Abstract

ABSTRAKTujuan penelitian ini untuk menganalisis konsumsi air putih terhadap konsentrasi siswa, mengetahui kebiasaan konsumsi air putih siswa dalam 24 jam, dan mengetahui gambaran konsentrasi siswa. Adapun sample yang digunakan adalah 10 subjek siswa kelas IV A SD Negeri Sudimara Barat 5.Metode penelitian deskriptif dengan pendekatan kualitatif. Pada tahap awal, subjek dimintamencatat recall 24 jam asupan konsumsi air putih tentang seberapa banyak asupan konsumsi air putih, selanjutnya peneliti mengelompokkan kedalam 2 kategori yaitu cukup dan kurang asupan air putih, setelah itu subjek dites dengan menggunakan grid tes konsentrasi. Dari data yang ada diambil kesimpulan bahwa dari 10 subjek sebanyak 2 subjek masuk dalam kategori konsentrasi baik yaitu subjek dengan konsumsi air putih cukup, 6 subjek masuk dalam kategori konsentrasi sedang yaitu 5 subjek dengan konsumsi air putih kurang dan 1 subjek dengan konsumsi air putih cukup, dan 2 subjek masuk dalam kategori konsentrasi buruk dengan konsumsi air putih kurang.Kata Kunci: Siswa, Konsentrasi, Air.

Abstract

Pemetaan spasial kerentanan airtanah terhadap pencemaran merupakan bagian dari pengelolaan keberlangsungan sumber daya air. Kerentanan airtanah terhadap pencemaran dapat diketahui dari parameter geologi dan sifat hidrogeologi. Tujuan dari penelitian ini adalah mengetahui zona kerentanan airtanah terhadap pencemaran di Kota Jember. Metode yang digunakan adalah pemodelan multi kriteria dengam mempertimbangan sifat hidrogeologi airtanah dengan metode SINTACS. Parameter yang digunakan untuk penilaian kerentanan antara lain Kedalaman freatik/soggiacenza (S), infiltrasi/infiltrazione (I), kondisi tak jenuh/non saturo (N), tekstur tanah/tipologia della copertura (T), media akuifer/acquifero (A), kondivitas hidrolik/hydrolic conductivity (C), kemiringan lereng/superficie topografica (S). Setiap nilai dari masing-masing parameter kerentanan diberi faktor pembobot untuk mendapatkan skenario kerentanan airtanah terhadap pencemaran. Perhitungan dengan penilaian bobot diperlukan untuk pemodelan atau sekenario dampak pencemaran. Perhitungan dari nilai dan bobot diperoleh dari penilaian linier seluruh variabel dengan menghasilkan nilai indeks kerentanan kemudian dikelaskan terhadap tingkat kerentanan airtanah. Berdasarkan hasil penelitian diketahui dua kelas kerentanan. Tingkat kerentanan airtanah terhadap pencemaran agak tinggi dengan luas 26 km2 (70%) dan kerentanan tinggi seluas 11 km2 (30%) dari luas wilayah kota Jember. Faktor yang dominan mempengaruhi antara lain parameter kedalaman freatik airtanah, laju infiltrasi dan zona tak jenuh. Secara umum tingkat kerentanan airtanah terhadap pencemaran agak tinggi.

Abstract

Homeless children are unique and creative individuals. Most of the time these homeless children are based in the city center, however, they are often marginalized from the limelight. The homeless children need to be given the opportunity and the choice to improve their potential. The street corners of Banjarmasin are not the ideal home for these children. The Youth Development Center is the place to develop the potential of homeless children through creative fields with a sense of home in the design. It will be the hub for these children to express themselves through their creations and receive the opportunity to learn more without the space restriction. The Youth Development Center can also be a place for society to appreciate the homeless children’s potential. The design strategy uses the Third Place method as a space for interaction and solution of problems using the concept of Flexible Architecture so that space is defined not only by its function but by the potential of the space itself.

