Abstract

Cultivated paddy fields that applied in Indonesia currently produces high emissions of greenhouse gases (GHG), particularly methane gas (CH4). This research aimed to analyze CH4 gas emission in various water management, and to develop DNDC model in predicting CH4 gas emission. This research was conducted from January to May 2018, located at field laboratory of Departement of Civil and Environmental Engineering. The research was conducted by three water regimes i.e., continuously flooded (RT) for conventional rice farming, wet regime (RB), and dry regime (RK) for system of rice intensification (SRI). The highest total methane (CH4) flux was 48.74 kg/ha on RT, on RB was 3.59 kg/ha and on RK -5.40 kg/ha. DNDC model needed data inputs of climate, soil physics, vegetation and anthropogenic activities. The result of the DNDC model showed that the highest total CH4 flux was 44.44 kg/ha on RT, on RB was 17.88 kg/ha and on RK was 0.02 kg/ha. The result, of total actual of CH4 gas flux was compared with DNDC model and got the coefficient of determination (R2) values 0.93, so the model could be used to predict total CH4 gas emission.Keywords: DNDC, methane gas, paddy field, water regime.

Abstract

PT. Indonesia Power UPJP Priok is a power generation industry that manages wastewater by a wastewater treatment plant (WWTP). Analysis of wastewater quality and removal efficiency (RE) needs to be conducted to fulfill the quality standards. This study aimed to analyze water quality and removal efficiency of WWTP. The materials used in the study was wastewater laboratory test results for 5 years. The results showed that the pH, TSS, oil and fat contents, Cl2, Cr, Cu, Fe, Zn, and phosphate in the inlet decreased after the processing at WWTP. The waste output at WWTP had fulfilled the quality standard. The highest RE unit value of WWTP for TSS, oil and fat, Cl2, Cr, Cu, Fe, Zn, and phosphate were 21.3%, 2.4%, 12.5 %, 15.6%, 7.8%, 25.7%, 5.7%, and 46.2%. WWTP RE values between years do not differ significantly. However, RE values in several years showed that WWTP units were less efficient which were showed by low RE values. WWTP units should be maintained every two years.

Abstract

The approach to calculating evaporation and evapotranspiration, both potential and actual, varies widely. The models used to estimate the amount of evapotranspiration, particularly at the Maros Climatology Station, Maros Regency, South Sulawesi. Evaporation models use the Penman, Priestley, Bruin, and Valiantzas models while evapotranspiration models use the Penman, Hargreaves, Jensen-Haise, Penman-Monteith, Radiation, Turc, and Makkink models, where all of these methods use climate data, such as are the minimum temperature (Tn), maximum temperature (Tx), air temperature (Ta), average humidity (RH), rainfall (R), duration of sun exposure (SS), and maximum wind speed (U) in calculations using Visual basic program in Microsoft Excel in the form of code. Thus, it is necessary to conduct an analysis of the suitability of the model to the results of the observations in order to find out which model is suitable according to the results of the largest coefficient of determination (R2). Based on the results of the model suitability analysis, a selected model was obtained, namely the Valiantzas model with a value of 0.980 in the evaporation calculation and the Jensen-Haise model, namely 0.889.

Abstract

A review of air temperature in the Palembang city by reviewing data from the National Agency for Meteorology, Climatology, and Geophysics/BMKG (Kenten Climatology Station and the SMB II Meteorological Station) shows a difference in air temperature can indicate the occurrence of Urban Heat Island (UHI). The difference in air temperature affects the evapotranspiration rate (ET) because air temperature very influencing water evaporation. ET rate estimation with air temperature data is the first step to prove this hypothesis. Hargreaves and Samani, Blaney and Criddle, Linacre, and Kharuffa models is the ET model that using air temperature as the variable was used to estimate the ET rate. Air temperature data used in the period 2011-2020 by reviewing data from the Kenten Climatology Station and the SMB II Meteorological Station. The results of this study of air temperature data from the Kenten Climatology Station and the SMB II Meteorology Station showed a difference in air temperature with the minimum ∆T of 0.42 oC, the maximum of 0.43 oC, and the daily average of 0.41 oC. This difference in air temperature has an impact on the difference in the ET rate with the average ∆ET of the Hargreaves and Samani model of 0.05 mm/day, the Blaney and Criddle model of 0.05 mm/day, the Linacre model of 0.06 mm/day, and the Kharuffa model of 0.14 mm/day. The results of this study predicted that an increase in air temperature causes an increase in the ET rate of ± 10-30%.

Abstract

Water is one of the basic necessities used by living things on this earth. Along with the population growth with climate change, there are several cases of water crisis in Java and Bali, especially in the dry season. The purpose of this research is to project water demand and availability based on climate change scenarios, develop an analysis model for the impact of climate change on the water sector based on the water balance, and calculate environmental economic losses resulting from water deficit losses. The type of scenario used in climate analysis is RCP (Representative Carbon Pathway) 4.5 with two types of models. Provinces experiencing very critical water conditions in the 2021-2050 period using the CSIRO model are DKI Jakarta, East Java and Bali, with water criticality indexes of 296.25%, 113.88% and 123.64%, with a water deficit loss of IDR 1.2 billion, IDR 7.93 billion and IDR 0.87 billion. Whereas with the MIROC model, the areas that have very critical water conditions are DKI Jakarta Province with a water criticality index of 220.36%, with a water deficit loss of IDR 0.42 billion.

