Abstract

Efforts to manage waste are being undertaken at all levels, from households to large factories that produce waste daily. The imbalance between waste production and management has made waste a significant environmental issue. One of the most challenging types of waste to decompose naturally (non-biodegradable) is plastic waste, which constitutes the largest quantity compared to other types of waste. According to statistical data, the amount of non-biodegradable waste disposed of daily at final disposal sites in several cities in Indonesia is 6,598.23 tons per day. This research has both general and specific objectives. The general objective is to utilize plastic waste as a material for making paving blocks, while the specific objective is to analyze the compressive strength properties of paving blocks made from plastic waste. By exploring the potential of plastic waste in construction materials, this study aims to provide a sustainable solution to the plastic waste problem and contribute to environmental preservation. This study used 4 types of specimens where Specimen A consisted of 80% plastic waste and 20% glass powder. Specimen B consisted of 60% plastic waste and 40% glass powder, Specimen C consisted of 40% plastic waste and 60% glass powder, Specimen D consists of 20% plastic waste and 80% glass powder. The research results showed that Specimen B achieved the highest average compressive strength value of 10.9 Mpa, indicating significant potential in supporting material strength. On the other hand, Specimen D showed the lowest average compressive strength value with only 1.2 Mpa, indicating the need for further composition adjustments to increase the material's strength. This research provides valuable insight into developing recycled materials for construction and other industrial applications.

Abstract

Kesadaran masyarakat memanfaatkan sampah menjadi sesuatu yang tidak ekonomis menjadi ekonomis sangatlah kurang. Oleh karena itu, maka diberikanlah pelatihan kepada ibu-ibu rumah tangga dan remaja putri di RT 02/04 dan RT 04/Rw 04 Kelurahan Batang Arau Padang agar dapat mengolah sampah organik menjadi sesuatu yang mempunyai nilai jual tinggi. Solusi untuk menyelesaikan permasalahan ini adalah dengan membuat Reaktor Biokompos Hi. Hasil dari Reaktor Biokompos Hi adalah pupuk organik cair, larva lalat BSF dan kompos. Ketiga hasil dari Reaktor Biokompos Hi sangat mempunyai daya jual yang tinggi. Misal pupuk organik cair dapat dijual sebagai pupuk tanaman, larva Black Soldier Fly BSF dapat dijual untuk pakan ikan atau burung, sedangkan kompos padatan dari sisa sampah organik bisa digunakan untuk sarana temapt berkembang biaknya cacing tanah. Kegiatan PKM ini dilaksanakan pada tanggal 14 Oktober 2021 yang dihadiri oleh 20 ibu-ibu rumah tangga dan remaja putri. Kegiatan ini dilakukan dengan metode penyuluhan dan praktek.

Abstract

Batanta Island in Raja Ampat, West Papua, is located in an active tectonic zone dominated by fault structures and igneous rock intrusions, thus possessing significant geological potential. This research aims to identify the subsurface structure of the island using the gravity method that has undergone drift, tidal, topographic, and Bouguer corrections, followed by regional-residual component separation. 2D modeling with GM-SYS software was used to construct geological cross-sections based on rock density distribution. Results show the presence of several main units, including massive lava, breccia, Quaternary deposits, and high-density intrusion bodies (±3.00 g/cm³) that are interpreted as diorite. An active fault zone and lithological boundary were also found, which serve as the main controllers of geological structure. These findings indicate the presence of mineralization potential and complex geological dynamics, and serve as an important initial contribution to further geological exploration on Batanta Island and its surroundings

Abstract

Land cover change represents a dynamic phenomenon driven by human activities and rapid regional growth, particularly in Palangka Raya City. This study aimed to analyze the historical dynamics of land cover changes during the 2016–2020 period and predict development trends for 2028 and 2040. The methodology integrated Cellular Automata and Artificial Neural Network (CA-ANN) models utilizing the MOLUSCE plugin within Geographic Information System software. Several driving factors were incorporated into the modeling process, including distance from road networks, distance from rivers, slope, elevation, and population density. The analysis revealed a significant transition from natural vegetated areas, such as peat swamp forests and shrublands, into anthropogenic land uses, specifically oil palm plantations and built-up areas. Model validation was performed using the Kappa coefficient test, which yielded a high level of accuracy, thereby confirming the reliability of the model for spatial projection purposes. The prediction results for 2028 and 2040 provided critical spatial insights regarding the potential continuous expansion of built-up areas. These findings were intended to serve as a crucial reference for local governments in formulating sustainable spatial planning policies to mitigate future environmental degradation.
