Abstract

The decline in Timorese local garlic yields will have an impact on farmers' income and the existence of the garlic. One of the decline factors is production. The purpose of this study is the implementation of an electric field as a stimulant for garlic growth. The electric field used is an AC electric field with an output frequency of 1.0 kHz. The variation of the electric field used is 1.28 kV/m, 1.55 kV/m. 1.80 kV/m, 2.12 kV/m and 2.48 kV/m. The results showed that exposure to an electric field in garlic resulted in a better germination rate, average germination time, and shoot and root growth rate compared to the control. The treatment of exposure to an electric field of 1.55 kV/m resulted the most optimum in the germination rate, average germination time and growth rate of shoots and roots with the respective values (11.4 ± 0.6) %/etmal, (1.4 ± 0, 1) day, (2.83 ± 0.09) mm/day, and (2.04 ± 0.09) mm/day. Increasing germination, shortening the average germination time and growth rate are expected to increase local Timor garlic production.

Abstract

Abstrak: Biologi merupakan pelajaran IPA yang mempelajari kehidupan organisme, termasuk struktur, fungsi dan pertumbuhannya. Pembelajaran biologi perlu menambahkan keterampilan menggunakan alat peraga atau praktikum seperti pengamatan bentuk sel, ukuran sel, serta pergerakan mikroorganisme. Oleh karena itu perlu adanya sarana berupa mikroskop. Keterbatasan ketersedian mikroskop yang dimiliki sekolah mengakibatkan guru kurang optimal dalam melakukan penelitian dan pengajaran. Oleh karena itu perlu adanya optimalisasi kinerja mikroskop dengan cara mengubah mikroskop konvensional menjadi digital. Berdasarkan permasalahan tersebut, maka diadakan pelatihan Optimalisasi Mikroskop konvensional menjadi digital bagi guru biologi. Pelatihan mulai dengan pengenalan fungsi masing-masing komponen alat tambahan seperti kamera, lampu, dan perangkat lunak penangkap gambar. Selanjutnya dilakukan pelatihan instalasi dan mengoperasikan perangkat lunak penangkap gambar serta pengamatan menggunakan mikroskop digital. Pelatihan terakhir yaitu analisis gambar yang diperoleh dari mikroskop digital menggunakan perangkat lunak Image J. Hasil evaluasi menunjukkan bahwa 4 guru biologi sudah mampu mencapai level 3 yang artinya guru menguasai penggunaan mikroskop digital, penggunaan perangkat lunak serta melakukan analisis gambar menggunakan Image J. Tingkat pemahaman guru menggunakan mikroskop digital mencapai 90%. Abstract: Biology is a science lesson that studies the life of organisms, including their structure, function and growth. Biology learning needs to add skills using teaching aids or practical such as observing cell shape, cell size, and the movement of microorganisms. Therefore, it is necessary to have a tool in the form of a microscope. The limited availability of microscopes owned by schools causes teachers to be less than optimal in conducting research and teaching. Therefore, it is necessary to optimize the performance of the microscope by converting conventional microscopes to digital ones. Based on these problems, a training on Optimization of Conventional Microscopes to be Digital was held for biology teachers. The training begins with an introduction to the function of each component of the auxiliary equipment such as cameras, lights, and image capture software. Furthermore, training on the installation and operation of image capture software and observations using a digital microscope was carried out. The last training was analysis of images obtained from digital microscopes using Image J software. The evaluation results show that 4 biology teachers have been able to reach level 3, which means that teachers able to use of digital microscopes, use software and image analysis using Image J. The level of understanding of teachers using digital microscopes reaches 90%

Abstract

Local upland rice (Oryza sativa L.) is a type of cereal crop that has the potential for dry land areas. Farmers in Kupang plant upland rice/local rice that has been consumed and used for generations and is considered by the surrounding community as part of their ancestral heritage. The materials used in this research were local upland rice varieties as a result of exploration. The varieties of six local upland rice of Kupang studied in this research had different rice characters in terms of its weight, volume, density and yield.'Aen Molo' has the highest weight per grain and per 1000 grains, namely 0.024 g and 24.95 g, also the highest volume of 1000 grains of rice is 30 ml, while 'Aen Lekes' has the lowest weight per grain and per 1000 grains, namely 0.020 g and 19.66 g and also the lowest volume of 1000 grains, namely 23 ml. The Iodine test results showed that the local rice of Kupang was classified in the regular or non-glutinous rice group. Meanwhile, Alkali test results show that the six samples of local upland rice have a high gelatinization temperature which indicates that local upland rice in Kupang Regency has high amylose content.

Abstract

Salah satu alasan sekolah masih belum dibuka secara penuh hingga kini adalah potensi terjadinya penularan melalui siswa-siswa yang berkumpul dalam waktu lama di ruang tertutup. Beberapa penelitian menunjukan bahwa menutup sekolah akan memperlambat perkembangan infeksi. Namun, langkah-langkah yang lebih luas seperti social distancing, terbukti memiliki efek pengendalian yang lebih besar. Risiko dari pembukaan sekolah akan bergantung pada seberapa baik sekolah mengendalikan penularan, misalnya dengan penggunaan masker dan membatasi okupansi. Oleh karena itu, perlu dilakukan kembali penguatan perilaku untuk mencegah penularan penyakit Covid-19 kepada siswa dan guru. Bentuk Kegiatan Pengabdian yang dilakukan adalah pembagian masker dan edukasi mengenai dampak penyakit Covid-19 kepada siswa dan guru SDK Seoam 1 Eban, Kefamenanu. Hasil dari kegiatan ini adalah para siswa dan guru dapat melakukan protokol kesehatan secara sadar dan benar yaitu melalui 3M: memakai masker, menjaga jarak dan menghindari kerumunan, serta mencuci tangan pakai sabun. Kata Kunci: Covid-19, Protokol Kesehatan, Guru dan Siswa

Abstract

Garlic is a horticultural plant that is used as a flavoring and also has pharmacological benefits. Local Timor Garlic, known as Eban Garlic, is one of the local varieties of garlic from Indonesia. Eban garlic is one of the leading commodities in North Central Timor Regency whose cultivation is carried out for generations. To increase the yield of garlic, the growth and development of these plants must be considered. Growth and development are part of the biological processes of organisms. In plants, primary growth occurs at the growing point, namely the meristematic tissue at the tip of the shoot and the tip of the plant root. In this article, we will examine the effect of exposure to magnetic fields on the mitotic index of Eban garlic root tip cells. The results showed that the greater the exposure to a given magnetic field, the smaller the mitotic index. The control treatment had the highest mitotic index of 36.56% and exposure to a magnetic field of 20.03 mT had the lowest mitotic index of 20.03%. The results of the study based on the time of observation, the prophase phase had the greatest mitotic index, which was 84.21% in the control treatment. This means that exposure to a magnetic field that is too high can slow down the cell division of Eban garlic roots.
