Abstract

Persekongkolan tender merupakan cerita lama yang sampai sekarang masih saja terjadi. Iklim persaingan usaha yang tidak sehat merupakan akar dari permasalahan ini, untuk itu diperlukannya instrumen hukum dan lembaga pengawas persaingan usaha. Di Indonesia terdapat Undang-Undang Nomor 5 Tahun 1999 dan sebagai lembaganya adalah Komisi Pengawas Persaingan Usaha (KPPU). Saat ini persekongkolan tender bukan hanya melanggar pasal-pasal yang ada di Undang-Undang Nomor 5 Tahun 1999 namun dewasa ini sudah menjalar pada tindak pidana korupsi.

Abstract

Kesehatan anak-anak merupakan faktor yang penting untuk meningkaatkan kecerdasan bangsa, untuk memenuhi kebutuhan tersebut maka salah satunya dengan menerapkan Senam Anak Indonesia sebagai kegiatan rutin setiap pagi.Kecepatan dan kelincahan merupakan faktor pendukung yang utama dalam melakukan gerakan senam, Hal itu juga yang menjadikan kegiatan senam baik dilakukan oleh semua kalangan usia mulai dari anak-anak, dewasa hingga orang tua.Senam merupakan gerakan olahraga yang diiringi dengan musik atau lagu khusus pengiring senamnya. Pada umumnya sebagian besar orang sangat antusias mengikuti kegiatan ini terutama anak-anak.Hasil penelitian menggunaka SPSS,dan hasilnya menunjukan bahwa rata-rata kecepatan adalah 7,57 dengan nilai minimum 6,49,nilai maximum 8,3, dan standart deviasi 0,52.Rata-rata kelincahan adalah 17,6 dengan nilai minimum 16,13, nilai maximum 18,9, dan standart deviasi 1,07,maka bahwa besarnya nilai signifikansi kecepatan adalah0,933 >taraf kesalahan 0,05, sehingga dinyatakan berdistribusi normal.Besarnya besarnya nilai signifikansi kelincahanadalah 0,880 >taraf kesalahan 0,05, sehingga dinyatakan berdistribusi normal.Maka ada hasil hubungan kelincaha dan kecepatan

