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: Redesign of the Layout of Production Facilities at the Bread Production House in Cipanas District
Abstrak: Rumah produksi roti di kecamatan cipanas merupakan salah satu usaha binaan IPB dan Astra International yang dikembangkan oleh tujuh desa meliputi Desa Batulawang, Desa Ciloto, Desa Cimacan, Desa Cipanas, Desa Palasari, Desa Sindanglaya, dan Desa Sindangjaya. Rumah produksi roti diresmikan pada bulan Maret tahun 2022 dan hingga saat ini masih dalam tahap persiapan dan pengembangan. Hal yang harus diperbaiki terkait tata letak fasilitas produksi adalah penempatan pintu toilet yang belum sesuai dengan aturan CPPB-IRT, penempatan peralatan yang belum memperhatikan pergerakan aliran bahan sehingga terdapat aliran bahan yang bolak-balik (backtracking), dan penempatan stasiun proofing dan stasiun baking yang berjauhan sehingga jarak tempuh pekerja menjadi lebih jauh. Penelitian ini bertujuan untuk merancang alternatif tata letak fasilitas produksi yang baru untuk memperbaiki kelemahan dari tata letak sebelumnya. Metode yang digunakan adalah pendekatan desain keteknikan yang meliputi tahap eksplorasi, verifikasi permasalahan, ideasi, pengembangan prototipe, dan validasi prototipe. Perancangan ulang tata letak fasilitas produksi dilakukan dengan menggunakan algoritma CORELAP. Hasil usulan tata letak fasilitas produksi terpilih memberikan total jarak perpindahan per batch produksi 90,92 m dengan biaya material handling Rp77.471,00., The bread production house in Cipanas sub-district is one of the fostered businesses of IPB and Astra International which was developed by seven villages including Batulawang Village, Ciloto Village, Cimacan Village, Cipanas Village, Palasari Village, Sindanglaya Village, and Sindangjaya Village. The bread production house was inaugurated in March 2022 and is still in the preparation and development stage. Things that must be improved regarding the production facility layout are the placement of the toilet door that is not in accordance with the CPPB- IRT rules, the placement of equipment that does not pay attention to the movement of the material flow so that there is backtracking, and the placement of proofing stations and baking stations that are far apart from each other resulting in longer distanc for workers. This study aims to create an alternative layout of a new production facility layout that can improve the weaknesses of the previous layout. The method used is an engineering design approach which includes the stages of exploration, problem verification, ideation, prototype development, and prtotype validation. The production facility layout redesign was carried out usuing the CORELAP algorithm. The result of the selected production facility layout provide a total displacement distance in one production batch of 90,92 m with material handling costs of Rp.77.471,00.

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.
