Abstract

Mutual funds are one of the promising investment media where the risk is directly proportional to the size of investment growth. With proper forecasting of NAV price movements will greatly help investors to make purchases and sales transactions, therefore the authors offer the use of two different forecasting methods namely Brown's method and Holt method in double exponential smoothing to get predictions of NAV price movements. The effectiveness of the use of the method will be measured from the value of Mean Average Percentage Error (MAPE). From the calculation results obtained by the data that the Holt method produces forecasting for 1809,657 with the best α value of 0.6 and MAPE of 0.644373568, while for the Holt method obtained forecasting value of 1810,924 with the α value and the best β value of 0.9 and 0.1 and the smaller MAPE value of 0.61604262 . Looking at the amount of MAPE generated, the Holt method has a smaller forecasting error rate when compared to Brown’s method.

Oleh karena itu penelitian ini bertujuan untuk membangun aplikasi Rekberkuy pada komunitas facebook menggunakan pemrograman API. Pengambilan data pada penelitian ini didapatkan melalui wawancara dan observasi pada anggota grup XYZ di Facebook. Pada tahap pengembangan perangkat lunak, digunakan pendekatan prototyping dengan beberapa tahapan dan dibuat dalam jangka waktu 5 bulan. Hasil dalam penelitian ini yaitu implementasi payment gateway midtrans pada aplikasi rekberkuy berjalan dengan baik. Dengan melakukan testing pada transaksi beberapa customer menggunakan rekberkuy membuktikan bahwa system payment gateway midtrans berintegrasi dengan baik oleh rekberkuy dan mendapatkan komentar positif dari pembeli maupun penjual yang melakukan transaksi pada grup XYZ di Facebook.

Abstract

Sistem rekomendasi saat ini sedang menjadi tren. Kebiasaan masyarakat yang saat ini lebih mengandalkan transaksi secara online dengan berbagai alasan pribadi. Sistem rekomendasi menawarkan cara yang lebih mudah dan cepat sehingga pengguna tidak perlu meluangkan waktu terlalu banyak untuk menemukan barang yang diinginkan. Persaingan antar pelaku bisnis pun berubah sehingga harus mengubah pendekatan agar bisa menjangkau calon pelanggan. Oleh karena itu dibutuhkan sebuah sistem yang dapat menunjang hal tersebut. Maka dalam penelitian ini, penulis membangun sistem rekomendasi produk menggunakan metode Content-Based Filtering dan Term Frequency Inverse Document Frequency (TF-IDF) dari model Information Retrieval (IR). Untuk memperoleh hasil yang efisien dan sesuai dengan kebutuhan solusi dalam meningkatkan Customer Relationship Management (CRM). Sistem rekomendasi dibangun dan diterapkan sebagai solusi agar dapat meningkatkan brand awareness pelanggan dan meminimalisir terjadinya gagal transaksi di karenakan kurang nya informasi yang dapat disampaikan secara langsung atau offline. Data yang digunakan terdiri dari 258 kode produk produk yang yang masing-masing memiliki delapan kategori dan 33 kata kunci pembentuk sesuai dengan product knowledge perusahaan. Hasil perhitungan TF-IDF menunjukkan nilai bobot 13,854 saat menampilkan rekomendasi produk terbaik pertama, dan memiliki keakuratan sebesar 96,5% dalam memberikan rekomendasi pena.

Abstract

This research was conducted in an attempt to identify and analyze the role and influence of two universally applicable theories in the life of an employee when working in a company. The research subjects are employees who work at the bank. The data collection model is carried out primarily using a questionnaire to explore their perceptions in creating and or maintaining a sense of loyalty in their workplace. To prove this, the researchers chose a bank that has been around for a long time, where there are 25 employees. We want to know whether Maslow and Herzberg's theory of motivation remains universally applicable in their work environment. This research is an associative study using the primary data base, this data from interviews and filling out questionnaires from the bank employees. Measurement of data using ordinal data with a Likert scale approach. From the results of filling out the questionnaire, the percentage results obtained that 71.4% of them tend to agree on the existence of their existence and fulfill their needs hierarchically. Through associative analysis, it can be obtained that the physiological results are 49.1% well fulfilled, sense of security is 47.4% fulfilled, social 43.8% is fulfilled, self-esteem 72.5% is fulfilled, and self actualization is 49.1% also fulfilled in the bank, this condition is enough to make their employees loyal in contributing energy, time and thoughts. Overall 93.7% of Maslow's hierarchical needs and Herzberg's maintenance are able to create a sense of employee loyalty to the workplace. The fulfillment of 72.5% hierarchical needs is dominated by the fulfillment of self-esteem, then in terms of maintenance theory, Herzberg is dominated by self-esteem and self-actualization
