Serat pinang diberi perlakuan NaOH 2,5%, 5%, 7,5% dan 10% kemudian serat direndam selama 4 jam. Tahap penelitian ini adalah penghalusan serat, perendaman serat, ekstraksi selulosa, pemutihan serat, proses sonikasi, dan pembentukan film bioplastik dengan pencampuran antara selulosa dengan matrik film polyvinil alcohol (PVA). Untuk mengetahui karakteristik sifat mekanik menggunakan alat uji tarik. Nilai optimum kekuatan tarik diperoleh pada variasi konsentrasi NaOH 5 % yaitu sebesar 1,27 MPa, nilai regangan tertinggi pada konsentrasi NaOH 10 % yaitu 0,077 dan modulus elastisitas tertinggi pada NaOH 5 % yaitu sebesar 17,39 MPa. Nilai absorbansi tertinggi di peroleh pada konsentrasi NaOH 2,5 % yaitu sebesar 2,897. Penelitian ini memiliki prospek untuk mengembangkan bahan alam untuk pembuatan material maju berupa film bioplastik seperti kaca ITO, dan anti gores handphone.Â Research has been carried out on the characterization of of PVA fibrous celluloseâ€™s mechanical properties, betel nut skin, which has NaOH treatment.

Telah dilakukan penelitian tentang penerapan proteksi radiasi pada pekerja radiasi di Instalasi Radiologi RS Naili DBS, RS Selaguri dan RS UNAND.Â Penelitian bertujuan untuk mengevaluasi dosis radiasi perorangan yang diterima pekerja radiasi, mengestimasi efek yang diterima pekerja radiasi serta mengevaluasi penerapan prinsip proteksi radiasi bagi pekerja radiasi.Â Pada penelitian digunakan data sekunder untuk dosis radiasi perorangan pekerja radiasi dan data primer untuk laju paparan radiasi di instalasi radiologi menggunakan surveymeter fluke dengan tegangan pesawat sinar-X 80 kV.Â Hasil penelitian menunjukkan dosis radiasi perorangan yang diterima pekerja radiasi pada ketiga rumah sakit dalam waktu 3 bulan di bawah Nilai Batas Dosis (NBD) yaitu (0-0,46) mSv dengan acuan NBD berdasarkan Perka BAPETEN No. 4 Tahun 2013 yaitu 20 mSv dalam satu tahun.Â Efek radiasi yang diterima pekerja radiasi diperkirakan efek stokastik karena dosis radiasi perorangan yang diterima pekerja radiasi rendah.Â Penerapan proteksi radiasi terkait waktu, jarak, dan penggunaan perisai radiasi ruang memenuhi standar BAPETEN No. 4 Tahun 2013, akan tetapi penggunaan APD sebagai perisai diri belum mengikuti standar.Â A research on the application of protection from radiation has been done in the radiology installation at Naili DBS Hospital, Selaguri Hospital, and University of Andalas Hospital.Â This study aims to evaluate the radiation dose received by radiation workers, to estimate the effect of the radiation to the radiation workers and to evaluate the principal application of radiation protection to radiation workers. The research uses primary data for the radiation exposure rate in radiology installation by using survey meter fluke with 80 kV of X-ray energy and secondary data for the radiation dose for each individual. The result shows that the radiation dose received by the radiation workers on the aforementioned hospitals are below the Dose Limits (NBD) based on Perka BAPETEN No. 4 of 2013, which is (0â€“0.46) mSv for 3 months compared to 20 mSv for year which is the maximum amount allowed. The radiation effect sustained by the radiation workers is projected to be stochastic, due to the low rate of radiation dose rate. The application of radiation protection related to time, distance and the usage of a radiation shield meets the required standard of BAPETEN, but the usage of personal protective equipment as a self-defence mechanism has not met the required standard yet.

В статье рассматривается правовой механизм изъятия земель сельскохозяйственного назначения. Установлено, что существующие подходы не учитывают ряд экологических факторов, и требуют доработки. Действующий перечень необходимо дополнить критериями, более подробно характеризующими состояние почв. При оценке неиспользования земель следует шире применять методы дистанционного мониторинга. Также на законодательном уровне следует предусмотреть мероприятия по сбору и систематизации данных прошлых почвенных и агрохимических обследований, которые послужат исходными показателями для сравнительной оценки.
The article deals with the legal mechanism of seizure of agricultural land. It is established that the existing approaches do not take into account a number of environmental factors, and require further development. The current list should be supplemented with criteria that characterize the state of the soil in more detail. Remote monitoring methods should be used to assess nonuse of land. Also on the legislative level should provide activities for collection and systematization of historical data of soil and agrochemical survey, which will serve as baselines for comparative evaluation.

Earthquake and tsunami struck Palu bay on September 28, 2018, and has affected the entire coast. BCF habitat on Palu bay was lost by the tsunami. BCF depends on its habitat for survival. Banggai cardinalfish is a paternal mouthbrooder with direct development, without pelagic phase and sedentary movement. If habitat extinction occurs, there is a small chance for the population to recover naturally. The BCF spread was naturally uneven, although on a relatively uniform habitat. This research aimed at determining BCF biodiversity in the Gulf of Palu and examined the distribution of BCF in Palu bay. The Determination of BCF population was done by visual census through Fish Belt Transect method and Swim Survey method, besides the conditions and habitat composition were done by using Point Intercept Transect (PIT) method. Surveys were carried out by2 times observations with 5 meters width and the transect length in a repeat was 25 meters. The results obtained the living habitat of P. kauderni on both observation locations consist of hard corals, anemones, and sea urchins. The diversity index obtained indicated that the diversity and community stability were low, while uniformity index indicated that the distribution between individual types of reasonably uniform. In contrast, the dominance index showed that the size of the adults was more dominating on the habitat on both of the observation locations. These findings would be a reference for habitat restoration of Banggai cardinalfish (BCF) post-disaster.
