Blue Economy adalah usaha memanfaatkan  potensi sumber daya laut berbasis lingkungan dalam menunjang pertumbuhan ekonomi masyarakat wilayah pesisir. Pengabdian kepada Masyarakat (PKM) sebagai bagian dari program Kedaireka Matching Fund Direktorat Pendidikan Tinggi ini, dilakukan di wilayah Lemukutan untuk tujuan meningkatkan keterampilan  dan kesejahteraan masyarakat pesisir  melalui kegiatan Implementasi Blue Economy Melalui  Kegiatan  Budi Daya Rumput Laut E. cottonii di Wilayah Pesisir . Budidaya E. cottonii dilaksanakan dengan menggunakan metode longline, melibatkan sebanyak 15 orang mahasiswa dari berbagai program studi di lingkungan Universitas Tanjungpura serta 10 orang masyarakat setempat, selama 4 bulan berkegiatan. Kesuksesan usaha  budidaya rumput laut sangat tergantung pada pemilihan lahan dengan parameter lingkungan yang mendukung pertumbuhan dan perkembangan rumput laut, teknik serta metode budidaya yang sesuai. Kegiatan PKM ini menggunakan metode ceramah, simulasi di darat kemudian dilanjutkan dengan praktek langsung menanam rumput laut E. cottonii di wilayah perairan Lemukutan. Dari hasil kegiatan ini menunjukkan kemampuan masyarakat menggunakan metode long line dalam budidaya rumput laut E. cottonii sudah sangat memadai, dengan pengamatan selama 50 hari menunjukkan pertumbuhan relatifve sebesar 220,50%, dan  pertumbuhan harian 3.36 %. Penanaman rumput laut harus memperhitungkan intensitas matahari untuk memaksimalkan berlangsungnya fotosintesis serta menghindari penanaman di masa menjelang ekstrim di mana terjadi curah hujan tinggi dan gelombang laut yang kuat. Blue Economy Implementation Through Eucheuma cottonii Seaweed Cultivation Activities in the Coastal Area of ??Lemukutan Island  Blue Economy is an effort to exploit the potential of marine resources based on the environment in supporting the economic growth of coastal communities. Community Service (PKM) as part of the Directorate of Higher Education's Kedaireka Matching Fund program, is carried out in the Lemukutan area for the purpose of improving the skills and welfare of coastal communities through Blue Economy Implementation activities through E. cottonii Seaweed Cultivation Activities in the Coastal Area. The cultivation of E. cottonii was carried out using the longline method, involving as many as 15 students from various study programs at Tanjungpura University and 10 local people, for 4 months of activities. The success of seaweed farming is highly dependent on the selection of land with environmental parameters that support the growth and development of seaweed, appropriate cultivation techniques and methods. This PKM activity used the lecture method, simulations on land and then continued with direct practice of planting E. cottonii seaweed in the waters of Lemukutan. The results of this activity show that the community's ability to use the long line method in cultivating E. cottonii seaweed is very adequate, with observations for 50 days showing a relative growth of 220.50% and a daily growth of 3.36%. Seaweed planting must take into account the intensity of the sun to maximize photosynthesis and avoid planting at extreme times when there is high rainfall and strong sea waves.

This research is a research on a decision support system in choosing the best android emulator to use on a computer as a topic of discussion. The Android emulator is a software that supports computers, both laptops and other computer devices, to be able to continue to access Android in computer use by simulating Android to a computer device. In choosing an android emulator, problems often arise to use which emulator is the best and in accordance with the specifications of the computer you have, so for this conditioning, emulator experiments must be carried out one by one in an effort to ensure which emulator is of the highest quality and in simulating android on. Decision Support System can be a good approach in selecting an android emulator, with several criteria in determining the best android emulator, the VIKOR method is used because it has a multi-criteria basic concept. The VIKOR method is an approach in ranking alternatives to get the ideal and best solution with the criteria that have been owned and determined. In testing by managing data, it was found that the genymotion emulator had a final result of 0 and became the best emulator. By applying the VIKOR method, android users or emulator seekers, namely the community of game lovers or gamers, and android lovers will help to determine the ideal android emulator according to the specifications and the best emulator quality.
