Abstract

The purpose of this study was to determine the influence of leadership style and organizational culture on employee performance with job satisfaction as an intervening variable at the Cilegon City Food and Agriculture Security Agency. The population in this study were all employees of the Cilegon City Food and Agriculture Service. The sampling technique in this study was the saturated sampling technique, where the entire population was used as a research sample (census sample), so the sample size used in this study was 100 respondents. The research will be tested using the Partial Least Squares (PLS) analysis tool. PLS can also be used to explain whether there is a relationship between latent variables and to analyze constructs formed with reflective and formative indicators. Based on the research results, the following conclusions can be drawn: 1) Leadership style has a positive and significant effect on employee job satisfaction; 2) Work culture has a positive and significant effect on employee job satisfaction; 3) Leadership style has a positive and significant effect on employee job performance; 4) Work culture has a positive and significant effect on employee job satisfaction; 5) Job satisfaction has a positive and significant effect on employee performance; and 6) Job satisfaction can mediate between the variables of leadership style and work culture on employee performance variables.

Abstract

This study aims to analyze the impact of environmental biogeography on point mutations in Kosta and Lakor goat breeds as local Indonesian germplasm using the GDF9 Exon 1 gene sequence. A total 43 folicle samples of Kosta and Lakor goats which collected in Serang regency and Lakor island were analyzed. To isolate the total genome of the samples, the tissue isolation method was used. The polymerase chain reaction (PCR) method was used for amplification of the exon-1 region of the GDF9 gene with two pairs of primers. Analysis of genetic variation and single nucleotide polymorphisms (SNP) using MEGA software version X. Multiple alignment results showed that there are 2 nucleotides that have mutations, but not encode different amino acids. This results indicates that the mutation has association with litter size of two breeds. This finding shows that Lakor goats have polymorphism i.e SNP g.54C>T which is significantly associated with litter size. The analysis of GDF9 gene showed that all samples from the Two local Indonesian goat breeds (Kosta and Lakor) are  monomorphic. But, although both are monomorphic, geographical isolation still contributes to genetic drift within and between populations.

Abstract

Indonesia is a country with very high biodiversity and is known as Mega Biodiversity. In Indonesia found about 450 species of Anura representing about 11% of all species in the world, and 28 species ofwhich 28 live in West Java.  Anura animals have a pattern of calling behavior that is essential for mating: males produce call-up behavior that attracts females and, in some species, represents the extent of their territory. Research on frogs and toads is considered necessary considering the absence of more detailed data on the bioacoustics of these frogs, especially in the West Java area, so that variations and patterns of anura sounds are known in the Telaga Warna Nature Reserve and Nature Park (CA-TWA) area and can make scientific contributions in information on variations and sound patterns owned by anura animals in terms of anura conservation in Indonesia.  This research was conducted from month March-December 2018, located in Telaga Warna Nature Reserve and Nature Park, Bogor, West Java.  Call the recording every 6:00 p.m. to 11:00 p.m. each night during the sampling period.  The number of anura species in the villa and swamp areas is more abundant than the lake area, and the presence of Pearl maroon frogs (nyctixalus margaritifer) found in the villa and lake areas, while the Bufo melanotictus type that likes to live in the lake area. It can be seen that the villa and swamp areas are still maintained vegetation by looking at the medium density of the canopy. Steeper slope conditions help the flow of nutrients from the soil due to the erosion process and settle in flat to gentle areas. The density of the canopy in the area helps maintain the surface temperature of the land with a stable land surface temperature ranging from 15 – 21 0C.

Abstract

Water quality in cultivating marine organisms is a very important part to pay attention to. Prevention of pollution in marine waters needs to be done by recognizing changes in physical, chemical and biological parameters in these waters from normal conditions. To find out these changes, it is necessary to carry out measurements which include parameters that determine the quality of a liquid and carry them out periodically. The measurement parameters measured include pH, Dissolved Oxygen (DO), Electrical Conductivity (EC) and temperature. The use of technological developments, especially in the world of microcontrollers, namely the ESP32 device, makes it possible to design measurement instruments in determining the quality of sea waters to be more efficient and comprehensive. The instrument created in this research will be equipped with several sensors that will read the parameters that determine water quality. The sensors used are pH sensors, DO sensors, EC sensors and temperature sensors. This research aims to create an integrated instrument (pH, DO, ED and Temperature) with instrument performance specifications that have good accuracy and a portable design so that it is easy to use in the field. The research results show thatdevelopment of a biosensor instrument for measuring seawater quality based on the ESP32 DevKit V1 can work well and can display temperature, degree of acidity (pH), DO and EC parameters on the LCD screen according to actual conditions with a difference range in percent between 0.2% - 4.16 %. The accuracy level of the designed tool is classified as having a high accuracy above 95%

