"Penelitian ini menggunakan metode Ambient Noise Tomography (ANT) untuk menggambarkan model kecepatan grup gelombang Rayleigh pada bagian kerak atas Pulau Jawa yang memiliki kondisi tektonik yang kompleks. Data penelitian yang digunakan merupakan data waveform komponen vertikal dari 99 jaringan sensor seismik stasioner BMKG yang tersebar di Pulau Jawa pada tahun 2021. Pengolahan data waveform dilakukan mulai dari single data preparation, cross correlation dan stacking, analisis cross correlogram, pengukuran kurva dispersi, tomografi kecepatan dan yang terakhir adalah interpretasi hasil penelitian. Hasil inversi menghasilkan citra tomografi kecepatan grup gelombang Rayleigh pada kerak atas di wilayah Pulau Jawa berkisar antara 1,88 km/s hingga 2,60 km/s dan umumnya meningkat dengan bertambahnya periode pengukuran di wilayah Pulau Jawa. Penelitian ini berhasil mengidentifikasi patahan – patahan dan zona gunung api di Pulau Jawa dengan jelas yang berada pada wilayah batas kontras zona anomali kecepatan rendah dan zona anomali kecepatan tinggi.......This study uses the Ambient Noise Tomography (ANT) method to describe the velocity model of the Rayleigh wave group in the upper crust of Java Island which has complex tectonic conditions. The research data used is vertical component waveform data from 99 BMKG stationary seismic sensor networks distributed on Java Island in 2021. Waveform data processing is carried out starting from single data preparation, cross correlation and stacking, cross correlogram analysis, dispersion curve measurements, velocity tomography and the last is the interpretation of the research results. The inversion results produce a tomographic image of the Rayleigh wave group velocity in the upper crust in the Java Island region ranging from 1.88 km/s to 2.60 km/s and generally increases with increasing measurement period in the Java Island region. This research has succeeded in clearly identifying faults and volcanic zones in Java Island which are located in the contrasting boundary of the low velocity anomaly zone and the high velocity anomaly zone."

"WLAN and WiMAX frame structures are preceded by preamble signals. They have some similarities such as consisting of two adjacent signals with repetition patterns. Therefore, this paper introduces a joint detection of WLAN and WiMAX preambles using a common circuit. Time domain detection is proposed in order to avoid FFT involvement that can increase the system complexity and latency. The proposed system is constructed from repetition based auto-correlation and cross-correlation with resources sharing that has lower complexity than the conventional one. Moreover, the fixed point simulation shows that the proposed circuit has satisfied the receiver minimum sensitivity requirements for both WLAN and WiMAX standards."

"The nearshoreis known as the dynamic zone which characterized by a dynamic interaction between waves and underlying bathymetry.The characteristic of bathymetry and its evolution are very important for coastal engineering applications and development......"

"Peluncuran Kartu Jakarta Sehat (KJS) pada November 2012, sebagai pilot project ke enam kelurahan yang kemudian didistribukan ke seluruh wilayah DKI Jakarta, mengakibatkan lonjakan kunjungan pasien di banyak fasilitas kesehatan, terutama di RSUD DKI Jakarta. Program KJS memberikan kemudahan bagi warga DKI untuk berobat secara gratis, baik untuk perawatan di Instansi Gawat Darurat (IGD), rawat inap maupun rawat jalan. Keuntungan tersebut tak heran menyebabkan persoalan seperti pasien harus mengantre lama di loket pendaftaran, ruang pemeriksaan (poli rawat jalan) maupun ruang pengambilan obat (apotek). Tak hanya itu, tidak sedikit pasien harus sulit mendapatkan kamar rawat inap sehingga harus bertahan di IGD. Distribusi KJS pun menimbulkan pertanyaan apakah KJS memang diberikan kepada warga miskin/rentan miskin? Sebab, tidak sedikit warga kaya, tingkat penghasilan gaji relatif tinggi ataupun memiliki aset kekayaan lain, yang mendapatkan KJS tersebut. Tak hanya itu, beberapa warga yang telah memiliki jaminan kesehatan lain, seperti Askes atau asuransi swasta juga menggunakan KJS tersebut dengan alasan gratis. Penelitian ini bertujuan untuk mengevaluasi program KJS yakni berupaya untuk menganalisis kesesuaian target penerima KJS yang berobat ke RSUD DKI Jakarta, menganalisis penilaian pasien KJS terkait pelayanan KJS di RSUD DKI Jakarta serta mengetahui faktor-faktor apa yang dapat berhubungan dengan penilaian pasien tersebut, seperti usia, jenis kelamin, pendidikan, penghasilan gaji responden dan kepemilikan aset responden. Peneliti melakukan penelitian di tujuh RSUD DKI Jakarta selama Mei 2014 hingga Februari 2015. Peneliti mencatat, sebanyak 6,00% menilai pelayanan KJS buruk (tidak baik), sebanyak 71,75% responden menilai pelayanan KJS kurang baik, sebanyak 20,75% menilai pelayanan KJS sudah baik dan hanya 1,50% menilai pelayanan KJS baik sekali Penilaian mencatat, faktor usia, pendidikan, jenis kelamin signifikan berkorelasi terhadap penilaian responden tersebut, sedangkan penghasilan gaji responden tidak signifikan berkorelasi.......The launch of Jakarta Health Card (Kartu Jakarta Sehat/KJS) in November 2012, as a pilot project of six villages later distributed to all areas of Jakarta, gives impact to patients visit in many health facilities, especially in District General Hospital of DKI Jakarta. KJS program ease Jakarta citizens to get free medication treatment in Emergency Room (ER), inpatient and outpatient. Patients do not have to queue in making registration at Poly Clinic and also Pharmacy. Patients sometimes face difficulties in getting room hospital therefore patients have to wait in Emergency Room (ER). A question raises whether KJS Distribution appropriately received by poor patient/vulnerable poor? Some rich patients, with relatively high income and having other property assets, also received KJS. Not only that, some patients who already have other health insurance, such as ASKES or private insurance also use the pretext of KJS free. This study aimed to evaluate the program KJS which seeks to analyze the suitability of the target beneficiaries of KJS, to analyze patient assessment KJS related services KJS in RSUD DKI Jakarta and to know what factors that can correlate the assessment of the patient, such as age, sex, education, income and asset ownership respondents. Researchers conducted a study in seven of District General Hospital (RSUD/RSKD) of DKI Jakarta during May 2014 to February 2015. The researchers noted, as much as 6.00% rate assess the service KJS bad, as many as 71.75% of respondents rate assess the service KJS is not good, as much as 20.75% assess KJS service is good and only 1.50% rate assess this excellent service KJS such assessment may be influenced by factors such as age, sex, education and income respondents. From these factors, age, sex, education are significantly correlated but income respondent is not significantly correlated."
