The Effectiveness of Leaf Powders from Several Types of Plants as Botanical Insecticides Against Mung Bean Beetle Pest (Callosobruchus chinensis L.) in Storage

Mung bean (Vigna radiata L.) has the third economic value among the legume group in Indonesia, after soybeans and peanuts. In storage, mung beans are often attacked by the beetle pest Callosobruchus chinensis L.; thus, it is necessary to control these pests. One way to control it is by using botanical insecticides derived from several types of plants, including lime leaf powder, noni leaf powder, nutmeg leaf powder, and lemongrass leaf powder. The purpose of this study was to obtain the most effective type of plant powder in controlling C. chinensis pests on mung bean seeds in storage. The study was conducted at the Plant Pest Laboratory of the Faculty of Agriculture, Pattimura University, which took place from November 2020 to January 2021. The study was conducted using a Completely Randomized Design with 4 treatments, namely DJ (15 g of lime leaf powder per 100 g of mung bean seeds), DM (15 g of noni leaf powder per 100 g of green bean seeds), DP (15 g of nutmeg leaf powder per 100 g of green bean seeds), DS (15 g of lemongrass leaf powder per 100 g of green bean seeds) and K (control, without leaf powder). Twenty imagos of C. chinensis were used in each treatment, and the experiment had 3 replicates. The variables observed included the initial symptoms after treatment, the mortality rate of the test insects, and the mortality of the test insects. The results showed that the DS (lemongrass leaf powder) and DM (noni leaf powder) treatments resulted in the mortality of the test insects of 93.33% and 91.67%, respectively, and were more effective than the other two treatments, namely DP (nutmeg leaf powder) and DJ (lime leaf powder) as well as controls. &nbsp

Pemanfaatan Ekstra Daun Jambu Biji terhadap Kualitas Fisik Telur

Penelitian ini bertujuan untuk melihat seberapa efektif penggunaan ekstra daun jambu biji dalam peningkatan masa simpan telur ayam ras. Penelitian menggunakan telur ayam ras segar umur 1 hari sebanyak 120 butir. Rancangan dalam penelitian yakni Rancangan Acak Lengkap dengan 4 perlakuan dan 3 ulangan. Kombinasi dalam perlakuan ini diantaranya T0 dengan waktu penyimpanan 0 hari (kontrol), T1 dengan waktu penyimpanan 14 hari, T2 dengan waktu penyimpanan 17 hari dan T3 dengan waktu penyimpanan 21. Variabel dalam penelitian ini terdiri dari kedalaman rongga udara, haugh unit dan youlk indeks. Data hasil penelitian selanjutnya di analisis berdasarkan analisis Rancangan Acak Lengkap dan ketika menunjukkan adanya pengaruh nyata di lanjutkan dengan uji Duncan's Multiple Test (DMRT). Hasil penelitian menunjukkan bahwa perlakuan perendaman memberikan pengaruh terhadap kondisi kedalaman rongga udara telur ayam ras, sedangkan pada variabel haugh unit dan youlk indeks tidak memberikan pengaruh

International efforts to save healthcare personnel during COVID-19

: Coronavirus disease 2019 (COVID-19) pandemic is a global challenge. Several governments of the world have decided to take drastic actions in order to combat the spread of the disease, including the closing of air, maritime and land borders, as an extreme measure of isolation of each country/region. However, such measures had not prevented the disease from spreading globally; as COVID-19 has already spread in almost all countries. This virus's main victims are the healthcare personnel (HCP), who are physically and psychologically affected. The HCP serves as the first line of defense against this pandemic, what if we faced a significant loss in their number? And what if our HCP was going through a deep dark depression? The condition would be terrifying not only for now but also in the future. This raises the need for an intensified International collaboration, that mainly supports the HCP. We are throwing by challenging moments, and it is clear that social distancing, cooperation, hygiene awareness and abide by the recommendation and help of all governments, as well as obtaining the support of international organizations could be an excellent tool for preventing an increase in the number of cases, principally in countries and regions were COVID-19 is in the early stage of the epidemic. However, this is not the final solution for the current pandemic. An intensified global program, which mainly supports the HCP, then considers the other aspects of the COVID19 pandemic might bring this pandemic to a peaceful end