Abstract

Latar belakang : Skin graft saat ini menjadi salah satu terapi pilihan pada proses penyembuhan luka yang selalu berkembang. Proses epitelisasi dan pembentukan pembuluh darah baru memiliki peran penting dalam penyembuhan luka skin graft. Kandungan kafein (1,3,7 trimethylxanthine) sebagai antioksidan memiliki peran yang penting dalam penyembuhan luka. Tujuan dari penelitian ini adalah membuktikan efek kafein dalam berbagai dosis dalam meningkatkan densitas mikrovaskuler dan epitelisasi pada luka skin graft.Metode : Penelitan ini adalah studi eksperimental dengan “Blinded randomized post test only controlled group design” terhadap 24 ekor tikus Sprague Dawley dilakukan skin graft autologous pada waktu yang bersamaan. Sampel dibagi secara acak menjadi 4 grup (K = tanpa pemberian kafein), (P1= Kafein 3 mg), (P2 = Kafein 6 mg), (P3 = Kafein 9 mg).Penilaian prosentase epitelisasi dan jumlah densitas mikrovaskuler jaringan dilakukan dengan pengecatan hematoxylin & eosin setelah hari ke 7 pasca skin graft.Hasil : Analisis statistik perbandingan prosentase epitelisasi jaringan didapatkan didapatkan perbedaan yang bermakna antara kelompok kelompok K vs PI ( p = 0,003 ), K vs P2 (p = 0,001), K vsP3 (p = 0,001), P1 vs P2 (p = 0,001), P1 vs P3 (p = 0,001). Perbedaan yang tidak bermakna didapatkan antara kelompok P2 vs P3 (p = 0,669) dan pada jumlah densitas mikrovaskuler, didapatkan perbedaan yang bermakna antara kelompok K vs P2 (p = 0,010), K vs P3 (p = 0,008), P1 vs P2 (p = 0,009), P1 vs P3 (p = 0,007), P2 vs P3 (p = 0,008). Perbedaan yang tidak bermakna didapatkan antara kelompok K vs P1 (p = 0,343).Kesimpulan :Kafeindapat meningkatkanprosentase epitelisasi dan jumlah densitas mikrovaskuler jaringan pada proses penyembuhan luka skin graft autologus tikus Sprague Dawley.Kata Kunci : Kafein, skin graft autologus, epitelisasi, densitas mikrovaskuler ABSTRACTTitle: Effects of Increased Dose Caffeine on Epithelialization and Microvascular Density in the Healing of Full Thickness Skin Graft Autologous Sprague Dawley Mouse Background: Skin graft is currently one of the therapies of choice in the healing process of wounds that always develops. The process of epithelialization and formation of new blood vessels has an important role in healing skin graft wounds. Caffeine content (1,3,7 trimethylxanthine) as an antioxidant has an important role in wound healing. The aim of this study is to prove the effects of caffeine in various doses in increasing microvascular density and epithelialization in skin graft injuries.Method: This research is an experimental study with a "Blinded randomized post test only controlled group design" of 24 Sprague Dawley rats by autologous skin graft at the same time. Samples were randomly divided into 4 groups (K = no caffeine), (P1 = Caffeine 3 mg), (P2 = Caffeine 6 mg), (P3 = Caffeine 9 mg). The assessment of the percentage of epithelialization and the amount of tissue microvascular density was done by painting hematoxylin & eosin after 7 days after skin graft.Results: Statistical analysis of the comparison of tissue epithelialization percentage found significant differences between groups K vs PI (p = 0.003), K vs P2 (p = 0.001), K vsP3 (p = 0.001), P1 vs P2 (p = 0.001) , P1 vs P3 (p = 0.001). No significant difference was found between the P2 vs P3 group (p = 0.669) and in the total microvascular density, a significant difference was found between the K vs P2 group (p = 0.010), K vs P3 (p = 0.008), P1 vs P2 (p = 0.009), P1 vs P3 (p = 0.007), P2 vs P3 (p = 0.008). No significant difference was found between the K vs P1 groups (p = 0.343).Conclusion: Caffeine can increase the percentage of epithelialization and the amount of tissue microvascular density in the healing process of autologous skin grafts of Sprague Dawley rats.Keywords: Caffeine, autologous skin graft, epithelialization, microvascular density

Abstract

This study aims to develop Hawgent Dynamic Mathematics Software Learning Media. The broad material of ICT-based kites as a medium for learning mathematics for grade IV SD students. The research method used in this research is Research and Development (R and D) with a 4-D model. The results of the material expert’s assessment of the six components include: the language aspect is 70%, the ease of use of learning media reaches the highest average of 90%, and it is concluded that the overall average percentage is 83.33%. It can be said that the ICT-based learning media that have been designed are in the feasible category. While the results of the material expert’s assessment of the four aspects obtained an average percentage of 87.89%. Based on the results of the study Hawgent Dynamic Mathematics Software Learning Media can be used as a learning media for learning mathematics to find the area ofa kite.

Abstract

Now, the whole world is facing the coronavirus pandemic. In the meantime, students in China are required to do social distancing and not go to school. This coronavirus pandemic resulted in the use of online learning to teach students. In this research, we will get to know the students’ learning attitude towards online learning during the coronavirus pandemic. The sample population for this research are students in West Java, Indonesia. The data will be collected by using questionnaires and there was a total of 16 questionnaires that is collected for this research. The result of this research shows that online learning during this coronavirus pandemic is not very effective. Also, the students’ learning interest towards online learning is also very low. Based on the interview done on students and teachers, most of them stated that there are various factors that can affect online learning in China such as learning environment, internet and etc. The suggestion that is given in this research is that aside from online classes, teachers can also use video learning media that are used by developed countries so that it can solve the bad internet problem. The result of this research hopefully, can become a reference to improving a more effective learning media that can be used during the coronavirus pandemic in Indonesia.
