Judul: Estimasi Sisa Nasi Konsumen di Beberapa Jenis Rumah Makan di Kota Bogor
Abstrak: Penelitian ini bertujuan untuk mengestimasi sisa nasi (setara beras) yang tidak terkonsumsi oleh konsumen di beberapa jenis rumah makan di Kota Bogor. Desain penelitian adalah cross sectional study. Kehilangan zat energi dari sisa nasi konsumen di rumah makan Sunda sebesar 8.3 kkal/kap/kali makan (0.4% terhadap AKE), dan untuk kehilangan zat protein sebesar 0.1 g/kap/kali makan (0.2% terhadap AKP). Sedangkan kehilangan zat energi dari sisa nasi konsumen di rumah makan Padang yaitu sebanyak 4.5 kkal/kap/kali makan (0.2% terhadap AKE) dan kehilangan protein sebanyak 0.05 g/kap/kali makan (0.1% terhadap AKP). Kehilangan zat energi dari sisa nasi konsumen di rumah makan Jawa yaitu sebesar 6.3 kkal/kap/kali makan (0.3% terhadap AKE) dan kehilangan protein sebanyak 0.07 g/kap/kali makan (0.2% terhadap AKP). Kehilangan zat energi di Warung Tenda yaitu sebesar 7.5 kkal/kap/kali makan (0.4% terhadap AKE) dan kehilangan protein sebanyak 0.09 g/kap/kali makan (0.2% terhadap AKP). Estimasi sisa nasi konsumen pada rumah makan Sunda yaitu sebesar 1.5 kg/kap/tahun. Pada rumah makan Padang yaitu sebesar 0.5 kg/kap/tahun. Estimasi sisa nasi per tahun pada rumah makan Jawa sebesar 1.0 kg/kap/tahun dan pada Warung Tenda yaitu sebesar 1.1 kg/kap/tahun. Kehilangan sisa nasi konsumen di rumah makan Sunda dengan cara penyajian nasi dalam bakul nasi belum dapat menekan kehilangan nasi dan menetapkan porsi ideal nasi.

Judul: Estimasi Sisa Lauk Hewani, Lauk Nabati, dan Sayuran Konsumen Beberapa Jenis Rumah Makan di Kota Bogor
Abstrak: This study aimed to estimate the waste of animal and plant sources of food, and vegetables among consumers of some type of restaurants in Bogor city. The study was conducted in Padang, Sundanese, Javanese Restaurants, and Tent Stalls. Data collection was conducted in March 2013 until April 2013. A cross-sectional design was implemented in this study. Total respondents were 279 consumers. Sundanese restaurants has a most variation types of plant sources and vegetables waste, and Javanese restaurants has a most variation types of animal sources waste. Gender is known to have tendency to be one the factors causing different leftovers, that female gave more leftover of animal sources, plant sources, and vegetables than male. Loss of nutrients due to waste of animal sources was the most in tent stalls. Loss of nutrients due to waste of plant sources and vegetables was the most in Javanese restaurants. However, generally, loss of nutrients percapita permeal of each foods is not significant, less than one percent of the RDA.

Judul: Penerapan teknik watermarking untuk penandaan hak cipta pada peta vektor dengan format DXF
Abstrak: Drawing Interchange Format (DXF) is one of the general file in the field of the vector image commonly used for making maps. The DXF format is a tagged data representation of all the information contained in an AutoCAD drawing (DWG) file. Tagged data means that each data element in the watermark is preceded by an integer number called the group code. The study was carried out because there is still no tools of labeling the copyright on digital mapping using DXF file. This study aims to generate an application for copyright labeling on vector map with DXF format that can be applied to any types of spatial objects in the map. The technique used is changing the code inside the vector image. The insertion of the watermark is done by utilizing ENTITIES section by multiplying objects for sets of binary values. The results showed that the image after the watermarking insertion process is the same as the original vector image. Embedded watermark is resistant to rotation and scaling, however it has the possibility of one-third to be broken in the attack on specific object. This study has successfully implemented watermarking technique for copyright labeling on the vector map with DXF format.
