Abstract

This study aims to describe the profile of vegetation diversity in the mangrove ecosystem in Tamuku Village, Bone-Bone-Bone District, North Luwu Regency. This research is a qualitative research using survey methods. The data collection technique uses the Quadrant Line Transect Survey technique. The data analysis technique uses the thinking flow which is divided into three stages, namely describing phenomena, classifying them, and seeing how the concepts that emerge are related to each other. The results of this study are the profile of mangrove vegetation in Tamuku Village, which is still found 16 varieties of true mangrove vegetation and 7 varieties of mangrove vegetation joined in the coastal area of Tamuku Village, Bone-Bone District, North Luwu Regency, South Sulawesi. The condition of mangrove vegetation in Tamuku Village is currently very worrying due to human activities that cause damage such as the project of normalization of flow, opening of new farms, disposal of garbage, water pollution due to chemicals, and exploitation of mangrove forests for living needs. The impact is ecosystem damage and reduced vegetation area as a place to grow and develop mangroves.

Abstract

This study aims to determine the effect of mangrove habitat on the level of lead (Pb) contamination and its effect on the quality of water, soil and fish in the waters of the Tallo River estuary. This research is a descriptive type of research using survey methods. This research was carried out by taking samples of water, fish, soil at three stations namely, Station I Mangrove Forest area, Station 2 Tallo River Estuary and Station 3 Port of Paotere. The results of this study indicate that lead (Pb) pollution along the waters of the Tallo River, has exceeded the water threshold of 0.01725 mg /l, fish 0.05615 mg/kg and land as much as 36.113 mg/L according to Rangkuti (2009). In addition, from the linear regression test it was found that lead had a significant effect (F> 0.05) on pH and salinity. However, lead has no significant effect (F <0.05) on temperature, dissolved oxygen, ammonia, nitrite and plankton.

Abstract

This study aims to determine the effect of the method and duration of processing on the analysis of the quality of orange sweet potatoes (Ipomoea batatas L). The study used a randomized block design consisting of two factors, namely the processing method and the duration of processing carried out three times. The treatments in the study were processing methods (steaming and frying) and duration of processing (5 minutes, 10 minutes, and 15 minutes) with a heating temperature of 100 ° C. Observation data were analyzed using Variety Analysis (ANOVA) then continued with Duncan Test. The results of the study showed that the interaction of the processing method variables and the duration of processing were not significantly affected. Beta-carotene, anthocyanin, fiber content, color and taste are only influenced by processing methods and duration of processing, while texture and aroma are only influenced by duration of processing . The best treatment of the method and duration of processing of orange sweet potato (I. batatas L) was by steaming method for 15 minutes with beta-carotene (0.07%), anthocyanin (8.99%), fiber content (0.93%) , color and aroma (rather like), and texture and taste (likes).
