Published: July 2022

Student's activities in learning mathematics in elementary schools are suggested to be more in reading, writing, communicating, making pictures, tables, and so on, to encourage problem solving, reasoning, and mathematical connection skills. This activity can be stimulated by giving word problems as mathematical problems that must be solved by students. Giving word problems is the right way when mathematics learning is ready to be accepted by students at the application level in everyday life. To support the strategy of giving word problems to stimulate student learning activity, the CIRC learning model can be applied. CIRC stands for Cooperative Integrated Reading and Composition, is a cooperative learning model that encourages active students to read and write in small groups. Word problems become a support system in learning mathematics by applying the CIRC learning model. By applying the CIRC learning model, students do more reading, writing, communicating, and even arguing and debating in math class. So that students' understanding of mathematics material will be stronger, and students' learning activities and mathematics outcomes will be better.

Pelaksanaan curring beton adalah perawatan beton yang dilakukan setelah beton mengeras. Bertujuan agar beton tidak kehilangan kelembaban terlalu cepat, yang nantinya dapat memicu terjadinya penyusutan pada beton. Jika kelembaban terjadi terlalu cepat, maka beton dapat mengalami penyusutan lebih cepat dan menyebabkan beton mengalami keretakan. Proses pengerasan beton hingga beton tersebut berumur 28 hari, diperlukan adanya perlakuan khusus, yakni perawatan beton. Dalam proses pengerasan beton, terjadi hidrasi semen yang mengakibatkan adanya uap air. Jika beton terlalu cepat kehilangan air, maka beton akan menjadi retak dan tentunya berpengaruh pada kuat tekan akibat retak tersebut. Berdasarkan hal tersebut, dalam penelitian ini dilakukan pembuatan benda uji berupa pelat lantai dengan Panjang 1 meter dan lebar 1 meter dengn tebal pelat lantai 12 cm. Pelat ini dilengkapi dengan besi 15âˆ… "> 8 mm – 150 mm dan perancah. Benda uji dibuat sebanyak 2 buah benda uji, yakni 1 benda uji diperlakukan dengan curring dan 1 benda uji diperlakukan tanpa curring. Mutu beton direncanakan 20 MPa dengan umur beton 28 hari. Curring beton dilakukan selama 7 hari berturut – turut dengan cara menyiram permukaan beton secara continue. Pengujian kuat tekan beton dilakukan setelah beton berumur 28 hari dengan pengujian non destructive test. Pelat lantai dengan yang melewati proses curring beton selama 7 hari berturut turut, menghasilkan kuat tekan maksimum sebesar 23,41 MPa. Pelat lantai yang tidak melewati proses curring beton menghasilkan kuat tekan maksimum sebesar 21,32 MPa. Pelat lantai dengan curring beton meningkatkan kuat tekan beton sebesar 13,46% dibandingkan dengan pelat lantai tanpa curring beton.

Kota Jambi mengalami perkembangan pesat dibidang pembangunan salah satunya pada jalan Kolonel Polisi M. Taher. Di mana terdapat beberapa pusat kegiatan seperti pusat perdagangan elektronik, restoran, dan perkantoran. Yang mana membuat meningkatnya volume lalu lintas sehingga sering terjadi kemacetan pada daerah tersebut yang akan memberikan dampak negatif terhadap lingkungan di sekitar salah satunya berupa emisi gas buang karbon monoksida. Tujuan dari penelitian ini ialah untuk mengetahui pengaruh antara emisi gas buang karbon monoksida (CO) dengan derajat kejenuhan dan kecepatan. Penelitian ini membagi jalan menjadi 2 segmen. Yang mana segmen pertama sepanjang 500 m dan segmen kedua sepanjang 350 m. Metode yang digunakan dalam penelitian ini adalah dengan melakukan survei dan observasi lapangan dengan pengambilan data prilaku lalu lintas antara lain volume lalu lintas, derajat kejenuhan, kecepatan, dan emisi gas karbon monoksida (CO). Dilakukan  selama 3 hari yaitu hari senin, hari kamis dan hari minggu dengan waktu pengambilan data yaitu pada pagi hari pukul 07.00-08.00 WIB, 11.00-12.00 WIB untuk waktu siang, dan 16.00-17.00 WIB untuk waktu sore yang mewakili waktu puncak kegiatan transportasi. Setelah data didapat kemudian dianalisis menggunakan metode analisis regresi dan korelasi untuk melihat pengaruh antara derajat kejenuhan dan kecepatan terhadap emisi gas buang karbon monoksida (CO). Hasil penelitian menunjukkan bahwa pada lokasi volume lalu lintas dan derajat kejenuhan tertinggi terjadi pada hari minggu pukul 11.00-12.00 WIB di segmen 1 yaitu 2163,2 smp/jam dan 0,82. Sedangkan kecepatan terendah dan karbon monoksida tertinggi terjadi pada hari dan waktu yang sama di segmen 1 yaitu 36,12 km/jam dan 2062,96 µg/Nm3. Di mana gas karbon monoksida (CO) pada lokasi masih di bawah baku mutu udara ambien sehingga masih dalam kategori aman. Pengaruh prilaku lalu lintas terhadap emisi gas buang karbon monoksida (CO) menunjukkan semakin meningkatnya volume lalu lintas dan derajat kejenuhan, semakin tinggi gas karbon monoksida (CO) yang dihasilkan sedangkan semakin meningkatnya kecepatan kendaraan, semakin rendah gas karbon monoksida (CO) yang dihasilkan.

