Abstract. Currently the level of data security becoming a major factor in data transfer. As we know every process of sending data through any medium the risk of that data gets hacked will still be there. Some techniques for securing data such as steganography and cryptography also often used as a solution for securing data. But it does not last long because it has been fou out the weaknesses of the algorithm so that the security be assured. So, in need of variety of new algorithms to be able to protect the data so that data security can be guaranteed. In this study tries to combine two visual algorithms that steganography and cryptography. Where in these experiments will try to secure two pieces of data type that is the type of image data and text data where both the data is regarded as a message so to obtain the correct information receiver should get that two types of data.
In internet, an ad is something that able to be avoided when opening a web page. At this time many internet based businesses rely on advertising for their income. However, users are dissatisfied with the presence of ads on websites they visit, since the size of the ad data is often proportional to the actual content ads. This impacts not only on loading web pages and may lead to a file that may potentially be a carrier of the virus and may damage the operating system of the visitor. A system that can overcome the annoying ads will be needed by the user for the convenience of users in using the internet media. To overcome this will be built a system using the pi-hole and Ubuntu operating system
The immune system of children are weaker than adults. They are susceptible to diseases. One of the diseases that often affects them is respiratory disease. Expert systems can be used to determine early diagnosis of it. Certainty Factor allows the user to measure the certainty’s degree of the diagnosis. It is also affecting the level of trust. It is easy for users to make decisions in determining the healing step. Symptoms of the disease are analysed and managed into the knowledge base of the expert system. The result of disease diagnosis is appeared in the form of disease data. The result data are accompanied by certainty value or percentage of confidence that obtained by certainty factor method applied.
Kursus merupakan salah satu jenis program pendidikan nonformal yang diselenggarakan secara terstruktur yang bertujuan untuk memberikan pengetahuan serta keterampilan kepada masyarakat agar masyarakat mampu meningkatkan keterampilan sehingga dapat memperbaiki taraf hidupnya. Kursus menjahit adalah suatu bentuk pemberian keterampilan menjahit kepada masyarakat melalui sebuah proses pembelajaran yang dilaksanakan secara terstruktur. Tujuan kursus menjahit adalah agar masyarakat mampu memiliki pengetahuan serta keterampilan menjahit sehingga dapat meningkatkan taraf hidupnya dan dapat mengembangkan bakat serta potensi yang dimiliki. Lembaga kursus jahit LKP Zere Amin merupakan lembaga kursus menjahit yang sebelumnya masih menggunakan metode manual dalam mempromosikan hasil desain karyanya. Akan tetapi, sekarang sudah waktunya lembaga ini harus lebih dikembangkan lagi dengan metode teknologi yang lebih canggih untuk mempromosikan lembaga kursus dan hasil karyanya agar dapat dinikmati oleh banyak orang. Berdasarkan permasalahan yang dijelaskan, dipilihlah website sebagai media yang dapat mengatasi permasalahan tersebut. Website dapat diakses oleh siapa saja karena website bersifat worldwide. Website juga dapat dikostumisasi sesuai keinginan agar terlihat unik, berbeda, serta menarik dan mudah untuk dibaca. Adanya website membantu kegiatan LKP Zere - Amin dalam melakukan kegiatan promosi lembaga kursusnya. Selain itu, website tersebut dapat dioperasionalkan dengan mudah oleh LKP Zere – Amin
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
