Abstract

Internet banking atau mobile banking adalah salah satu bentuk aplikasi yang berbasis internet yang dapat digunakan sebagai pintu gerbang menuju dunia perbankan masa depan. Dalam memberikan layanan, pihak bank tidak ingin mengecewakan nasabahnya karena aplikasi internet banking yang sulit digunakan sehingga mengakibatkan nasabah gagal dalam mencari informasi atau gagal melakukan aktivitas perbankan. Melihat pentingnya usabilitas sebuah aplikasi, maka dilakukan penelitian terhadap aplikasi Mandiri Online untuk mengetahui kelayakan dari aplikasi tersebut, mengidentifikasi permasalahan usabilitas, serta menyusun rekomendasi perbaikan. Aplikasi tersebut diuji menggunakan System Usability Scale (SUS) dan pendekatan heuristic evaluation dengan responden sebanyak 40 orang untuk metode SUS dan 5 evaluator dengan kriteria single-expert untuk pendekatan heuristic evaluation. Hasil pengujian aplikasi Mandiri Online dengan instrumen SUS adalah sebesar 79,6 yang berarti aplikasi Mandiri Online dinyatakan dapat diterima (acceptable), termasuk dalam grade B dengan rating good. Dari penelitian ini juga diketahui bahwa terdapat beberapa permasalahan usabilitas mayor yang harus segera diperbaiki dan harus diberi prioritas tinggi. Dalam menyelesaikan permasalahan tersebut membutuhkan beberapa usaha, seperti  menambahkan fitur search untuk mencari nama bank, membuat pengelompokkan instansi pada menu multipayment, membuat atau menambahkan panduan penggunaan atau flowchart penggunaan Mandiri Online, dan menambahkan fitur help pada Mandiri Online. Abstract[Title: Usability Analysis of Mandiri Online Apllication] Internet banking or mobile banking is a form of internet-based application that can be used as a gateway to the future of banking. In providing services, banks won’t to let down their customers because of internet banking applications are difficult to use, resulting in failure to find information or fail to conduct banking activities. Seeing the importance of application usability, a study of Mandiri Online application was conducted to find out the appropriatness of the application, identify usability issues, and construct recommendations for application improvement. This application was tested using the System Usability Scale (SUS) and heuristic evaluation approach with 40 respondents for the SUS and 5 evaluators with single-expert criteria for the heuristic evaluation. The result of testing the Mandiri Online application with the SUS instrument amounted to 79,6 which means this application was declared acceptable, included in grade B, and with a good rating. From this study it is also known that there are some major usability problems that must be corrected immediately and must be given high priority. In solving these problems requires several efforts, such as adding search feature to search the bank’s name, creating agency groups on multipayment menu, creating or adding usage guidelines or flowcharts for using Mandiri Online, and adding help feature to Mandiri Online.Keywords: Heuristic Evaluation; System Usability Scale; Usability

Abstract

The Ngudi Rejeki Women Farmers Group (KWT) in Gunungkidul Regency has developed a mocaf (Modified Cassava Flour) production business as a solution to increase the added value of local cassava, which has a low selling price. However, limitations in production capacity and business strategy hinder the potential development of the business. This study aims to analyze the business model of KWT Ngudi Rejeki using the Business Model Canvas (BMC) framework that includes nine main elements of the business, and provide strategic recommendations based on the analysis results. The research approach is descriptive qualitative with a case study method, where data is collected through in-depth interviews, direct observation, and document review. The results of the analysis show that although KWT has a good business foundation, there are several areas that require improvement, such as product diversification, adoption of modern technology, expansion of distribution channels, and development of strategic partnerships. The contribution of this research lies in the formulation of a more innovative and measurable business strategy, which is expected to strengthen the competitiveness and business sustainability of KWT Ngudi Rejeki in national and international markets. In addition, this research provides policy recommendations in the form of government support and related institutions in terms of technology training, business assistance, and promotion of local products.

Abstract

This research aims to analyze and describe the development of tourism in Maluku Province, Indonesia on Instagram. The data used in this study are hashtags from several excellent tourist attractions or tourist priorities set by the maluku province tourism office. The data is then processed using social network analysis to find the level of importance and connectedness of tourism hashtags with other hashtags used in image captions on Instagram posts. The results showed that there are nine hashtags that have an important role in the network because they have high values in the measurement of degree centrality, betweenness centrality, closeness centrality, and eigenvector centrality. The hashtags are #maluku, #ambon, #natsepa, #pulauosi, #pulaubair, #beach, #repost, #indonesia, and #namalatu. Two of nine hashtags have a high betweenness centrality value, namely #natsepa that represent natsepa beach tourism and #namalatu that represents namalatu beach tourism. Both of these tours have a high value betweenness centrality with a different form of hashtags, namely #natsepa.id and #namalatu02. This research conducted using social network analysis degree measurements such as degree, betweeness, closeness, and eigenvector to analyze insight of tourism topics in Instagram. The result of this research can give insights to the tourism actors, especially in Maluku Province, of how the hashtags are connected and related. The relation of the hashtags can be used as social media marketing strategy.

Abstract

PT XYZ is a manufacturing company engaged in the production of sugar and its by-products. Currently, the determination of the amount of production at PT XYZ has not been adjusted to meet customer demand, which may continue to decrease or increase for each period. If there is a condition that the amount of production is greater than demand, it will increase the cost of storage due to accumulation. Meanwhile, if the amount of production is smaller than demand, there will be an out-of-stock condition that can reduce consumer confidence. These problems can be solved by forecasting Tambora Sugar demand at PT XYZ to meet consumer demand using the forecasting method (forecasting) with the help of WinQsb software with input, namely sugar demand data from 2021 PT SMS. The request data will later be analyzed from the request using a scatter diagram. Furthermore, after the pattern is known, the appropriate forecasting method will be determined and inputted into the WinQsb software. Based on the calculation results, it is known that the demand pattern from last year tends to trend down so the chosen method is the Double Exponential Smoothing (DES), Single Exponential Smoothing (SES), and Linear Regression (LR) method, with the best method being Linear Regression which produces the smallest error. The output is in the form of a Master Production Schedule (MPS), namely in the 13th to 18th periods, respectively 2142; 1757; 1373; 989; 604; 220 sacks.

Abstract

Penelitian ini bertujuan untuk menganalisis perilaku konsumen produk Mocaf melalui segmentasi berbasis data menggunakan metode K-Means Clustering. Masalah utama yang dihadapi adalah kurangnya pemahaman mendalam mengenai pola konsumsi, preferensi, dan karakteristik demografis konsumen Mocaf, yang menjadi kendala dalam pengembangan strategi pemasaran yang efektif. Untuk mengatasi masalah ini, data dikumpulkan melalui kuesioner online yang mencakup informasi terkait usia, pekerjaan, lokasi tempat tinggal, dan preferensi produk dari 195 responden. Analisis data dilakukan dengan menentukan jumlah klaster optimal menggunakan metode Elbow, yang menghasilkan empat klaster utama. Setiap klaster memiliki karakteristik unik berdasarkan demografi, lokasi, dan preferensi terhadap produk Mocaf tertentu. Hasil penelitian ini memberikan wawasan strategis yang dapat digunakan untuk menyusun strategi pemasaran yang lebih terarah, seperti pemanfaatan media digital, kolaborasi dengan komunitas lokal, dan promosi berbasis produk unggulan sesuai segmen pasar. Selain itu, penelitian ini berkontribusi pada pengembangan strategi pemasaran berbasis data yang tidak hanya relevan dengan kebutuhan konsumen tetapi juga mendukung penguatan produk lokal di pasar yang lebih luas.