Abstract

Estimation of evaporation rate is needed in hydrological data, especially in irrigation and drainage planning data. The method for estimating the evapotranspiration rate recommended by FAO is the Penman - Monteith method, however apart from this method there are still several methods that can be used if the data obtained in the field are different. Evaluation of the method of estimating the rate of evapotranspration is expected to help in choosing the right method when different data is obtained, so with this evaluation, we can see the accuracy of the methods. The methods that are closest to accuracy with the Penman - Monteith method are Hargreaves, Makkink, Turc, Blaney-Cridlle and Penman. If ordered based on the ranking of the evaluation results, the method that is closest to the Penman - Monteith method is Hargreaves, because of all the evaluation variabels Hargreaves has the best evaluation value. While the closest model based on the best R2 value is the Jensen-Haise model, but the error value of this model is very high.

Abstract

Pemanasan Global merupakan isu lingkungan yang menjadi perhatian banyak negara saat ini. Inventarisasi emisi gas rumah kaca (GRK) dapat ditentukan dari beberapa sektor di suatu wilayah. Penelitian ini bertujuan untuk menentukan dan membandingkan emisi GRK antara tahun 2012, 2014 dan 2020 di Kota Bogor berdasarkan peta tata guna lahan, dan memberikan rekomendasi untuk mitigasi emisi GRK pada aktivitas beberapa sector berdasarkan kriteria IPCC. Data sekunder seperti data aktivitas sektor dan peta tata guna lahan dari Kota Bogor digunakan untuk menentukan jumlah emisi GRK dengan metode IPCC 2006 tier-1, kemudian menganalisis tata guna lahan dengan menggunakan ArcGIS. Hasil studi menunjukkan bahwa perumahan dan taman mendominasi tata guna lahan di Kota Bogor. Inventarisasi emisi GRK menunjukkan peningkatan dari 1,44 juta ton CO2 ekuivalen pada tahun 2012 meningkat menjadi 1,48 juta ton CO2 ekuivalen pada tahun 2014, dan menurun menjadi 1,02 juta ton CO2 ekuivalen pada tahun 2020. Penurunan emisi pada tahun 2020 ditengarai karena pandemik Covid-19 yang berdampak pada penurunan aktivitas khususnya transportasi. Meskipun terjadi penurunan, langkah mitigasi emisi GRK tetap diperlukan khususnya apabila pandemic telah berakhir.

Abstract

Optimasi dalam sistem irigasi masih menjadi persoalan dalam budidaya tanaman hortikultura yang efektif dan efisien dalam penggunaan air. Penelitian ini bertujuan untuk menentukan sistem irigasi bawah permukaan dalam meningkatkan produktifitas tanaman dan air dengan metode algoritma genetika (AG). Untuk mendapatkan data optimasi, skenario sistem irigasi dibagi menjadi 3 tinggi muka air (TMA) pada bak kontrol, yaitu 13 cm (TMA1), 10 cm (TMA2) dan 7 cm (TMA3). Dari hasil observasi menunjukkan bahwa produktivitas air (WP) tertinggi terjadi pada TMA2 sebesar 1,60 kg/m3, diikuti oleh TMA 3 dan TMA 1. Akan tetapi, dari hasil pemodelan AG didapatkan bahwa TMA yang optimum adalah 12,8 cm, 7 cm, 7,2 cm pada fase awal, tengah musim dan akhir musim. Dengan skenario ini akan didapatkan WP sebesar 1,96 kg/m3, dimana nilai ini 22,5 % lebih besar dibandingkan WP pada skenario TMA2. Oleh sebab itu, untuk membuktikan hasil pemodelan ini, perlu dilakukan uji lapangan

Abstract

Dalam usaha peningkatan produksi padi, faktor-faktor lingkungan yang ada di sekitar tanaman perlu diperhatikan. Salah satu faktor yang berpengaruh terhadap produktivitas padi yaitu jumlah dan kualitas air yang dialirkan harus disesuaikan dengan kebutuhan padi. Kandungan oksigen yang terdapat dalam air juga perlu diperhatikan karena kebutuhannya untuk proses metabolisme dan pertumbuhan padi. Selain itu, faktor lingkungan lain seperti evapotranspirasi tanaman, suhu, kelembapan, dan konduktivitas listrik tanah juga dapat mempengaruhi produktivitas padi. Penelitian ini bertujuan untuk mengembangkan model hubungan antara tinggi muka air, oksigen terlarut, evapotranspirasi tanaman dengan produktivitas padi dengan Jaringan Saraf Tiruan (JST). Model JST digunakan untuk membantu memodelkan kompleksitas pengaruh faktor-faktor lingkungan tersebut sebagai input terhadap produktivitas padi sebagai output. Penelitian ini dilakukan dengan menggunakan 4 skenario perlakuan berdasarkan tinggi muka air, sistem pengaliran irigasi, dan penggunaan teknologi ultra fine bubble untuk meningkatkan oksigen terlarut. Hasil pemodelan JST menunjukkan bahwa model yang dikembangkan mampu menduga pertumbuhan tanaman dengan dengan koefisien determinasi (R2) sebesar 0,9991. Hasil ini menunjukkan bahwa model dapat digunakan dan dapat dijadikan acuan untuk optimasi sistem irigasi berdasarkan faktor lingkungan
