Abstract

The presence of the Indo-Australian plate, the Eurasian plate and the active Sumatra fault zone makes the West Sumatra region and its surroundings have very high seismic activity. To describe the seismicity pattern, it is necessary to analyze the earthquake hypocenter relocation, one of which is using the double difference (hypoDD) method. This method basically uses the data residual travel time from each hypocenter pair to the earthquake seismic station. The purpose of this research is to analyze the relocation of the hypocenter and describe the seismicity pattern in the West Sumatra and surrounding areas. The data used in this study are the time arrivals of P and S waves during the period of  2022 obtained from the earthquake catalog at the Padang Panjang Geophysical Station. The results showed that the earthquake hypocenter was relocated 888 out of 934 earthquake events and the distribution of hypocenter relocation produces a good seismicity pattern. From the results of the earthquake hypocenter relocation, the seismicity pattern in the West Sumatra region and its surroundings is generally influenced by subduction zones and some due to active fault zones. Seismicity in the subduction zone and active faults of Sumatra has a depth of about 50 - 250 km and 5 - 20 km. This indicates that during the period of 2022, subduction zones with medium to deep depths are very active as well as in Sumatra's active fault zones, especially  in the Sianok segment.

Abstract

Increasing the productivity of soybean plants using environmentally friendly techniques is urgently needed. This study aimed to determine the magnetic field (MF) treatment time that can optimize soybean growth and productivity. This study used soybean seed samples of the Grobogan variety. The seeds were obtained from the Research Institute for Various Nuts and Roots-Indonesia. The treatment was performed using MF of 0.3 mT, with treatment times varying from 0 to 30 minutes. Each treatment group was repeated once a day for five days. This study obtained the results that the time of MF treatment affected the sprouts' emergence time, plant growth, fruiting time, seed weight, and production per plant. Optimal results were obtained from seeds treated with a MF for 20 minutes. Treatment with time-varying MF requires lower magnetic flux density (MFD) and treatment time than stationary MF. Treatment time that is too long can reduce germination, plant growth, and soybean productivity

Abstract

This research was conducted in the library of the health center at Posyandu (Integrated Service Post) located in Pasar Borbor Village. Research is carried out once a month in the second week with routine activities for the community. Geographically, Posyandu is far from residential areas, difficult for the community to reach, so there has been a decrease in visits from mothers with toddlers. The purpose of this study was to analyze "Implementation of community education and knowledge development in the utilization of digital literacy in the library of the Borbor Sub-District Public Health Center". The research method used is a descriptive qualitative research method. The population in the study were mothers who had 91 children under five, 41 of whom were samples taken using the accidental sampling technique. To obtain data in assessing knowledge and compliance is done by using a data collection instrument in the form of a questionnaire. The data obtained was then analyzed using the Chi Square statistical test with a value of α = 0.05. The research results obtained show: 1) the majority of the utilization of digital literacy is ± 43.9%, and does not utilize digital literacy of 56.1%; 2) Lack of knowledge of mothers under five is the main reason for not utilizing digital literacy when visiting posyandu, 3) There is a relationship between knowledge and utilization of digital literacy during visits (p=0.000), 4). Mothers of toddlers who have good education and knowledge make more use of digital literacy to make visits to posyandu compared to those who have less education and knowledge. The results of the research really hope that the community will take advantage of digital literacy in visiting the nearest Posyandu

Abstract

Less varied learning method result in low scientific literacy of students. This study aims to determine whether the application of lesson study in learning can improve students' scientific literacy skills in the Respiratory System material. This research is action research carried out at SMA Negeri 1 Lohbener. The subjects in this study were students of class XI IPA 1 with a total sample of 22 people. The instrument used in this study was HOTs-based literacy question sheets which were given in each cycle to measure students' scientific literacy improvement. The results of data processing obtained an average score of scientific literacy skills in cycle I of 53.0 with a percentage of 53% and in the very low category, the average score in cycle II of 57.0 with a percentage of 57% and in the low category, and the average score in cycle III of 67.0 with a percentage of 67% and in the moderate category. The main factor causing an increase in students' scientific literacy skills only reaching the moderate category was students who were not used to answering HOTs-based literacy questions and were used to answering LOTs-type questions, so they experienced difficulties in doing the formative tests given. Even so, the application of lesson study in learning material on the respiratory system is proven to be able to improve students' scientific literacy skills at each level. Based on the results of observations of teachers and students during the implementation of cycle actions, it appears that the implementation of actions has reached the predetermined performance indicators

Abstract

The aim of this study was to determine the effect of the intensity of the yellow LED light and the sound intensity of religious music (Asmaul Husna) on the growth of various types of chili plants in indoor system. The research method uses experimental research. This research was conducted in Baitussalam District, Aceh Province. This research was conducted for a month. Based on the results and discussion, it can be concluded that exposure to LED lights and religious music (Asmaul Husna) has a fairly good effect on the growth of stem height, number of leaves and leaf width of the three types of chili plants tested. This is because the addition of light in the form of LEDs and sound can help the plant photosynthesis process to be more productive and accelerate the growth of the third type of chili. From the three types of chili, the most significant effect is in terms of plant height, leaf width and number of leaves found in chili peppers compared to the results obtained on cayenne pepper and green chili.
