Abstract

Quality control is intended to ensure that the products are in accordance with the predefined standards. PT. XYZ is a garment company that manufactures products with global target market. Hence, product quality assurance becomes an important issue for PT. XYZ. This research focuses on the Just Brand-MCJA216142 jacket product at the sewing work station on line-4 of PT. XYZ. Preliminary observations show that the number of reworked-products was experiencing an increasing trend. This study aims to determine whether the company has carried out quality control properly. Specifically, the research objectives are to identify the type and level of product defects, identify the factors causing product defects, and provide proper improvement suggestions to reduce the occurrence of product defects. This study applied DMAIC (Define–Measure–Analyze–Improve–Control) Six Sigma concept. The results showed that the quality of the Just Brand-MCJA216142 jacket product has exceeded the Indonesian industry average and is classified as the USA industry average. However, quality improvement is still needed since the products are targeted for the export market. Based on Pareto diagram at the Analyze stage, it was found that the most dominant defects occurred in the Just Brand-MCJA216142 jacket production process were broken threads and puckering. The frequency of occurrence for these two types of defect reaches 23% of the total 16 types of defects. The defects were caused by human, machine, material, method, and environmental factors. Recommendations for improvement at the Improve stage are based on root cause analysis of each causative factor that is identified using a fishbone diagram. This research results strengthen the previous related researches regarding the effectivity of DMAIC Six Sigma for analyzing quality control of products.

Abstract

Perusahaan perlu berhati-hati saat menentukan jumlah produksi botol minuman kemasan. Jumlah persediaan bahan baku dan permintaan menjadi faktor penting dalam menentukan jumlah produksi. Ketidakpastian jumlah permintaan produk minuman mengakibatkan jumlah produksi botol kemasan minuman kurang selaras dengan jumlah persediaan bahan baku minuman dan jumlah permintaan produksi botol kemasan. Adanya faktor ketidakpastian jumlah permintaan menjadikan pentingnya pemilihan metode peramalan yang tepat untuk memprediksi jumlah permintaan berdasarkan data historis. Penelitian ini bertujuan melakukan studi penentuan jumlah produksi botol kemasan minuman yang optimal dengan mempertimbangkan faktor ketidakpastian. Metode Fuzzy Time Series Markov Chain (FTSMC) adalah satu salah metode peramalan berbasis time series dan dapat diterapkan pada permasalahan ketidakpastian peramalan yang terjadi. Hasil peramalan, setelah melalui uji verifikasi menjadi input metode Fuzzy Inference System (FIS) untuk menentukan jumlah produksi botol minuman agar bersesuaian dengan jumlah permintaan dan jumlah bahan baku. Model FIS yang dibangun pada penelitian ini adalah Fuzzy Sugeno dan Fuzzy Mamdani. Untuk mengetahui metode yang memberikan hasil yang optimal pada permasalahan ini, kedua model yang dibangun tersebut dianalisis dengan membandingkan nilai Mean Absolute Percentage Error (MAPE). Hasil penelitian menunjukkan bahwa kedua model, yatu model FTSMC Fuzzy Mamdani dan model FTSMC Fuzzy Sugeno mampu memberikan solusi optimal.

Abstract

Thymus is one of the famous traditional foods in Karanganyar Regency, Central Java Province. Putri Timus is one of the Small Medium Enterprises in Karanganyar district that produces purple thymus. The product from Putri Timus has one specialty, namely the inside of the thymus contains Bligo fruit (Benincasa hispida) with various benefits. The method used in this program is to provide counseling and assistance regarding financial planning to MSME players to a simple but understandable application stage. The results of this community service program provide a simple solution to be careful in managing finances by considering several worst possibilities. Participants feel that they have a solution when they want to plan their finances both in the short and long term.

Abstract

This study aims to propose a lean analysis framework for waste management and to test it into the field case. The proposed framework was applied in a weaving process of a textile company in Indonesia. The seven classical Lean wastes were identified using value stream mapping (VSM). The result was then analyzed using the waste assessment model within which waste relationship matrix (WRM) and waste assessment questionnaire (WAQ) according to the answers of the head of weaving division studied. The major source of wastes was then determined utilizing the value stream analysis tool (VALSAT). In order to thoroughly examine the root cause of such dominant wastes and to propose corrective plans to minimize the waste, a fishbone diagram was used. As the main result, this study provides a lean waste analysis framework with examples to orientate managers about wastes. Particularly in our specific case, the results demonstrate that the waiting and defect become the most significant wastes that need to be treated. These findings allow a company to organize its activities and select tools or practices to optimize its efforts to create proper corrective plans in eliminating waste. In our study, the plans include periodic maintenance of weaving machines, clear division of tasks on the distribution of weft yarns, and eliminating unnecessary activities. In addition, it is mandatory to ensure the quality of warp yarns delivered to the weaving process as well as to perform a periodic calibration of equipment on weaving machines. This study advances in the theoretical and practical field by showing a structured way to incorporate lean analysis that can be adopted for any organization.

Abstract

The objective of this study is to model the technological, organizational, and environmental factors influencing the intention of food manufacturing Small Medium Enterprises (SMEs) to fulfill halal standard requirements. The research was conducted in Surakarta city in which halal-certified SMEs became the research object. Data were analyzed using Structural Equation Model-Partial Least Squares (SEM-PLS). Technological factors were measured by the perceived benefit and complexity of the halal procedure. An organizational factor was measured by SMEs awareness towards the halal standards. While the environmental factor was measured using external pressure. The result shows that the estimated model found support only for the role of perceived benefit of halal standard implementation in influencing the intention of food manufacturing SMEs to fulfill halal standard requirements. Other hypotheses were in the predicted direction but not statistically significant. A little less than half (R2 = 0.413) of the variability in the intention to fulfill halal standard requirements is explained by the four variables. The structural model in this study has a predictive relevance at a moderate level with a Q2 value of 0.208. Based on the findings of this study, it is expected that the government always explains the benefits of adopting a halal standard to the food manufacturing SMEs. Theoretically, this study makes a contribution to enriching the research literature regarding halal certification adoption factors among food manufacturing SMEs.
