Abstract POTENSIAL DEVELOPMENT OF EXTRACT BELUNTAS (Plucea indica Less.) as BIOLARVACIDE TO MOSQUITO Aedes aegypti LARVAE. The eradication of aegyptY mosquito is difficult because they have the ability to adapt environment which makes it very tough. Although, there are not disturbances due natural phenomena or human intervention. Termination life cycle an alternative reduce population. antimicrobial beluntas extract expected biolarvacide on larvae. biolarvasicide leaf extracts was determined...
Automotive growth in Indonesia continues to increase, thus the needed of material that supported such as lubricants have also increased. To support environment a sustainable development, world needs biodegradable lubricant or biolubricant. Biolubricant can match characteristics and replace function petroleum-based lubricants. The biolubricant base at moment was vegetable oil through series physically chemically modified. This research synthesizes used cooking into using natural zeolite...
Radiographers are one of the frontlines covid 19 patient services, including professions affected by pandemic. This study was conducted to prove effect Work Engagement (WE), Job Satisfaction (JS), Quality Life (QWL) and Stress (JSt) on radiographers Turnover intention (TI) during Covid pandemic, using an online survey Indonesian radiographers, collected 243 respondents used SEM-Amos analysis technique version 24 in its hypothesis test. The results that have a negative Intention, while does...
Sambiloto (Andigraphis paniculata) adalah tanaman medis tradisional digunakan untuk pengobatan dingin, demam, radang tenggorokan dan beberapa infeksi. Beberapa penelitian menunjukkan, sambiloto memiliki aktivitas antiinflamasi. Kemampuan senyawa aktifnya memberikan efek penghambatan secara tetap sampel ekstrak memenuhi standar yang ditetapkan BPOM RI. Hasil esktraksi dengan etanol air memberi informasi sebagai flavonoid. uji flavonoid dari terhadap enzim COX-2 sebeasar 98,97 % 16,70 %....
