    Automatic target detection radar requires adaptive thresholding achieved by the Constant False Alarm Rate (CFAR) circuit to control the false alarm caused by variations in the background clutter. This thesis deal with the problem that happened when an abrupt variation in background clutter merged with a multi-interfering target, and when the clutter cloud itself centered with multi-interfering targets. To detect targets in such environments, it needs a robust CFAR algorithm that excises the target spikes and clutter edges from the CFAR window to give the best possible estimation of the noise background. The Maximum Spike Subtraction MSS-CFAR family that uses two lock circuits to find two maximum spikes in the CFAR window that subtracted from sample summing to make better background noise estimation that used to construct an adaptive threshold. The MSS-CFAR family is MSS-CA�CFAR, MSS-GO-CFAR, and MSS-SO-CFAR, MSS-CFAR family in addition to two core algorithms were studied which are cell averaged CA-CFAR family that includes the greatest of GO-CFAR and smallest of SO-CFAR and ordered statistics OS-CFAR family that include greatest of ordered statistics OSGO-CFAR and the smallest of ordered statistics OSSO-CFAR. All these algorithms are simulated using MATLAB and applied them to three different clutter models that represent different environment cases. The CA-CFAR family failed to handle models two and three also OS-CFAR family except for OS-CFAR that handle all models successfully. For the MSS-CFAR family, MSS-CA-CFAR could handle all models successfully, and comparing with OS-CFAR, the MSS-CA-CFAR need less hardware and processing time because it did not need a sorting process that is essential for OS-CFAR. Therefore, the MSS-CA-CFAR is chosen to implement by practical digital circuit and there is another important feature in the MSS-CFAR algorithm that is parallel processing since the spike selection process is done at the same time with summing of samples process that makes this algorithm much less in processing time from any other algorithm using the same environment. The last MATLAB test for MSS-CA- vi CFAR with a spiky exponential model shown in Table 4.3 in chapter four shows clearly that MSS-CA-CFAR detects nine targets from ten that means the efficiency of detection of the proposed method is 90%. The field-programmable gate array FPGA chip that is used to implement the MSS-CA-CFAR algorithm needs only three signals from the radar receiver to match with the receiver circuit correctly which are time base clock signal period reset trigger signal and the pulse duration time

    PENGARUH KOMBINASI PAKAN FERMENTASI ASAL AMPAS TAHU, JAGUNG, DEDAK, DAN BUNGKIL KEDELAI DENGAN PENAMBAHAN MULTI ENZIM PENCERNAAN DAN VITAMIN E TERHADAP PENINGKATAN KADAR TESTOSTERON DAN KUALITAS SPERMATOZOA AYAM ARAB (GALLUS TURCICUS).

    MUSTAFA KAMAL Pengaruh Pemberian Kombinasi Pakan Fermentasi Asal Ampas Tahu, Jagung, Dedak dan Bungkil Kedelai Dengan Multi Enzim Pencernaan dan Vitamin E Dalam Ransum Terhadap Kualitas Spermatozoa dan Kadar Hormon Testosteron Ayam Arab. DASRUL dan M. AMAN YAMANPenelitian ini bertujuan untuk mengetahui pengaruh penambahan kombinasi pakan fermentasi asal ampas tahu, jagung, dedak, bungkil kedelai dengan multi enzim pencernaan dan vitamin E dalam ransum terhadap tampilan produksi, kualitas semen, dan kadar hormon testosteron ayam arab.Penelitian ini merupakan penelitian eksperimen dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari empat perlakuan dengan lima kali ulangan,yaitu 1) P0: ransum komersil (524), 2) P1: 83% ransum komersial + 10% pakan fermentasi + 0,15% multi enzim+ 0,02% vit E, 3) P2: 79,83% ransum komersial + 20% pakan fermentasi + 0,15% multi enzim+ 0,02% vit E, 4) P3: 69,83% ransum komersial + 30% pakan fermentasi + 0,15% multi enzim+ 0,02% vit E. Semua perlakuan diberikan selama 35 hari. Pengukuran kualitas spermatozoa dilakukan dengan metode yang dilakukan diBIB lembang dan kadar hormon testosteron dilakukan dengan menggunakan enzyme_linked immunosorbent assay (ELISA). Data yang diperoleh dianalisis menggunakan analisis of variance (ANOVA) yang dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa pemberian kombinasi pakan fermentasi asal ampas tahu, jagung, dedak dan bungkil kedelai dengan multi enzim pencernaan dan vitamin E dalam ransum tidak berpengaruh secara nyata (P>0,05) terhadap pH, bau dan konsistensi semen, namun berpengaruh secara nyata (

    ABB as one of the leading power and automation company is connecting millions of electrical devices and systems to industrial internet of things called ABB Ability(TM). ABB Ability(TM) is refining the measured real-time data with calculations to additional soft sensors signals and Key Performance Indicators (KPIs) at the various levels from the system edges to central cloud. The engineering of the calculations requires web based Integrated Development Environment (IDE) that provides good developer experience for the subject matter experts to be productive in their work. This thesis aims to construct a user interface for ABB calculation engine that will help subject matter expert to work on the calculation engine more efficiently. As the output of this thesis work, a web-based IDE is developed on top of ABB's internal front end dashboard framework. The developed user interface lets user to operate the calculation engine more efficiently and follows their natural work flow

    EVALUASI KEBUTUHAN PARKIR RUMAH SAKIT IBU DAN ANAK (RSIA) MILANO TELUK KUANTAN (STUDI KASUS : KELURAHAN SIMPANG TIGA, KECAMATAN KUANTAN TENGAH, KABUPATEN KUANTAN SINGINGI)

    Dalam penelitian ini dilakukan evaluasi terhadap kapasitas ketersediaan ruang parkir di RSIA Milano yang berada di Jalan Perintis Kemerdekaan Kelurahan Simpang Tiga Teluk Kuantan serta memberikan penanganan atau solusi nantinya apabila kendaraan melebihi kapasitas ruang parkir yang tersedia. Adapun metode analisis parkir yang digunakan oleh peneliti adalah metode yang umum digunakan untuk menentukan kebutuhan lahan parkir yaitu metode berdasarkan selisih terbesar antara kedatangan dan keberangkatan kendaraan parkir dalam interval waktu tertentu. Hasil analisis kebutuhan parkir selama 3 hari pengamatan di dapat kebutuhan SRP untuk sepeda motor yaitu 58,13 SRP, sedangkan ruang parkir yang tersedia sebanyak 52 SRP, jadi kekurangan SRP berdasarkan analisis kebutuhan ruang parkir sebanyak 6,13 SRP atau 7 SRP. Sedangkan kebutuhan SRP untuk mobil yaitu 31,13 SRP, ruang parkir yang tersedia sebanyak 40 SRP, jadi kelebihan SRP mobil yang tersedia berdasarkan analisis kebutuhan ruang parkir sebanyak 4,74 SRP atau 5 SRP. luas lahan yang dibutuhkan untuk rencana penambahan ruang parkir sepeda motor  yang kurang sebanyak 7 SRP adalah 3 m2 x 7 = 21 m2
