Analisis Pengaruh Perubahan Penutup Lahan Terhadap Sebaran Suhu Permukaan di Kota Batu Pada Tahun 2002 Dan 2017

This research is trying to observe land cover and temperature changes in batu 2002 up to 2017. its provide data to analyst the effect of land cover changes to distribution of Land Surface Temperature in Batu City. This research used Landsat 7 data recorded in 2002 and Landsat 8 data recorded in 2017. Sample of landcovers are dermine by purposive sampling method. This research utilize SCP Plugin (Semi automatic Classification Plugin) in Quantum GIS application to do a supervised multispectral classification in a SAM (Spectral Angled Mapping) logarithm form to produce a data in a form of land cover. The temperature data obtained by integrating the number of emissivity from a land cover with spectral value in Landsat image thermal band. Those data are analysed by its spatial distribution to determine wheter landcover can effect the land surface temperature. The land cover is a vegetation. The area of this land cover vegetation has expanded from 13456 Ha in 2002 to 13687.1 Ha with 231.1 Ha area expansion in 2017. The Bare land cover has narrowed for 1344.9 Ha, this number has drastically decreased from the previous year. 5684 Ha land cover area in 2002 is narrowed into 4303.1 Ha in 2017. Build-up Area covers 906.2 Ha in 2002 is expanded to 2020 Ha in 2017. It has 1113.8 Ha expansion, greater from the previous year. The change of surface temperature is tend to be hotter in 2002 and it tend to be cooler in 2017. It isl because the physical change of the land cover and the El-Nino phenomenon.

Pemanfaatan Limbah Padat Bulu Ayam pada Usaha Home Industry Rumah Pemotongan Ayam menjadi Kerajinan Tangan

Pengamatan ini bertujuan untuk mengetahui limbah yang ada di rumah ayam potong dan melakukan pemanfaatan limbah padat menjadi kerajinan tangan. Pada usaha ayam potong ini belum sepenuhnya menerapkan konsep efisiensi lingkungan. Masih banyak limbah yang dibuang begitu saja tanpa berpikir panjang dampak yang ditimbulkan. Limbah yang tidak didaur ulang kembali akan berdampak pada pencemaran air, udara, dan tanah Limbah yang ditemukan pada usaha ayam potong tersebut meliputi limbah air dan limbah padat. Limbah yang dihasilkan dari limbah air adalah air hasil pencucian ayam. Sementara limbah padat yang dihasilkan adalah unggas yang sudah mati, organ dalam ayam, bulu-bulu ayam yang dibuang ke kali, dan kotoran ayam. Pelaksaaan dalam pengamatan kali ini dengan melakukan studi pustaka, Melakukan observasi langsung, Pengambilan sampel atau bahan yang akan diolah, Melakukan edukasi kepada pemilik dan karyawan, Melakukan pengolahan atau daur ulang pada limbah padat yang akan didaur ulang menjadi kerajinan tangan. Harus ada kesadaran dari pelaku usaha dan karyawan untuk menerapkan prinsip manufaktur hijau dan akan pentingnya kesehatan serta dampak yang ditimbulkan bagi masyarakat sekitar dan melaksanakan sebuah proses daur ulang pada limbah padat yang ditemukan atau memanfaatkan teknologi proses yang efektif yang memungkinkan produksi bahan baku untuk sektor lain sekaligus mengurangi jumlah limbah yang dihasilkan

Analysis of risks of gastric cancer by gastric mucosa among Indonesian ethnic groups

Indonesia is a big country with multiethnic populations whose gastric cancer risks have not been elucidated. We performed a nationwide survey and obtained histological specimens from 1053 individuals in 19 cities across the country. We examined the gastric mucosa, the topography, the atrophic gastritis risk factors, and the gastric cancer risk scores. Almost half (46.1%) of the patients with dyspeptic symptoms had histological abnormalities; chronic (36.3%) and atrophic gastritis (28.9%) being the most frequent. Individuals of the Timor ethnicity had the highest prevalence of acute (52.6%) and chronic gastritis (68.4%), even those negative for H. pylori. Our topographic analysis showed the majority of patients had predominantly antral acute and chronic gastritis. A multivariate logistic regression model showed age (Odds ratio [OR], 1.107), Timor ethnicity (OR, 8.531), and H. pylori infection (OR, 22.643) as independent risk factors for presence of atrophic gastritis. In addition, the gastric cancer risk score was highest in those from Timor, Papuan, and Bugis ethnic populations. Overall, Indonesia is a low-risk gastric cancer country. However, several ethnic groups displayed severe gastric mucosa symptoms suggesting policy makers should focus on those ethnic groups to perform gastric cancer screenings and to eradicate H. pylori

