Judul: Pengembangan Aplikasi Web Antarmuka untuk IP Camera Berbasis Raspberry Pi dengan Metode Prototyping.
Abstrak: IP camera telah sangat luas digunakan dalam pemantauan hingga skala besar, seperti lalu lintas. Dibandingkan CCTV analog, IP camera memiliki kualitas gambar yang lebih baik yang sangat penting dalam pemantauan. Dalam penelitian ini, dikembangkan aplikasi IP camera berbasis web pada Raspberry Pi yang mudah digunakan, kualitas gambarnya bagus, dan harganya terjangkau. Metode pengembangan yang digunakan adalah prototyping. Prototipe aplikasi web yang dihasilkan telah memenuhi aspek dasar yang dibutuhkan oleh IP camera, seperti: menampilkan gambar pantauan saat ini, mengatur kualitas gambar, dan menyimpan rekaman gambar. Harga perangkat keras prototipe ini sekitar 600 ribu rupiah dengan resolusi kamera 5 MP. Oleh sebab itu, Raspberry Pi dapat digunakan sebagai basis untuk IP camera dengan harga terjangkau dan kualitas gambar yang tinggi.

Judul: Pembangunan Sistem Pemantauan Jarak Jauh Otomatis untuk Perilaku Ayam menggunakan Kamera Inframerah
Abstrak: Penelitian ini bertujuan untuk membangun sistem pemantauan otomatis jarak jauh menggunakan Raspberry Pi (RPi). Google Drive (GDrive) API digunakan sebagai metode transmisi data dan GDrive sebagai metode penyimpanan data. Sebuah livestream dari kandang ayam dapat diakses melalui halaman web dengan memanfaatkan ngrok sebagai tunneling software sehingga livestream dapat diakses secara publik menggunakan peramban web. Tiga resolusi video berukuran 640x480, 800x600, 1024x768 dengan masing-masing dua variasi framerate 15 dan 30 digunakan sebagai skenario pengujian perekaman video berdurasi lima menit sebanyak 12 kali untuk masing-masing resolusi dan framerate-nya. Skenario 640x480 dan 800x600 memiliki perbedaan peningkatan ukuran file sebesar 90% untuk 15 fps dan 85% untuk 30 fps, sedangkan peningkatan dari 800x600 ke 1024x768 relatif sangat tinggi yaitu sebesar 220~244% dan akan memakan banyak memori penyimpanan untuk perekaman jangka panjang., The purpose of this research is to develop an automatic remote monitoring system using Raspberry Pi (RPi), the RPi device is connected to Google Drive (GDrive) via GDrive API as the data transmission method for storing the recordings of chicken coop. A livestream of the chicken coop is accessible through a simple http web page utilizing ngrok as a tunneling software so that the livestream can be publicly accessed from anywhere using a web browser. The result of this research is an automatic remote monitoring system that can ease the process of remote monitoring broiler chickens and reduce production costs as well as recordings of the chickens that can be used for further research related to poultry behavior patterns. Three video resolutions of 640x480, 800x600, 1024x768 with 15 and 30 as the framerates each were used as test scenarios of 12 times five minutes recordings for each resolutions and framerates. The 640x480 and 800x600 scenarios showed an increasing difference of 90% for 15 fps and 85% for 30 fps, whereas the increase from 800x600 to 1024x768 showed a relatively high increase of 220~244% which will take a lot of memory space for long term monitoring.

Judul: Waxes, policosanols and aldehydes in sugarcane (Saccharum officinarum L.) and okinawan brown sugar (kokuto)
Abstrak: Waxes, long chain alcohols and aldehydes were found in several variants of sugarcane (Saccharum officinarum L.) and Kokuto, a non-centrifuged Okinawan cane brown sugar. Long chain alcohols, policosanols, have been reported to have beneficial effect to human health. The composition of wax in sugarcane was analyzed using HPLC with an evaporative light scattering detector. Sugarcane wax composed of 55–60% aldehydes, sterol esters and wax esters, 32–40% alcohols, and small amounts of triacylglycerols, acids and sterols. Extraction of policosanols performed effectively with hexane and methanol (20:1 v/v), while that of long chain aldehydes was with chloroform and methanol (2:1 v/v). Their composition was determined using GC with a flame ionization detector, whereas their compounds were identified using GC-MS. Sugarcane rinds contained up to 500 mg policosanols and 600 mg aldehydes per 100 g sample of Ni 22 cultivar. The content of policosanol and long chain aldehyde in Kokuto was influenced by its production systems. Compositional analysis of the end product confirmed the presence of policosanols and aldehydes up to 85 mg and 8 mg respectively per 100 g sample of Kokuto A, a product of brown sugar manufacture with open pan heating system. Octacosanol and octacosanal were found to be the major wax components in both sugarcane and Kokuto samples. This study revealed significant difference in content and composition of waxes, policosanols and long chain aldehydes between sugarcane parts, cultivars and harvesting times; also between Kokuto types and production methods.
