Abstract

To improve environmental health and address the issue of domestic fecal sludge waste, it is essential to treat the waste using an environmentally friendly organic oxidizing material, BIOSEL-SR2020. This study examines the effect of adding BIOSEL-SR2020 to reduce the physicochemical content of fecal sludge at the Puulonggida sludge treatment plant (STP) in Kendari City and its potential as a component of organic fertilizer. The environmental condition of Puulonggida STP shows that the air quality around the STP is excellent. The area is far from residential zones and features numerous trees, which help transform the toxic gases produced by septage treatment. The application of BIOSEL-SR2020 to septage solids significantly alters and enhances the chemical elements in the septage. Oxide composition data, such as MgO, Al2O3, SiO2, and CaO—soil components—indicate that BIOSEL-SR2020 application significantly improves chili plant growth compared to commercial organic fertilizer and untreated samples. Furthermore, treating fecal sludge liquids with BIOSEL-SR2020 affects the pH, maintaining a standard range of 7.06 - 7.13. The Dissolved Oxygen (DO) value increases slightly, and the fecal liquid’s salinity indicates no mineral salts. BIOSEL-SR2020 also demonstrates antibacterial properties, reducing bacterial colonies by an average of 26%. The most prevalent bacteria, Klebsiella sp., and Pseudomonas sp. are effective in decomposing fecal organic matter at the Puulonggida STP. In conclusion, BIOSEL-SR2020 effectively enhances the physicochemical properties of fecal sludge and holds potential as a mixture in organic fertilizers, significantly benefiting plant growth and environmental health.

Abstract

Pentingnya mengetahui kandungan logam nikel (Ni) dalam air laut dan persebarannya disekitaran Teluk Kendari, Sulawesi Tenggara karena kebolehjadian terjadinya pencemaran limbah domestik dan akumulasi sedimentasi di badan perairan yang terbawa melalui aliran sungai dan drainase perkotaan. Penelitian ini menyajikan beberapa korelasi antara aktivitas keramaian masyarakat dengan tingkat kandungan logam Ni disekitaran Teluk Kendari yang dianalisis menggunakan instrumentasi spektroskopi serapan atom (SSA). Penentuan 5 titik lokasi berbeda dipilih berdasarkan banyaknya kegiatan aktivitas masyarakat. Selanjutnya, sampel diambil masing-masing sebanyak 1 Liter sejauh ±100 m dari garis pantai yang selanjutnya dianalisis menggunakan instrument SSA. Hasil penelitian menunjukkan bahwa adanya hubungan aktivitas keramaian kegiatan masyarakat terhadap tingginya kandungan logam Ni yang terakumulasi dalam air laut Teluk Kendari. Kandungan logam Ni yang diperoleh bervariasi berturut-turut T1< T4< T3< T2> T5 yaitu 0,047; 0,052; 0,063; 0,068; 0,073. Berdasarkan baku mutu, standar kandungan Ni dalam air laut sebesar 0,05 mg/L, sehingga pada T2, T3, T4, dan T5 dinyatakan telah melebihi ambang batas. Hal ini disebabkan lokasi tersebut maraknya aktivitas masyarakat sehingga kebolehjadian nilai logam Ni juga meningkat.

Abstract

Importantly to study the coastal vegetation from Kekara Laut (Canavalia maritima Thou.) to observe the antibacterial agents towards Staphylococcus epidermidis. The purpose of this study to examine the variation concentration effect of an ethanol leaf extract from Canavalia maritima Thou. in inhibiting the growth of S. epiderimidis bacteria. The leaf of Canavalia maritima Thou. was prepared using a physicochemical method to obtain ethanol extract, then varied in several concentrations, namely 5% w/v; 10% w/v; 15% w/v; and 20% w/v. Based on these results, we obtain the ethanol leaf extract can inhibit the growth of S. epidermidis with a concentration of 15% w/v for 24 hours having an inhibition zone of 17.17 mm. The statistical analysis test was very significantly different from all antibacterial tests, the value of F count was 682.1 with F table (3.48), at the level of α = 0.05 (3.48) and α = 0.01 (5.99), which indicates that H0 is rejected, but using the Variance method in the Newman-Keuls range approach shows that each concentration has a good inhibitory ability. The use of Canavalia maritima Thou. leaf extract in low concentrations can significantly inhibit bacterial growth (bacteriostatic).

