Judul: Analisys gerakan robot berkaki enam menggunakan 3 Servo dan Sensor Jarak
Abstrak: Pada umumnya, hexapod menggunakan 18 servo. Namun, penggunaan servo yang terlalu banyak mengakibatkan konsumsi daya yang terlalu besar, biaya yang mahal, algoritme pergerakan kaki yang kompleks, dan pergerakan kaki yang lambat. Penelitian ini bertujuan mengembangkan hexapod dengan 3 servo, yang diletakkan di bagian tengah dan belakang robot. Peletakan servo di bagian tengah digunakan untuk mengangkat kaki depan dan belakang pada sisi yang sama, sedangkan peletakan dua buah servo pada bagian belakang robot digunakan untuk menggerakkan kaki depan dan belakang yang sudah saling terhubung. Algoritme pergerakan kaki yang digunakan adalah algoritme Alternating Tripod Gait yang membagi gerakan kaki menjadi 2 set gerakan seperti tripod. Tiap set gerakan terdiri atas 3 kaki, yaitu kaki depan dan belakang pada sisi yang sama, serta kaki tengah pada sisi yang berbeda. Masing-masing set bergerak secara bergantian. Hasil penelitian ini menunjukkan bahwa 3 servo dapat diimplementasikan pada robot hexapod dengan menggunakan algoritme pergerakan Alternating Tripod Gait. Hasil eksperimen menunjukkan bahwa hexapod dengan 3 servo yang telah dibuat dapat berjalan dengan kecepatan 0.047 m/s, lebih cepat 0.017 m/s daripada hexapod dengan 18 servo. Selain itu, bobot hexapod dengan 3 servo adalah 210 gram, jauh lebih ringan dibandingkan dengan hexapod 18 servo yang berbobot lebih dari 3 kg.

Abstrak: Robot is a tool that can interact with its environment and perform certain functions in accordance with a program that is embedded in it. To function properly, the robot needs to interact with its environment (sense), process the information (think), and give some responses (act). This study aims to integrate the three major functions in an hexapod fire-fighting robot. Input from the environment is obtained from range sensor. These inputs are then processed with a wall-following navigation algorithms and fuzzy logic to determine the direction or angle of motion. This angle is then implemented by the robot’s legs into some movement coordination by using tripod gait algorithm. This study has successfully integrate the algorithm of sensor data acquisition (sense), wallfollowing and fuzzy logic navigation system (think), and tripod gait coodination system (respon). The robot was tested in an environment in accordance with the provisions of KRPAI 2014, and it can move without hitting against the wall.

Abstrak: Bare-throathed whistler is one of several wild birds in Kelimutu National Park (TNKL) that is believed to have correlation with Lio Community‟s belief. The estimation of Bare-throated whistler‟s population in Kelimutu National Park was about 186.41-1668.07 individual by the density about 0.0389-0.3481 ind/ha with the sex ratio 6.2:1 that spreaded on area with height of 1100 – 1600 masl. The characteristic of Bare-throated whistler‟s habitat is a natural forest with various canopy level, high plant species diversity and high density. The habitat characteristics related to the availability of food in the form of insects, cover, safety and a nesting site. Generally the most of Lio community knew the existence of Bare-throated whistler directly or from their parents‟ stories. The perceptions of Lio Community to the Bare-throated whistler‟s existence is generally support the conservation efforts. The perceptions construct the Lio Community‟s atitude that tend to be conservative to the existence of Bare-throated whistler. The attitude shown by their behavior that not cathing the Bare-throated whistler from the TNKL‟s area or the outside. The attitude have an important role to the existence of Bare-throated whistler in Kelimutu National Park‟s area.
