Abstract

This study examined the relationship between the decline in sugarcane productivity and the distribution of macropores and depth of root penetration in sugarcane plantations in Takalar during one planting period (October 2021-September 2022). There were five observation points (P1, P2, P3, P4, and P5) in one hectare of land to measure the distribution of soil macropores using methylene blue solution. Cross-sections of the soil were made to observe the presence of plant roots at a depth of 0-40 cm with a width of 60 cm. In each plot, disturbed soil samples were collected to measure soil texture, soil organic matter (SOM), nitrogen (N), phosphorus (P), and potassium (K) contents. Other measurement parameters were the infiltration rate and plant productivity. The results indicated that SOM and NPK levels at the research location were deficient, serving as the first indicators of problematic soil. Macropore observations revealed that macropores were distributed only at a less than 10 cm soil depth. This distribution limited the penetration of plant roots to a depth of   0-40 cm. The root length density (RLD) value indicated the absence of roots at depths of 30-40 cm in plots P2 and P3. The field findings explained why sugarcane production in Takalar only achieved 50%, around 40 t ha-1 from the first ratoon sugarcane harvest, instead of the expected 70-80 t ha-1.

Abstract

Marginal soil with low nutrient content is a crucial problem in reducing crop productivity, including sugarcane. This study aimed to elucidate the possible improvement of the physical and chemical properties of marginal soil through the application of organic waste from sugar factories, namely kettle ash and press mud. Nine treatment combinations of 0, 10, and 20 t ha-1 of each kettle ash and press mud were arranged in a two-factor randomized factorial design with three replications. Soil organic matter, N, P, and K, soil aggregate stability, and sugarcane productivity were measured after planting sugarcane for five months. The results showed that the application of kettle ash and press mud, especially with a ratio of 20 t ha-1 kettle ash and 10 t ha-1 press mud, was able to reduce the leaching of organic matter and improve sugarcane growth, particularly increasing the number of tillers by 16%, stem height by 14%, and diameter by 16%. The sugarcane productivity obtained was 58.02 t ha-1. Other portions of kettle ash and press mud did not have a favorable effect on sugarcane productivity. This study provided practical insights for increasing agricultural productivity, especially in sugarcane plantations.

Abstract

AbstrakPendidikan karakter mandiri adalah komponen yang paling penting dalam motivasi belajar. Mahasiswa yang termotivasi akan menunjukkan minatnya untuk melakukan aktivitas belajar, merasakan keberhasilan diri, mempunyai usaha-usaha untuk sukses dalam menyelesaikan tugasnya. Kemandirian adalah kebebasan individu untuk memilih dan menentukan dirinya sendiri. Pendidikan karakter sangat penting untuk diterapkan setiap mahasiswa. Permasalahan yang dikaji dalam penelitian ini adalah: ada tidaknya hubungan Pendidikan karakter dengan motivasi mahasiswa dimasa pandemi covid-19 serta seberapa besar hubungan Pendidikan karakter dengan motivasi mahasiswa dimasa pandemi covid-19. Penelitian ini merupakan penelitian kualitatif teknik pengumpulan data secara deskriptif. Analisis data yang dilakukan bersifat induktif berdasarkan fakta-fakta yang ditemukan di lapangan. Dari hasil penelitian menunjukkan bahwa terdapat hubungan antara Pendidikan karakter mandiri dengan motivasi belajar mahasiswa, dimana dapat dijelaskan perkuliahan mahasiswa akan optimal apabila karakter mandiri dan motivasi belajar mahasiswa baik. Namun, jika karakter mandirinya kurang baik maka motivasi belajarnya juga akan kurang optimal.Kata Kunci: Pendidikan, Karakter Mandiri, Motivasi Belajar. AbstractIndependent character education is the most important component in learning motivation. Motivated students will show their interest in doing learning activities, feel self-success, have efforts to be successful in completing their tasks. Independence is the freedom of the individual to choose and determine himself. Character education is very important for every student to apply. The problems studied in this study are: whether there is a relationship between character education and student motivation during the Covid-19 pandemic and how much character education has to do with student motivation during the Covid-19 pandemic. This research is a qualitative research on descriptive data collection techniques. The data analysis carried out is inductive based on the facts found in the field. From the results of the study, it shows that there is a relationship between independent character education and student learning motivation, where it can be explained that student lectures will be optimal if the independent character and student learning motivation are good. However, if the independent character is not good, the motivation for learning will also be less than optimal.Keywords: Education, Independent Character, Motivation to Learn