Abstract

ABSTRAKPenelitian fundamental mengenai produksi gas HCHO dan TVOC dapat digunakan sebagai parameter untuk menentukan laju pertumbuhan bakteri dalam proses fermentasi limbah cair tahu. Maka penelitian ini bertujuan untuk mengidentifikasi optimasi produksi biogas dari limbah cair tahu melalui fermentasi anaerobik. Limbah cair tahu dihasilkan dari berbagai tahap proses pembuatan tahu dan mengandung senyawa nitrogen dan fosfat yang tinggi, menyebabkan bau tidak sedap dan potensi eutrofikasi. Hasil penelitian menunjukkan bahwa suhu optimal untuk fermentasi biogas berada pada kisaran 20-35°C, dengan suhu optimal dalam digester sekitar 28°C. Pengukuran pH menggunakan pH meter menunjukkan bahwa kondisi optimal pH untuk produksi biogas adalah pada hari ke-4 dengan nilai 10,9. Bakteri metanogen yang dominan dalam fermentasi biogas lebih efisien pada kondisi pH basa. Kinerja fermentasi dan produksi biogas dipengaruhi oleh perubahan pH dan suhu. Kecepatan fermentasi menunjukkan peningkatan pada awal proses, tetapi cenderung menurun setelah beberapa hari karena berkurangnya sumber nutrisi. Berdasarkan analisis linearitas, peningkatan laju fermentasi memiliki hubungan yang cukup signifikan dengan produksi biogas, namun masih memerlukan penyesuaian kondisi lingkungan. Penelitian ini memberikan pemahaman penting dalam optimasi produksi biogas dari limbah cair tahu dengan mempertimbangkan faktor-faktor pH dan suhu, yang dapat berkontribusi pada lingkungan yang lebih berkelanjutan.Kata kunci: Tahu, Limbah, Bakteri, Gas, OptimasiABSTRACTFundamental research of HCHO and TVOC gas production can serve as a parameter for determining the bacterial growth rate in the fermentation process of tofu liquid waste. So, this study aims to identify the optimization of biogas production from tofu liquid waste through anaerobic fermentation. Tofu liquid waste is generated from various stages of the manufacturing process and contains high nitrogen and phosphate compounds, causing an unpleasant odor and potential eutrophication. The results showed that the optimal temperature for biogas fermentation is 20-35°C, with the optimal temperature in the digester around 28°C. The pH meter measurement showed that the optimal pH condition for biogas production was on day 4, with a value of 10.9. The dominant methanogen bacteria in biogas fermentation are more efficient in alkaline pH conditions. Fermentation performance and biogas production were affected by changes in pH and temperature. Fermentation speed increased at the beginning of the process but tended to decrease after a few days due to the reduction of nutrient sources. Based on linearity analysis, increasing fermentation rate has a significant relationship with biogas production but still requires adjustment of environmental conditions. This study provides important insights into optimizing biogas production from tofu wastewater by considering pH and temperature factors, which can contribute to a more sustainable environment.Keywords: Tofu, Waste, Bacteria, Gas, Optimization

Abstract

Noise is a sound wave generated from a vibrating sound source that causes discomfort to the listener and has an effect on health. Traffic activity is one of the sources of noise and disturbs the comfort of school children. Therefore, this study aims to analyze the noise potential in elementary schools (SD) on the edge of the Kendari City primary road mathematically, then map the results of noise calculations. The sampling technique was carried out by calculating the volume of traffic vehicles such as motorcycles, light vehicles, and heavy vehicles. Measurements were carried out on Monday-Friday at each point one day, the measurement time was at 08.00 - 09.00 WITA. Travel time is done by recording the time required to pass the road segment. Based on these results that the Predicted Noise Level (PNL) calculation, the highest potential noise level is at SDN 7 Kendari at 67.09 dB(A), SDN 37 Kendari at 66.53 dB(A), SDN 6 Kendari at 65, 05 dB(A), SDN 2 Kendari is 64.84 dB(A), SDN 30 Kendari is 64.53 dB(A), and SDN 28 Kendari is 62.48 dB(A). The presentation of data in the form of spatial/map data is very important because of the large number of research locations, with the presentation of the data in the form of a map, making it easier for researchers to analyze the noise potential by making points, so that they become reference materials for the great potential of PNL in Kendari City.

Abstract

An increase in population leads to an increase in waste generation, which has the potential to cause negative impacts on health and the environment. Waste management in rural areas is important to reduce air pollution due to waste burning and soil pollution, while providing economic value through the development of Reduce, Reuse, Recycle Waste Processing Site (3R WPS). This study aims to estimate waste generation using a dynamic system approach, design an environmentally based 3R WPS design, and evaluate the perception of social acceptance of the community in Pesue Village, Konawe Islands Regency, Southeast Sulawesi. The dynamic system approach was used to project the amount of waste, while the design of 3R WPS was designed using AutoCAD. The community's perception of the acceptability of 3R WPS was evaluated through a questionnaire survey. The simulation results show that the population growth of Pesue Village follows a sigmoid graph pattern in the 2021-2050 projection, and a linear pattern in the 2021-2030 period. The increase in population is in line with the increase in waste generation, which is depicted in a linear graph pattern. Simulation of waste management with 3R WPS shows that this facility can significantly reduce waste generation. The survey results show that the community supports the development of 3R WPS with the hope that waste management is carried out properly and sustainably. Implementation of the 3R principles (Reduce, Reuse, Recycle) is recommended to ensure environmentally friendly waste management, thus supporting the creation of a clean and healthy environment.

Abstract

The performance assessment of the Wolo Irrigation Area (WIA) is crucial for ensuring efficient water management and sustainable agricultural productivity. This study evaluates WIA’s operational performance using the e-PAKSI or eA-AMPIS application as a digital platform designed for integrated irrigation performance monitoring. The assessment results show a performance index of 60.44%, indicating that several functional aspects require improvement. Unlike previous studies that relied solely on manual field evaluation, this research integrates digital data collection through electronic Performance Assessment and Irrigation System Information (e-PAKSI) to provide more accurate, real-time, and traceable performance indicators. The findings highlight the need for targeted management strategies focusing on infrastructure maintenance, operational efficiency, and community-based institutional strengthening. Implementing these strategies can enhance WIA’s functionality and support sustainable irrigation management in similar regional systems.

Abstract

The application of a simple geometric concept to design a domestic wastewater treatment plant (WTP) is important because it refers to a three-dimensional spatial structure to construct a storage tank. Thus in this study, we apply a simple geometric system for the design of the reservoir design which can be applied in several simple housing areas (Perumahan Mutiara Sartika-Kendari City). The results show that with the need for clean water consumption of 150 L/day/person with 68 housing types 36 and 5 people/house, the amount of waste generated is 40.8 m3/day. So that the dimensions of the wastewater reservoir built are rectangular with a total volume of 79.1 m3 with an estimated residence time of 29 hours taking into account several functions of the treatment unit. Based on the results of this study, it is hoped that it can help to apply a simple WTP design for housing development.
