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: Analysis Comparison Fisheries of Purse Seine in Lampulo Fishing Port Banda Aceh
Abstrak: This research was realized in January - February 2013 at Lampulo Fishing Port Banda Aceh. The method was used in this study such as descriptive method and investing criteria analysis. The Respondent were determined by purposive sampling for arrest facilities ownership. The Patrons who have infrastructure (20 persons) to get repayment and clien (20 persons) also get it as a fee from their job. The purpose this study were: (1) Comparison financial feasibility of purse seine fisheries in Lampulo. (2) Analyzing profit-sharing system for every purse seine patterns in Lampulo The calculations results of the purse seine fisheries feasibility between the daily and weekly seems from the businesses criteria value respectively, there were adventages and repayment period was quickly too with ROI value is th greater than capital cost. Then, the investing feasibility calculation result in purse seine fisheries both of daily and the weekly were viewed of each investing criteria value, where NPV > 0, Net B/C > 1 and IRR> 10% than interest rate. It caused purse seine fishing businesses in Lampulo still qualified and feasible to continued. The profit-sharing traditional system in Lampulo showed unbalanced between patrons and clients income. The patrons income is greater. Moreover, profit-sharing among clients (fishing master, collector, mechanical dan ABK). Proceeds from sales of the fish (gross income) reduced by 35% (10% for treatment, 10% for Toke bangku, 10% for fishing master and 5% for the interpreter engine). Later, it was reduced with operational costs. The arrest result was shared between owners and clien based on the net income divided into 3 section, one part for the crew and the two parts to the owner.

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.
