Abstract

The diversity of activities along the Balangan river causes waste disposal, which contributes to an increase in pollution load in the Balangan river. The purpose of this study is to predict the water quality conditions spatially using IDW method, and to determine the relation among distance and water quality status. In the whole location, the results showed that the pollution load capacity was exceeded, the levels of BOD5, COD, Sulfide, Iron, Manganese and Phosphate were parameters that had exceeded the quality standard. The pattern of water quality decreases in the downstream area, especially at BOD5 and COD levels. While the levels of TSS, Nitrate, Nitrite, Ammoniac, Iron, Manganese, and Detergent showed a temporary pattern of decline and showed an increase again. Phosphate levels showed a temporary increase and then there was a decrease again afterwards. Based on the sampling location the distance between the starting point and end point is 12 km, the prediction of the distribution of water quality using IDW shows that at a distance of 1-6 km shows a stable water quality pattern, a distance of 7-10 has improved water quality and 11-12 has decreased water quality.

Abstract

AbstractCommunity participation is one of the keys to success in the process of developing agrotourism in an area. This study aims to analyze the level of community participation in the development of Agro-tourism in Karangsari, Blitar, East Java. Community involvement in the planning, implementation, evaluation, and USE of the results or output is a major factor in developing Karangsari Starfruit Agro-tourism. Data collection research was carried out by distributing questionnaires to respondents consisting of stakeholders and communities around the agrotourism site. The data is processed using Microsoft Excel 2013 and Rank-Spearman Correlation Analysis using IBM SPSS 20. The results of the study show that the lack of community participation in the agrotourism development process occurs because it is influenced by internal factors such as age, education, employment, income level and length of stay. In addition to the influence of these internal factors, community members are also still not involved in any agrotourism development activities. The participation of the community can be improved by conducting activities that require the surrounding community to participate.

Abstract

Danyangan is A proof traditional conservation created by local wisdom. Knowledge of bioculture provides a facts play a role in understanding the ecological processes that occur and providing an overview local efforts in protecting the environment. The village’s. Danyangan has the form of a collection of large trees marked by the presence of sacred fig trees (Ficus sp.). Moreover, the fig tree become a habitat for several species of birds. The canopy’s cover reserves water, insects, and fruits as food for birds and creates an interesting relation as a microhabitats.The location of this study was carried out in the administrative district of Malang district in Tumpang, East Java in the area of the district located in Gubugklakah, Kunci, Drigu, Poncokusomo, Puthuk, Pandansari, Jajang, and Aran-aran. Bird observation is carried out using the point count or IPA method.The study recorded 636 individuals consisting of 31 species, 21 families and 9 orders. The birds identified were dominated by Passeriformes as many as 11 families. Based on the results, shows all locations in the danyangan area dominated by detailed Swallow (Collocalia linchii). Instead, The value of bird species abundance in all study locations is included in the high category of values ranging >4.A spatial review is needed to see the extent and potential of danyangan on the western semeru slopes in an effort to conserve biodiversity, especially birds. As inthisstudy, we investigated thecomposition, diversity and Geographic Information System of birds in the Danyangan area.A spatial review is needed to see the extent and potential of danyangan on the western semeru slopes in an effort to conserve biodiversity, especially birds.

Abstract

Indonesia is committed to achieving the SDGs in 2030. One of SDGs is protect the marine ecosystem. Bandar Lampung which has a coastal area in a form of a dock for sea transportation and the anchoring of fishing boats. These area are starting to be polluted due to waste, one of which is the fuel waste of ships or fishing boats that are in the area. When the quality of sea water decreases due to pollution it will have an impact on population and diversity of marine life. If this happens the sea will be damaged and the income of fishermen will decrease. Various studies have been conducted to overcome problems caused by oil (petroleum hydrocarbons), especially research on the use of microbiology in remediating polluted environments. Therefore, this study was conducted to test P1 isolates isolated from sea water in docks around Bandar Lampung. The Measurement was carried out at The Integrated Laboratory of ITERA by observing the growth of the bacteria (population of bacteria) on selective media that had been added with diesel oil as much as 2% (v/v). This measurement was carried out on day 1, day 4 and day 7 after incunbation for population and for % TPH was measurement in the first day and the last day of incubation. The results obtained that the GT1 isolate have a good result in population and decreasing of TPH than the other isolate.

Abstract

Uwi tubers (Dioscorea alata) are widely used as biodegradable plastics materials because it contains high starch content about 75,6 – 84,3%. Biodegradable plastics can be used as a decent food wrapping. The purpose of this research is to study the process of making biodegradable plastics and analyze the effect of a adding CMC (carboxymethyl cellulose) and sorbitol plasticizers on the physicochemical properties of biodegradable plastics from uwi tuber starch with various parameters, solubility, thickness, tensile strength, elongation, modulus Young, compressive strength, biodegradability and surface morphology of functional groups. The making of plastic biodegradables is based on the melt intercalation method. Uwi tuber starch composition used was 5 grams, the combination of CMC concentration used was 0 gram; 0,20 gram; 0,30 gram; 0,40 gram. While the variations in the volume of sorbitol used are 2 ml, 3 ml, 4 ml, 5 ml. The results of this study indicate that the additon of 0 gram CMC and 2 ml of sorbitol produce tensile strength values of 7,66 MPa, the best modulus Young is 5,52 MPa. The compressive strength values is lower that is equal to 0,150 kgf, the best elongation value is at the addition of CMC 0,20 gram and sorbitol 5 ml that is equal to 39,44%. The concentration of the CMC addition and sorbitol plasticizer on biodegradable plastic affects physical properties in SEM testing with the additon of 0 gram CMC and sorbitol 2 ml, which results are denser when compared with the addition of 0,40 gram CMC and 5ml sorbitol. In the FTIR test, there are C-O alcohol/ester/carboxylic acid/eter functional groups in waves 1050-1300. Plastics with the highest concentrations of CMC and sorbitol need 7 days to be degraded.
