Comparing the Data Quality of Global Positioning System Devices and Mobile Phones for Assessing Relationships Between Place, Mobility, and Health: Field Study

Wilayah perkotaan di Indonesia memiliki karakteristik yang sama dengan wilayah perkotaan di negara-negara berkembang. Beberapa karakteristik tersebut seperti: (1) penurunan fungsi alam dengan berkurangnya ruang hijau atau vegetasi, (2) penumpukan bangunan beratap pada wilayah yang dekat dengan akses transportasi, industri dan pasar, (3) lokasi pemukiman pada zona yang berbahaya karena dekat dengan terminal, sepanjang aliran sungai, sepanjang jalur rel kereta api, dan tempat pembuangan sampah akhir. Keterkaitan antara nilai indeks kemiskinan dengan morfologi fisik dan vegetasi suatu wilayah dapat diketahui dengan pemanfaatan teknologi remote sensing (RS). Keakuratan analisis pemukiman miskin dengan teknologi RS bergantung pada kualitas citra satelit Very High Resolution (VHR) dan kelengkapan dataset Sistem Informasi Geografis (SIG). Teknologi Geospasial yang terintegrasi seperti RS, SIG, dan Global Positioning System (GPS) dapat berkontribusi secara interaktif dalam penilaian, pemahaman dan pemetaan untuk memecahkan masalah pemukiman penduduk yang kompleks di Indonesia. Urban areas in Indonesia have the same characteristics with urban areas in developing countries. Some characteristics such as: (1) decreased of the function of nature with the reduced the number of natural green space or vegetation, (2) accumulation of roofed buildings in the area close to transportation access, industry and market, (3) the location of housing in the dangerous zone as close to the terminal, along the river side, along the railway lines, and the final waste disposal sites. The linkage between poverty index values with the physical morphology and vegetation of an area can be identified by the use of technology and remote sensing (RS). The accuracy of the analysis of poor housing with RS technology relies on the image quality of Very High Resolution (VHR) satellite and the completeness of the dataset Geographic Information Systems (GIS). Geo-spatial technologies are integrated as RS, GIS, and Global Positioning System (GPS) can contribute interactively in the assessment, understanding and mapping to solve the complex problem of residential in Indonesia.

Dewasa ini, masih banyak didapati kecurangan presensi kehadiran saat bekerja seperti melakukan titip absen kepada pegawai lain atau hanya absen saat jam masuk dan jam pulang, namun pegawai tersebut tidak sedang berada di kantor selama jam kerja. Hal ini dapat menyebabkan produktifitas menurun yang berakibat pada kualitas pegawai. Permasalahan ini dapat diselesaikan dengan memanfaatkan penerapan teknologi informasi dan komonukasi seperti Global Positioning System (GPS) yang dapat mendata informasi spasial seseorang dalam area lingkup. Melalui aplikasi android pada setiap perangkat yang dimiliki pegawai, dapat memudahkan serta transparansi dari kegiatan presensi. Sistem didalamnya akan membatasi cakupan area lingkup dengan area luar lingkup yang diambil dari titik koordinat latitude dan longtitu ditempat kerja. Lingkupan area ditentukan dari radius pada masing-masing lokasi. Nilai koordinat dijadikan dasar dalam kehadiran serta waktu kerja yang ditentukan dan dicek secara berkala atau interval waktu. Adapun tingkat keberhasilan system presensi berbasis geolokasi yang telah diperoleha dalah rata-rata 92% dengan rincian 98% di area Teknik Informatika, 100% di area rektorat, dan 80 % di area 454. Today, there are still many cases of attendance fraud while working, such as entrusting absences to other employees or only absent during entry and return hours, but these employees are not in the office during working hours. This can lead to decreased productivity which results in the quality of employees. This problem can be solved by utilizing the application of information and communication technology such as the Global Positioning System (GPS) which can record a person's spatial information within the scope area. Through the Android application on every device owned by employees, it can facilitate and transparency of attendance activities. The system inside will limit the coverage area of the scope to the area outside the scope which is taken from the latitude and longitude coordinate points of the work place. The area coverage is determined from the radius at each location. Coordinate values are used as the basis for attendance and work time which is determined and checked periodically or at time intervals. The success rate of the geolocation-based presence system that has been obtained is an average of 92% with details of 98% in the Information Engineering area, 100% in the rectorate area, and 80% in the 454 area.

