<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>

Pengumpulan data kuantitatif melalui pengisian kuesioner, pengumpulan data kualitatif melalui FGD dan wawancara. Analisis data penelitian dilakukan dengan menggunakan perangkat Evaluasi SIK Provinsi yang merupakan modifikasi dari Assessment Tool HMN Versi 4.00. Modifikasi Assessment Tool HMN Versi 4.00 dilakukan dengan cara menghapus item pertanyaan yang tidak relevan dengan SIK di provinsi dan menambahkan item pertanyaan berdasarkan PP no 46/2016 tentang SIK. Hasil evaluasi terhadap tujuh komponen SIK, empat diantaranya dinilai “ada tapi tidak adekuat” yaitu komponen pengelolaan (54,7%), sumber daya (54,2%), sumber data (58%) dan manajemen data (41,3%). Sementara tiga komponen lainnya dinilai “adekuat”, yaitu komponen indikator (74,3%), produk informasi (71,3%) dan diseminasi dan penggunaan informasi (74,5%).Disimpulkan bahwa secara umum SIK Provinsi Jawa Tengah berada dalam kategori “adekuat”. Untuk meningkatkan pengelolaan SIK di Provinsi Jawa Tengah, direkomendasikan untuk membuat suatu standar tata kelola SIK sebagai acuan pengelolaan SIK di Provinsi Jawa Tengah. Evaluation of Health Information System (HIS) aimed at ascertaining the efficient implementation of HIS that could result relevant and high-quality information to be used as a basis of making a decision by a decision maker. The result of HIS assessment was needed to improve the HIS performance. HIS of Central Java Province was a sub-system of National Health Information System (NHIS) in which the development of HIS there would strengthen the NHIS. The aim of this study was to evaluate HIS in Central Java Province in order to strengthen NHIS. This was a descriptive-evaluative study using quantitative-qualitative approach. Research subjects were 35 HIS officers at District Health Office (DHO) and six HIS officers at Central Java Province Health Office. Quantitative data were collected by filling a questionnaire whereas qualitative data were collected by conducting FGD and indepth interview. Data analysis was performed using a software of Province HIS evaluation that was modified from Assessment Tool HMN version 4.00. Modification of Assessment Tool HMN version 4.00 was performed by deleting questions that were irrelevant with HIS at province and adding questions based on government regulation number 46/2016 about HIS. The results of evaluation of seven components of HIS, four of these seven components indicated “available but inadequate”, namely components of management (54.7%), resource (54.2%), data source (58%), and data management (41.3%). In contrast, three of these seven components were “adequate”, namely components of indicator (74.3%), information product (71.3%), and dissemination and use of information (74.5%). To sum up, generally HIS of Central Java Province was categorised as “adequate”. To improve HIS management in Central Java Province, a standard of HIS management needs to be made as a reference to manage HIS in Central Java Province.

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.