Abstract

The pandemic of the Covid-19 Virus was used by hoax producers as momentum to spread false information. It has also happened in Bali Province. All parties must cooperate to stop the spread of hoaxes and additional media were needed to verify the correctness of the information and convey facts to the public. This research examined the category of hoaxes related to Covid-19 and the use of the “Bali Carify” social media account as a medium for publishing fact-checking results as well as educating the public about the 7 categories of hoaxes. This research used two data sources: reports were released by Bali Province Office of Communication, Information, and Statistic (Diskominfos) and social media monitoring results. Data collection techniques use secondary data in the form of journals, books, and mass media that were relevant to the problems in the study. The object of this research was hoaxes related to Covid-19. This research applied the theory of classification hoaxes into seven categories and theory to verify the correctness of the information. Data analysis was performed inductively.  The data period was limited to only from January to June 2020 (six months). From 14 samples of hoax data that content was related to the Covid-19 phenomenon in Bali, one data was taken that can represent the hoax in the specified category. The results found that there were six categories of hoaxes circulating in Bali, namely parody, misleading content, fake content, fake content, false context, and manipulated content.

Abstract

Bencana gerakan tanah atau longsor memiliki dampak daya rusak yang tinggi dan dapat mengubah kondisi fisik dan lingkungan disekitar lereng. Selain dampak tersebut, pemanfaatan sumber daya alam dan penataan ruang yang tidak tepat menyebabkan risiko bencana gerakan tanah menjadi lebih besar. Salah satu upaya mitigasi dalam kebencanaan gerkan tanah adalah identifikasi zona kerawanan gerakan tanah. Seperti yang diamanahkan oleh Undang Undang no.24 tahun 2007 tentang penanggulangan bencana, dengan langkah mitigasi pemetaan zona kerawanan gerakan tanah atau longsor. Pemetaan gerakan tanah dapat dimodelkan dengan pendekatan spatial multi criteria, dimana parameter yang mempengaruhi longsor yaitu kemiringan lereng, jenis batuan, struktur geologi, kegempaan, gerakan tanah, tata guna lahan / penggunaan lahan diberikan nilai dan bobot yang dominan terhadap gerakan tanah. Parameter dengan bobot yang paling tinggi merupakan parameter yang menentukan potensi gerakan tanah. Perhitungan skor diperoleh dari perhitugan penjumlahan linier semua parameter. Skor dengan nilai paling tinggi menunjukkan zona kerawanan gerakan tanah tinggi atau bencana tinggi. Berdasarkan latar belakang tersebut, maka tujuan dari penelitian ini adalah mengetahui distribusi keruangan (spasial) kerawanan gerakan tanah. Hasil penelitian menunjukkan bahwa di Kabupaten Bangkalan terdapat empat klasifikasi kerawanan gerakan tanah, yaitu sangat rendah di dataran pantai, kerawanan rendah pada daerah pesisir, kerawanan menengah pada morfologi perbukitan, dan kerawanan tinggi pada morfologi perbukitan pada bagian tengah dengan lereng yang curam. Secara umum tingkat kerawanan gerakan tanah di Kabupaten Bangkalan masuk klasifikasi rendah.

Abstract

The development of Padang City in the coastal area is potentially faced with seawater intrusion. This study was conducted to determine the characteristics of shallow groundwater on the coast of the city using stable oxygen -18 (18O) and hydrogen -2 (2H) or deuterium isotopes, which are abundant in the nature. The isotopic analysis revealed variations in groundwater isotopic composition, indicating the possibility of diverse recharge sources. Although this study was primarily focused on salinity identification, the isotopic data provided preliminary insights into the influence of local meteoric recharge. Water samples were taken at several locations 5 m below the ground surface, and one sample of seawater was collected at an elevation of 0 m, which comes directly from sea water. On the average, they were located 270 m from the sea. The spectrometry of these water samples produced isotope ratios expressed per thousand or mil, which were then plotted on a graph illustrating the relative abundances of oxygen (18O) and deuterium (2H). Analyses of the stable 18O and 2H isotopes found two water samples close to the local meteoric water line (LMWL) and one sample interacting or mixing with seawater. The mixing effect is likely the product of evaporation and interaction between water and oxide minerals that compose the aquifer lithology, i.e. loose (sand) deposits. Based on the electrical conductivity, these samples had brackish water.
