Judul: Kajian Kontribusi Pangan Terlupakan terhadap Pemenuhan Konsumsi di Daerah Rawan Pangan, Kabupaten Gunungkidul, Yogyakarta.
Abstrak: Forgotten foods didefinisikan sebagai pangan yang dahulu banyak dikonsumsi penduduk lokal, tetapi saat ini sudah mulai ditinggalkan. Penelitian ini bertujuan mengkaji kontribusi pangan terlupakan terhadap kecukupan konsumsi tingkat rumah tangga di daerah rawan pangan, Kabupaten Gunungkidul, Yogyakarta. Penelitian ini menggunakan data sekunder dari penelitian Palupi et al. (2020) mengenai Studi Rumah Tangga di Daerah Rawan Pangan, Gunungkidul, Yogyakarta. Peneliti sebelumnya menggunakan desain cross sectional study. Lokasi penelitian dilakukan di Desa Mertelu dan Desa Pucung, Kabupaten Gunungkidul, Yogyakarta dengan jumlah sampel masing-masing berjumlah 120 rumah tangga dari setiap desa. Tingkat pendidikan sebagian besar subjek berada di jenjang Sekolah Dasar (58%) dan memiliki pekerjaan petani dengan pendapatan tergolong hampir miskin (46%). Sebanyak 48% rumah tangga termasuk kategori rawan pangan, 39% kurang pangan, 8% rentan pangan, dan 5% tahan pangan. Sebagian besar ibu dan balita memiliki tingkat kecukupan defisit berat pada energi, protein, lemak, dan karbohidrat. Secara garis besar, tidak terdapat perbedaan pola konsumsi forgotten foods pada daerah pantai (Desa Pucung) dan pegunungan (Desa Mertelu). Frekuensi konsumsi forgotten foods berada pada kategori jarang (1-3x/minggu). Protein merupakan zat gizi yang menyumbang kontribusi terbesar pada seluruh kelompok forgotten foods. Akan tetapi, kontribusi forgotten foods terhadap kebutuhan energi dan zat gizi makro sehari terbilang sangat rendah.

Judul: Pola Konsumsi Pangan Dan Status Gizi Anak Balita Yang Tinggal Di Daerah Rawan Pangan Di Kabupaten Banjarnegara, Jawa Tengah
Abstrak: The most basic need for a human being for its survival is food. Food consumption pattern of under-five children influenced by food consumption pattern of adult. Consumption of food have a relationship with nutritional status of under-five children directly. Under-five children is one of vulnerable groups of nutritional problem. Banjarnegara District was the one of food insecurity area in Indonesia. Household level food insecurity is generally caused by lack of livelihood opportunities and high food prices. At the individual level, aspects like consumption level of food, food taboo, education, etc. can influence the levels of food insecurity. The aim of this study was understand the correlation of food consumption pattern, food taboo and nutritional status of under-five children of household in food insecurity area in Banjarnegara District, Central Java. A cross sectional study design was applied on this study. The locations were purposively selected at two sub districts such as Pejawaran Sub District and Punggelan Sub District, in Banjarnegara District. Sample was chosen with simple random sampling which consists of 300 household with children 2-5 years old. Data collected including : household characteristic, under-five children characteristic, food consumption pattern (level consumption and food frequency consumption), food taboo and nutritional status of under-five children. Descriptive analytic was carried to all variables followed by bivariate test using Spearman correlation. Measurement of household food security in this study used household overall energy intake. In correlated analysis, household characteristic (father educational level, mothers educational level, fathers job, mothers nutritional knowledge, expenditure allocation for food and non food) was significantly positive correlated with under-five children energy and protein consumption. Food taboo have no relationship with energy and protein consumption and nutritional status by any indicators weight/age, height/age and weight/height. Household characteristic was significantly positive correlated with nutritional status by any indicators weight/age, height/age and weight/height but not with energy and protein consumption.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
