Alpian E, Ardiansyah RS, Wulandari NF, Ichsan MH, Putri K, Arsi A. 2021. Attack intensity of Spodoptera frugiperda in the vegetative phase of maize (Zea mays) in Sumatera Selatan. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang  20 Oktober 2021. pp. 537-544.  Palembang: Penerbit dan Percetakan Universitas Sriwijaya (UNSRI). Spodoptera frugiperda is a pest that attack corn plant which is the most destructive pest in corn cultivation in the vegetative phase, this problem caused losses to the corn farmer sector and reduces the economic side of corn farmers.  This study aimed to determine the intensity of the attack of S. frugiperda larvae in the vegetative phase of maize.  This research methodology refers to the literature study of several journal articles.  S. frugiperda attack maize in the vegetative phase, That cause stunted growth.  Symptoms of the attack caused by S. frugiperda are the presence of holes and dirt that resembles sawdust.  The level of damage from S. frugiperda is said to be high in the vegetative phase and will decrease with age.  It is said to be high because the larvae of S. frugiperda attack the growing point of corn plants and cause damage to the young shoots.

Abstract

Tujuan utamanya adalah untuk meningkatkan kesehatan mental siswa kelas 2 Sekolah Dasar dalam mata pelajaran pendidikan jasmani dan kesehatan. Di era perkembangan teknologi informasi dan kecerdasan buatan, muncul peluang besar untuk menciptakan sistem yang mampu memantau dan mendeteksi emosi anak secara real-time, sehingga memberikan dukungan emosional yang lebih akurat dan tepat sasaran dalam konteks pendidikan. Pendekatan literature review untuk menganalisis teori-teori terkait deteksi emosi, pengolahan citra wajah, dan penerapan EML dalam dunia pendidikan. Dari hasil kajian pustaka, EMOKIDS diharapkan dapat mengenali emosi dasar siswa, seperti bahagia, marah, takut, dan cemas, yang memiliki pengaruh langsung terhadap keterlibatan mereka dalam aktivitas pendidikan jasmani. Analisis menunjukkan bahwa pemantauan emosi melalui ekspresi wajah dapat menciptakan lingkungan belajar yang lebih inklusif. Hal ini mempermudah guru dalam memberikan intervensi yang sesuai berdasarkan kondisi emosional siswa, terutama pada siswa yang menghadapi tantangan emosional selama proses pembelajaran.Penggunaan teknologi EML dalam pengolahan data menjadi salah satu keunggulan utama alat ini. Dengan mendeteksi emosi anak secara efektif, EMOKIDS diharapkan dapat menjadi alat yang mendukung peningkatan kesehatan mental siswa. Teknologi ini memungkinkan guru untuk memahami lebih baik kebutuhan emosional siswa dan memberikan pendekatan pengajaran yang lebih personal dan sesuai. Alat ini juga berpotensi meningkatkan partisipasi siswa dalam pembelajaran, khususnya pada pendidikan jasmani, di mana tantangan fisik dan sosial dapat memengaruhi motivasi dan kenyamanan siswa

Abstract

The aim of this research is to determine the improvement in mathematics learning outcomes of class This type of research is PTK which is carried out in two cycles. The subjects in this research were 31 students in class XI MIPA at R.A Kartini Private High School, Tebing Tinggi City. The instruments in this research consisted of tests and observation sheets. The results of data analysis in cycle I obtained an average class percentage of 74.51% and experienced an increase in cycle II, namely obtaining an average class percentage of 85.80%. And the results of the classical completeness analysis in cycle I got a percentage of 70.97%, namely there were 22 students who had reached the KKM, then classical completeness in cycle II got a percentage of 87.09%, namely there were 27 students who had reached the KKM. From this data, it can be seen that there was an increase in diagnostic tests, cycle I tests, and cycle II tests. The observation results indicate that the learning process using the Two Stay Two Stray type cooperative learning model is classified in the good category with a score of 3.31. Based on these data, the indicators for this research have been fulfilled. It was concluded that the application of the Two Stay Two Stray type cooperative learning model could improve the mathematics learning outcomes of class XI MIPA students at R.A Kartini Private High School, Tebing Tinggi City.
