Abstract

Beras merupakan salah satu bahan makanan pokok sebagian besar masyarakat Indonesia yaitu sekitar 95% mengkonsumsi beras. Selain merupakan makanan pokok, kegiatan produksi dan aktivitas lainnya dalam rantai pasok beras melibatkan banyak pelaku di dalamnya. Dapat dipastikan setiap tahunnya permintaan beras akan bertambah, sementara pelaku dan transaksi yang harus dilalui cukup panjang membuat ketidakpastian stok beras tinggi. Penelitian ini bertujuan menyusun model rantai pasokan beras yang berbasis FIS (Fuzzy Inference System) Tsukamoto. Objek dalam penelitian ini adalah UD Rama. UD Rama sebagai unit penggiling beras atau pengepul beras. Ketidakpastian persediaan rantai pasokan beras di UD Rama menyebabkan tidak stabilnya pemesanan yang dilakukan oleh konsumen akhir sehingga menyebabkan kurang optimalnya pengelolaan manajemen rantai pasok. Penerapan Fuzzy Tsukamoto menjadi salah satu cara untuk mengurangi terjadinya ketidakpastian pasokan beras. Berdasarkan data permintaan, persediaan, dan pasokan yang diperoleh selama dua tahun dapat diambil empat aturan. Aturan tersebut menghasilkan enam himpunan fuzzy antara lain: permintaan NAIK, permintaan TURUN, persediaan BANYAK, persediaan SEDIKIT, pasokan BERTAMBAH, dan pasokan BERKURANG. Nilai perbedaan fuzzy dengan aktual sebesar 32 ton beras dengan nilai MAD 32,038.

Abstract

Research on consumer preferences on mountain shoe products is crucial. Mountain shoes are an important tool in mountain climbing activities that are at risk. Errors in the design of a mountain shoe cause inconvenience to consumers. This article discusses the factors that affect consumer satisfaction of mountain shoe products, so get the appropriate product design. Data processing is done by Kano method that shows response from respondent tend to spread. Another finding is that the number of values between categories in some attributes has an insignificant difference. Determination of Kano category is done by using Kano's satisfaction coefficient graph. The results show that the dominating category is must-be, ie 9 attributes need to be a priority because it is a basic need that must be met.

Abstract

Halal risk mitigation in certified poultry processing is the focus of this study.  The primary objectives are to map the important risk points in the halal poultry supply chain, understand how certification criteria are applied, and evaluate how stakeholder awareness and behaviour affect halal compliance. This research applied a descriptive qualitative approach, leveraging the case study technique through interviews with major stakeholders in the chicken meat supply chain. This research uses source triangulation techniques to validate the data by comparing information from interviews and literature reviews. The findings reveal several critical issues in the halal poultry supply chain, including limited control over halal inputs such as feed and vaccines, and low awareness among farmers regarding halal standards. Inadequate transaction documentation and the unclear halal status of chickens during transfer further compromise compliance. The slaughtering process often does not adhere to shariah requirements, with poor separation between clean and dirty areas, increasing the risk of cross-contamination. Additional concerns include contamination during transportation due to the use of non-designated or unhygienic vehicles, and the absence of halal labelling alongside the use of ingredients from unverified sources.
