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

Temperatur udara menjadi salah satu faktor paling penting yang mempengaruhi sifat mekanis campuran aspal, sehingga semakin tinggi suhu udara disuatu tempat maka semakin tinggi suhu perkerasan aspal yang berada di daerah tersebut. Peningkatan suhu dan waktu pembebanan yang lama dapat mempengaruhi tingkat deformasi pada struktur lapisan perkerasan aspal serta karakteristik distribusi bebannya. Ketika suhu meningkat dan waktu pembebanan menjadi lebih lama, nilai modulus kekakuan campuran beraspal mengalami penurunan yang signifikan. Hal ini menyebabkan perkerasan aspal mengalami deformasi berlebih, yang dapat mengakibatkan terbentuknya alur pada perkerasan aspal. Tabel nilai faktor koreksi modulus campuran beraspal hanya sebatas suhu perkerasan aspal sebesar 38OC sampai 42OC, sedangkan di wilayah Provinsi Riau cenderung memiliki suhu udara yang tinggi sehingga diperlukan pemeriksaan suhu perkerasan aspal yang terjadi di Provinsi Riau. Hasil penelitian ini menunjukkan bahwa suhu temperatur perkerasan aspal yang berada di Provinsi Riau melebihi dari suhu yang telah ditetapkan, dimana di Provinsi Riau didapatkan suhu maksimum perkerasan aspalnya sebesar 54.90OC dan suhu perkerasan aspal rata-ratanya sebesar 47.27OC, sehingga dilakukan penghitungan untuk menentukan nilai faktor koresi modulus campuran beraspal yang hasilnya untuk suhu maksimum sebesar 0.329 dan suhu rata-rata sebesar 0.606.

Abstract

This study compares the effects of peat water and normal water as mixing and curing water on the properties of crumb rubber and rice husk ash concrete (CR-RHA). The number of crumb rubber and rice husk ash used on the concrete followed the optimum mixture from a previous study, which was 5% and 10%, respectively. The crumb rubber was treated to overcome the lack of adhesion by soaking it in water for 24 hours. Normal concrete (PCC) was also cast as a control. CR-RHA and PCC concrete were mixed and cured using normal and peat water. Compressive strength, tensile strength, and porosity were tested at 3, 7, 14, 28, and 56 days. In general, CR-RHA concrete and PCC concrete showed lower performance when mixed and cured with peat water compared to normal water. Peat water with high acidity decreased the calcium content and developed the amount of pores in concrete, resulting in strength reduction. However, due to the excess pozzolan from rice husk ash, CR-RHA concrete had better resistance as the strength loss was relatively smaller, respectively 11.4% at 28 days and 10.6% at 56 days. Furthermore, CR-RHA concrete showed lower porosity, higher compressive strength, and tensile strength than PCC concrete due to rice husk ash that improved concrete density by generating CSH and crumb rubber that prevented concrete from spalling in an acidic environment. It was also found that compared to the previous study, pre-treated crumb rubber exhibited better mechanical and durability of concrete.

Abstract

Liquefaction is the transformation of soil into a liquid. The vibrating table in this study moves in a horizontal direction and the opposite manner in a vertical direction utilizing modelling. Acceleration variations of 0.25 g and 0.32 g were employed. The dirt was 10 centimetres thick. The sand clusters were 15 cm thick, with differences in debris gradient size and water surface on the sample. The uniform load that was employed was 40 kg/m2. Examine the drop of the ground surface and the rising of the porous water for signs of liquefaction. A 0.5mm diameter glass pipe was used to measure the porous water pressure. The test findings revealed that with higher acceleration, effective vertical voltage, and porous water ratio values, the rate of particle graduation has a major influence on the occurrence of liquefaction potential. The test results revealed that poorly graduated fine sand experienced maximum effective vertical stress and elevated porous water ratio values (Ru), whereas well-graded sand tended to be more stable.

