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

Sumber ADD berasal dari Anggaran Pendapatan dan Belanja Daerah. Tujuan pengalokasian tersebut sebagai pemerataan keuangan antar desa dan berkaitan dengan pendanaan kebutuhan desa sebagai penyelenggara pemerintahan dan pelaksana pembangunan masyarakat di desa. Tujuan riset menganalisis efektivitas dan efisiensi penggunaan ADD, adapun analisa yang dipakai dalam kajian ini adalah secara deskriptif. Desa “X†pemakaianya anggaranya telah secara efektif digunakan.Penggunaan anggaran tahun 2017 dan 2018 dikatakan efektif, namun efeknya karena muncul beberapa belanja tahun 2017 dan 2018 dan realisasi anggaran belanja sangat berbeda targetnya anggaranya. Kegiatan yang tidak terlaksana menjadikan anggaran tidak digunakan. Saat membuat anggaran, ada baiknya untuk mempertimbangkan kebutuhan Anda berdasarkan aktivitas yang Anda lakukan agar tidak terlalu banyak kesenjangan antara perencanaan dan pelaksanaan.

Liquid waste from the textile industry contains harmful dyes that can damage the environment. Pollution to the environment can be minimized by processing dye waste before being discharged into rivers or sewers. The dye waste treatment process can be carried out using the adsorption method. The adsorbent used was non-activated and acid-activated eucalyptus leaf waste (HCl 2 M). The solution used as adsorbate is malachite green. This study aims to optimize the absorbance level of eucalyptus (Melaleuca cajuputi) leaf waste against malachite green dye using the Langmuir adsorption isotherm method. The variables used are the mass variation of the adsorbent, the contact time and the adsorption isotherm model. The absorption efficiency value produced by the adsorbent of eucalyptus leaf waste with 2 M HCl activation was 87.4279%. Meanwhile, the non-activated adsorbent is 86.0290%. For time variations of 10 minutes, 15 minutes and 20 minutes on 2 M HCl activated adsorbent resulted in an absorbance of 0.026; 0.022; and 0.02. Based on the graph of the relationship between Ce and Ce/Qe for the non-activated adsorbent, R2 was obtained at 0.7039 while the 2 M HCl activation was 0.966. So, the eucalyptus leaf waste can be used as an adsorbent without a carbonization process, only needs to be given activation treatment using an acid solution.
