Ilmu pangan merupakan disiplin ilmu terkait dengan teknik, biologi, dan fisik yang digunakan untuk mempelajari karakteristik pangan, penyebab kerusakan pangan, prinsip pengolahan pangan, dan usaha peningkatan pangan untuk konsumsi masyarakat. Teknologi pangan merupakan aplikasi ilmu pangan untuk menyeleksi, mengawetkan, mengolah, mengemas, dan mendistribusikan pangan yang bergizi tinggi sesuai dengan rambu-rambu keamanan pangan. Apabila dilihat dari definisinya, teknologi pangan terkait dengan ilmu pangan sebagai basisnya sehingga sering kedua definisi tersebut saling dipertukarkan. Alasannya seseorang yang menguasai ilmu pangan dan teknologi pangan harus memahami karakteristik komponen bahan pangan sekaligus mampu menghasilkan pangan yang bergizi dan aman untuk dikonsumsi.

A total of 6 fungi isolates of growing at pH 9 and 2 isolates on pH 10 with amylolytic indexes 0f 0.07-1.42 have been isolated from cassava starch liquid waste. Two isolates having the highest amylolytic index were identified as Aspergillus sydowii K10 (1.42) and Aspergillus versicolor L30 (1.4). Both A. sydowii K10 and A. versicolor L30 were described as alcalotolerant for being able to grow with range pH 5-10. The optimal ï¡-amylases production of A. sydowii K10 and A. versicolor L30 was obtained after 4 and 3 days of incubation at 300C. The optimum of ï¡-amylase activity from A. sydowii K10 was at 400C and 700C, and pH 6; while those from A. versicolor L30 was at 500C and pH 6 respectively. Both A. sydowii K10 and A. versicolor L30 could produce glucoamylase. The optimum of glucoamylase activity from A. sydowii K10 was at 400C and pH 5, while those from A. versicolor L30 was at 500C and pH 5 respectively.

Strategi Konservasi di Pulau Sulawesi dengan Menggunakan Tarsius sebagai Flagship Spesies Shekelle, Myron; Leksono, Suroso Mukti

We present a strategy to preserve the biodiversity of Sulawesi and nearby islands chains. Sulawesi is the primary landmass in the biogeographic zone known as Wallacea, and is listed as one of the worldâ€™s top 25 hotspots at threat for major loss of biodiversity. Sulawesi is hypothesized to be subdivided into regions of endemism. We argue that the best strategy for preserving the totality of Sulawesi biodiversity, given that the vast bulk of that biodiversity remains virtually unstudied or even unknown, is to use biogeographic data to make a comprehensive map of regions of endemism in Sulawesi and to protect primary habitat in each region. We present a hypothesis that we call the â€œhybrid biogeographic hypothesisâ€ that synthesizes two previous biogeografic hypotheses, one from empirical biological data and one from geologic data. We present a map of tarsier acoustic group distributions that offers heuristic evidence that the former hypothesis is more comprehensive than either of the latter two. We note that some of these regions have multiple conservation areas, while several others have none at all and can be thought of as â€œhotspots within the hotspotâ€. Evidence indicates that an endemic taxon of tarsier inhabits nearly every known endemic region of Sulawesi and surrounding island chains, although most of these taxa are undescribed. We propose to use tarsiers as flagship species to justify new conservation areas that will preserve primary habitat in those regions that currently lack them. Tarsiers are superior to other potential flagship species because they have the requisite charisma and are distributed throughout Sulawesi in a broad variety of habitats, but they do not eat agricultural products or have other characteristics that might engender local resentment to their conservation. This plan requires naming several new taxa of tarsiers, each of which requires reference material. Existing museum populations are inadequate for these needs and new museum specimens are required. We argue that the most beneficial way for this program to proceed is to trap wild tarsiers and house them in captivity until they expire naturally, at which time they will enter the collections of the Museum Zoologicum Bogoriense. While in captivity these tarsiers will provide enormous opportunities for research, training, education, and conservation. We will encounter local resistance to conserving tarsier populations because of false perceptions among inhabitants that tarsiers eat agricultural products, and this false belief must be corrected through community education. The critical condition of habitat destruction in Sulawesi warrants immediate action.

A new strain characterized as Bacillus sp. PSA10 was found to produce poly-Î²-hydroxybutyrate (PHB) at concentration of 52.28% (g PHB/g dry cell weight) in shaken flask culture, using sago starch as a carbon source. This research is aimed to determine the optimum culture condition of PHB production Bacillus sp. PSA10 at laboratory scale. Optimization of PHB production was conducted in this research, in terms of inoculum concentration, concentration of the major components in minimal medium, environmental condition and incubation time. The result showed that optimum conditions for the production of PHB by Bacillus sp. PSA10 were achieved at minimal medium (Ramsay medium) with 5% (v/v) inoculum concentration, 2% (w/v) sago starch, 1.0 g/l (NH4)2SO4, 6.7 g/l Na2HPO4.7H2O, and 0 g/l KCl. The optimum environmental conditions were achieved with initial pH 7, temperature 37oC, agitation speed at 150 rotary per minute (rpm) and the best of incubation time was 48 hour. Under this optimum condition, the maximum PHB production by Bacillus sp. PSA10 increased from 52.28% to 71.35% (g PHB/g dry cell weight) at 48 hour cultivation. Therefore, Bacillus sp. PSA10 is potential to apply for PHB production from sago starch at industrial scale.

National Park is a nature conservation area has a wildÂ ecosystem and managed by zone system. Baluran National Park (BNP) is one of conservation area in Indonesia covered 25,000 hectare consists of 420 hectare of Bekolâ€™s savanna and 150 hectare of Bamaâ€™s savanna. FromÂ 4.345 grass-feeding mammalÂ in BNP, it has estimated that their total weight aboutÂ 777,000 kgÂ andÂ the total feeding needÂ about 77,700 kgÂ per day. On the other hand, the biomass of the grasslands only 86.125 kg/ha/day, and both Savannas could only produce biomass about 40,478.75 kgÂ per day which wasÂ not enough to support the daily animal feeding. Decreasing of the biomass in BNP was assumed as a result of habitat destruction by animal step printings.Â The purpose ofÂ this study is to know the effect of animal step printing to the biomass production.Â Samples was taking from April to December 1999 using quadrates method which was applied following the animal step printing and the control (non-stepped area). The plant samples were kept in plastic pocket and then identifiedÂ in the laboratory. The totalÂ number of quadrates could be detected in this study were 150.Â From this study it was concluded thatÂ Grassland which was stepped by banteng, water buffalo and deerÂ decreased the number of plant speciesÂ until 38.88%, 27.27% and 18.18% respectively.Â Â

This study wanted to elucidate the role of tourists activities to the beach such as Krakal Beach, Yogyakarta. The method used in this research was direct interview to the visitors using accidental sampling with the help of prepared questionnaire. This study showed that 86% visitors were in their school age. Person in this age like such a challenge like what they met during beach visit. Those make the visitation frequency quite high by repeating their visit (53,5%). Shells and shells handicrafts has been proven to be the reason why visitors come back to visit the beach (79%). Apparently, visitors agree that the snailsâ€™ forms and colors are attactive (70,9%), beautiful and unique (75,6%), but only 14% said that it shouldnâ€™t be disturb by human activities. Their attractiveness to the snails did not make them to collect intentionally, enough for them to see and let them go (66,2%). They did not agree that visitors collected them (51,2%), but they agree harvesters make a souvenirs and get an income from this activity (67,4%). In short, they were much environment friendly (57%) rather than economic friendly (43%). Â
