Abstract

The feasibility study of the location of seaweed cultivation is very important to be carried out in order to ensure the sustainability of the cultivation activities in question. Therefore, this study aims to examine the feasibility of the technical aspects of seaweed cultivation to support the development of seaweed cultivation in the coastal waters of Mengumfoka Village and Kaki Island, Manokwari Regency. The research method is the observation method with survey techniques (in situ and ex situ). The results showed that the two research sites had characteristics of the physical-chemical and biological conditions of the waters that could support seaweed cultivation activities. Location KA1 has a score of 86.2, which means the location is highly suitable, while location KA2 has a score of 75.4 or moderately suitable as a location for seaweed cultivation. In general, KA1 and KA2 locations have the same conditions, but KA2 locations are more open than KA1 locations, so that KA2 locations have more risk due to large currents and waves due to seasons. So the location of KA2 can only do seaweed cultivation during the shady season.

Abstract

The construction of bridges and the Trans Papua Mameh-Bintuni road section of West Papua Province crosses rivers (Mothy-I Bridge), (Mothy-II Bridge), and (Yuki-II Bridge). The impact of this development is estimated to affect a decrease in river water quality and pollution. River water quality criteria are determined based on the pollution indicator. Water quality samples were taken from rivers directly affected by bridge construction activities and the Trans Papua Mameh-Bintuni road preservation. Water quality parameters and river water sampling refer to SNI 6989.57:2008. Water sampling was carried out after the construction activities were completed. The results showed that the water quality in the three rivers met the class II river water quality standards according to Government Regulation No. 22 of 2021. The Pollution Index of rivers (Mothy-I Bridge), rivers (Mothy II Bridge), and rivers (Yuki Bridge II) each has a Pollution Index value of 0.769; 0.816; and 0.770. This value describes the water quality in the three rivers in the excellent category, qualify environmental quality standards. Biological, chemical and physical indicators are in the natural concentration value, thus the bridge construction activities and the preservation of the Mameh-Bintuni road in West Papua Province that have been carried out do not have a negative impact on changes in river water quality.
