One of the conditions for ensuring the safety of air transport operation is the quality of aviation fuel refueled in aircraft. Fuel quality control is a multi-parameter task that includes monitoring the free moisture content. Regulatory documents establish the content of free water no more than 0.0015% by weight. It is developed a direct electrometric microwave resonance method for controlling free moisture in aviation fuels, which consists in changing the shape of the water drops by pressing them on a solid surface inside a cylindrical cavity resonator. This can dramatically increase dielectric losses. Analytical and experimental analysis of the proposed method is carried out. The control range from 0,5 to 30 μl of absolute volume of moisture in aviation fuels with a maximum error of not morethan 25 % is justified. The sensitivity of the proposed method for monitoring microwave losses in free moisture drops transformed into a thin layer by pressing is an order of magnitude greater than the sensitivity of the method for monitoring microwave losses in moisture drops on a solid surface in a resonator. The proposed method can be used as a basis for the development of devices for monitoring the free moisture of aviation fuels in the conditions of the airfield and laboratory. The direction of development of the method is shown.

The anthelmintic resistance has limited the control of gastrointestinal nematodes of small ruminants and thus has awakened interest in the study of plants extract as a source of anthelmintics. These experiments were carried out to evaluate the in vitro efficacy of Jatrophacurcas latex extract against Haemonchuscontortus larval motility. To evaluate the larvicidal activity, H.contortus L3 were incubated with the extracts with varying concentration of 5 mg/mL, 10 mg/mL, 15 mg/mL and 20 mg/mL at 27°C for 48, 72 and 96 hrs. The results were subjected to the Kruskal-Wallis test (P less than 0.05). The extracts showed dose-dependent larvicidal effects. These results suggest that J.curcas can be used to control gastrointestinal nematodes of small ruminants.

Propeller planes and small engine aircraft around the United States, legally utilize leaded aviation gasoline. The purpose of this experiment was to collect suspended particulate matter from a university campus, directly below an airport’s arriving flight path’s descent line, and to analyze lead content suspended in the air. Two collection sets of three separate samples were collected on six separate days, one set in July of 2018 and the second set in January 2019.

Indonesia memiliki banyak  tanah masam, tetapi penggunaan masih sangat sedikit karena kandungan nutrisi tanah masam rendah. Sementara itu, jarak pagar merupakan tanaman yang dapat tumbuh di berbagai jenis tanah (termasuk lahan marjinal) dan penggunaannya sebagai bahan baku biodiesel. Oleh karena itu, perlunya penelitian mengenai pertumbuhan jarak pagar pada tanah masam sebagai upaya untuk mengembangkan jarak pagar dan penggunaannya di Indonesia.Untuk memulai upaya, penelitian tentang berbagai genotipe jarak pagar di tanah masam telah dilakukan. Tujuan dari penelitian ini yaitu mempelajari genotipe jarak pagar  yang berpotensi untuk tanah masam. Penelitian ini dilakukan di UPTD Pengembangan Teknologi Lahan Kering Singabraja, Kecamatan Tenjo, Bogor, Jawa Barat, dari November 2010-Agustus 201. Penelitian ini menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) dengan satu faktor yaitu genotipe. Hasil penelitian menunjukkan berbagai perbedaan pada pertumbuhan diantara genotipe-genotipe jarak pagar. Secara umum, ada lima genotipe jarak pagar yang terbaik di tanah masam (pH 5.0) yaitu Medan I-5-1, Dompu, IP-2P-3-4-1, Sulawesi, dan Bima M.
