Pedada fruit (Sonneratia alba) is a fruit of mangrove plants whose utilization can be improved through simple technology, namely the processing of Sonneratia alba fruit into syrup. Mangrove plants produce fruit that can be utilized as a processed beverage, one of which is Sonneratia alba fruit that has a sour taste and can be processed into fresh drinks in the form of mangrove syrup. The purpose of the study was to find out the nutritional value content of mangrove syrup from Sonneratia alba fruit. Research methods are experiments. We use proximal analysis, which includes tests on protein, fat, carbohydrate, and vitamin C. Proximal analysis is carried out at the organic chemistry laboratory, Faculty of MIPA Universitas Jenderal Soedirman. The results of our research show Processed mangrove syrup from Sonneratia alba fruit has nutritional content: protein 1.20%, fat 0.20%, carbohydrates 3.50%, and vitamin C 55.30%. Mangrove fruit from Sonneratia alba processed into syrup has a high nutritional and antioxidant value and is rich in fiber, which is good for health

Ecologically Invasive Aliens Species (IAS) poses a particular threat to the conservation area that is a biodiversity sanctuary, Baturraden Botanical Garden (KRB). The purpose of this research is to find out the composition of IAS in KRB. This method of research is a survey method with purposive random sampling. Observation and prosecution is done by dividing krb into 10 plots. Information on the introduction process as well as conservation strategy recommendations is obtained through library studies and interviews with resouce person. The data then analyzed using the Importance Value Index (INP). The results showed that the IAS introduction process began in 1952 through the utilization of Protected Forest (HL) and Limited Production Forest (HPT) in KRB; The vegetation community structure in the KRB is dominated by spikes (saplings), seedlings, trees and poles. There were 13 IAS species consisting of 9 families; Seedling and saplings Calliandra houstoniana var. calothyrsus (Meissner) Barneby and Agathis dammara (Lamb). Rich. while at Agathis dammara (Lamb) tree level. Rich. and Schima wallichii Choisy. potential as a special IAS in the KRB; Controlling can be done through mitigation, periodic maintenance and eradication. In situ and ex situ conservation strategy plans in KRB are the creation of forest pharmacy conservation villages.

The objectives of this research are: (1) To know the effectiveness of lowering the rate of liquid waste COD stamp batik. (2) To know the most effective dose of the EM-4 in lowering the COD levels of liquid waste of stamp batik. (3) To know the day of how many EM -4 is most effective in lowering COD's liquid waste stamp batik. The study used the complete random design of the factorial pattern of dosage EM-4 0 ml/L, 10 ml/L, 15 ml/L and prolonged incubation for 1 day, 2 days, 3 days. The Data obtained is analyzed using two-lane analysis (Two Way Anova). Based on the results of the analysis of the treatment EM-4 and the old incubation against the liquid waste stamp batikobtained the following results: At a group of doses acquired F count = 4209.382 > F table 5% = 3.55, then H0 rejected or there is a real influence of various doses of EM -4 which is used against COD levels. At the time group gained F count = 77.756 > F table 5% = 3.55, then concluded that there is a real influence of incubation time against the rate of COD waste car stamp batik. The most effective EM-4 dosage to lower COD levels of liquid waste stamp batikis 15 ml/l which is capable of lowering COD levels by 96.24% and the most effective prolongedincubation time is the first day. Keywords: Effectiveness, Prolonged incubation, EM-4, COD, Waste batik stamp.

Peat water has a brown color, humic acid content, organic substances, iron and pH levels are very high. To overcome the problem of peat water to be made clean water need to be processing first. Continuous processing of peat water includes; Neutralization, aeration, coagulation – flokulation, and filtration is a complete set of processes but is packaged in a simple form. This process is designed according to the condition and level of education of rural communities in peat water treatment. This study was conducted at a shelter in the village of Peunaga Cut Ujong Meurebo West Aceh. This research aims to reduce acidity, color, turbidity, flavor, iron (Fe), Zeng (Zn), organic matter, nitrate (NO3), and Nitrit (NO2). The research method is an experimental that is directly applied in the field. From the laboratory results in the UPTD Health Banda Aceh has been conducted test water quality before and after processing there are significant results. The results of experimental studies through the simple design of continuous processing using natural materials such as gravel, sand, charcoal and palm fiber and the chemical filling of the capor and alum obtained the results of color dissipation achieved 93.3%, pH of 98.3%, turbidity/cloudiness reached 91.9%, organic substance (KMNO4) of 73.3%, hardness of 39.7%, iron (Fe) 94.6%, zinc (Zn) of 91.09%, Flurode 77.33%, Nitrate (NO 3) of 80.04%, and Nitrit (NO 2) 99.31%. Meanwhile, the result of peat water is no smell and feel. The results of this trial are still under the standard quality of Permenkes RI No. 416/Menkes/PER/IX/1990 on the water quality requirements.
