Abstract

In the North Maluku Province, specifically in the Kao Barat District of North Halmahera Regency, there is the Wai Lamo River which flows through five villages: Pitago Village, Bailengit Village, Soamaetek Village, Parseba Village, and Tuguis Village. These villages are often affected by flooding due to the river's overflow during heavy rainfall. The purpose of this study is to model the flooding caused by the overflow of the Wai Lamo River, especially in these five villages, and to assess the extent of the flood-affected area. The flood modeling method uses a hydrological approach to simulate water discharge in the river using the HEC-HMS software, and flood inundation areas and affected zones are visualized using GIS with HEC-RAS software. The flood discharge rates obtained from hydrological analysis using HEC-HMS (Hydrologic Modeling System) for return periods of 2, 5, 10, 20, 50, and 100 years at the flood-affected village control points are 115.8 m³/s, 324 m³/s, 550.2 m³/s, 848.5 m³/s, 1376.6 m³/s, and 1897 m³/s, respectively. The results of flood inundation modeling using HEC-RAS (River Analysis System) based on the return period floods show that the overflow of the Wai Lamo River impacts Pitago Village, Bailengit Village, Soamaetek Village, Parseba Village, and Tuguis Village due to their proximity to the riverbanks. Therefore, river embankments and riverbed normalization are required to protect the settlements from the overflow of the Wai Lamo River.

Abstract

Utilizing nutmeg pulp into essential oil is an effort to maximize the potential of nutmeg flesh which has so far only been a waste. The content of functional compounds in nutmeg pulp oil can enrich the taste of food products and even provide health benefits. The aim of this research is to examine the effect of essential oils from nutmeg flesh as a natural flavoring agent on the sensory profile of cakes. The experimental design used was a Completely Randomized Design (CRD) with treatment concentrations of nutmeg pulp oil, namely 0%, 0.05%, 0.10%, and 0.15%. The sensory profile observed included color, aroma, taste, and texture. Data were analyzed using ANOVA and continued with Duncan's Multiple Range Test (DMRT) if there were significant differences. The results showed that different concentrations of nutmeg pulp oil affected the aroma, taste and porous texture of the cake, but had no real effect on the color and soft texture of the cake. The addition of nutmeg pulp oil as flavouring agent produces a cake with a bright yellow color, a slightly fragrant aroma typical of cake to a typical cake aroma, no nutmeg aroma to nutmeg aroma, the taste is close to sweet to sweet, the texture is soft and the pores are quite tight. The sensory profile of a cake with the addition of nutmeg pulp oil has the same sensory characteristics as a cake without the addition of nutmeg pulp oil, namely a cake with the addition of 0.05% nutmeg pulp oil.

Abstract

Water quality is the main factor in developing a clean and healthy lifestyle (PHBS). Researchers in this study wanted to see the quality of water sources used by the people of Hatalai State. Hatalai Country is a country that is 5.9 km from Ambon City Center, with a population of 989 people, with steep conditions. However, it has quite a number of springs. There are many springs where water is used by the people of the country. For this reason, researchers feel it is necessary to conduct research on the physical quality of five water sources, with the aim of this research being to identify the physical conditions of water storage and distribution facilities, analyze the physical quality of water and provide recommendations for providing clean and healthy water. Research methods. This research uses a descriptive approach and laboratory analysis. Researchers made observations on the condition of the distribution, storage and utilization of water at the research location. Samples were taken in holding tanks from 5 springs which will then be analyzed in the laboratory. The research results show that according to quality standards, water that is good for PHBS and drinking has no taste. Testing for turbidity parameters in Alam, Wermaang, Tree Damar, and Waisaru water has met the water quality standard requirements because it does not exceed the maximum level of <3 NTU. The turbidity test results for water in Hatalai ranged between 0.27 - 0.33 NTU, meaning that water that is not turbid contains very little dangerous substances such as iron and manganese. In conclusion, the water quality in Hatalai State physically meets the health requirements for consumption. The reservoirs are all in good condition.

Abstract

The city of Ternate is a small city on a quaternary volcanic island with a strato volcano type that develops in the Halmahera island area as part of the Pacific circumference. The city of Ternate, as a small city that continues to develop, has complex problems related to limited building space and the potential threat of very diverse natural disasters. Tubo Village is one of the areas that is a potential threat point from the Gamalama volcanic eruption. The Tubo sub-district area is part of the succession of mature to old Gamalama volcanoes which have episodes of Gamalama volcanic eruptions, including direct eruption impacts in the form of laharic material, volcanic ash and lava flows. Tubo Village also has a history of the impact of volcanic eruptions in the form of laharic floods which have had an impact on physical victims and fatalities. Disaster Resilient Village is one of the best solutions that must be implemented with the aim of building the preparedness of Tubo residents to face volcanic eruption disasters. This initiation program is a collaboration with Pertamina FT Babullah and the Ternate City Government.

Abstract

Ternate City is the most densely populated area both demographically and building, this causes the need for clean water to increase, by looking at the geological structure of Ternate City which is most of the area is rock, of course it is an obstacle in itself in meeting the need for clean water The purpose of the activity is to obtain an overview of the availability and potential of groundwater that can be exploited in the study area, so that it can be used as an alternative to raw water supply planning. with indications that there is water at a depth of 160 to 190 meters, Based on the character pattern of the constituent rocks, there are sandstones, and tuff and subsurface contour patterns. Red, There are andesite rocks in the form of lava and brexi andesite. Dark Green – Light Green, There are clay rocks, this type of rock is included in impermeable rocks Orange Color: There are laharic brexi rocks, in this position it is very unlikely that water can be trapped, because laharic brexi is a lateral rock deposit, while clay is the opposite, which is characterized by impermeabl rocks, Blue Color, It is a puddle of surface water at a depth of 10 to 20 meters.

Abstract

The eruption activities of Gamalama Volcano produced various volcanic materials which ultimately became a geological diversity on Ternate Island. Where the identified geodiversity consists of rock types, landscapes, beaches, hot springs and underwater geology which are very beautiful and interesting. In an effort to support the development of geotourism activities in the Aspiring Ternate geopark area, research is needed regarding the use of geological diversity, especially in the Batu Angus Geotrail, to provide an overview of how it can be utilized in geotourism activities and at the same time create opportunities for economic growth. This research uses a qualitative approach utilizing the inventory of geological diversity issued by the Geological Agency, 2017 with mapping and field observations related to geological diversity and its use in geotourism activities. The geological diversity resulting from the eruptive activity of Mount Gamalama, namely producing aa lava flow, blocky lava, spatter cone, spatter vent, lava tumuli, hornito lava, lava tube, channel lava, blocky lava flow, blocky lava smoother, accreted lava, lava walls and fracture. The geological diversity contained in the Batu Angus Geotrail is used for geotourism activities in the form of trekking activities, sport tourism activities (trail running, jogging, gymnastics, yoga), adventuring, research activities, jeep tours, Geo-Edu (field trips and excursions), art attraction stages & culture and conservation activities. Utilization of the geological diversity of eruption products from Mount Gamalama provides opportunities for local communities and regional governments to develop sustainable tourism activities in the form of geotourism.
