Abstract

Morals are very important, so Allah SWT sent his messenger to fix it. Morals, attitude and character positive are life skills. Life skills cannot be taught, they should be transmitted, so a model is needed to be imitated. Scientific phenomena have the potential to be a model. Nature saves a lot of messages from Allah SWT which, if digested, becomes knowledge. One of the scientific phenomena in nature that can be used as knowledge and improve life skills are butterflies and magnets. Literature study is used to analyze scientific phenomena from several aspects, namely 1) religion based on Al-Quran and Hadith, 2) scientific concepts of phenomena found in nature, 3) application in life, and 4) integration in life skills. Butterflies can be a model of the importance of self-control to be good and not give up quickly in the face of difficulties and the belief that with difficulties there is ease. Magnets become a model of unity, rhythm, agreement, strength will be achieved. Based on the analysis, it can be concluded that the creation of Allah SWT in nature in the form of scientific phenomena can be a model for improving life skills.

Abstract

The increase in the incidence of disasters in recent years has given birth to many ideas in disaster mitigation efforts to save lives from the effects of disasters. The disaster mitigation system in Indonesia is still far from ideal. Mitigation technology is only limited to pre-disaster and early warning. There is no technology that facilitates knowledge and preparedness. Education and disaster mitigation procedures that must be imitated by the community are very necessary. The aim of the study was to determine the effectiveness of the disaster mitigation learning model on disaster awareness of students at SD N 6 Mataram. This study was limited to 25 fifth grade or high grade students at SD N 6 Mataram using a one group pretest-posttest design. Disaster mitigation awareness is measured using an objective test instrument with 25 items. Disaster mitigation awareness includes disaster knowledge (PK), disaster signs (TB), risk impact and efforts to reduce (DR), preparedness (KN), and procedures, first aid tools for victims (AP). The disaster mitigation awareness test instrument used has been tested for validity and reliability. The data obtained were statistically analyzed using SPSS 23.0 by performing normality test and paired t-test (paired t-test). The results showed that the student-oriented disaster mitigation learning model was effective in increasing the disaster awareness of students at SD N 6 Mataram.

Abstract

Tapes, radio, laudspeakers, TV, and VCDs are all sources of organized and controlled sound. However, if this regular and controlled sound emits a sound that exceeds the desired sound level threshold and declared as noise that causes disturbances to human health, especially the sense of hearing. Hearing apparatus, namely the ear functions as a phonoreceptor capable of responding to sounds in the range 0 - 75 dB without causing pain. The frequency to which the human ear can respond is between 20 - 20,000 Hz and is very sensitive to frequencies between 1000 Hz - 4000 Hz. This study aims to determine how much the measured sound intensity level of the music sound at the Sinta Pub Maumere Bar and determine the degree of music sound intensity level at the Sinta Pub Maumere Bar at the measuring point of the sound source. This research was conducted at the Sinta Pub Maumere Bar using observation and experimental methods. The results showed the measured level of music sound intensity ranged from 103.12 dB. The highest level of sound produced is 110.6 dB and the lowest music sound intensity level produced is 92.4 dB. Based on the measurement results, the music sound intensity level at the Sinta Pub Maumere Bar has a different value. This shows that there is a difference measuring levelat the position of the distance from the sound source to the intensity level of the resulting music sound.

Abstract

Basic literacy is one of the competencies that must be possessed by 21st century students. The basic literacy of students is still relatively low, so the government makes various efforts to improve literacy, one of which is through the Independent Learning-Independent Campus (MBKM) policy, namely the Teaching Campus. The purpose of this study was to improve 5 aspects of student literacy at SMP Negeri 19 Mataram through the Teaching Campus Program Batch 2 in 2021. The aspects studied consisted of literacy, numerization, science, digital, and culture and citizenship. Each aspect of literacy has certain indicators. The research was carried out from August to December 2021 with a total of 20 students. The assessment of each indicator for each aspect of literacy uses a scale of 4, and is converted in percentage form with ratings of Less (K), Enough (C), Good (B), and Very Good (A). The increase in literacy scores was calculated using N-gain with three criteria, namely Low, Medium, and High. The results showed that the lowest literacy aspect was digital literacy while the highest literacy was scientific literacy. The average literacy value during the initial assessment was 51.6 with a rating of Less (K), while at the final assessment it was 82.0 with a rating of Good (B). The N-gain value was obtained at 63.1 which was in the Medium criteria. Thus, it can be concluded that the Teaching Campus Program Batch 2 in 2021 has improved 5 aspects of student literacy at SMP Negeri 19 Mataram.
