Abstract

The information system for rapid assessment of the BPBD of DKI Jakarta Province was built so that the fire disaster data processing system at the BPBD of DKI Jakarta Province could run precisely, effectively and efficiently. The case approach at BPBD DKI Jakarta Province uses a descriptive method, which is a method with the aim of making a systematic, factual, and accurate description of the facts and characteristics of a particular research object. In the first stage, the writer collects the data and materials needed first, and in the next stage the writer processes and discusses to arrive at a conclusion. The fire rapid assessment information system built by the author uses the Java programming language and Mysql database which can provide previous convenience in terms of processing fire data quickly and precisely compared to systems that still use manual systems, providing automatic calculations that make it easier to meet the basic needs of fire victims, and also able to generate reports of fire events, disaster reports, refugee data, calculation of basic needs and handling of fire data. Before the new system is implemented, it is recommended that the Emergency and Logistics Division be given a good explanation first, regarding the work process that will be implemented so that no incident occurs. And it is necessary to conduct training on the use of the system for the distribution section of this system so that they can know and understand how the new system works.

Abstract

Pandemi Covid-19 membuat perilaku masyarakat menjadi berubah, tidak terkecuali dengan perilaku konsumen. Terbatasnya ruang gerak masyarakat untuk memenuhi kebutuhan sehari-hari aklibat adanya Pemberlakuan Pembatasan Kegiatan Masyarakat (PPKM) membuat masyarakat lebih memilih untuk berbelanja kebutuhan harian melalui e-commerce. Fenomena ini tentu saja membuat bisnis e-commerce semakin melesat. Data Global Web Index (GWI) pada kuartal ke-3 Tahun 2020 menyebutkan bahwa sebanyak 78.2 % pengguna internet dengan usia 16-64 tahun menggunakan aplikasi belanja online pada HANDPHONE dan tablet mereka untuk bertransaksi di e-commerce. Sedangkan jumlah pengunjung pada situs web-nya hanya sebanyak 22% saja. Data tersebut menunjukkan bahwa konsumen lebih memilih berbelanja menggunakan aplikasi belanja online dibandingkan web. Salah satu e-commerce yang paling banyak dikunjungi oleh konsumen Indonesia adalah Shopee. Hal ini berdasarkan data Similar Web pada September 2021 yang menyebutkan bahwa Shopee menjadi aplikasi e-commerce nomor satu yang paling banyak dikunjungi di Indonesia, mengalahkan Tokopedia dan Lazada. Laporan iPrice di Q4-2020 juga menyatakan bahwa Shopee menjadi platform marketplace dengan pengguna aktif terbanyak di Indonesia dengan jumlah pengunjung bulanan 129,320,800. Selain itu, Shopee juga berhasil mendapatkan 26,92 juta Unique Daily Actives Users (DAU) atau pengguna aplikasi aktif harian yang mengakses melalui Android di Indonesia pada Agustus 2021. Melihat capaian-capaian Shopee tersebut, dapat memberikan kesempatan bagi penjual untuk menjangkau banyak pembeli dan meraih keuntungan. Shopee juga memberikan kemudahan bagi penjual untuk membuka toko serta tanpa biaya atau gratis. Selain itu, Shopee juga memberikan banyak promo, salah satunya ‘gratis ongkos kirim’. Promo ini tentunya sangat berdampak baik bagi penjual asalkan toko tersebut sudah ikut mendaftar ‘promo gratis ongkir’. Masih banyak keunggulan Shopee lainnya bagi para penjual. Untuk itu, tak ada salahnya jika kita mulai membuka toko di Shopee agar kita bisa santai menjadi bos di rumah tanpa perlu repot-repot berjualan di lapak yang mahal.

Abstract

Abstrak - Dalam dunia sekarang ini, kemajuan teknologi di bidang komputer dan telekomunikasi berkembang sangat pesat. Lalu lintas pengiriman data dan informasi yang semakin global, serta konsep open system dari suatu jaringan  memudahkan seseorang untuk masuk ke dalam jaringan tersebut. Hal tersebut dapat membuat proses pengiriman data menjadi tidak aman dan dapat saja dimanfaatkan oleh pihak lain yang tidak bertanggung jawab, yang mengambil informasi atau data yang dikirimkan tersebut di tengah perjalanan. Maka dibutuhkan suatu sistem keamanan yang dapat menjaga kerahasiaan suatu data, sehingga data tersebut dapat dikirimkan dengan aman. Salah satu solusi untuk menjaga keamanan dan kerahasiaan pada proses pengiriman data dengan menggunakan teknik kriptografi. Dalam makalah ini penulis merealisasikan suatu perangkat lunak enkripsi dan dekripsi file teks dengan menggunakan algoritma kriptografi yaitu simetri. Di samping itu untuk meningkatkan keamanan pada perangkat lunak disertakan juga proses validasi dan proses digital signature,sehingga perangkat lunak dapat mendeteksi adanya perubahan data atau informasi yang dikirimkan serta menjamin keaslian pengirim informasi.Kata Kunci: Simetris, Kriptografi, PHP Abstract - In today's world, technological advances in the fields of computers and telecommunications are growing very rapidly. The increasingly global traffic of data and information delivery, as well as the open system concept of a network, make it easy for someone to enter the network. This can make the data delivery process unsafe and can be exploited by irresponsible parties, who take the information or data sent in the middle of the journey. So a security system is needed that can maintain the confidentiality of data, so that the data can be sent safely. One solution to maintain security and confidentiality in the data delivery process is to use cryptographic techniques. In this paper, the author realizes a text file encryption and decryption software using a cryptographic algorithm, namely symmetry. In addition, to increase security in the software, a validation process and a digital signature process are also included, so that the software can detect changes in data or information sent and guarantee the authenticity of the sender of the information.Keywords: Symmetric, Cryptography, PHP
