Abstract

AbstrakSistem pembayaran elektronik (e-payment) dianggap sebagai tulang punggung e-commerce. Agar diterima secara luas metode pembayaran di seluruh dunia, sistem e-payment harus mengikuti protokol keamanan yang efisien yang menjamin keamanan yang tinggi untuk transaksi online. Secure Socket Layer (SSL) dan Secure Electronic Transaction (SET) merupakan dua protokol yang  banyak dibahas untuk mengamankan pembayaran kartu kredit online. Namun, SSL maupun SET telah gagal dalam implementasi pada pengguna akhir, sehingga munculah protokol Secure Electronic Payment (SEP) yang merupakan protokol e-payment yang aman dan efisien yang menawarkan lapisan tambahan perlindungan bagi cardholder dan merchant. Tujuan penulisan ini untuk menentukan protokol mana yang paling cocok untuk keamanan e-payment berdasarkan perbandingan pada end-user implementation requirements. Metode yang digunakan berupa studi literatur dengan melihat karya terkait yang membahas mengenai protokol SSL, SET, SEP yang selanjutnya akan dilakukan perbandingan. Hasil yang didapatkan dari perbandingan protokol keamanan e-payment SSL, SET, dan SEP berdasarkan faktor end-user implementation requirements (usability, flexibility, affordability, reliability, availability, interoperability) yaitu bahwa protokol SEP yang memenuhi syarat dan paling cocok untuk diterapkan dalam keamanan e-payment. Kata kunci: SSL, SET, SEP, security requirements of e-payment, end-user implementation requirements

Abstract

Shiau Printing is one of the businesses engaged in printing. This business often experiences production optimization problems, namely in terms of determining the maximum profit from the two types of products produced, namely banners and billboards. Constraints faced in the form of limited production resources, such as flexi materials. This problem can be solved by implementing linear programming using the simplex method and then testing it using the POM-QM application for Windows. Based on the results of calculations that have been made, a decision was drawn that the Shiau Printing could obtain a maximum income of IDR 15,000,000 -, / month.

Abstract

Usaha koperasi simpan pinjam ABC merupakan usaha yang bergerak di bidang jasa, dimana usaha ini sering mengalami masalah tentang perekapan data yaitu pencatatan transaksi karena human-error. Usaha ini dapat mengandalkan perangkat lunak atau aplikasi dalam kegiatan kerja sehari-hari agar lebih mudah dalam melakukan pengolahan atau manajemen data, baik data anggota, data pembayaran cicilan kredit hingga rekapan laporan usaha. Sehingga meminimalisir human-error serta meningkatkan kinerja koperasi simpan pinjam karena semua pencatatan transaksi dilakukan melalui aplikasi. Aplikasi ini dibangun menggunakan metode Research And Development (RD) serta perancangannya menggunakan Unified Modelling Language (UML). Hasilnya adalah aplikasi ini dapat mengelola data dengan baik, mulai dari data anggota, data setoran, data pengambilan, data peminjaman, data pembayaran cicilan serta dapat menampilkan rekapan laporan usaha sehingga data-data tersebut menjadi informasi yang bermanfaat. Pengujian yang dilakukan terhadap aplikasi ini menggunakan Black Box Testing, dimana setiap fungsi yang ada berjalan dengan baik (valid).

Abstract

Kawasan pesisir Kabupaten Kulon Progo terdiri dari empat kecamatan, yaitu kecamatan Galur, Panjatan, Wates, dan Temon. Kawasan pesisir ini rentan terhadap dampak negatif aktifitas manusia seperti penggunaan tanah atau pemanfaatannya yang sering tumpang tindih. Tujuan penelitian ini untuk menganalisis autokorelasi spasial terhadap pemanfaatan kawasan wilayah pesisir di Kabupaten Kulon Progo. Penelitian ini menggunakan salah satu pengujian autokorelasi spasial yaitu Local Indicators of Spatial Association (LISA) dengan indikator Local Moran's I, yang menghasilkan signifikansi secara statistik tinggi (hotspots), signifikansi secara statistik rendah (coldspots), dan pencilan (outlier). Hasil dari penelitian ini menunjukkan bahwa kecamatan yang termasuk kategori hotspots (H-H) diantaranya Temon dengan lima hotspots pada kawasan permukiman perdesaan, pertanian lahan kering, industri, sempadan pantai, dan suaka alam, Panjatan dengan tiga hotspots pada kawasan permukiman perkotaan, perdagangan, dan sempadan sungai, Galur dengan dua hotspots pada kawasan pertanian lahan basah dan perdagangan, dan Wates dengan satu hotspots pada kawasan industri.Kata kunci: kawasan pesisir, Kabupaten Kulon Progo, Local Indicators of Spatial Association, LISA, Local Moran's I.

Abstract

Oma Corry's business is a small-scale bread business in Sorong City, West Papua Province. One of the problems faced by Oma Corry Enterprises is the problem of calculating or determining the maximum profit gained every day from production activities. To calculate the benefits of Bread and Flour Bread and Babengka still use a calculator and write in books so it is less efficient. Whereas now the calculation of maximum profits must be completed quickly and precisely, so we need a system that can provide convenience in calculating profits. To achieve this goal, the simplex method is chosen for the manual calculation process and the POM-QM for Windows tool is used to speed up the calculation process. The result is a maximum profit of IDR 494,000 per day and a more efficient calculation process

Abstract

Sorong City is a part of West Papua Province, Indonesia. This city is one of the cities which have been affected by the Covid-19. This research attempts to provide a solution for the Sorong City Covid-19 Task Force’s need for forecasting number of potential Covid-19 positive patients in the coming months so that faster treatment could be made. Such need has emerged due to the absence of laboratories and the increasing number of positive Covid-19 patients in the city. The absence of laboratories in the city has made the task force to send samples of presumed Covid-19 patients to the laboratories in Makassar City in order to be examined and tested. This process has been time consuming and further reducing the task force’s already reduced performance effectiveness because of the social distancing policy applied in cities in Indonesia. The forecasting methods utilized in the research were the Moving Average and Exponential Smoothing. The methods were applied using POM-QM Software for Windows Version 5. The results of the Exponential Smoothing method are better than the results of the Moving Average method in forecasting the number of possible Covid-19 patients in July. For August and September forecasts, the results of the Moving Average method are better than the results of the Exponential Smoothing method. The results from both methods could be used as reference by the Sorong City Covid-19 Task Force in making decision and establishing policy.
