Judul: Rice Production Layout Design and Determination of Grain Supply Partnership Patterns at CV Mekar Jaya.
Abstrak: Peran beras sebagai makanan pokok bagi sebagian besar penduduk, memiliki pengaruh penting dalam kestabilan ekonomi dan sosial. CV Mekar Jaya merupakan perusahaan yang bergerak dalam proses produksi beras. Target pasar yang ingin dicapai oleh CV Mekar Jaya adalah Jakarta Food Station yang memiliki kapasitas produksi minimal sebanyak 200 ton beras per minggu. Hasil eksplorasi mengindikasikan adanya permasalahan dalam mencapai target tersebut diantaranya tata letak proses produksi yang belum efisien karena adanya aliran bolak-balik serta belum adanya pola kemitraan dalam sistem pengadaan gabah. Konsep solusi kemudian dirancang untuk menjawab permasalahan tersebut yaitu dengan perancangan tata letak dengan algoritma blocplan, penentuan pola kemitraan, serta penentuan target jangkauan kemitraan. Hasil iterasi solusi keteknikan menunjukan tata letak usulan memiliki nilai Adj-Score 0.97, R-Score 0.88 dengan Rel-Dist Score -212, tidak terindikasi adanya aliran balik serta mampu mereduksi jarak sebesar 22.8% dan OMH 16.69% dari tata letak saat ini. Penambahan conveyor menghasilkan OMH sebesar Rp. 1.281.900,32. Kemitraan yang ditentukan yaitu kemitraan berbasis komunitas dengan prinsip transparansi, kejujuran, keadilan dan kesejahteraan bersama. Total jumlah pasokan gabah pada kondisi existing berdasarkan hasil simulasi yaitu rata-rata 247.43 ton gabah/bulan atau belum memenuhi target, sehingga dilakukan perluasan target kemitraan. Target daerah perluasan kemitraan yang terpilih pada Kabupaten Karawang yaitu Kecamatan Tempuran, Kutawaluya, dan Cilamaya Wetan sedangkan pada Kabupaten Subang yaitu Kecamatan Ciasem, Patokbeusi, dan Compreng dengan total ketersediaan mencapai 1800 ton gabah/bulan., The role of rice as a staple food for the majority of the population has an important influence on economic and social stability. CV Mekar Jaya is a company that operates in the rice production process. The target market that CV Mekar Jaya wants to achieve is the Jakarta Food Station which has a minimum production capacity of 200 tons of rice per week. The exploration results indicate that there are problems in achieving this target, including the layout of the production process being inefficient due to backtracking and the absence of a partnership pattern in the grain procurement system. The solution concept was then designed to answer these problems, namely by designing the layout using the blocplan algorithm, determining the partnership pattern, and determining the target reach of the partnership. The results of the engineering solution iteration show that the proposed layout has an Adj-Score of 0.97, an R-Score of 0.88 with a Rel-Dist Score of -212, there is no indication of backtracking flow and is able to reduce distance by 22.8% and OMH 16.69% from the existing layout. The addition of a conveyor produces an OMH of Rp. 1,281,900.32. The partnership determined is a community-based partnership with the principles of transparency, honesty, justice and mutual prosperity. The amount of grain supply in existing conditions based on simulation results is an average of 247.43 tons of grain/month or has not met the target, so the partnership target has been expanded. The selected target area for partnership expansion is Karawang Regency, namely Tempuran, Kutawaluya, and Cilamaya Wetan Districts, while Subang Regency is Ciasem, Patokbeusi, and Compreng Districts with a total availability of up to 1800 tons of grain/month.

Judul: Design for Performance Improvement and Value Addition in Rice Supply Chain at Modern Rice Milling Plant Perum BULOG Subang
Abstrak: Modern Rice Milling Plant (MRMP) Subang merupakan perusahaan penggilingan padi yang mulai beroperasi pada bulan Oktober tahun 2022 sehingga belum pernah melakukan identifikasi terhadap kondisi rantai pasoknya. Proyek desain utama ini bertujuan mengidentifikasi situasional, kinerja, dan nilai tambah rantai pasok beras, merumuskan strategi peningkatan kinerja dan nilai tambah rantai pasok beras dan merancang ulang model rantai pasok baru. Analisis situasional rantai pasok menggunakan pendekatan Food Supply Chain Management (FSCM). Analisis kinerja rantai pasok menggunakan metode Supply Chain Operations Reference Digital Standard (SCOR DS). Nilai kinerja rantai pasok pada MRMP Subang dan mitra penyalur berturut-turut adalah 76,85% dan 68,54%. Nilai tambah dianalisis menggunakan metode hayami dan didapatkan nilai tambah sebesar Rp843.000/ton Gabah Kering Panen (GKP) atau sebesar 12,41%. Kinerja dan nilai tambah rantai pasok beras dapat ditingkatkan menggunakan model Analytical Network Process (ANP).Strategi peningkatan kinerja dan nilai tambah terpilih adalah penerapan sistem perencanaan produksi dan penerapan sistem jaminan mutu yang dimasukkan pada rancangan model rantai pasok yang baru., Modern Rice Milling Plant (MRMP) Subang is a rice milling company that started operations in October 2022 and has never identified its supply chain conditions. This major design project aims to identify the rice supply chain's situational, performance, and added value, formulate strategies to improve the performance and added value of the rice supply chain, and redesign a new supply chain model. The situational analysis of the supply chain used the Food Supply Chain Management (FSCM) approach. Supply chain performance analysis using the Supply Chain Operations Reference Digital Standard (SCOR DS) method. The supply chain performance scores for Subang MRMP and supply partners were 76.85% and 68.54%, respectively. The added value was analyzed using the Hayami method and obtained an added value of IDR 843,000/ton of Harvested Dry Grain (GKP) or 12.41%. The performance and value-added of the rice supply chain can be improved using the Analytical Network Process (ANP) model. The selected performance improvement and value-added strategies are the implementation of a production planning system and a quality assurance system incorporated in the design of the new supply chain model.

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.
