Kedua nilai signifikasi tersebut lebih besar dari taraf signifikan 0,05 sehingga dapat disimpulkan bahwa kedua kelas berdistribusi normal (Ho ditolak). Nilai signifikasi statistik pretest sebesar 0,0666. Sedangkan nilai signifikasi posttest sebesar 0,4311. Nilai signifikasi tersebut lebih besar dari taraf signifikasi 0,05, maka Ho ditolak yang berarti sampel berasal dari kelompok data yang homogennilai dari thitung adalah sebesar 3,250 sedangkan nilai dari ttabel pihak kanan adalah sebesar 1,695 dengan α :0,05 dan sampel sebanyak 32 . Berdasarkan hipotesis diambil kesimpulan bahwa Ha diterima dan Ho ditolak karena nilai dari thitung (3,250 ) ttabel (1,695) sehingga terdapat pengaruh pendekatan saintifik terhadap kemampuan berpkikir kreatif siswa secara signifikan.   Kata kunci : Saintifik, Berpikir Kreatif

The accident rate of building construction projects in Indonesia reached 9 cases out of a total of 48 cases (20%) from 2017 to 2022. Out of these, 43 cases were attributed to technical negligence, 4 cases were due to natural factors, and 1 case is currently under investigation. Given the issues related to construction accidents, this research aims to identify construction safety variables that are likely to occur and subsequently conduct a risk level analysis. The research methodology employed is a case study, followed by a risk analysis based on the Ministry of Public Works and Housing Regulation No. 10 of 2021 regarding the Guidelines for Construction Safety Management Systems. The research findings indicate that out of 34 construction safety risk variables, there were 2 hazards (5.88%) classified as high risk (B), 22 hazards (64.71%) classified as medium risk (S), and 10 hazards (29.41%) classified as low risk (K).

 Tulisan ini bertujuan menggambarkan bagaimana pengertian perencanaan, alas an perlunya perencanaan, proses perencanaan, hubungan perencanaan, dengan fungsi manajemen lainnya, cara mendapatkan keunggulan bersaing, jenis-jenis perencanaan dan manfaat perencanaan dalam ilmu pengantar manajemen. Perencanaan merupakan suatu proses yang tidak berakhir bila rencana tersebut telah ditetapkan, rencana harus dilaksanakan dan perencanaan harus mempertimbangkan kebutuhan fleksibilitas, agar mampu menyesuaikan diri dengan situasi dan kondisi baru secepat mungkin dan salah satu aspek penting perencanaan adalah membuat keputusan (decision making). Perencanaan dalam arti formal merupakan suatu proses yang melibatkan penentuan sasaran atau tujuan organisasi, menyusun strategi menyeluruh untuk mencapai sasaran yang ditetapkan dan mengembangkan hirarki rencana secara menyeluruh untuk mengintegrasikan dan mengkoordinasikan kegiatan. Kebutuhan perencanaan berlaku pada semua tingkat manajemen dan semakin tinggi tingkatannya, perencanaan mempunyai kemungkinan dampak paling besar atas keberhasilan organisasi. Para manjer tingkat atas sebagian besar waktunya digunakan untuk perencanaan masa depan dan strategis organisasi secara keseluruhan untuk mrekrut personalia, pengembangan teknik produksi, inovasi produk dan lain sebagainya. Manajer yang lebih rendah merencanakan untuk unitnya sendiri dan untuk jangka yang pendek. Oleh karena itu para manajer perlu memahami peran perencanaan jangka pendek dan jangka panjang dalam pola perencanaan secara keseluruhan. Jadi manajer puncak umumnya berkonsentrasi pada perencanaan jangka panjang dan setrategi organisasi, sedangkan manajer tingkat bawah berkonsentrasi pada rencana-rencana jangka pendek.

As Chat GPT rose to fame rapidly, it has drawn attention of researchers around the globe to conduct studies related to the use of Chat GPT in various sectors including education. This study aims to investigate the use of Chat GPT in ELT through reviewing numerous previous related journal articles. In this review study, the researchers collected thirty journal articles from several primary online databases, such as: ERIC, Google Scholar, Sage Pub, ProQuest, Elsevier, Academia, and Research Net. To analyze the data, the researchers performed a set of procedures, namely data selection, classification, analysis, and conclusion. The results indicate that Chat GPT is a powerful tool that potentially brings benefits yet it requires more consideration and caution to be properly and effectively implemented. In a nutshell, the role of human resources is required to remain dominant and Chat GPT is probably used as a supporting element in ELT. It is expected that this study provides fruitful insights that are highly beneficial to promote proper understanding and implementation of Chat GPT in ELT.

Purple sweet potato (Ipomoea batatas L.) is a tuber plant that has great potential in providing nutrients and energy sources for humans which is rich in carotenoids, vitamins, minerals, fiber and phytochemical compounds. The aim of this research is to analyze the content of carbohydrates, protein, fat, fiber, vitamins, minerals and other bioactive compounds in processed purple sweet potato foods. The data collection technique used is through an experimental-based qualitative approach, namely by conducting trials in the form of making a new product to become a snack called purple sweet potato balls containing chocolate which is then supported by primary and secondary data. The results obtained are that purple sweet potatoes have a lot of nutritional content consisting of 22.64% starch, fat (0.94%), protein (0.77%), fiber (3.00%), Vitamin C ( 21.43 mg/100 gr), and anthocyanins (110.51 mg/100 gr). So it can be concluded that purple sweet potatoes are useful in preventing heart disease, helping maintain body weight, preventing cancer, maintaining eye health, and minimizing the risk of inflammation.

Students’ ability to communicate their mathematical ideas in various ways is not as expected. It is difficult for teachers to improve students’ mathematical communication skills by improving learning styles, improving the learning atmosphere, and using appropriate learning models. Therefore, it is important to know the factors that influence students’ mathematical communication abilities. The aim of this research is to describe the factors that influence students’ mathematical communication skills. The subjects of this research were four children aged approximately 11 years who live in Hamparan Perak District. The data collection techniques used were observation and interviews. Data were analyzed using a qualitative approach. The results of the research show that the factors that influence students’ oral communication skills are study partners, self-confidence, shyness, nervousness, group learning atmosphere, learning time, and gender. Factors that influence students’ written communication skills include the inability to write down known information and be asked about it, lack of concentration in studying and inability to understand the content, as well as question difficulty, which includes the level of composure and composure in solving questions.

One of the primary school subjects that is compulsory for students to study is Natural Sciences (IPA). In conducting the learning process a teacher needs to prepare models and methods as well as what media is chosen to help the teacher deliver the material. So that students can receive the material well and work the matter properly and improve the student's learning outcomes from before learning to after learning. This research is to find out what models and media can be applied in IPA learning on simple aircraft material. This article is written using the research method of a library review. This research includes the study of libraries to gather information and analyze literature. Of the eight articles scanned with one or two using similar learning models and other learning media showed positive results for students and teachers. Improved student learning about simple aircraft material became better. Some models and learning media on simple aircraft material are a reference to teachers in implementing the IPA learning process well and achieving the entire learning plan.
