Abstract

Education tourism is a sustainable activity aimed at reducing environmental impact, protecting ecosystems, promoting economic development, and improving the quality of life of local residents. Edutourism and recreation has important role in socio-economic development and environmental infrastructure. Ngesrepbalong Village is a rural area in Limbangan District, Kendal Regency, Central Java. The diversity of vegetation and the vastness of nature make this area an ideal habitat for various fauna, especially birds. Birdwatching is an edutourism activity that accordance with the potential of this village. Several areas show high potential to be utilized as birdwatching tracks. The research was conducted using the Index Point of Abundance (IPA) method, and the data were analyzed using the Shannon-Wiener Diversity Index and Simpson’s Evenness Index. Based on observations of the tracks in Ngesrepbalong Village, the bird diversity index values from highest to lowest were: Watu Ondo (3.03), Curug (2.80), Gempol (2.62), and Tea plantation (2.09), with an average value of 2.635. These results indicate a medium level of bird species diversity. Therefore, Ngesrepbalong Village has potential to be developed into an ideal destination for birdwatching and edutourism, offering natural beauty and biodiversity supported by a rich variety of vegetation.

Abstract

This study sought to assess the effects of simultaneous Gleptoferron and Toltrazuril administration on hematological parameters, health status, and growth performance in pre-weaned piglets. A total of 54 piglets aged 1 to 3 days were randomly allocated into three groups: a control group receiving a placebo injection, a group administered iron (Ferdex), and a group injected with Gleptoferron in conjunction with Toltrazuril (Forceris). Hematological markers, morbidity, mortality, and body weight growth were evaluated during a 20-day duration. The findings indicated that the administration of Gleptoferron and Toltrazuril markedly elevated red blood cell (RBC) counts, hemoglobin concentrations, and hematocrit levels relative to the iron-only group, without an increase in total white blood cell (WBC) counts, suggesting the absence of post-injection infection. Moreover, pigs administered Forceris did not develop hypochromic anemia and had a reduced incidence of diarrhea (6.7%) with no mortality, indicating enhanced gut health and excellent coccidiosis prevention. Significantly, pigs administered Forceris exhibited a weight gain of 9 kg at 20 days of age, in contrast to 7.9 kg in the iron-only cohort. The results indicate that the simultaneous use of Gleptoferron and Toltrazuril provides more advantages in avoiding anemia, improving growth, and fostering better health outcomes in pre-weaned piglets than iron supplementation alone. This efficient and pragmatic approach has significant ramifications for enhancing production in pig breeding operations

Abstract

The poultry sector in Bali has experienced substantial growth, accompanied by a notable increase in broiler chicken populations. Information on Klebsiella spp. outbreaks in Bali has not yet been studied, despite the many potential infectious diseases that may affect broiler chickens on a large scale. Klebsiella spp. is an opportunistic pathogen that can induce severe respiratory disease in poultry, carrying a potential risk of zoonotic transmission. Furthermore, the increasing incidence of antibiotic resistance among Klebsiella strains poses a critical challenge to effective therapeutic interventions. This study was conducted to isolate and identify Klebsiella spp. from the gastrointestinal tract of broiler chickens in commercial farms across Bali, and to assess the antimicrobial resistance profiles of the isolates against multiple antibiotic agents. A cross-sectional study with a total of 25 cloacal swabs was conducted, and the swabs were subjected to microbiological analysis. Isolation was performed using selective MacConkey Agar (MCA), followed by Gram staining, biochemical identification, and antibiotic susceptibility testing through the Kirby-Bauer disk diffusion method. Two out of 25 (8%) samples were positively identified as Klebsiella spp. All of these positive isolates showed complete resistance to ampicillin, sulfamethoxazole, erythromycin, ciprofloxacin, and tetracycline. Additionally, the positive isolates also exhibited intermediate resistance against kanamycin, while 50% of the isolates demonstrated susceptibility to chloramphenicol. These findings confirm the presence of multidrug-resistant (MDR) strains among the isolates examined. The outcomes of this research emphasize the urgent need for a rigorous study to identify potential outbreaks caused by Klebsiella spp., throughout commercial farms in Bali and stringent monitoring and regulation of antibiotic usage within the poultry industry to mitigate the proliferation of antimicrobial resistance, thereby safeguarding animal health and preventing potential risks to public health.

