The purpose of this study was to produce tablets of temulawak (Curcuma xanthorrhiza Roxb.) with variations in the addition of maltodextrin concentration and to find the best results. This research was conducted using a non-factorial Randomised Block Design (RBD) with 3 treatment levels, the ratio of maltodextrin to 1:2 (50%), 1:4 (25%) and 1:6 (16.70%).  The results of this study showed that all tablets formed met the requirements of BPOM Number 32 of 2019 such that the tablets must be less than or equal to 10% and all the shaped tablets had a uniform weight. The tablets with 1:2 (50%) treatment had the highest value which was able to produce the highest total mean value of phenolics and flavonoids when compared with 1:4 (25%), 1:6 (16,70%) and control treatments. In a 1:2 (50%) treatment, the total phenolic value was 3.63 mg GAE/g ± 0.09, while the total flavonoid value was 6.11 mg QE/g ± 0.30. Therefore, it can be stated that the maltodextrin concentration treatment with a ratio of 1:2 (50%) was the optimum method for producing temulawak (Curcuma xanthorrhiza Roxb.) tablets in this study.","PeriodicalId":229622,"journal":{"name":"Jurnal Teknotan","volume":"105 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139163722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salah satu sampah anorganik yang banyak dihasilkan dari suatu proses industri atau rumah tangga adalah sampah plastik. Laboratorium Alat dan Mesin Pertanian Fakultas Teknologi Industri Pertanian Universitas Padjadjaran sudah mengembangkan mesin pencacah plastik tipe reel namun mesin tersebut belum dilakukan analisis ekonomi dan ergonomi. Tujuan penelitian ini adalah melakukan analisis kelayakan ergonomi dan ekonomi untuk mesin tersebut. Metode yang digunakan dalam penelitian ini adalah survei deskriptif yaitu melalui pengukuran antropometri, perhitungan beban kerja, biomekanik, ekonomi dan tingkat kebisingan, pengisian kuesioner dan wawancara. Adapun tahapan penelitian adalah sebagai berikut; observasi lapang, pengumpulan data, pengolahan dan analisis data, analisis beban kerja, analisis biomekanika, analisis ekonomi dan analisis kebisingan. Berdasarkan hasil penelitian menunjukkan bahwa dimensi mesin pencacah plastik berdasarkan hasil pengukuran antropometri belum memenuhi kaidah ergonomi karena tinggi hopper 170 cm  melebihi tinggi bahu operator 140 cm dan tinggi outlet 40 cm lebih rendah dari tinggi pinggul operator 96 cm sehingga pada saat pengoperasian mesin operator merasa tidak nyaman. Hasil skor REBA yang didapat yaitu 7 untuk posisi menyalakan mesin dan pengambilan hasil cacahan sementara didapatkan skor 6 untuk posisi memasukkan bahan ke dalam hopper, hasil tersebut menunjukkan belum sesuai dengan kaidah ergonomi karena tergolong tingkat resiko sedang. Hasil uji kebisingan yaitu pada hopper 97,9 dB dan outlet 102,24 dB  kondisi dengan beban, hasil tersebut belum sesuai dengan kaidah ergonomi karena melebihi standar yaitu 85 dB. Hasil analisis kelayakan usaha menunjukkan bahwa mesin sudah layak secara ekonomi, karena hasil menunjukkan NPV Rp. 37.354.120 > 0, BCR 1,11 > 1, IRR 2,07% > suku bunga MARR (suku bunga deposito Bank BRI  2%), dan PBP pada bulan ke- 24.","PeriodicalId":229622,"journal":{"name":"Jurnal Teknotan","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132150718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
