CiliwungRiver water quality and its vicinity have been continuously degraded with the increasing population. The objective of this research is to understand the association between river and groundwater, and the water quality profile. Field measurements ware taken from 65 stations from Bogor to Jakarta. Water level, temperature, pH, and TDS were measured to build the water flow map and hydrochemical profile. Small-scale geoelectrical survey was conducted at five locations to capture the aquifer's geometry. We identified three types of stream relationships between river and groundwater: effluent from Bogor to Katulampa (Segment 1), perched at the University of Indonesia (UI) area (Segment 2), and influent from UI to Muara (Segment 3), with low gradient from \0.1 to 0.3. The temperature profile of river and groundwater shows similar pattern as well as TDS profile. All similarities support close connection of river and groundwater. The increasing TDS towards downstream shows increasing enrichment and contamination. The erratic pattern of pH indicates chemical instability due to high contamination. This study highlights the benefit of understanding the hydrodynamic relationship between river water and groundwater. Such interaction triggers water quality exchange between both water bodies. Therefore, a similar study should also be done on other riverbanks in Indonesia to protect water quality.

Introduction. The quality of journals in Indonesia is much criticized; however, the number of Indonesian journals that meet the criteria of Directory of Open Access Journal (DOAJ) is quite a lot. This study describes some facts of Indonesia’s publications based on DOAJ and World Bank data.Data Collection Method. Some filtering processes in DOAJ database were done based on sum of journals, scientific fields distribution, and Article Processing Charge (APC). Open data regarding research funds among countries in World Bank database were analyzed.Data Analysis. This study used quantitative-descriptive design with frequency analysis technique. Data visualization was done with R Statistical Computing and Google Sheets.Results and Discussions. In March 2017, there were 500 Indonesian journals (5th rank worldwide); 420 of them were in Indonesian covering more than 51,000 articles (7th rank). The top three fields were: education, Islam religion, as well as business and commerce. As much as 70% of the journals were free of APC. Science must prioritize inclusiveness and equality inline with the principles of originality and honesty.Conclusions. This study concludes that open access journals in Indonesia improves the accessibility, quality, and relevance of Indonesian research, which can be reused by communities, industries, and the government.

AbstrakSejak dipopulerkan oleh F. Stuart Chapin Jr pada tahun 1957, konsep tata guna lahan perkotaan sudah menyinggung unsur-unsur terkait geologi. Meningkatnya jumlah penduduk dunia yang tinggal di perkotaan pun menjadikan geologi makin dibutuhkan untuk memastikan kota yang berkelanjutan. Penelitian ini dilakukan untuk mengetahui bagaimana geologi telah dimanfaatkan untuk tata guna lahan perkotaan. Artikel ilmiah yang relevan dalam jurnal dan prosiding terindeks Scopus (1950Scopus ( -2019 dianalisis dengan metode tinjauan pustaka sistematis (SLR). Parameter yang dianalisis meliputi aspek jumlah terbitan, pilihan jurnal, ketokohan penulis, asal negara dan institusi penulis, sub-topik pembahasan, kata kunci dan jumlah kutipan. Hasil analisa selanjutnya dipetakan dengan aplikasi VOSviewer. Total 216 artikel ilmiah yang relevan telah diidentifikasi, dan hasilnya telah mampu menjawab negara dan institusi mana saja di dunia yang intens meneliti aplikasi geologi untuk tata guna lahan perkotaan. Publikasi terkait juga cenderung mengalami peningkatan signifikan pada kurun waktu tahun 2002 hingga 2013. Topik populer penelitian adalah tentang mengukur potensi bahaya dan kerentanan suatu wilayah dari potensi tanah longsor, amblesan (di zona karst), kekeringan, banjir dan gempabumi di Kawasan Perkotaan berbasis metode GIS dan AHP. Kata-kata kunci: Geologi perkotaan, Tinjauan pustaka sistematis, Tata guna lahan, PENDAHULUAN Teori yang pertama kali menjelaskan pola tata guna lahan di perkotaan diungkapkan oleh Ernest Burgess di tahun 1923. Burgess mengungkapkan bahwa sebuah kota berkembang dari satu titik pusat menuju serangkaian zona konsentris [1,2]. Teori ini disempurnakan oleh Homer Hoyt di tahun 1933 serta Harris dan Ullman di tahun 1945 bahwa perkembangan kota tidak semestinya konsentris, tetapi mengikuti sektor-sektor tertentu sehingga terbentuk beberapa titik pusat perkotaan [2]. Meningkatnya fenomena urbanisasi terutama
