Abstract

Cholecystitis is an inflammation of the gallbladder. The gallbladder is an organ where bile is stored, which is a fluid that plays an important role in the digestion of fat in the body. Data processing at Bangkatan Hospitals is currently still done by means of patients coming to the hospital and heading to the receptionist to carry out the process before meeting an expert (doctor), it makes patients have to queue and wait their turn to meet the doctor. The current lack of knowledge and information from the community/patients causes delays in handling the early symptoms of cholecystitis. This makes this research carried out by building an expert system that is able to diagnose cholecystitis. With the dempster shafer method, it is expected to be able to provide a high level of accuracy. From the calculation process using the Dempster Shafer method, it can be concluded that the disease suffered by the user is Acute Cholecystitis with a density value of 0.571 or 57.1%.

Abstract

One of the keys to ensuring optimal radar performance in various applications, from security to navigation, is a high target detection probability. This paper uses a multiple-signal-classification (MUSIC) algorithm to increase the detection probability which is implemented on a MIMO radar with subarrays in the transmit (Tx) and receiver (Rx) antenna array elements called the SMIMO radar. The subarray method on this radar is known to increase the angular resolution of detection, expand the detection range, add virtual arrays, and minimize the influence of interference compared to conventional radars such as phased-array and MIMO radars. The evaluation and effectiveness of the detection probability performance of this radar are compared to previous radars by considering the number of Tx-Rx antenna elements, the number of subarrays in Tx-Rx, false alarm probability, and SNR variations. SMIMO radar with the MUSIC algorithm and Tx-Rx subarrays demonstrates superior detection performance at low SNR, achieving a Pd of 0.9 at SNR -24.4 dB and outperforming PhA, MISO, and MIMO radars. Increasing Tx subarrays (W) significantly enhances detection capabilities, with ROC analysis showing Pd above 0.92 at Pfa around 10?² and SNR above -15 dB, making it highly effective for weak signal detection.

Abstract

One of the nursing problems that often arise in postoperative sectio caesarea patients is an acute inflammatory process and pain that causes discomfort and results in limited movement. One of the non treatments such as lemon aroma therapy, acupressure, guided imagery, autogenic therapy, progressive relaxation therapy, meditation, music therapy and complementary therapy Biologic Nurturing Baby Led Feeding. This study aimed to analyze the effect of Biologic Nurturing Baby Led Feeding on reducing maternal pain post sectio caesarea at Asy-Syifa Medika Tulang Bawang Barat Hospital. This type of research was quantitative research, using pre-experimental using one group pretest-posttest research design. The population in this study was the entire number of sectio caesarea patients at Asy-Syifa Medika Hospital on June 17 - July 21, 2024 there were 30 people. The sampling technique in this study used saturated sampling technique. The Wilcoxon Test result showed a comparison of the pain scale before and after the intervention of Biologic Nurturing Baby Led Feeding with a p-value (0,000) (p-value<0,05), so statistically there is a significant difference in pain scale in Post Sectio Caesarea mothers before and after the intervention of Biologic Nurturing Baby Led Feeding.

Abstract

Perifiton merupakan organisme yang hidup menempel pada substrat seperti tumbuhan, kayu, hewan, dan batu. Tujuan dari penelitian ini yaitu untuk mengetahui komposisi dan kelimpahan perifiton di Sungai Desa Sengawang Kabupaten Sambas. Penelitian ini dilaksanakan pada bulan Februari - April 2025 di Sungai Desa Sengawang, Kabupaten Sambas, dan mengunakan metode purpossive sampling. Pengambilan sampel perifiton dilakukan dengan mengerik seluruh permukaan substart tumbuhan. Komposisi perifiton epifitik yang ditemukan di Sungai Desa Sengawang 21 genera yang berasal dari 3 kelas yaitu Bacillariophyta 80,42%, Chlorophyta 12,26%, dan Cyanophyta 7,33%. Kelimpahan perifiton distasiun 1 sejumlah 6416 sel/cm², stasiun ke 2 dengan kelimpahan terendah sejumlah 2168 sel/cm², dan kelimpahan tertinggi pada stasiun 3 sejumlah 14,202 sel/cm².

Abstract

Penelitian ini menggunakan desain mixed methods sequential explanatory untuk memahami proses terbentuknya minat berkuliah calon mahasiswa di Universitas Nusa Putra Sukabumi. Pada fase kuantitatif, survei terhadap 163 calon mahasiswa menguji pengaruh lokasi dan reputasi terhadap minat berkuliah menggunakan analisis regresi linear berganda. Hasil uji parsial menunjukkan bahwa lokasi (t=1,084; p=0,280) dan reputasi (t=−0,556; p=0,579) tidak berpengaruh signifikan terhadap minat berkuliah secara individual. Pada fase kualitatif, wawancara grounded theory terhadap 13 calon mahasiswa mengungkapkan mekanisme proses keputusan yang lebih kompleks. Analisis axial coding mengidentifikasi fenomena inti: minat berkuliah terbentuk melalui proses negosiasi rasional-emosional di mana calon mahasiswa menimbang berbagai pertimbangan (lokasi, biaya, akreditasi, fasilitas, diferensiasi) sambil mencari rasa "cocok" (fit) yang diperkuat oleh validasi informasi. Integrasi kedua fase mengungkapkan bahwa lokasi dan reputasi muncul dalam narasi calon mahasiswa namun bekerja sebagai "filter baseline" bukan penentu utama. Faktor emosional, dukungan sosial, dan pencarian bukti empiris tentang prospek karier menunjukkan relevansi yang lebih kuat. Temuan ini menunjukkan pentingnya universitas untuk merancang strategi komunikasi yang merespons setiap tahap perjalanan keputusan calon mahasiswa, bukan hanya fokus pada positioning reputasi atau aksesibilitas lokasi. Kontribusi teoretis menunjukkan bahwa model student college choice perlu mengintegrasikan dimensi proses keputusan yang dinamis dan kontekstual.
