Abstract

Truncated spline nonparametric regression is a nonparametric regression analysis using a segmented polynomial model. This segmented nature provides flexibility so that the regression model can adapt more effectively to the local characteristics of the data. The purpose of this study was to obtain a regression model and determine the factors that influence the Human Development Index (HDI) in all provinces in Indonesia using multivariable truncated spline nonparametric regression. The Human Development Index is an important indicator in measuring success in efforts to build the quality of human life. The Human Development Index can determine the rank or level of development of a region and a country. In development, a high Human Development Index is something that is expected to be achieved, especially for developing countries. The Human Development Index data used in this study is based on BPS data published in 2020 from all provinces in Indonesia. In this study, based on the results of the analysis, the best nonparametric truncated spline regression was obtained using 1 knot point, 2 knot point and 3 knot point. Based on the minimum Generalized Cross Validation (GCV) value, the best truncated spline regression model is 3 knots with an R2 value of 83.70%. The factors that influence the Human Development Index are the variables expected length of schooling, life expectancy at birth, and population

Abstract

Children with intellectual disabilities who have limitations and deficiencies in terms of intelligence also have the right to receive education. One of the education provided to children with intellectual disabilities is in the form of a special self-development program with the aim of fostering children's independence. Moderate intellectual disabilities have limitations in the ability to care for themselves, take care of themselves, help themselves, life skills, etc. The research method in this study uses a descriptive qualitative approach research method, while the data collection process in this study uses observation, interview, and documentation techniques. This research was conducted on Monday, December 4, 2023 at 08.00 to 12.00 WIB. The location of the research was carried out at the SLB-E Negeri Pembina, North Sumatra Province, precisely in class XI-1C. The learning strategy for ABK with intellectual disabilities is of course we choose a learning strategy that suits them, because ABK with intellectual disabilities must carry out learning with an individual approach if now using the independent curriculum, actually ABK with intellectual disabilities have been independent learning for a long time. The direct introduction learning strategy for children with special needs and mental retardation is quite effective and can be used as an alternative for children with special needs and mental retardation in carrying out their learning activities.

Abstract

The agriculture and fisheries sectors are the 2 main sectors that support increasing food security in Indonesia. A new breakthrough that combines both sectors is the aquaponic cultivation system. This community service activity aims to utilize abandoned pools in the RT. 13, Damai Baru Village, Balikpapan, has become aquaponic cultivation to help the local community meet household food needs. The methods used are location surveys, problem identification, partner coordination, program outreach, creation of aquaponic cultivation ponds, and evaluation. The series of transformations carried out include designing, cleaning and increasing the size of the pool (length, width, and depth), adding a protective roof and hydroponic pipes, spreading fish seeds and water spinach, and educating on aquaponic maintenance. The resulting pond transformation has a size of 3.2 x 1.8 x 1.5 meters and 48 hydroponic planting holes. The aquaponic cultivation used is a combination of catfish and water spinach. Keywords: Aquaponics, Cultivation, Hydroponics, Catfish, Water Spinach

Abstract

Indeks pembangunan manusia (IPM) adalah indikator yang digunakan untuk mengukur kemajuan sosial dan ekonomi dalam suatu negara atau wilayah dengan fokus pada kesejahteraan manusia Penulis ingin melihat pengaruh dari variabel independen yaitu Angka Harapan Hidup (AHH), Harapan Lama Sekolah (HLS), dan Rata -rata Lama Sekolah (RLS) terhadap variabel dependen yaitu Indeks Pembangunan Manusia (IPM), dimana data diambil pada web BPS di 11 kabupaten/kota di Provinsi Jambi. Data yang diperoleh tersebut kemudian dianalisis menggunakan analisis regresi linier berganda pada software JASP. Langkah pertama dilakukan dengan mengetahui normalisasi data dari model regresi yang telah, kemudian melakukan uji asumsi klasik yaitu uji Multikolinearitas dan uji heteroskedastisitas. Pada uji multikolinearitas, hanya variabel X1 saja yang tidak multikolinearitas. Langkah selanjutnya yaitu melakukan uji F dan uji t dimana nilai signifikansi atau p-value nya < 0,05. Dari hasil penelitian tersebut diperoleh bahwa Angka Harapan Hidup, Harapan Lama Sekolah, dan Rata-rata Lama Sekolah memiliki pengaruh terhadap Indeks Pembangunan Manusia jika dipengaruhi secara bersama-sama (simultan). Angka Harapan Hidup juga bisa secara sendiri mempengaruhi Indeks Pembangunan Manusia, tetapi untuk Harapan Lama Sekolah dan Rata-rata Lama Sekolah tidak bisa mempengaruhi Indeks Pembangunan Manusia secara mandiri.

Abstract

The rapid development of digital technology has made the online exchange of personal data increasingly widespread, but on the other hand, it increases the risk of information leaks and misuse. Cases of personal data breaches in Indonesia demonstrate that weak security systems remain a potential avenue for cybercrime. One key solution to address this problem is the implementation of cryptographic systems. This study aims to analyze the role of cryptographic systems in maintaining the confidentiality, integrity, and authenticity of personal data as a foundation for information security in the digital era. The research method used is descriptive analysis, using a literature review approach of various scientific sources from 2021–2025. The results show that the application of cryptographic algorithms such as AES, RSA, and hybrid cryptography systems has proven effective in protecting data from unauthorized access and manipulation. Furthermore, the integration of cryptography with artificial intelligence and post-quantum cryptography technologies is a crucial innovation for strengthening information security systems in the future. This study concludes that cryptography is a fundamental element in personal data protection and is key to building a robust, efficient, and sustainable information security system amidst the increasing threat of global cybercrime.
