoarjo, tata kelola kelembagaan, sosialisasi, strategi SWOC

Abstract

General Background Human resources play a critical role in optimizing workforce performance to achieve business objectives, where organizational goals rely on operational activities executed by employees. Specific Background This study examines workforce challenges at PT. Karya Mitra Teknik Forklift Sidoarjo, where operational observations and interviews revealed that 37% of employees experienced competence-related issues and 40% faced work environment complaints affecting comfort and task execution. Knowledge Gap Although human resource capabilities dictate operational success, detailed assessments evaluating how specific competence dimensions and work environment conditions drive performance indicators utilizing combined analytical models require continuous investigation. Aims This study aims to determine whether competence and work environment affect employee performance and to identify top priority indicators for improvement. Results Utilizing Partial Least Square-Structural Equation Modeling (PLS-SEM) and Importance Performance Analysis (IPA), the findings indicate that competence and the work environment significantly affect employee performance with competency T-values of 2.54 and work environment T-values of 3.54, identifying competency indicator X1.1 and work environment indicator X2.2 as top priorities for improvement in quadrant I. Novelty This work integrates structural equation modeling with importance-performance matrices to pinpoint exact operational priorities for heavy equipment service personnel. Implications These findings establish that structured improvements in worker competencies and workplace spatial layouts are essential for maximizing task execution and organizational productivity. Highlights: Competence and work environment significantly affect employee performance, with statistical T-values exceeding critical thresholds. Priority improvements center on employee timeliness and the availability of supportive workspaces. Combined PLS-SEM and IPA methods effectively establish performance relationships and guide operational corrective actions. Keywords: Employee Performance, Partial Least Square-Structural Equation Modeling, Importance Performance Analysis, Competence, Work Environment
