"Short Time Period Water Budget (SPWB) and Catchment Water Balance (CWB) methods were used for estimating evapotranspiration (ET) rates in oil palm catchments in Johor, Malaysia. Three catchments of different oil palm ages were established, namely C1 (2 years), C2 (5 years) and C3 (9 years). Eight months data of rainfall and runoff were used in the analysis. By adopting no rainfall conditions (Pse=0) at the start and end days of analysis, we obtained water budget periods of 209 days for C1, 111 days for C2, and 158 days for C3. A higher Pse of 2 mm, has prolonged the water budget periods to 218, 206 and 195 days for C1, C2 and C3, respectively. The larger Pse (2mm) also increased the number of samples for analysis. The SPWB method showed more consistent monthly ET compared to the WBC method. The projected rates of annual ET show remarkable variations between catchments, from 927 to 1405 mm/yr for the SPWB method and 1098 to 1365 mm/yr for the CWB method. Although the annual ET rates from C1 (1405 mm/yr for SPWB and 1365 mm/yr for CWB) are reasonable, the ET values in C2 and C3 seemed to be grossly underestimated. Both methods have weaknesses in dealing with distinct dry and wet conditions, most likely due to rapid fluctuation in the soil moisture. This problem is more obvious in the smallest catchment, C2"

"This book is presenting and quantifying it as a catenary process, describing transport of water in the soil, including root extraction patterns and methods of its evaluation. Transport of water through the plant and from the canopy to the atmosphere is also described and quantified. A variety of evapotranspiration (and its components evaporation and transpiration) calculation methods are described, starting from empirical methods up to the most sophisticated ones based on the solution of the transport equations of water and energy in the SPAS.

"Buku yang berjudul "Health and safety at hazardous waste sites : an investigator's and remediator's guide to hazwoper" ini ditulis oleh Steven P. Maslansky dan Carol J. Maslansky. Buku ini membahas tentang faktor-faktor keselamatan dari properti yang berbahaya."

"Seiring berkembangnya penduduk dan teknologi mendorong perubahan besar pada jumlah timbulan sampah yang masuk ke Tempat Pembuangan Akhir (TPA). Dipengaruhi juga oleh pandemi covid-19 yang berlangsung dari tahun 2020 hingga saat ini, penggunaan fasilitas protokol kesehatan seperti masker, memperparah besar timbulan sampah. TPA pada Kecamatan Cipayung merupakan contoh yang terdampak akibat masalah tersebut. Peningkatan limbah masker mengalami kenaikan volume 30 sampai 50 persen dari sebelumnya pada tahun 2020 hanya sebesar 1600 ton limbah infeksius yang berasal dari masker. Timbulan keseluruhan sampah di TPA Cipayung perhari sudah mencapai 1200 m3 /hari di tahun 2021, kondisi ini mengakibatkan TPA overload dan akan direncanakan untuk ditutup. Oleh sebab itu, penelitian ini dilakukan dalam rangka menganalisis dan mengevaluasi komposisi, timbulan, serta kinerja pengelolaan sampah yang berada di TPA Cipayung terdampak pandemi Covid-19. Metode pengumpulan data yang digunakan berdasarkan SNI-19-3964-1994 tentang Metode Pengambilan dan Pengukuran Timbulan dan Komposisi Sampah Perkotaan, observasi kondisi eksisting pada TPA Cipayung serta wawancara kepada petugas TPA. Berdasarkan hasil penelitian, rata-rata volume timbulan sampah yang masuk ke TPA Cipayung sebesar 1031,2 m3 /hari, dengan komposisi yang didominasi sampah organik sebesar 42,02% dan sampah plastik sebesar 26%. Sisa komposisi sampah lainnya terdiri dari sampah B3 berupa baterai, obat dan wadah bekas kosmetik sebesar 9,26 %, sampah kertas sebesar 8,01%, ranting dan kayu sebesar 4,88%, sampah infeksius yang didominasi sampah masker sebesar 4,77%, sampah kain sebesar 3,38%, karet/kulit sebesar 2,27%, kaca sebesar, 1,88%, dan logam 1,19%. Terdapat faktor yang mendorong peningkatan jumlah timbulan yang masuk ke dalam TPA dari aspek peningkatan jumlah penduduk, kegiatan ekonomi, serta aktivitas yang mendorong kuantitas sampah dari rumah tangga meningkat karena keadaan pandemi covid-19.

The amount of waste generated that enters the final disposal site (TPA) changes dramatically as the population grows and technological advances. Also affected by the COVID-19 pandemic that has lasted from 2020 to the present, the use of health protocol facilities such as masks, exacerbates the amount of waste generated. Landfill in Cipayung District is an example that is affected by this problem. Garbage generation at the Cipayung landfill per day has reached 1200 m3/day. This condition has resulted in the landfill being overloaded and it is planned to close it. Therefore, this study was conducted in order to analyze and evaluate the composition, generation, and performance of waste management at the Cipayung TPA affected by the Covid-19 pandemic. The data collection method used was based on SNI-19-3964-1994 regarding Methods of Collection and Measurement of Urban Waste Generation and Materials, observations of the existing conditions at the Cipayung landfill, and interviews with landfill officers. Based on the results of the study, the average volume of waste that enters the landfill is 1031.2 m3/day, with a composition dominated by organic waste (42.02%) and plastic waste (26%). The remaining composition of other waste consists of B3 waste in the form of batteries, drugs, and used cosmetic containers by 9.26%, paper waste by 8.01%, twigs and wood by 4.88%, infectious waste dominated by mask waste by 4.77%, cloth waste by 3.38%, rubber/leather by 2.27%, glass by 1.88%, and metal by 1.19%. There are factors that encourage an increase in the amount of generation that goes into the landfill from the aspect of increasing population, economic activity, and activities that support the quantity of waste from households increasing due to the COVID-19 pandemic."
