The competition in the business world, including banking, is getting tighter. For that, every bank must think of the right strategy to win the competition. One important strategy for winning competition is to prioritize customer satisfaction which is determined by the quality of banking services offered to customers. This study aims to analyze and process proposals for improvement in service quality in terms of using internet banking services based on the Quality Function Deployment (QFD) method through the preparation of the House of Quality (HoQ). The study was conducted on 120 internet banking users at the BRI Balikpapan Branch Office in East Kalimantan. From the results of the analysis, it is known that there are 11 indicators of bank internet banking service quality that must be improved as the first priority and 4 indicators as the second priority. Based on the results of data processing using QFD through the preparation of HoQ, it is known that there are 6 priority improvements that must be made by the bank. From the results of this study, it can be seen strategies for improving internet banking services to improve the quality of internet banking services at the BRI Balikpapan Branch Office, namely the added of new online chat features, perform server maintenance, carry out enrolment of new internet banking features, evaluate the process speed of each application feature, conduct regular website feature evaluations every quarter and perform network repair.

This study aims to analyze the effect of knowledge management, green commitment and employee green behavior on organizational sustainability in banking institutions. The research method used is a qualitative method with the object of employee research at banking institutions in Indonesia. This study used a sample size of 150 people. Data analysis used SEM (structural equation model) with PLS (partial least square) software. The results of the study provide information about the influence of knowledge management, green commitment and green employee behavior on organizational sustainability in banking institutions.

The purposes of this research are to identify marketing strategies using exposure in the online business world, explain the role and understanding of Exposure in the online marketing business, and explain the marketing system in social media influencers. The method used in this research is descriptive method. The results of this study is that exposure could be one of the best way to promote the product. This study discusses about exposure, influencers' social media, barter exposure, barter exposure system in influencers' social media, and the benefits of doing barter exposure in marketing.

Komunikasi data berkecepatan tinggi memerlukan teknik modulasi yang dapat mengatasi terjadinya ISI (Inter-Symbol Interference) dan respons frekuensi kanal yang tidak rata. OFDM (Orthogonal Frequency Division Multiplexing) merupakan teknik transmisi multicarrier dengan periode simbol relatif lebih lebar dibandingkan nilai delay spread kanal. Dengan subcarrier spektral yang lebih sempit dari lebar-pita frekuensi koheren, OFDM diharapkan memiliki ketahanan terhadap gangguan kanal yang tidak rata. FEC (Forward Error Correcting) masih dibutuhkan untuk meminimumkan efek kesalahan akibat dari beberapa subcarrier yang mengalami fading lebih kuat dibandingkan lainnya. FEC dengan teknik pengkodean konvolusional dan interleaver banyak dipakai pada standar OFDM seperti Wireless LAN 802.11a dan Direct Video Broadcasting. Hasil simulasi menunjukkan pengkodean konvolusional [133 171] memberikan nilai coding gain maksimal 6 dB untuk modulasi subcarrier QPSK dan 7 dB untuk 16-QAM. Pada kanal radio mobile dengan frekuensi doppler 0, 9, 56 dan 130 Hz, diperoleh coding gain 7 dB. Penggunaan matriks interleaver 32?18 (IS�95) bekerja kurang optimal dengan perbaikan daya kurang dari 1dB. Ketika frekuensi doppler 130 Hz, matriks interleaver 100?96 mampu memperbaiki kinerja sistem secara siginifikan, BER di sekitar 10-6 dicapai pada SNR = 16 dB.Kata kunci: OFDM, interleaver, delay spread, frekuensi doppler, coding gain, IFFT-FFT

In current banking digitalization era, bank could meet this challenge by launching a payment technology using QR code scan, that use devices owned by their customer by scanning QR code attached to the merchant. Customer satisfaction should be prioritized which is determined by the quality of goods or services. E-ServQual intended to examine transaction accuracy, speed to solve problems online, required information easily available, and ease of accessing QR Pay. This study aimed to analyze bank customer satisfaction level in using QR Pay service based on ServQual method integrated with Fuzzy logic. This research also identified service variables prioritized by customers by using Importance Performance Analysis (IPA). This study conducted on 69 customers of Bank QR Pay service in one Branch Office of State-Owned Enterprises bank in Balikpapan, East Kalimantan. Study result indicated that the need of QR Pay strategy improvement service that comprised of transaction accuracy, speed to solve problems online, required information easily available and ease of accessing the QR Pay.
