Judul: Kadar Asam Lemak dan Kolesterol Kupang Merah (Musculista senhausia) Segar dan Rebus
Abstrak: Kupang merah (Musculista senhausia) consumed by many people of Surabaya area by boiling however information on the nutritional content changes due to processing kupang merah still a little. The purpose of this study was to determine the proximate , fatty acid and cholesterol of fresh and boiled kupang merah. The method used for proximate analysis by AOAC , fatty acids by GC, and cholesterol by Liebermann - Buchard . Fresh kupang has a moisture content 81.57% , ash 10.11% , 25.58% fat and protein 62.99%, while the boiled, water content is 75.48 % , ash 7.86% , 25.16% fat and protein 61.29%, fatty acids detected is SAFA 38.71% (fresh) and 37.31% (boiled), MUFA 8.13% (fresh) and 8.02% (boiled), PUFA 10.31% (fresh) and 8.77% (boiled), cholesterol content amounted to 102.57 mg/100 gram of fresh and boiled at 100.97 mg/100 gram . Boiling had a effect moisture content, ash, fat, protein, fatty acids and cholesterol.

Judul: Komposisi Kimia, Asam Amino, Mineral dan Residu Logam Berat (Hg, Pb) Kupang Merah (Musculista senhausia) Segar dan Rebus
Abstrak: The red kupang (Musculista senhausia) is that many bivalves living on the East Coast Surabaya, East Java. Processing is done by boiling. The purpose of this study was to determine the yield, chemical composition, amino acids, minerals, and heavy metal residues (Pb, Hg) fresh and boiled mussel. Analysis of chemical composition include moisture content, ash, protein, and fat. Amino acid analysis by HPLC, minerals and heavy metals by AAS and phosphorus by spectrophotometer. The yield of meat and the shells of mussels decreased after boiling. The chemical composition of mussels decreased after boiling water levels fell 6.09%, 2.25% ash, 1.39% protein, 0.42% fat, and carbohydrate increased 4.07%. Analysis of amino acids produces 9 essential amino acids and 8 non-essential amino acids in fresh and boiled mussels. Amino acids decreased after boiling. Analysis of macro minerals produce minerals (Ca, Mg, K, P, and Na) and micro minerals (Co, Cu, Fe, Mn, Se, and Zn) and heavy metal Hg and Pb in mussels fresh and boiled. Mineral Ca, Mg, K, P, Na, Cu down, while Co, Fe, Mn and Zn ride. Heavy metals Pb decreased, Hg and Se was not detected.

Judul: Penerbangan Otomatis Pesawat Tanpa Awak Jenis Sayap Tetap dengan iNav
Abstrak: Pesawat tanpa awak (UAV) dapat dikendalikan secara manual dengan remote control atau secara otomatis dengan flight controller (FC). Salah satu jenis UAV adalah sayap tetap yang memiliki bentuk seperti pesawat terbang pada umumnya. Penelitian ini bertujuan untuk melakukan penerbangan otomatis pada UAV jenis sayap tetap dengan mengkonfigurasi perangkat FC. UAV yang digunakan adalah model SkySurfer X8 dengan bentang sayap 1.4 m. FC yang digunakan adalah Matek F405-Wing yang dikonfigurasi dengan perangkat lunak iNav. Berdasarkan hasil uji terbang, UAV berhasil terbang secara otomatis mengikuti skenario yang diberikan. Skenario terjauh berupa persegi berukuran 600×600 m pada ketinggian 100 m, yang ditempuh dalam waktu sekitar 2 menit dengan kecepatan sekitar 65 km/jam. Diharapkan prosedur perakitan, konfigurasi, operasi, dan hasil data uji terbang dapat menjadi acuan dalam penelitian selanjutnya.
