Buildings consume about 40% of the world's energy, beginning from the process of making the building itself to how the building could meet human thermal comfort needs. In the past, reeds were often used in traditional buildings, but unfortunately these days the practice is being abandoned. Several studies have shown that weeds can reduce building temperatures. However, these studies research has not examined how reeds are used as insulation material along with bricks so the purpose of this study is to compare the thermal insulation performance between plain brick and brick wall with the addition of reed insulation. The method used in this research is to use Ecotect simulation. Based on the results of simulations carried out it is known that model 1, namely the plain brick wall, has an outside-inside temperature difference of -1.32917 ° C. This means that the average temperature inside is hotter than the outside temperature by 1.32917 ° C. Meanwhile in model 2, the brick wall with the addition of reeds insulation has an outside-inside temperature difference of 0.445833 ° C. This means that the average temperature inside is cooler than the outside temperature by 0.445833 ° C. Therefore, it can be concluded that reeds could be used as thermal insulation material because it could store heat better than the material in Model 1, which is a plain brick wall.

Pembelajaran daring yang dilakukan pada saat pandemi mengharuskan guru untuk menggunakan media pembelajaran agar dapat menunjang pembelajaran di sekolah maupun di kelas. Berdasarkan observasi yang dilakukan dalam pembelajaran yang dilakukan berbantuan Google meet  di SMA Negeri 1 Kabila memiliki kendala kurangnya penggunaan media pembelajaran yang digunakan dalam menunjang materi yang diajarkan khusunya dalam materi fisika yang semestinya menggunakan laboratorium untuk siswa bisa memahami. Penelitian ini bertujuan untuk mengetahui pengaruh integrasi virtual laboratorium fisika berbasis simulasi PhET dengan model discovery learning terhadap hasil belajar siswa pada ranah kognitif C3 dan C5. Jenis penelitian ini adalah quasi eksperiment dengan populasi seluruh kelas XI IPA di SMA Negeri 1 Kabila berjumlah 6 kelas. Sampel pada penelitian ini ditentukan dengan non-probability sampling  yaitu tidak  menggunakan keseluruhan populasi untuk menjadi sampel, jadi sampel pada penelitian ini sebanyak 23 orang siswa. Instrumen penelitian yang digunakan adalah instrument tes dalam bentuk soal uraian atau essay. Soal essay yang diberikan melalui pretest dan posttest yang berjumlah 10 nomor yang telah dinyatakan valid oleh validator. Setelah data penelitian diperoleh menggunakan data pretest dan posttest, uji t-test, n-gain normalisasi membuktikan bahwa kemampuan peserta didik mampu menerapkan simulasi PhET dalam pembelajaran fisika serta mampu memanfaatkan simulasi PhET dengan model discovery learning ini sebagai pengetahuan baru dalam pembelajaran fisika.

Indonesia is a maritime country with great potential, in various aspects of living natural resources and human resources. Not many people know that Gorontalo is a province that has amazing coastal tourism objects. Since becoming a province, Gorontalo has explored a lot of potential so that it can compete ahead with other provinces, especially in the field of natural tourism. Talking about the potential for natural tourism, in Gorontalo Province, especially Molosipat Village, Pohuwato Regency has several coastal areas with beautiful natural potential so that it is very suitable to be used as a beach tourism spot. The large number of natural potentials in Molosipat village is not followed by a good arrangement of the tourist area so that the natural potential is simply lost to tourists. In connection with these conditions, the focus in the implementation of this service is to provide socialization and training to the community of Molosipat village related to how to organize natural tourism in empowering the natural potential of the coast which is owned by the Molosipat coastal area. This activity is carried out by providing socialization and training which includes: discourse, discussions and structuring the Molosipat beach tourism area. The targets that will be involved in this activity are the Molosipat community, especially those in the Molosipat beach hamlet, youth organizations and Molosipat village officials. The implementation of the "Kuliah Kerja Nyata (KKN) Tematik" service activity held in Molosipat Village, Popayato Barat Subdistrict, Pohuwato Regency has been running according to the initial plan, but in the process of implementing it still needs to be done regularly in training and mentoring because this will be useful in developing structuring beach tourism area in the village of Molosipat. Therefore, the form of community service activities in terms of socialization and training on structuring coastal tourism areas to empower the natural potential of the coast should be continued continuously.

Hotel adalah salah satu solusi untuk tempat sementara bagi seseorang / kelompok untuk tinggal selama mereka melakukan kebutuhan mereka di daerah / kota. Penyediaan fasilitas pendukung diminimalisir dan disesuaikan dengan kebutuhan kelas hotel yang akan dipilih. Dalam desain, desainer umumnya lebih mementingkan fungsionalitas daripada kualitas pencahayaan. Kualitas cahaya yang kurang baik akan mempengaruhi suasana ruangan sehingga menimbulkan tekanan psikologis pada penggunanya dan gangguan penglihatan yang berdampak pada kesehatan. Tujuan penelitian adalah menganalisis sistem pencahayaan pada kamar hotel dengan mengambil standar dasar pedoman teknis SNI di bidang pencahayaan, yaitu SNI 6197:2011 tentang Konservasi Energi sistem pencahayaan pada bangunan gedung, dan SNI 03-6575-2001 tentang tata cara perancangan sistem pencahayaan buatan. pada bangunan. Simulasi menggunakan perangkat lunak DIALux 9.0 open source, yang merupakan perangkat lunak simulasi untuk menghitung kebutuhan pencahayaan. Hasil analisis menunjukkan bahwa kondisi pencahayaan pada kamar hotel standar di hotel tidak memenuhi standar SNI, sehingga perlu dilakukan beberapa cara untuk mengoptimalkan tingkat pencahayaan.
