Sanitasi dasar merupakan sarana dan prasarana minimal yang harus dimiliki oleh setiap hunian. Fasilitas-fasilitas yang termasuk dalam sanitasi dasar meliputi penyediaan air bersih, pembuangan air limbah, saluran drainase, dan pengelolaan sampah. Buruknya kualitas sanitasi dasar dapat menyebabkan kekumuhan di suatu permukiman. Sayangnya, fenomena tersebut terlihat pada beberapa permukiman pesisir di Kepulauan Riau yang notabene memiliki potensi sebagai desitinasi wisata budaya. Oleh karena itu, penelitian kualitatif ini bertujuan untuk menganalisis ketersediaan dan kondisi sanitasi dasar di Kampung Datuk, Pulau Penyengat, Kota Tanjung Pinang, Kepulauan Riau. Observasi lapangan dilakukan untuk memperoleh data primer. Hasil penelitian mengungkapkan bahwa warga kampung ini masih menyalurkan air limbah dan drainase langsung ke laut. Meski dianggap belum memenuhi standar sanitasi dasar yang baik secara menyeluruh, permukiman pesisir Kampung Datuk di Pulau Penyengat telah cukup sadar untuk mengelola sampah dengan baik dan juga telah tersedia sarana air bersih yang cukup untuk memenuhi kebutuhan warga sehari-hari. Oleh karena itu, penulis memberikan beberapa rekomendasi dalam penelitian ini, khususnya yang berkaitan dengan sistem pembuangan air limbah dan saluran drainase di permukiman tersebut.

<p>Engku Puteri Square is an open field which is usually called “Alun-Alun”, located next to the mayor's office of Batam which was originally planned as a public open space and venue for the ceremony ground of the Batam City civil servants. The concept of structuring the city square in several cities in Indonesia has been started since a long time ago, the city square has a potential role to be one of the city identities. This is important because we are now experiencing an identity crisis, especially in the field of architecture or urban planning.Engku Puteri square became a different public space when in 2003 the Municipality of Batam decided to construct the fence around the square area, especially when the Alun-Alun was decided to be the location for the implementation of the National MTQ when the Riau Islands Province hosted the event in 2014. A few months before National Level MTQ being held, there were a large renovation done, such as the addition of towers and gates permanently. The pulpit and Astaka used as the main arena of MTQ activities are also built magnificently. The Engku Puteri, which used to have an open concept now becomes more intimate and different from the initial concept, all might be due to the lack of awareness of the public and policy makers about the concept of public open space. The purpose of this paper is to find a concept of the city square that will be compared with the existing conditions as a consideration to restore the actual function of the Engku Puteri City Square.</p>
