Abstract

The development of wild caves into show caves is required an installation of electric lights along the cave passages for illumination and decoration purposes for tourist attraction. The presence of artificial lights can stimulate the growth of photosynthetic organisms such as lampenflora and alter the typical cave ecosystem. The study was aimed to detect the effect of lampenflora on cave-dwelling arthropods community. Four caves were sampled during the study, 2 caves are show caves with the existence of lampenflora and 2 others are wild caves without lampenflora. Arthropods sampling were conducted by hand collecting, pitfall trap, bait trap and berlese extractor. Lampenflora comprises of algae (Phycophyta), moss (Bryophyta) and fern (Pteridophyta) grow mostly around white light lamps. Richness, diversity, and evenness indices of Arthropods are higher in caves with the existence of lampenflora compared to caves without lampeflora. This study clearly shows that the presence of lampenflora can increase Arthropods diversity and suppress dominancy of common Arthropods species in caves, also increasing the relative abundance of predators. This condition will shift the ecosystem equilibrium and lead to cave ecosystem destruction. The results of this study should be a scientific consideration for show cave development and management. Lampenfloras have to be removed from all caves and preventive efforts should be taken to minimize their growth.

Abstract

Orbit Perdana store is a store that is engaged in the sale of household electronic goods. The process at this store is still done semi-manually, for order entry, ordering goods and stock recording is done manually. However, for the manufacture of goods price list is computerized. It can bring harm to the company, for example, for recording miscalculation could happen that could bring harm to the company, then on receipt of the order, which can not be faulted human memory is limited so that it can make a person forget, it can be disappointing customer so that the company valued less by the customer. Section while ordering goods, miscommunication can occur between the owner who ordered goods to the supplier, which could also bring losses for companies such as excessive stockpile goods.Based on the problems being faced, then the web-based application is administration system is designed to provide the results of the performance of the recording company orders, booking orders, and company reports.Based on the test results, this application can record company data, supplier, customer, stock of goods, accounts payable and receivable, sales returns and purchase, and reports.  Applications can also provide flexibility to the owner to be able to perform charging master data without having to go through the application directly
