Judul: Development of Mackerel (Rastrelliger kanagurta) Nugget Products Substituted with Mackerel Fish Bone for Adolescence Girls
Abstrak: Nugget merupakan makanan olahan yang cukup digemari terutama pada remaja. Nugget berbahan ikan kembung dapat dijadikan alternatif makanan selingan yang dapat membantu menambah asupan zat gizi pada remaja putri. Tujuan penelitian ini adalah mengembangkan produk nugget ikan kembung dengan substitusi tulang ikan kembung sebagai pangan alternatif bagi remaja putri. Penelitian ini menggunakan tiga formula dengan persentase daging ikan kembung dan tulang ikan kembung yang berbeda yaitu F1 (100:0), F2 (90:10), dan F3 (80:20). Berdasarkan hasil uji organoleptik dan analisis zat gizi, formula nugget yang dipilih adalah formula nugget ikan dengan substitusi tulang ikan kembung sebesar 10%. Formula terpilih nugget ikan memiliki kadar air sebesar 50,05%; kadar abu sebesar 3,34%; lemak sebesar 2,41%; protein sebesar 12,03%; karbohidrat sebesar 32,16%; zat besi sebesar 5,46 mg/100 g; serta kalsium sebesar 211,25 mg/100 g. Nugget ikan kembung memiliki takaran saji sebesar 100 gram yang menyumbang energi sebesar 198 kkal. Produk nugget formula terpilih dapat menjadi makanan sumber protein, kalsium, dan zat besi berdasarkan ALG bagi kelompok umum.

Judul: Formulation of Chicken Nugget with the Substitution of Chicken Liver as a Product of High Iron and Vitamin A for Female Adolescent
Abstrak: Adolescent is an important growth phase where there is an increase of nutritional needs in order to support body growths and developments towards maturity. Anemia and vitamin A deficiency are two of nutritional problems that occur in female adolescent caused by inadequate intake of nutrients (both macros and micros). Chicken nugget with chicken liver substitution is an alternative snack that can help increase of iron and vitamin A intake in female teenagers. This study aims to develop a chicken nugget product with chicken liver substitution, and analyze it is nutritional contents. This study used four formulations with different ratios of chicken meat and chicken liver used, namely F0 (100:0), F1 (95:5), F2 (90:10), and F3 (85:15). Organoleptic, physical characteristics test, and nutritional analysis showed that F2 was the selected formula. This selected formula contains 56.8% moisture content, 1.46% ash content, 14.66% protein, 6.5% fat, 12.92% carbohydrate, 16.39 mg iron, and 760.16 RE vitamin A . One serving size of chicken liver nugget is equivalent to 4 pieces of nuggets and it contributes about 168 kcal of energy/day. The selected formula have met the requirements of nutritional claim for protein source, low fat, and high iron and vitamin A content., Remaja merupakan fase kehidupan yang penting dimana terjadi peningkatan kebutuhan gizi dalam rangka menunjang pertumbuhan dan perkembangan tubuh menuju kedewasaan. Anemia dan Kekurangan Vitamin A (KVA) merupakan dua masalah gizi yang terjadi pada remaja putri yang disebabkan oleh asupan zat gizi (baik makro maupun mikro) yang inadekuat. Naget ayam dengan substitusi hati ayam merupakan salah satu alternatif makanan selingan yang dapat membantu meningkatkan asupan zat besi dan vitamin A pada remaja putri. Penelitian ini bertujuan untuk mengembangan serta menganalisis kandungan gizi produk naget berbahan dasar hati ayam. Penelitian ini menggunakan empat formulasi dengan perbandingan daging ayam dan hati ayam yang berbeda, yakni F0 (100:0), F1 (95:5), F2 (90:10), dan F3 (85:15). Berdasarkan hasil uji organoleptik dan analisis kandungan gizi, F2 ditetapkan sebagai formula terpilih. Naget formulasi terpilih mengandung kadar air 56,8%, kadar abu 1,46%, protein 14,66%, lemak 6,5%, karbohidrat 12,92%, zat besi 16,39 mg, serta vitamin A 760,16 RE. Satu takaran saji naget hati ayam setara dengan 4 potong naget serta memberikan kontribusi 168 kkal dari energi sehari. Naget hati ayam formulasi terpilih memenuhi syarat klaim sebagai produk sumber protein, rendah lemak, serta tinggi zat besi dan vitamin A.

Judul: Utilization of terra/MODIS L1B data for analysis of horizontal wind profile in the troposphere
Abstrak: This study was concerned with horizontal wind derived from data collected with the Moderate-resolution Imaging Spectroradiometer (MODIS) on board the NASA’s Earth Observation System (EOS)-Terra satellite. The aim of this study is to develop a method for the estimation of horizontal wind movement in the troposphere based on Navier-Stokes equation. The method was applied to a calibrated and geolocated Terra/MODIS L1B 1 km data set. The data inputs to estimate surface temperature are retrieved from TIR (Thermal Infrared) bands 31 (10.780 μm to 11.280 μm) and 32 (11.770 μm to 12.270 μm). The obtained surface temperatures were later used to approximate geopotential height on a constant-pressure surface by using the modified Poisson equation. The main assumptions used are the hydrostatic equilibrium, ideal gas law, constant lapse rate and constant acceleration of gravity. Based on the distribution of geopotential height, the pressure gradient force is measured by the gradient of geopotential on an isobaric coordinate to present the horizontal wind profile. For certain topographic areas especially in the mountain ranges, there was a disadvantage of using pressure as a vertical coordinate which lead to inaccuracy. In spite of that, Terra/MODIS L1B data with 1 km spatial resolution can be used to estimate the horizontal wind movement in the troposphere.
