Abstract

The purpose of this study was to analyze the effectiveness (production, efficiency, satisfaction) of purun plant materials as a substitute for polybags in the nursery. This research was conducted in the nursery of the Faculty of Forestry, In November 2019 - February 2020 with the T test data analysis method and Boxplot comparison. The results of this study indicate that the characteristics of inorganic media bags are inorganic based, a mixture of various chemicals, and difficult to decompose. Meanwhile, organic media bags are purun-based and easy to decompose. The time needed to fill the inorganic media bag was 6.95 seconds longer than the organic media bag. The percentage of life for treatment A seedlings 92%, B treatment 92%, treatment C 96%, and treatment D 88%. The growth of Trembesi seeds is not significant. Inorganic media bag damage was only included in the 20% category (very difficult decompose), while the damage to organic media bags was in the category of 100% (easily biodegradable). The decomposition of the media bag in the inorganic media bag is very small or even absent because the number and length of roots that come out is tiny, while the organic media bag can decompose completely because of the number and length of wild rootsTujuan penelitian ini yaitu, menganalisis efektivitas (Produksi. efesiensi, Kepuasan) bahan tumbuhan purun sebagai pengganti polybag di persemaian. Penelitian ini dilakukan di persemaian Fakultas Kehutanan Universitas Lambung Mangkurat. Pada bulan November 2019- Februari 2020 dengan metode analisis data Uji T dan perbandingan Boxplot. Hasil penelitian ini menunjukkan bahwa karakteristik kantong media anorganik yaitu, berbahan dasar anorganik, campuran berbagai zat kimia, dan sulit terdekomposisi. Sedangkan kantong media organnik berbahan dasar purun dan mudah terdekomposisi Waktu yang diperlukan untuk mengisi kantong media anorganik lebih lama 6.95 detik dibandingkan kantong media organik. Persentase hidup bibit perlakuan A sebesar 92%, perakuan B 92%, perlakuan C 96%, dan perlakuan D 88%. Pertumbuhan bibit trembesi tidak ada yang signifikan. Kerusakan kantong media anorganik hanya masuk dalam kategori 20% atau sangat sulit terurai, sedangkan kerusakan kantong media organik sampai dalam kategori 100% atau sangat mudah terurai. Terurainya kantong media pada kantong media sangat kecil atau bahkan tidak ada karena jumlah dan panjang akar yang keluar sangat sedikit, sedangkan kantong media organik bisa terurai sempurna karena jumlah dan panjang akar yang keliar sangat banyak

Abstract

Pembuatan papan partikel komposit yang diperkuat dengan serat bemban (Donax caniforms) telah dilakukan dengan variasi ketebalan. Tujuan penelitian adalah untuk mempelajari pengaruh ketebalan komposit papan partikel terhadap karakteristik sifat fisis, mekanik, dan akustiknya. Penelitian dilakukan dengan metode eksperimen. Sebelum serat dipisahkan, batang bemban dibersihkan terlebih dahulu. Kemudian, serat dikeringkan pada suhu 80 0C selama 24 jam. Selanjutnya, serat digerus hingga lolos ayakan  60 mesh. Papan partikel komposit dibuat dengan perbandingan penguat serat bemban dan matrik serbuk melamin sebesar 50%:50%, dicetak pada cetakan berukuran 15 cm x 5 cm dengan variasi ketebalan 1 cm dan 1,5 cm. Hasil penelitian menunjukkan adanya peningkatan kadar air, densitas, penyerapan air, dan penurunan pengembangan tebal. Sifat mekanik yaitu MoE dan MoR juga mengalami peningkatan seiring dengan ketebalan komposit papan partikel. Sifat fisik komposit papan partikel dengan ketebalan 1 cm dan 1,5 cm telah memenuhi SNI 03-2104-1991 untuk kadar air, kepadatan, pengembangan tebal dan SNI 01-4449-2006 untuk penyerapan air. Sifat mekanik MoE dan MoR komposit papan partikel belum memenuhi SNI 03-2105-2006. Sampel komposit tergolong bahan reflektif yang sangat baik berdasarkan sifat akustiknya.

Abstract

Differentiated learning has become a very important approach in the Kurikulum Merdeka (Independent Curriculum) in meeting the diverse needs, interests, and learning styles of students. Previous research tends to focus on the use of digital media/technology, creating an urgency to describe innovative differentiated implementation strategies using CTL (Contextual Teaching and Learning) / contextual approach in schools with limited facilities, and how this strategy can, of course, influence the teaching and learning process and student learning outcomes in elementary schools. This study uses a qualitative method with a descriptive case study design conducted at SDN Kelayan Timur 7 Banjarmasin, focusing on Grade IV. The participants in this study were one school principal and one teacher, along with 20 students. Data collection was carried out through observation and semi-structured interviews, as well as document analysis. The data was analyzed inductively using an interactive model (data reduction, data display, and conclusion drawing) combined with thematic analysis. The teacher's implementation strategy was carried out through three differentiations: content, process, and product, which were grouped based on the level of ability or learning needs, divided into three categories (Apple, Blueberry, Cherry). The contextual approach was also delivered by integrating the material into everyday life. The impact is that learning becomes more adaptive, relevant, and increases student enthusiasm, as well as showing an improvement between the initial and final assessments. However, the challenges faced also include the demand for extra preparation by the teacher, the need for high levels of attention, and limited learning time. Suggested solutions include utilizing collaboration, peer tutoring, and the teacher's flexible division of attention across all groups. This contextual-based strategy is an effective innovation to be implemented in schools with limited use of digital media/technology facilities.
