AbstrakTelah dilakukan pengukuran resistivitas dan dielektrisitas tanah perkebunan Apel di Malang. Pengukuran resistivitas dilakukan dengan metode Geolistrik dan dielektrisitas dengan menggunakan Ground Penetrating Radar (GPR). Metode Geolistrik dilakukan dengan konfigurasi dipole-dipole dengan teknik sounding –mapping pada tiga lintasan area perkebunan seluas 1800 m2 dan satu lintasan pada area lapangan di sebelah perkebunan. Sementara itu, metode GPR diterapkan pada dua pohon apel untuk mengidentifikasi sistem perakaran apel. Pengukuran resistivitas dilakukan di perkebunan Apel desa Bengkaras Pujon, Malang sedangkan GPR dilakukan di perkebunan Poncokusumo Malang. Dari hasil pengolahan data resistivitas dengan menggunakan software Res2dinv diperoleh hasil nilai resistivitas dari keempat lintasan adalah: lintasan pertama 4,83 – 22094 Wm, lintasan kedua 6,69 – 4947 Wm, lintasan ketiga 14,1 – 178 Wm dan lintasan keempat 4,50 – 20025 Wm. Dari data tersebut secara keseluruhan belum dapat dibedakan dengan jelas nilai resistivitas antara daerah perkebunan dengan bukan perkebunan di lingkungan penelitian. Sementara itu dari pengukuran GPR diperoleh jangkauan pengukuran mencapai kedalaman 2,18 meter dan jangkauan kedalaman akar apel 1.9 meter. Rentang nilai konstanta dielektrik yang diperoleh 0,1 – 8,8 F/m. Nilai konstanta dielektrik akar 4,9 F/m. Kata kunci: Resistivitas, dielektrisitas, tanah, perkebunan apel AbstractThe resistivity and dielectric properties of Apple’s soil plantation area in Malang have been measured.  Resistivity measurement was done using geo-electrical methods and dielectric properties was measured using ground penetrating radar (GPR).

Abstract

Penggunaan gas di berbagai sendi kehidupan manusia sekarang ini tidak dapat terhindarkan, mulai dari kebutuhan skala rumah tangga hingga industri. Dalam upaya meningkatkan pencegahan terjadinya kecelakaan kerja akibat kebocoran gas, kontrol terhadap kebocoran gas merupakan sebuah tindakan yang vital. Oleh karena itu, makalah ini membahas respon sensor gas MQ2, MQ3, dan MQ5 terhadap gas dan asap. Ketiga sensor gas tersebut dijalankan oleh mikrokontroler ATMega328 dengan modul Arduino Uno. Sebagai aktuator, buzzer digunakan sebagai pengirim sinyal audio dan LED sebagai basis informasi visual terkait pengingat adanya gas berlebih yang terdeteksi oleh MQ2, MQ3, dan MQ5. Secara mekanisme fisis, ketika sensor gas mendeteksi adanya gas berlebih, maka sinyal suara dari buzzer akan aktif sedemikian rupa sehingga dapat digunakan sebagai indikasi dini terhadap keberadaan atau kebocoran gas. Secara umum, sensor gas MQ2, MQ3, dan MQ5 memiliki respon yang sedikit berbeda pada jenis asap dan gas yang berbeda. Pada gilirannya nanti, hasil dari penelitian ini dirancang sebagai informasi penting dalam pemilihan jenis sensor gas sesuai kebutuhan.  Simple Gas Leakage Detection System Based on Arduino UnoAbstractThe use of gas in various aspects of human life nowadays is inevitable, ranging from the needs of household scales to industries. As an effort to increase the prevention of occupational accidents due to gas leakage, control of gas leakage becomes a vital action. Therefore, this paper discusses the response of MQ2, MQ3, and MQ5 gas sensors to gases and smokes. The ATMega328 microcontroller ran the three gas sensors with the Arduino Uno module. As an actuator, buzzers were used as audio signal senders and LEDs as a basis for visual information related to reminders of excess gas detected by MQ2, MQ3, and MQ5. The physical mechanism, when the gas sensor detects the presence of excess gas, then the sound signal from the buzzer could be activated in such a way that it can be used as an early indication of the presence of leakage of gas. Generally, MQ2, MQ3, and MQ5 gas sensors performed slightly differently in responding to the presence of gases and smokes. In turn, the results of this study are designed as relevant information in selecting the type of gas sensor as needed.Keywords: Gas sensor, Microcontroller, MQ2, MQ3, MQ5, Simple instrumentation.

