<p>The Sea Beach Cahaya is one of the rising beach attractions in Kendal Regency, Central Java. In general, the tourism object of The Sea Pantai Cahaya still does not use many computer systems in their daily lives. As with tourism ticket purchases and also entrance tickets, vehicles that still use ticket paper as proof of payment, it is often disrupted if it is still fussing with the queue conditions and questions by visitors. On the other hand, report data collection is still considered slow.</p><p>One way to overcome the above problems is to make a ticket payment system that is computerized using the SAW (Simple Additive Weighting) method, replace paper tickets with a card model and also use the network to shorten report generation.</p>

Face Threats

The unique primates of south-eastern Madagascar face threats from growing human populations. The country's extant primates already represent only a subset of the taxonomic and ecological diversity existing a few thousand years ago. To prevent further losses remaining taxa must be subjected to effective monitoring programmes that directly inform conservation efforts. We offer a necessary first step: revision of geographic ranges and quantification of habitat area and population size for diurnal and cathemeral (active during both day and night) lemurs. Recent satellite images are used to develop a forest cover geographical information system, and censuses are used to establish range boundaries and develop estimates of population density and size. These assessments are used to identify regions and taxa at risk, and will be a useful baseline for future monitoring of habitat and populations. Precise estimates are impossible for patchily-distributed taxa (especially Hapalemur aureus, H. simus and Varecia variegata variegata); these taxa require more sophisticated modelling.
