Abstract

Kolongan Village is one of the villages in Talawaan district of North Minahasa, North Sulawesi. In the village of Kolongan, some springs are potentially a clean water source for the people of the village. This research aims to analyze the quality of the springs in the village of Kolongan Talawaan, Prefectures as a water source. This type of research is quantitative, and the method used in this research is the Indonesian National Standard (SNI) according to the water quality parameters that have been established with the direct observation plan of the physical properties of water and with the laboratory testing plan for the observation of water chemical and biological properties with indicators of iron, sensitivity, manganese, E.coli, taste, and smell. The research was conducted from July 24, 2021, to September 20, 2021. The water quality measurement results in the spring in one village of Kolongan showed iron <0.0086 mg/L, iron 69-93 mg/ L, manganese 0.03-0.07 mg / L, E. coli, 11 CFU, not sensitive and odorless. Water source 2 showed iron <0.086 mg / l, density 75-85 mg/ l, manganese 0.02-0.03 mg/l, and E. coli, 3.6-9.2 CFU, is not sensible and odorless. The pollution index calculation indicates that the springs in Kolongan Village belong well. However, because they still contain biological reservoirs, it is necessary to have an advanced process for them to be consumed by the community.

Abstract

The Yaki monkey (Macaca nigra) is a critically endangered endemic species of North Sulawesi and is listed in Appendix II of CITES as well as in-situ conservation at the Tangkoko Conservation Forest Management Union (KPHK Tangkoko). The public's knowledge of the conservation of M. nigra is a key factor inining the sustainability of this species. The aim of this research is to find out the level of public awareness about conservation of M. nigra. This research uses descriptive methods. Data collection is done with a questionnaire with scored using the Guttman scale. The results of this study show that the majority of the level of knowledge in the community in the buffer zone KPHK Tangkoko belongs to a level of good, sufficient, and insufficient to the conservation status of m. nigra. Respondents who have good knowledge are all respondents in the Batu Putih Bawah villages and Duasudara villages. While the majority of the population in the Kasawari villages (63%) and the Pinangunian villages (68%) have sufficient knowledge about the conservation status of the M. nigra while almost half of the Kasawari villages (37%) and Pinangunian villages (32%) have insufficient knowledge.
