Abstract

Angka Harapan Hidup (AHH) merupakan perkiraan usia hidup yang dapat dicapai oleh penduduk pada suatu wilayah. AHH merupakan salah satu indikator derajat kesehatan masyarakat suatu negara yang digunakan sebagai tolok ukur dalam mengevaluasi kinerja pemerintah di bidang kesehatan, lingkungan, dan sosial ekonomi. Salah satu faktor yang memengaruhi pencapain AHH adalah lokasi antar wilayah, sehingga dalam melakukan analisis perlu mempertimbangkan unsur lokasi di dalamnya. Penelitian ini bertujuan mengidentifikasi faktor-faktor yang berpengaruh signifikan terhadap AHH di 154 kabupaten/kota Pulau Sumatera dengan analisis regresi spasial pendekatan area dan mendapatkan model regresi spasial terbaik pada pemodelan AHH Pulau Sumatera. Regresi spasial merupakan analisis statistika untuk memodelkan dan mengevaluasi hubungan antara variabel dependen dan independen dengan memperhatikan keterkaitan unsur lokasi. Model regresi spasial pendekatan area SAR, SEM, dan SARMA dikaji dengan melibatkan 16 variabel independen terpilih dari 17 variabel independen yang teridentifikasi. Data bersumber dari BPS dan IPKM tahun 2018. Hasil penelitian menunjukkan, bahwa model SEM merupakan model regresi spasial pendekatan area terbaik dengan nilai  sebesar 58,23% dan nilai AIC sebesar 600,27. Variabel yang berpengaruh signifikan memengaruhi AHH Pulau Sumatera secara spasial, diantaranya yaitu proporsi balita gizi buruk dan kurang (X1), proporsi desa dengan kecukupan jumlah bidan per 1.000 penduduk (X7), proporsi rumah tangga dengan akses sanitasi (X9), persentase penduduk miskin (X13), angka buta huruf penduduk usia 15 tahun ke atas (X14), dan rata-rata lama sekolah (X15).Life expectancy is an estimate of the life span that can be achieved by residents in a region. Life expectancy is one of the indicators of a country’s public health degree that is used as a benchmark in evaluating government performance in the health, environmental, and socioeconomic fields. One of the factors that influence the achievement of life expectancy is the location between regions, so in conducting the analysis necessary to consider the element of location. This study aims to identify factors that have a significant effect on life expectancy in 154 districts/cities of Sumatra Island with spatial regression analysis of the area approach and to obtain the best model of spatial regression in the life expectancy modeling in Sumatra Island. Spatial regression is a statistical analysis to model and evaluate relationships between dependent variables and independent variables by paying attention to interrelations of location elements. The spatial regression model approaches the area of SAR, SEM, and SARMA reviewed with 16 independent variables selected from 17 identified independent variables. Data sourced from BPS and IPKM in 2018. The results show that the SEM model is the best spatial regression model for the area approach with a  value of 58.23% and an AIC value of 600.27. In term of spatial, variables that have a significant effect affect fife expectancy in Sumatra Island is the proportion of malnourished and undernourished toddlers (X1), the proportion of villages with the number of adequate of midwives per1,000 inhabitants (X7), the proportion of households with access to sanitation (X9), the percentage of population live in poverty (X13), the illiteracy rate of the population aged 15 years and over (X14), and the average length of schooling (X15).

Abstract

Rawan pangan merupakan isu global yang berkaitan dengan kesejahteraan masyarakat. Rawan pangan adalah kondisi dimana suatu individu atau rumah tangga tidak mampu memenuhi kebutuhan pangan yang cukup. Untuk mengatasi rawan pangan perlu diketahui karakteristik atau faktor-faktor penyebabnya. Program perlindungan sosial merupakan kebijakan yang memegang peran penting dalam upaya pemenuhan akses secara ekonomi bagi rumah tangga dalam upaya menurunkan kejadian rawan pangan. Penelitian ini bertujuan untuk mengetahui karakteristik rumah tangga rawan pangan berdasarkan status penerimaan program perlindungan sosial di Provinsi Aceh tahun 2020. Metode SMOTE CART dapat diterapkan untuk mencapai tujuan tersebut. Penerapan SMOTE terbukti mampu menyeimbang kelas data pada variabel status rawan pangan. Hasil yang diperoleh adalah BPNT dan PKH memberikan kontribusi paling besar dalam menentukan status kerawanan pangan dengan nilai AUC sebesar 0,61.

Abstract

Statistical technique used to analyze quality problems and improve process performance is Statistical Process Control (SPC). In this study, multivariate control chart is used to control the quality of the graduates of Statistics Study Program, FMIPA USK, namely using Multivariate Exponentially Weighted Moving Average (MEWMA) control chart to control process average, Multivariate Exponentially Weighted Moving Variance (MEWMV) to control process variability, and analysis Process Capability to assess the entire process. Data used is secondary data, namely GPA data, duration of thesis preparation, and length of study for graduates of Statistics Study Program, FMIPA USK in 2016-2021 as many as 122 people. Results of the study, using MEWMA control chart, it was found that the average process for quality of graduates was statistically controlled in phase II. Selection of the most optimal weighting is λ=0.9. Meanwhile, for application of the MEWMV control chart, it was found that the process variability in the quality of graduates was also statistically controlled. The selection of the most optimal weights is λ =0.9 and ω=0.3. The results of the calculation of process capability, multivariately the GPA variable, length of the final project preparation, and length of the study show that all three are not capable.

Abstract

This research focuses on the Generalized Structured Component Analysis (GSCA) method in evaluating service satisfaction at FMIPA Syiah Kuala University (USK).  FMIPA USK is expected to have good service quality to satisfy stakeholders with the services provided.  FMIPA USK needs to know the factors that affect service satisfaction.  An internal survey of the integrity zone is one way to determine the quality and satisfaction of the services provided by FMIPA USK.  However, this survey uses indirect variables, so the structural equation model (SEM) can be used.  The SEM method used in this study is component-based SEM, namely Generalized Structured Component Analysis (GSCA).  GSCA is used because questionnaires do not fulfill existing assumptions in general research, and the GSCA method does not require many assumptions.  This research aims to form a model, determine the relationship between indicators and latent variables, and know the relationship between latent variables and the factors significantly affecting student satisfaction with services at FMIPA USK.  The results of this study show that the indicators used are valid and reliable.  Reliability, assurance, empathy, and tangibles is a factor that affects service satisfaction.  Models formed in this study have a GFI value of 0.962 and SRMR of 0.365, so the model used is suitable.
