Judul: The Impact of Digital Application to Customer Experience, Customer Satisfaction and Customer Loyalty in A Life Insurance Company
Abstrak: Technological developments have transformed the traditional insurance business into a digital-based business also known as digital transformation, started from insurance offerings and sales to after-sales services. XYZ Insurance has used a digital system from end to end for selling their products. It has also developed e-Commerce distribution channels and provided eXYZ application for self-servicing their customers. Since 2016, XYZ Insurance has measured customer satisfaction using a CXI value but it has not shown the relationship of using self-servicing digital application to customer satisfaction. This research will examine the impact of usage of digital applications on customer experience, customer satisfaction, and customer loyalty at XYZ Insurance. The research is used non-probability sampling with the quota sampling method by taking survey from 203 respondents who have used the features in the eXYZ application at least 2 times,. The specified sample criteria are customers who have used the eXYZ application at least twice since downloading the application. In this research, with an expected error rate of 5%, the number of samples required is 349, from a population of 3800 customers. then the data is processed using SEM PLS. From this research it was concluded that usage of digital applications has a significant relationship and has a positive impact on customer experience, customer experience has a significant and a positive impact on customer satisfaction, customer experience does not have a direct positive impact on customer loyalty but it has indirect impact through customer satisfaction, and customer satisfaction has a significant and a positive impact on customer loyalty. The most important factors for customers when using digital applications are digital application innovation, the convenience, and perceived value to customers.

Judul: The Effect of Digital Service Quality Satisfaction on Bank Muamalat Indonesia Customer Loyalty
Abstrak: Adanya pelayanan secara digital atau salah satunya mobile banking merupakan suatu solusi yang tepat untuk menghadapi persaingan dalam industri perbankan. Dengan banyaknya keunggulan yang dimiliki dari mobile banking, Bank Muamalat Indonesia turut serta mengadopsi manfaat aplikasi tersebut guna meningkatkan performa kualitas Bank Muamalat Indonesia. Namun laporan survei menunjukkan bahwa peforma kinerja pada layanan digital di Bank Muamalat Indonesia lebih rendah daripada pelayanan digital perbankan syariah lainnya. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi kepuasan nasabah terhadap layanan digital serta pengaruhnya terhadap loyalitas nasabah Bank Muamalat Indonesia. Pengukuran kepuasan nasabah menggunakan konsep UTAUT 2 (Unified Theory of Acceptance and Use of Technology). Metode yang digunakan dalam penelitian ini adalah SEM-PLS. Hasil analisis SEM-PLS menunjukkan variabel effort expectancy, social influence, facilitating conditions, dan habit masing-masing berpengaruh secara signifikan terhadap user satisfaction, serta variabel user satisfaction berpengaruh secara signifikan terhadap continued usage intention. Namun variabel performance expectancy, sharia compliance, dan price value tidak berpengaruh terhadap user satisfaction. Penelitian ini diharapkan dapat menjadi preferensi pedoman yang berlaku untuk menerapkan dan merancang mobile banking secara efektif., The existence of digital services or one of them is mobile banking is the right solution to face competition in the banking industry. With the many advantages of mobile banking, Bank Muamalat Indonesia also adopts the benefits of the application to improve the quality performance of Bank Muamalat Indonesia. However, the survey report shows that the performance of digital services at Bank Muamalat Indonesia is lower than other digital Islamic banking services. This study aims to analyze the factors that influence customer satisfaction with digital services and their effect on customer loyalty at Bank Muamalat Indonesia. Measurement of customer satisfaction uses the concept of UTAUT 2 (Unified Theory of Acceptance and Use of Technology). The method used in this research is SEM-PLS. The results of the SEM-PLS analysis show that the variables of effort expectancy, social influence, facilitating conditions, and habit each have a significant effect on user satisfaction, and the variable user satisfaction has a significant effect on continued usage intention. However, the performance expectancy, sharia compliance, and price value variables have no effect on user satisfaction. This research is expected to be a guideline preference that applies to implementing and designing mobile banking effectively.

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
