Abstract

The province of North Kalimantan has a direct boundary with the eastern part of Malaysia, including the Nunukan Regency with the Sabah Region. Nunukan Regency has a number of attractive tourism places for tourists to visit, but they are still minimal in the availability of supporting infrastructure, so this research was conducted to obtain a model to support tourism infrastructure. The methodology used in this research is descriptive qualitative, by obtaining data from questionnaires and interviews with respondents from government agencies, travel business actors, to communities around tourist attractions. The object of this research is a tourist spot in Nunukan Regency, then an analysis is carried out using Interpretive Structural Modeling (ISM). The result of this research is that a model is obtained that provides the key variables that place the variable in the top position in the model. The ISM model obtained places the availability of the types of facilities that have been provided for a place to stay for visitors. This is not without reason because from interviews it was found that tourists want a place to stay overnight to be able to enjoy the natural atmosphere with their family. From the research it was also found that infrastructure remains a priority in supporting tourism objects.

Abstract

Bleaching Earth is another term used for a type of clay or clay that has a montmorillonite structure. Activation by means of physics, namely heating, can remove dirt and moisture content in the bleaching soil particles. This study aims to reactivate Spent Bleaching Earth (SBE) so that it does not become waste in the surrounding environment. As well as knowing the results of the characteristics of Reactivated Bleaching Earth (RBE) obtained. The reactivation process consists of 2 stages, namely extraction on SBE with n-hexane and activation using a furnace. The method used was maceration extraction with extraction times of 60, 90, 120, 150, 180 and 210 minutes. And the activation temperature is 500, 550, 600, 650, 700 and 750 ˚C. This research gives the result that thermal activation using the furnace can reactivate SBE so that it can match the existing Bleaching Earth characteristics. The best conditions for RBE based on the National Standardization Agency (BSN) in this study were the extraction time of 120 minutes and an activation temperature of 550 oC with a water content value of 0.1625%, real density 2.2970 gr/mL, pH 7.1, and yield.

Abstract

The Cethol fish was used as a dietary raw material of chips fish by local people in Magelang. The population of the fish was decreased and impacted to fish chips production. The Cethol fish farming could be the one of solution to maintain the stock of this fish as dietary raw material. Nevertheless, the taxonomic status of Cethol fish as the primary information of in Magelang still unclear. Taxonomic status is of organisms is useful to inform biology, reproduction and traits of candidate species will be farmed. The aim of research is revealing the taxonomic status of Cethol fish in Magelang using common barcoding marker Cytochrome Oxidase I (COI) from mitochondrial DNA. The COI gene sequences of Cethol fish from Magelang and other sequence samples from NCBI were used to construct the phylogenetic tree and haplotype network approach to reveal the similarity and clustered of the fish sequence samples. The maximum likelihood and minimum evolution were considered as construction tree method by Kimura 2 parameter statistic model and 1000 bootstrap value. The Median joining statistic model was generated to reveal grouping form and substitution rate of each samples. The phylogenetic tree was constructed from COI gene of Cethol fishes from Magelang are grouped in the same clade and monophyletic with the Poecilia reticulata COI gene from South America as the origin of the fish species. Meanwhile, the P.reticulata from Bengkulu, Sumatera and Java were clearly separated with the samples from Magelang but still in haplogroup with the South America sequence samples. Those result are strengthen the previously notion that the Cethol fish in Magelang is a group species of P.reticulata from South America.

Abstract

Leachate can be formed from the percolation of water that passes through the garbage. The high content of organik and metallic substances in leachate can cause environmental damage, so it must be treated first before being discharged into the environment. This study aims to determine the effectiveness of ozonation in neutralizing pH and reducing the levels of TSS, BOD, COD in the leachate of the Griyo Mulyo landfill using the AOPs method based on ozonation. Studies on ozonation in leachate treatment have been carried out by varying the ozonation time (15, 30, 45, and 60 minutes). Parameters that have been observed are pH, TSS, BOD, COD. The results showed that the best ozonation time for leachate pH was at 15 minutes with a value of 7, the best ozonation time for leachate TSS was at 15 minutes with a value of 56 mg/L. The best ozonation time for BOD and COD was at 45 minutes with values ​​of 511 mg/L and 1260 mg/L, respectively.  The best percentage of removal efficiency for TSS, BOD and COD reached 67%; 84.1%; and 88.41%.
