Abstract

South Konawe District at Southeast Sulawesi Province is a producer of agriculture such as Papaya fruit ranging from 1168 quintals each year. Papaya fruit contains β-carotene which plays an important role in the formation of vitamin A in the body. This research was conducted to determine the β-carotene content of papaya fruit by using variables planting method, fruitage, and fruit condition. The mashed fruit was extracted using n-hexane: acetone: ethanol (2: 1: 1) v/v, then separated from polar and non-polar solutions. Qualitative analysis was carried out using the Carr-Price method and quantitative analysis or determination of β-carotene levels using the UV-Visible spectrophotometric method λ = 452.0 nm. The qualitative test results showed that the papaya fruit in the papaya fruit obtained by cultivation and growing wild with each variable half-ripe, ripe, and not fresh papaya identified the presence of β-carotene. The results of quantitative analysis of β-carotene levels in cultivated papaya fruit were 1.76 μL, half-ripe 1.32 μL, and cultivated young papaya 1.22 μL. In wild ripe papaya 1.75 μL, wild half-ripe papaya 1.3 μL and wild young papaya 1.21 μL. There is an effect of each test parameter starting from the parameters of planting method, fruitage, and fruit condition on β-carotene content in papaya fruit.

Abstract

Hospitals must continue to develop in order to improve the quality of hospital services. The purpose of the study was to determine the relationship between the work environment and job satisfaction of nurses at Bahteramas Hospital, Kendari City. Quantitative research method with cross sectional study approach with relative random sampling technique. Data analysis using Chi-Square test and multiple linear regression analysis. The results showed that there was a relationship between transformational leadership and nurse job satisfaction (p=0.001), structural empowerment and nurse job satisfaction (p=0.001); ideal professional practice with nurse job satisfaction (p = 0.001); innovation with nurse job satisfaction (p=0.013); and empirical quality with nurse job satisfaction (p = 0.017). The conclusion is that the determinant analysis states that there is a relationship between the work environment and job satisfaction of nurses.

Abstract

The supply of electrical energy in Tarakan City, North Kalimantan, still relies on diesel power which uses a limited number of petroleum energy sources. There is a need for research related to renewable energy sources that have the potential to become alternative energy for the people of Tarakan City. Water is an energy source that has great potential to generate electricity. The energy source that should be taken into account is micro-hydro which can be used as a Micro-hydro Power Plant (PLTMH). A survey of micro-hydro sources in Tarakan City, precisely in the Karungan area, East Mamburungan Village, has been carried out with the direct measurement method of water discharge and the relationship with the power generated. The result shows the water source has a discharge 0.00034 m3/ s, the water velocity of 0.035 m/s and generates power only up to 1.1 watts. Based on the power obtained, the water source in this place cannot be used as a source of micro-hydro energy, but has the potential as a source of pico-hydro energy.

Abstract

Knowledge of farming communities in Desa Tridana Mulya before and after household air pollution (HAP) is described in this study. Using quantitative methods, generally farmers' knowledge about air pollution in a household is still low (low category 60%; medium 3%; high 5%). One alternative to increase the knowledge of these farmers is through counselling activities on air pollution in the household. After the knowledge extension activities, the farmers were categorized as high as 70%, medium 25% and low 5%). Shows Spearman's correlation test that P-value = 0.005 is smaller than the α value = 0.01, so H0: ρs = 0 is rejected, this meaning knowledge of the farming community before and after being given counselling a significant correlation. Counselling can significantly.  increase farmers' knowledge about air pollution household (HAP).

Abstract

This study analyzed the concentrations of TSP and CO at 2 different sites in Kota Kendari. Measurement of TSP levels at the site I, Jl. MT Haryono, the highest concentration occurred in the morning (79 g/Nm3) compared to midday (51 g/Nm3) and in the afternoon (46 g/Nm3). Judging from the quality standards based on PP No. 41 of the year 1999, the concentration of TSP and CO on Jl. MT Haryono has not exceeded the quality standard. However, according to PP No. 22 of the year 2021, the CO level has reached the quality standard threshold. At site II, the TSP level at Jl. The highest Achmad Yani occurred in the morning at 63 g/Nm3 compared to midday (28 g/Nm3) and in the afternoon (35 g/Nm3) while CO levels in the morning, afternoon, and evening remained stable at 12,000 g/Nm3. Based on PP No. 41 of the year 1999, the concentrations of TSP and CO in ambient air on Jl. Ahmad Yani has not exceeded the quality standard, but if it is reviewed based on PP no. 22 of the year 2021, CO levels have exceeded the quality standard threshold. Physical factors (temperature, wind speed, and humidity) and anthropogenic factors such as motorized vehicle traffic are maybe contributions.

Abstract

Kendari bay covers an area of roughly 19.05 Km2 that boasts the mangrove ecosystem, where development around the gulf of Kendari resulted in changes in environmental conditions especially in the water quality that affected the mangrove ecosystem around the bay. The aim of this study was to analyze the oceanographic dynamics of the waters in the gulf of Kendari. The direct results include degrees of acidity (pH), temperatures, salinity and tides at 3 point measurements stations in the waters surrounding the Kendari bay mangrove ecosystem. The result is that the gulf of Kendari has a degree of acidity (pH) 6-7, the average temperature of 27°C - 29°C, a salinity of the 30-30 ppt interval, which in turn the tide of the gulf of Kendari is that the first high tide of 177 cm occurs at 2 p.m. and the second high tide of 190 cm occurs at 2 a.m. Whereas the first low tide of 74 cm occurs at 8 p.m. and the second low tide of 9 cm occurs at 8 a.m.
