Abstract

The research used 51 tissue samples taken from 51 individual Green Turtles in Pulau Panjang, EastKalimantan. The isolation of mtDNA was achieved by adding Proteinase K into the samples prior to the utilization ofthe PCR (Polimerase Chain Reaction) technique. The MEGA 3.1 computer program was employed to read the DNAsequences obtained through the PCR technique.Seven different haplotypes were identified from the analyzed samples. The haplotypes are: A3 (N=7; 13.73%),A4 (N=1; 1.96%), A6 (N=2; 3.92%), C3 (N=5; 9.80%), C5 (N=6; 11.76%), C14 (N=5; 9.80%) dan D2 (N=25;49.02%). Tag findings clearly demonstrated that the Green Turtles, which feed on the seagrass beds of Pulau Panjang,originated in different nesting sites, including Sabah and Trengganu in Malaysia, Sangalaki and Derawan inIndonesia, and Phillipine. The MSA (Mixed Stock Analysis) showed that the Green Turtles population in PulauPanjang was composed of several management units (nesting sites), which were Berau (47%), Sulu Sea (34%) andMicronesia (6%).

Abstract

The coastal zone of South Buton Regency consists of unique ecosystems and abundant natural resources, but facing problems, mainly in terms of conflict between economic needs and ecological aspects. This study aims to set up scenarios for sustainable coastal zone management (SCZM) in South Buton Regency that are synergistic and benefit all stakeholders, without disregarding the principals of ecological conservation. Data were collected by interviews and field observations and were analyzed using prospective analysis method. Comprehensive analyisis were performed encompassing the effects and interactions of key components of the successfulness of the SCZM in South Buton based on the stakeholders desires. Three environmental management scenarios were assessed, namely: the conservative-pessimistic scenario, in which refinements for the key components are at minimum levels, the moderate-optimistic scenario, in which refinements for the key components are about 50%, and the progressive-optimistic scenario, in which all the key components are addressed for refinements. Results of the prospective analysis show that the moderate-optimistic scenario was the most appropriate scheme to be implemented for the sustainable coastal zone management in South Buton Regency, follows by progressive-optimistic and conservative-pessimistic scenarios, respectively.

Abstract

The utilization of groundwater unwise leads to problems for the life of sentient beings. The majority of environmental damage, mainly by groundwater utilization, is done or caused by human activities. The land subsidence, drought, seawater intrusion are some examples of damage caused by groundwater utilization unwise. This research aims to estimate land subsidence in southern Bali and analyze groundwater level reduction with land subsidence. The PS-InSAR technique to monitor land subsidence has been carried out in several regions in Indonesia and other countries. In this study, 38 images of Sentinel-1 taken from February 2015 to December 2018 are used to analyze the PS-InSAR technique. Land subsidence is found in Denpasar Utara district and Kerobokan district with deformation in -8 mm to -19 mm and velocity up to -5 mm/year. The utilization of groundwater causing land subsidence in Southern Bali is no significant relationship with coefficient correlation 0,16 and influenced only 2,7%. Limited groundwater data also influences the correlation between groundwater utilization and the occurrence of land subsidence. Keywords: Land Subsidence; Sentinel-1A; PS-InSAR; Southern Bali.

Abstract

Vegetable cultivation is livelihoods for side Lake Batur communities, Kintamani, Bangli. Hilly natural conditions with a soil texture influenced by the eruption of Mount Batur, 900 m above sea level, and 900-3500 mm high rainfall, causing this region is very suitable for the cultivation of various vegetables, including shallot. One effort to meet the high demand for shallots is that efforts are made to improve cultivation techniques, including fertilizing to improve yields. In modern agriculture, the use of fertilizer is absolutely essential to trigger the level of crop production. The aims is to analyze the combination effect of using of inorganic fertilizer (ZA fertilizer) and organic fertilizer (compost fertilizer) on shallot vegetable cultivation systems on the content of pollutants, N nutrients and onion crop yields on the shores of Lake Batur, Kintamani District, Bangli Regency. The study using RBD with two factors where factor I: provision of organic fertilizer is leaf compost made aerobically (O), consisted of 3 levels, namely: O0 = 0*, O1 = 5* and O2 = 10*and factor II: the application of inorganic fertilizer namely ZA (S) fertilizer, consisted of 3 levels, namely: S0 = 0**, S1 = 50** and S2 = 100**, each repeated 3 times. The parameters observed were the growth and yield of shallots as well as the content of Pb, Zn, Cu and N nutrients in the soil. The nutrient content (N) in the soil, when using chemical fertilizer ZA and compost organic is not significantly different, as well as the results of onion plants, while the content of Pb, Zn and Cu on the use of chemical fertilizer ZA and organic compost, very real different. The highest soil Pb content in S2O1 treatment is 30.07***, the highest soil Zn content in the S2O1 treatment was 28.24***, and the highest soil Cu content in the S1O2 treatment is 17.22***. *= tons/ha **= kg/ha ***= mg/kg Keywords: compost; contents Pb; Zn; Cu of soil; shallot; ZA.
