In this research, the water turbidity measurement tool based on Arduino Uno has been designed and built using phototransistors and infrared LEDs. This measuring instrument consists of a series of infrared sensors, Arduino as a process, LCD I2C as a value viewer, Micro SD as a data storage, and RTC as a timer. This study used two water samples with various concentrations. The sample used, namely distilled water plus impurities in the form of soil and ash. The distilled water used is still 100 ml with variations in the concentration of impurities ranging from 0,1-0,9 gr. Sensor test results show that the greater the turbidity level, the greater the voltage obtained. Sensor scanning ranges from 2,02 V-4,00 V for groundwater and 2,02 V-4,31 V for ash water. The reading uses a standard measuring instrument for groundwater ranging from 0 NTU to 331,4 NTU, while for ash water ranging from 0 NTU to 284,4 NTU. Data from the sensor test results in an equation used to convert the artificial measuring instrument's voltage value into a turbidity value. Then, data is taken using the same sample, so groundwater's turbidity value was obtained from 0 NTU to 318,94 NTU while for ash water from 0 NTU to 285,13 NTU. Based on the results, average accuracy for water was obtained. Soil amounted to 94,66%, while for ash water was 96,63%.

Hydrogen adsorption has been simulated on carbon nanotubes for optimum hydrogen absorption. Parameters that affect the amount of hydrogen absorbed have been studied, such as the effect of chirality and temperature on hydrogen absorption in CNTs. The simulation method of hydrogen adsorption on carbone nanotubes uses molecular dynamics simulation code LAMMPS, applies Lennard-Jones interatomic potential and hydrogen atom movement using Van Der Waals force with Microcanonical Ensemble. Data analysis is the output of LAMPS in the form of data in XYZ format. The data contains information in the form of integration steps, number of atoms, temperature, pressure, potential energy, kinetic energy, volume, van der Waals energy, total simulation time and hydrogen absorption. The simulation results show that the optimum absorption occurs at run 10000 and a temperature of 100 K, for armchair chirality of 10 atoms, chirality of 12 atoms and zigzag chrality of 5 atoms. Formation of hydrogen coordinates with Avogadro software, formation of CNT coordinates with VMD software and visualization of hydrogen adsorption on CNTs using VMD software.

SDN 1 Triharjo is committed to continuously improving student and school achievement, with a mission to create green and healthy schools. One of the standards that must be met to realize a green school is to take care of optical plants by making automatic plant sprinklers. School residents are still not aware of the importance of watering plants, because it will affect plant growth. Therefore, in this community service activity, assistance in the implementation of technology and internet of things (IoT) will be carried out for telegram-based plant watering automation. The direct involvement of teachers and students in implementing PkM activities is expected to increase the awareness of school residents to carry out environmental care behavior. The implementation of this activity is expected to be one of the added values for partner schools.

Di samping itu, kesempatan untuk mengikuti pelatihan keterampilan khusus laboratorium bagi guru IPA SMP/MTs masih minim. Tujuan kegiatan adalah untuk meningkatkan kompetensi keterampilan pengelola laboratorium IPA SMP/MTs di Kabupaten Lampung Timur. Metode kegiatan meliputi: tes awal, pemaparan materi (ceramah dan praktik yang diikuti peserta), dan tes akhir. Kegiatan dilaksanakan dua hari, yaitu tanggal 26—27 September 2019, di SMPN 1 Batanghari Kabupaten Lampung Timur. Jumlah peserta 48 orang guru, berasal dari 21 kecamatan di Kabupaten Lampung Timur. Hasil tes awal diperoleh nilai terendah 20, tertinggi 70, dan rata-rata 49. Pemberian materi dilaksanakan dengan metode ceramah, sedangkan pelatihan keterampilan peserta dibuat kelompok (satu kelompok terdiri atas 3—4 orang guru) dengan metode praktikum. Untuk mengetahui hasil pelatihan, di akhir kegiatan dilaksanakan tes. Hasil tes akhir diperoleh nilai terendah 50, tertinggi 90, dan rata-rata 69. Hal ini menunjukkan peningkatan komptensi dan keterampilan peserta yang ditunjukkan dengan peningkatan nilai tes. Materi tes berupa soal untuk mengetahui kompetensi dan keterampilan pengelolaan laboratorium.
