Abstract

Penelitian ini dilakukkan untuk mengukur efisiensi pupuk urea yang dilapisi arang aktif terhadap produktivitas kualitas tanaman. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuaan yaitu P1=0% (tanpapelapis arang aktif), P2= 10%, P3= 20% dan P4=30% dari jumlah urea yang diberikan. Ulangan dalam penelitian ini berjumlah 15 yang terbagi dalam 3 kelompok pemberian urea yaitu, K1= 5gr/tanaman, K2= 10gr/tanaman dan K3=20 gr/tanaman, sehingga total unit perlakuan adalah 60. Parameter yang diamati yang diamati pada penelitian ini adalah Pengukuran tinggi tanaman , lingkar batang sebagai indikator efisiensi pertumbuhan tanaman rumput gajah. Penelitian ini dilaksanakan selama 3 bulan dengan masa penanam 42 hari.Hasil dari penelitian ini adalah perlakuan pelapisan 5%, 10%, 20% dan 30% tidak berpengaruh nyata terhadap produksi bahan segar, tinggi dan lingkar batang tanaman. Akan tetapi berpengaruh nyata pada kadar Bahan kering dan Bahan Organik tanaman. Kadar BK dan BO yang paling tinggi adalah pada perlakuan P3 (20%). Semua kelompok yaitu K1(urea 5 gr), K2 (10 gr) dan K3 (20 gr) tidak berpengaruh nyata pada semua parameter yang diamati yaitu produksi bahan segar, bahan kering, bahan organik, tinggi dan lingkar batang.

Abstract

Tujuan: Menilai pengaruh kateterisasi urin, colok vagina dan keluarnya feses saat mengedan pada pertolongan persalinan spontan terhadap kejadian infeksi saluran kemih. Tempat: Bagian Kebidanan dan Kandungan Universitas Sriwijaya, Rumah Sakit Umum Mohammad Hoesin, Palembang - Indonesia. Bahan dan cara kerja: Penelitian ini merupakan cross sectional study. 100 orang penderita yang partus spontan diambil secara consecutive sampling. Dilakukan pengisian kuesioner yang memasukkan data mengenai berapa kali kateterisasi dan colok vagina dilakukan, apakah ada kontaminasi feses pada kala II, dan urin diambil menggunakan kateter steril pada mid stream. Urin lalu diperiksa dengan strip nitrit urin. Hasil: Dari hasil penelitian didapatkan bahwa responden yang positif infeksi saluran kemih ada 10 responden (10%). Hubungan faktor risiko dengan infeksi saluran kemih yang meliputi kateterisasi, colok vagina dan kontaminasi feses saat mengedan tidak menunjukkan hasil yang bermakna secara statistik, namun setelah dilakukan uji regresi logistik dan dilakukan penyesuaian didapatkan bahwa colok vagina mempunyai hubungan bermakna dengan infeksi saluran kemih (r 0,544; p 0,019). Kesimpulan: Angka kejadian infeksi saluran kemih pada persalinan spontan di rumah sakit Mohammad Hoesin sebesar 10%. Frekuensi colok vagina memiliki hubungan bermakna dengan kejadian infeksi saluran kemih.

Abstract

Recent research in the science learning field emphasizes the importance of science learning that can empower 21st Century skills and implement metacognition-based learning. Metacognition is one of the foremost successful factors of learning achievement, which is the implementation in Indonesian schools is still being questioned. The present quantitative study aimed at gathering information on the profile of students’ metacognitive skills in Malang and figuring out whether the students’ grader influence metacognitive skills or not. This study was in ex post facto research which involves five levels of independent variables (grade level) and metacognitive skills as the dependent variable. The study involved 458 students (99 students in grade VII, 98 students in grade VIII, 98 students in grade IX, 77 students in grade X, and 86 students in grade XI) as the participants selected by homogeneous purposive sampling technique. The data of the metacognitive skills were collected by using Metacognitive Skills Rubric integrated with essay questions as the instrument. The collected data were analyzed through descriptive statistics and one-way ANOVA. The results of this study informed that the students’ metacognitive skills in Malang at each grade were categorized in “very low”. However, the level of grade significantly influenced the students’ metacognitive skills. The Senior High School (SHS) students possessed the highest level of metacognitive skills, and the students of grade VII of Junior High School (JHS) were at the lowest level. Senior High School students have better metacognitive skills than JHS students due to this kind of skills could develop by the increase of students’ grades in the process of education. The findings of this study also reveal the low level of students’ metacognitive skills. Therefore, the learning process is recommended to implement various learning form that can empower students’ metacognitive skills optimally.

Abstract

Immense students’ belief in misinformation indicates the less optimized quality of science education. However, research that analyzes the predictors of this problem is still rarely done. Biology knowledge (BK) depicts the level of biological information mastered by students; attitude toward science (ATS) is related to students' views when participating in science learning; while disbelief in conspiracy theories (DiCT) describes a person's ability to examine information that contradicts scientific truth. The current research was aimed at analyzing BK, ATS, and DiCT among Biology students, as well as the correlation between the three. The data collection instrument used was an online questionnaire comprising four main sections: demographic items, 15 Biology, and the General Public Questionnaire items, 40 ATS test items, and 8 DiCT items. Analysis was conducted on data from 820 respondents collected from February-March 2022. Some techniques for data analysis were applied, including frequency and percentage estimation, Kruskal-Wallis H test analysis, Dunn's test analysis, Kendall's Tau Correlation, and rank-based estimation regression. This research found that: 1) student’s ages and genders did not significantly contribute to any, while institutional status and study years did to BK and DiCT; 2) study program significantly contributed to ATS, and 3) ATS was found to not correlate significantly with DiCT, but BK was significant by the DiCT. Therefore, BK becomes the main competency that can protect students from unscientific conspiracy theories. This study has revealed a novelty framework about the position of knowledge and attitude in predicting students' abilities when examining misinformation.
