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 dan Daya Antioksidan Aksesi Temulawak (Curcuma xanthorrhiza Roxb.) asal Sukabumi
Abstrak: Curcuma xanthoriza Roxb. is one kind of curcums which useful as medicine plants. It containts curcuminoid which has antioxidant bioactivity. This study aimed to measure curcuminoids content and antioxidant bioactivity of Ciemas (Sukabumi) accessions compared with varieties of Kursina 3 from Bogor. HPLC method were used to determined curcuminoid content. The antioxidant bioactivity of both samples were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical method. Percent yield ethanol 70 % extract of Curcuma xanthoriza Roxb. were 15.85 % (Kursina 3) and 19.94 % (accession). The curcuminoid content of Kursina 3 and acccession were 0.79 % and 0.99 %, respectively. The result of IC50 were 82.8 ppm (Kursina 3) and 47.97 ppm (accession) respectively. Based on the result of the study, Sukabumi promising lines curcuma has the potential to be further researched and developed as new varieties.

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%.
