Judul: Kandungan Pati dan Kurkuminoid Simplisia Kunyit (Curcuma domestica Val.) sebagai Parameter Pemilihan Aksesi Terbaik
Abstrak: The quality of simplicia as medicine raw materials determined by percentage of certain metabolites components contained in the simplicia. The selection of turmeric best accession based on curcuminoids content as the main component and starch content as a matrix constituent. This research aimed to analyze adaptability of plants from its genetic effects of turmeric towards curcuminoids and starch content of turmeric simplicia from several accession to acquire best accession with high curcuminoids and low starch. The accession that were used such as BPTO, Ciemas, Nagrak, Ngawi, Wonogiri, and the last two from Balitro Bogor best varieties i.e. Turina-1 and Turina-2. Starch measurement used Luff-schoorl methods. Curcuminoids were measured using HPLC. Starch content of all sample is 2.361-3.421%. Turina-1 have lowest starch content is 2.361% and followed by accession of Ciemas is 2.565%. Curcuminoids contents of all sample is 4.776-5.793%. Accession of Ciemas have highest curcuminoids content 5.793%. Accecions from Ciemas selected for best accecions because it has high curcuminoids and low starch content.

Judul: Kandungan Kurkuminoid, Inhibisi a-Glukosidase dan Sitotoksisitas Ekstrak dari Beberapa Aksesi Kunyit (Curcuma domestica Val.)
Abstrak: Turmeric (Curcuma domestica Val.) is a medicinal plant family Zingiberaceae with curcuminoid content of the rhizome. This study aims to determine the content of curcuminoid, α-glucosidase inhibitory activity, and cytotoxicity test curcuminoids of turmeric extracts from several accessions. Curcuminoid content analysis was performed using HPLC. Inhibition of α- glucosidase performed in vitro with the substrate p-NPG. The cytotoxicity of curcuminoid extract of turmeric using BSLT method. The highest levels of curcuminoid owned by Ngawi, followed by Ciemas, Wonogiri, and Nagrak. Levels curcuminoids Ngawi of 24.50%. Turmeric extract the highest bioactivvity as α-glucosidase inhibitor activity is Nagrak accession with IC50 values of 207.093 μg/mL. Cytotoxycity test results showed that all samples have bioactivity and accession have the best LC50 value is Karanganyar at 19.090 μg/mL. Nagrak, Wonogiri, and Ngawi, has the potential to be developed into new varieties of turmeric with high bioactivity in inhibition α-glucosidase with IC50 moderate level.

Judul: Rancang Bangun Sistem Komunikasi Data Lokasi Robot Beroda dan Server Berbasis Wi-Fi Menggunakan Modul ESP8266
Abstrak: Robot beroda merupakan salah satu jenis robot yang banyak dikembangkan. Sistem komunikasi data antara robot dan server banyak diterapkan pada sistem kerjasama antar-robot, ketika robot memerlukan informasi terkait robot lainnya. Penelitian ini mengembangkan sistem komunikasi data nirkabel berbasis Wi-Fi menggunakan modul ESP8266. Data diambil menggunakan modul GPS Ublox Neo 6MV2 yang terhubung dengan satelit lalu dikirim dan disimpan di server untuk kemudian digunakan sesuai kebutuhan. Selanjutnya, pengiriman data dari server ke robot disimulasikan dengan pengiriman balasan oleh server bahwa data sudah diterima. Selanjutnya robot akan merespon balasan dari server tersebut dengan menyalakan light emitting diode (LED) sebagai notifikasi. Hasil dari penelitian ini adalah sistem komunikasi data secara real time dengan menggunakan modul ESP8266 berhasil diimplementasikan dengan interval pengiriman data sebesar 33.29ms dan tingkat keberhasilan pengiriman data keseluruhan sebesar 100%.
