Abstract

Ladybird beetle, Henosepilachna vigintioctopunctata Fabricius (Coleoptera: Cocinellidae) has a wide host plants belonging to family of Solanaceae. The species can be a serious pests of solanaceous crops, such as, eggplants and potatoes. The aims of the research were to study life table and to measure demography parameters of H. vigintioctopunctata fed by leaves of Solanum torvum, S. nigrum, S. melongena, and Brugmansia suaveolens. Results showed that the highest longevity (68.7 days, male and 79 days, female) occurred in H. vigintioctopunctata fed by leaves of  S. nigrum, followed by S. torvum (20.6 days, male and 31.7 days, female), S. melongena (1.5 days, male and 2.5,0 days, female, and B. suaveolens (1.8 days, male and 1.7 days, female). Based on demography parameters, the highest net reproductive rate occured in H. vigintioctopunctata fed on leaves of S. torvum (R0 = 2.11 individu), followed by S. nigrum (R0 = 0.64 females/female), S. melongena (R0 = 0.06 females/female), and B. suaveolens (R0 = 0.006 females/female). Generation time was high in H. vigintioctopunctata fed by S. nigrum (28.53 days) and S. torvum (27.42 days) compared to S. melongena (5,9 days) and B. suaveolens (2.5 days). Intrinsic growth rate of H. vigintioctopunctata was highest in S. torvum (r = 0.0094 females/female/day). Based on the life table and demography parameters, S. torvum is the most suitable plant for growth and development of H. vigintioctopunctata.

Abstract

Penelitian ini bertujuan untuk menganalisis minat siswa kelas khusus olahraga (KKO) terhadap pembelajaran Informatika, khususnya pada materi APP Inventor dalam pengembangan proyek aplikasi kalkulator. Penelitian dilakukan di kelas XI F KKO SMA Negeri 4 Surakarta dengan melibatkan 25 siswa sebagai responden. Metode yang digunakan adalah survei dengan menggunakan kuesioner yang dirancang untuk mengukur aspek-aspek minat belajar seperti kesenangan, ketertarikan, kepuasan, motivasi, keinginan, dan keingintahuan. Selain itu, observasi dan wawancara dengan guru juga dilakukan untuk memperoleh pemahaman yang lebih mendalam. Hasil analisis data menunjukkan bahwa mayoritas siswa (68%) berada dalam kategori "Cukup Berminat", sementara 20% siswa berada dalam kategori "Berminat" dan 12% siswa berada dalam kategori "Tidak Berminat". Tidak ada siswa yang masuk dalam kategori "Sangat Berminat" atau "Sangat Tidak Berminat". Rendahnya partisipasi siswa dalam pembelajaran Informatika di kelas khusus olahraga disebabkan oleh tingginya frekuensi absen siswa yang harus mengikuti latihan olahraga dan kebutuhan akan peran guru yang lebih besar dalam mengajar kelas khusus olahraga. Oleh karena itu, diperlukan strategi pengajaran yang lebih interaktif dan relevan dengan minat serta kebutuhan siswa KKO untuk meningkatkan keterlibatan dan minat mereka dalam pembelajaran Informatika. Penelitian ini menyimpulkan bahwa meskipun ada minat yang cukup tinggi terhadap materi APP Inventor, terdapat tantangan yang signifikan dalam menarik minat semua siswa di kelas khusus olahraga, sehingga memerlukan upaya lebih lanjut untuk mengembangkan strategi pengajaran yang efektif.

Abstract

This research examines the learning preferences of F7 phase students at SMAN 4 Surakarta in Informatics, utilizing the Felder-Solomon model. Findings indicate that a large proportion of students (96%) predominantly prefer visual learning, with significant tendencies towards active (74%), sensing (89%), and sequential (59%) learning styles. These results have important implications, suggesting that teachers can devise more effective educational strategies by integrating interactive, visual, and well-structured methods. Moreover, employing varied instructional approaches is essential to cater to the diverse learning styles of students. Gaining a thorough understanding of the students' learning style distribution enables the creation of an optimal learning environment tailored to individual needs and supports the development of strategies that significantly improve student engagement and academic performance.

Abstract

This research aims to analyze and develop strategies that can enhance students' interest and participation in informatics learning on App Inventor subject using mobile devices, with a case study of classroom learning sessions in class of F6 at SMA Negeri 4 Surakarta. The research method used is a qualitative method. Data collection methods in this research include observation, distributing questionnaires to students, and teacher interview. Respondents in this study were a class of F6 students totaling 31 people, consisting of 10 female students and 21 male students. The limitation in this study is that only a small number of students bring laptops to informatics lesson. The results showed that the school's slow internet connection, lack of interest in bringing laptops, lack of skills in using laptops, and the availability of personal laptops were the main challenges to student participation in teaching and learning activities, especially in App Inventor subject. However, using certain strategies such as optimizing the use of mobile devices enables continuous learning inside and outside the classroom.
