Abstract

Urinary Tract Infection (UTI) is a nosocomial infection with several occurrences around 39-60 % in Indonesia. Antibiotics are the main therapy for UTIs. The use of poor quality antibiotics can cause irrational antibiotics therapy which leads to the risk of resistance. This research aims to recognize the patterns of antibiotics use and determine the percentage of the appropriate use of antibiotics. This research is an observational type of research with a cross-sectional design. The data were obtained retrospectively from July to September 2021 using 53 medical records of UTI hospitalized patients. The obtained data were analyzed descriptively and quantitatively using the Gyssens method. The result shows the characteristics of UTI patients are dominated by males (54,72%) and occurred in toddlers at age of 0 -5 years (20,75%) and the elderly at age 56- 65 years (15,09%). The antibiotics used in this research were dominated by ceftriaxone (37,50%). Of 53 patients using 80 antibiotics, the percentage of use accuracy of antibiotics in UTI patients in RSUD Provinsi NTB (category 0) is 23,75%. The inappropriate use of antibiotics is 76,25% was found in various categories, namely category VI medical record data incomplete (32,50%), IVA where there were more effective antibiotics (10%), IVC there were cheaper antibiotics (1,25%), IIIA too long duration of antibiotics use (8,75%), IIIB too short duration of antibiotics use (7,50%), IIA improper dosage of antibiotics (11,25%), and IIB improper giving interval (5%). Therefore, it can be concluded that there is still irrational use of antibiotics, especially improper dosage category.

Abstract

Mangrove forests have very important ecological functions for coastal areas as carbon stores so this study aims to determine the potential carbon content of mangrove forests. The implementation of this research is in the coastal area of ​​West Lombok Regency, West Nusa Tenggara Province. Two locations were found, namely Sekotong Beach and Cemara Beach. This research method uses a survey method. Data were analyzed by IPCC analysis method. The results showed that at Cemara Beach the highest carbon content was produced in the mangrove species Avecennia lanata, with the total carbon content and carbon absorption being 7,456 tons C/ha and 27,364 tons CO2/ha. while at Sekotong Beach the carbon content is found in the Avecennia lanata species, with a total carbon content of 2,847.6 tons C/ha and carbon sequestration of 10,067.54 tons CO2/ha. The difference in potential carbon content on the two beaches in West Lombok district is due to because the soil conditions are different but the carbon content is still good enough for the potential carbon content in the coastal mangrove ecosystem area of ​​West Lombok Regency, West Nusa Tenggara.

Abstract

Bats (Ordo Chiroptera) are one of the animals that have an important role in the sustainability of the ecosystem such as pollinators, seed dispersers, pest control and guano producers. In addition to their important role, bats are also animals (hosts) for several types of ectoparasites. Ectoparasites are parasitic organisms that live on the surface of the host's body. Generally, suck blood and live on the host’s hair, feathers, or skin. The research was conducted in Buwun Cave Prabu Village, Pujut District, Central Lombok Regency West Nusatenggara. Data collection on ectoparasites in bats was done manually with tweezers and a comb. Furthermore, samples of ectoparasites were identified based on sources of morphological evidence and referred to various references. The results showed that there were 3 species of bats identified, each consisting of 7 species of Eonycteris spelaea, 6 species of Rhinolopus simplex, and 3 Hipposideros diadema. Based on the results of the examination of the three bat species, there were 47 individual ectoparasites, which were identified in 3 species of ectoparasites, namely Cyclopodia horsfieldii, Amblyomma sp, and Meristapsis sp.

