XYZ. This study aims to determine the factors causing the decline in productivity in the packing warehouse area. The first step of the research is to analyze the input data using a Pareto diagram. The source of problems that occur from outside the packing area are four cases, namely Canceled Delivery, Part Received Without Documents, No Stock and Quality Issue. Meanwhile, for problems that occur from internal packaging, there are two, namely the No Packaging Box and No Operator Entering. By using the Ishikawa diagram and 5 whys, the sources of problems that occur in the internal packing area are analyzed further and obtained several sources of problems that contribute greatly to the decline in productivity in the packaging area, namely the process of purchasing packaging boxes which takes quite a long time and long working hours from the packaging team. Some of the solutions for internal problems offered include changing the carton box procurement process using blanket orders, upgrading the team leader's capabilities with order and budget monitoring capabilities, proposing changes in the production flow for semi-finished goods and a proposal to create a temporary warehouse for semi-finished goods. \u0000Abstrak: Penelitian ini merupakan penerapan dari alat pengendalian qualitas dalam lingkup peningkatan produktivitas bagian pengepakan di PT. XYZ. Penelitian ini bertujuan untuk mengetahui faktor penyebab penurunan produktivitas diarea gudang pengepakan. Langkah awal penelitian dengan menganalisa data masukan menggunakan diagram Pareto. Sumber masalah yang terjadi dari luar area pengepakan ada empat kasus yaitu Pengiriman Dibatalkan, Part Diterima Tanpa Dokumen, Stock Tidak Ada dan Ada Issue Kualitas. Sementara untuk masalah yang terjadi dari internal pengepakan ada dua yaitu Box Pengemas Tidak ada dan Operator Tidak Masuk. Dengan menggunakan diagram Ishikawa dan 5 whys , sumber masalah yang terjadi di internal area pengepakan dianalisa lebih lanjut dan diperoleh beberapa sumber masalah yang berkontribusi besar terhadap penuruan produktivitas di area pengepakan yaitu proses pembelian box pengemas yang memakan waktu cukup lama dan jam kerja yang panjang dari tim pengepakan. Beberapa solusi untuk permasalah internal yang ditawarkan antara lain merubah proses pengadaan karton box dengan menggunakan blanket order, mengupgrade kemampuan team leader dengan kemampuan order dan budget monitoring, mengusulkan perubahan alur produksi untuk barang-barang setengah jadi serta usulan untuk membuat gudang sementara untuk barang setengah jadi. \u0000  \u0000 ","PeriodicalId":434078,"journal":{"name":"Sainteks: Jurnal Sains dan Teknik","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131184402","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}

Chitosan Edible film (CEF) berpotensi digunakan sebagai media untuk drug delivery system. Sebagai contoh obat antibiotik digunakan asam salisilat. Untuk mengendalikan karakteristik edible film dan laju pelepasan obat (drug release), proses taut silang (crosslinking) perlu ditambahkan dalam pembuatan edible film dari kitosan dengan NaTPP sebagai crosslinker. Penelitian ini bertujuan untuk mempelajari pengaruh crosslinker NaTPP terhadap sifat fisik CEF. Tahapan percobaan pada penelitian ini adalah: (1) pembuatan CEF dengan variasi NaTPP (0; 0,05; 0,1; 0,2%  m NaTPP/V larutan, (2) menganalis sifat fisik CEF yang diukur adalah kuat tarik, persen pemanjangan, dan swelling. Hasil penelitian menunjukkan bahwa penambahan NaTPP mempengaruhi sifat fisik CEF.

CDRC (Characteristic Drying Rate Curve) and REA (Reaction Engineering Approach) adalah salah satu model mekanistik untuk mencari kondisi fisis di semua bagian, yang tidak bisa dilakukan oleh model empirikal. Hasil yang diperoleh dengan cara simulasi menunjukkan profil temperatur dan kadar air pada jaringan mangga yang telah divalidasi berdasarkan literatur. Mean square error dan nilai variasinya menunjukkan kemiripan antara kadar air dan temperatur. Data eksperimen untuk REA menggunakan temperatur pengeringan 338K dan nilai Y pada 0,0134kg H2O/kg udara kering. CDRC dibagi menjadi dua pendekatan model, Constant Rate Period (CRP) dan Falling Rate Period (FRP) pada temperatur 338K. Penentuan energi aktivasi relatif diperoleh sebagai jumlah kadar air yang hilang, pada temperatur 328K. Hasil yang ditunjukkan model CDRC dan REA relatif sama, dimana CDRC lebih mendekati data eksperimen.

Therefore the Purwakarta Regency government made a program called Operation Jatiluhur Jernih Lake through the Decree of the Regent of Purwakarta No.523.31.05 / Kep.286-DLH / 2017.  This program had a purpose to curb a number of cageculture in Jatiluhur Dam.
