Judul: Pengaruh Manajemen Kerelasian Pelanggan terhadap Loyalitas Nasabah PT Bank Muamalat Indonesia,Tbk Cabang Bogor
Abstrak: Loyalty is a customer commitment to constantly resubscribe and repurchase a product or service in the future. Every company wants the customer to have high loyalty toward their products, so does PT Bank Muamalat Indonesia (BMI), Tbk Branch Bogor. Loyalty appears because of customer satisfaction and good relationship between the customer and the company. Customer relationship management is needed to mantin a good relationship between the customer and the company. Customer relationship management in BMI is a company approaching to (1) customer identification (IDENT), (2) customer differentiation (DIFFER), (3) interaction to retain (INTER) and (4) technology development (TEKNO). The fourth independent variables, satisfaction (PUAS) and loyalty (LOYAL) as the dependent variables are variables that can not be measured 6 directly, so they are needed to take a few indicators as a measurement. Structural equation modeling is an approach that can be used to solve the problem. The structural equation modeling analysis is needed to see how customer relationship management and customer satisfaction influence customer loyalty. The result shows that the development of technology (TEKNO) is the factor that influences satisfaction (PUAS) and it is effected to customer loyalty (LOYAL).

Judul: Pengaruh Program Customer Relationship Management Terhadap Loyalitas Pelanggan (Study Kasus pada Bank Konvensional dan Bank Syariah di Kota Bogor)
Abstrak: The number of banks in Indonesia indicates the existence of competition in the banking industry. It can be seen from the percentage growth in customer deposits decreased. Percentage growth decline suggests that the two types of customers in the bank does not always save their money and tendency to move from one to another bank which ultimately lead to disloyal attitude. The existence of competition between the two types of banks in collecting deposits from customers, making the company tried to implement a marketing strategy that can affect customer loyalty to keep the money in the bank. One ofthose strategy is Customer Relationship Management. In This research will describe the influence of CRM programs on customer loyalty at conventional banks and Islamic banks in Bogor. The data processing using Structural Equation Model (SEM) method. Result of this Research indicate not all CRM programs have a significant effect on customer loyalty in conventional banks and Islamic banks. CRM programs that significantly affect customer loyalty in both types of banks i.e Continuity marketing programs and Partnering. The most dominant variable effect on customer loyalty in conventional banks is Continuity Marketing with a value of 0,65. While the Islamic banks are the most influential variables on customer loyalty is Partnering with a value of 0,45

Judul: Sintesis nanopartikel Cu2ZnSnS4 menggunakan teknik hidrotermal
Abstrak: Nanopartikel Cu2ZnSnS4 (CZTS) merupakan semikonduktor yang berpotensi sebagai fotokatalis untuk reaksi fotodegradasi zat pewarna. Semikonduktor ini memiliki sela pita yang jauh lebih kecil dibandingkan dengan semikonduktor TiO2, sehingga memungkinkan dapat berkerja hanya dengan paparan sinar matahari. Nanopartikel Cu2ZnSnS4 telah berhasil disintesis menggunakan teknik hidrotermal dengan suhu 200 oC selama 24 jam. Larutan Cu2ZnSnS4 dinetralkan menggunakan amonium hidroksida dan dialiri gas N2 sebelum proses hidrotermal. Hasil analisis mikroskop elektron pemayaran menunjukkan nanopartikel Cu2ZnSnS4 mengalami aglomerasi karena memiliki ukuran partikel yang besar. Hasil analisis difraktogram sinar-X menunjukkan bahwa Cu2ZnSnS4 yang dihasilkan memiliki struktur kesterit dengan senyawa fase sekunder yang terbentuk adalah CuS, ZnS, dan Cu2SnS3. Hasil uji fotodegradasi menunjukkan bahwa senyawa hasil sintesis memiliki kemampuan degradasi dibawah sinar matahari lebih baik dibandingkan dengan TiO2. Namun, pada paparan sinar UV, TiO2 mendegradasi biru metilena lebih baik daripada senyawa hasil sintesis. Kapasitas adsorbsi terhadap biru metilena sebesar 2.6780 mg/g menunjukkan bahwa senyawa hasil sintesis tidak mampu mengadsorpsi dengan baik, sehingga disimpulkan bahwa hilangnya biru metilena dari larutan disebabkan oleh fotodegradasi, bukan oleh adsorpsi
