Judul: Development of Sago (Metroxylon sp.) Muffin with Addition of Moringa Flour (Moringa oleifera L.) and Catfish Flour (Clarias gariepinus) for Female Adolescent
Abstrak: Anemia defisiensi besi yang dialami wanita di Indonesia, khususnya kalangan remaja, tergolong tinggi dengan prevalensi sebesar 27,2%. Konsumsi makanan dengan kandungan zat besi yang cukup dapat menjadi salah satu upaya untuk mengatasi anemia. Muffin merupakan salah satu jenis kue yang dikenal dan diminati masyarakat Indonesia pada berbagai kalangan. Penelitian ini bertujuan mengembangkan produk muffin dari tepung sagu (Metroxylon sp.), tepung kelor (Moringa oleifera L.), dan tepung ikan lele (Clarias gariepinus) sebagai makanan selingan yang berpotensi sebagai sumber zat besi untuk remaja putri. Penelitian dilakukan dari bulan Februari hingga April 2021. Taraf penggunaan tepung kelor dan tepung badan lele pada penelitian ini, antara lain F1 (30:20%), F2 (35:15%), dan F3 (40:10%). Hasil penelitian menunjukkan muffin dengan perbandingan tepung kelor dan tepung badan lele 30:20% (F1) merupakan formula terpilih. Kandungan energi muffin F1 per takaran saji memenuhi 10,4–10,7% kebutuhan energi remaja putri usia 13–18 tahun. Muffin F1 juga berpotensi sebagai sumber zat besi untuk remaja putri dengan kandungan zat besi sebesar 4,774 mg dalam 100 gram muffin., Iron deficiency anemia experienced by women in Indonesia, especially among adolescents, is relatively high with a prevalence of 27.2%. Consumption of foods with sufficient iron content can be an effort to overcome anemia. Muffins are one of the most popular cake in Indonesia. This study aims to develop muffins from sago flour (Metroxylon sp.), Moringa flour (Moringa oleifera L.), and catfish flour (Clarias gariepinus) as a potential iron-source snack for female adolescent. This study was conducted from February to April 2021. The ratio of Moringa flour to catfish body flour in this study were F1 (30:20%), F2 (35:15%), and F3 (40:10%). The results showed that muffin with the ratio of Moringa flour to catfish body flour 30:20% (F1) was chosen as the selected formula. The energy content of F1 muffin per serving is 10.4-10.7% of the energy needs of female adolescent aged 13-18 years. F1 muffin is also potential as an iron-source for female adolescent that contains 4.774 mg of iron in 100 grams of muffin.

Judul: Formulation of High Fiber Kepok Banana (Musa acuminata balbisiana C.) Muffin with Okara Flour Substitution
Abstrak: Muffin merupakan quick bread yang proses pembuatannya tidak memerlukan tahap fermentasi. Pada penelitian ini, muffin pisang kepok (Musa acuminata balbisiana C.) dengan substitusi tepung ampas tahu diharapkan dapat disukai oleh kelompok usia dewasa karena memiliki kandungan gizi yang baik khususnya kandungan serat pangan. Tujuan dari penelitian ini adalah untuk mengembangkan produk muffin pisang kepok (Musa acuminata balbisiana C.) tinggi serat pangan dengan substitusi tepung ampas tahu. Penelitian ini menggunakan rancangan acak lengkap dengan variasi tepung terigu dan tepung ampas tahu yaitu 100:0 (F0), 80:20 (F1), 70:30 (F2), dan 60:40 (F3). Analisis yang dilakukan dalam penelitian ini meliputi uji organoleptik, analisis kandungan zat gizi, dan analisis kandungan serat pangan. Hasil penelitian menunjukkan bahwa muffin formula terbaik adalah pada variasi tepung terigu dan tepung ampas tahu 80:20. Muffin formula terbaik mengandung kadar air 35,32%, kadar abu 1,85%, kadar lemak 12,17%, kadar protein 6,60%, kadar karbohidrat 44,06%, kadar serat pangan tidak larut 4,92%, kadar serat pangan larut 1,17%. Muffin formula terbaik sudah memenuhi syarat klaim kandungan zat gizi tinggi serat pangan untuk pangan olahan dengan kadar serat pangan total sebesar 6,1% dan dapat memenuhi 20,3% kebutuhan serat menurut Acuan Label Gizi (ALG) untuk kelompok umum., Muffin is a quick bread whose manufacturing process does not require fermentation stage. In this study, a high-fiber kepok banana muffin (Musa acuminata balbisiana C.) with okara flour substitution are expected to be liked by the adult age group because they have good nutritional content, especially dietary fiber content. This study aimed to develop a high-fiber kepok banana muffin (Musa acuminata balbisiana C.) with okara flour substitution. This research used a completely randomized design with variations of wheat flour and okara flour as much as 100:0 (F0), 80:20 (F1), 70:30 (F2), and 60:40 (F3). The analysis conducted in this study included organoleptic test, nutrient content analysis, and dietary fiber content analysis. The results showed that the best muffin formula was the 80:20 variation of wheat flour and okara flour. The best muffin formula contains 35.32% moisture content, 1.85% ash content, 12.17% fat content, 6.60% protein content, 44.06% carbohydrate content, 4.92% insoluble dietary fiber content, and 1.17% soluble dietary fiber content. The best muffin formula has met the requirements for high fiber food claims for processed food with a total dietary fiber content of 6.1% and can provide 22.3% of fiber needs based on the Nutrient Reference Values (NRVs) for general population.

Judul: Implementation of Spatio-Temporal Change Query in Relational Database.
Abstrak: Geographic object changes in various views. Object changes are recorded using a model of static storage. No historical connection between old version data and new version data has been built. For that, a storage model of spatio-temporal queries that can analyze spatio-temporal changes has been developed. The object changes the geometry are grouped according to the taxonomy of Spatio-Temporal Pattern Change. This research has been able to apply the query patterns change including born, expand, merge, contract, split, normal and die. This query based on geometric (area) changes. The implementation of spatio-temporal change queries represents an object changes continuously with easy, change detection is done by comparing two versions of data. Keyword: spatio-temporal change query, spatio-temporal change pattern.
