"Tingkat loyalitas konsumen sudah banyak diprediksi dengan berbagai atribut dari framework kepuasan pelanggan, tetapi output yang dihasilkan tidak konsisten. Konsep yang sedang berkembang saat ini yang dianggap sebagai predictor yang baik untuk loyalitas adalah customer experience. Ada delapan faktor pembentuk B2C customer experience menurut Lemke et al. (2006), yaitu accessibility, competence, customer recognition, helpfulness, personalization, problem solving, promise fulfillment, dan value for time. Dari penelitian terhadap responden yang dalam enam bulan terakhir berinteraksi dengan Hoka Hoka Bento didapatkan hasil bahwa problem solving, promise fulfillment, serta value for time merupakan tiga faktor yang paling berkorelasi dengan customer experience dan accessibility merupakan faktor dengan korelasi terendah. Penelitian ini juga mendapatkan hubungan yang kuat antara customer experience dengan loyalitas.

Many researchers have predicted consumer loyalty based on attributes from customer satisfaction framework, but many found inconsistent results. Customer experience is a growing concept which is considered as a good predictor for loyalty. There are eight factors which contribute to customer experience based on research by Lemke et al. (2006); accessibility, competence, customer recognition, helpfulness, personalization, problem solving, promise fulfillment, and value for time. From research concerning to respondents which in the last six months interacting with Hoka Hoka Bento, results show that problem solving, promise fulfillment, and value for time are three factors with the highest correlation with customer experience and accessibility is the lowest. This research also finds strong correlation between customer experience and loyalty."

"Aluminum, as a conductor material, has long been used for high-voltage overhead transmission lines due to its economic value and high electrical conductivity. By adding Al2O3np and alloying elements such as zirconium (Zr), cerium (Ce), and magnesium (Mg), aluminum’s strength and performance could be improved without compromising too much of its electrical conductivity. The focus of this research was to investigate the mechanical, electrical properties, and microstructure of Al-0.12%Zr-0.15%Ce-5%Mg, reinforced with different volume fractions (from 0.5 to 1.5%) of Al2O3 nano particles, using the stir casting method. The tensile strength of the composite was improved by up to 1.2 vf-% in alumina, and decreased with further addition due to clustering and pores, while elongation was reduced with when increasing the reinforcement. It was found that the electrical conductivity of the composite generally decreased with the addition of reinforcement. The microstructure observations showed that the composites yielded finer grains and more pores than the unreinforced alloy, with 1.2vf-% of reinforcement having the finest grain. The electrical conductivity of the composite was 44% IACS, which is still lower than that of the unreinforced alloy."

"Kami melakukan perhitungan konduktivitas optis pada layered (perovskite) Pr0.5Ca1.5MnO4 untuk mengidentifikasi fenomena charge-ordering. Pemodelan melibatkan orbital Mn dan O yang berada pada bidang MnO2 dari layered Pr0.5Ca1.5MnO4. Interaksi yang diperhitungkan dalam pemodelan yaitu interaksi Coulomb inter-orbital dan intra-orbital, distorsi Jahn-Teller dan exchange interaction dengan menerapkan beberapa asumsi. Perhitungan dilakukan menggunakan Dynamical Mean Field Theory untuk mencapai self-consistency. Hasil perhitungan menunjukkan profile yang mendekati hasil eksperimen dengan puncak charge-ordering berada di bawah 1 eV dan puncak charge-transfer pada 3-3.7 eV. Di bawah temperatur TCO/OO (~325 K), puncak charge-ordering mengalami blue shift seiring dengan penurunan temperatur.

We calculate the optical conductivity of layered (perovskite) Pr0.5Ca1.5MnO4 to capture charge-ordering phenomena. The calculations are based on a model which considers Mn and O orbitals within the MnO2 plane of layered Pr0.5Ca1.5MnO4. Interaction terms included in the model with some assumptions are the inter-orbital and intra-orbital Coulomb repulsions, the static Jahn-Teller distortion and the exchange interaction. We calculate within Dynamical Mean Field Theory to achieve self-consistency. The result shows a profile similar to recent experimental data, where the charge-ordering peak appears below 1 eV and charge-transfer peak at 3-3.7 eV. For temperature lower than TCO/OO (~325 K), the charge-ordering peak undergoes a blue shift as the temperature is decreased."

