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: Scale up Production Design for Rice Milling at CV Mekar Jaya (SIJAMAL Corp.)
Abstrak: CV Mekar Jaya merupakan perusahaan penggilingan padi yang berkeinginan untuk mencapai target pasar Food Station Tjipinang Jaya yang memiliki kapasitas produksi minimum 200 ton beras/minggu. Penelitian ini bertujuan untuk merancang proses scale up produksi penggilingan padi di CV Mekar Jaya yang efektif dan efisien. Penelitian ini menggunakan metode deskriptif dengan pendekatan kuantitatif melalui observasi, wawancara, dan studi literatur. Hasil eksplorasi menunjukkan bahwa permasalahan yang terjadi meliputi kondisi dan kapasitas mesin pengering yang belum memadai serta kurangnya peralatan dan mesin produksi yang digunakan. Konsep solusi dilakukan melalui penentuan kapasitas bahan baku, perhitungan neraca massa, kebutuhan energi dan jumlah bahan bakar pada proses pengeringan, pemilihan peralatan produksi serta analisis kelayakan finansial. Hasil iterasi menunjukkan dengan input bahan baku 65.000 kg GKP/hari dapat menghasilkan sekitar 31.625,88 kg beras/hari dengan kebutuhan energi sebesar 29.660.034,8 kJ dan jumlah bahan bakar sebanyak 1558,02 kg biopelet kayu. Perhitungan menunjukkan HPP beras yang dihasilkan sebesar Rp 12.691/kg. Analisis kelayakan finansial menunjukkan bahwa rancangan peningkatan skala produksi ini dinilai layak untuk dikembangkan karena memiliki nilai NPV Rp 5.148.686.573, nilai IRR 23,92%, nilai B/C 1,11, nilai BEP 103.256 unit, dan payback period selama 3 tahun 4 bulan. Berdasarkan analisis sensitivitas, keuntungan usaha dapat ditingkatkan dengan melakukan penurunan biaya produksi., CV Mekar Jaya is a rice milling company that wants to reach the Tjipinang Jaya Food Station market target which has a minimum production capacity of 200 tons of rice/week. This research aims to design an effective and efficient scale-up process for rice milling production at CV Mekar Jaya. This research uses a descriptive method with a quantitative approach through observation, interviews and literature study. The exploration results showed that the problems that occurred included the inadequate condition and capacity of the drying machine as well as a lack of equipment and production machines used. The solution concept is carried out through determining raw material capacity, calculating mass balance, energy requirements and the amount of fuel in the drying process, selecting production equipment and analyzing financial feasibility. The iteration results show that with a raw material input of 65,000 kg GKP/day it can produce around 31,625.88 kg ii rice/day with an energy requirement of 29,660,034.8 kJ and a quantity of wood biopellet fuel of 1558.02 kg. The calculation is that the HPP for the rice produced is IDR 12,691/kg. The financial feasibility analysis shows that the design for increasing the production scale is considered feasible for development because it has an NPV value of IDR 5,148,686,573, an IRR value of 23.92%, a B/C value of 1.11, a BEP value of 103,256 units, and a payback period of 3 years 4 months. Based on sensitivity analysis, business profits can be increased by reducing production costs.

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.
