Abstract

The development of the Batang Integrated Industrial Estate (KITB) since 2020 has triggered large-scale land transformation that has the potential to affect environmental biophysical conditions, particularly land surface temperature (LST), vegetation density (NDVI), and built-up land cover (NDBI). This study aims to evaluate the spatial and temporal changes in these three parameters during the 2019–2024 period and to analyze the statistical relationships among these variables. The data used consist of Landsat 8 and Landsat 9 satellite imagery for the years 2019, 2021, 2023, and 2024, which were processed to derive LST using the mono-window method, NDVI through the NIR–Red band combination, and NDBI using the SWIR–NIR bands. Spatial analysis was conducted through the mapping of the distribution of each parameter, while statistical analysis included descriptive statistics, Pearson correlation, and linear regression. The results indicate that the development of KITB has produced significant thermal and ecological impacts. LST increased from approximately 23–32°C in 2019 to 28–38°C in 2024, with higher temperature concentrations observed in the industrial core area and active construction zones. NDVI experienced a decline in areas that previously consisted of moderate to dense vegetation, particularly in the southern and western parts of the industrial estate, as indicated by the shift in NDVI map colors from green to brownish-red. Meanwhile, NDBI values showed a dominant increase in 2023–2024, corresponding to the expansion of built-up areas within the industrial zone. The correlation results show a strong negative relationship between NDVI and LST (r < 0), indicating that vegetation loss contributes to the increase in surface temperature. Conversely, a positive relationship was identified between NDBI and LST, suggesting that the expansion of built-up land cover contributes to surface warming. Overall, these findings confirm that the development of KITB has triggered significant increases in land surface temperature and vegetation degradation, highlighting the importance of green space management and thermal mitigation strategies in rapidly developing industrial areas.

Abstract

The Wanadipa Special Purpose Forest Area (KHDTK) of Diponegoro University in Semarang provides an important refuge for wildlife amid ongoing habitat degradation in Java. This study assessed bird species, abundance, and conservation status in the educational research block and agroforestry rehabilitation zone. Surveys conducted in February 2026 using point count method at five stations recorded 133 encounters of 26 species. The most abundant were the cave swiftlet (25 individuals) and sooty-headed bulbul (17 individuals). Ecological analysis indicated a stable secondary forest ecosystem, with moderate Shannon-Wiener Diversity Index values (H’ = 2.48–2.51), low Simpson Dominance Index (D = 0.11–0.12), and high Evenness Index (E = 0.83–0.87). Five protected species were documented, including the endangered Javan hawk-eagle, alongside the crested serpent-eagle, Javan banded pitta, oriental honey-buzzard, and racquet-tailed treepie. The KHDTK Wanadipa harbors five IUCN and CITES-listed species, comparable to larger Mt. Ungaran (six species) and the Semarang urban forest (six species). These findings highlight the effectiveness of Wanadipa KHDTK as an ecological buffer supporting rare bird conservation in Semarang, Central Java.

Abstract

Spirulina is a microalgae rich in protein, fat, carbohydrates, minerals, chlorophyll a, phycocyanin, beta-carotene, linoleic acid, and vitamins. Nanochitosan, a polymer derived from chitin, contains amine and carboxylate groups. Both additives enhance digestion, absorption, and duodenal structure in broilers. This study analyzed the effect of combining spirulina flour and liquid nanochitosan on broiler duodenal histology. A 3 × 2 factorial completely randomized design (CRD) with four replicates was used. The first factor was spirulina flour (0; 3; 6%), and the second was liquid nanochitosan (0 & 5%). Measured variables included duodenal weight, length, villus height, epithelial thickness, muscular layer thickness, and lumen diameter. Data were analyzed using ANOVA at a 5% significance level. Results showed spirulina alone affected duodenal lumen diameter (P <0.05), while nanochitosan alone had no effect on duodenal length, villus height, epithelial thickness, muscular thickness, or lumen diameter (P >0.05). The combination significantly increased duodenal weight (P <0.05) but did not affect other variables. In conclusion, spirulina and nanochitosan improve duodenal weight but do not alter duodenal length, duodenal lumen diameter, villus height, or layer thicknesses.

Abstract

Klanceng honey is a type of honey produced by stingless bees. The characteristics of klanceng honey are a liquid texture and a more sour or bitter taste. The content of honey is influenced by the honey's food source, which can be seen from the pollen contained in the honey. Identified pollen can be used to indicate the characteristics of the plants that serve as bee food sources. The purpose of this study was to determine the diversity of pollen sources in klanceng honey from Penggung Village, Boyolali Regency; Kebonrejo Village, Magelang Regency; Ceper Village, and Ngemplak Village, Klaten Regency, which can be used to identify plants that serve as bee food sources and be used to label honey based on its food source. The sampling method used exploratory sampling with purposive sampling. The pollen analysis method used acetolysis. Data analysis used descriptive analysis. The results of melisopalinology showed that there were 26 plant pollen families contained in the four klanceng honeys, with coconut (Cocos nucifera) pollen being the most dominant. Klanceng honey from Ceper and Kebonrejo villages is monofloral, while honey from Penggung village is bifloral, and honey from Ngemplak village is multifloral. The conclusion of this study is that the plant diversity of klanceng bees' food sources is diverse.
