Ternate City as an old city and has a long history of experiencing a change in character that damages the authenticity and uniqueness of the city, the heritage of the city and its cultural heritage. This study aims to find the spatial pattern of Ternate city, with the approach of spatial morphology, so that the conditions of the original space and its changes can be found. The method used is literature study in the form of old maps and new maps, comparing changes in space from time to time, analyzing the diachronic and synchronic processes of change to find spatial structures so that they can be used as references in the city's architectural preservation efforts. Keywords: morphology, character, city, Ternate

Pumice sand is a bright colored butian type, containing foam made from glass-walled bubbles andusually referred to as silicate volcanic glass granules. This pumice sand can be used as a substitutefor normal sand as fine aggregate in a mixture of concrete mix. Based on the characteristic testexamination, it can be seen that in testing the characteristics of pumice sand to the specificationsof normal sand in specific gravity testing and weight testing of quicksand obtained results thatare smaller than the specifications of normal sand and absorption tests obtained results greaterthan specifications on normal sand. The results of the normal sand compressive strength at BN is250.95 kg /cm2 while the results of the floating sand concrete compressive strength on BPA is224, 965 kg /cm2. Based on the research it can be concluded that with the same quality of concrete,the quality of K-250 is different in comparison to the compressive strength of concrete in normalsand and pumice sand concrete shows almost the same results. Therefore, more in-depth researchis needed regarding the use of pumice sand instead of normal sand in a mixture of concrete mix.

Iron sand is a natural resource that many found in North Maluku one of them in Yao Village District Morotai Island. Iron sand mining results have the potential to become an Indonesian commodity but iron sand processing is still not maximized at this time. The purpose of this research is to know whether the sand of Yao Village including iron sand, To know the effect of iron sand usage as fine aggregate on the mortar mixture against compressive strength and against absorption. In this research, the test of compressive strength and mortar absorption. This research uses fine aggregate substitution material is Yao Village sand. Preparation of specimen with Fas 0,40, Yao Village sand composition as substitution of fine aggregate that is 0%, 20%, 40%, 60%, 80% and 100% to the fine aggregate weight. The composition of Sand Yao Village after the most dominant purification was Fe (75.84%) of the total iron ore content, followed by Si, Ti, Ca, Al, and other minor elements, so it was classified as an iron sand. There is a decrease in compressive strength along with the increase of iron sand composition 0%, 20%, 40%, 60%, 80% and 100%. Large decreases in compressive strength of each s 19.20 MPa, 19.00 MPa, 18.60 MPa, 13.00 MPa, 13.00 MPa and 12.36 MPa. absorption of mortar in 20% iron sand substitution and 40% of absorption increased, at 60% composition decreased.

Sustainable water resources management system is a water resources management system that is designed and managed and fully contributes to the community (social and economic) for present and in the future, while maintaining the sustainability of its ecological aspects.This research was under taken by direct observation in the field. Then the data obtained from the field is processed using a computer program. This research activity was carried out in Wasile Timur Village, East Halmahera Regency, North Maluku Province. The results of this study indicate that the diameter of the pipe used is diameter 300 mm, 250 mm, 200 mm, 150 mm, 100 mm, and 63 mm. Based on the variation of the pipe, the maximum pressure is 49.37 m or equal to 4.937 bar while the minimum pressure is 26.39 m or equal to 2.639 bar. As for, the pressure from the results of the analysis meets the distribution network planning criteria, namely a maximum of 9.0 - 12.4 bar and a minimum of 0.5 - 1.0 bar. Maximum flow speed of 0.60 m / s and minimum speed of 0.30 m / sec flow velocity. Analysis results is showed the planning criteria which according to the provisions is a maximum of 2.5 m / sec and a minimum of 0.25 m / sec.

The position of Ki Hadjar Dewantara road is strategic location, where as an education center, office and residential center are often happened to increase in vehicle volume, especially during peak hour, consequently, this condition makes congestion on this road. There are ideas for road widening, moved side barriers and one.way traffic management, which are purposing to know traffic performance currently and generating a recommendation of traffic systems. By observations on traffic surveys were carried out on the road at 06.00 to 18.00 WIT. Traffic performance analysis is based on the 1997 Indonesia Road Capacity Manual (MKJI). The results of the Ki Hajar Dewantara road analysis showed a high level of side resistance with a value of degree of saturation (DS) in segment 1, which was 0.78, free flow speed of 31.2 km / hour, road capacity of 1953 pcu / hour. Furthermore, as an alternative solution the application of a one way system on the road section that showed a better performance with DS = 0.32 for west to east and DS = 0.22 east to west with a service level B category with stable current, speed slightly limited by traffic, the driver has enough freedom to choose a speed. The design for implementing this one-way system is good for solving problems.

Ternate Region which was once the center of European power in the archipelago before being transferred to Jakarta by Governor-General Jan Pieterzen Coen. (1619-1623), who later renamed Batavia, was the V.O.C (Dutch East Indian Company) headquarters, the world's first multi-national company, for Southeast Asia centered on the Orange fortress Ternate. Orange fortress built by Cornelis Metalief de Jonge in 1606-1609. V.O.C. which recorded putting his governor in Ternate as many as 55 people from 1607 to 1810, depart from this history so up to now, the existence of Dutch buildings in the city of Ternate can still be found. The method used in this research, is a qualitative descriptive method that focuses on the overall description of the form, function, and periodization associated with the legacy of the Dutch Colonial Architecture in Ternate. The existence of colonial architectural heritage in Ternate becomes very important to maintain the existence of Ternate as one of the regions that have historical value in Indonesia. In order to support it, this research process becomes very important for the development of architectural science in Ternate City and the general contribution of this research is expected to complete the documentation about the development of the city of Ternate not only in terms of its history but in terms of its architectural wealth

The existing water resources need to be sustainably managed. Sustainable water resource management system is a managed and managed water resources management system that fully contributes to current and future societal and economic goals while maintaining its ecological sustainability. This research was conducted by direct observation in the field. Then the data obtained from the field in though by using a computer program. This research activity was conducted in East Wasile Sub-district of East Halmahera Regency of North Maluku Province. The results of this study indicate that the diameter of the pipe used is 300 mm diameter, 250 mm, 200 mm, 150 mm, 100 mm, and 63 mm. From the variation of the pipe obtained Maximum pressure 49.37 m or equal to 4.937 bar while minimum pressure of 26.39 m or equal to 2,639 bar. The pressure of the analysis result meets the criteria of distribution network planning that is maximum 9.0 - 12.4 bar and minimum 0.5 - 1.0 bar. Maximum flow velocity of 0.60 m/s and a minimum speed of 0.30 m/s flow velocity on the analysis results meets the planning criteria which according to the provisions of a maximum of 2.5 m/s and a minimum of 0.25 m/s.
