Guru telah dikenal luas sebagai salah satu faktor penting yang mempengaruhi prestasi belajar siswa. Kompetensi guru, khususnya pengetahuannya, membantu guru untuk mengorganisasi­kan pem­belajaran yang efektif guna memfasilitasi keberhasilan belajar siswa. Salah satu jenis penge­tahuan yang penting dikuasai oleh guru adalah Pedagogical Content Knowledge (PCK). PCK merupakan kombinasi pengetahuan konten dan pedagogi yang mengarah pada bagaimana aspek-aspek tertentu dari materi pembelajaran diatur, diadaptasi, dan direpresentasikan untuk diterapkan di dalam proses pembelajaran. Penelitian ini bertujuan untuk mendeskripsikan ting­kat PCK guru matematika dan prestasi belajar siswa, serta menguji hubungan keduanya. Pene­litian ini adalah kuantitatif-korelasional dengan subjek penelitian 56 guru mate­matika dan 499 siswa SMP di Kabupaten Manggarai, Nusa Tenggara Timur. Data PCK guru dan prestasi siswa dikumpulkan menggunakan tes objektif yang telah dinyatakan valid dan reliabel. Data dianalisis menggunakan statistik deskriptif dan inferensial. Hasil penelitian mengungkapkan bahwa seba­gian besar guru memiliki PCK pada kategori rendah dan sebagian besar siswa memiliki prestasi belajar pada kategori rendah. Namun demikian, terdapat korelasi positif yang signifikan antara PCK guru mate­matika dan prestasi belajar siswa dengan kontribusi PCK guru terhadap prestasi belajar siswa sebesar 16,1%. Relationship between pedagogical content knowledge of mathematics teacher and learning achievement of junior high school studentsAbstractTeachers’ competence, especially their knowledge, helps them organize effective classrooms to facilitate students’ success. One of the essential knowledge that should be mastered by a teacher is Pedagogical Content Knowledge (PCK).

Published: March 2021

Background
Screening patients for eligibility for clinical trials is labor intensive. It requires abstraction of data elements from multiple components of the longitudinal health record and matching them to inclusion and exclusion criteria for each trial. Artificial intelligence (AI) systems have been developed to improve the efficiency and accuracy of this process.

Objective
This study aims to evaluate the ability of an AI clinical decision support system (CDSS) to identify eligible patients for a set of clinical trials.

Methods
This study included the deidentified data from a cohort of patients with breast cancer seen at the medical oncology clinic of an academic medical center between May and July 2017 and assessed patient eligibility for 4 breast cancer clinical trials. CDSS eligibility screening performance was validated against manual screening. Accuracy, sensitivity, specificity, positive predictive value, and negative predictive value for eligibility determinations were calculated. Disagreements between manual screeners and the CDSS were examined to identify sources of discrepancies. Interrater reliability between manual reviewers was analyzed using Cohen (pairwise) and Fleiss (three-way) κ, and the significance of differences was determined by Wilcoxon signed-rank test.

Results
In total, 318 patients with breast cancer were included. Interrater reliability for manual screening ranged from 0.60-0.77, indicating substantial agreement. The overall accuracy of breast cancer trial eligibility determinations by the CDSS was 87.6%. CDSS sensitivity was 81.1% and specificity was 89%.

Conclusions
The AI CDSS in this study demonstrated accuracy, sensitivity, and specificity of greater than 80% in determining the eligibility of patients for breast cancer clinical trials. CDSSs can accurately exclude ineligible patients for clinical trials and offer the potential to increase screening efficiency and accuracy. Additional research is needed to explore whether increased efficiency in screening and trial matching translates to improvements in trial enrollment, accruals, feasibility assessments, and cost.

<div><p>Este artigo tem por objetivo apresentar uma análise do cenário de crises, disputas e resistências que envolve as comunidades tradicionais pesqueiras e quilombolas da Ilha de Maré, Salvador – Bahia. Uma das temáticas que tem ganhado relevante destaque, nas últimas décadas, refere-se às inúmeras disputas e conflitos territoriais que as comunidades tradicionais pesqueiras têm vivenciado nos seus territórios. No estado da Bahia esse cenário envolve cerca de 600 comunidades e mais de 100 mil famílias, dentre as quais destacamos aquelas situadas na Ilha de Maré, localizada na Baía de Todos os Santos (BTS). Possuidoras de um amplo conhecimento sobre as águas, os manguezais e os pescados da BTS, a relação de apropriação desenvolvida por essas comunidades com a natureza é caracterizada por extremos laços de identidade, pertencimento e, principalmente, respeito, onde são desenvolvidos valores simbólicos e materiais que asseguram o seu modo de vida e configuram suas territorialidades. Territorialidades que têm sido intensamente ameaçadas e, em alguns casos, destruídas, pelo modelo de desenvolvimento historicamente empregado no local. Observa-se que os espaços que eram de uso das comunidades, aos poucos, foram sendo ocupados, delimitados e controlados por novas e distintas atividades (aquícola, portuária, metalúrgica, petroquímica, turística etc.), originando inúmeras crises sociais, econômicas, ambientais, além das disputas territoriais. Para o desenvolvimento da análise, recorremos metodologicamente às técnicas da pesquisa participante com a utilização dos seguintes instrumentos: levantamento bibliográfico, documental e, principalmente, de campo, com a realização de reuniões, participação em audiências públicas, oficinas de geografia e cartografia, mapeamento e georreferenciamento dos territórios em disputa.</p></div><p> </p>
Analysis of cross-sectional area of digester on biogas production rate
Authors: Tira H.S. , Padang Y.A. , Sukrenewita I.K. 
Published: March 2021

Biogas has become one of the promising alternative fuels. This is triggered by relative ease of production while on the other hand the raw material is cheap and easy to be obtained. In order to get higher biogas production rate, a work has been done with digester cross-sectional area modification. Under the modification an improvement in biogas yield was obtained. The research also has opened up new outlook to set up a better digester design for maximum biogas production. The experimental results showed that a higher biogas volume yield was obtained in larger cross-sectional area compared to that of smaller one. Increasing the cross-sectional area twice will benefit at least three times in terms of biogas volume produced under similar raw material input volume. A wide-open cross-section surface is a major factor for good breeding of microbial to produce methane. Under the condition, microbes experience less pressure due to the evenly distributed volume of the substrate which resulted in a comfortable environment for bacteria.
