Customer Satisfaction Analysis in the Healthcare Industry Using KANO Method and Importance Performance Analysis
Customer satisfaction is one of the most important aspects in the business world, especially in the service sector because it can increase customer loyalty, and create a positive image for the company and ultimately contribute to long-term success. This study was conducted at MEDCORP, a company engaged in the healthcare industry, which seeks to increase sales by improving customer service. To measure and customer satisfaction, this study uses 5 Dimensions of service quality, namely reliability, responsiveness, assurance, empathy and direct evidence. The methods used are the IPA and KANO methods. The IPA method uses data from customers to evaluate how important each attribute is and how well the company meets those expectations. The KANO method identifies attributes that can increase customer satisfaction if added or improved. This combination provides a more comprehensive understanding of customer needs and product performance that can be used as a reference for companies in achieving the service desired by customers, so that it can increase sales and customer satisfaction. Based on the results obtained, it is known that there are 23 negative gaps, so further analysis is carried out to determine the strategy set. The author makes three types of strategies that can be implemented, namely the main, middle, and final priority strategies based on the IPA-KANO integration classification. Through this research, it is expected to be used as a consideration for business actors or managers in determining improvements in service quality through continual improvement of MEDCORP's performance so that service quality and output become better
Linking Carbonate Facies to Stylolite Distribution of Middle Jurassic Limestone, Onshore Abu Dhabi Oil Field
This study examines the relationship between facies and stylolitization in the Upper Araej Member carbonates of onshore Abu Dhabi. Analysis of core and thin sections identified four facies: wispy-laminated skeletal wackestone (F-1), peloidal skeletal mud-dominated packstone (F-2), coated-grain skeletal grainstone (F-3), and peloidal skeletal floatstone (F-4), deposited across a shallow carbonate ramp. Stylolites were described and measured for vertical offset amplitude to assess facies dependence. Results show facies-related tendencies in stylolite amplitude and morphology. Mud-supported facies (especially floatstones and wackestones) tend to display higher variability, with floatstones reaching amplitudes of up to 20 mm, whereas grainstones may also contain isolated high-amplitude stylolites (up to 14 mm). Packstones and wackestones, by contrast, rarely exceed 10-13 mm. Boxplots highlight greater variability in mud-rich facies, whereas grainstones exhibit narrower distributions. Statistical testing (ANOVA, p = 0.109; Kruskal–Wallis, H = 3.38, p = 0.34) indicates no statistically significant differences in mean stylolite amplitude across facies, although descriptive data reveal trends in variability and extremity. Jagged stylolites occur in both mud-rich and grain-supported facies, whereas wispy seams are strongly associated with micrite-rich facies and are largely absent in grainstones. Stylolites in these carbonates may act as both vertical barriers and localized porosity enhancers. Their facies-associated occurrence emphasizes the need to integrate stylolitization into reservoir models to better predict connectivity, compartmentalization, and flow behavior in Middle Jurassic carbonates

Pengembangan Filter Adaptif Berbasis Least Mean Square untuk Pengurangan Noise pada Sinyal Elektrokardiogram
Electrocardiogram (ECG) signals are often affected by various types of noise, such as electromagnetic interference, patient body movement, and disturbances from other medical devices, which can degrade the signal quality and hinder accurate detection of heart disorders. This study aims to compare the performance of various filters in reducing noise in ECG signals, focusing on the Highpass-Lowpass filter and the Least Mean Square (LMS) adaptive filter. The testing was conducted using metrics such as Mean Squared Error (MSE), Signal-to-Noise Ratio (SNR), average amplitude, total error, and computation time. The experimental results show that the LMS filter provides the best results, with an MSE value of 0.0045, SNR of 21.5 dB, and total error of 4.78, indicating its ability to produce a cleaner signal compared to the Highpass-Lowpass filter. The LMS filter also demonstrates good computational efficiency, with a time of 0.102 seconds. With its ability to dynamically adjust filter parameters, the LMS filter proves effective in reducing both low and high-frequency noise in ECG signals. This study shows that the LMS filter can be effectively applied to process ECG signals contaminated by noise and contributes to improving the accuracy of heart disorder diagnosi

Penerapan Kendali Logika Fuzzy pada Proses Pendinginan Panel Surya
Salah satu faktor yang dapat mempengaruhi kinerja panel surya selain radiasi matahari, dan juga kondisi lingkungan sekitar panel adalah suhu. Panel surya akan menerima panas yang berasal dari radiasi matahari, sehingga menyebabkan suhu pada panel meningkat melebihi nilai suhu optimal yang disarankan dan kondisi ini menyebabkan kinerja dan juga efisiensi dari sel surya turun drastis. Setiap kenaikan suhu panel surya sebesar 1 ℃ dari 25℃ akan mengakibatkan pengurangan daya keluaran yang dihasilkan sebesar kisaran 0,4-0,5 %. Sistem pendingin air aktif merupakan salah satu dari beberapa teknologi yang telah terbukti mampu mengurangi kehilangan panas dan meningkatkan energi listrik pada modul fotovoltaik (PV). Penerapan kendali logika fuzzy pada sistem pendingin panel surya berbasis air menghasilkan perolehan energi bersih yang lebih unggul sebesar 43,90Wh atau meningkat sebesar 13,55% jika dibandingkan proses pendinginan tanpa memasukan kedali logika fuzzy dimana perolehan energi bersihnya berkurang sebesar 9,72%. Nilai efisiensi yang dihasilkan dari proses pendinginan dengan penerapan kendali logika fuzzy sebesar 20,33% lebih besar jika dibandingkan dengan proses pendinginan tanpa logika fuzzy yaitu 19,56%