Relevansi Kurikulum Merdeka Belajar dengan Model Pembelajaran Abad 21 dalam Perkembangan Era Society 5.0

Society 5.0 adalah masyarakat yang dapat menyelesaikan berbagai tantangan dan permasalahan sosial dengan memanfaatkan berbagai inovasi yang lahir di era Revolusi industri 4.0 seperti Internet on Things (internet untuk segala sesuatu), Artificial Intelligence (kecerdasan buatan), Big Data (data dalam jumlah besar), dan robot untuk meningkatkan kualitas hidup manusia. Era ini menjadi peluang sekaligus tantangan baru bagi siswa untuk meningkatkan soft skill sebagai persiapan di masa yang akan datang. Telah diketahui secara bersama bahwa kurikulum merupakan “nyawa” dalam pendidikan. Kurikulum hendaknya perlu dievaluasi secara dinamis dan berkala mengikuti perkembangan zaman terutama IPTEK. Kurikulum juga disusun dengan memperhatikan kompetensi yang dibutuhkan oleh masyarakat dan lulusan. Kurikulum Merdeka Belajar merupakan salah satu kebijakan baru Kementerian Pendidikan, Kebudayaan, Riset, dan Teknologi Republik Indonesia (Kemendikbud Ristek RI) yang ditujukan untuk mewujudkan proses pembelajaran yang inovatif dan mengikuti kebutuhan siswa (student-centered). Era Society 5.0 berlangsung pada Abad 21 yang dimana merupakan kejayaan dunia digital. Model pembelajaran abad ke-21 juga menuntut siswa untuk mencapai keterampilan 4C yaitu critical thinking, communication, colaboration, and creativity. Penelitian ini menggunakan metode kualitatif deskriptif. Hasil penelitian ini didapat dari kajian beberapa literatur. Hasilnya menjelaskan bagaimana relevansi kurikulum merdeka belajar dengan model pembelajaran abad ke 21 di perkembangan era society 5.0

CYP2C19 Polymorphisms in Indonesia: Comparison among Ethnicities and the Association with Clinical Outcomes

CYP2C19 polymorphisms are important factors for proton pump inhibitor-based therapy. We examined the CYP2C19 genotypes and analyzed the distribution among ethnicities and clinical outcomes in Indonesia. We employed the polymerase chain reaction-restriction fragment length polymorphism method to determine the CYP2C19 genotypes and evaluated inflammation severity with the updated Sydney system. For CYP2C19*2, 46.4% were the homozygous wild-type allele, 14.5% were the homozygous mutated allele, and 39.2% were the heterozygous allele. For CYP2C19*3, 88.6% were the homozygous wild-type allele, 2.4% were the homozygous mutated allele, and 9.0% were the heterozygous allele. Overall, the prevalence of rapid, intermediate, and poor metabolizers in Indonesia was 38.5, 41.6, and 19.9%, respectively. In the poor metabolizer group, the frequency of allele *2 (78.8%) was higher than the frequency of allele *3 (21.2%). The Papuan had a significantly higher likelihood of possessing poor metabolizers than the Balinese (OR 11.0; P = 0.002). The prevalence of poor metabolizers was lower compared with the rapid and intermediate metabolizers among patients with gastritis and gastroesophageal reflux disease. Intermediate metabolizers had the highest prevalence, followed by rapid metabolizers and poor metabolizers. Dosage adjustment should therefore be considered when administering proton pump inhibitor-based therapy in Indonesia

Helicobacter pylori Prevalence in Indonesia West and East Region

   Helicobacter pylori (H. pylori) infection status in Indonesia might be higher than the actual prevalence. A comprehensive epidemiologic study is necessary to explore infection susceptibility by demographic characteristics, especially between Indonesia’s Eastern and Western regions. We present data related epidemiology H. pylori infection and risk factor for it </p
