"[ ABSTRAK
Antena mikrostrip saat ini banyak diaplikasikan dalam dunia telekomunikasi. Antena mikrostrip sendiri memiliki beberapa kelebihan jika dibandingkan dengan antena jenis lain, yaitu bentuknya yang tipis dan kecil, memiliki bobot yang ringan, mudah untuk difabrikasi, serta harga yang relatif murah. Berangkat dari keperluan untuk melakukan penelitian dengan tujuan mengetahui tingkat kematangan buah-buahan dengan menggunakan antena, maka dilakukan uji coba menggunakan antena mikrostrip serta melakukan pengujian terhadap nilai koefisien transmisi dan refleksi untuk memperoleh data yang nantinya dapat digunakan untuk pengembangan alat serta teknologi lebih lanjut.
Koefisien transmisi dan refleksi ini bisa terjadi ketika propagasi gelombang elektromagnetik mengenai yang sebuah benda. Data hasil pengukuran nilai koefisien transmisi dan refleksi akan diperoleh dengan menggunakan antena mikrostrip serta Network Analyzer (NA) di dalam alat berwujud waveguide. Dengan parameter pengukuran meliputi jarak, posisi, nilai parameter S11, S21 permitivitas dan jenis bahan.
Pada skripsi ini telah dilakukan pengukuran data dengan membandingkan parameter S21 pada antena mikrostrip dengan beberapa variasi jenis benda yaitu, buah labu, buah semangka, balon garam dan balon gula. Dari hasil pengukuran diketahui bahwa nilai S21 yang paling tinggi dimiliki oleh buah labu matang nilai S21 sebesar -32,9 dB, pada buah semangka matang nilai S21 sebesar -39,7 dB, balon air garam S21 sebesar -43,52 dB, balon gula S21 sebesar -48,56 dB, labu mentah -50.09 dB dan semangka mentah -52.22 dB. Dari beberapa data pengukuran diatas, dapat diambil kesimpulan bahwa semakin rendah nilai kepadatan dan kerapatan benda uji, semakin kecil nilai koefisien transmisi dan refleksi. Dari hasil penelitian berikut ini diharapkan dapat digunakan untuk pengembangan alat pada masa yang akan datang, serta metode alternatif untuk mendeteksi tingkat kematangan buah dengan memanfaatkan antena mikrostrip serta nilai koefisien transmisi dan refleksi.

"Sebuah radio menggunakan gelombang elektromagnetik untuk mengirim informasi di udara. Ini dicapai dengan menghasilkan sinyal listrik yang bergerak bolak-balik, atau berosilasi, dengan kecepatan tinggi. Tingkat di mana sebuah sinyal radio berosilasi bolak-balik disebut frekuensi dan diukur dalam satuan Hertz. Pemancar radio dasar adalah sebuah sistem yang digunakan untuk memproduksi dan memperkuat sinyal radio, penggabungan, atau termodulasi, dengan sinyal suara dari mikrofon. Sinya radio yang termodulasi dikirim ke sebuah antena, yang memancarkan sinyal keudara. Sinyal yang memancar diterima oleh antena dan dikirim kebagian penerima. Disana sinyal radio diproses kembali ke sinyal audio asli, sehingga pesan suara yang asli dapat didengar. Modulator FSK merupakan teknik modulasi yang telah lama dikenal di dunia telekomunikasi, yang menjadi berbeda pada skripsi ini adalah pada aplikasinya. Komunikasi radio 2 arah trunking menggunakan modulasi FSK untuk komunikasi data. Analisis di buat untuk mengetahui luas cakupan area dari komunikasi radio 2 arah yang menggunakan modulasi FSK yang di aplikasikan sebagai komunikasi data. Dan kesimpulan yang dapat di ambil adalah luas cakupan area komunikasi data lebih kecil dibandingkan komunikasi suara.

A radio uses electromagnetic waves to send information through the air. This is accomplished by generating electrical signals that move back and forth, or oscillate, with a high speed. The rate at which a radio signal to oscillate back and forth is called the frequency and is measured in Hertz. Basic radio transmitter is a system that is used to produce and strengthen radio signals, merging, or modulated, with the voice signal from the microphone. Modulated radio fractions were sent to an antenna, which transmits signals keudara. Radiated signal is received by the antenna and sent goto the recipient. There processed radio signal back to the original audio signal, so that the original voice message can be heard. FSK modulator is a modulation technique that has long been known in the telecommunications world, which is different in this thesis is on the application. 2-way radio communications trunking using FSK modulation for data communication. Analysis is made to find broad coverage area of two-way radio communication using FSK modulation which is applied as data communications. And the conclusions that can be taken is the area of data communications coverage is smaller than voice communication."

"Skripsi ini membahas tentang perancangan sistem SCADA (Supervisory Control and Data Acquisition) pada sebuah miniatur warehouse. Pada perancangan sistem ini digunakan PLC (Programmable Logic Controller) Omron CJ1M sebagai RTU (Remote Terminal Unit) yang mengambil data sensor dan unit-unit beban kemudian menyampaikannya pada MTU (Master Terminal Unit) yang terdiri dari HMI (Human Machine Interface) SCADA.
Pada skripsi ini dirancang sistem SCADA sederhana untuk mengawasi dan mengontrol unit-unit beban dan sensor yang ada dalam miniatur warehouse, yaitu lampu dan fan serta sensor smoke detector dan motion sensor. Kemudian untuk HMI SCADA akan dibuat dengan bahasa pemrograman Visual Basic 6.0 dengan Microsoft Access 2007 sebagai media penyimpanan database-nya.
Pada perancangan HMI SCADA terdapat beberapa mode yaitu local dan remote. Mode local digunakan untuk mengontrol unit-unit beban dari miniatur warehouse dan mode remote digunakan untuk mengontrol unit-unit beban dari HMI SCADA / Laptop. Untuk pengujian sistem dilakukan pengukuran waktu respon dari HMI SCADA terhadap miniatur warehouse dan begitu juga sebaliknya.
Dari pengujian tersebut dapat disimpulkan bahwa pada mode local waktu respon terhadap miniatur warehouse lebih cepat dibandingkan mode remote dan waktu respon terhadap HMI SCADA lebih lama dibanding mode remote. Lalu untuk mode remote waktu respon terhadap miniatur warehouse dan HMI SCADA hampir sama.

This thesis discusses the design of SCADA systems (Supervisory Control and Data Acquisition) on a miniature warehouse. In designing this system is used PLC (Programmable Logic Controller) Omron CJ1M as RTU (Remote Terminal Unit) which takes sensor data and load units then pass them on to the MTU (Master Terminal Unit) consisting of HMI (Human Machine Interface), SCADA.
In this paper designed a simple SCADA system for monitoring and control units and sensors of existing loads in the miniature of warehouse, which is light and fan and smoke detector sensors and motion sensors. Then for SCADA HMI will be created with Visual Basic 6.0 with Microsoft Access 2007 as database storage media.
In SCADA HMI design, there are several modes of local and remote. Local mode is used to control the load units from the warehouse miniature and the remote mode is used to control the load units from SCADA HMI / Laptop. To test the system response time measurements from SCADA HMI on the warehouse miniature and vice versa.
From these tests we can conclude that the local modes of warehouse miniature response time is faster than remote mode and time of the response to be longer than SCADA HMI remote mode. Then for remote mode response time to warehouse miniature and SCADA HMI is almost the same.
