: Dalam mengirim pesan perlu diperhatikan mengenai keamanan isi pesan tersebut, maka dari itu, di butuhkan sebuah metode untuk mengamankan informasi dengan aman. Algoritma kriptografi merupakan sebuah metode yang bukan hanya melindungi tapi juga mengubah informasi yang ada sehingga meskipun informasi tersebut diketahui pihak yang tidak bertanggung jawab informasi ini belum tentu bisa dimengeri oleh pihak yang tidak bertanggung jawab tersebut. Pada penelitian ini menggunakan metode Agile yang bertujuan mempermudah pemahaman dalam penerapan algoritma kriptografi caesar cipher asimetris. Dalam Melakukan pengujian algoritma kriptografi asimetris, penelitian ini menggunakan bahasa pemrograman python untuk melakukan implementasian. Hasil akhir dari penelitian ini adalah kriptografi asimetris bisa melakukan enkripsi dan dekripsi sama dengan kriptografi caesar cipher simetris meskipun algoritmanya berubah yang awalnya simetris menjadi asimetris.

This study aims to determine and analyze network performance with quality of service parameters in realizing good and optimal network performance quality so that it can be adjusted between the efficiency of network needs and the effectiveness of user access at the Communication and Informatics Office of West Sumbawa Regency. The process of accumulating data is obtained by measuring the quality of service parameters using the quality of service method and measuring bandwidth load distribution with the load set at 30 Mbps. The quality of service method on the network, the influence between the variables of network performance quality on the internet connection, and the bandwidth capacity of each user are known. The study results from the quality of service analysis at the Communication and Informatics Service of West Sumbawa Regency entered the excellent category with an average throughput value ranging from 10,320-1,026,454 kbps from the fourth index being in the excellent category. The average packet loss value of 0-1.5% of the third index is in a good category, with the highest value occurring on the fifth day, 1.5%. The average delay value ranges from 7-150 ms, with the highest delay value occurring on the first day due to the user's distance from the remote network access source and queues in dense packet transmission. The average jitter value of 1-12 ms from the third index is in a good category, and the maximum result of the bandwidth value set in size is 9,092,407 bps

Electronic-based government develops in harmony with advances in technology to improve public services. A common problem that often occurs is that many online public service sites do not pay attention to their use so not a few website users get confused, bored, or even lose their way because of an inappropriate appearance. In addition, many online administration sites nev-er evaluate the usability of the website. The focus of this study aims to empirically test the usa-bility of the ATR/BPN Sumbawa website based on the level of severity with the heuristic evalu-ation principle. This research is a quantitative study using a questionnaire with a total of 30 re-spondents, 10 people consisting of active users including ATR/BPN Sumbawa employees, and 20 people who are community users of the website. This research is based on the assessment of ten heuristic evaluation principles with a usability scale system. This research begins with data col-lection, analysis, or testing as well as website assessment and recommendations. The results can be concluded about the evaluation of website usability according to the ten heuristic principles and according to respondents from 43 questionnaire statements as a whole the ATR/BPN Sum-bawa website has fulfilled the 10 heuristic characteristics. Each value in each variable gives an average value agreeing with the indicators in the heuristic principle.

Climate conditions affect the water balance in an area. Bange Tango Regency is an area that is dominant with agricultural land, so it requires good irrigation to develop the potential of agricultural land, however meeting agricultural irrigation water needs is still difficult, especially entering the peak dry season in early August to mid-late October with average temperatures. -The highest average is above 32°C, even in October, with an average lowest temperature of 33°C with a low water vapor concentration even though it is influenced by the southeast wind which blows from the Australian Continent towards the Asian Continent which passes through the Sumbawa Island area and its surroundings. . This research was carried out to detect new water sources apart from the use of surface water sources such as river dam water, lakes and shallow wells (dig wells) in the context of land extensification to increase the usability of agricultural land in the dry season. This research is experimental for the detection of groundwater potential using the Schlumberger configuration resistivity geoelectric method with two sounding point distances of 200 m. The research results show that the aquifer layer in this area is sandstone with a resistivity value of 26.15 Ωm and at a depth of 48.56 to a depth of 54.77 MBMT, while the estimated optimum pumping discharge is ± 1.00 liters/second.
