Abstract

The escalating contamination of heavy metals such as lead (Pb), zinc (Zn), and copper (Cu) in wetland ecosystems poses a significant threat to environmental integrity and public health. This study aims to assess the phytoremediation potential of purun tikus (Eleocharis dulcis) for the accumulation and reduction of these heavy metals in contaminated sediment and water matrices. An experimental approach was employed wherein purun tikus specimens were cultivated for 20 days in media artificially contaminated with varying concentrations of Pb (5, 10, 15 mg/L), Zn (80, 90, 100 mg/L), and Cu (80, 90, 100 mg/L). There was no significant difference (p > 0.05) in the accumulation of heavy metals Pb, Zn, and Cu in the roots, stems, and leaves of purun plants between treatment times of 5, 10, 15, and 20 days. The duration of treatment did not significantly affect the ability of purun plants to accumulate these heavy metals. The descriptive differences seen although not statistically significant are likely due to the small sample size and high variability of the data. The highest removal efficiencies were observed for Pb in stems (95.97%), Zn in roots (81.59%), and Cu in stems (66.10%). These findings indicate that purun tikus exhibits selective metal uptake and distribution mechanisms coupled with high tolerance to heavy metal stress, affirming its efficacy as a phytoremediator for rehabilitating heavy metal-contaminated wetlands and supporting sustainable ecosystem management.

Abstract

Unpredictable climate change impacts several sectors, one of which is the agricultural sector. Extreme climate change causes a decrease in farmer production. The Serayu movable dam area is an area that is prone to flooding, where farmers around this area own land. Farmers can make anticipatory efforts to overcome losses farmers suffer to adapt to the management system and farmer resilience. This study aims to analyze the farm management and factors influencing farmers' adaptation strategies to climate change in the Serayu Dam area. The research was conducted using a descriptive quantitative analytical method. This study used 30 rice farmers as respondents in the Serayu movable dam area. The data analysis method used farm business analysis and logistic regression. The results of the study also stated that the rice farming carried out by farmers earned a profit of IDR 7,639,324 with a total income received by farmers of IDR 10,726,000 and a total farmer expenditure of IDR 3,086,676. Farmers in the Serayu movable dam area have also experienced a decrease in crop production due to climate change. The adaptation strategy carried out by farmers is to postpone or advance planting based on the pranoto mongso used. The results of the study also stated that factors influence farmers' adaptation strategies, namely farmer education, farmer experience, farmer profession as the main job and farmer activity in farmer groups.

Abstract

To effectively educate the future generation, instructors must keep up with the fast-paced global changes by being updated on advancements in science, technology, and educational trends. A very effective lecturer-teacher partnership program (KDS) that utilises lesson study can accomplish this objective. The primary objectives of the KDS are to foster educational innovation, facilitate academic research and publication, and actively involve educators and students in the field of education. The lesson study was carried out within the English Language Education Study Program, including two classes from the third semester of the Creative Writing Course, IIIA and IIIB. The program aims to cultivate and improve students’ social comportment and creative writing skills. Two iterations were carried out, and there was a noticeable augmentation in the students’ sociability from the first iteration to the second. Throughout Cycle 1, students exhibited tolerance and the ability to appreciate their peers’ perspectives. They enthusiastically participated and interacted during the group work. Their average achievement percentage was 67.47% and witnessed a remarkable increase of 85.14% in Cycle 2. The level of collaboration and unity in project completion rose from 57.61% in cycle 1 to 88.99% in cycle 2. The students’ receptiveness to the learning environment significantly increased from 52.09% in cycle 1 to 85.14% in cycle 2. The cognitive domain has significantly enhanced knowledge acquisition, particularly in students’ creative writing skills. The proportion of students in IIIA, exhibiting this proficiency increased from 37% in cycle 1 to 77% in cycle 2. In class IIIB, there was a significant 40% surge, as the percentage escalated from 43% to 83%. Thus, adopting lesson study allows students to improve their social behaviour and support their writing ability.

Abstract

Laporan Keuangan merupakan salah satu unsur yang sangat penting dalam suatu bisnis, karena merupakan sebuah output yang dapat memberikan informasi bagi pengguna sebagai dasar untuk pengambilan keputusan. Oleh karena itu, dalam sebuah organisasi, Lembaga, maupun perusahaan harus memiliki seorang pengelola keuangan yang terampil dan memiliki pengentahuan tentang laporan keuangan. Tetapi, tidak semua orang mengerti dan paham akan pentingnya sebuah laporan keuangan yang sesuai, akibatnya pembuatan laporan keuangan sering kali dibuat seadanya. Seperti halnya Lembaga Kursus dan Pelatihan yang ada di Wakatobi, ternyata mendapatkan kesulitan dalam hal pencatatan laporan keuangan. Kementerian Pendidikan dan Kebudayaan memberikan dana bantuan Program Pendidikan Kecakapan Wirausaha dan Program Pendidikan Kecakapan Kerja kepada Lembaga Kursus dan Pelatihan, program layanan pendidikan melalui kursus dan pelatihan yang diharapkan dapat menghasilkan lulusan kompeten pada bidang keterampilan sesuai kebutuhan sehingga dapat memanfaatkan secara optimal peluang-peluang kerja yang terbuka pada era ACFTA (Asean China Free Trade Area). Setiap dana yang didapatkan harus dilaporkan kembali penggunaannya kepada pemerintah. Namun, sebagian besar dari Lembaga Kursus dan Pelatihan tersebut masih membuat laporan keuangan secara sederhana. Diharapkan dengan adanya sosialisasi dan pelatihan mengenai penyusunan laporan keuangan yang sesuai dengan SAK EMKM, pengurus Lembaga Kursus dan Pelatihan Kabupaten Wakatobi mampu memahami proses dan mampu menyusun laporan penggunaan dana atas transaksi yang sudah dilakukan. Sehingga dapat membuat laporan keuangan yang relevan dan dapat dipertanggungjawabkan.