Abstract

The Wonocolo traditional oil mining area has oil exploitation activities that have the potential to affect the existence and diversity of soil macrofauna. Soil macrofauna play an essential role in maintaining the balance of the soil ecosystem through the processes of organic matter decomposition, nutrient cycling, and soil structure formation. This study aims to evaluate the Importance Value Index (IVI) of soil macrofauna in the Wonocolo traditional oil mining area and analyze the effect of mining activities on the macrofauna community. The research method employed is a quantitative descriptive approach, utilizing a stratified random sampling technique based on the density of oil wells per hectare. Data were collected through field observations, measurements of soil physical and chemical parameters (pH and temperature), and identification and quantification of soil macrofauna. Data analysis was conducted by calculating the IVI based on the density, frequency of presence, and dominance of each species. The results showed that traditional oil mining activities affected the composition and dominance of soil macrofauna. Several species had high IVI values, indicating their essential role in the soil ecosystem, while other species experienced population declines due to environmental changes. This study concludes that oil mining activities impact the existence and diversity of soil macrofauna; therefore, environmental management efforts are necessary to maintain the balance of the soil ecosystem in the area.

Abstract

Wonocolo Village in Bojonegoro Regency is one of the traditional oil mining areas that still contains old Dutch oil wells. The presence of these wells has the potential to affect groundwater quality. Petroleum that contaminates the soil can seep into groundwater, posing a serious threat to areas that rely on it as a source of clean water. This study aims to evaluate groundwater parameters, including temperature, pH, cadmium, and sulfate, by the standards set by the Indonesian Ministry of Health Regulation No. 32 of 2017, specifically regarding hygiene, sanitation, and public baths. Sampling was conducted using a purposive sampling method at 14 points. Data analysis was performed using the inverse distance weighted (IDW) interpolation method. The results showed that in the densely populated southern part of the study area, the temperature at sampling point SG 13 reached 35°C, and cadmium levels across all samples ranged from 0.059 to 0.156 mg/L, exceeding the permitted quality standards. In contrast, pH and sulfate values met the quality standards set by Permenkes No. 32 of 2017. Therefore, efforts are necessary to reduce cadmium levels in the groundwater of Wonocolo Village, Bojonegoro Regency.

Abstract

Coral reefs are a vital component of marine ecosystems, playing a crucial role in providing and protecting marine biodiversity. However, recent studies have found the presence of microplastics in corals, which have been proven to threaten their health. This study aims to identify the abundance and characteristics of microplastics in coral reefs in the waters of Penimbangan Beach. A total of 12 coral samples were collected from two stations selected based on the presence of coral reefs in the area and then analyzed in the laboratory. Microplastic separation was carried out using hydrochloric acid (HCl) and sodium chloride (NaCl) solutions. Subsequently, an analysis was conducted to determine the abundance and identify the shape, size, and color of the microplastics. The research results showed that the highest microplastic abundance was found at Station 1 (3.5 particles/gram), while the lowest was at Station 2 (1.6 particles/gram). The characteristics of microplastics found were predominantly fibers (94.6%), followed by fragments and granules. The most commonly found microplastic size was 0.001–1 mm (53%), followed by 1–5 mm. The dominant microplastic color was black, followed by blue, red, transparent, and brown.

Abstract

This study investigates the diversity of weeds in rice plants across Minahasa, South Minahasa, North Minahasa, and Tomohon regency, focusing on the environmental factors influencing the distribution and density of weeds. The research highlights that the diversity of weeds is significantly influenced by environmental factors such as rainfall, soil type, and water management practices applied by farmers. Species such as Marsilea crenata and Panicum disticum dominate areas with poor drainage, while Ludwigia hexandra and Fimbristylis litoralis thrive in fields with better drainage. Observations of weed density at 21 and 42 days after planting revealed that the competition between paddy and weeds changes as the paddy plants mature, with the initial dominance of weeds decreasing as the paddy plants grow stronger. The findings provide valuable insights into weed dynamics and the significant role environmental conditions play in determining their distribution. These results offer guidance for developing more effective and environmentally sustainable weed management strategies. Recommendations include selective herbicide use, mechanical soil cultivation, crop rotation, and improved water management. The study also suggests that further research is needed to assess the impact of climate change on weed diversity and the long-term effectiveness of weed management practices.
