This paper is a continuous study that outlines Self Compacting Concrete (SCC) behavior on high strength concrete with nickel slag as fine aggregate. The percentage of nickel slag substitution as fine aggregate varies from 0% to 100% with an increase of 25%. This laboratory study aims to obtain the effect of seawater curing on the concrete compressive strength. The specimens immersed in seawater for 220 days will provide a SCC behavior assessment towards seawater immersion. The results obtained show that concrete with 25% nickel slag gives the most maximum effect. Compared to concrete without slag, SCC with 25% nickel slag has a higher compressive strength of 17%. Besides, the slump test also showed good condition. All specimens using nickel slag in seawater immersion show greater strength when compared to non-slag concrete. This means that concrete is very suitable at a curing age of 220 days when substituted with nickel slag. The mixture using nickel slag of 100% (SCC100 specimen) illustrates a reasonably stable strength from 28 days of immersion.

Resilient city memiliki beberapa prinsip di antaranya prinsip ketahanan bencana, ketahanan pangan, ketahanan infrastruktur, ketahanan sosial, ketahanan sumber daya, serta integrasi alam. Melihat masalah yang ada di Kota Kendari, salah satu konsep yang paling efektif untuk diterapkan adalah konsep ketahanan infrastruktur. Sebagai mesin pertumbuhan, infrastruktur kota mempunyai risiko untuk terkena dampak bencana. Penelitian ini bertujuan untuk mengetahui kondisi eksisting infrastruktur yang ada di Kota Kendari serta bagaimana menerapkan prinsip-prinsip ketahanan kota (Resilient City) pada Infrastruktur di Kota Kendari khususnya di kawasan BWK V sebagai lokasi yang cukup rawan bencana banjir. Penelitian ini menggunakan metode deskriptif kualitatif dimana Cognitive Mapping digunakan sebagai teknik analisisnya. Hasil penelitian menunjukan bahwa kondisi infrastruktur di lokasi penelitian dari segi fisik belum memadai. Ketahanan infrastruktur yang berbasis pada resilient city dapat diterapkan mulai dari tahap perencanaan sampai pemeliharaan. Penelitian ini diharapkan dapat digunakan oleh pemerintah sebagai acuan dalam mengembangkan kota berketahanan terhadap bencana.

The New Campus of Halu Oleo University (UHO) is one of the state universities included in the term of the largest university in Eastern Indonesia with an area of more than 252 Ha. Located in the central government development area, UHO’s New Campus has become an attractive campus, shown by the increasing number of prospective students from year to year. This increasing number causes the university to provide educating facilities as the main need. The existing buildings and future development projects have not considered the concept of good spatial planning. This threatens the availability of land, especially the availability of open space and also affects the arrangement of related elements such as vehicle circulation, building utilities, drainage systems and mechanical-electrical. The purpose of this research is to provide a recommendation about the design of the UHO campus spatial layout which optimizes 60% open space availability proportionally with a more directed structuring concept. This research employed a qualitative method and data was collected through questionnaires and observations. The results indicate that the current space utilization is not well arranged, therefore affects other elements. Through the concept of cluster eco, campus area will be more organized.