Pada program Dana Desa telah disediakan fasilitator pendamping yang dimulai dari pendampingan tingkat desa, kecamatan, kabupaten dan tingkat provinsi. Fasilitator dalam desa yang biasa disebut dengan fasilitator local desa mendampingi tim pengelola kegiatan dan perangkat desa dalam pengelolaan administrasi dan teknis di tingkat desa. Apalagi di bidang Pembangunan. Dahulu, untuk Pembangunan Infrastruktur baik, Cor Rabat Beton, Talud maupun Drainase, penyusunan RAB dan Gambar di serahkan ke Pihak ke tiga atau Faskel. Namun untuk era sekarang ini Perangkat Desa di tuntut untuk bisa membuat dan menyusun Design Gambar, dan RAB, dan segala hal penyusunnya, sehingga sesuai dengan kaidah ilmu Teknik sipil, agar masyarakat desa bisa mandiri dalam membangun infrastruktur dengan murah dan efisien. Dalam penelitian ini tujuan yang ingin disampaikan oleh penulis yaitu untuk mengetahui kemampuan pemerintah Desa dalam penyusunan Desain Anggaran Biaya Infrastruktur Pedesaan di Kecamatan Air Hangat Timur Kabupaten Kerinci. Setelah dilakukannya penelitian di Kecamatan Air Hangat Timur Kabupaten Kerinci di dapat kan hasil dimana kemampuan pemerintah desa dalam penyusunan desain anggaran infrastruktur masih tergolong dalam kategori rendah, hal tersebut di dapat dilihat dari jumlah responden dalam skor pengkategorian kemampuan lebih dominan pada kategori rendah yaitu sebanyak 18 responden untuk kategori rendah, 17 responden untuk kategori sedang, dan 15 responden untuk kategori tinggi. Hal ini sejalan juga dengan pernyataan Notoatmodjo (2012) bahwasannya terdapat 6 tingkatan pengetahuan yang dicakup dalam domain kognitif yaitu Mengetahui (know), Memahami (comprehension), Aplikasi (application), Analisis, Sintesis, Evaluasi. Dalam penelitian ini sendiri terjawab bahwasannya tingkat pengetahuan yang dominan menjadi kendala dalam kemampuan pemerintah desa dalam penyusunan desain anggaran infrastruktur pedesaan di kecamatan Air Hangat Timur Kabupaten Kerinci yaitu pada tingkat mengetahui (know) dan memahami (comprehension), hal tersebut dibuktikan dengan kurang tau dan pemahaman tentang desain anggaran oleh perangkat desa sedangkan untuk aplikasi, analisis, sintesis, dan evaluasi sudah berjalan baik sesuai dengan ketentuan dimana sudah di atur oleh faskel atau pihak ketiga dari desa tersebut.

PI3K inhibitors in chronic lymphocytic leukemia: where do we go from here?
Authors: Skanland Sigrid S. , Brown Jennifer R.
Published: July 2022

Phosphatidylinositol 3-kinase (PI3K) inhibitors are effective in chronic lymphocytic leukemia (CLL). However, the severe toxicity profile associated with the first-generation inhibitors idelalisib and duvelisib, combined with the availability of other more tolerable agents, have limited their use. CLL is still considered incurable, and relapse after treatment, development of resistance, and treatment intolerance are common. It is therefore of interest to optimize the administration of currently approved PI3K inhibitors and to develop next-generation agents to improve tolerability, so that this class of agents will be considered an effective and safe treatment option when needed. These efforts are reflected in the large number of emerging clinical trials with PI3K inhibitors in CLL. Current strategies to overcome treatment limitations include intermittent dosing, which is established for copanlisib and zandelisib and under investigation for duvelisib and parsaclisib. A second strategy is to combine the PI3K inhibitor with another novel agent, either as a continuous regimen or a fixedduration regimen, to deepen responses. In addition to these approaches, it is of interest to identify higher-resolution actionable biomarkers that can predict treatment responses and toxicity, and inform personalized treatment decisions. Here, we discuss the current status of PI3K inhibitors in CLL, factors limiting the use of currently approved PI3K inhibitors in CLL, current strategies to overcome these limitations, and where to go next.
