Abstract

The dug well water quality in community settlements needs assessment to ensure its quality. The water has to meet the required physical, chemical, and bacteriological standards. This initial research aimed to determine the dug well water quality in Kampung Ujung, Komodo District, Labuan Bajo City, WestManggarai Regency in September 2019. The research method was used survey and laboratory. The two dug well was taken used a purposive sampling technique. The test parameters include temperature, turbidity, pH, smell, Total Suspended Solid (TSS), sulfate, Total Dissolved Solid (TDS), nitrate, nitrite, Total Hardness, Dissolved Oxygen (DO), nitrogen ammonia, total coliforms, and Escherichia coli. The analysis physically, chemically, and biologically of two dug well water samples were had done examined. The result showed that the parameters of TDS, nitrate, nitrite, E. coli, and DO exceed the Class I Water Quality Standard. The research concluded that the quality of both dug well water in the Kampung Ujung Labuan Bajo area was not suitable for use as material raw drinking water. Furthermore, the government should provide other water sources such as the addition of storage tanks for raw water, so that people do not entirely depend on dug well water.

Abstract

The Papuan people turn their unproductive land into fallow land. The length of the fallow period needs to be studied to identify its effect on the fertility status of the former plantation land. This study aimed to identify the fertility of the former Arfak tribal gardens based on different fallow periods. This research was conducted in Ayambori Village (two types of land, namely Active Gardens (AK) and ten-year-old fallow land (Br1)), and Bremi (three types of land, namely former cocoa plantations (Br2), primary forest (Br3), and coastal fallow land (Br4)) Manokwari Regency, West Papua Province. Soil samples were taken in each ex-garden land using a soil drill with a depth of 0-20 cm. Soil analysis was carried out at Laboratory. The elements analyzed included pH, Organic C, total N, C/N ratio, available P2O5, potential P2O5, potential K2O, Ca, Mg, K, Na, CEC, KB, Fraction, and soil texture class. The results showed that Br1, Br2, and Br3 fields showed moderate fertility status. On the other hand, AK1 and Br4 fields showed low fertility status. The research concluded that land age did not affect soil fertility status. Soil texture impacts soil fertility, where clay is better than sandy. Further research can examine the influence of microbes on soil fertility in fallow land.

Abstract

Malaria is endemic in most parts of Indonesia. Anopheles aconitus and Anopheles maculatus are examples of dominant malaria vectors in Indonesia. Plant secondary metabolites can be used as malaria vector control that is safe for the ecosystem, one of which is Durio zibethinus leaves which are thought to have active compounds so that they can be used as botanical larvicides. This study aimed to determine the potency of D. zibethinus leaf extract against An. aconitus and An. maculatus and to determine the concentration, type of extract and content of secondary metabolites of D. zibethinus leaves. Determination of LC50 and LC90 using probit analysis. Maceration and remaceration were used to produce the extract and phytochemical screening to determine the active compound of D. zibethinus. The WHO insecticide bioassay testing procedure was used for the larvicide test. Ethanol extract of D. zibethinus leaf as a larvicide for An. aconitus second and third instar and larvae of An. maculatus second and third instar had LC50 ​​respectively: 480; 520; 510; and 540 ppm and LC90 respectively: 750; 760; 760; and 810 ppm. D. zibethinus leaf aqueous extract as larvicides against larvae of An. aconitus second and third instar and larvae of An. maculatus second and third instar had LC50 values ​​respectively 14,500; 16,400; 22,100; and 23,300 ppm and LC90 respectively, 26,100; 27,200; 30,600; and 33,700 ppm. Ethanol extract of D. zibethinus leaves was more effective as a larvicide. Alkaloid, saponins and tannins were found in the leaves of D. zibethinus through phytochemical screening.
