Abstract

The aggressive environment, especially the peat environment contains many chemicals that can unravel the elements in the concrete, causing damage to the concrete. This study examines the strength and physical properties of OPC (Ordinary Portland Cement) concrete and OPC RHA (Rice Husk Ash) concrete exposed in peat environments. RHA as one of pozzolan with high silica is used as a replacement of cement with the substitution of 5% and 10%. This concrete are tested mechanically and physically such as compressive strength and porosity tests after soaking in peat canals for 28 days, in addition to fresh concrete tests such as workability. The concrete strength of the planned concrete is K-250. The peat water used as a test immersion medium has a pH of 3.5-4.5. The results of fresh concrete testing show that the addition of RHA makes the workability decreases. The lowest workability was obtained from a mix containing 10% RHA. The OPC concrete has the highest compressive strength of 20,28 MPa. Porosity of OPC RHA concrete decreased with increase in curing time. The lowest porosity is shown by OPC RHA 10% concrete. Based on the results of the test, it is concluded that the replacement of cement by RHA, has a positive effect on all physical properties of concrete.Keywords: Peat Environtment, OPC, RHA, Compressive strength, Physical Properties

Abstract

The objective of the study is to investigate the mechanical properties of concrete with different replacement levels of Ordinary Portland Cement (OPC) by Rice Husk Ash (RHA). Two RHA replacement levels were considered in the study which is 5% and 10% by the weight of cement. After the specified initial curing period (28 days), specimens were immersed directly in peat water canal for 28 days. The mechanical properties was evaluated by measuring the compressive strength and tensile strength of the concrete specimens. The result shows that the compressive strength of OPC concrete is higher than OPC concrete using RHA as cementitious materials. A replacement level of 10% RHA in OPC concrete performs and shows better tensile strength than other replacements.Keywords : Mechanical properties, OPC, Rice Husk Ash (RHA), peat water

Abstract

Plastik termasuk limbah anorganik bersifat non-biodegradable atau sulit terurai di alam. Berdasarkan data Sustainable Waste Indonesia hanya sekitar 7% yang dapat didaur ulang, sedangkan sisanya menumpuk di tempat pembuangan akhir. Penelitian mengenai beton agregat plastik ini telah berkembang dalam beberapa tahun terakhir misalnya fokus-fokus penelitian plastik sebagai agregat, serat dan bahan pengisi (filler). Kajian ini dilakukan untuk mempelajari karakteristik dan potensi beton ringan agregat plastik sebagai bahan sekat kanal di lingkungan gambut. Sekat kanal pada lahan gambut diperlukan untuk mengatasi kebakaran hutan khususnya lahan gambut yang rawan terjadi saat musim kemarau. Sekat kanal umumnya tidak terbuat dari beton konvensional karena biayanya cukup tinggi, berat volume besar dan porositas mengalami peningkatan apabila berada dalam air gambut dalam jangka waktu panjang. Limbah plastik sudah mulai banyak digunakan sebagai material beton ringan karena dapat meningkatkan kuat lentur, menurunkan porositas dan permeabilitas, mencegah terjadinya keretakan, serta tahan terhadap serangan kimia. Hasil kajian menunjukkan bahwa beton ringan agregat plastik dengan keunggulan sifat mekanik dan durabilitas yang tahan di lingkungan agresif berpotensi digunakan sebagai sekat kanal di lahan gambut karena efisien dan ramah lingkungan

Abstract

Mapping village potential is an important aspect of sustainable rural development. It allows village governments and communities to optimize resource management and improve community welfare. In general, community service activities are designed into three stages, namely preparation, activity implementation, and evaluation and aim to conduct comprehensive village potential mapping. The community service activities involve active participation of the community and village officials in Focus Group Discussions (FGDs) to identify, document, and map all aspects of village potential. This method aims to empower village communities in regional development by producing comprehensive data on existing village potential. The resulting village potential map becomes an invaluable tool for village governments in sustainable development planning and village asset management. Through this village potential mapping, Aur Sati Village is expected to optimize its opportunities to improve community welfare and develop its regional characteristics, including tourism, agriculture, and fisheries potential.

Abstract

Concrete is a common building material and is very vulnerable to cracking caused by unstable temperature/humidity. Concrete crack repair can be done by using microorganism substitution that can produce CaCO3 (calcite) compounds that can be used as an environmentally friendly method in improving structural formation and increasing the strength and durability of concrete, one of which is using ureolytic bacteria. This study aimed to isolate and characterize ureolytic bacteria isolates and then to assess the calcite precipitation potential of ureolytic bacteria isolates from landfills. The ureolytic bacterial isolates were grown on NB-U/Ca and tap water medium. Analysis of Calcite Structure using Fourier Transform Infra-Red (FTIR), and molecular identification using 16S rRNA gene sequences. Bacterial isolate SP. 48 were able to grow and produce calcite in both media, especially in tap water medium. FTIR results showed that the precipitates produced by bacterial isolates on both mediums had strong absorption peaks, which were detected to be calcite. Molecular identification using the 16S rRNA gene sequence showed that the isolate is Bacillus albus. B. albus is a proteolytic bacterium collected from landfills that was proven to be a calcite-producing bacterium, a new finding in this study. B. albus can grow and produce calcite in a tap water medium with low pH. This finding can be used as an alternative to overcome concrete cracks and increase the strength and durability of concrete. This bacterial isolate could be developed as a biocement candidate.

Abstract

Masyarakat Desa Aursati, Kecamatan Tambang, menghadapi keterbatasan dalam mengelola potensi sumber daya lokal yang melimpah, seperti kayu dan cangkang biji karet, sehingga belum mampu memberikan nilai tambah secara ekonomi. Kurangnya keterampilan pengolahan bahan serta belum adanya produk khas daerah menjadi salah satu kendala dalam mendukung sektor pariwisata, khususnya di kawasan Danau Bokuok yang sedang dikembangkan sebagai destinasi wisata desa. Program Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk memberdayakan masyarakat melalui diversifikasi produk lokal menjadi gantungan kunci kreatif berbahan dasar kayu karet, guna mendukung penguatan daya tarik wisata lokal. Metode pelaksanaan kegiatan menggunakan pendekatan partisipatif dan model Participatory Action Research (PAR), meliputi perencanaan, pelatihan, dan implementasi melalui observasi lapangan, sosialisasi, pengenalan bahan baku, pelatihan teknis pembuatan produk gantungan kunci, serta penggunaan alat bahan dan pendampingan. Hasil observasi menunjukkan ketersediaan bahan baku yang melimpah, namun belum dimanfaatkan secara optimal. Melalui pelatihan, peserta yang terdiri dari kelompok ibu-ibu PKK berhasil meningkatkan keterampilan teknis, menghasilkan produk bernilai jual dan mengemasnya secara menarik. Tingginya antusiasme dan komitmen peserta untuk mengembangkan usaha ini menunjukkan bahwa program berhasil meningkatkan kapasitas ekonomi masyarakat sekaligus memperkaya ragam produk cinderamata lokal. Program ini diharapkan dapat menjadi model pemberdayaan berbasis potensi lokal mendukung pengembangan wisata dan ekonomi kreatif desa.
