Judul: Kualitas Susu Segar sebagai Bahan Baku Keju Ditinjau dari Jumlah Sel Somatis, Kadar Lemak, dan Kadar Protein
Abstrak: The aim of this study was to observed quality of fresh milk reviewed by somatic cells count, fat and protein levels. This research was conducted in February 2011 to July 2012. There were 35 bulk milk were taken from six farms. Data were analyzed descriptively and using linear correlation. The highest number of somatic cell, fat, and protein 2 780 000.00 ± 1 146 423.01 cell/ml, 4.05 ± 0.34%, and 3.66 ± 0.28% respectively. The result showed that positive correlation between bulk milk somatic cells count with fat and protein levels from dairy farmers which suppliers of cheese industry.

Abstrak: Composition of fresh milk as cheese raw material determines quality of the cheese. The freshness of the milk should be guaranted and not falsified, according to SNI No. 01−3141 − 2011 about Fresh Milk. This study aims to examine the composition of fresh milk, freshness of milk, and falsification supposition of fresh milk were used as a cheese raw material in the milk processing industry. The milk composition test consist of specific gravity, fat content, solid content, solid-non-fat content, and protein content. Freshness of milk test were did by alcohol test, boiling test, and measurement of the degree of acidity (pH). Falsification supposition test were did by Storch test, carbonate test, coconut-milk test, and starch test. Data were analyzed descriptively and compared with SNI. Samples of milk were examined are incompatible with SNI as much as 94.28% for specific gravity, 37.14% for solid-non-fat content, 14.28% for protein content, and 2.86% for solid content, while the milk fat content entirely in accordance with SNI. In addition, it is known that as much as 17.14% of the sample did not have similar specified range of pH values on SNI and 17.14% of the sample were experiencing addition of cooked milk. Milk samples examined still can be used as raw material for cheese, but the cheese produced can undergo degradation.

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.
