Wakatobi National Park has a diverse fish population, and its conservation potential for reef fish resources is quite large. As a result, to be sustainable, the exploitation of these resources must be properly managed. This study aims to look into the characteristics of reef fish fisheries, such as species composition, catch, fishing ground, and fish length. The outcomes are hoped to be beneficial in monitoring the management of the resources. This research was conducted in April-November 2018 in Wakatobi, Indonesia. Analytical methods process the data. The results showed that gold spotted rabbitfish (Siganus punctatus), parrotfish (Hipposcarus longiceps), emperor (Lethrinus lentjan), grouper (Epinephelus sp), and trevallies (Caranx sp) dominated the total catch from muroami, speargun, and hand line. Muroami boats have a higher average CPUE (212 kg/trip/month) than speargun (29.0 kg/trip/month) and handlines (13.0 kg/trip/ship). Some of the reef fish caught in Wakatobi National Park is small and immature. Muroami net, speargun, and handline fishing are mostly done in the southern part of the Wakatobi National Park area, around Binongko Island. One of the management actions undertaken by Wakatobi fishermen is fishing inside the management zone that has been established, namely the local use zone.

Sclerotium rolfsii is the causal organism of the damping-off disease of soybean. Control of this disease is usually carried out by using chemical fungicides that have a negative impact on the environment. One of the efforts to overcome this problem is by using botanical fungicides from plant extracts. This study aims to determine the effect of plant extracts from Alpinia purpurata, Zingiber officinale, Curcuma longa, Curcuma xanthorrhiza, and Kaempferi galanga on the in-vitro growth of Sclerotium rolfsii and on the in-vivo of damping-off disease of soybean. In addition, a phytochemical test was also undertaken to determine the content of secondary compounds found in plant extracts. The experiment was carried out at the Chemistry Laboratory of the Faculty of Mathematics and Natural Sciences, Microbiology Laboratory and a Greenhouse of Faculty of Agriculture at the University of Mataram, from July until October 2020. The experiments used a completely randomized design (CRD) with seven treatments and three replications. The seven treatments were A. purpurata, Z. officinale, C. longa, C. xanthorrhiza, and K. galanga with a concentration of 5% (v/v), control (+), and the alcohol (-). The results showed that the extracts of A. purpurata, Z. officinale, C. longa, C. xanthorrhiza, and K. galanga with a concentration of 5% could suppress the growth of S.rolfsii by in-vitro. However, in the in-vivo trial, no extracts could suppress damping-off disease of soybean.

Vegetation cover changes information is essential in forest and plantation management. Low-resolution remote sensing in mosaic data format has been widely used for vegetation cover change mapping on a global scale by implementing the threshold method. However, the problem with this method in Landsat-8 - which has a higher resolution - is that it is challenging to obtain the appropriate value due to the diversity of Indonesia’s land ecosystems. This research aimed to determine the threshold value for detecting devegetation and revegetation to identify vegetation cover changes rapidly. This research used Oldeman Climate Classification with zone A and B as the references. The threshold values to classify vegetation cover changes were derived from the delta Normalized Burn Ratio (dNBR) of Analysis Ready Data (ARD) Landsat-8 - taken in Sumatera as the pilot area. Moreover, the proposed method was also applied to Kalimantan and Java Islands, with have identical climates. The results indicated that dNBR threshold for devegetation was more than 0.376, while revegetation was less than -0.269. These results were evaluated using high-resolution satellite imagery and ground-truth information. It concluded that Kalimantan Island obtained good results in mapping vegetation cover change with the threshold; however, Java Island required further adjustment for the threshold.

Hemostasis is a complex physiological process aiming to keep the integrity of a closed circulatory system after an occurrence of vessel wall injury. Hemostasis involving the role of circulating platelets and coagulation cascade.1 There are two major pathways that act independently to activate the platelet. The first pathway is mediated by collagen and the other by tissue factor. After intimal layer injury, platelets are recruited through the interaction between platelet’s surface glycoprotein (GPVI and GPIb/V/IX) with collagen and von Willebrand factor. This process results in adhesion of platelets in the site of injury. Further recruitment of platelets is achieved by secretion of aggregatory mediators such as thromboxane A2 and adenosine diphosphate.