Abstract

Ultraviolet light is an electromagnetic radiation that has range of wavelengths between 100nm to 400nm. This wavelength can be identified by the ultraviolet index, where at this wavelenght ultraviolet light has an impact to human health. Ultraviolet light with ultraviolet index green to yellow is benefical for human health. Meanwhile, ultraviolet rays with red to purple ultraviolet index are harmful to human health. Ultraviolet rays that are harmful to humans can pass the surface of the earth caused by many factors, one of which is global warming. Therefore, this research was conducted to create an ultraviolet light detection system using Raspberry Pi as a sensor data reader and aims to learn about how much light reflected on the surface of the earth. The data obtained will be processed using the phyton programming language and presented using an LCD touchscreen. From this research, the values of the ultraviolet index from zero to six were obtained based on the ultraviolet index value from the BMKG indicate the categories of ultraviolet light associated with light reflection on the surface of the earth are known. So it can be concluded that the less ultraviolet light on the surface of the earth will be reflected easily by the earth, and the more ultraviolet light on the surface of the earth will be difficult to reflect.

Abstract

ABSTRAKDampak dari pendemi covid-19 memaksa setiap sekolah mewajibkan guru dan siswanya melakukan pembelajaran secara daring dari rumah. Hal tersebut membuat guru dan siswa dalam waktu yang singkat harus mempersiapkan seluruh vasilitas pendukung pembelajaran. Sedangkan di Kabupaten Malang, para guru fisika masih belum begitu akrab dengan pembelajaran daring, maka pendampingan dan pelatihan pembelajaran daring dengan memanfaatkan moodle sangat dibutuhkan. Kegiatan diawali dengan studi literatur dan lapangan, perencanaan, pemberian materi, demosntrasi dan praktek dan diakhiri dengan kegiatan evaluasi. Untuk mengetahui keberhasilan program, kami menyebarkan kueisioner (n = 13 item) kepada seluruh peserta tentang persepsi terhadap pembelajaran menggunakan moodle dan memantau perkembangan pemahaman guru melalui moodle yang telah dikembangkan. Guru fisika didampingi dan dilatih untuk membuat pembelajaran daring melalui moodle dan variasi model moodle yang sudah pernah diperoleh. Peserta pelatihan dan pendampingan yang diselenggarakan secara daring berjumlah 40 guru fisika di wilayah Kabupaten Malang yang meliputi 34 orang guru fisika SMA dan 6 orang guru fisika MA. Walaupun kehadiran guru tidak bersamaan masuk room meet, tetapi setiap guru selalu masuk setiap hari. Namun, yang aktif mengerjakan pembuatan moodle hanya 25 orang guru yaitu 24 orang guru SMA dan 1 orang guru MA. Peserta yang membuat moodle tersebut bervariasi ada yang hanya membuat Assignment untuk materi dinamika, sampai  ada yang lengkap membuat assignment, quiz, dan file untuk materi mekanika, dinamika, usaha dan energi, serta impuls dan momentum. Berdasarkan respon peserta pada angket terkait pelatihan dan pendampingan penyusunan moodle didapatkan 75,19% peserta merespon baik pembelajaran dengan moodle. Kata kunci: pelatihan-pendampingan; moodle; pandemi covid-19;  guru fisika.. ABSTRACTThe impact of covid-19 outbreaks forced every school to require teachers and students to do online learning from home.

Abstract

This paper learn programming of an Arduino. This also explores on how it can be used as a tool for study and research works. Learn how to program with Arduino, connect the project board to software on your computer, create sensor with the decision making and memory storing abilities of the Arduino. The ML8511 UV sensor outputs an analog signal in relation to the amount of UV light it detects and the effect to human body if get UV light in levels. The result are from three different locations, such as two outdoor and indoor start from 6.30 a.m until 10.45 a.m. Data shows that in outdoor during early morning or late afternoon hours the sun's rays pass at a greater angle through the atmosphere. Much more UV radiation is absorbed and less reaches the Earth, on the contrary in indoor UV index was 0. UV levels are highest under cloudless skies, and cloud cover generally reduces a person's exposure. However, light or thin clouds have little effect and may even enhance UV levels because of scattering. Don't be fooled by an overcast day or a cool breeze! Even a long stay in open shade, for example between buildings, may give a sensitive person a sunburn on a day with high UV levels. Therefore, it is important to know effect of ultraviolet’s level, from application of Arduino Programming using ML8511 UV sensor simplify the research.Keywords: Sensor UV; ML8511; Arduino; UV lights; Software.
