Abstract

The effort to preserve batik is to maintain the continuity of batik production. Coloring process is one of the important processes in batik production. In addition to the dyeing technique, there is a “colet” technique in batik coloring process. Colet technique is considered an efficient technique in saving coloring dyes. The colet process is still carried out without standards and does not consider ergonomic aspects. This study aims to analyze the risk level of batik workers posture in colet technique coloring process. This research is an observational study with data analysis using the Rapid Entire Body Assessment (REBA) and Nordic Body Map (NBM). Based on the measurement, the risk level with the initial work posture has a score 9 and 7, which means the posture needs immediate corrective action to prevent occupational diseases. The implementation of Ergonomic “Colet” workbench is a way to improve work posture so the risk could be decreased, with score 4 both in standing and sitting working position.

Abstract

Inovasi teknologi di industri batik mengalami perkembangan dan diharapkan mampu mendorong akselerasi industrialisasi. Proses pewarnaan merupakan proses penting dalam menghasilkan batik dengan nilai estetika dan nilai ekonomis yang tinggi. Teknik pewarnaan yang dikaji dalam penelitian ini adalah teknik pewarnaan colet menggunakan zat warna Indigosol. Zat warna Indigosol merupakan salah satu zat warna sintetis yang menghasilkan warna pastel dan memerlukan penyinaran sinar matahari terik sebagai tahapan pra-oksidasi. Permasalahan muncul manakala cuaca mendung atau hujan. Proses pewarnaan menjadi tidak optimal atau bahkan tidak dapat dilakukan. Penelitian ini bertujuan memberikan solusi bagi permasalahan diskontinuitas produksi kain batik coletan dengan warna Indigosol. Rancang bangun meja colet menggunakan pendekatan Pahl dan Beitz. Berdasarkan pendekatan sistematis, dihasilkan rancangan meja colet dengan menggunakan teknologi ultraviolet sebagai pengganti sinar matahari yang digerakkan otomatis dengan mikrokontroler. Meja colet ini telah di-uji-cobakan secara fungsional dan memberikan hasil pewarnaan yang cerah disesuaikan dengan lamanya penyinaran. Abstract[The Design of Colet or Staining Process Workbench with Ultraviolet for Pre-Oxidation of Indigosol Dyes Using Pahl and Beitz Systematic Approach]  Technological innovation in the batik industry is experiencing developments that can encourage the acceleration of industrialization. The coloring process is an important process in producing batik with high aesthetic and economic value. The coloring process studied in this paper is the Colet staining technique using Indigosol dyes. Indigosol dye is a synthetic dye that produces soft colors and requires bright sunlight as a pre-oxidation stage. Problems arise when the weather is cloudy or rainy. The coloring process becomes not optimal or even impossible to produce. This study aims to provide a solution to the problem of discontinuity in the production of Coletan batik cloth with Indigosol dyes. The design of Colet Workbench using the Pahl and Beitz approach. Based on a systematic approach, a Colet Workbench design was produced using ultraviolet technology as a substitute for the sunlight which is driven automatically by a microcontroller. The Colet workbench has been tested functionally and provides bright staining results according to the length of irradiation.Keywords: engineering design; pencoletan; indigosol; Pahl and Beitz

Abstract

Lembaga Amil Zakat (LAZ) Udinus merupakan suatu lembaga yang berada di bawah organisasi Pusat Aktivitas Muslim (PAM) Udinus. LAZ mempunyai kegiatan yang sudah bertahun tahun dilaksanakan yaitu membina anak – anak asuh yang mana mereka mendapatkan bantuan untuk membayar sekolah setiap bulannya. Akan tetapi mereka harus mengikuti kegiatan yang wajib yang harus dilaksanakan yaitu mengikuti kajian setiap minggunya. Pada kegiatan tersebut mereka diberikan ilmu – ilmu yang berkaitan dengan ajaran Islam. Salah satunya adalah memberikan pendampingan dan pengarahan tentang adab menuntut ilmu dalam Islam. Hal ini dikarenakan semua anak – anak LAZ adalah peserta didik SD, SMP, SMA/K dan Pondok Pesantren. Namun untuk yang di Pondok Pesantren tidak dilakukan pendampingan. Dengan adanya pendampingan untuk anak SD, SMP, SMA/K ini, diharapkan mereka menjalankan adab menuntut ilmu yang sesuai dengan ajaran Islam. Selain harus sesuai dengan ajaran Islam, mereka juga diberikan pengertian tentang ilmu dan teknologi. Teknologi sangat berpengaruh terhadap ilmu yang dijalankan pada masa sekarang. Untuk itu mereka diberikan cara untuk menyikapi teknologi jaman sekarang dengan adab menuntut ilmu menurut ajaran Islam. Dengan pendampingan ini, diharapkan anak – anak Islam bisa menuntut ilmu menurut perkembangan jaman yang tidak menyimpang dengan ajaran Islam. Menuntut ilmu di sini harus didasari dengan rasa tanggung jawab yang bisa membentuk karakter positif bagi anak – anak LAZ.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) in the garment sector frequently face production planning challenges arising from demand fluctuations, limited raw materials, capacity constraints, and inadequate inventory management, which ultimately increase operational costs. This study proposes an integrated forecasting–optimization framework combining single exponential smoothing (SES) and integer linear programming (ILP) to determine the optimal multi-product production combination that minimizes total production and inventory costs in a garment MSME in Jiddah. Historical production data of five products over 12 periods were used to forecast demand, which subsequently served as input for the optimization model. The model was solved using LINGO 21 under three scenarios: (1) considering safety stock and capacity constraints, (2) excluding safety stock, and (3) excluding production capacity constraints. The forecasting results produced an average mean absolute percentage error (MAPE) of 5.79%, indicating highly accurate demand estimates. The optimization results showed that Model 2 generated the lowest total cost of IDR 277,755,500 with a production quantity of 8,157 units and no ending inventory. However, Model 1 was identified as the most appropriate scenario for implementation because it maintained a safety stock of 200 units per product while satisfying production and raw material constraints, resulting in a total production of 9,157 units and a total cost of IDR 312,878,500. Furthermore, Model 3 produced the same solution as Model 1, indicating that production capacity was not a binding constraint under the existing operating conditions. Sensitivity analysis confirmed that the safety stock is a critical factor influencing production decisions, inventory levels, and total costs. Theoretically, this study extends conventional ILP applications by integrating demand forecasting and inventory policy considerations into a single decision-making framework for data-limited MSMEs. Managerially, the proposed model provides practical decision support for balancing cost efficiency and inventory security in multi-product production planning.
