Abstract

Practicum is one of the effective methods for students in learning Natural Sciences (IPA), especially Physics subjects. The purpose of the practicum is to make it easier for students to understand concepts and help explain physics concepts that cannot be observed directly by the eye. The 2013 curriculum demands physics learning to integrate various concepts, so that students have a thorough understanding of a phenomenon. This study aims to determine the effect of spring strain and tube length on the speed of propagation and wavelength. Ripple tank experiments that currently exist, only calculate variations in fluid height, gap size, vibrator frequency, and so on. The method used in this research is experimental, for the components used consist of a set of simple ripple tank tools and frequency sensors. The analytical technique used in this research is descriptive quantitative. The highest and lowest frequencies produced from the small tube were 20 Hz (l=70 cm; = 0.04 cm) and 1 Hz (l=5 cm; = 4.30 cm). The highest and lowest frequencies obtained from the large tube were 52 Hz (l=70 cm; = 0.05 cm) and 3 Hz (l=5 cm; = 4.95 cm). The highest and lowest wave propagation velocities produced by the small tube are 4.3 cm/s (l=5 cm) and 0.89 cm/s (l=70 cm). The highest and lowest wave propagation velocities produced by the large tube are 9.87 cm/s (l=5 cm) and 2.69 (l=70 cm). Based on the results of the study, it was shown that the greater the spring strain, the higher the frequency, the wavelength and the speed of wave propagation.©2019 JNSMR UIN Walisongo.

Abstract

Ketersediaan air tanah di Kelurahan Hargomulyo, Kapanewon Gedangsari, Kabupaten Gunung Kidul, D. I. Yogyakarta belum bisa mencukupi dengan banyaknya jumlah penduduk yang ada. Maka dari itu, dibutuhkan suatu studi pendugaan air tanah guna mendeteksi keberadaan lapisan air tanah (akuifer) di wilayah penelitian. Studi ini terlaksana pada tanggal 7 Agustus 2021 dengan titik ukur sebanyak 3 titik. Pendugaan kedalaman akuifer dalam studi ini memakai metode VES (Vertical Electrical Sounding) dengan menggunakan susunan elektroda Schlumberger. Metode VES adalah salah satu metode tahanan jenis yang bisa dimanfaatkan untuk pendugaan lapisan litologi bawah permukaan seperti lapisan akuifer. Pengambilan data lapangan VES dilakukan dengan memakai dua buah elektroda arus stainless steel dan elektroda potensial tembaga. Panjang bentangan pada tiap-tiap titik ukur, yaitu 400 meter. Data sounding tiap titik pengukuran diinterpretasi dengan memakai perangkat lunak HIRA, kemudian hasil interpretasi ditampilkan dalam bentuk log tahanan jenis dengan memperlihatkan nilai tahanan jenis, kedalaman, serta ketebalan tiap-tiap lapisan. Berdasarkan hasil pengolahan data diperoleh 10 hingga 12 lapisan batuan. Hasil analisis dari korelasi antar titik pengukuran dalam tiap lintasan memperlihatkan bahwa di daerah penelitian ada dua jenis akuifer, yaitu akuifer dangkal dan akuifer dalam. Akuifer dangkal ditemukan pada kedalaman 5-16 meter dengan nilai resistivitas berkisar antara 12,79 sampai 12,83 ohm.m, sedangkan akuifer dalam ditemukan pada kedalaman 22-85 meter dengan nilai resistivitas berkisar antara 10,56 sampai 16,85 ohm.m.

Abstract

Microtremor is ambient vibration on the surface ground by natural phenomena, human activities, etc. Microtremor data can be processed using various software such as Geopsy, easyHVSR, and MATLAB. Another alternative software to process microtremor data is Scilab. This research was conducted to classify the soil using HVSR methods on Scilab 6.1.0. in Sendangmulyo, Semarang. Data processing includes generating synthetic signals, coding the HVSR methods on Scilab, synthetic data testing, processing microtremor data, and mapping of natural frequency () and predominant period (). Coding tests are performed against synthetic signals and can display a pre-set .  from the HVSR spectrum then processed to get the . The  in Sendangmulyo, Semarang ranged from 1.280 Hz – 18.504 Hz, and the  ranged from 0.054 s – 0,781 s. Based on the  and , Sendangmulyo is composed of hard soil, medium soil, soft soil, and very soft soil.

Abstract

High blood sugar, cholesterol and uric acid are non-communicable diseases and are one of the causes of death in the world. Generally, this disease is very susceptible to be suffered by the elderly. One of the tests to monitor blood sugar, cholesterol, and uric acid levels is with an invasive disposable test kit. This method is inefficient because it causes the risk of infection, increases medical waste and is quite expensive. Real work students from Walisongo State Islamic University Semarang group 53 held a free examination in Krandon Village as an effort to carry out community service through appropriate technology in the health sector. Examination tools are made by lecturers and students using non-invasive methods (without injuring the body). Based on the results of student interviews with the community and health workers, this work program received a good response because the examination did not cause pain and helped reduce medical waste in the environment.
