Abstract

The banana weevil, Cosmopolites sordidus Germar, is an important pest of highland banana and plantain in Africa, but it exists in low densities in presumed area of origin in Southeast Asia such as in Indonesia. This suggests a possible existence of effective co-evolved natural enemies in the origin area of Indonesia, especially West Sumatra. The objectives of this study were: (1) to evaluate banana weevil pest status at selected sites in West Sumatra, (2) to survey parasitoids and predators, and(3) to determine the control potential of the most important natural enemies. Surveys were undertaken in March 2002-August 2003 in five locations in West Sumatra, i.e., Bukittinggi, Sitiung, Pariaman, Pasaman, and Batusangkar. Five farms per site were selected randomly among all farms that contained banana stands of > 0.5 ha. Sampling for banana weevil adults and damage, and for predators was done throughout small banana stands and within a 20 m x 40 m (0.08 ha) subplot on largerfarms. Field-collected larvae were taken to the laboratory and reared on corm pieces (3 cm x 3 cm x 3 cm) until pupation. Larvae were collected from pseudostem as well as corm residues. To estimate the abundance of non-social predators, i.e., those other than ants, 10 residues each on each farm were examined from plants that had been harvested 1-4 weeks, 5-8 weeks or 9 or more weeks before our visit to the site. Samples of thedifferent morphospecies were saved in alcohol for later identification. The result showed that the banana weevil incidence was found to be low,  0.6-1.7 adults per trap. Plant damage indices were below 2.2%. We collected and reared 24,360 eggs and 3118 larvae, but no parasitism was detected. Phorids (Megaselia sp.) and drosophilids were recovered from larval rearings, but most likely were scavengers. A complex of predators was detected, the most important of which was the histerid beetles,  Plaesius javanus Erichson. In laboratory tests, adults and larvae of P.  javanus attacked 75-88% and 38-53% of banana weevil larvae and pupae, respectively. Predatory ants, including species of Myrmicinae, Ponerinae, Formicinae, and Dolichoderinae, were found to be associated with bananaplants and residues. Adults of Myopopone castanea Smith (Ponerinae) were directly observed attacking banana weevil larvae in crop residues. The adult banana weevil mortalities caused by the entomopathogen fungi of Beauveria bassiana from Baso, Sungaitarab, Sei Sariek, and Sikabau at highest density (3.2 x 108 spores ml-1) after two weeks were 96.67%, 90.00%, 60.00% and 83.33%, respectively. The high diversity of habitatconditions in which crop-pest-natural enemies systems exist, support the idea that banana weevil population and damage intensity in the study area is low due to active role of natural enemies.

Abstract

Kabupaten Musi Banyuasin (Muba) merupakan kabupaten terkaya di Sumatera Selatan dan mempunyai banyak aliran sungai yang dapat dijadikan ruang lalulintas angkutan sungai. Dengan menggunakan metode analisis deskritif dan AHP diperoleh 4 titik simpul potensial angkutan sungai yang perlu dikembangkan, yaitu terminal  P 11 yang berada di Muara Primer untuk konsolidasi muatan/ komoditi yang hendak diangkut ke luar Provinsi Sumatera Selatan, terutama menuju P. Jawa, Batam, bahkan ke luar negeri, Dermaga Sungai Lalan dan Dermaga Sungai Lilin dikembangkan untuk kebutuhan angkutan komoditi lokal masyarakat di sekitar aliran sungai, terutama yang berasal/ menuju kota Palembang,  selain itu juga dapat digunakan sebagai angkutan feeder bagi perusahan-perusahaan guna mendistribusikan komoditinya dan/ atau menuju titik simpul utama untuk konsolidasi muatan, untuk selanjut dibawa keluar, dan Dermaga Sekayu, yang berada di Kota Sekayu, dikembangkan menjadi dermaga angkutan orang dan pariwisata, selain itu juga dijadikan dermaga persinggahan bagi komoditi yang ada di wilayah kabupaten lain.

Abstract

This research aims to produce learning video media for SKI Class VII MTsN subjects that are valid and practical. This type of research is development research, known as Research and Development (R&D), using the 4-D development model. The development procedure in this research consists of 4 stages, namely, (1) Define, (2) Design, (3) Develop, (4) Disseminate. The product validity test was carried out by 3 validators, namely 1 material validator and 2 media validators. Product trials were carried out on class VII students at MTsN 5 Tanah Datar with the aim of finding out the practicality of the product being developed. The results of material validation by material expert validators obtained an average of 4.94 in the "very valid" category. The results of the media validator assessment with validator I obtained an average of 4.93 in the "very valid" category and the validation results with validator II obtained an average of 4.93 in the "very valid" category. This learning multimedia is said to be practical based on the results of the practicality test with an average of 4.5. Based on the results of the validity test and practicality test, it can be concluded that learning multimedia in PAI subjects for class IV elementary school is suitable for use in learning

Abstract

Digital classes students follow learning by listening to the teacher's briefing that enters the class, using various needs for learning such as LKS, textbooks, and other media. This study aims to determine the effectiveness of digital classroom learning in the subject of Information and Communication Technology in grade VII of SMP Negeri Payakumbuh. The type of research is quantitative research with a sample of 38 where in this quantitative research uses many numbers. The research method used is a quasi experiment. Data collection is carried out through tests, and data analysis is carried out using t-tests. The results of the study showed that the average score obtained in ICT subjects using google classroom on student learning outcomes was higher than the average score in the control class that used paper sheets. Thus, the t-count is smaller than the t-table, which can be interpreted that there is a significant effectiveness on student learning outcomes between classes that use google classroom in digital classrooms.

Abstract

This research is motivated by the low learning outcomes of students in Informatics subjects caused using a learning model that is still centered on teachers and the limited use of learning media. The purpose of this study is to find out whether there is an effect of the use of the Problem Based Learning (PBL) model assisted by wordwall media on student learning outcomes in informatics subjects at SMAN 1 Gunung Talang. The research was conducted using a quantitative method using Quasy Experimental Research. The population of this study is 305 students of class X with a sample of 50 students selected using the purposive sampling technique. Data analysis using t-test. The results of data analysis showed that the average post-test score of students in the experimental class was 78.40, while in the control class it was 64.68. Statistical testing shows that the tcount value of 10.78 exceeds the ttable value of 2.01 at a significant level α 0.05. Thus, it can be concluded that the problem-based learning model assisted by wordwalls has a significant impact on the learning outcomes of students in Informatics subjects at SMAN 1 Gunung Talang

Abstract

This research aims to produce multimedia learning in informatics subjects using a 4D (four-D) development model which includes four stages, namely define, design, development, and dissemination. In the Development Step, a media validity test was carried out with two media expert validators and one material expert validator, then a practicality test was carried out on 30 junior high school grade VIII students to test the practicality of the multimedia learning developed. The results of the media validity assessment with validator I got a percentage of 94.67 with the category "very valid" and the results with validator II got a percentage of 97.33 with the category "very valid". The validity of the material obtained by the material validator obtained a percentage of 96.36 with the category of "very valid". Multimedia learning is said to be practical based on a practicality test with a percentage of 95.43 with the category "very practical". The steps taken in analyzing the respondents and then finding the percentage of the average results can be determined by the assessment criteria for the practicality test. Based on the results of the validity and practicality test, it can be concluded that the learning multimedia product in the informatics subject is very feasible to be used in the learning process.
