Abstract

Garment industry often faces many problems such as low productivity, long lead time production, high product rework and rejection, improper line balancing, and inflexible style running changeover. The aim of this research is to implement one of the lean concept tools namely one piece flow. This study focuses on Sewing Department of Man Shirt Unit in a Garment Company in Central Java, Indonesia. The study of this paper includes the description of garment manufacturing process flow and comparison between the batch production system and one-piece flow system. The performance criteria used in this study is the total processing time, the basic pitch time, the production targets and the throughput time. The time study is used as the measurement method to determine the cycle time and throughput. From the analysis, one piece flow system performs better in term of total processing time, the basic pitch time and the throughput time and the target achievement than batch production system. The total processing time and pitch time reduced by 6.42 % and 0.385% respectively. The daily target quantity increased by 8.609% and tThe troughput time of 1 piece of good garment in assembly line reduced from 3.35 hour to 0.915 hour.

Abstract

Baby diaper waste management is becoming an increasingly pressing environmental issue due to the high use of disposable diapers in the community. The lack of waste management infrastructure and low environmental awareness are the main obstacles in increasing public participation in the collection of baby diaper waste. This study aims to identify the factors that influence the level of consumer willingness to collect baby diaper waste and determine the expected compensation expected by consumers. Multiple ordinal regression and Contingent Valuation Method (CVM) were used to achieve these objectives. The results of multiple ordinal regression analysis show that several independent variables have a significant influence on community participation in baby diaper waste management, including Environmental Awareness (X1), Infrastructure Availability (X2), Knowledge and Education (X3), Economy (X4), Policy and Regulation (X6), Ease of Access and Facilities (X7), and Culture and Social Norms (X8). Meanwhile, Community Involvement (X5) did not show a significant effect. Of these variables, Infrastructure Availability (X2), Culture and Social Norms (X8), and Policy and Regulation (X6) show the most significant influence. Based on the CVM results, the average expected compensation for community participation is Rp1,250 per kilogram of dry diaper waste. These findings suggest the importance of improving waste management infrastructure as well as supportive policies to encourage community participation. In addition, attractive economic incentives need to be implemented to strengthen community involvement in the collection of baby diaper waste. This study provides insights for stakeholders in formulating policies that support the development of effective and sustainable community participation-based waste management programs.

Abstract

In this era, the development ofptechnology has encouraged many companies to produce creative, innovative products, and strive to generate higher competitive value for their companies. determining the delivery route has several objectives to be achieved, for example to minimize shipping costs and time or distance traveled. The Saving Matrix methodlis a methodlused in determining product distribution routes to the marketinglarea by determininglthe distribution routes that must be passedlandlthe numberloflvehicles basedlon the capacity oflthe vehicle in orderlto obtain the shortest route and minimum transportation costs. PT. XYZ is a company engagedpin the sale of various needs for agriculture such as fertilizers, seeds and chemical drugs for agricultural production where every day must fulfill every order from customers. The purpose oflthis research is the need for a distribution system that can facilitate the delivery of time efficiency, precise in delivery, and provide the fastest route in the delivery of customer orders. Data collection is done by interviewin and observing the company. The data material was taken from October to November 2020. The results oflthe study obtained that the total distance traveled on the new route was 193.4 km and the total transportation cost was Idr.930,000, so that the method used can minimize the distance and costs traveled.

Email: raisaribatul9@gmail.com ABSTRAK Universitas Islam Batik (UNIBA) Surakarta adalah salah satu perguruan tinggi swasta yang berbasis Islam. Tindak lanjut dari implementasi Visi UNIBA yaitu menjadi Universitas yang akhlakul karimah dan memiliki komitmen pada risalah islamiyah, maka perlu diadakannya pembinaan dan pembimbingan baca Al-Quran yang baik, yang akhirnya mahasiswa mampu menerapkan nilai-nilai Islami dalam masyarakat dan dalam dunia kerja. Tujuan dilaksanakannya kegiatan ini untuk membimbing mahasiswa agar lebih lancar dan paham dalam membaca Al-Quran, serta membentuk kepribadian dan upgrade keimanan para mahasiswa UNIBA. Metode yang digunakan antara lain : melakukan survei online untuk pendataan, melakukan tes individu, pengelompokan peserta berdasarkan kemampuan, dan pelaksanaan pembimbingan baca Al-Quran rutin. Luaran dari kegiatan ini mahasiswa mendapatkan program pembinaan, sertifikat yang digunakan sebagai syarat kelulusan serta laporan kegiatan. Kesimpulan dari kegiatan pengabdian ini adalah mayoritas mahasiswa UNIBA Surakarta (76%) belum mahir dalam membaca Al-Quran, apalagi pengetahuan terhadap ilmu Tajwid. Kegiatan ini diikuti oleh seluruh mahasiswa jenjang S1 seluruh Program Studi di UNIBA. Diharapkan dari kegiatan ini mahasiswa dapat merasakan manfaat membersihkan penyakit hati (sombong, riya’, tamak dan dengki) serta mencerdaskan otak, karena aktivitas melihat, mendengar dan membaca Al-Quran.

Abstract

Indonesia memiliki tanggung jawab besar untuk mempertahaankan dan melestarikan budaya batik karena batik merupakan warisan dunia asli Indonesia. Hal ini berlaku sejak UNESCO menetapkan batik sebagai Masterpieces of the Oral and Intangible Heritage of Humanity tahun 2009. Upaya melestarikan budaya batik dilakukan dengan kegiatan presentasi dan workshop tingkat internasional untuk pertukaran budaya batik. Teknik proses membatik telah berkembang seiring perkembangan teknologi, sehingga jika negara Indonesia tidak aktif terlibat maka akan tertinggal dari negara lain. Workshop dan presentasi diikuti oleh empat negara sebagai narasumber presentasi dan workshop. Tim Universitas Islam Batik menjadi delegasi dari Indonesia yang dipercaya untuk menyampaikan materi dalam presentasi dan workshop. Presentasi dan workshop dilaksanakan dalam acara “The 1st International Conference Batik Creative Workshop and Presentation “Culture Heritage : Batik Asean Mutual Cultural” di Phuket Thailand. Hasil kegiatan ini adalah: 1) semua negara sepakat bahwa budaya batik harus dilestarikan 2) Perlu adanya inovasi khususnya dalam proses membatik sehingga proses lebih efisien 3) Inovasi tetap harus menjaga nilai batik sebagai warisan budaya 4) Setiap negara memiliki ragam motif yang menjadi ciri khas 5) Terdapat perbedaan teknik, alat dan bahan untuk proses membatik dari empat negara.

Abstract

The growing issue of disposable baby diaper waste requires an effective collection model to support sustainable waste management. This study designs a community-based collection model using the Analytical Hierarchy Process (AHP) method to identify the most effective approach. Three models are evaluated: Model 1 (Community-Based Diaper Bank), Model 2 (Scheduled Diaper Pick-Up Program), and Model 3 (Diaper Collection Points at Public Facilities). Results show Model 1 is the most effective, with the highest Global Priority score of 0.415, due to its contributions to reducing environmental impact, raising public awareness, and incentivizing participation. Model 2 and Model 3 follow with scores of 0.353 and 0.261. The environmental criterion holds the highest weight (0.504), emphasizing its importance. These findings suggest that community-based models can enhance waste collection efficiency and support sustainability. The results can inform policy development and help guide future research on sustainable waste management practices.