Abstract

Pollution in Jakarta Bay associated with terrestrial run-off and eutrophication. Bivalves have been recognized as aquatic organisms that play the most dominant role in aquatic ecosystems. Pb is an element that in many cases causes health problems in the liver, kidneys, hematopoietic system and nervous system. This study aims to analyze the bioaccumulation of Pb in the gills of P. viridis in Jakarta Bay, and its histological changes. Bioaccumulation analysis using the AAS and histology changes using transmission electron microscopy (TEM) methods. The results of AAS, showed that the value of Pb concentration in gill tissue at the two seasons did not show a noticeable difference. Pb concentrations in gills were lower at 1, 4, and 5 than at 2 and 3 stations. The results of ultrastructure analysis as an impact of Pb accumulation showed that thickening of the nucleus membrane, and a decrease in the number of microvilli. The thickening of the nucleus membrane, and the decrease in the number of microvilli are cellular responses to the entry of the Pb heavy metal into the cell. Besides, the results of this study showed inflammation, a decrease in the number of mitochondria, as well as causing cristae to be empty.

Abstract

The Black Soldier Fly (BSF) (Hermetia illucens Linnaeus, 1758) has long been recognized as an organism used in organic waste processing through bioconversion methods. H. illucens is known to digest organic materials into nutrient sources utilized for biomass formation with the assistance of decomposer microbiota. However, research on the structure and composition of its microbiota remains limited. This study aims to identify microbiota and their structural composition in both the larval and adult fly phases, based on organic waste feeding in tropical regions. Additionally, it seeks to provide recommendations for relevant stakeholders in identifying potential environmental bioremediation agents. The research method employed is a survey study with quantitative sample analysis. The amplification process in this study uses primers from the (V1-V9) regions of the 16S rRNA gene. Data analysis is conducted using the QIIME (Quantitative Insights into Microbial Ecology) method, utilizing high-throughput sequencing community data with QIIME2 software version 3.5.3. Microbiota from the families Lactobacillaceae and Morganellaceae have been identified as dominant in larvae, while Staphylococcaceae and Bacillaceae dominate in adult flies. Morganella morganii, Herbaspirillum piri, Dysgonomonas capnocytophagoides, and Clostridium intestinale are potential candidates for organic waste bioremediation from BSF larvae. Meanwhile, Sphingobacterium wenxiniae, Lachnoclostridium phytofermentans, Mammaliicoccus sciuri, and Corticicoccus populi are bioremediation candidates from BSF flies. The genera Enterococcus, Morganella, and Dysgonomonas are found in both temperate and tropical climate regions. However, Providencia, Klebsiella, Scrofimicrobium, and Actinomyces, which are found in the gut of BSF larvae in temperate regions, are absent in BSF larvae from tropical Indonesia. Conversely, Limosilactobacillus, Entomomonas, Lachnoclostridium, and Clostridium are not found in the gut of BSF larvae in temperate regions.

Abstract

The importance of developing science literacy in elementary schools to increase the student’s problem solving abilities. By strenghtening science literacy, students are better to understand complex concepts an apply logical reasoning to fine efective solutions. This research made is to analyze the influence of PBL on science literacy skills, creative thingking skills on science literacy competence, and the interaction between PBL, creative thingking skills dan science literacy. This research involved fourth grade students from SDN 137 Cijerokaso Kota Bandung, divided into a experimental and control group. Using a quasi-experimental research design, an instrument to get a creativity is a open-ended task while science literacy was measured using mulyiple choice test. Two-way ANOVA results showed that PBL alone did not significantly affect science literacy skills (sig = 0.726). However, creative thingking skills had a significant impact (sig = 0.008), and there was a significant interaction effect between PBL and creative thingking skills on science literacy (sig = 0.021). These findings indicate that while PBL by itself may not directly enhance science literacy, its combination with student creative thingking skills contributes meaningfully to improving students’ science literacy skills.

Abstract

The background to this research is the lack of maximum critical thinking skills of students in science learning in elementary schools. This research aims to analyze the increase in students' critical thinking skills and learning effectiveness after using the multiliteracy learning model. The method used is quasi-experimental with Nonequivalent Control Group Design. This research used a sample of 36 grade 5 students at SDN 254 Griya Bumi Antapani as an experimental class using a simple random sampling technique. The data collected to answer the research questions came from the pre-test and post-test which were carried out twice each at the 1st and 2nd meetings between the control class and the experimental class. The tests carried out are in the form of essay questions that have been validated by experts and are used to measure student learning outcomes that lead to critical thinking. Meanwhile, non-tests in the form of observations are useful for observing the effectiveness of student learning during the learning process. The treatment given is a multiliteracy learning model for the experimental class with adjusted syntax. Meanwhile, the control class uses a conventional model (lecture method). The results of this research show that the application of the multiliteracy learning model in science lessons after being tested using the t-test significance test shows that there are significant differences in 5 aspects of critical thinking for elementary school students as evidenced by the data from the control and experimental classes at meeting 1 which received an average score - 4.180 and at meeting 2 they got an average score of -6.814. This shows that the multiliteracy learning model is effective and significant in improving students' critical thinking skills in achieving success in the learning process and student learning outcomes in elementary schools.
