Abstract

PENGGUNAAN TEKNIK RADIOGRAFI NEUTRON UNTUK MENDETEKSI SECARA CEPAT TOLERANSI  TANAMAN PADI TERHADAP CEKAMAN KEKERINGAN. Telah dilakukan penggunaan teknik radiografi neutron untuk  mendeteksi  secara  cepat  toleransi  tanaman  padi  terhadap  cekaman kekeringan. Dua jenis padi yaitu padi gogo dan padi sawah  dipilih sebagai obyek penelitian. Tanaman padi gogo yang diketahui lebih toleran terhadap cekaman kekeringan dibanding padi sawah diamati perkembangan akarnya setelah mengalami cekaman kekeringan dengan mengurangi kandungan air tanahnya hingga 50% dan 25%. Pengamatan perkembangan akar tanaman diamati untuk usia tanaman 2, 3, 4, serta 10 minggu. Pengamatan dengan fasilitas radiografi neutron, RN1 di reaktor  RSG-GAS  secara  in-situ  menunjukkan bahwa untuk usia padi di bawah 4 minggu perkembangan akar tidak teramati dan  akar  mulai teramati dengan jelas pada usia tanaman 10 minggu. Hasil awal menunjukkan babwa padi gogo terbukti lebih toleran terhadap cekaman kekeringan dengan profil  akar yang relatif  lebih  besar  dan  mampu  bertahan  lebih lama terhadap cekaman kekeringan dibanding dengan padi sawah. Hasil ini  menunjukkan  bahwa  teknik radiografi neutron dapat  menjadi metode alternatif untuk mendeteksi toleransi tanaman padi terhadap cekaman  kekeringan.

Abstract

AbstractA total of 98 actinomycetes were isolated from the soil and litter samples collected from the cacao and coffee plantation in Lombok Island, West Nusa Tenggara, Indonesia. These isolates were screened for their antimicrobial activity. Among 98 isolated strains, only 24 isolates showed antimicrobial activity against test microorganisms of which 20.4% were active against Bacillus subtilis BTCC B-612, 14.3% against Staphylococcus aureus BTCC B-611, and 5.1% against Escherichia coli BTCC B-609. Out of these 24 isolates, 3 were found to be able to grow in medium containing 3 mM Selenium oxide of which the culture were changed color to red. Two of the best strains, L-155 and L-156, were selected for assessing production of Selenium nanoparticles. Bioreduction of selenium nanoparticles was confirmed by UV–visible spectrophotometer which showed peak between 300 and 320 nm. Biosynthesized selenium nanoparticle from isolate actinomycetes L-155 and L-156 were found to have a broad spectrum of activity against the tested microorganisms: Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Micrococcus luteus, and Candida albicans. This study showed rapid and eco-friendly synthesis of selenium nanoparticles from soil actinomycetes. Most of these active isolates revealed to possess antibacterial property.

Abstract

Artikel ini menganalisis tentang penggunaan ragam jenis pensil untuk mengembangkan kemampuan menggambar dengan teknik arsir bagi mahasiswa PGSD UNJ. Penelitian ini melibatkan tiga gambar dari tiga mahasiswa PGSD UNJ yang telah mengampu mata kuliah Pendidikan Seni Rupa SD. Penelitian ini bertujuan agar mahasiswa PGSD UNJ dapat memperhatikan unsur-unsur gambar seperti titik, garis, bidang, ruang, terang-gelap, gradasi warna, dan tekstur. Selain itu, mahasiswa dapat menggunakan ragam jenis pensil seperti pensil berkode B yang terdiri dari 2B, 4B, dan 6B dalam menggambar dengan teknik arsir, sehingga menghasilkan gambar yang memiliki nilai estetika. Penelitian ini merupakan penelitian deskriptif kualitatif dengan metode studi dokumentasi dan wawancara. Melalui penggunaan ragam jenis pensil berkode B ini, mahasiswa dapat memenuhi unsur-unsur gambar seperti adanya efek objek gambar terang-gelap, gradasi warna dengan saturasi tinggi hingga rendah, serta tekstur Penggunaan ragam jenis pensil dalam menggambar dengan teknik arsir dapat berkembang apabila mahasiswa dapat terus berlatih menggores beragam jenis pensil dengan tekun. Apabila unsur-unsur gambar belum terlihat pada objek gambar dengan teknik arsir, maka mahasiswa dapat berlatih menggambar kembali dengan tekun.

Abstract

The goal of the article is to improve the thermal properties and energy efficiency of the walls and facades of the buildings by introducing the phase change material in the bricks. This study focuses on the thermal insulation capabilities of a paraffin-ice bag PCM mixture, aiming to enhance the thermal inertness of the bricks. The paraffin wax exhibits a high latent heat and is chemically stable, while the ice bags, with their low temperatures, serve as effective thermal regulators. They complement each other to address challenges such as the low thermal conductivity of paraffin and the leakage of low phase change transition temperature in paraffin. We made use of two types of paraffin and ice bag PCMs in a 50:50 ratio and embedded them in standard bricks. During the experiment, we coated the brick surfaces with liquid cement to enhance the hydraulic resistance of the PCM. Next, we inserted wires known as packing plugs into the bricks and filled the holes with powders. We also subjected the bricks to heating and cooling in cycles, ensuring the temperatures remained within a specified range. During the experiment, temperature sensors were utilized to capture data concerning thermal performance. The authors reached the conclusion that PCM polymer composite bricks possess a lot of promise such walls are being able to maintain their thermal performance parameters. When PCM-enhanced bricks are utilized, temperature changes were significantly restricted, staying constant during the times of peak heating and cooling. The PCM bricks also displayed efficient absorption and gradual release of energy due to the high energy transfer rates during phase change. This study suggests that PCM polymer composite bricks are cost-effective for the energy performance of buildings.

Abstract

This research examines the effect of bricks enhancement with phase change material (PCM) consisting of paraffin on their thermal considerations. The experimental methods were aimed at investigating the mechanisms of temperature transfer throughout the thermal rounds, mimicking diurnal fluctuations of temperature. Due to the high amount of latent heat contained in paraffin a portion of it was transferred into regular bricks with temperature probes tracing the heat processes. It is shown that enhancement of bricks with PCM reduced temperature range and controlled the rate of heat transmission more than the ordinary bricks did. It was significant that the PCM-embedded bricks did not drift in heat and were able to stock up excess heat during the day and release it at night which resulted in monumental energy efficiency and comfort in thermal standing. The conversation additionally seeks to bring out the function of paraffin in insulation which does not only save energy consumption but goes forward to maintain comfortable temperatures within the building. The study finally achieved its goal and assert that energy saving with the use of PCM enhanced bricks in construction makes it a preferable material in regards to energy and the fight against climate change.