Background: Colorectal cancer is the third largest malignancy in the world with the highest incidence and cause of death. The role of early detection of colorectal cancer with direct visualization and certain markers has been proven to reduce incidence and death rates, however this program has a low participation rate. Non-invasive methods of stool-based examination have been used and developed. The combination of CEA mRNA, COX-2 mRNA and FIT in feces is expected to be a non-invasive early detection method with good sensitivity and specificity as a diagnostic marker for colorectal cancer.

"Aluminium sebagai bahan konduktor sangatlah luas pengaplikasiannya. Salah satunya adalah untuk kebutuhan kabel transmisi tinggi. Semaikin hari kriteria yang harus dimiliki kabel transmisi ini semakin tinggi, mengingat kebutuhan listrik yang semakin meningkat. Didalam penelitian ini akan dibahas mengenai pembuatan serta pengkarakterisasian material komposit AlZrCe/Al2O3 nano partikel dengan metode pengecoran aduk untuk keperluan kabel transmisi.Di dalam matriks, zirkonium akan menambah ketahanan panas sedangkan cerium akan menjaga konduktivitas listrik agar tidak turun dan diharapakan penambahan partikel Al2O3 akan meningkatkan kekuatan tarik dari komposit ini. Magnesium sebesar 5 wt% ditambahkan sebagai unsur peningkat kemampubasahan antara matriks dan penguat.Didapatkan bahwa penambahan Al2O3 akan meningkatkan kekuatan tarik, menurunkan konduktivitas listrik dan menurunkan koefisien muai panas komposit ini. Titik optimal untuk mendapatkan sifat mekanik listrik dan panas yang paling baik didapatkan pada fraksi volume 1,2% Al2O3. Daerah antarmuka yang didapatkan oleh seluruh sampel pengujian tidaklah baik, sehingga data yang dihasilkan belum bisa optimal dan sesuai dengan harapan.

The requirements that must be owned of high-voltage overhead transmission lines are getting higher these days, because the electric needs are increasing. In this research will be investigated about fabrication and characterization AlZrCe/Al2O3(np) using stir casting process for overhead cable transmission.

In the matrix, zirconium will be increase heat resistance, cerium will keep the value of electrical conductivity in order not to decrease and the addition of Al2O3 particles is expected to increase the tensile strength of the composite. Magnesium 5 wt% was adding as wettability agent.

The results showed that the addition of Al2O3 will increase the tensile strength, decrease electrical conductivity and decrease coefficient thermal expansion of this composite. The optimal value for get the best of mechanical, electrical and thermal properties is obtained at 1.2% Al2O3 volume fraction. Interface areas obtained by the entire sample testing is not good, so the resulting data can not be optimal and appropriate expectations."

The research is focusing on the influence of rare earth cerium Ce element on intermetallic phase that is formed on the solidification process, where cerium Ce is added on 0.1 0.3 and 0.5 wt level on Al 5Zn 0.5Si alloy as microstructure rsquo s grain refiner and precipitates rsquo refiner which will be formed on the solidification process. The more cerium Ce added gradually, the better sacrificial anode efficiency to be exposed to corrosion. The addition of more cerium Ce will make the grain size smaller from 108.42, 97.14, 94.55 mm. The added cerium Ce will be affected on the Icorr from 0.8x10 5, 1.3x10 5, 2.9x10 5 Volt, as sacrificial anode efficiency. The intermetallic phase formed can be seen in the graph generated from the DSC Differential Scanning Calorimetry testing, which describes the presence of AlCeSi2 Al Si and Al2Zn2Ce phases that may affect the effectiveness of sacrificial anodes."
