Judul: Sitotoksisitas Ekstrak Kulit Kayu Pinus merkusii Jungh. et de Vriese terhadap Sel Kanker Serviks HeLa
Abstrak: Cervical cancer is the most common death cause of cancer in Indonesian women. One of the efforts of cancer treatment is the utilization of natural materials compounds. Some plants have potential as anticancer, one of them is bark of Pinus merkusii. The purpose of this study was to determine the cytotoxic activity of Pinus merkusii bark extract against HeLa cells by microculture tetrazolium technique (MTT) assay. The study also tested the phytochemical content and the initial screening of cytotoxicity with Artemia salina. The Highest yield of 70% ethanol P. merkusii bark extract was 6.30%. Pinus merkusii contains flavonoids, triterpenoids, saponins and tannins. The results of cytotoxicity assay using A. salina showed that the Pinus merkusii bark extract has activity and potential as anticancer indicated by its LC50 values < 1000 μg/mL. The 70% ethanol extract of P. merkusii bark has highest cytotoxic activity against HeLa cells with IC50 value of 266.01 μg/mL which was higher than methanol, water, and aceton extract with IC50 values for respectively 408.13 μg/mL, 433.51 μg/mL, dan 880.24 μg/mL.

Judul: Potensi Antikanker Ekstrak Daun Sirih Merah (Piper crocatum) terhadap Sel HeLa
Abstrak: Cervical cancer is the most common death cause of cancer in Indonesian after human breast cancer. One of the efforts of cancer treatment is the utilization of natural materials compounds. Some plants have potential as anticancer for example leaves of Piper crocatum. Base of previous study methanol extract Piper crocatum has IC50 values 44.25 μg/mL on breast cancer cells (T47D). The purpose of this study was to determine inhibition activity of Piper crocatum ethanol, waters extract and Piper crocatum leaves powder against HeLa and Chang cells by Microculture Tetrazolium Technique (MTT) assay. The result showed that Piper crocatum leaves powder has higher inhibition with value 86% at 800 ppm which was higher than water and ethanol 30% with % inhibition 46% at 800ppm and 39% at 400 ppm.

Judul: Penerbangan Otomatis Pesawat Tanpa Awak Jenis Sayap Tetap dengan iNav
Abstrak: Pesawat tanpa awak (UAV) dapat dikendalikan secara manual dengan remote control atau secara otomatis dengan flight controller (FC). Salah satu jenis UAV adalah sayap tetap yang memiliki bentuk seperti pesawat terbang pada umumnya. Penelitian ini bertujuan untuk melakukan penerbangan otomatis pada UAV jenis sayap tetap dengan mengkonfigurasi perangkat FC. UAV yang digunakan adalah model SkySurfer X8 dengan bentang sayap 1.4 m. FC yang digunakan adalah Matek F405-Wing yang dikonfigurasi dengan perangkat lunak iNav. Berdasarkan hasil uji terbang, UAV berhasil terbang secara otomatis mengikuti skenario yang diberikan. Skenario terjauh berupa persegi berukuran 600×600 m pada ketinggian 100 m, yang ditempuh dalam waktu sekitar 2 menit dengan kecepatan sekitar 65 km/jam. Diharapkan prosedur perakitan, konfigurasi, operasi, dan hasil data uji terbang dapat menjadi acuan dalam penelitian selanjutnya.
