Abstract

Penerapan kembali tradisi budaya mulung memberi dampak positif bagi habitat sumber daya perairan dikawasan peraiaran yang menjadi lokasi mulung. secara harafiah mulung terbagi dalam dua tahap pengelolaan. tahap pertama adalah prosesi adatia hading mulung pada tahapan ini kawasan peraiaran ditutup atau dilarang untuk sementara waktu dari aktivitas penagkapan atau pengambilan sumber daya melalui ritual adatia. pada tahap kedua adalah hoba mulung pada tahap ini diadakan prosesi adat pencabutan larangan sehingga kawasan mulung dapat dilakukan pengambilan atau penangkapan sumber daya perairan. interval waktu antara hading mulung dan hoba mulung memberikan kesempatan kepada alam untuk pulih. kondisi ini berdampak pada pemulihan habitat sehingga populasi sumber daya menjadi limpah. seturut melimpahnya sumber daya perairan seperti ikan berkorelasi positif terhadap volume penangkapan nelayan dan implikasinya pada saat penjualan, dalam hal ini pedagang ikan pun menerima manfaatnya dengan bertambah jumlah pendapatannya. metode survei digunakan untuk mengukur dampak mulung (konservasi habitat sumber daya periaran) terhadap peningkatan ekonomi masyarakat pesisir (nelayan dan pedagang) baranusa, menggambarkan pendapatan nelayan yaitu Rp. 6.400.000. selain itu pedagang juga mengalami peningkatan pendapatan sebulan berkisar Rp. 1.500.000 sampai dengan Rp. 6.000.000.

Abstract

The palm oil industry liquid waste is rich in organic materials and thus it can be used as media to grow Chlorella sp. This algae needs organic materials for growing, and it may decrease the organic material contents in the waste. To understand the best concentration of palm oil industry liquid waste to grow that algae, the chemical composition of the algae reared in different concentration of waste, and to understand the organic materials decrement in the waste, a study has been conducted in April – May  2019. There was a CRD applied. The waste was mixed with aquadest in   5 different concentration, namely    P1 (0%), P2 (15%), P3 (20%), P4 (25%), dan P5 (30%). Results shown that the best algae population was in the   P4 (4.64 x 106 cells/mL), the best biomass was in P3 (0.77 gr/L) in the 12nd day culture.  The P0 provide the best results on fat (12.5%) and carbohydrate (24%) but shown the lowest of protein (16%), DO (1.10 mg/L) and chlorophyll-a (0.140 mg/L) and provide the worst CO2 content (8.77 mg/l). P3 shown the highest content of protein (45%).   P4 shown the highest chlorophyll-a concentration (0.403 mg/L) and O2 concentration (9.94 mg/L) and the lowest CO2 (2.75 mg/l). The P4 also shown the best result in decreasing organic materials content. Nitrate reduced, from 14.3 mg/L into 3.1 mg/L, while Phosphate reduced, from    1.87 mg/L to 0.33 mg/L respectively. In all treatment, the water temperature ranged from 280C to 300C and the pH was   6.33 – 9.50.

Abstract

Environmental carrying capacity with the other methods has been used by other countries especially developed countries. One of method was based on ecosystem services which developed by MEA in 2005. This approach looked environmental carrying capacity through benefits that people could get on it. In the other hand, environmental carrying capacity based on ecosystem service could integrated in spatial urban regional planning or other developing plan. Ecosystem services are benefits that humans getfrom ecosystems. Sustainable development era has increased demand on ecosystem services information to be incorporated into various development policies and planning. This research Purpose to assessing spatial distribution of ecosystem services for clean water supply as basis of management for sustainable resources. The research method was an ecosystem service approach using two estimating variables, land cover and ecoregion as the landscape ecosystem. Each estimator variables assessed of Ecosystem services by expert judgment with coefficient values. This research specifically discusses the comparison of the results of maps of ecosystem services formulated through experts' judgement on land use based proxy and a combination of land cover and ecoregion. We use Analytical Hierarchy Process (AHP) with pairwise comparison method to asssess the potential of ecosystem services from land cover and ecoregion. The case study area is south tapanuli district, while the type of ecosystem services analyzed is type of clean water supply. The results of the calculations show that the index of ecosystem services resulting from acombination of land cover and ecoregion produces a more accurate map of ecosystem services with qualitative information. The coefficient values were processed and analyzed by using GIS technique to produces spatial distribution of Ecosystem Services values which were divided into five classes of the ecosystem services : very high, high, medium, low, and very low. The results showed that south tapanuli district have great potentials to provider the ecosystem services for clean water supply with medium to very high class value of ecosystem services (36,17% of the South Tapanuli District).

Abstract

This research was conducted on 27 April-30 May 2019 at Tiram Beach, Karambia Ampek Beach and Gosong Beach, Padang Pariaman Regency, West Sumatra Province. This study aims to determine the relationship between sediment grain size and the number of turtle eggs. The method used in this research is purposive sampling. The sampling location is divided into 3 stations, each station is divided into 5 sampling points in order to obtain 15 sampling points, of which the fifteen sampling points are the usual nesting sites for turtles. Sediment samples were taken approximately 500 grams, put in a plastic bag, then labeled and then the sample was taken to the laboratory for analysis. The procedure for analyzing the sediment grains for sand and gravel fractions used the wet sieving method, for the sludge fraction was analyzed using the pipette method. The results from the wet sieving method and the pipette method were combined and the mean size (Mz) was obtained. Measurement data were analyzed using linear regression analysis, then correlation and regression analysis to determine the form of the relationship and the strength of the relationship between two or more variables. Sea turtles will lay eggs, namely the mean size ranges from 1.13-1.8 Ø. The coefficient of determination (R2) = 0.53 and the correlation coefficient r = 0.73. This means that the coefficient of determination shows the average diameter (mean size) affects 53% of the number of turtle eggs, while the other 47% is influenced by other factors, for example vegetation around the coast..

Abstract

Sumatera is one of the largest mangrove areas in Indonesia. One of the mangrove plants that have the potential as a drug and has been used traditionally is Xylocarpus granatum. This study was conducted to determine the influence of methanol extract from leaf X. granatum in inhibiting the growth of Staphylococcus epidermidis. Extraction of leaf X. granatum is done by the maceration method using methanol solvent. Test resistance of methanol extracts from the leaves of X. granatum is performed by a method of diffusion discs. Measurement of antibacterial activity is carried out with several treatments i.e. the negative control (aquadest), positive control (Chloramphenicol), and several different extract concentrations of 25ppm, 50ppm, 75ppm, and 100ppm. The value of the antibacterial activity is then analyzed further using ANOVA and the Dunn test. The results showed that the leaves extract X. granatum extracted using a methanol solvent contained active phytochemicals compounds such as steroids, saponins, tannins, and phenols. The test results of each extract concentration showed a significant influence on the slow growth of S. epidermidis, characterized by the formation of a clear zone around the disc. The highest antibacterial activity is shown at a concentration of 25ppm with an antimicrobial index value of 3,55 which is categorized as a strong antibacterial response.
