Judul: Analisis Antrian Kapal di Pelabuhan Perikanan Pantai (PPP) Lampulo Banda Aceh
Abstrak: Queuing theory is the mathematical study of queues or waiting line events, which is a waiting line of constumers who require the service of the existing system. This study aims to identify the vessel queue landed in PPP Lampulo, identify the degree of usefulness of the system utility of unloading fasilities and identify the ship waiting time in the queue at PPP Lampulo. This study used a standard formula of a multi channel single phase to identify conditions of existing queue. The results showed that the model queue that occurred in PPP Lampulo was (M/M/5): (FCFS / I / I). Based on calculations by the standard formula queuing model, it was obtained that the rate of arrival of the vessel unloading was 14 vessels / day and the rate of the service time was 16 vessels / day. Value of waiting time in the queue was 0 hour and the number of vessels that queue did not exist, while the waiting time in the system was 2.5 hours and the number of ships arriving in the system was 1 ship.The result of the calculation also showed that utility value of the system almost reached the optimum value (0.875) and the probably no ship in a system was 0.42.

Judul: Analisis Penerapan Teori Antrian pada Sistem Penambatan Kapal Pelabuhan PT. Pelindo II cabang Tanjung Priok
Abstrak: Penelitian ini menjelaskan tentang pehitungan kinerja pelayanan pelabuhan untuk mendukung proses pengambilan keputusan guna meningkatkan kualitas pelayanan dan memenuhi permintaan di masa mendatang dengan menentukan sistem antrian pelayanan yang seharusnya diterapkan pada pelabuhan tanjung priok. Antrian pada sistem pelayanan penambatan kapal terjadi akibat ketidaksesuaian antara perencanaan dengan perealisasiannya. Teori antrian ini diterapkan didalam setiap fungsi fasilitas pelabuhan dan kegiatan operasional pelabuhan. Dalam metodologi ini, setiap waktu dari pergerakan kapal di dalam areal pelabuhan dianalisis. Waktu tunggu kapal di dalam dan luar areal pelabuhan dihitung menggunakan metode simulasi pada teori antrian sehingga menjadi sebuah model antrian. Simulasi dilakukan berdasarkan waktu kedatangan dan lama pelayanan yang sebenarnya. Hingga akhirnya menghasilkan sistem pelayanan penambatan kapal yang optimum. Berdasarkan hasil simulasi diperoleh nilai , ,dan yang jauh lebih singkat dari kondisi pada realisasi. Selain itu diperoleh juga bahwa utilitas sistem dari setiap dermaga dibawah angka 0,89 atau 89 persen. Hal tersebut juga didukung dengan nilai yang lebih besar dibandingkan realisasi. Penyebab potensial terjadinya kondisi tersebut terbagi menjadi 3 faktor, yaitu faktor internal, faktor eksternal,dan faktor cuaca. Sehingga dapat disimpulkan bahwa sistem pelayanan penambatan kapal yang diterapkan pada pelabuhan PT. Pelindo II cabang Tanjung Priok seharusnya mengikuti kondisi pada metode simulasi.

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.
