Judul: Perencanaan distribusi dan transportasi dengan teknik klasifikasi untuk mendukung konsep manajemen rantai pasok
Abstrak: Proses distribusi dan trasnportasi merupakan salah satu bagian penting dalam manajemen rantai pasok. Distribusi merupakan manajemen untuk menyalurkan produk ke tangan konsumen pada waktu yang tepat dan kualitas yang terjamin. Pada penelitian ini perencanaan distribusi dilakukan dengan membuat Bill of Distribution (BOD) yang menggambarkan struktur distribusi industri, kemudian menyusun Distribution Requirements Planning (DRP) untuk mengetahui berapa jumlah produk yang seharusnya tersedia di finished goods warehouse pada waktu tertentu. Proses ini akan berkaitan langsung dengan perencanaan transportasi. Sebuah proses pengangkutan produk dari satu tempat ke tempat lain dengan mempertimbangkan karakteristik produk, jumlah produk, kendaraan yang dipakai, dan rute perjalanan yang dilalui. Teknik Minimum Spanning Tree (MST) akan digunakan dalam penentuan rute perjalanan, sehingga satu kali keberangkatan dapat mengantarkan produk ke beberapa tujuan sekaligus.

Judul: Perencanaan Distribusi dan Transportasi dengan Teknik Klasifikasi untuk Mendukung Konsep Manajemen Rantai Pasok
Abstrak: The number of industries in the world is constantly increasing, this fact makes the industry should work harder to add and retain customer. Industry must make the customer satisfied by offering best quality products at the right time. Good supply chain management is the best solution to solve it. Product will be controlled either from raw materials until arrive at the customer. An important part of the supply chain is distribution and transport planning. Delivery of products must be planned, so First In First Out (FIFO) system can be implemented and products arrive at the right time. This paper will conduct a distribution and transport planning with Bill of Distribution (BOD) which can be used to make Distribution Requirements Planning (DRP) and analyze delivery orders data from an agroindustrial company with tires products using classification techniques. Classification technique is one of data mining technique, classification can be described as a supervised learning algorithm in the machine learning process. This research use classification technique to decide which transporter must be chosen to make on time delivery. It assigns class labels to data objects based on prior knowledge of class which the data records belong .The results of this analysis data are 70 rules that show what path should be chosen so the product arrived at destination on time. The rules will be used to make transport planning and an optimal route for product delivery with the lowest cost will be planned using Minimum Spanning Tree (MST). All these technique is expected to reduce distribution and transportation cost, but still makes the product arrive on time.

Judul: Durability of Specific Immunoglobulin (Ig) Y Againts Influenza and Covid-19 in Sunscreen
Abstrak: The benefit of specific immunoglobulin Y (Ig Y) as an active ingredient in personal care products such as sunscreen has not been properly studied. Our study aims to evaluate the reliability of specific IgY against influenza and the COVID-19 virus in a sample sunscreen product. Specific IgY influenza and COVID-19 viruses were inserted in the sample sunscreen at two concentrations of 0.1% and 0.25%. Three treatments were observed: control (C) sunscreen without IgY, treatment 1 (T1) sunscreen with 0.1% IgY, and treatment 2 (T2) sunscreen with 0.25% IgY. Organoleptic observations were carried out to monitor changes in aroma, color, and texture, and sunscreen sampling was done every week for 6 weeks. The durability of IgY was evaluated using an enzyme-linked immunosorbent assay (ELISA) and a neutralization assay. Organoleptic observation from weeks 1 to 6 showed consistency in its aroma, color, and texture. Enzyme-linked immunosorbent assay and neutralization assay (NA) results of the T1 and T2 groups showed negative results except for sample T1 at week 5, which showed a positive result in the Influenza A ELISA. Based on the results, it seems that IgY concentrations of 0.1% or 0.25% were not optimal. However, this negative result might be due to low concentration of the IgY and the presence of beeswax, which inhibits IgY and causes it to dissolve in distilled water, thus preventing it from being detected in the assay.
