Pengaruh Konsentrasi Pupuk Organik Cair Super Bionik dan Varietas Kacang Tanah terhadap Pertumbuhan dan Hasil

Effect of Organic Liquid Fertilizer and Peanut Variety on the Growth and YieldABSTRACT. The objective of this study were to investigate several varieties and liquid organic fertilizer on the growth at the yield of peanut of the tsunami affected area and also to identify the interaction between the two factors. The research was conducted at the Lamnyong river flood plain which is located at west sector of Komplek Pelajar Mahasiswa (KOPELMA) Darussalam – Banda Aceh from March to Mei 2009. Randomized completely block design with two factor was used on this experiment using three replications. The first factor was peanut variety (i.e. Singa, Kuala Batee and Tangse), and the second factors was Super Bionik fertilizer concentrations (i.e. 0 cc; 0.9 cc; 1,8 cc /225cc). The variety significantly influenced the plants height on 45 days after planting, the amount of ginofore, the plant wet weight, and 100 seed weight, however the variety not significantly influenced other parameters (i.e. the amount of the branches at 45 days after planting, the total pods, and the amount of full pod). The result showed that Super Bionic concentrations not significantly influenced all parameters observed, and no interactions between the variety and the fertilizer concentration occurred on the parameters observed

Implementation of Blended Learning to Improve Critical Thinking Skills and Motivation

The aims of this research are to 1) know the differences of Critical Thinking Skills from blended learning in Diversity dan Classification of Invertebrate course, 2) find out the result of the blended learning implementation concerning study motivation in Diversity dan Classification of Invertebrate course at Biology Education program, 3) know the effect of blended learning on critical thinking in solving problems. Blended learning-based learning is a combination of face-to-face and online learning. Online learning is learning through various learning facilities such as using material sharing via PowerPoint, WAG, email, recitation of downloading material from various journals without the need for a face-to-face meeting. The research subject were students of the second-semester Biology education program. Data collection on critical thinking skills was taken from test scores after learning eight times, learning motivation data was taken through a questionnaire. Different test analyses using One Way ANOVA with a prerequisite test consist of normality test (Saphiro-Wilk Test) and homogeneity with Levene Test. The questionnaire analysis uses Rasch analysis with the help of Winsteps version 4.6. From the results of the study, it can be concluded that 1) there is a significant difference in critical thinking skills in blended learning and online learning, 2) there is a difference in learning motivation from blended learning and online learning, 3) there is a positive effect on critical thinking skills in solving problems given in blended learnin

Keanekaragaman Avifauna Daerah Terbuka dan Tertutup di Wilayah Kampus Kentingan Universitas Sebelas Maret

Perubahan kondisi lingkungan akibat pembangunan sarana dan prasarana akan mempengaruhi kehidupan bagi beberapa organisme termasuk burung. Penelitian ini bertujuan untuk membedakan keanekaragaman burung pada dua habitat yang berbeda di lingkungan kampus UNS sehingga data yang dihasilkan memberi gambaran kualitas daya dukung lingkungan UNS. Penelitian ini dilaksanakan pada bulan April - Mei 2021  di Danau Fakultas Pertanian (FP) UNS dan kawasan Hutan Fakultas Kedokteran (FK) UNS. Subjek penelitian merupakan burung-burung yang terdapat di  kedua lokasi. Teknik pengumpulan data menggunakan metode pointcount  yakni mengamati subjek penelitian dengan diam di suatu tempat dengan batasan jarak tertentu. Analisis data menggunakan deskripsi kualitatif untuk menguraikan jenis spesies, dan analisis secara kuantitatif untuk mengetahui indeks keanekaragaman jenis, indeks kelimpahan jenis, dan indeks dominansi. Prosedur penelitian dilakukan mulai dari penentuan lokasi, penentuan transek, penentuan titik hitung, pengamatan, akumulasi data, analisis data, dan terakhir kesimpulan. Hasil penelitian menunjukkan tidak terdapat perbedaan nyata keanekaragaman jenis burung dari kedua lingkungan yang diamati. Danau FP UNS memiliki keanekaragaman sebesar 2,016 sedangkan Hutan FK sebesar 2,086. Kategori keanekaragaman tergolong sedang sehingga dapat disimpulkan daya dukung Danau FP dan Hutan FK UNS cukup dengan kestabilan ekosistem yang cukup dan tekanan ekologis rendah

Facile Synthesis of Hierarchically Structured Magnetic MnO2/ZnFe2O4 Hybrid Materials and Their Performance in Heterogeneous Activation of Peroxymonosulfate

In heterogeneous catalysis for water treatment, feasible recovery of nanocatalysts is crucial to make the process cost-effective and environmentally benign. In this study, we applied two strategies, for example, magnetic separation and hierarchical structure of solid catalysts, to ensure manganese catalysts are readily separable, meanwhile their catalytic performance was retained by the nanosized structure of MnO2 nanosheets or nanorods. ZnFe2O4 was used as the magnetic core and MnO2 corolla-like sphere consisting of nanosheets, and sea-urchin shaped structure made of nanorods, were fabricated by a hydrothermal method at 100 and 140 °C, respectively. Crystalline structure, morphology and textural property of the materials were investigated. The prepared catalysts were able to effectively activate peroxymonosulfate (PMS) to generate sulfate radicals for catalytic oxidation of a typical organic pollutant of phenol. After the heterogeneous catalysis, the catalysts were easily recovered by applying an external magnetic field. The effects of temperature and repeated use on the degradation efficiencies were evaluated. The generation and evolution of sulfate radicals and phenol oxidation were studied using both competitive radical tests and electron paramagnetic resonance (EPR)
