Abstract

Di kota Surabaya terdapat perkumpulan orang Hakka yang sangat bersejarah dan dibangun pada tahun 1820 yaitu perkumpulan Hwie Tiauw Ka. Dalam masa perkembangannya selama hampir 200 tahun, perkumpulan ini sudah mengalami berbagai tantangan dan halangan, salah satunya yang dirasakan sekarang adalah sebagian besar dari pengurus perkumpulan ini adalah senior-senior yang sudah sepuh, sehingga yang sangat dibutuhkan sekarang adalah regenerasi, merekrut para pemuda untuk meneruskan perkumpulan ini. Banyak hal yang sudah dilakukan contohnya, membuka les bahasa Hakka, melaksanakan berbagai bentuk kegiatan, bahkan juga membentuk kelompok muda-mudi Hakka, dengan tujuan supaya semakin banyak generasi muda yang tertarik untuk mempertahankan eksistensi perkumpulan Hwie Tiauw Ka. Penulis menggunakan teknik penelitian kualitatif dan mewawancarai pemuda-pemudi Hakka yang pernah mengikuti kegiatan perkumpulan Hwie Tiauw Ka. Melalui penelitian ini dapat diketahui bahwa para informan merasa eksistensi perkumpulan ini harus dipertahankan, karena perkumpulan ini dapat membantu dalam mewariskan dan melestarikan budaya Hakka. Selain itu para informan juga menyampaikan ide mereka tentang cara-cara menarik generasi muda untuk ikut membantu mempertahankan perkumpulan Hwie Tiauw Ka.

Abstract

Perkembangan ilmu dan teknologi komputer telah mempengaruhi segala aspek kehidupan manusia seperti di bidang pendidikan. Informasi dan data dapat dengan mudah dan cepat untuk dikirim ke konsumen melalui jaringan komputer. Hal ini tentu saja menimbulkan risiko jika informasi dan data yang dikirim bisa diakses oleh pihak yang tidak berhak sehingga mengakibatkan kebocoran data. Masalah keamanan merupakan salah satu aspek terpenting dari sebuah sistem informasi. Apabila mengganggu performansi sistem, masalah keamanan  sering tidak dipedulikan, bahkan ditiadakan. Dalam kriptografi terdapat dua konsep utama yaitu enkripsi dan dekripsi. Enkripsi adalah proses dimana informasi yang dikirim diubah menjadi bentuk yang tidak dikenali sebagai informasi awalnya dengan menggunakan algoritma tertentu. Dekripsi adalah kebalikan dari enkripsi yaitu mengubah kembali bentuk yang tersamar menjadi informasi awal. Dewasa ini telah banyak beredar  program proteksi/enkripsi data baik yang bersifat freeware, shareware, ataupun komersial. Pada umumnya, program tersebut menyediakan beragam metode kriptografi sehingga kita dapat dipilih metode yang paling aman menurut kita. Salah satu metode kriptografi adalah Kriptografi kunci publik yang dilakukan dengan cara menggabungkan secara kriptografi dua buah kunci yang saling berhubungan, yaitu pasangan kunci publik dan kunci privat. Kedua kunci tersebut dibuat pada waktu yang bersamaan dan saling terhubung secara matematis. Salah satu jenis kriptografi adalah kriptografi simetris dimana kunci yang digunakan untuk enkripsi dan dekripsi adalah sama. Jika dibandingkan dengan kriptografi kunci publik, kriptografi simetris sangat cepat sehingga sangat cocok digunakan untuk melakukan enkripsi data yang sangat besar. Banyak yang menggabungkan algoritma kunci publik dengan simetris untuk memperoleh keunggulan dari masing-masing metode kriptografi. Dalam makalah ini, penulis akan membahas lebih lanjut tentang sistem keamanan data dengan metode kunci publik.

Abstract

This research is based on the background of increasing hospitality services business competition, and to win this competition, is influenced by three factors, one of which is the selling price. The selling price is the sum between Cost or Cost of Goods Sold (HPP) with a Mark up or percentage of the desired profit. Cost of Goods Sold is all costs incurred to obtain goods sold or the cost of goods sold. When an entity can manage costs incurred effectively and efficiently, it can increase the number of visitors and increase company profits. The research method used is descriptive qualitative method, which is to explain the phenomenon or event being studied. The results of the study are known that  the calculation of the cost of the room by using ABC has a difference with the basic price determined by the management of XYZ Hotel. This difference is caused by differences in the overhead costs for each type of room contained in XYZ Hotels. In calculations determined by the management of XYZ Hotel, overhead costs are not included in the calculation of the cost of the room and are only charged to one type of cost driver.Keywords : Cost of Good Solds, Activity Based Costing, Hotel, Activity, Cost Driver.
