Abstract

Biological assessment is an option in determining river quality, in this case related to river health. The biological assessment indicators used aquatic macroinvertebrates with research sites in the Pusur River which are located in Boyolali and Klaten Regencies, Central Java Province, Indonesia. The use of macroinvetebrata as an indicator because they are very sensitive to changes in water quality, one of which is the EPT group (Ephemeroptera, Plecoptera, and Trichoptera). Sources of river pollution will affect the existence of EPT and there are macroinvertebrates that are adaptive to contamination. This study was conducted at three monitoring stations located in the Pusur River, namely in the upstream, middle and downstream sections where each station had 6 repetitions in sampling followed by calculating the macroinvertebrate assessment index value. The results of the study show that the upstream station has an index value of 2.11 which means it is moderately polluted, the middle station has an index value of 2.40 which means it is moderately polluted and the downstream station has a value of 2.35 which means it is moderately polluted. From these results it is indicated that contamination into the river has started from the upstream area where the contamination originates from the disposal of unprocessed cow manure into river bodies, while in the middle and downstream areas the contamination that occurs is caused by dumping garbage, household waste and the use of pesticides and chemical fertilizers in agricultural ecosystem.

Abstract

PT. Sewangi Sejati Luhur, a palm oil plantation company, manages 7,000 hectares divided into 12 divisions across 3 estates. The company primarily focuses on cultivating and processing Fresh Fruit Bunches (FFB), with the harvesting unit employing the most workers. This research aims to investigate the implementation of the Occupational Health and Safety (OHS) program within the harvesting unit at PT Sewangi Sejati Luhur, designed to prevent work accidents and occupational diseases. Conducted in Tapung Hulu Subdistrict, Kampar Regency, Riau Province, the study employs a quantitative descriptive method using the HIRARC method to assess OHS application and employee working conditions. A saturated sample of 30 harvesting employees was surveyed through interviews and documentation of the OHS program. The findings reveal that the OHS program includes periodic health exams, OHS awareness campaigns, monthly activities, and training sessions. The program's implementation has led to low accident rates and satisfactory achievement of goals. Correlation analysis shows a significant link between OHS program implementation and improved employee working conditions. Additionally, 82% of respondents reported that the OHS program significantly influenced their working conditions, while 18% cited other factors. Overall, the OHS program in PT Sewangi Sejati Luhur's harvesting unit has been effective, ensuring a low accident rate and meeting monthly targets.

Abstract

Prambanan Biodiversity Park (TKP), Klaten, Central Java, is an important natural reserve for preservation of local biodiversity and environmental protection by PT.Sarihusada Generasi Mahardhika. This research investigates the park's potential in providing food resources and supporting agricultural practices for nearby communities through plant species identification including ecological relationships between species and plants that contribute to pest control in agricultural systems. The collected data provides an overview of the park's biodiversity and serves as a baseline for further analysis. The research finds several potential benefits of utilizing TKP for food resources and agriculture. The diverse flora of the park offers a variety of edible plants, such as Moringa oleifera and fruit-based species, which can enhance local diets and provide nutritional diversity. Furthermore, traditional plants like mojo hold potential as natural pesticides, contributing to pest control in agricultural fields. The research recommends the development of conservation strategies and policies focused on sustainable practices, community participation, and educational initiatives to maximize the potential benefits. TKP emerges as an invaluable resource capable of supplying essential food provisions and supporting eco-friendly agricultural practices for neighboring communities, thereby emphasizing the criticality of interweaving biodiversity preservation within the framework of local food systems.

Abstract

Background: The agricultural areas of Ponjong, Gunungkidul, are dominated by marginal drylands with low soil fertility and organic matter content. Farmers often rely on chemical fertilizers and open burning of crop residues, leading to soil degradation and environmental pollution. Biochar technology offers an eco-friendly solution to improve soil health and reduce waste.Aims: This study aims to strengthen the capacity of the Giri Muda Farmers Group in producing and applying biochar derived from agricultural waste and promoting sustainable soil management practices through participatory technology transfer.Methods: The program was implemented through participatory stages including preparation, socialization, training, demonstration, and field application. The rotary pyrolysis unit was introduced for efficient biochar production using rice straw and maize stalks as feedstock. Evaluation was conducted using pre- and post-tests, observation, and interviews.Results: Farmers demonstrated a 38% improvement in knowledge scores, and 100% of participants were able to operate the pyrolysis equipment independently. Field trials showed improved soil aggregation, higher moisture retention, and more vigorous maize seedling growth on biochar-amended plots. The farmers also committed to continuing biochar production collectively.Conclusion: The community service program successfully transferred appropriate pyrolysis technology to local farmers, improving soil quality, resource efficiency, and community empowerment. The initiative demonstrates that biochar production from agricultural waste can simultaneously address environmental issues and strengthen rural livelihoods.

Abstract

Background of study: Oolong tea is commonly produced from Camellia sinensis leaves, while the use of assamica variety has been rarely investigated. Differences in varietal composition and oxidation duration may influence chemical and sensory characteristics of oolong tea, particularly antioxidant performance and polyphenol content.Aims and scope of paper: This study examined how tea variety and oxidation time affect moisture content, polyphenols, antioxidant activity, and sensory properties of oolong tea. The scope included physicochemical and organoleptic evaluation to determine processing conditions that optimize functional quality.Methods: A randomized block design with two factors was applied, namely variety (sinensis and assamica) and oxidation duration (15, 25, and 60 minutes), each with four replications. Measurements included moisture, polyphenols, antioxidant activity using DPPH, and sensory evaluation of color, aroma, and taste.Result: Variety significantly affected moisture, polyphenols, and antioxidant activity, while sensory differences were observed only in color. Oxidation time significantly influenced antioxidant activity but not moisture or polyphenols. The highest antioxidant activity occurred in assamica at 15 minutes, whereas longer oxidation reduced antioxidant levels.Conclusion: The assamica variety produced higher polyphenol and antioxidant values than sinensis. Shorter oxidation preserved antioxidant activity, indicating that combining appropriate variety selection with controlled oxidation may enhance the functional attributes of oolong tea.
