Judul: The Effect of Economic Pressure and Quality of Life on The Quality of Family Care with Stunting Children
Abstrak: Indonesia saat ini masih dihadapkan permasalahan kesehatan, yaitu stunting. Kondisi tersebut dapat disebabkan oleh berbagai faktor baik secara langsung maupun tidak langsung. Faktor penyebab stunting secara tidak langsung menjadi perhatian bersama saat ini adalah kondisi keluarga baik itu secara ekonomi, sosial, hingga kualitas pengasuhan yang diberikan kepada anak. Tujuan dari peneilitian ini adalah untuk menganalisis pengaruh tekanan ekonomi dan kualitas hidup terhadap kualitas pengasuhan keluarga dengan anak stunting. Penelitian ini melibatkan 69 ibu dengan anak stunting. Lokasi penelitian berada di Kelurahan Bubulak, Kota Bogor, Jawa Barat. Pengambilan contoh menggunakan non-probability sampling dengan menggunakan teknik purposive sampling. Uji korelasi menunjukkan bahwa tekanan ekonomi memiliki hubungan negatif signifikan dengan kualitas hidup dan kualitas pengasuhan. Kualitas hidup berhubungan positif signifikan dengan kualitas pengasuhan. Hasil uji regresi menunjukkan bahwa usia anak dan kualitas hidup berpengaruh positif signifikan terhadap kualitas pengasuhan. Diperlukan kesadaran dan kerjasama berbagai pihak untuk memutus rantai malnutrisi antar generasi.

Judul: Effect of Food Consumption, Health, Education, and Economic Factors on Stunting in West Java
Abstrak: Stunting merupakan masalah gizi yang dialami oleh balita di Provinsi Jawa Barat dengan prevalensi sebesar 26,1%. Berdasarkan WHO conceptual framework, faktor penyebab stunting terbagi atas causes dan context. Penelitian ini bertujuan menganalisis konsumsi pangan sebagai cause, faktor kesehatan, pendidikan, dan ekonomi sebagai context serta pengaruhnya terhadap prevalensi stunting di Jawa Barat. Desain penelitian ini adalah ecological study menggunakan data sekunder yang dipublikasi pada tahun 2018-2019 dengan unit analisis 18 kabupaten dan 9 kota. Metode analisis yang digunakan adalah analisis deskriptif dan regresi data panel. Hasil penelitian menunjukan konsumsi pangan penduduk berupa tingkat kecukupan energi dan protein tergolong normal, namun skor Pola Pangan Harapan belum mencapai 100. Terjadi perkembangan pada faktor kesehatan meliputi usia harapan hidup, jumlah sarana, tenaga dan jaminan kesehatan, serta faktor pendidikan meliputi harapan lama sekolah, rata-rata lama sekolah, jumlah sarana dan tenaga pendidikan. Faktor ekonomi seperti skor Indeks Pembangunan Manusia, pengeluaran perkapita disesuaikan dan pengeluaran pangan mengalami perkembangan, sedangkan ketimpangan pendapatan dan persentase penduduk miskin mengalami penurunan. Hasil penelitian menunjukkan tingkat kecukupan energi, jumlah sarana kesehatan, dan indeks gini berpengaruh positif signifikan terhadap prevalensi stunting, sedangkan tingkat kecukupan protein, usia harapan hidup, jumlah tenaga dan jaminan kesehatan berpengaruh negatif signifikan terhadap prevalensi stunting di Provinsi Jawa Barat.

Stunting is a nutritional problem experienced by toddlers in West Java with prevalence of 26.1%. Based on WHO conceptual framework, the causes of stunting are divided into causes and context. This study aims to analyze food consumption as cause, health, education and economic factors as context and its influence on stunting prevalence in West Java. Design of this research is ecological study using secondary data published in 2018-2019. The analytical method is descriptive analysis and panel data regression. The results showed that energy and protein aduquacy level was normal, but Desirable Dietary Pattern Score had not yet reached 100. There were developments in health factors including life expectancy, personnel and health insurance, as well as educational factors including expected years school, mean years school, number of facilities and education personnel. Economic factors such as Human Development Index score, purchasing power parity and food expenditure have developed, while income inequality and the percentage of poor have decreased. The results showed that the energy adequacy level, number of health facilities, and Gini index had significant positive effect on stunting prevalence, while protein adequacy level, life expectancy, number of personnel and health insurance had significant negative effect on stunting prevalence in West Java.

Judul: Pengembangan Model Codebook untuk Identifikasi Chord Gitar
Abstrak: Acoustic guitar can produce sound waves with different types of tones. High-low tone is determined by the fundamental frequency of the sound wave. Human sense of hearing can distinguish high-and low tones, but can not know for sure what kind of tone is heard by him. This study developed a guitar chord recognition system. This study uses MFCC as feature extraction methods and the codebook as pattern recognition method for identification of the guitar chord. Cluster technique used in this study is the K-means clustering. Data obtained from MFCC are clustered using the K-Means method, and the model for classification is constructed using the codebook method. The parameters used in MFCC is the number of cepstral coefficients, overlap, and the time frame, while an important parameter in the K-Means is the number of clusters. This study uses 8640 guitar chord sounds from 24 classes. Each of the data is made up of two chords which will be tested. Simulation results show that the maximum accuracy obtained is 98.89% obtained on 26 cepstral coefficients, overlap 0.4, time frame is 30 ms, on 100 clusters.
