Authors: Duda T. , Rothardt T. , Babiak Z. , Mendelsohn M. 
Published: October 2022

Abstract
This study investigates the influence of plasma gas composition on deposition efficiency achieved during atmospheric plasma spraying and the properties of the resulting deposits. In the experiments, ternary mixtures of argon, hydrogen, and helium are used in different combinations and flow rates to spray Al2O3-TiO2 and ZrO2-Y2O3 powders on test substrates while measuring deposition efficiency. Several coating properties are measured, including porosity, hardness, and bond strength, and correlated with plasma gas ratios. Paper text in German.

Authors: Fuadiah Nyiayu Fahriza 
Published: October 2022

This study aims to describe the characteristics of the Theory of Didactical Situation (TDS), especially in mathematics as an alternative information for educators to design learning according to the characteristics and needs of students and the learning objectives to be achieved. This study uses a literature review to explain the characteristics of TSD obtained from scientific papers and articles, relevant books, research reports, and other scientific sources. Based on the literature review, there are three characteristics of TDS, namely TDS' special attention to mathematics and its epistemology, epistemological characteristics, and students' cognitive dimensions. These three things are interrelated and support each other. This article also discusses the concept of adaptation through understanding adidactical situations and milieu and acculturation through understanding didactic situations and didactic contracts. In conclusion, through didactic situations that are built during learning and facilitated by the teacher, it is expected to be able to develop the potential of students, namely students can build their own knowledge to be achieved.

Published: October 2022

Sektor pariwisata berperan penting sebagai salah satu sumber pendapatan negara yang dapat mendorong pertumbuhan ekonomi nasional. Dengan munculnya COVID-19 mengakibatkan runtuhnya pariwisata sektor lainnya. COVID-19 berdampak negative terhadap industry pariwisata baik dalam hal kunjungan wisatawan domestic maupun wisatawan mancanegara. Hal ini memaksa perubahan kondisi dari era normal menjadi era new normal. Yang tentu saja akan menyebabkan perubahan perilaku masyarakat ketika berwisata. Penelitian ini bertujuan untuk mengidentifikasi perilaku para wisatawan terhadap niat untuk berkunjung ke destinasi wisata melalui variabel fear of covid 19, travel anxiety dengan variabel risk attitude sebagai variabel intervening. Data responden diperoleh melalui kuesioner yang disebarkan secara online kepada 210 responden yang berdomisili di lima kabupaten/kota dengan kunjungan wisata tertinggi di Provinsi Sumatera Barat. Data diolah dengan secara kuantitatif menggunakan SMART-PLS 3.0. Pada penelitian ini diperoleh hasil bahwa ketakutan masyarakat untuk berwisata pada era new normal tidak sebesar saat pandemic covid 19 sedang tinggi. Hal ini dibuktikan bahwa pada era new normal masyarakat tetap memiliki niat (revisit intention) untuk melakukan perjalanan wisata meskipun memiliki kecemasan (fear of covid 19) dan sikap atas resiko (risk attitude) akan tertular COVID-19. Ketakutan responden terhadap tertular covid 19 (fear anxiety) dibarengi dengan tetap memperhatikan konsep CHSE ( Cleanliness, Health, Safety dan Environment).
KAMPUNG AKUAPONIK: PEMODELAN TEKNOLOGI AKUAPONIK GUNA MENINGKATKAN KETERAMPILAN DAN KEMANDIRIAN MASYARAKAT TEMPILANG
Authors: Kurniawan Andri 
Published: October 2022

Pemanfaatan lahan sempit dan tidak produktif melalui kegiatan budidaya ikan merupakan salah satu cara meningkatkan produktivitas lahan. Teknologi akuaponik memadukan budidaya ikan dan sayur dengan sistem resirkulasi dinilai sebagai teknologi sederhana, tetapi tepat guna.
Teknologi ini mengedepankan efisiensi lahan dan pemanfaatan limbah organik ikan sebagai pupuk bagi tanaman yang berada di atasnya. Pengembangan teknologi ini dapat menghasilkan multile product dalam satu siklus produksi. Lebih jauh, teknologi ini mampu meningkatkan kemandirian serta produktivitas masyarakat sehingga secara tidak langsung diharapkan dapat menunjang perekonomian dan kesejahteraannya.
Kegiatan KKN IX yang dilaksanakan oleh Universitas Bangka Belitung (UBB) di Desa Basun, Desan Dam 3, dan Desa Kelekak Kabung di Kecamatan Tempilang adalah menifestasi peran dharma pengabdian UBB kepada masyarakat. Penerapan teknologi akuaponik diharapkan dapat menghadirkan pengetahuan dan keterampilan baru bagi masyarakat sehingga optimalisasi lahan non produktif dapat ditingkatkan dan mampu menghasilkan sesuatu yang lebih bermanfaat dan bernilai ekonomis.
MEMBANGUN DUSUN TUING DARI SEKTOR PERIKANAN, PARIWISATA, DAN PERTANIAN
Authors: Karsiningsih Eni 
Published: October 2022

Dusun Tuing Desa Mapur Kecamatan Riau Silip Kabupaten Bangka merupakan salah satu dusun tertinggal di Kabupaten Bangka. Faktor utama penyebab ketertinggalannya adalah akses jalan yang sangat jelek. Akan tetapi, Dusun Tuing menyimpan potensi pariwisata yang sangat indah dan perikanan yang belum terlalu diekplor serta pertanian yang masih perlu dikembangkan. Sehingga perlu pendekatan-pendekatan yang dilakukan untuk melakukan pembenahan dan pengembangan terhadap sektor-sektor tersebut seperti membuat alat bantu tangkap ikan, memberi bantuan GPS, melakukan penataan dusun, melakukan sosialisasi dengan pemerintah daerah, membentuk kelompok tani, membuat demplot dan vertikultur sayur mayur, pemberian bibit ayam kampung super dan bibit karet, sosialisasi UU status kepemilikan lahan, dan membuat RAB pengaspalan jalan. Sebagian besar kegiatan-kegiatan pengabdian di Dusun Tuing ini berhasil dilakukan sehingga masyarakat dapat membuat rumpon cumi dan rumpon ikan serta tahu titik-titik penangkapan dengan menggunakan GPS, tahu metode demplot dan vertikultur dan mampu mengembangbiakkan ayam kampung super. Oleh karena itu, agar Dusun Tuing dapat keluar dari belenggu ketertinggalan, sebaiknya pemerintah daerah segera melakukan pengaspalan jalan berdasarkan RAB yang telah dibuat, melakukan sosialisasi Perda No. 1 tahun 2013, dan bekerjasama dengan Univeritas Bangka Belitung untuk membuat master plan pengembangan pariwisata di Dusun Tuing.
