Abstract

The existence of water for the life of living things on this earth is very vital, humans in daily life need clean water for consumption, self-cleaning, farming, and other activities. Cilacap has many industries, where many industries bring waste to the waters. The method used for MAP (Magic Adsorbent Pipe) is by coagulating 50 g of rice husk and 50 g of coconut shell, then adding 100 g of coal fly ash, and then making pipe briquettes were made using the addition of aci flour adhesive. After that, the MAP pipes containing 3 kinds of adsorbents were tested for quality by color, pH, BOD, and COD tests. The air tends to be alkaline with a pH of 8 and becomes neutral with a pH of 7. Then the BOD also decreased from 7,442 mg/L to 6,363 mg/L and the amount of COD from 11,107 mg/L to 9,497 mg/L.

Abstract

VCO dapat dibuat dengan berbagai cara sederhana, seperti dengan cara tradisional (pendiaman), metode fermentasi, metode enzimatis, dan ultrasonik. Dalam pengabdian masyarakat di Desa Batuanten Cilongok, Penulis dan Tim mengadakan pelatihan pembuatan VCO dengan 3 metode yaitu, cara tradisional, fermentasi dan enzimatis. Pelatihan pembuatan VCO di desa Batuanten ini bisa menjadi solusi pemberdayaan masyarakat dalam mengolah kelapa agar nilai guna dan nilai jualnya menjadi lebih tinggi, kemudian masyarakat diharapkan bisa secara mandiri membuat VCO yang dapat dikonsumsi pribadi atau dikomersilkan. Tujuan yang hendak dicapai dari kegiatan pengabdian masyarakat kali ini adalah: Memberikan pelatihan pembuatan VCO yang kaya manfaat kepada warga desa Batuanten agar masyarakat bisa membuat VCO secara mandiri. Pelatihan pembuatan VCO kepada ibu–ibu warga desa Bantuanten berlangsung dengan lancar dan dihadiri oleh 44 orang. Semua warga yang mengikuti pelatihan, mempraktikkan langsung membuat VCO dengan bahan santan yang dibawa dari rumah masing-masing. Sebanyak 78% warga berhasil membuat VCO dengan metode yang telah dipaparkan. Saran untuk sosialisasi selanjutnya yaitu pelatihan pengemasan produk VCO beserta informasi mengenai manfaatnya sehingga produk yang di buat ibu–ibu desa Batuanten memiliki merk tersendiri. Pada dasarnya desain kemasan mempengaruhi apa yang ada di dalamnya. Karena itu pengaruh bentuk, warna, bahan, desain kemasan dapat mempengaruhi konsumen.

Abstract

Misconceptions about atomic structure and subatomic particles are a systemic issue in chemistry education, hindering the understanding of advanced concepts and limiting critical thinking. This study aims to identify common misconceptions, explore their root causes, and propose effective corrective strategies. A literature review of 20 peer-reviewed articles was conducted using thematic analysis across three main focuses. Findings reveal that deterministic views of the Bohr model, confusion over technical terms, and misinterpretation of symbolic representations are the most prevalent misconceptions. These stem from unadaptive teaching methods, cognitive limitations, and misleading visuals. Effective remedies include cognitive conflict, dynamic visualizations, and historical-metacognitive approaches to support conceptual change and deepen scientific understanding.

Abstract

The Karangkandri PLTU (Steam Power Plant) Industry in Cilacap is one of the large industries in the Cilacap industrial area, which has abundant coal-burning waste in the form of fly ash. The excess fly ash from PLTU Karangkandri can be used for the adsorption of polluted phosphate ions in the Donan River. The aim of this research is to determine the characterization of fly ash as an adsorbent using FTIR (Fourier Transform Infra-Red), XRD (X-Ray Diffraction), and XRF (X-Ray Fluorescence) instruments and its ability to adsorb phosphate ions in a polluted water sample. The first stage of this research was to take water samples from the Donan River at the 3 most polluted points. The second stage was to activate fly ash using wet grinding and hydrothermal methods as well as characterization of fly ash using FTIR, XRD, and XRF instruments. Then the effectiveness of the fly ash adsorbent in adsorbing phosphate ion was tested by using the spectrometric method. The analysis was carried out with the influence of mass variations in the adsorbent of 50, 100, 150, and 200 grams per 500 ml of water sample. This research found that activated fly ash by greener activation can removed 82,8% phosphate ion with 0,5g fly ash, remove 72.4% phosphate ion with 1 gram fly ash, removed 77.6% phosphate ion with 2 grams of fly ash. And the best one is 5 grams of fly ash can remove 93.2% phosphate ion.
