Abstract

ABSTRAK           Unsur iklim erat hubungannya dengan cuaca yang dapat menurunkan suatu usaha budidaya. Salah satu unsur iklim yang berpengaruh terhadap pertumbuhan dan produktivitas tanaman yaitu angin. Kecepatan angin memegang peran penting dalam evapotranspirasi, karena sebanding dengan evapotranspirasi. Data evapotranspirasi digunakan untuk kepentingan sumber daya air dan menghitung kesetimbangan air khususnya keperluan penentuan kebutuhan air bagi tanaman dalam periode pertumbuhan dan produksi tanaman sorgum. Penelitian ini bertujuan untuk menentukan bagaimana kecepatan angin dan evapotranspirasi mempengaruhi pertumbuhan dan produksi tanaman sorgum. Penelitian dilakukan di lapangan percobaan Stasiun Klimatologi BMKG Aceh, Aceh Besar. Metode penelitian yang digunakan meliputi analisa regresi linier berganda, uji T, uji F, koefisien korelasi dan koefisien determinasi. Parameter penelitian meliputi tinggi tanaman, jumlah daun, berat basah/tanaman dan berat basah/plot. Hasil penelitian menunjukkan bahwa kecepatan angin berpengaruh terhadap bobot basah tanaman dan bobot basah/plot. Evapotranspirasi berpengaruh secara parsial terhadap tinggi tanaman, jumlah daun dan bobot basah/plot. Hasil analisa uji F simultan menunjukkan bahwa kecepatan angin dan evapotranspirasi memiliki pengaruh secara simultan terhadap tinggi tanaman. Kecepatan angin menunjukkan hubungan yang kuat terhadap tinggi tanaman, jumlah daun, dan bobot basah/plot, serta memiliki hubungan yang cukup berarti terhadap terhadap produksi bobot basah tanaman/plot.  ABSTRACT           Climate elements are closely related to weather which can reduce a cultivation business. One of the climate elements that influences plant growth and productivity is wind. Wind speed plays an important role in evapotranspiration, because it is proportional to evapotranspiration. Evapotranspiration data is used for water resources purposes and calculating water balance, especially for determining water needs for plants during the growth and production period of sorghum plants. This research aimed to determine how wind speed and evapotranspiration affect the growth and production of sorghum plants. The research was carried out at the experimental field of the BMKG Aceh Climatology Station, Aceh Besar. The research methods used include multiple linear regression analysis, T test, F test, correlation coefficient and coefficient of determination. Research parameters included plant height, number of leaves, wet weight/plant and wet weight/plot. The results showed that wind speed had an effect on plant wet weight and wet weight/plot. Evapotranspiration partially influences plant height, number of leaves and wet weight/plot. The results of the simultaneous F test analysis showed that wind speed and evapotranspiration had a simultaneous influence on plant height. Wind speed showed a strong relationship with plant height, number of leaves, and fresh weight/plot, and had a significant relationship with the production of fresh weight of plants/plot.

Abstract

ABSTRAKIndustri kertas merupakan salah satu industri penting di Indonesia yang cukup besar kontribusinya terhadap pendapatan negara. Industri kertas menghasilkan limbah yang disebut sebagai sludge. Sludge dapat dikategorikan sebagai limbah organik karena berasal dari kayu dan bubur kertas (pulp) yang diolah untuk menjadi kertas. Akan tetapi limbah tersebut terindikasi mengandung logam berat yang diperlukan sebagai bahan baku dan katalis. Pencemaran logam berat pada lahan pertanian dapat berlanjut pada tercemarnya organ tanaman seperti akar, daun, batang dan gabah yang dihasilkan. Hal ini berbahaya bagi kesehatan lingkungan dan manusia. Tujuan penelitian ini adalah untuk mengkaji unsur cuaca selama pertanaman padi dan kandungan logam berat (Hg, Cd dan Pb) pada tanaman padi (akar, batang, daun dan bulir) di kawasan industri limbah kertas di Kabupaten Malang. Penelitian dilaksanakan dengan mengkaji data cuaca dari BMKG Karangploso dan menguji organ tanaman padi di lahan pertanian di sekitar industri tersebut. Penelitian dilaksanakan Februari-Maret 2024. Hasil penelitian menunjukkan bahwa temperatur rata-rata tertinggi dan temperatur maksimum tertinggi serta lama penyinaran terpanjang dan radiasi matahari tertinggi terjadi pada Oktober 2023 berturut-turut adalah 25.6°C; 32.3°C; 92% dan 445 gr Kal/cm2, sedangkan temperatur minimum tertinggi 21.1°C pada November 2023. Curah hujan tertinggi sebesar 496 mm pada September 2022. Uji laboratorium menunjukkan bahwa logam berat Hg, Cd, dan Pb yang ditemukan pada organ tanaman padi (akar, batang, daun dan bulir) pada lahan pertanian lokasi atas, tengah dan bawah di sekitar industri kertas semuanya berada di atas ambang batas yang diijinkan.  ABSTRACTPaper industry is one of the key industries in Indonesia, significantly contributing to state income. This industry produces waste known as sludge, which can be categorized as organic waste because it comes from wood and pulp processed to make paper. However, this sludge is indicated to contain heavy metals which are needed as raw materials and catalysts. Heavy metal pollution on agricultural land can lead to contamination of plant organs such as roots, leaves, stems and grain produced. This is dangerous for the environment and human health. The aim of this research is to examine weather elements during rice planting and heavy metal content (Hg, Cd and Pb) in rice plants (roots, stems, leaves and grains) in the waste paper industrial area in Malang Regency. The research was carried out by reviewing weather data from BMKG Karangploso and testing rice plant organs on agricultural land around the industry. The research took place in February-March 2024. The results showed that the highest average temperature, highest maximum temperature, longest exposure time, and the highest solar radiation occurred in October 2023, with values of 25.6°C; 32.3°C; 92% and 445 gr Cal/cm2, respectively. Meanwhile, the highest minimum temperature was 21.1°C in November 2023. The highest rainfall was 496 mm in September 2022. Laboratory tests showed that the heavy metals Hg, Cd, and Pb were found in the rice plant organs (roots, stems, leaves and grain) on agricultural land in the upper, middle and lower locations around the paper industry, all exceeding the permitted threshold.
