Penggunaan sinar matahari sebagai sumber energi untuk. mengeringkan ikan tidak dapat dimanfaatkan setiap saat terutama  pada saat musim hujan. Hal ini menyebabkan banyak ikan yang terbuang sehingga dapat menyebabkan  pencemaran lingkungan. Penelitian ini dilakukan  dilapangan dengan membuat alat pengering (collector) dengan  ukuran 8 x 6 x 1,8 meter yang bertujuan unluk dapat mengeringkan ikan pada musim hujan. Ikan yang telah dikeringkan  dengan alat pengering collector kemudian dianalisa kadar basahnya dengan system oven di laboratorium kimia fisika Politeknik Negeri Lhokseumawe. Adapun metode penelitian ini dipakai adalah eksperimen bujur sangkar 3 x3, dimana setiap kali perlakuan diamati tiga kali;sehingga berjumlah 27 sampel. Dari hasil pengolahan data statistic dapai disimpulkan  bahwa ketebalan dan waktu penjemuran sangat mempengaruhi kekeringan lkan teri, dan tingkat kadar basah ikan yang sesuai adalah pada ketebalan diwaktu penjemuran 1cm dan 6jam.

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.

2017 has been a very productive and interesting year for our journal Light & Engineering/Svetotekhnika. It was marked by the publication of a large series of analytical reviews on the current state and prospects for the development of a number of important areas of lighting engineering (a total of 12 reviews), the publication of the regional volume of the Light & Engineering Journal (No. 3) devoted to solar energy technology in China (250 pages, 33 articles), further expansion of publications by international authors in Light & Engineering (since 2010, 120 articles by 230 authors from 23 countries have been published).
