Abstract

Research about coastal forest vegetation in Sabutung island has been conducted.The aim of this research was to make an inventory of native species, introduced speciesand invasive spesies of plant in Sabutungisland. Sampling activities conducted withpurposive sampling method.Data collected with noted the plant species that foundduring exploring the island. All sample are photographed. Unidentified sample werecollected and identified in Marine and Environmental laboratory, Department ofBiology, Faculty of Mathematics and Natural Sciences, Hasanuddin University.Identification of the sample conducted based on: An Annotated Check-List of TheVascular Plants of The South China Sea and Its Shores by Turner et al. (2000) and Mangrove Guidebook for Southeast Asia by Wim Giesen et al. (2007)for coastal forestspecies; Tropical flowering plants: a guide to identification and cultivation by KirstenAlbrecht Llamas (2003) for introduced species andNonnative Invasive Plants of PacificCoast Forest. A Field Guide for Identification oleh Gray et al. (2011) and Guide to TheNaturalized and Invasive Plants of Southeast Asia by Arne Witt (2017) for invasivespecies. Data were analysed descriptively and displayed in tabular form. Antropogenicimpact i.e: land conversion and increased population were also discussed. From theresults of the study were recorded as many as 221 species of plants in Sabutung Island.Mostly dominated by ornamental plants and cultivated (introduced) plants with 131species of 46 tribes followed by native species with 67 species from 34 tribes. Invasivespecies were recorded with at least 19 species from 8 tribes. Nonetheless, invasivespecies are widespread and dominate space in almost all parts of the island. Most of thecoastal forest on Sabutung Island has been lost due to land conversion to settlementsand garden/plantation.

Abstract

Pulmonary tuberculosis caused by Mycobacterium tuberculosis become ahealth problem in Indonesia. The chronic nature of this disease is further exacerbated ifit is accompanied by fungal infection such as Candida albicans and Aspergillus sp.,which is usually remains undiagnosed and thus untreated. Culture techniques can beused to identify Candida sp and Aspergillus sp from bronchoscopy. Fungal culturemedia in laboratory containing high carbohydrate source, nitrogen source are requiredfor the growth. This nutrient can be found in bran that contains high carbohydrates,proteins, fats, vitamins, and crude fiber. So that bran can be used as raw material for alternative fungal growth media. The purpose of this study was to increase bran as amedium for the growth of Candida sp and Aspergillus sp isolated from bronchoscopy ofpulmonary TB patients. This study included bran collection, preparation of bran media,inoculation bronchoscopy on bran media, observation of fungal growth. Colonies ofCandida sp and Aspergillus sp were confirmed microscopically. The results showed thatCandida sp and Aspergillus sp grew on both media, Bekatul Dextrose Agar and PotatoDextrose Agar. The conclusion of this study is that bran can be used as a medium forfungal growth. Bran media can be used as an alternative media to replace syntheticmedia to grow Candida sp and Aspergillus sp isolated from bronchial rinses.

Abstract

The high prevalence of typhoid fever in developing countries, includingIndonesia has prompted the exploration of various serologic tests and antigen detectionmethod to obtain an early and accurate diagnosis of patients with typhoid fever.Although typhoid fever is confirmed by culture of Salmonella enterica serotype Typhi,there is still an urgent need for the rapid, simple serological tests and evaluation ofeffective and appropriate diagnostics for typhoid fever. In this study, we evaluated and compared the sensitivity and specifity of ELISA and Passive Bacterial Agglutination(PBA) as an agglutination-based serological test to LPS antigen of Salmonella Typhiand the effectiveness of local antigen in detecting the production of specific antibody(IgM) to patient with typhoid fever. We collected serum sample of 50 suspected typhoidfever from DR. Wahidin Sudirohusodo General Hospital, Daya General Hospital, GowaGeneral Hospital and Kassi-Kassi Public Health Center in Makassar, South of Sulawesi.They were grouped based on sex, duration of fever, and age. Serum antibody titer weremeasured by ELISA and PBA. Data were analiyzed satistically by using cross tabulationand chi-square (CI = 95%). The Result of this study showed that PBA technique has thelevel of sensitivity and specifity respectively 100% and 92 %, while ELISA was 84% and28%. It suggested that PBA has a greater level of sensitivity and specifity than ELISA.We also showed that LPS antigen that we obtained from local isolate of SalmonellaTyphi, can be used as a standard antigen in diagnosing typhoid fever.

Abstract

This study aims to develop a dynamic system model that describes the relationship ofwater, socio-economic, and water resources (lake size) sub-systems in Situ Binong. In addition,this study also aims to make predictions of water resources conditions (lake size) Situ Binong forthe next 5 years. The model is prepared using a dynamic system approach. The Situ Binong waterflow model is available water resources consisting of 3 sub-systems namely natural water flowsub-systems, socio-economic, and water resources Situ Binong. The result of the research showsthat the requirement of Situ Binong water resources every year is increasing so that the volume ofSitu Binong is decreasing. In addition, the volume of water resources Situ Binong influenced bysupply and demand. Supply comes from domestic waste and natural water flow such asprecipitation, infiltration and surface flow. While demand comes from WTP intake, irrigation, andevaporation.

Abstract

This study aims to find out the comparison of the growth on wick and NFTdesigns and to know the hydroponic design more effective between the two systems tooptimize the growth of kangkung plants. The method used is quantitative experiment witht-Test test data analysis: Paired Two Sample For Means (two paired samples). The studywas conducted for two weeks with one week of seeding and one week of measurement.The parameters observed were number of leaves, leaf length, leaf width, and stem height.The results showed that the growth of kangkung plants in hydroponic wick design isbetter than the NFT design. The growth on wick design can be said better because in thisdesign each hydroponic place is only filled by one kangkung plant so that the absorptionof nutrient solution can occur more optimally. This study proves that there aredifferences in the growth of kangkung plants in wick and NFT design.
