Abstract

Kondisi cuaca yang mudah berubah saat ini menyebabkan ketinggian gelombang di perairan Pulau Jawa Judul sulit untuk ditebak. Pulau Bawean adalah salah satu Pulau Kecil di tengah laut Jawa yang distribusi logistik dan aktivitas lainnya sangat dipengaruhi oleh kondisi laut Jawa. Sehingga diperlukan sebuah metode untuk mengidentifikasi model matematika ketinggian gelombang perairan Pulau Bawean agar dapat membantu instansi terkait dalam memprediksi ketinggian gelombang secara akurat. ARIMA merupakan salah satu metode dalam analisis data time series yang banyak digunakan untuk menganalisis data secara statistik untuk mendapatkan model terbaik berdasarkan perilaku data tersebut, salah satu diantaranya adalah data ketinggian gelombang. Dalam penelitian ini didapatkan bahwa ARIMA(2,1,0) merupakan model terbaik untuk ketinggian gelombang perairan Pulau Bawean.

Abstract

Numeracy ability is a basic ability that must be mastered by students especially elementary school students. Therefore, the purpose of this study is to improve the ability to count, add and subtract numbers 1-20 in slow learner students using ice cream stick media. This study uses quantitative experimental research on a single subject with an ABA design. The single subject in this study is a 1st grade student of SDN Tebul 1. There are 3 data collection methods used, namely interviews, observations and tests, while the data analysis uses visual analysis consisting of two types, namely in-condition analysis and inter-condition analysis. The results of this study concluded that ice cream stick media can improve numeracy skills in slow learner students. Based on the results of visual analysis, it was shown that in the initial baseline phase (A1) the ability to calculate the initial addition and subtraction of numbers 1-20 of slow learner students was still lacking with an average percentage of test results of 30%, after being given treatment in the intervention phase (B) by providing learning to count the addition and subtraction of numbers 1-20 using ice cream stick media, the numeracy ability of slow learner students increased by 45.33% with an average percentage of test results in the intervention phase (B) was 75.33% without overlapping data.

Abstract

In the constantly advancing era of digitalisation, ensuring cyber security has become essential in preserving the integrity, confidentiality, and accessibility of organisational data. The primary focus of this research is to emphasise the importance of cybersecurity awareness in safeguarding systems and information. The 1945 Constitution serves as the primary governing document for the government and legal system. The 1945 Constitution enacts legislation that ensures freedom of expression, a pertinent principle in cyber security. This research aimed to examine the role of security management in enhancing cyber security by applying principles in accordance with the 1945 Constitution. This research identified the factors affecting cyber security awareness and proposed strategies to enhance user awareness through a comprehensive literature review and examined recent findings. Security management is essential for guaranteeing the security of IT systems and infrastructure. Based on a literature review, this study determined the role of security management in assisting organisations in identifying, managing, and addressing security threats effectively. In addition, the hypothesised findings concluded that advancing cyber security in Indonesia is a fundamental aspect of state sovereignty, as stated in the 1945 Constitution and the principle of the Unitary State of the Republic of Indonesia (NKRI). These findings demonstrated the significance of comprehending cyber security for users and organisations and the necessity of international cooperation in the realm of national security in cyber. By gaining a more comprehensive comprehension of the function of security management, it is anticipated that organisations can enhance security protocols and mitigate security vulnerabilities as they confront the challenges of the present digital age.

Abstract

Penelitian ini memiliki tujuan untuk mengembangkan LKPD berbasis problem based learning untuk meningkatkan kemampuan pemecahan masalah pada materi barisan dan deret serta untuk mengetahui perbedaan rata-rata hasil belajar peserta didik sebelum dan sesudah diterapkannya LKPD berbasis problem based learning pada materi barisan dan deret. Jenis penelitian yang digunakan yakni penelitian dan pengembangan (Research and Development) dengan menggunakan model pengembangan 4D yang terdiri dari empat tahapan yakni Define, Design, Development, dan Dissemination. Namun, penelitian ini hanya sampai pada tahap Development karena penelitian ini terbatas pada uji laboratorium. Hasil uji kelayakan LKPD yang dikembangkan yakni untuk validasi ahli materi sebesar 93,85% (sangat layak) dan untuk validasi ahli media sebesar 96,67% (sangat layak). Hasil uji paired sample t-test yakni 0.000 < 0.05 yang artinya terdapat perbedaan rata-rata hasil belajar peserta didik sebelum dan sesudah diterapkannya LKPD berbasis problem based learning pada materi barisan dan deret. Dengan demikian, dapat disimpulkan bahwa LKPD yang dikembangkan telah dinyatakan sangat layak dan LKPD yang dikembangkan dapat meningkatkan meningkatkan kemampuan pemecahan masalah peserta didik.
