Volcanic eruptions pose a significant risk to communities located near active volcanoes. Disaster mitigation and risk reduction efforts rely on detecting and monitoring volcanic activity as early as possible. This article introduces VEVCC, a MATLAB-based application designed to precisely identify and extract volcanic seismic events from continuous data streams. VEVCC's primary objective is to facilitate the creation of an Excel file containing the arrival times of detected events, which can then be used for various purposes, such as early warning disaster mitigation and automated event identification via machine learning techniques. VEVCC utilizes cross-correlation algorithms to identify volcanic seismic events. It separates these events from background noise and other sources of seismicity, allowing for the construction of a clean and informative dataset. The extracted data is a valuable resource for estimating the frequency of volcanic events and evaluating patterns of volcanic activity. VEVCC's time-stamped event data is indispensable for improving early warning systems, real-time surveillance, and automated event identification. We tested the program on the Merapi volcano datasets during a 1998 campaign for a broadband experiment with the capability to extract the events automatically. Further machine-learning models and algorithms enhance the automatic recognition of volcanic events.

Land cover/land use is one of factors which is important in land management. The changes of land cover can affect on the polcy in an area. Land cover/land use of South Lampung Regency is potentially changes. Economy, social, and population are factors that affect the change in land cover.

Experimental cross sections for the He4(e,e′p)X reactions in the missing energy range from 0.017 to 0.022 GeV and up to a missing momentum of 0.632 GeV/c at xB=1.24 and Q2=2 (GeV/c)2 are reported. The data are compared to relativistic distorted-wave impulse approximation calculations for the He4(e,e′p)H3 channel. Significantly more events are observed for pm≥0.45 GeV/c than are predicted by the theoretical model, and striking fluctuations in the ratio of data to the theoretical model around pm=0.3GeV/c are possible signals of initial-state multinucleon correlations.

This article discusses the influence of learning support processes and resources in the knowledge of Chemical Laboratory skills of high school students in Ternate Island. The learning process of chemistry in high school especially on laboratory, related to time/schedule allocation, practical purpose and achievement indicator in skill area become the focus of discussion on this aspect. While the supporting resources of learning, more emphasized on aspects of facilities and infrastructure such as the availability of educators, laboratory buildings, tools and chemicals that are based on the value of accreditation Senior High School in Ternate Island. in this study using 3 methods of collecting data such as survey techniques in schools, interview with teachers in schools and tests students' lab skills. The results showed that the knowledge of high school students' lab skills on Ternate Island is getting higher in schools with better accreditation. Skill Knowledge of High School Students in Ternate Island is still in the low category on the glass organizing aspect at the laboratory.

Short-range correlations (SRCs) have been identified as being responsible for the high-momentum tail of the nucleon momentum distribution, n(k). Hard, short-range interactions of nucleon pairs generate the high-momentum tail and imprint a universal character on n(k) for all nuclei at large momentum. Triple coincidence experiments have shown a strong dominance of np pairs, but these measurements involve large final-state interactions. This paper presents the results from Jefferson Lab experiment E08014 which measured inclusive electron scattering cross section from Ca isotopes. By comparing the inclusive cross section from Ca48 to Ca40 in a kinematic region dominated by SRCs we provide a new way to study the isospin structure of SRCs.

Coffee is a drink favored by the broader community because of its distinctive taste. One of the kinds of coffee drinks consumed widely is instant ginger coffee. Ginger coffee has the advantage of natural antioxidant potential. It is necessary to innovate new products that are more practical and accepted by consumers and served with cold water, namely tablet effervescent drinks. The purpose of this research was to investigate the effect of the concentration of ginger-coffee powder and variations in the organic acid on the chemical and physical properties of effervescent tablets. The ginger-coffee powder was made by crystallization with a ratio of 1:1 of them. Tablet effervescent formulated with two kinds of acid, i.e., tartaric acid, malic acid, and a combination. The results showed that increasing ginger-coffee powder concentration significantly decreases moisture content, IC50, hardness, and lightness (L*). In contrast it significantly increased acid content, phenolic content, redness (a*), and yellowness (b*). Tablet with a combination of tartaric acid and malic acid has lower IC50, hardness, and lightness. In contrast, it has higher phenolic compounds, redness, and yellowness. The best formula formaking ginger-coffee effervescent tablets was a concentration of 50 % ginger-coffee powder with a combination of tartaric acid and malic acid.

Abstract Controlling the premature release of hydrophobic drugs like quercetin over physiological conditions remains a challenge motivating the development of smart and responsive drug carriers in recent years. This present work reported a surface modification of mesoporous silica nanoparticles (MSN) by a functional compound having both amines (as a positively charged group) and carboxylic (negatively charged group), namely 4-((2-aminoethyl)amino)-4-oxobut-2-enoic acid (AmEA) prepared via simple mechanochemistry approach. The impact of MSN surface modification on physical, textural, and morphological features was evaluated by TGA, N2 adsorption–desorption, PSA-zeta, SEM, and TEM. The BET surface area of AmEA-modified MSN (MSN-AmEA) was found to be 858.41 m2 g−1 with a pore size of 2.69 nm which could accommodate a high concentration of quercetin 118% higher than MSN. In addition, the colloidal stability of MSN-AmEA was greatly improved as indicated by high zeta potential especially at pH 4 compared to MSN. In contrast to MSN, MSN-AmEA has better in controlling quercetin release triggered by pH, thanks to the presence of the functional groups that have a pose-sensitive interaction hence it may fully control the quercetin release, as elaborated by the DFT study. Therefore, the controlled release of quercetin over MSN-AmEA verified its capability of acting as a smart drug delivery system.

Mechatronics is a multidisciplinary that includes a combination of mechanics, electronics, control systems, and computer science. The main objective of mechatronics learning is to establish a comprehensive mindset in the development of mechatronic systems. Project Based Learning (PBL) is an appropriate method for use in the learning process of mechatronic. The use of PBL by following the V model in system development process is expected to encourage the achievement of the main goal of learning in mechatronics lab. Demonstration of knowledge during the practical work done by drafting product development procedures documents, presentations, and project demo. The test result of mechatronics lab course based on PBL in Electronics Engineering Bandung State Polytechnic led to the conclusion that the model is acceptable and desirable to be passed with a few improvements. In addition, learners also feel there is a new challenge in following the PBL-based practicum.

Experimental cross sections for the $^4He(e,e'p)X$ reaction up to a missingmomentum of 0.632 GeV/$c$ at $x_B=1.24$ and $Q^2$=2(GeV/$c$)$^2$ are reported.The data are compared to Relativistic Distorted Wave ImpulseApproximation(RDWIA) calculations for $^4He(e,e'p)^3H$ channel. Significantlymore events in the triton mass region are measured for $p_{m}$$>$0.45 GeV/$c$than are predicted by the theoretical model, suggesting that the effects ofinitial-state multi-nucleon correlations are stronger than expected by theRDWIA model.
