Judul: Pengembangan Sistem Rotasi Peta pada Perangkat Mobile tanpa Sensor Magnetometer
Abstrak: Due to the improvement of technology, the function of mobile phone has changed a lot. Nowadays, mobile phone is used not only for communication, but also to support the user’s activity. Many mobile phones now have Operating System (OS) and sensors like GPS and magnetometer. GPS is a sensor that can be used to identify any location, including the location of the user, while magnetometer can be used to identify direction. With data that come from GPS and magnetometer, we can build a navigation application that can rotate its map according to the rotation of the user. Meanwhile, in the Android Compability Definition Document point 1.6 until 2.2, Google have requirements for mobile phones to have GPS and magnetometer sensors if they want to use Android OS. But, since the release of 2.3.3 OS, Google has changed its requirements, allowing any mobile phones to have Android OS without having the magnetometer sensor. The objective of this research is to build an navigation application that can rotate without using magnetometer sensor. The value of the rotation degree is taken from last two position. To stabilize the value, Exponential Smoothing is used in filtering process. This system also use Haversine method to recognize whether the user is walking or driving/riding.

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: Pemberian Pakan berupa Daging Ikan Gabus Channa striata yang Mengandung Albumin untuk Meningkatkan Performa dan Penyembuhan Luka pada Benih Ikan Louhan Cichlasoma spp.
Abstrak: Ikan louhan (Cichlasoma spp.) merupakan ikan hias yang sangat digemari di Indonesia dan memiliki nilai ekonomis tinggi, benih ikan ukuran 7-8 cm dengan kualitas bagus berharga 1-2 juta rupiah. Ukuran besar kepala, morfologi badan, dan lebar ekor menjadi parameter utama kualitas ikan louhan (Cichlasoma spp.). Pembudidaya melakukan penyayatan pada sirip dan mempertarungkan ikan untuk memperoleh sirip yang lebih lebar dan meningkatkan ketahanan terhadap stres. Luka yang disebabkan penyanyatan ekor dan pertarungan ikan sangat berpotensi menimbulkan infeksi. Solusi yang ditawarkan adalah memberikan pakan yang memiliki kandungan albumin. Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian albumin yang berasal dari ikan gabus (Channa striata) terhadap peningkatan kualitas serta penyembuhan luka akibat kerusakan fisik pada benih ikan louhan. Penelitian ini terdiri dari tiga perlakuan dan lima kali ulangan yaitu PK (100% pakan komersil), PK+PG (50% pakan komersil + 50% daging ikan gabus), PG (100% pakan yang berasal dari ikan gabus). Ikan louhan yang digunakan memiliki bobot rata-rata 12,08±0,98 g dengan panjang rata-rata 6,38±0,23 cm. Hasil penelitian menunjukkan luka sayatan pada ekor ikan sembuh paling cepat pada perlakuan PG yaitu 5 hari. Perlakuan PG juga mampu meningkatkan kualitas ikan louhan pada parameter lebar badan (18,25 ± 0,37 mm) dan bobot akhir (29,55 ± 1,75 g).
