Abstract

We analyzed the seismic signals of the Mount Rinjani station to identify possible seismic anomalies before a series of major earthquakes on Lombok Island in 2018. We observe anomalies before earthquake events Mw >= 5.90. This research applies the detrended fluctuation analysis (DFA) method to investigate possible earthquake precursors associated with the analyzed earthquake. The results showed a relationship between scaling seismic signals (α) that exceeds the threshold of α values during the analysis period, and there is a deviation of the root mean square fluctuations in the corresponding scaling that should be rising but constant. The value of α with constant root mean square fluctuations occurs one to three days before the preliminary earthquake Mw 6.40 (28/07/2018) UTC and eight to 10 days before the main earthquake Mw 6.90 (05/08/2018). The Mw 6.90 earthquake had the most magnitude and could significantly contribute to the appearance of seismic anomalies.

Abstract

Online games are a worldwide achievement supported by technological advances that want the best for smartphone users. A weakness or failure in wireless communication is the propagation of the path used. Service providers or provaider have advantages and disadvantages. One of the things that makes it different is the weather conditions, normal weather conditions and rain. Special measurements in Ranked mode, which are carried out in the championship as a single target in order to be the winner, the stability of the connection is crucial to ensure that players can play without any network connection interruptions. This paper contributes to revealing the online game process by analyzing the performance performance of three internet providers (Telkomsel, XL, and Tri) in playing Mobile Legends: Bang Bang, especially in Ranked mode. Measurement using Mi-Fi with postpaid access (no quota restrictions) as an assumption of the same conditions for each provaider. Measurements are carried out using key parameters such as throughput, packet loss, and delay so that the results of the analysis are obtained using statistical methods to search for averages and variances. The results of the analysis from the calculation were obtained that Telkomsel outperformed XL and Tri.

Abstract

Keterbatasan pasokan listrik dan ketergantungan pada energi fosil menjadi permasalahan utama yang dihadapi masyarakat di Rumah Qur’an Sembalun. Kondisi ini mendorong perlunya pengembangan sumber energi alternatif yang ramah lingkungan dan berkelanjutan. Kegiatan pengabdian ini bertujuan untuk memanfaatkan biogas sebagai sumber energi listrik mandiri melalui penerapan sistem digester dan penampungan plastik berkapasitas 8 m³ yang terhubung dengan generator berkapasitas 700 watt. Metode pelaksanaan meliputi pengolahan limbah kotoran sapi dalam digester, penyaluran biogas ke penampungan, dan pengujian kinerja generator dalam menyalakan lampu LED hemat energi. Hasil pengujian menunjukkan bahwa sistem biogas mampu menghasilkan daya listrik antara 8 hingga 58 watt, dengan lama nyala total mencapai 60 menit. Daya rata-rata yang dihasilkan sebesar 15,28 watt dibandingkan daya nominal 15 watt, sehingga diperoleh efisiensi konversi energi sebesar 98,13%. Kegiatan ini membuktikan bahwa penerapan biogas berbasis penampungan plastik berkapasitas 8 m³ efektif untuk mendukung penerangan mandiri, sekaligus memberikan manfaat tambahan berupa pengelolaan limbah ternak dan pengurangan emisi gas rumah kaca, yang berkontribusi terhadap upaya kemandirian energi dan keberlanjutan lingkungan di wilayah pedesaan.
