Abstract

One of the company's efforts in implementing the commitment to customer satisfaction is carried out through continuous improvement activities. All indicators are evaluated to determine the level of quality stability against process variations that will impact non-compliance with predetermined product specifications. One of the quality problems found in the tire manufacture industry is the out-percentage of tire uniformity, which suddenly increases, one of which is the value of static balance. This study analyses the process variation factors that occur to take corrective and preventive actions through a series of Root Cause Analysis (RCA), Fault Tree Analysis (FTA), and Failure Mode and Effect Analysis (FMEA). Refers to the analysis result, it was found that there was a problem with the rubber film gauge variation at the manufacturing step of the steel breaker, one of the material components in the tire construction. Two main factors cause rubber film thickness variation: rubber sticky with roll calendar, Radial Run Out (RRO) Roll Calendar out standard, and viscosity compound variation with 12 root problems found. The results of the improvements that have been made can effectively improve rubber film thickness variation, increase the Cpk level of steel breaker material from 0.82 to 1.91 and reduce the out percentage ratio of static balance by 54.65%.

Abstract

The balanced scorecard is a formal management technique for developing, implementing, and managing business strategies. It isn't easy to ascertain the technique's success. Most of the literature on its implementation is put out by those with a vested interest in its success as a commercial product. Much has been written about barriers to strategy implementation but not specifically to implementing a balanced scorecard. The literature review in this paper shows that studies on BSC implementation in corporate organizations focus on improving organizational performance, assisting in decision making, assisting in component selection, evaluating production and learning and sustainable growth. This paper provides benefits for further research to add to the literature and understanding of the implementation of the Balanced Scorecard in any organization.

Abstract

In February 2020, the Indonesian Ministry of Cooperatives and SMEs noted that in the last four years, 81,686 cooperatives were dissolved, leaving 123,048 active cooperatives. This case is a huge challenge for the government to overcome.  Indonesian Internet Service Providers Association (APJII) stated that the number of internet users in Indonesia reached 196.7 million in the middle of 2020. Meanwhile, data from Google & Temasek showed purchasing products via e-Commerce in Indonesia reached US$ 10.9 billion in 2017 and continuously increased in 2020. Most cooperatives in Indonesia run business conventionally with manual transactions, limited time, traditional logistics, and conventional membership administration. Nowadays, the institution with tens of thousands of members no longer effectively runs cooperative conventionally in a disruptive era. A conventional cooperative at a private university in Jakarta was observed in the study. There are tens of thousands of students and staff at the university. Three research questions arise, such as what can not be adequately solved in a traditional cooperative, what tools are used in digital cooperatives, and what shape can be used in the digital cooperative system model to solve issues. This study proposes a framework model in developing a digital cooperative to accommodate a huge amount of membership and enhance business scope. The research identified technology needed to overcome matters cannot be dealt with in a conventional cooperative. It provided a  digital cooperative frameworks model that impacts value creation, value capture, and value delivery, especially in higher education.

Abstract

Along with the increasing market of plastic packaging products resulting from the injection process and the rapid development of existing technology, we need a strategy to be able to continue to meet the customer’s needs and to be able to compete in the industry. One of the strategies that may be employed is Lean. Lean is a concept aimed at eliminating existing waste. One of the implementations of Lean’s concept is the SMED (Single Minute Exchange of Dies) concept. SMED is a concept aimed at reducing the changeover time, so the eliminated time can be used in the production process. P.T. BIL is one of the companies engaged in the production of plastic packaging with an injection process. Problems occurring at P.T. BIL was the absence of a measurement process for changeover time. The Operation Analysis Chart concept was used to analyze the carried-out activities. To optimize activities employing the SMED concept, Analytical Cards were used so that the change over time can be reduced. The 5S concept was applied to support the SMED concept, so the waste in the work area could be eliminated. By implementing the SMED concept, we reduced 18% of the change over time.

Abstract

FMEA (Failure Mode Effect Analysis)  adalah metode yang digunakan dalam mengidentifikasi kemungkinan  kegagalan  pada proses, fungsi  dan design produk  sehingga diketahui penyebab dan  akibatnya  untuk meningkatkan mutu dan reliabilitas produk. Kegagalan proses insulasi pada proses produksi AW (Automotive Wire) mengganggu kinerja produksi PT JLC.  FMEA  digunakan untuk mengidentifikasi dan mencegah potensi kegagalan proses insulasi pada produksi produk AW (Automotive Wire) di PT JLC . FMEA diulas oleh banyak riset sebagai metode efektif dan dijadikan format standar yang digunakan oleh industri otomotif dalam membuat daftar potensi kegagalan sehingga dapat mengetahui penyebab, dampak dan tindakan pencegahan dalam mengatasinya. FMEA menyediakan metode dalam membuat daftar potensi kegagalan produk AW (Automotive Ware) melalui penilaian kuantitatif dengan kriteria  tiga aspek yaitu Tingkat kemungkinan frekwensi terjadi kegagalan (O=Occurence), Tingkat resiko akibat kegagalan (S=Severity) dan Tingkat kemungkinan bisa dideteksi (D=Detection). Dari hasil perhitungan dan analisis FMEA maka dihasilkan daftar urutan prioritas potensi kegagalan  proses insulasi melalui perhitungan pada tiga aspek Occurence (O), Severity (S) dan Detection (D) disertai kemungkinan penyebab, dampak dan solusinya. Dua potensi kegagalan terbesar adalah Ketidaksesuaian warna (terlau tua atau muda), marking tidak tercetak jelas dan permukaan insulasi yang kasar. FMEA  mampu mengidentifikasi penyebab, dampak dan  pencegahan untuk mengantisipasi kegagalan tersebut.

Abstract

Pricing products is an important factor to penetrate the Indonesian market successfully. Since Indonesia’s medical device products market has more than 90% import, local production companies must be competitive in price. The current pricing approach relies on the cost of sold goods, profit margin, and cost. Hence, a new pricing model is needed. The price from the new model must be better than the current price from the conventional pricing approach. The research aimed to formulate a pricing model for local medical device products that the market could accept and provide a framework model in local production pricing using investment feasibility analysis. The research used mathematical models, engineering economics, and pricing frameworks to optimize product prices from a local company (PT Enesser Mitra Berkah). The studied object was the domestic production of Anesthesia A8500. The research has several findings. First, the Break-Even Point (BEP) (X2) is an alternative standpoint to determine the price in a local production investment for medical device products. Second, the production company can consider the market price (X3). The research develops a simple mathematical model of X3 > Y2 = X2 + Ct > X1 (Y2 = new price, X1= cost of sold goods, Ct = profit and cost). The result provides the pricing framework model as a new approach for developing a medical device product price when the company initiates new local production.

Abstract

Third-party laboratories are laboratories that provide analytical services as quality control of an item to be marketed. In its activities, sometimes the results of the analysis produced by the laboratory are not all acceptable because there are analysis results that do not meet the test quality specifications. The purpose of this study is to improve the defect rate on the test results using QC tools and FMEA methods. The findings in this study identify the main root causes are the errors of analysts when doing testing, there are no standard procedures for instrument maintenance, and lack of supervision. The proposed improvements given are personnel training, working instruction for instrument maintenance, logbook for record the activity and tighter supervision. After repairs, the defect rate in the test results can be reduced from 5.72% to 1.02%. Keyword: FMEA, Laboratory, Re-testing, Textiles.
