Abstrak: Keterbatasan akses terhadap pangan berpengaruh terhadap kualitas dan kuantitas konsumsi pangan rumah tangga. Penelitian ini bertujuan untuk menganalisis kualitas konsumsi pangan keluarga, kuantitas konsumsi zat gizi balita, pola asuh ibu, dan hubungannya dengan status gizi balita KPM PKH di Kecamatan Harau. Penelitian cross sectional study dilakukan pada bulan Maret hingga Juni 2021 pada 90 subjek. Data diperoleh dari hasil wawancara berdasarkan kuesioner, Food recall, dan HDDS. Subjek memiliki kualitas konsumsi yang tergolong tinggi (97,8%), tingkat kecukupan energi defisit (40,0%), tingkat kecukupan protein lebih (84,4%), Tingkat kecukupan zat besi (56,7%), vitamin A (98,9%), dan zinc (68,9%) cukup. Pola asuh ibu subjek tergolong baik (54,4%). Status gizi subjek yaitu berat badan normal (78,9%), tinggi normal (72,2%), gizi baik berdasarkan BB/TB (81,1%), dan gizi baik berdasarkan IMT/U (82,2%). Tidak terdapat hubungan yang signifikan antara pola asuh, kualitas konsumsi, dan kuantitas konsumsi dengan status gizi subjek (p>0,05)., Limited access to food affects the quality and quantity of household food consumption. This study aims to analyze the quality of family food consumption, quantity of nutritional consumption of children under five, mother's parenting, and its relationship with the nutritional status of toddlers from the family who get the benefit from family program of hope. in Harau District. The cross sectional study was conducted in March to June 2021 on 90 subjects. Data obtained from interviews based on questionnaires, Food recall, and HDDS. Subjects had a high quality of consumption (97.8%), a level of energy deficit adequacy (40.0%), an excess level of protein adequacy (84.4%), a sufficient level of iron (56.7%), vitamin A (98.9%), and zinc (68.9%) was sufficient. The subject's mother's parenting pattern is classified as good (54.4%).

Judul: The Relationship Food Consumption, Parenting Practice and Food Security with The Nutritional Status of Toddlers in Cianjur
Abstrak: Nutritional problems are a major problem in developing countries like Indonesia. Nutritional problems will impact the low quality of human resources (Bappenas RI 2020). WHO data states that there are 149.2 million children under five experiencing stunting and 45.5 million children experiencing wasting (WHO et al. 2021). The Indonesian Nutrition Status Study (SSGI) stated that the prevalence of wasting was 7.1%, underweight was 17.0%, and stunting was still very high at 24.4% (Ministry of Health RI 2021). One of the provinces with a high prevalence of nutritional problems in toddlers is West Java, where wasting in West Java 5.3%, while underweight 15.0% and stunting 24.5%. In Cianjur Regency, the prevalence of wasting was 2.9%, underweight was 14.1%, and the prevalence of stunting was quite high at 33.7%. In overcoming the problem of nutrition, Indonesia launched a program known as the National Movement to Accelerate Nutrition Improvement in the framework of the First Thousand Lives (1000 HPK Movement). Presidential Regulation number 42 of 2013 states that specific and sensitive interventions are needed to tackle the problem of malnutrition (Ministry of Health Regulation 2013). Even though there have been many programs by the government, until now, nutritional problems such as being underweight, wasting and stunting still have a fairly high prevalence. Many studies have been conducted regarding the factors that influence nutritional problems, but each study in a different location will produce different results. In theory, food safety and parenting style for toddlers will affect food consumption, which will ultimately have an impact on the nutritional status of toddlers. Based on this, researchers are interested in analysing the relationship between parenting, parenting food consumption, and food security with nutritional status in toddlers which, in theory, is a factor in the occurrence of nutritional problems. This study uses some data from a study entitled "Analysis of Household Socioeconomic and Gender-Based Determinants of Food and Nutrition Security in Rural and Urban Areas: A Study in West Java, East Kalimantan, Central Sulawesi and West Nusa Tenggara". The research was conducted in May-January 2023 in Cianjur Regency, West Java Province. This research has received Ethical Approval from the Research Ethics Commission involving Humans IPB University with No.78680/IT3.KEPMSM-IPB/SK/2022. The total subjects in this study were 91 toddlers aged 24-59 months. Respondents in this study were mothers of toddlers aged 24-59 months in Cianjur Regency. The inclusion criteria in the study were that the respondents were mothers of children under five aged 24-59 months in Cianjur Regency and were willing and ready to participate in this study using Indonesian. The data used in this research is primary data. Researchers collected the data through interviews using questionnaires and direct measurements. Data on subject characteristics collected through a questionnaire included age, gender, mother's education, mother's occupation, mother's level of knowledge related to nutrition, family socio-economic status, food security, parenting style and history of infectious diseases. Data on consumption patterns, including nutrient intake and food quality, were collected through questionnaires, 24-hour recall, Individual Dietary Diversity Score (IDDS), and Household Dietary Diversity Questionnaire (HDDS). Data related to food security consisting of food insecurity was

Judul: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
