Abstract

North Maluku is rich in marine biodiversity, including small pelagic fish such as julung-julung fish (Hemirhamphus sp.), which are often processed into sambal roa, a traditional chili sauce made from smoked fish and spices. This product is well known as a traditional food and regional souvenir, but traditional processing methods result in a short shelf life and vulnerability to microbial contamination. This study aims to determine the effect of sterilization duration on F₀ value, and organoleptic quality of canned sambal roa. The research was conducted using a completely randomized design (CRD) with four sterilization times at 121°C: 15, 20, 25, and 30 minutes. The results showed that F₀ values increased with longer sterilization times, reaching the highest value of 6.02 minutes in treatment P4 (30 minutes). Organoleptic tests revealed the highest scores in treatment P4 for color (7.88), taste (8.46), aroma (7.67), and texture (8.13), all of which were in the "highly liked" category. hus, sterilization for 30 minutes in the canning process significantly improves the safety, shelf life, and sensory quality of sambal roa, making it a promising traditional commercial product from North Maluku.

Abstract

The hydrogeological characteristics of small volcanic islands possess unique attributes. Groundwater flow patterns descend radially and converge in coastal aquifers. The uneven distribution of coastal aquifers sometimes leads communities to extract groundwater from specific points. A notable phenomenon observed in the study area is the presence of dug wells with multiple water pumps. If the combined suction capacity of these pumps exceeds the allowed limit, it has the potential to cause the mixing of saltwater with freshwater. This study utilizes geoelectric methods to delineate the groundwater-saltwater interface beneath the surface. The groundwater-saltwater interface can also be calculated using equations. By knowing the well positions with multiple pumps, it is possible to calculate the allowable number of pumps. The calculations yield a limit of up to 31 pumps per dug well, thereby mitigating the risk of saltwater intrusion. Furthermore, data on the dug well positions within the study area are used to create groundwater table contours and flow models, aiding in the analysis of saltwater pollutant dispersion in the event of intrusion.

Abstract

One source of raw water that is often used by humans is groundwater, namely water that occupies cavities in the layers of rock beneath the earth's surface. Groundwater is often used as a source of raw water or a source of clean water by the community apart from river and lake water. Each region has its own level of groundwater potential that can be utilized. The purpose of the analysis carried out is to determine the distribution of potential groundwater in each sub-district area in Gowa Regency through the use of a Geographic Information System (GIS), by applying the overlay method to a number of variables which are factors that influence the presence of groundwater, such as slope, use land, soil type, geology, and rainfall. The results of the analysis that has been carried out show that Gowa Regency has groundwater potential that is spread over each of its sub-districts, where it is divided into a number of potential levels of groundwater availability starting from very low, low, medium, high, and very high.

Abstract

Diarrhea is a major cause of morbidity and mortality in all age groups and regions in the world. Environmental factors and drinking water are risk factors for diarrhea. it is important to examine the influence of environmental hygiene factors and drinking water on the incidence of diarrhea. Therefore, this study presents information regarding the influence of environmental cleanliness and drinking water on diarrhea by reviewing empirical studies in previous and current research. In order to identify the influence of environmental cleanliness and drinking water factors on the incidence of diarrhea, a review of literature collected from the PubMed, Scopus, Google Scholar databases in English and Indonesian was carried out. Literature taken from the last 10 years, namely from 2014 to 2024 and in the form of full text publications. Environmental sanitation factors and good drinking water play an important role in determining how susceptible a person is to gastroenteritis or diarrhea. The availability of clean drinking water is the most important factor in preventing diarrhea. Lack of clean water has emerged as one of the main factors causing diarrhea. Access to proper and clean drinking water is obtained from protected drinking water sources, including tap water (taps), public hydrants, public taps, water terminals, rainwater reservoirs or protected springs and wells, drilled wells/pumps that are at least a distance away 10 meters from waste disposal facilities can prevent diarrhea.
