Energi berkesinambungan untuk perangkat elektronik bergerak selalu dibutuhkan selama kapasitas penyimpanan energi dari baterai di perangkat elektronik bergerak tersebut terbatas untuk beberapa jam waktu pemakaian saja. Untuk mendapatkan waktu operasi yang panjang dari perangkat elektronik bergerak, sumber energi seharusnya dihubungkan selalu ke perangkat tersebut. Pada makalah ini, kami mengajukan metode pengisian energi melalui operasi nirkabel menggunakan gelombang mikro (RF) yang diradiasikan dengan multi frekuensi kerja di udara. Rangkaian penyearah dari RF ke DC merupakan komponen utama untuk mengubah gelombang RF ke arus elektronik (DC). Model Dickson digunakan sebagai pendekatan dengan keuggulannya antara lain rangkaian yang sederhana, faktor ripple DC yang rendah, dan lain lain. Desain, analisis, dan eksperimen dari rangkaian penyearah tersebut telah dilakukan dan dipaparkan pada makalah ini. Pada pengukuran, perangkat elektronik bergerak diletakkan dengan jarak sekitar 5 meter dari sumber energi, tegangan DC sebesar 3,7 V telah diperoleh pada frekuensi kerja 825-960 MHz dengan nilai PCE 12-33% dan faktor ripple sebesar ± 0.01%. Waktu pengisian energi sekitar 4 jam pada ruang percobaan dan sekitar 11 jam di luar ruangan telah diobservasi. Berdasarkan hasil tersebut, metode pengisian energi secara nirkabel untuk perangkat elektronik bergerak merupakan kandidat yang potensial untuk menyelesaikan masalah energi berkesinambungan dan mendukung sebagian program teknologi hijau.

The automatic system satellite signal strength tracking model through the positioning of the receiving antenna is one way to reduce the problem of attenuation and signal strength instability which is quite influential in tracking the satellite orbit position. The method of applying the antenna movement technique by adjusting the azimuth and elevation angles is possible to detect the position of the satellite orbit trajectory accurately. Therefore, the expected goal is to know the existence of the satellite's orbital trajectory and ensure that the signal strength it transmits will always be stable in all conditions. The empirical quantitative method is used to support the achievement of these objectives where the technique is carried out through field observations and device design involving calculations and applied mathematical equations based on information on satellite position data as a tracking object as well as a source of signal strength. Based on the test results, it shows that all the positions of the tracked satellite orbital trajectories produce a minimum and maximum azimuth-elevation angle of 0.52% - 4.02% and 0.25% - 3.99% when the system detects NSS6. Furthermore, when the system detects Palapa D, the minimum values for the percentage of maximum deviation error are 0.6% and 4.67% with a tolerance of the alignment angle to the satellite of 20. Overall, the designed system is able to track the position of the satellite's orbit path based on the level of signal strength stability on the parabolic receiver antenna which is designed with a small percentage of angle error.

Peningkatan kuantitas dan kualitas sinyal sudah merupakan suatu keharusan bagi perusahaan penyedia jasa telekomunikasi untuk terus mempertahankan atau menambah pelanggannya. Kuantitas dan kualitas sinyal sangat dipengaruhi oleh besarnya cakupan yang dihasilkan oleh daya pemancar (BTS). Penguatan kanal pilot (PICH gain) adalah satu hal yang sangat mempengaruhi keluaran dan pemfokuskan daya dalam menghasilkan cakupan sinyal lebih optimal dimana salah satunya dipengaruhi oleh pengendalian sudut kemiringan antena. Namun demikian keduanya memiliki pengaruh yang baik dan buruk terhadap cakupan itu sendiri atau pada kanal-kanal lain dalam jaringan CDMA 2000 1X. Perbandingan hasil simulasi dari kedua perubahan tersebut yang akan menjadi inti dari penelitian ini, terutama terhadap nilai cakupan Ec/Io yang menunjukan kualitas sinyal dan cakupan Rx level yang menunjukan kuantitas terhadap perubahan sudut kemiringan antena. Adapun hasilnya menunjukkan bahwa sudut kemiringan semakin diperbesar akan menghasilkan PICH gain semakin besar yaitu terapai saat kemiringan 60 dapat menghasilkan penguatan sebesar 243 dBm atau 10023.74467 mW.
