Abstract

Indonesia is a country with a majority Muslim population. Therefore, Indonesian consumers have to be more thorough in assuring halal guarantees. One of some identities as a Muslim is consuming halal products. Various factors can affect consumers in purchasing halal products. However, the consumption of halal-certified products is still relatively low.  This study was intended to analyze the factors that influenced consumer perceptions in purchasing halal products. A case study was carried out on the coffee product, one of Indonesia's most popular culinary products.  The data were collected based on a survey of 170 respondents who live in Surakarta, Central Java Province, and are Muslim. This study suggested that the factors that significantly influenced the purchase were the variables of religiosity, halal label certification, and product prices. In contrast, the variables of halal awareness and brand image had no significant effect. Thus, the five variables simultaneously had a significant positive effect on purchasing decisions for halal products.

Abstract

PT.Tirta Investama merupakan salah satu perusahaan Air Minum Dalam Kemasan (AMDK) yang menempatkan kualitas sebagai salah satu bagian dari strategi perusahaan. Ada beberapa permasalahan yang dihadapi perusahaan diantaranya masalah kualitas pada produk air minum dalam kemasan merek AQUA kemasan 240 ml yang tidak memenuhi spesifikasi pada proses filling. Penelitian ini bertujuan untuk mengidentifikasi cacat yang terjadi, menemukan penyebab terjadinya cacat, menganalisa pengaruh yang paling signifikan dari suatu kegagalan, dan memberikan usulan perbaikan. Dengan menggunakan pendekatan metode (DMAIC) Define, Measure, Analize, Improve, Control diharapkan perbaikan kualitas dapat dicapai. Berdasarkan pengukuran yang dilakukan diketahui bahwa proses yang mempunyai kontribusi terbesar terhadap kecacatan produk merek AQUA dengan kemasan 240 ml yaitu proses filling. Dengan menggunakan diagram pareto maka dapat diketahui critical to quality (CTQ) kunci yaitu cacat lid, cacat cup, cacat volume. Setelah itu dengan FMEA (Failure Mode Effect Analize) diketahui faktor yang paling berpengaruh menyebabkan cacat yaitu pemberhentian mesin saat produksi, untuk menanggulangi permasalahan tersebut perlu dilakukan upaya perbaikan yaitu dengan penambahan tambatan pada body mesin dan upaya pengendalian berupa pembuatan form analisis masalah untuk memantau jalannya produksi dan menganalisa setiap masalah yang ada dilantai produksi oleh semua operator yang terlibat. Kata kunci: Kualitas, Air Minum Dalam Kemasan, DMAIC, FMEA

Abstract

Water pump machines are electronic products that are widely used by the community. Because of the high frequency of use, this product is quickly damaged. In order to reduce the environmental impact, the ease of the product to be repaired or recycled needs to be improved, especially the dismantling process because it is the initial process to separate components. This study aims to evaluate the ease of dismantling a water pump machine based on the ease of component to be reached and the complexity of the component and product design. Evaluation begins by identifying the initial product design and the relationships between components needed to determine the order of possible product demolition and as an attribute of calculating complexity and accessibility indexes. The calculation results show that the complexity and accessibility idex values for each component are the same in all disassembly sequences because the product design does not allow for sub-assembly. The most complex components are mechanical seal, water reservoirs and lids beside the pump body. While the components that are most difficult to access are impellers, mechanical seals and rator covers.

Abstract

Permasalahan yang timbul di dunia ini seringkali mengandung ketidakpastian, logika fuzzy merupakan salah satu metode untuk melakukan analisis sistem yang mengandung ketidakpastian. Pada penelitian ini digunakan metode mamdani atau sering juga dikenal dengan metode Min – Max. Perancangan sistem untuk mendapatkan output dilakukan dalam tahap – tahap (a) pembentukan himpunan fuzzy, (b) Aplikasi fungsi implikasi, (c) membentuk aturan – aturan, (d) penegasan (defuzzifikasi). Pada penelitian ini defuzzifikasi dilakukan  dengan menggunakan metode centroid. Pada metode ini nilai defuzzyfikasi bergerak secara halus, sehingga perubahan pada himpunan  fuzzy juga akan bergerak dengan halus. Dari hasil penelitian yang telah dilakukan, dengan memasukkan variabel input  pada bulan juli 2005, yaitu jumlah permintaan sebesar 21.945 unit dan jumlah persediaan sebesar 1.824 unit menghasilkan output jumlah produksi sebesar 20.300 unit.

Abstract

Group Technology System merupakan metode pengaturan fasilitas produksi (machine groups) yang dibutuhkan untuk memproses suatu part family tertentu ke dalam sel-sel manufaktur. Pengaturan tata letak di CV. Sonytex yang berdasarkan process layout mengakibatkan perusahaan menghadapi permasalahan berupa tingginya kebutuhan material handling. Salah satu kriteria kinerja dalam pembentukan sel manufaktur pada GTS adalah meminimasi total jarak material handling, sehingga dapat mengurangi biaya material handling dan meningkatkan produktivitas. Dalam penelitian ini digunakan tiga metode, yaitu Bond Energy Algorithm (BEA), Rank Order Clustering (ROC) dan Rank Order Clustering 2 (ROC2). Hasil dari penelitian ini adalah dengan menerapkan group technology systems diperoleh total pengurangan jarak material handling sebesar 70 m dan penghematan biaya material handling sebesar Rp 1.534.978,-. Berdasarkan model simulasi, relayout dengan metode BEA meningkatkan jumlah produksi sebesar 1 unit produk/hari dan penurunan waktu tunggu sebesar 0,575 menit.

Abstract

Currently, waste is an important issue faced by almost all countries, including Indonesia, as it can have social and environmental impacts. Waste management needs coordination between local governments and waste-generating communities. The government must provide means of final waste disposal site. At present, Wonogiri District has five disposal sites located in 5 different sub-districts of Pracimantoro, Baturetno, Ngadirojo, Slogohimo and Purwantoro. Determination of alternative final disposal site in Wonogiri District is needed for more effective and optimum waste handling. Using Technique of Order Preference method by Similiary to Ideal Solution (TOPSIS), it is proposed in this article that the Baturetno site is the best alternative for final disposal site compared to the other four sites. This article also proposes a scheme for the further processing of waste into methane gas that can be utilized by the community.
