Abstract

Rumah Gadang is one of several traditional houses in Indonesia, precisely located in West Sumatra. Rumah Gadang is a residence for the Minangkabau tribe, which at present is almost extinct and has been replaced by modern houses that exist in this era while the remaining is used as a historical museum site of the Rumah Gadang and the function functions of each room that can be visited in certain areas. like Istano Basa Pagaruyuang, Batusangkar. In order for the knowledge of Rumah Gadang to be maintained until generations, there must be an effort to inherit architectural knowledge from the Rumah Gadang, both from the process of making the first milestone or commonly called the Tuo Milestone until later the end of the making of the Rumah Gadang. This paper aims to describe the process of building a Rumah Gadang so that its preservation can be maintained and to show the relationship between the architecture of Rumah Gadang and Science, so that it is related to the culture of Rumah Gadang and the existing science. And also its relation with other sciences such as social science for example in giving "kaba" or news, good or bad that will be conveyed to the public

Abstract

Soap is one of the essential needs in everyday life. A mixture of olive oil, virgin coconut oil (VCO), and palm oil can be processed into soap bars using the cold process method. This soap making process involves the saponification reaction of oils and fats with NaOH. Cooking oil, as one of the commonly used sources of fatty acids, also plays a role in soap making. This research aims to utilize natural ingredients such as palm oil, olive oil, and VCO (Virgin Coconut Oil) in the production of solid organic soap. In addition, this research also investigates the impact of adding coffee powder on the texture, color, and aroma of the soap produced. The main focus of this research was to create high-quality soaps from natural ingredients, especially coffee, with the aim of providing beauty benefits and improving skin smoothness. During the research, it was found that the soap hardens within 2 weeks, while the total saponification process time requires 4-6 weeks for the soap to be safe for use. The significance of this research lies in understanding the effect of the mixture of palm oil, olive oil, and VCO in making soap bars, as well as the effect of adding coffee powder extract. The results of the study are expected to provide in-depth insight into the optimal formulation to create quality solid organic soap.

Abstract

The development of the times requires every country to have rapid progress. Good education produces quality human resources. The influence of education plays a very important role in the human resources produced. Education continues to change according to the times. Innovation continues to be carried out in order to provide better quality education, both in learning models and learning strategies. Learning carried out by schools does not only focus on models but must choose the right strategy where students are trained to independently seek and find solutions to each problem found in learning. One strategy that can be applied in learning is problem solving learning strategies. Type of Quasi-Experimental research or quasi-experimental research. This Quasi Experimental Research aims to see whether or not there is an effect of giving certain treatments to the study group. The research design that will be used is a Pretest-Posttest control group design. The sampling technique uses purposive sampling. The sample consisted of an experimental class applying problem solving learning strategies and a control class applying conventional learning models. Based on hypothesis testing which has been carried out with the help of Microsoft Excel using the U test technique with a significance level of 5%. The obtained values ​​for are -4.67 and -1.96. Then H₁ is accepted and H₀ is rejected. Based on these data, it can be concluded that the use of problem solving learning strategies influences the learning outcomes of students at SMP Negeri 15 Padang City.

Abstract

Indonesia has high biodiversity. One of the efforts in managing biological resources is to use a local wisdom approach. the tingkeban traditional ceremony is one of the products of local wisdom in the Madiun. The tingkeban or mitoni tradition is a ceremony which is performed when you are seven months pregnant. During the ceremony, pregnant women and their husbands are bathed in water from the setaman flower accompanied by special mantras and prayers according to their respective beliefs. The tingkeban ritual in madiun is a form of communication, because it represents community participation, togetherness, mutual cooperation, hospitality, and interaction. The tingkeban tradition in Madiun has characteristics that are different from other tingkeban traditions.

Abstract

Penelitian bertujuan untuk mengidentifikasi dan melihat kebutuhan siswa terhadap bahan ajar berbasis aplikasi Android terintegrasi untuk mitigasi bencana. Metode deskriptif dalam penelitian digunakan dengan pendekatan kuantitatif dan kualitatif. Sampel dalam penelitian ini adalah satu orang guru IPA yang mengajar di kelas VII dan 31 siswa yang diambil secara acak (random sampling) di SMP N 32 Padang. Hasil penelitian ini adalah (1) Media pembelajaran yang digunakan guru kurang maksimal, sehingga perlu adanya media pembelajaran yang dapat membuat proses belajar mengajar lebih efektif dan efisien serta dapat terjalin hubungan yang baik antara guru dan siswa. , (2) Perlu menggunakan media pembelajaran berupa buku digital. untuk diterapkan dalam pembelajaran IPA, (3) Pembelajaran dari kehidupan sehari-hari melalui pendidikan mitigasi bencana perlu diterapkan, karena dapat meningkatkan kesadaran dan dapat meningkatkan kewaspadaan siswa mengenai penanggulangan bencana sejak dini, dan (4) Media pembelajaran IPA dapat diperkuat dengan muatan kebencanaan sebagai upaya menyebarkan pesan mitigasi bencana, agar tercipta karakter kesiapsiagaan menghadapi bencana, karena siswa masih minim pengetahuan tentang mitigasi bencana. Kesimpulan dari penelitian ini adalah bahan ajar berbasis aplikasi Android yang terintegrasi dengan mitigasi bencana diperlukan untuk memaksimalkan proses pembelajaran dan dapat mengasah kesiapsiagaan siswa dalam mengatasi bencana.

Abstract

Based on preliminary studies, the interview that has been done to teachers and students, it was found that the learning process still needs to be optimized because the learning was still centered on the teacher and students were not actively involved in the learning process. From the initial studies through interviews and questionnaires to science teachers and students at SMP 2 Portibi, it was found that science teachers had not used the STEM approach worksheet teaching materials and some students still having difficulty understanding the matter of substance pressure and its application. This type of research is Research and Development (R&D) using the 4D model which consists of four stages: define, design, develop, and disseminate. Based on data analysis, it was found that the validity and practicality values ​​of the product with an average validity of 0,52 were in the medium category and the average practicality according to the teacher and students respectively was 0,97 and students 0,93 were in the very high category.

Abstract

Soap, as a cleaning agent, is produced through a saponification reaction between oil and a strong base (NaOH), producing glycerol as a by-product. In this case, experiments were carried out using the cold process method to explore making soap with the addition of papaya extract. This research also involves analyzing the quality of soap through organoleptic tests and acidity degree (pH) analysis. The organoleptic test results showed that the soap had an appropriate texture, sufficient foam, and an attractive color after dyeing. Implementation of the saponification reaction with NaOH requires precision and accuracy of measurements for the success of the process. Apart from that, the use of essential oils and the proportion of NaOH affect the quality of the soap. The curing process is carried out for ± 30 days to optimize the quality of the soap. This research aims to produce good quality soap, with a focus on evaluating organoleptic tests and acidity levels as indicators of success.
