Judul: Pencarian Masjid Terdekat dengan Location Based Service (LBS) pada Android
Abstrak: When in a trip, a Muslim who wants to pray in the mosque timely, need the nearest mosque information. Such information can be provided through location based services (LBS). LBS consists of application components, component acquisition positions, mobile device, telecommunication networks, and service server. This research has successfully developed Android application that is able to provide the nearest mosque’s information and the mosque’s route on Google Maps. The application uses the acquisition component positioning using assisted global positioning system (A-GPS) in mobile devices. The mobile device used is a smart phone with Android operating system. Then, the telecommunications network uses global system for mobile communications (GSM) network or code division multiple access network (CDMA) network. Service server as content provider on the application is available through three Google API services: Google Maps API as the provider of maps, Google Place API as provider of mosque data, and Google Direction API as provider route to the mosque with the driving mode.

Judul: Pengembangan Aplikasi Pencarian Tempat Berbasis Mobile
Abstrak: Searching for a room in the building at a new area or even a frequently visited area may be a problem for some people. The purpose of this research is to develop a location based services (LBS) application which can search a place with the user’s current position as a reference. Place in this research is a room inside the building, such as classroom, laboratory, and auditorium. This research is conducted in several stages, the first is application development planning based on related references. The second is system requirement analysis, such as hardware specification and data. After that, the system is designed and implemented based on the previous two iterations of analysis, and finally, the system is tested for each function. The application is developed on Android platform using Google Maps API version two. User’s location coordinate is obtained by using assisted global positioning system ( A-GPS ) which can utilize the services from the service provider to determine the user's position at current time. This research’s result is an application that capable to show a route to the desired room along with its associated distance, travel time and room layout information.

Judul: Nisbah Kelamin Ikan Pelangi Iriatherina Werneri Pada Perbedaan Suhu Pemeliharaan
Abstrak: Ikan pelangi Iriatherina werneri merupakan ikan hias air tawar dari famili Melanotaenidae (Rainbowfishes) yang ditemukan di Papua. Ikan pelangi (Iriatherina werneri) jantan memiliki warna dan bentuk sirip yang indah, serta bernilai ekonomi lebih tinggi dibandingkan ikan betina. Penelitian ini dilakukan untuk mengevaluasi pengaruh perbedaan suhu pemeliharaan terhadap nisbah kelamin ikan pelangi Iriatherina werneri dalam wadah budidaya, kelangsungan hidup, derajat penetasan dan pertumbuhannya. Penelitian menggunakan Rancangan Acak Lengkap dengan perlakuan suhu (28-30 ºC, 30-32 ºC, dan suhu ruang) masing-masing dengan 5 ulangan. Perlakuan suhu diberikan mulai dari fase telur sampai 60 hari pemeliharaan. Hasil penelitian menunjukkan suhu mempengaruhi nisbah kelamin pada ikan pelangi (P<0,05). Persentase jantan pada perlakuan suhu 30-32 ºC lebih tinggi, yaitu 73,3% dibandingkan dengan perlakuan suhu 28-30 ºC sebesar 56,7%, sedangkan pada perlakuan suhu ruang menghasilkan 30% ikan jantan. Pada perlakuan suhu 28-30 ºC dan 30-32 ºC menghasilkan persentase ikan jantan dua kali lipat lebih tinggi yaitu sebesar 56,7% dan 73,3% dibandingkan dengan pemeliharaan pada suhu ruang sebesar 30%. Kelangsungan hidup pada penelitian ini berkisar antara 23,9% sampai 40,3%, derajat penetasan berkisar antara 43,4% sampai 47,2% dan pertumbuhan ikan pelangi pada perlakuan pemeliharaan dengan suhu 28-30 ºC menunjukkan kecenderungan pertumbuhan yang lebih tinggi dibanding perlakuan suhu 30-32 ºC dan suhu ruang, yaitu mencapai 23,4 mm.
