Aedes aegypti mosquito is the main vector of dengue virus causing dengue hemorrhagic fever (DHF) in Indonesia. The main preventive action is to control the presence of Ae. aegypti mosquito. Banana plants are known to contain secondary metabolite compounds acting as a natural insecticide, including the hump part. This research was conducted to evaluate to toxicity of hump of Ambon banana extract (Musa acuminata L. cv. Gros Michel) to dengue vector Ae. aegypti mosquito. The research used experimental method, the treatment concentration was 0.001; 0.01; 0.1; 1; 10; 100 and 1000 ppm of Ambon banana methanol extract and 0 ppm concentration as a control, each with three replications. The variables observed were individual deaths at every stage of development and morphological damage. The data obtained were analyzed using the analysis of variety and Duncan test with 95% confidence level. In addition, probit analysis was used to determine the value of LC50. The results showed that the study of toxicity indicates that in the further stage of development, the toxicity of methanol extract from Ambon banana hump was less toxic. Toxicity of Ambon banana hump methanol extract was highest in egg with LC50 value of 314,852 ppm. The methanol extract of banana Ambon has the morphological destructive activity in all development stages of Ae. aegypti.Abstrak. Nyamuk Ae. aegypti merupakan vektor utama virus dengue penyebab demam berdarah dengue (DBD) di Indonesia. Upaya pencegahan utama adalah dengan mengendalikan keberadaan nyamuk Ae. aegypti. Tanaman pisang diketahui memiliki kandungan senyawa metabolit sekunder yang memiliki aktivitas sebagai insektisida nabati, termasuk bagian bonggol. Penelitian ini dilakukan untuk mengevaluasi daya toksisitas ekstrak metanol bonggol pisang ambon (Musa acuminata L. cv. Gros Michel) terhadap nyamuk vektor dengue Ae. aegypti. Metode penelitian yang digunakan adalah metode eksperimental dengan desain penelitian rancangan acak lengkap (RAL), perlakuan yang dicoba berupa konsentrasi ekstrak metanol bonggol pisang ambon 0,001; 0,01; 0,1; 1; 10; 100, 1000 ppm dan 0 ppm sebagai kontrol, masing-masing dengan tiga kali ulangan. Variabel yang diamati adalah kematian individu pada setiap tahap perkembangan dan kerusakan morfologi. Data yang diperoleh dianalisis menggunakan analisis ragam dan uji duncan dengan taraf kepercayaan 95%, dan untuk menentukan nilai LC50 menggunakan analisis probit dengan aplikasi SPSS 16. Hasil penelitian menunjukkan bahwa semakin lanjut tahap perkembangan nyamuk Ae. aegypti, ekstrak metanol bonggol pisang ambon semakin tidak toksik. Daya toksik ekstrak metanol bonggol pisang ambon paling tinggi pada telur dengan nilai LC50 314,852 ppm, dengan aktivitas berupa penghambatan penetasan telur, sedangkan paling rendah pada imago dengan nilai LC50 1755,077 ppm. Ekstrak metanol bonggol pisang ambon memiliki aktivitas merusak morfologi semua tahap perkembangan Ae. aegypti.
The ability of the predatory mite Phytoseius amba resistant temperature (results of superior applied research in 2018-2019) in controlling the spider mite Tetranychus urticae has not been stable in the long dry conditions in 2019. The instability of ability indicated by the decreased survival of temperature-resistant P. amba is closely related to various ecological factors, namely temperature, humidity, rainfall, sunshine intensity, leaf angle, density, and size cassava cultivar trichome and intra- and inter-species competition. Augmentation is an effort to release the mass of temperature-resistant P. amba predatory mites based on ecological factors. This biocontrol agent is still useful in playing a role in global warming conditions. The first-year research (2020) aims to determine the survival of P. amba resistant to temperature on a field scale and obtain key ecological factors that determine the survival of temperature-resistant P. amba local predator mites in cassava gardens in Banyumas Regency. The method used in the first year (2020) field-scale research was a survey with a random sampling technique. Samples were taken from the leaves of the Martapura cultivar in Cilacap. Data were analyzed using a randomized model variance analysis at an error rate of 0.1. The variance analysis results showed that among the temperature, humidity, rainfall, the density of adult T. urticae, nymphs, larvae, and eggs, the density factor of adult T. urticae mites was an ecological factor that determined the density of temperature-resistant P.amba mites on the field scale.