Abstract

This study is an experimental study aimed at clarifying the characteristics of the solvent in the extraction of lycopene in tomato (Solanum lycopersicum) as a candidate photosensitizer for dye-sensitized solar cells (DSSC). The performance of DSSC  depends on the type of dye commonly used as a sensitizer. Tomatoes contain an lycopene. Yields of lycopene extract in tomatoes were characterized by FTIR and UV-Vis spectrophotometers. The extraction methods used in this study are the maceration method and liquid-liquid extraction. The procedure of this study was carried out in two main stages,  the extraction stage and the characterization stage. The first step was the extraction of lycopene from tomatoes using the maceration and liquid-liquid extraction methods. The maceration process compared the use of acetone and ethyl acetate as solvents. This extraction step produced  6.514 g (acetone) and 5.6702 g (ethyl acetate) lycopene extracts. The second step is to identify the functional groups of the compound formed using an FTIR spectrophotometer and use a UV-Vis spectrophotometer to determine the absorbance and maximum wavelength value of the lycopene and  M-lycopene complex. The results of the FTIR spectrophotometer test showed that using acetone as the solvent produced wavenumbers similar to lycopene compared to ethyl acetate.  UV-Vis spectrophotometer test results show the maximum wavelengths of the lycopene extract using acetone as the solvent were 447 nm, and 294 nm when ethyl acetate was used as the solvent. The Eg results revealed that the Eg values ​​for the acetone and ethyl acetate extracts were 4.52 eV and 2.68 eV. Based on the results of property analysis of the two solvents used, acetone was more suitable than ethyl acetate for the extraction of tomato lycopene used as a DSSC sensitizer.

Abstract

This study aimed to isolate endophytic bacteria from the roots of the gamal plant and to test its ability to solubilize anorganic phosphate dan to produce IAA (indol acetic acid). The steps in this study were the isolation of endophytic bacteria from the roots of the gamal plant taken from Woja District, Dompu Regency, the IAA test, and the phosphate solubility test using the colorimetric method. And then carried out the characterization of cells, colonies and biochemical properties of isolates. In this study, 6 isolates of endophytic bacteria from the roots of gamal plants were obtained which can dissolve phosphate, of which two isolates, namely ATG1 and ATG4 with phosphate solubility indices ranging from 3 and 4. These two isolates were also capable of producing IAA, with concentrations 16.48 and 17.72 ppm, respectively. Most of the isolates were Gram positive bacteria and were in the form of bacilli. The endophytic isolates obtained above are isolates that have the potential to be candidates for components of the biofertilizer formulation consortium in the future.

Abstract

The presence of molds in the environment around us can be beneficial or detrimental. Mold can be found in various places, including soil, air, plants, animals, water, and on material surfaces. One of the roles of mold is as a bio-degradator and biodeterioration agent on materials that are still used, so that it will cause harm to humans. This study aims to isolate and characterize the types of molds that exist on the surface of existing materials in the biology laboratory environment of Diponegoro University with the contact plate method. The method used is to attach a contact plate containing PDA to various materials such as tables, chairs, cabinets, and so on, then observe the macroscopic and microscopic morphology. The results obtained were five genera, there are Aspergillus, Penicillium, Eurotium, Rhizopus, and Absidia.

Abstract

The University of Mataram is coordinating the ARISA Corn (Applied Research and Innovation System in Agriculture) Intervention Project, which includes partners such as Bank NTB Syariah, PT. Syngenta, the Department of Agriculture, Retailer of Subsidized Fertilizers, and buyers of produce have exceeded their target of increasing 30% in revenue. The purpose of this study consisted of a general objective, namely to analyze the sustainability of the ARISA partnership project in the village of Gumantar, Kayangan District, North Lombok Regency and a specific purpose to analyze the sustainability of the partnership of corn farmers who carried out the ARISA project in the village of Kayangan District, North Lombok Regency. This study uses descriptive methods and data collection techniques with survey techniques. The sampling technique used was purposive sampling (deliberately) with the consideration that only 1 of these villages participated in the ARISA project at the beginning of the project. The technique of determining respondents using proportional sampling was determined by 15 respondents because only the corn farmers participated in the ARISA project from the beginning to the end of the project. The data analysis used is qualitative descriptive analysis. The results show that the sustainability of the partnership in the ARISA project is still ongoing even though the program has ended in 2018. The partnership between farmers and Unram does not continue in terms of the application of technology. The partnership with Bank NTB Syariah through the application of people's business credit applications and purchasing inputs according to recommendations with new suppliers is still ongoing. Field agricultural extension staff manage and coordinate fertilizer distribution with RDKK and merchants. The collaboration with yield buyers continues with new purchasers.
