Abstract

This study investigated the effect of the coffee drying process using a coffee drying house on the moisture content, acidity, caffeine value, and flavour of Arabica coffee. An experimental method with a two-factor analysis of variance was used to evaluate significant differences between three different drying processes: Before Drying Process, Sun Drying Process, and Drying Process with Coffee Drying House. The results showed that sun-drying coffee with a coffee drying house produced lower moisture content, acidity, and caffeine value than the other drying processes. The flavour of Arabica coffee produced by this method was also considered sweeter by coffee export standards. Statistical analysis with Anova Block Subsampling, Anova 1 Factor Fixed Model, and Anova 2 Factor Factorial Design showed that the coffee drying process using coffee drying houses significantly affects the quality of arabica coffee. This study concludes that coffee drying houses can be an effective solution in improving the quality of Arabica coffee by controlling the moisture content, acidity, and caffeine value. The results of this study contribute to understanding the process of drying coffee beans and the factors that affect the final quality of the product. Therefore, this study provides an essential scientific basis for coffee farmers and the coffee processing industry to improve the quality of their coffee.

Abstract

Pada proses pengecatan alloy wheel, terdapat beberapa jenis defect yang sering terjadi, salah satunya adalah defect tosou butsu. Tujuan penelitian ini adalah untuk mengurangi tingkat defect (cacat) pada proses pengecatan alloy wheel di PT XYZ menggunakan pendekatan Lean and Green Six Sigma. Penelitian ini menerapkan pendekatan kuantitatif dalam metodologi penelitiannya. Pengumpulan data dilakukan melalui survei yang melibatkan observasi langsung dan dokumentasi. Setelah data terkumpul, data kemudian dianalisis. Hasil dari penelitian menemukan bahwa untuk mengurangi tingkat cacat pada proses pengecatan alloy wheel di PT XYZ, dapat diterapkan dan dijalankan mekanisme sistem pengendalian yang telah dikembangkan untuk memastikan bahwa setiap subproses dapat dijalankan dengan terkendali, mencegah terjadinya cacat berulang, serta untuk memastikan produk Alloy Wheel diproduksi sesuai standar yang ditetapkan.

Abstract

PT Terminal Petikemas Surabaya (TPS) has become one of the port services company has been trusted by various Indonesian and international companies in the management of international and domestic containers as well as various other loading and unloading services. PT TPS in providing international container management services is required to adjust its service level in accordance with international standards. Based on the Key Performance Indicator (KPI), the performance of PT TPS compared to some international ports in terms of Trund-Around Time (TRT), Gross Mover Per Hour (GMPH), and Berth Move Per Hour (BMPH) are still far behind with ports in UAE, Asia Pacific and India. The low performance of PT TPS based on the three indicators shows that the quality of service PT TPS still needs to be repaired. In this research, perception analysis and customer expectation with Service Quality (SERVQUAL) method to measure service quality of PT TPS. The gap between perception and customer expectation from Service Quality (SERVQUAL) is improved by Quality Function Deployment (QFD) method. And based on the two analysis, the preparation of strategies that should be applied by PT TPS to improve the quality of service. The results obtained show that all dimensions have satisfaction level “satisfied” which means that customers value the services provided by PT TPS is enough to meet expectations but still not maximal. Furthermore, Cartesius diagram analysis showed that there are 5 indicators that need improvement either immediately. The QFD analysis is performed to determine the recommended improvements on 5 indicators. Indicators that require top priority are indicators related to the competence of officers, especially administrative officers. So the management recommendation is to make Standard Operating Procedure (SOP) for each activity in port for administration officer