Language is not always neutrally utilized by a politician. It is framed to persuade people to think and act in line with the intention of the orator or the ideology of the group he represents. This study dealt with ideological discourse analysis of Obama speech in Cairo. It focused on the cognitive processes showing the link of the ideology structure and discourse structures. This study was (1) to identify the underpinning ideology of the speech, (2) how the ideology structure link withthe discourse structures employed, covering (a) how the ideology was expressed at global meaning level and at local meaning level, (b) how propositional structures were employed as ideology controlled strategy, (c) how sentence syntax was employed as ideology –controlled strategy, (d) how discourse forms or genres were employed as an ideology-controlled strategy, and (e) how styles were employed as persuasive ideology-controlled strategy in his efforts to frame peace. The framework of the research was Critical Discourse Analysis in general and Ideological Discourse Analysis in particular. So Ideological Discourse Analysis in this study was employed as Theory and Method. The data were the text of Obama’s speech in Cairo 2009. The data in the form of quotes were analyzed, and interpreted by employing Critical Discourse Analysis (Fairclough, 1995) to uncover the underpinning ideology of the speech, and Ideological Discourse Analysis to show the link of the ideology structure and the discourse structures employed in the speech. The results were in the form of the description of the cognitive processes showing how the underpinning ideology was expressed at different levels of discourse structures for the purpose of framing peace.
Living among the virus covid-19 epidemic, lecturing was conducted online. One such learning technique is the storyboard technique. The media picture (storyboard) is a media that is a reproduction of the original form in dimensions, in the form of photographs or paintings. Storyboard technique is activity before writing that emphasizes the elaboration (detailed explanation) predictions or estimates, the growth of ideas, and sequencing. This study aims to (1) describe the process of pre- developing of a storyboard, (2) show a model of the sequence of the story of storyboard (3) show an inspiring lesson plan of teaching writing of narrative text online using storyboard technique. The design of this study is descriptive qualitative. The design of this study is descriptive qualitative. The research framework is semantic construction, specifically limits the focus on coherence. The construction of the pre-developing of the storyboard is built on two concepts: building the coherence theory of van Dijk's building text and the generic structure of the narrative text. The result of this study are (1) In order to produce a storyboard in creating narrative text, the teacher should simplify the global coherence of complex story to the local one, after that it is continued by the technique of visualization as following the generic structure of a narrative text (2) The storyboard is drawn digitally (3) The lesson plan of teaching using this technique
Pada Penelitian Internal UNUSA tahun 2020, penulis membuat penelitian dengan judul "Storyboard as Media of Writing Narratives for Online Teaching and Learning Process during the Lock down period of the virus convid-19 outbreak". Sebuah penelitian berbentuk Descriptif Qualitatif yang menjelaskan tentang salah satu alternatif media pengajaran yang bisa diterapkan di masa pandemi yang sering dalam bentuk daring. Dalam pengabdian masyarakat tahun 2021 ini, penulis menerapkan penelitian tersebut dalam bentuk workshop. Workshop ini penulis bergabung dengan kegiatan Pengabdian Masyarakat yang bertema besar "UNUSA PEDULI" yang dilaksanakan selama 2 minggu oleh Fakultas Keguruan dan Ilmu Pendidikan yang bekerjasama dengan Dinas Pendidikan Magetan dan PGRI Magetan. Kegiatan tersebut telah dilaksanakan dengan sukses dan peserta diberikan sertifikat workshop. Luaran dari kegiatan ini adalah artikel pada jurnal SNPM.
