Abstrak: This research present an application of Resource Oriented Architecture with RESTful web service style at oil palm research station, PT. Sasaran Ehsan Mekarsari. The system consist of two major systems: Nursery Information System (IS) and Geographics Information System (GIS), with each part of the system built with two foundations: back-end and front-end. The experiment resulted that these RESTful design can be applied both at IS and GIS. The web service made Nursery Information System (IS) could cooperate easily with Geographics Information System (GIS) and vice versa to accommodate company needs. Standardized data format made the communication among each system run easier and open the scalability of the system at the future.

Judul: Rancang bangusn sistem informasi berbasis web untuk perencanaan pembudidayaan kelapa sawit
Abstrak: Palm oil is one of the leading plantation commodity in Indonesia. Area of palm oil plantations increased each year. This condition indicates the need of more man power supply with better understanding on palm oil cultivation. Web based information system was designed to improve the knowledge of people involving in palm cultivation. Web based information system has been developed with SDLC (System Development Life Cycle) which consists of five steps: System Investigation, System Analysis, System Design, System Implementation and System Maintenance. The system has been built with Joomla 1.5.2, which consist of four main menus : General Information, Cultivation Notes, Financial Analysis, and Community Forum. Results from the evaluation of information systems can be concluded that the information system meets users’ needs and ready for use. Keyword : palm oil, web-based information system, SDLC, Joomla

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.
