Judul: Pemetaan berbasis web dengan menggunakan mapserver dan phpmapscript : studi kasus kampus Institut Pertanian Bogor Darmaga
Abstrak: Peta merupakan deskripsi dari suatu lokasi yang dituangkan dalam suatu bentuk gambar. Sebuah peta dapat lebih bermanfaat dalam menyampaikan informasi yang berkaitan dengan posisi suatu tempat dibandingkan dengan hanya menyediakan data tabular saja. Peta yang disajikan dalam suatu sistem yang berbasis web akan lebih mudah diakses oleh user dibandingkan peta yang hanya disajikan pada sistem yang bersifat stand alone. Peta yang berbasis web dapat diakses dengan waktu dan tempat yang tidak ditentukan. Untuk menghasilkan peta berbasis web dapat menggunakan suatu aplikasi MapServer. MapServer menyediakan beberapa fitur yang diperlukan untuk pengolahan suatu peta misalnya memperbesar atau memperkecil ukuran skala peta, mencari suatu lokasi, dan mengambil informasi yang berkaitan dengan lokasi tersebut. Fitur-fitur tersebut dapat langsung digunakan dengan bantuan PHPMapscript sebagai suatu script pemrograman yang dikhususkan untuk mengakses struktur internal MapServer. Sistem pemetaan berbasis web yang menggunakan MapServer dapat dijalankan pada server dengan sistem operasi Windows atau Linux. Data geografi yang dapat digunakan dalam implementasi bisa berupa data dalam format vektor atau format raster. Format vektor diantaranya shapefile, ESRI SDE, POSTGIS atau Oracle Spatial, dan untuk format raster diantaranya file PNG, TIFF, JPEG dan GIF. Sistem pemetaan berbasis web yang menggunakan MapServer pada saat dijalankan akan menghasilkan suatu file gambar. Ukuran file gambar ini dipengaruhi oleh ukuran peta dan skala peta. Semakin besar ukuran peta yang ditampilkan pada browser maka semakin besar pula ukuran file gambar yang akan dihasilkan dari proses yang dikerjakan MapServer. Jika skala peta semakin kecil maka ukuran file gambar akan semakin kecil karena jumlah item gambar yang ditampilkan akan semakin sedikit. Begitu juga sebaliknya jika skala semakin besar maka jumlah item gambar yang ditampilkan akan semakin banyak sehingga ukuran file gambar akan semakin besar. Dengan menggunakan MapServer, sistem pemetaan berbasis web dapat dijalankan dengan kecepatan akses yang cukup baik.

Judul: Geographic Information System of Bogor Facilities Using Pmapper Framework.
Abstrak: There are several sites that provide information about location of points of interest in the City of Bogor based on data up to February 2009, such as www.kotabogor.go.id, www.indotravelers.com, www.pu.go.id, www.asiamaya.com, and www.bogor.net. However, these sites only provide the information in the form of tables or static map (image in JPEG or TIFF format) which is not displayed in a full and complete form. Another problem is that the information provided through this map is not informative enough and can not show the locations in the form of dots on geographic areas of Bogor City. Therefore, the Geographic Information Systems of Bogor City Facilities is developed as the solution to these problems. This Geographic Information Systems of Bogor City Facilities is developed by using the GIS Development Guide published by the Department of Geography at Buffalo, on Microsoft Windows platform using Pmapper framework 3.2.0, PostgreSQL 8.2, PostGIS 1.2.1, and MS4W 2.3.1. The functions of this system are to zooming in/out the map, searching for locations, printing a map in the form of PDF or HTML, adding a new object and retrieving information related to the location. The Geographic Information Systems of Bogor City Facilities is developed as a system that provides information about the locations in the city of Bogor in full, webbased, dynamic and interactive form. The included locations are villages, districts, landuse, roads, rivers, government facilities, public services, major businesses as well as tourism sites.

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.
