Abstract

The carrying capacity of water resources for various uses is highly dependent on the condition of the quality, quantity and continuity of water in a watershed. The lack of research conducted in the Poleang Watershed greatly limits information regarding the carrying capacity of the watershed. This study aims to determine the carrying capacity of the watershed based on water management indicators in the Poleang watershed. The method used in this study uses Minister of Forestry No. P.61/Menhut-II/2014 concerning monitoring and evaluation of watershed management with 5 parameters namely Flow Regime Coefficient, Annual Flow Coefficient, Sediment Load, Flood, and Water Use Index. The results showed that KRA in the Poleang watershed was in the category of KRA ≤ 20 with very low class, KAT was in the category of 0.2 < KAT ≤0.3 with low class, MS reached 97.25 tons/day so it was in the category of M> 20 with very high class, flooding occurs 1 time a year with high class, IPA reaches 1,299.9, so it is in the category of IPA ≤1,700 with very bad class. So that it can be concluded that the carrying capacity of the Poleang water system is included in the medium carrying capacity class

Abstract

ABSTRACT Changes in land use from vegetated land to developed land can reduce environmental quality such as increasing air temperature and trigger disasters such as landslides and floods. Land conversion from vegetated land to developed land have an impact on microclimate changes in urban areas. Analysis to determine the quality of the environment is to identify the environmental criticality index (ECI). ECI is defined as an index to determine critical areas based on the distribution of surface temperature and vegetation cover. The purpose of this study was to analyze the environmental criticality index of Kendari city based on Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) algorithms. Observation of the dynamics of surface temperature and vegetation density in Kendari City in two periods, 2014 and 2021, using Landsat-8 satellite imagery. This study uses Band 10 to estimate the brightness temperature value and convert it to surface temperature and Band 4 and Band 5 to calculate NDVI. In this study, the ECI class was divided into 3 classes, Low, Medium, and High, with range 0–10, 10–30, and > 30 respectively. In 2021, there was an increase in the area that experienced high environmental criticality when compared to the conditions in 2014. The area that experienced a high ECI in 2014 was 11.81 ha, and in 2021 it increasing to 103.95 ha. The increase in the area of high environmental criticality could be caused by changes in LST and vegetation density. ABSTRAK Perubahan alih fungsi lahan dari lahan bervegetasi ke lahan terbangun dapat menurunkan kualitas lingkungan seperti suhu udara yang meningkat dan dapat memicu timbulnya bencana seperti kejadian longsor dan banjir. Alih fungsi lahan dari lahan bervegetasi menjadi lahan terbangun memberi dampak pada perubahan iklim mikro di kawasan perkotaan. Analisis yang dapat dilakukan untuk mengetahui kualitas lingkungan adalah dengan mengidentifikasi Environmental Critical Index (ECI). ECI didefinisikan sebagai indeks untuk menentukan kawasan area kritis berdasarkan distribusi suhu permukaan dan ketersediaan tutupan vegetasi. Tujuan dari penelitian ini adalah untuk menganalisis indeks kekritisan lingkungan Kota Kendari berdasarkan algoritma Land Surface Temperature (LST) dan Normalized Difference Vegetation Index (NDVI). Pengamatan dinamika suhu permukaan dan kerapatan vegetasi di Kota Kendari dilakukan pada dua periode, yakni pada tahun 2014 dan 2021 dengan memanfaatkan citra satelit Landsat-8. Penelitian ini menggunakan Band 10 untuk mengestimasi nilai brightness temperature dan dikonversi ke suhu permukaan serta Band 4 dan Band 5 untuk menghitung NDVI. Pada penelitian ini, kelas ECI dibagi menjadi 3 kelas yaitu Rendah, Sedang, dan Tinggi dengan rentang berturut-turut yaitu 0–10, 10–30, dan > 30. Pada tahun 2021, terjadi peningkatan luas wilayah yang mengalami kekritisan lingkungan yang tinggi bila dibandingkan dengan kondisi di tahun 2014. Peningkatan luasan wilayah yang mengalami ECI tinggi yaitu pada tahun 2014 seluas 11,81 ha mengalami peningkatan luasan pada tahun 2021 menjadi 103,95 ha. Peningkatan luasan wilayah yang mengalami kekritisan lingkungan tinggi dapat diakibatkan oleh perubahan LST dan kerapatan vegetasi.

