Abstract

This research aims to produce media in the form of a ludo game for dividing numbers using porogapit multilevel division material that is effective, valid, effective and practical. This type of research is development research or can be called Research and Development (R&D) using the ADDIE stage model. The subjects of this research consisted of 18 class IV students at SD Negeri Mangunsari 01 Salatiga. The effectiveness trial was carried out by giving a pretest and posttest to students, then the results obtained were carried out by a t-test using SPSS Statistics 25. From the t-test results of the initial measurement and final measurement, the Sig value was obtained. (2-tailed) of 0.000. These results show that the Sig value. (2-tailed) < 0.05, then Ho is rejected and Ha is accepted, meaning that there is an influence in the use of the ludo game media for dividing numbers which can be said to be effective.

Abstract

BACKGROUNDAnopheles (An.) sp. transmits Plasmodium parasites that cause malaria. In its life cycle in the mosquito’s body, Plasmodium passes through 2 mosquito organs, namely the salivary glands and midgut. The bacterial community (symbiont bacteria) in these organs has been known to influence and/or inhibit the development of the Plasmodium life cycle by producing specific proteases. This research aims to isolate and characterize symbiotic bacteria with proteolytic activity from 2 important malaria vectors in Indonesia: An. sundaicus and An. vagus. METHODSA total of 183 bacterial originating from the salivary glands and midgut were successfully isolated. Initial screening was carried out based on morphological differences, followed by purification of the selected isolates to obtain single colonies. The selected isolates were then subjected to an initial proteolytic ability test using skim milk agar media. Only isolates with proteolytic activity were further characterized with the 16SrDNA molecular marker. The isolates were pabs5 from the salivary glands and pabs3 from the midgut of An. vagus, while pdbs3 and ecbs4 were isolates from the salivary glands and midgut of An. sundaicus. RESULTSMorphological and molecular characterization showed that both pabs5 and pabs3 isolates were Pseudomonas(Ps.) aeruginosa, while ecbs4 was Enterobacter cloacae and pdbs3 was Pantoea dispersa. These species werefirst discovered in Anopheles vagus and Anopheles sundaicus. CONCLUSIONThe ability of Ps. aeruginosa and Pantoea dispersa to produce proteases indicated their potential role in the exploration of new strategies to control mosquito vectors that transmit pathogens.

Abstract

Dionaea muscipula merupakan tumbuhan karnivora yang hidup di daerah terestrial yang kurang nutrisi khususnya nitrogen dan memiliki active snap trap. Tumbuhan karnivora ini memangsa serangga untuk memenuhi kebutuhan nitrogen dengan membentuk lobus berumbai yang akan menutup saat serangga mangsa masuk karena memiliki trigger hairs sebagai sensor. Lobus juga mensekresikan pigmen antosianin dan Volatile Organic Compounds (VOCs) untuk menarik perhatian serangga mangsa. Peran serangga selain menjadi mangsa juga berperan sebagai polinator, maka terjadi prey/pollinator paradox karena polinator dapat termangsa oleh D. muscipula. Maka dari itu, D. muscipula membentuk mekanisme dengan membentuk bunga sekitar 15-35 cm diatas jebakan. Mekanisme ini menyebabkan polinator yang berupa serangga terbang tidak termangsa oleh D. Muscipula dan membantu membawa polen. Mekanisme tersebut meminimalisasi overlapping antara serangga mangsa dan serangga polinator.
