Smart grid mobile application is a modernization in the consumption of electric power. Based on current research on smart grid mobile applications, it has investigated to the monitoring function, regulating, and scheduling energy consumption only. In the other case, the process of selling and buying electrical power is not inspected yet. This paper designed the user interface (UI) of smart grid mobile application in the process of selling and purchasing the electrical power. This combined Materials Design for Android (MDfA) with a design that adopts Common Element Sets (CES). The results of UI design were tested using usability and User Experience (UX). Usability test used System Usability Scale (SUS) and UX test used User Experience Questionnaire (UEQ). The results of usability testing obtained a score of 72 that was considered above average and included in the category "good". UX test in each aspect obtained a score as follows: attractiveness 1.925, perspicuity 1.975, efficiency 1.913, dependability 1.730, stimulation 1.938, and novelty 1.988. Overall UX testing results were included into the category "very good". Intisari-Aplikasi mobile smart grid merupakan modernisasi dalam konsumsi daya listrik. Saat ini, penelitian mengenai aplikasi mobile smart grid sampai pada fungsi pemantauan, mengatur, dan menjadwalkan konsumsi energi saja. Proses menjual dan membeli daya listrik belum ada. Makalah ini merancang user interface (UI) aplikasi mobile smart grid pada proses menjual dan membeli daya listrik. Desain UI aplikasi mobile smart grid menggabungkan penggunaan Materials Design for Android (MDfA) dengan desain yang mengadopsi Common Element Sets (CES). Hasil desain UI diuji menggunakan usability dan User Experience (UX). Usability test menggunakan System Usability Scale (SUS) dan Uji UX menggunakan User Experience Questionnaire (UEQ). Hasil uji usability mendapatkan skor 72 yang dianggap di atas rata-rata dan masuk dalam kategori "baik". Uji UX masing-masing mendapat nilai sebagai beikut:

Penelitian ini melakukan pengujian usability pada personal website. Pengujian fokus pada pemilihan terbaik antara penerapan sidebar kanan atau kiri. Pengujian usability menggunaan System Usability Scale (SUS). Pengambilan datanya menggunakan kuesioner yang diberikan ke responden berjumlah 16 pengguna. Responden terdiri dari 8 pengguna yang memiliki dominan tangan kanan dan 8 pengguna yang memiliki dominan tangan kiri. Hasil pengujian usability pada sidebar kanan mendapatkan skor 80 dan sidebar kiri mendapatkan skor 59. Dari hasil pengujian usability, sidebar kanan mendapatkan skor yang lebih tinggi. Selain pengambilan data menggunakan SUS, dilakukan juga wawancara kepada semua responden. Hasilnya pengguna lebih menyukai sidebar berada di sebelah kanan.

Media information has a very important role in efforts to attract prospective students to join. A website needs to be improved in the era of large technological developments. One of the new information media that utilizes the latest technology is a virtual tour. If you look at some of the previous ones, making a virtual tour can be made using panoramic photos made with image stitching techniques from many photos and can also use 3-dimensional engineering results. Both ways have their advantages and disadvantages. In this study, we will combine panoramic photos and 3D engineering to create a virtual tour of the Department of Electrical Engineering, Riau University. Virtual tour created using an equirectangular image base. There are 10 locations included in the virtual tour which four of them use panoramic photos and the remaining six places use 3D engineering. Four panoramic photos and six 3D-engineered equirectangular shapes are combined into one virtual tour. To validate the results of combining panoramic photos and 3D engineering into a virtual tour, user experience testing was conducted using a user experience questionnaire. User experience questionnaire was distributed to 30 respondents. As a result, four scales are in the excellent category: attractiveness, dependability, stimulation, and novelty. Then two scales are included in the good category, namely perspicuity and efficiency, which get a value of 1.78. From the user experience perspective, virtual tours resulting from a combination of panoramic photos and 3D engineering in general can be considered very good. Then this combination of panoramic photos and 3D engineering can be used as a solution for virtual tour documentation if several locations are inadequate to document

This study is focused on the institutional aspects as an essential prerequisite to the integration efforts of the coastal ecosystem restoration in Gresik and Malang regency. The purpose of this study was to perform coastal restoration with a "good governance" focus as a means of coastal restoration.The method to be used is to use Interpretive Structural Modeling (ISM) and Analytical Hierarchy Process (AHP). ISM is an interactive design methodology to develop structures that describe the relationship between elements. While AHP is a framework for effective decisions on complex problems.The results of this study is to show the formulation of the seven (7) priority structure. While the master plan drawn up leading to the respective roles of the stakeholders at the village level, district level, district level and provincial and national levels. While the preparation of the action plan was drawn up with reference to the 9 (nine) step restoration management in an integrated manner.

Serai wangi adalah alternatif dari sekian bahan baku untuk menghasilkan minyak atsiri. Minyak atsiri dapat berfungsi sebagai campuran kosmetik, aromaterapi, obat-obatan, suplemen, dan lainnya. Kegiatan pengabdian masyarakat ini bertujuan untuk menerapkan inovasi alat penyulingan minyak atsiri dalam bentuk produk teknologi tepat guna untuk meningkatkan hasil produksi minyak atsiri bagi petani di Desa Siabu, Kecamatan Salo, Kabupaten Kampar, Provinsi Riau. Masyarakat juga dapat mengetahui dan memahami, serta meningkatkan mutu rendemen agar kualitas minyak menjadi lebih baik sekaligus bemanfaat bagi masyarakat. Metode pelaksanaan terdiri dari survei lapangan, analisis situasi, rancangan alat, pemasangan alat, dan pemantauan alat pengumpulan data, dan analisis sesuai dengan teori-teori yang dikutip untuk memperoleh informasi. Dalam penyulingan minyak serai wangi terdiri dari tiga cara yakni; penyulingan menggunakan sistem rebusan, penyulingan menggunakan air dan uap, penyulingan menggunakan uap langsung. Hasil penyulingan serai wangi menjadi minyak atsiri dengan kapasitas 130kg per-ketel dapat menghasilkan minyak atsiri 1,3 liter