Abstract

Konversi terhadap lahan-lahan bervegatasi menjadi lahan-lahan terbangun akibat perkembangan kota dan arus urbanisasi dapat memicu terjadinya fenomena urban heat island di beberapa kota di Indonesia. Berdasarkan data peningkatan jumlah penduduk dan ekspansi ruang terbangun yang tidak terkendali di Kota Kendari, ada dugaan bahwa telah terjadi fenomena urban heat island. Mengidentifikasi serta mengukur karakteristik spasial temporal urban heat island sejak dini akan sangat penting bagi pengambil keputusan untuk merumuskan kebijakan demi mencapai tujuan pembangunan berkelanjutan. Penelitian ini bertujuan untuk mengidentifikasi fenomena urban heat island Kota Kendari perode tahun 2001 dan tahun 2019. Metode yang digunakan dalam penelitian ini adalah brightness temperature dengan menggunakan logaritma yang diformulasikan pada alat pengolahan Citra Landsat 7 untuk data tahun 2001 dan Citra Landsat 8 OLI untuk data tahun 2019. Hasil penelitian menunjukan bahwa ekstraksi land surface temperatur menggunakan citra Satelit Landsat-7 tahun 2001 menunjukkan nilai suhu minimum sebesar 19,099 oC dan suhu maksimum sebesar 34,459 oC.  Hasil perhitungan urban heat island treshold sebesar  25,95 0C. Sehingga dengan menentukkan urban heat island index disimpulkan bahwa pada tahun 2001 wilayah Kota Kendari telah mengalami fenomena Urban Heat Island dengan wilayah paparan sebesar 1,021% dari total luas wilayah. Sedangkan pada tahun 2019, ekstraksi land surface temperatur menggunakan citra Satelit Landsat-8 OLI, menunjukkan nilai suhu minimum sebesar 14,27 0C dan suhu udara maksimum sebesar 35, 426 0C. Hasil perhitungan urban heat island treshold sebesar 24,6 0C. Dengan menentukkan urban heat island index disimpulkan bahwa pada tahun 2019 telah terjadi peningkatan fenomena urban heat island dengan wilayah paparan yang lebih luas yakni 18,92% dari luas wilayah.

Abstract

Evapotranspiration plays an important role in agricultural water management and crop modelling. Estimating reference Evapotranspiration (ETo) using meteorological variables, both theoretical and empirical methods, is highly recommended considering the availability of weather data in several locations. The estimation method recommended as the standard method is FAO Penman Monteith (FAOPM), but due to the limited meteorological data in a region and the difficulty and complexity of FAOPM, it is recommended to use the empirical method which is easier and only requires a few simple meteorological variables. The aim of this research is to compare and evaluated empirical methods for estimating ETo against the FAOPM. The statistical analysis using in this research are RSME, MAE, coefficient Correlation, NSE, Average bias, index of agreement, and confidence index (c). Evaluation for the best models based on statistic analyzed shows that several empirical methods show terrible performance in estimating the monthly average ETo (mm/day), which are Thornthwaite-Mather, Hargraves-Samani, Makkink, Hamon, Romaneko, and Kharauffa. Modified Blaney-Criddle method showed a good performance method, while PMAWS showed very good performance The Turc and Hansen method showed excellent performance with RMSE, MAE, NSE, and C values ​​for the Turc method, are 0.12, 0.11, 0.78, 0.92 respectively, and for the Hansen method are 0.12, 0.1, 0.8, and 0.89 respectively.

Abstract

All sectors have realized that waste, especially plastic waste, has become a complex and serious environmental problem, not only in Indonesia, but also around the world. Plastic waste has a major impact on public health and environmental sustainability. In Indonesia, this negative impact is increasingly felt, with an increase in the amount of plastic waste that is not properly managed, polluting nature and damaging ecosystems. For this reason, there needs to be strategic efforts to reduce the use of plastic, one of which is through environmental education. This research explores the role of environmental education as a strategy to instill environmental awareness in students, so that they are more concerned about the impact of plastic waste. The method used in this study is library research, by analyzing various literature and previous research. The results show that environmental education can increase students' awareness of the dangers of plastic waste and the importance of better waste management. In addition, environmental education can also motivate students to apply the 3R (Reduce, Reuse, Recycle) principles in their daily lives. Practice-based learning and real actions have proven to be effective in arousing students' enthusiasm to reduce plastic waste. By involving students in activities directly related to waste management, they can feel the benefits and be motivated to participate in preserving the environment. Sustainable environmental education has great potential in shaping student behavior as agents of change towards a waste-free Indonesia in the future.
