Lake Matano and Towuti in South Sulawesi Province are two of 15 priority lakes in Indonesia that need to be preserved from degradation. C to 30.5 The water quality parameter factsheets were developed to provide an introduction to monitoring common parameters; Temperature, Dissolved Oxygen, pH, Turbidity, Macroinvertebrates, E. coli, Nutrients, Habitat Assessment and Metals. There is great range in the surface area and depths of these lakes, and some variance in their water chemistry. Tsunamis are one of the most frequent deadly natural disasters in Indonesia. Relatively high ammonia concentration in control without plant treatment (aquarium A) affected the growth of freshwater crayfish. The goal of this study is to better understand the sediments structure of Lake Towuti that layered above East Sulawesi ophiolitic and metamorphic rocks for stratigraphic interpretation. Siderite C-O-Fe isotope compositions, pore water geochemistry and bulk sediment measurements covering the 100 m-long core from drill site TDP-1A in ferruginous Lake Towuti, Indonesia. Forecast for the next few days - The weather forecast for Lake Towuti is available in several of 200 m, there was small fluctuation on water pH due to less affected of terrestrial activities of land and it only resulted from activities of organism that exist in this depth Lake Towuti (Indonesian: Danau Towuti) is a lake in East Luwu Regency, South Sulawesi province, Indonesia. According to Nasution 2004 range temperature of Lake Towuti from March 2002 to April Shrimp that are found within the river are not thus considered riverine, as it is considered an extension of either lake rather than a true river. The maximum and minimum operating levels of Lake Towuti are 319 .6 meters (asl) and 317.45 meters (asl) respectively. Lake Towuti has extremely high rates of floral and faunal .

At 164.1km, its surface area is less than that of Lake Towuti, however. N2 - We investigated the mineral-magnetic behavior of sediments from Lake Towuti located in the Eastern Sulawesi Ophiolite belt, Indonesia. Careful examination demonstrates that these zones correspond to varying levels of iron oxide dissolution and magnetite precipitation that are climatically and environmentally dependent. Continental Scientific Drilling Facility; 2 3 Rainfall fluctuations in October slightly increased compared to in September and November. The data include parameters of paleolimnology with a geographic location of Indonesia. The results show that the core has three distinct zones of varying magnetic properties. tropics ranges between 25 Stagline (Wellington) should be cited as Stagline (Wellingt.) o Water temperature regulate the metabolic processes of living organisms in the water,such as fish. The following models are available for Lake Towuti: 175 200 The sediments beneath the lake's waters date back a million years or more and could . et al Although our data show that major changes in concentration dependent parameters, such as magnetic susceptibility and saturation isothermal remanent magnetization (SIRM), in Lake Towuti sediment correlate with changes in regional rainfall, many of the concentration changes are more strongly affected by in situ chemical processes than by changes in erosion and terrestrial sediment supply. Dissolved oxygen content varied broadly and it ranged from 0.15 - 6.60 mgL. Those characters were Total length (TL), Pre-dorsal Length (PDL), Pre-pelvic Length (PPvL), Length before Anal fin (LBAF), Head depth (HD), Body Depth (BD), Depth of caudal peduncle (DCP), Upper jaw length (UPL), Lower jaw length (LJL), Eye diameter (ED), Length of dorsal fin base (LDFB), Pre-anal Length (PAL), Pre-pelvic Length (PPvL), Length of pectoral fins (LPF), and Length of tail fin (LTF), the number of circular scales on the caudal peduncle (CSCP), the number of branched dorsal fin rays (D), and the number of branched pectoral fin rays (P).

Odum 1972 said that, dissolved oxygen in water is a main factor for the metabolic processes in aquatik These five lakes are: Lake Matano (the northernmost lake) is connected by the Petea River to Lake Mahalona, which in turn is connected to Lake Towuti by the Tominanga River. D ep This output contributes to the following UN Sustainable Development Goals (SDGs). As mentioned, Lake Matano is the northernmost lake of the Malili lake system. Djadjadiredja and Djangkaru 1980 said the life of freshwater fish in intensive aquaculture would be better if the dissolved oxygen content of more than 5 mgL. It may resulted of the effect of activities in the terrestrial. Although our data show that major changes in concentration dependent parameters, such as magnetic susceptibility and saturation isothermal remanent magnetization (SIRM), in Lake Towuti sediment correlate with changes in regional rainfall, many of the concentration changes are more strongly affected by in situ chemical processes than by changes in erosion and terrestrial sediment supply. The data were subjected to the Kruskal Wallis analysis and continued with Mann Whitney test, Principal Component Analysis, and Unweighted Pair Group Method Average Arithmetic.

At a depth Archaeological evidence from survey and cave excavation in the Towuti-Routa region of Sulawesi suggests the following sequence of late Holocene cultural change. The sampling was conducted from June to October 2009 at seven sampling locations in the Lake Towuti, namely Tominanga, Manu Cape, Loeha Island, Hola-hola downstream, Kawatang downstream, Beau and Bakara Cape. Surrounded by mountains, it is the largest lake of the island of Sulawesi and one of the five lakes of the Malili Lake system (the other being Matano, and the small Mahalona, Masapi and Lontoa (Wawantoa)). The total fishing effort would soon put pressure to the LRF resources. The water quality parameters obtained are as follows Temperature: 26.40C-30.30C, pH: 6.35-9.03, dissolved oxygen (DO):6.25-8.95 mg/L and NO3-N: 0.023-0.066 mg/L.This water quality were suitable for the survival and growth of endemic fish. 6 Lake Towuti (Indonesian: Danau Towuti) is a lake in East Luwu Regency, South Sulawesi province, Indonesia. This is due to its large surface area of 561.1km. 6 1 the Malili lake species flock. The magnetically strongest zone is characterized by weak iron oxide dissolution and intense magnetite precipitation, likely driven by changes in the stratification and/or water level of the lake during dry conditions in Marine Isotope Stage 2 (MIS2) period, whereas the two magnetically weaker zones are characterized by signs of dissolution and correspond to relatively wet conditions, respectively, during Marine Isotope Stage 3 (MIS3) and the Holocene. 2075-B S.
