Passenger Station

This study intends to determinate criteria of the station location which the aim is to providing input in the policy that criteria. The priority of creteria and sub criteria the station location is determinated by using Analytical Hierarchy Process (AHP). Based on processing and analysis of data are obtained the aspect of regulation is more priority than other criteria in determining the railway passenger station location. The other aspects are of the economic environment, accessibility and connectivity, as well as operational. For sub-criteria, the suitability of the national railway master plan (Ripnas) is more priority than land-use aspects (spatial plan). For Sub-economic criteria, the first aspect is the economic potential in the region/ growth area. For sub accessibility and connectivity criteria consider about distance within the downtown stationKey words: criteria, passenger station Kajian ini bermaksud menyusun kriteria penetapan lokasi stasiun kereta api pen um pang dengan tujuan memberikan masukan dalam kebijakan kriteria penetapan lokasi stasiun kereta api penumpang. Dengan menggunakan Analytical Hierarchy Process (AHP) maka akan ditentukan prioritas dari kriteria dan sub kriteria untuk penentuan lokasi stasiun. Dari pengolahan dan analisis data diperoleh hasil bahwa aspek regulasi merupakan prioritas utama dalam penentuan lokasi stasiun penumpang kereta api, diikuti oleh aspek lingkungan ekonomi, aksesibilitas dan konektivitas, serta operasional. Untuk sub kriteria, kesesuaian rencana induk perkeretaapian nasional (Ripnas) sebagai prioritas dibandingkan aspek tata guna lahan (rencana tata ruang wilayah). Sub kriteria ekonomi yang menjadi urutan pertama adalah potensi ekonomi di wilayah/kawasan pertumbuhan. Untuk sub kriteria aksesibilitas dan konektivitas adalah pertimbangan jarak stasiun dengan pusat kota.Kata kunci: kriteria, stasiun penumpang

The most prevalent cancer that threatens women’s life is Breast cancer. According to WHO Statistics in 2020, 2.3 Million Women were diagnosed with Breast cancer and 685000 death rate were disclosed globally. In this paper, Wearable Health Diagnosis System (WHDS) based antenna for the identification of the early breast cancer is discussed. Conventional methods are limited by their uncomfortable testing setups, panic environment and failure in results. Recently, textile based antenna for microwave imaging stared to work on the detection of the cancer cells at the earlier stage in breast. WHDS antenna has the requirements of wider bandwidth, high resolution, low Specific Absorption Rate (SAR), bio compatibility, and flexibility. The proposed work is based on the textile antenna using Denim substrate (permittivity = 1.67, thickness = 2 mm) to diagnosis the Early Breast Cancer Tissues (EBCT). Using the following antenna parameters (return loss, E-filed, H-field and SAR values), the position and malignancy of the EBCT is identified. Since the dielectric properties of the cancer cells are high, the influence of the effective permittivity is higher on the E-field and SAR. Along with the above parameters, comparison of various substrate materials (Denim, FR4, and RT duroid) were also tested and Denim is selected for our application as it introduces greater reflection co-efficient and wider bandwidth. The proposed antenna is designed to operate at a frequency of 2–4 GHz. This miniaturised antenna has a volume of 30 × 28 × 2 mm3.
