Judul: Redesign Tata Letak Fasilitas Produksi Dalam Meningkatkan Efisiensi Operasi
Abstrak: PT. XYZ has a land area of about 74 220 with 22 190 m2 of buildings and facilities of about 22 531 . The layout of the PT. XYZ classified into layout based process. By using the Map From-To on the flow of finished goods and materials obtained by the amount of movement of goods between work stations each day. PT. XYZ has designed a layout with a good, visible from the flow pattern in the form of a 'U'. In addition, space is a top priority production company located in the midpoint of the overall building company and in accordance with the results of the count Total Closenes Ratting (TCR), which is the largest production halls with a value of 302. The research using analytical approach Systematic Layout Planning (SLP), Activity Relation Chart (ARC) Analysis which is used to determine the level of relationship between production activities and produces a temporary layout. After determining the center point of a new work station, the distance between the station acquired a new work. The total flow of materials long distances is 8.112 meters / shift or equal to 24.336 meters / day, while the total distance of the new material flow is as far as 4.419 meters / shift or 13.257 feet / day. This means that the material flow can be reduced as far as 3.693 meters / shift or 11.079 meters / day.

Judul: Analisis Perancangan Ulang Tata Letak Fasilitas Produksi Pabrik Lama Pada CV Massitoh Catering Services
Abstrak: Tuntutan jaminan mutu pangan yang menjadi perhatian khusus bagi perusahaan. CV Massitoh Catering Services merupakan salah satu perusahaan jasa boga di Kabupaten Bogor. Untuk itu perusahaan ini berambisi untuk mendapatkan sertifikasi ISO 22000. Salah satu upaya untuk memenuhi standar yang ditetapkan perlu adanya perancangan ulang tata letak dan fasilitas. Penelitian ini bertujuan untuk (1) mengidentifikasi aspek-aspek yang terkait dengan tata letak stasiun kerja dan fasilitas yang ada di CV Massitoh Catering Services, (2) menganalisis tata letak berdasarkan hasil kajian, (3) merancang ulang tata letak berdasarkan hasil kajian sebagai suatu rekomendasi. Penelitian menggunakan analisis Activity Relation Chart (ARC) untuk mengetahui tingkat hubungan antar aktivitas produksi. Sementara untuk menyusun rancangan tata letak fasilitas produksi digunakan analisis Peta Dari-Ke (From-To Chart). Analisis Peta Dari-Ke menggunakan data masukan berupa aliran bahan, luas lantai, dan hubungan antara aktivitas produksi. Kemudian dilakukan perhitungan jarak antar stasiun kerja dengan perhitungan rectilinear. Setelah mendapatkan data dan informasi kemudian dilakukan perbandingan jika dilakukan perancangan ulang dengan menggunakan perangkat lunak Unequal-Area Facility Layout Problem (UA-FLP). CV. Massitoh Catering Services memiliki luas sekitar 569 m2 dibagi menjadi dua bangunan yang terpisah dengan jarak sekitar 60 m. Bangunan pertama memiliki luas sekitar 425 m2 terdiri dari kantor dan beberapa ruang penyimpanan bahan baku dan peralatan. Sementara untuk bangunan kedua memiliki luas sekitar 144 m2 merupakan tempat untuk memasak. Faktor-faktor yang mempengaruhi tata letak pada CV. Massitoh Catering Services antara lain: (1) hubungan antar stasiun kerja, (2) aliran produksi dan (3) jarak antar stasiun kerja. Tata letak pada CV. Massitoh Catering Services digolongkan kedalam tata letak berdasarkan proses. Dengan menggunakan metode Peta Dari-Ke diperoleh jumlah perpindahan bahan dan barang antar stasiun kerja setiap harinya. Kemudian dengan menghitung jarak antar stasiun kerja dengan perhitungan rectilinier diperoleh jarak tempuh proses produksi dalam sehari sejauh 502,723 meter. Analisis Activity Relation Chart (ARC) digunakan untuk mengetahui tingkat hubungan antar aktivitas produksi dan menghasilkan layout sementara. Analisis UA-FLP menghasilkan tata letak baru dan setelah menetukan titik pusat stasiun kerja yang baru, diperoleh jarak antar stasiun kerja yang baru. Total jarak material flow yang baru adalah sejauh 77,028 meter. Ini berarti material flow dapat berkurang sejauh 425,695 meter.

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.