Kondisi perairan suatu wilayah memiliki tingkat kesuburan yang berbeda – beda salah satunya pada Perairan Jawa khususnya bagian utara. Perairan Utara Jawa memiliki kondisi arus dan gelombang yang cukup stabil dimana hal ini berpengaruh terhadap kandungan yang terdapat di dalamnya. Perairan Kendal merupakan salah satu perairan yang terletak di Utara Jawa yang dimanfaatkan dalam kegiatan perikanan. Kendal merupakan Kabupaten yang memiliki hasil tangkapan ikan yang cukup besar yang dimanfaatkan masyarakat untuk kehidupan sehari- hari. Kabupaten Kendal juga terkenal dengan kegiatan industri seperti industri Kayu Lapis. Kegiatan industri berdampak terhadap kondisi perairan di Kendal karena buangan limbah cair maupun padat yang dapat mempengaruhi tingkat kesuburan. Tingkat sesuburan perairan dapat dilihat salah satunya dari kandungan klorofil-a yang terdapat di dalamnya. Kandungan klorofil-a pada perairan dapat dilihat melalui banyaknya fitoplankton karena fitoplankton merupakan penghasil klorofil-a tertinggi di perairan. Tujuan dari penelitian ini adalah untuk mengetahui kualitas Perairan Kendal dilihat dari kandungan klorofil-a dan fitoplankton. Metode yang digunakan dalam penelitian ini adalah metode deskriptif, metode deskripstif dimaksudkan untuk mendapatkan gambaran tentang kualitas perairan melalui sebaran kandungan spasial klorofil-a pada Perairan Kendal. Teknik penentuan lokasi sampling dan pengambilan sampel menggunakan metode purpose sampling. Pengambilan data lapangan dilakukan sebanyak 10 titik. Titik lokasi ditandai menggunakan Global Positioning System. Hasil yang didapatkan dari penelitian menunjukkan hasil persebaran konsentrasi klorofil-a pada masing – masing stasiun berbeda dan hasil kelimpahan fitoplankton yang di dapatkan juga berbeda tetapi sesuai dengan konsentrasi klorofil-a pada masing – masing stasiun. Perbedaan disebabkan karena adanya faktor perbedaan lokasi sampling. Konsentrasi klorofil yang tertinggi terdapat pada stasiun 6 sebesar 1,7025 mg/m³ dan kelimpahan fitoplankton tertinggi juga pada stasiun 6 sebanyak 43.373 sel/L.The condition of the waters of an area has different fertility levels - one of which is in the Java waters especially in the north. The waters of North Java have relatively stable currents and waves which affect the content contained therein. Kendal waters is one of the waters located in North Java that is used in fisheries activities. Kendal is a regency that has a large enough fish catch that is utilized by the community for daily life. Kendal Regency is also famous for industrial activities such as the Plywood Industry. Industrial activities have an impact on water conditions in Kendal because of liquid and solid waste discharges that can affect fertility. Water fertility can be seen one of them from the content of chlorophyll-a contained in it. Chlorophyll-a content in water can be seen through the number of phytoplankton because phytoplankton is the highest chlorophyll-a producer in water. The purpose of this study was to determine the quality of Kendal Waters in terms of chlorophyll-a and phytoplankton content. The method used in this research is descriptive method, descriptive method is intended to get a picture of the quality of waters through the distribution of spatial content of chlorophyll-a in Kendal waters. The technique of determining the location of sampling and sampling uses the purpose sampling method. Field data collection was carried out by 10 points. Location points are marked using the Global Positioning System. The results obtained from the study showed that the distribution of chlorophyll-a concentrations at each station was different and the results of the abundance of phytoplankton obtained were also different but in accordance with the concentration of chlorophyll-a at each station. The difference is due to the sampling location difference factor. The highest chlorophyll concentration was found at station 6 at 1.7025 mg/m³ and the highest phytoplankton abundance was also at station 6 as many as 43,373 cells/L.

Technological Improvements

The use of global positioning system (GPS) technology underpins many different methods of tracking. GPS tracking involves the use of a beacon that sends the location of a device to satellites to determine the precise location of the beacon. In recent years, technological improvements have meant that GPS tracking units have become exponentially smaller in size. Whereas early portable beacons such as the Magellan (launched in 1989) were 22 cm in length and around 700 grams in weight, if not larger than television screens, they can now fit into the back of watches and mobile phones (Shoval and Isaacson, 2010). This chapter will explore the development of GPS technology and its application to tourism research, when utilised with portable GPS loggers.

The Right

The crucial question that this chapter examines is whether an employer may track employees during work hours using the Global Positioning System (GPS) without violating employees’ right to privacy. This chapter argues that GPS installation in employer-owned mobile phones and computers can coexist harmoniously with employees’ right to privacy when the GPS tracking does not seek to keep track of employee whereabouts but, instead, to optimize a travel route and enhance employee safety by providing the possibility of immediate intervention if necessary, such as when a specified location is needed. If a GPS has been installed in order to assist employees in reaching a destination most efficiently, then this system must be placed solely and exclusively for this purpose, and the employee must retain the right to deactivate it at will.
