Judul: Kontribusi Terigu terhadap Kecukupan Gizi Rumah Tangga Miskin di Wilayah DKI Jakarta
Abstrak: National Economic and Social Survey during the periode of 2002-2008 indicated the important of wheat flour as the second staple food after rice. Mandatory fortification of wheat flour was expected to improve the community nutritional status, especially poor households, but evaluation regarding the impact is remained limited. The aim of the study was to analize the contribution of wheat flour to the nutritional adequacy of poor households. This was a cross sectional study. The result of the study showed the wheat processing food that gave significant contribution to the wheat flour and micro nutrient intake were instant noodles, sweet breads, and fried foods. The average of wheat consumption among the sample households was 42.35 gram per capita per day that gave contribution to the adequacy of energy, protein, iron, zinc, vitamin B1, vitamin B2, and folic acid as follows; 7.7%, 7.2%, 3.4%, 2.9%, 4.1%, 2.7%, and 1.1%. Wheat flour fortification was expected to increase the contribution of micro nutrients iron, zinc, vitamin B1,vitamin B2, and folic acid as follows; 17.4%, 13.9%, 14.3%, 18.0%, and 24.5%.

Judul: Optimization of Food Consumption Among Low Income Households in DKI Jakarta
Abstrak: Rumah tangga miskin sebagai kelompok rentan gizi kurang dan rawan pangan perlu diupayakan untuk dapat memenuhi kecukupan gizi. Penelitian bertujuan mengevaluasi kualitas dan kuantitas konsumsi pangan dan mengembangkan model komposisi pangan yang dapat memenuhi kebutuhan gizi dengan biaya yang terjangkau bagi rumah tangga berpendapatan 20% terendah (kuintil 1). Penelitian ini menggunakan data sekunder Susenas 2021. Desain penelitian ini adalah studi deskriptif. Hasil penelitian menunjukan bahwa pangsa pengeluaran pangan rumah tangga menurun seiring dengan peningkatan kelas pendapatan. Tingkat kecukupan energi, protein, dan skor Pola Pangan Harapan (PPH) meningkat seiring dengan peningkatan kelas pendapatan. Rumah tangga kuintil 1 mengalami kerawanan pangan, defisit energi sedang, dan pola konsumsi kurang beragam. Model optimasi konsumsi pangan menggunakan pemrograman linier dan menghasilkan 4 model. Masing-masing model dapat mencukupi kebutuhan energi dan protein 90-110% AKG serta meningkatkan skor PPH antara 80-97 dengan biaya di bawah pengeluaran aktual yaitu Rp10.649,00-Rp15.756,00. Dengan pemilihan bahan pangan yang tepat dan menggunakan alokasi pengeluaran maksimal sama dengan pengeluaran pangan rumah tangga kuintil 1, kecukupan energi dan protein masih dapat dicapai serta skor PPH masih dapat ditingkatkan., Poor households as nutritional and food insecure groups need to be pursued to be able to meet nutritional adequacy. This study aims to evaluate the quality and quantity of food consumption and develop a recommendation model for food composition that can meet nutritional needs and affordable for households with the lowest 20% income class (quintile 1). This study used secondary data Susenas 2021. The design of this study is a descriptive study. The results showed that the share of household food expenditure decreased along with the increase in income class. The level of energy sufficiency, protein, and the Desirable Dietary Pattern (DDP) score increased along with the increase in income class. Households in quintile 1 had food insecurity, moderate energy deficit, and less diverse consumption patterns. The food consumption optimization model used linear programming and generated 4 models. Each model could fulfill the energy and protein needs of 90-110% RDA and increase the DDP score 80-97 with costs of Rp10.649,00-Rp15.756,00, which was below the actual expenditure. By selecting the right food and using the expenditure allocation maximum equal to quintile 1 household food expenditure, energy and protein adequacy can still be fulfilled and the DDP score can still be increased.

Judul: Hubungan Kekerabatan Undur-Undur laut (Hippa adactyla Fabricius, 1787) Berdasarkan Marka Gen 16S rRNA di Pantai Purworejo dan Bantul.
Abstrak: Kepastian spesies diperlukan sebagai dasar pengelolaan. Adanya fenomena cryptic species dapat menyebabkan kesalahan identifikasi spesies pada organisme akuatik secara morfologis. Penelitian ini bertujuan untuk memvalidasi spesies undur-undur laut (Hippa adactyla) secara genetik menggunakan marka gen 16S rRNA dan menganalisis hubungan kekerabatan undur-undur laut yang berasal dari pantai Purworejo dan Bantul. Proses isolasi dan ekstraksi DNA menggunakan kit Gene Aid lalu dihasilkan DNA total yang akan diamplifikasi dengan primer universal 16S rRNA dan selanjutnya disekuensing. Hasil identifikasi secara molekuler menggunakan BLASTn diketahui bahwa enam contoh undur-undur laut dari Purworejo dan Bantul memiliki kemiripan berkisar antara 99-100% dengan Hippa adactyla dari GenBank. Urutan basa nukleotida disejajarkan dengan outgroup dari genus Hippa, infraordo Anomura, dan ordo Decapoda menggunakan software MEGA 5.0. Hubungan kekerabatan antara Hippa adactyla yang berasal dari pantai Purworejo dan Bantul sangat dekat. Kajian ini menunjukkan bahwa gen 16S rRNA terbukti dapat dijadikan penanda yang akurat dan mampu memvalidasikan spesies Hippa adactyla.
