Judul: Pengaruh Kenaikan Harga Kedelai terhadap Profitabilitas dan Nilai Tambah Usaha Tahu Bandung Kayun-Yun di Desa Cihideung Hilir Kecamatan Ciampea Kabupaten Bogor
Abstrak: Small industries is part of SME (Small Medium Enterprise) sector that gives an important role in Indonesia’s economic development. One of small industry that potentially to be developed is soybean industries such as tofu industries. Soybean price increase that occurred in 2013 affects tofu small industrial especially Usaha tahu bandung Kayun-Yun. The purpose of this research was to analyze the effect of soybean price increase on profitability and added value of Usaha Tahu Bandung Kayun-Yun. Research location was selected with the considerations that Ciampea subdistricts is one of the all subdistricts in Bogor district that known as tofu production centers. The results showed after soybean prices increased, the total cost increased by 44 957 794 per month, sales volume is still in 6700 pieces per day, the difference in cost of production in the amount of Rp 206/piece for 4 cm tofu and Rp 254/piece for 5 cm tofu, break-even point in goods value for 4 cm tofu in the amount of 586 pieces with 175 873 rupiah IDR and for 5 cm in the amount of 330 pieces with 115 557 rupiah IDR. Profitability value showed an increase of 30.25 % for 4 cm and 29.36 % for 5 cm tofu. The result of the added value also increased by Rp 8 672/kg for 4 cm tofu and Rp 8 195/kilogram for 5 cm tofu.

Abstrak: Usaha Tahu Bandung Kayun-Yun is one of the small soybean industries that uses soybean as the main material. Soybean price increased that occured in 2013 involved the business interruption. The purpose of this research was to analyze feasibility of financial and non financial aspects. Data analysis methods used are qualitative and quantitative. Qualitative data used to analyze non financial aspects (market, technical, management and legal, social and economic, and enviromental aspects). While, quantitative data used to analyze financial aspects through four investment criteria, that is NPV, IRR, Net B/C and payback period. The value of NPV obtained at Rp 293 316 530, Net B/C obtained at 3.07, IRR obtained at 39 persen, and payback period obtained five year seven months seventeen days. The results is both of the financial and non financial aspects showed that Usaha Tahu Bandung Kayun-Yun is feasible to run, except the management aspects because the bussiness does not have financial record keeping and environmental aspects because waste water allowed to flow directly into the river so that in long impact can cause environmental pollution. Sensitivity analysis showed that soybean price increased is more sensitive variable than the decrease in number of production of tofu.

Judul: Categorization in Macaca fascicularis.
Abstrak: Categorization is an ability to group individuals or events into different classes mediated by conceptualized mental images. There are several levels of categorization and within a taxonomy the levels are nested. At the most concrete level of categorization, all or most members of the category shared common physical attributes that differ from other categories. The higher the level of category, the fewer common attributes between members of the group. In addition to humans, the ability to categorize has also been proposed in animals. One example of categorization in animal is species discrimination. Using matching-tosample task, present experiment tested ability of the long-tailed macaque (Macaca fascicularis) in discriminating dichotomous-stimuli of different animals. The species has been shown to be able to see photos as representations of real object so I used facial photos of humans and animals for the stimuli. First, I tested their ability to classify humans and macaques into separate group. Second, I tested their ability to discriminate their conspecific from other macaques. And the last, I tested whether the subjects were able to discriminate non-human animals from humans. In all of these experiments I found that the subjects showed high performance in categorizing objects, even when I discarded details of visual informations, such as color and local shapes. The ability to identify objects with reduced representation of physical properties means the subjects were able to generalize attributes of members of the group. This would indicate that the subjects created a higher level abstraction. On the other hand, in discriminating intrageneric macaque species I found that they were able to extract uniqueness of each species. More over, I also found that the subjects were able to put photos of non-human animals that shared very few similarities in physical percepts into one group. I suggested that the subjects could create a more abstract concept based on non-percepts relations as a basis to put the objects into one category. Thus, I concluded that M. fascicularis were able to perform multiple levels of categorizations.
