Slow sand filter is one of the processing methods that is chosen because of easy-to-obtain tools and materials, easy to operate, and its effectiveness of removing contaminants in good water.To improve the reliability of slow sand filter removal, preliminary processing can be carried out, one of which is pre-sedimentation. The purpose of this study was to compare the reliability of slow sand filters with pre-sedimentation processes and slow sand filters without pre-sedimentation in removing iron, manganese, turbidity and faecal coliform. Two filters are created from a 150 liter drum with the same specifications. Media filters are planned with the same specifications, but when sieve analysis is obtained the results are: for reference filter, sand layer 1 ES value = 0.2 mm and UC = 3 & in sand layer 2 ES values = 0.45 and UC = 2.2 . While filter I sand layer 1 ES value = 0.15 mm, UC = 2.33 and sand coating 2 ES values = 0.4 mm and UC = 1.88. Both filters are operated intermittently on a pilot scale. The raw water source used as the object of study is the Lake Mahoni, University of Indonesia because of the level of pollution that is above the drinking water quality standard. Removal efficiency of reference filter with treatment of pre-sedimentation for iron removal was 95%-97.94%, manganese 50-80%, turbidity 92.15-97.78%, and faecal coliform 90-99.57%. The efficiency of filter I without prasedimentation for iron parameters cannot be excluded, manganese is 50-93.33%, turbidity 50.28 - 94.26%, and fecal coliform 82.61-99.86%."

"Berdirinya sebuah kampus mempengaruhi harga tanah disekitarnya atau ada faktor faktor lain yang mempengaruhi harga tanah. Harga tanah setiap tahun semakin meningkat dan jumlah luas tanah tidak bertambah. Harga tanah yang berada di dekat jalan utama, stasiun dan pusat perdagangan memiliki harga tinggi. Kampus menjadi pusat kegiatan perkuliahan. Kampus memberikan pengaruh terhadap pusat kota. Harga tanah tertinggi berada pada jarak sangat dekat dari kampus dan pusat kota. Penggunaan tanah dengan harga tertinggi adalah penggunaan tanah perdagangan dan jasa. Jarak yang dekat dari kampus memungkinkan tanah dapat diakses dengan waktu yang singkat, sehingga tidak memerlukan biaya tambah dan biaya perjalanan dapat berkurang. Jarak semakin jauh memerlukan waktu dan biaya yang semakin bertambah untuk mengakses suatu tanah. Tanah yang berada pada jarak yang sangat jauh dari kampus dan pusat pusat lainnya memiliki harga tanah yang rendah.

The establishment of a campus affects the price of land around it or there are other factors that affect the price of the land. Result shows that land price increases every year, yet the land area does not. For example, the land price near the main road , train station, and market center have indeed high price. Campus, therefore, becomes the center of student activities, thus it gives affects to center city area. Result shows that the highest land price is located very near from campus and center city. The land use with the highest price is in forms of land use for trades and service. A short distance from the campus allow the land can be accessed with a short time, so it does not require the added cost and travel expenses can be reduced. Distance farther requires time and increasing costs for accessing a land. lands are at a great distance from the campus and other centers have low land prices."

"Kota Depok saat ini terdapat banyak institusi pendidikan yang terus berkembang. Keberadaan institusi pendidikan tinggi ini tentunya akan membawa pengaruh pada kawasan sekitarnya, antara lain perubahan fungsi bangunan, perubahan sosial ekonomi dan adanya peningkatan volume lalu lintas akibat adanya pertambahan jumlah mahasiswa yang tinggal di sekitar institusi pendidikan tersebut. Disini, kehadiran perguruan tinggi menyebabkan terjadinya permintaan dari mahasiswa akan tempat tinggal, sehingga kawasan itu menjadi hunian yang memerlukan berbagai fasilitas pendidikan. Dan hal ini menyebabkan perkembangan pada kawasan tersebut. Selain berperan penting terhadap perkembangan kawasan sekitar kampus, sebagai mahasiswa diharapkan juga dapat mengembangkan karakter dirinya guna menjalankan peran dan fungsinya di masyarakat. Namun hal ini tidaklah terlihat pada kawasan sekitar kampus Universitas Indonesia, Depok. Mahasiswa menjadikan kawasan hanya sebagai tempat tinggal. Peran dan fungsinya bagi masyarakat lokal masih belum terlihat. Hal ini dikarenakan mahasiswa belum dapat mengembangkan karakter dirinya atau bereksplorasi pada kawasan tersebut. Tulisan ini berusaha untuk melihat dan menata kawasan sekitar kampus Universitas Indonesia dengan menggunakan pendekatan student city. Diharapkan agar kawasan dapat menjadi wadah mahasiswa dalam mengeksplorasikan dirinya, sehingga selain berguna bagi pengembangan dirinya, mahasiswa juga dapat menjalankan peran dan fungsinya di dalam bermasyarakat.

There are many educational institutons in Depok City that continue to grow. The existence of those educational institutions takes effects for the neighborhood, i.e. the changes of building fuction, social economics, and the increasing of traffic volume as the impact of the increasing number of student living around the educational institutions. The existence of higher education institutions causes the demand for residence that should be equiped with educational facilities. Those make the development of the area around the campus.

In addition to the important role for the development of the area around the campus, students are expected to be able to develop their character in order to carry out their role and function in society. But this is not seen in the area around the University of Indonesia, Depok. Students make the area only as a residence. Their roles and functions within local community are still not visible. That is because the students have not been able to develop their character and explore the area.

This article tries to view and organize the area around the campus of University of Indonesia using student city approach. It is expected that the area can a place for students in exploring themselves, so in addition to useful for their development, students can also perform their role and functions within the community."

"Water is one of the very necessary essence in human life aspects, which education is being one of them. As one of the best universities in Indonesia, University of Indonesia provides and find some ways to save clean water by minimizing the use amount of it, especially to reduce groundwater uses, as its noted in the UI GreenMetric purpose of clean water category. However, one of the faculties in UI, which is the Faculty of Nursing (FIK UI), have used a massive amount of groundwater in 2018 and 2019, with the amount number being 2.115.240 litres and 2.010.960 litres respectivel. FIK UI must find an alternative of water source other than groundwater, such as surface water. The purpose of this research is to design a water treatment system using the Agathis UI Lake water as the source to serve FIK UI need of clean water until 2042. The operation unit being the main focus of this designing process is the filtration using slow sand filter with silica sand and granular activated carbon as the filter medias, which both known effective to reduce iron, manganese, and fecal coliform concentration in raw water as the three parameters are important criterias in the Indonesias Health Minister Rule number 492 year 2010 about The Criterias of Drinking Water Quality. The amount of clean water need of FIK UI projected is 2,82 L/s. This design based on literatures and legal standards, especially in deciding the removal efficiency of the three parameters being said before of the slow sand filter.

"Termites are a group of invertebrates abundant in forested habitats. In this study, we conduct an inventory and spatialanalysis of the termite fauna of the UI campus. The survey records the presence of six termite species (Coptotermescurvignathus, Schedorhinotermes javanicus, Macrotermes gilvus, Microtermes insperatus, Odontotermes grandiceps,and Odontotermes javanicus), most of which had been reported by previous studies. The spatial analysis of termite nestdistribution suggests a random scattering of termite nests in the UI campus."
