Abstract

 PT XYZ is one of the company which refers to furniture industries sector. The problem which faced by this company is unbalance of the production line which is caused by the unequal of work responsibility distribution in each work station. This problem caused the performance of line balance doesn’t work properly. To solve this problem we need to do the line balancing of production line. It can be done by line balancing methode that assigns a number of work which is related in one production line until each work station has efficient time which is not more than the cycle time of the work station. Line balancing methode that used is heuristic methode which is devided into ranked positional weight methode, large candidate rule methode, and region approach methode. From those three heuristic methode that used as solution of line balancing, there was improvement happenned with the same value in doors of production line. Line efficiency increased into 94,07% from 62,71% at the beginning condition. Balance delay increased into 5,92% from 37,28% at the beginning condition. The idle time descreased into 12,39 minutes from 116,87 minutes at the beginning condition. The smoothness index descreased into 7,44 from 64,67 at the beginning condition.

Abstract

Green coffee powder (GCP) adalah produk kopi yang tidak melalui proses sangrai dan tanpa penambahan bahan lain. GCP tergolong produk pangan segar asal tumbuhan (PSAT). Produk ini sudah dikomersilkan melalui e-commerce baik dalam bentuk powder maupun kapsul, namun belum didukung dengan standar yang menjadi syarat mutu. Kajian ini bertujuan untuk menentukan kritera mutu GCP sekaligus untuk mendukung pengembangan Standar Nasional Indonesia (SNI). Kajian dilakukan melalui beberapa tahapan meliputi observasi ke IKM penggiat kopi antara lain IKM Kopi Puncak Malino dan IKM Kopi Turaya. Selain itu, telah dilaksanakan Focus Group Discussion (FGD) dengan melibatkan berbagai stakeholder yang bertindak sebagai narasumber dan peserta baik dari kalangan pemerintah, akademisi, asosiasi dan industri. Hasil dari kegiatan observasi dan FGD menjadi bahan masukan penulis dalam menentukan kriteria mutu GCP berdasarkan aspek kualitas, keaslian produk, aktivitas dan keamanan pangan. Kriteria mutu tersebut antara lain keadaan produk, kadar air, kadar dan kealkalian abu, ukuran partikel, kadar kafein, sari kopi, asam klorogenat, cemaran mikroba, dan cemaran logam. Kajian ini belum menetapkan syarat nilai dari tiap kriteria mutu yang direkomendasikan. Seluruh kriteria mutu mengacu pada SNI 8964:2021 Kopi Sangrai dan Kopi Bubuk