Abstract

Kubang Jaya village is located in a low land peat swampy area and often suffers from the flood in the rainy season.  Swampy peat area generally has a high groundwater level; thus, it can immerse the septic tank in the housing in the area.  The height of the groundwater table is approximately 50cm from the surface level, while the depth of the septic tank is 150cm.  When the septic tank below groundwater level, this could cause a mix of soil water and septic tank waste.  This community development activity aims to educate the community about sanitation and give lecture and training of installing bio-porta septic tank (bacterial portable septic tank) for housing in high groundwater level area. Bio-porta septic tank consists of two drums as sediment tank and aeration tank. Bio balls were used to speed up the decomposition by aerobic bacteria in the tank.  An aerator was added to the installation to increase the proliferation of bacteria. The community development activities were pre-test, lecture, post-test, practical and cadre training.  Results show that there was an increase of understanding and knowledge of community from 24% to 62% about the septic tank in high groundwater level area.  The community also agreed to replace the conventional septic tank into the bio-porta septic tank in the future.  The activity also has a positive impact on educating and changing the mindset and attitude the community of Kubang Jaya village in improving the sanitation with an intention to the bio-porta septic tank in the future.BAHASA INDONESIA ABSTRACT: Desa Kubang Jaya merupakan kawasan dataran rendah rawa gambut dan sering mengalami banjir saat musim hujan. Lahan rawa gambut umumnya memiliki muka air tanah tinggi sehingga dapat merendam tangki septik pada perumahan yang terdapat di kawasan tesebut. Rata-rata tinggi muka air tanah sekitar ±50 cm, sedangkan kedalaman tangki septik warga sekitar ±150 cm dari permukaan tanah. Apabila tangki septik terendam, maka hal ini dapat mengakibatkan pencampuran air tanah dengan limbah tangki septik. Oleh karena itu dilakukan kegiatan pengabdian masyarakat dengan memberikan pengetahuan mengenai sanitasi lingkungan dan memberikan penyuluhan serta pelatihan pembuatan tangki septik bio-porta (bacterial portable septic tank) untuk rumah di lingkungan dengan muka air tanah tinggi. Tangki septik bio-porta terdiri dari dua drum yang berfungsi sebagai tangki pengendapan dan tangki aerasi. Untuk mempercepat proses penguraian oleh bakteri aerob di dalam tangki maka digunakan bio ball atau rumah bakteri. Aerator ditambahkan pada instalasi untuk mempercepat perkembangbiakan bakteri aerob. Kegiatan pengabdian terdiri dari pre-test, penyuluhan, post-test, praktek, dan pelatihan kader. Hasil evaluasi kegiatan pengabdian menunjukkan terjadinya peningkatan pengetahuan masyarakat dari 24% menjadi 62% tentang tangki septik di lahan dengan muka air tanah tinggi.  Masyarakat juga sangat setuju untuk mengganti tangki septik konvensional dengan tangki septik bio-porta di masa mendatang. Hasil kegiatan sangat berdampak positif untuk mengedukasi dan mengubah pola pikir serta sikap warga desa Kubang Jaya dalam memperbaiki sanitasi lingkungan tempat tinggal dengan keinginan untuk menggunakan tangki septik bio-porta di masa mendatang.

Abstract

Peatlands have an important role in ecosystems as a carbon storage and helps to reduce greenhouse gas emissions.Inappropriate peatland conversion causes common problems such as forest fires which create severe air pollution and trigger the production of greenhouse gases due to the release of stored carbon. As a result, early education regarding peat soil conservation is necessary to ensure that people understand the importance of peat soil and the harm that happens when peatlands are converted inappropriately. This program aims to educate students about peatlands and raise awareness about the importance of protecting and conserving peat from an early age. Educational materials are delivered using creative books containing illustrated stories, important knowledge about peat, and interactive games to attract student’s interest in reading and make information easier to recall. The results of the final evaluation through a questionnaire revealed that using creative books to educate students about peatlands was successful in improving students' understanding of peatlands. This is proven by the increasing number of students who fully understand the peat information that has been taught from 3 students to 32 out of 33 students.BAHASA INDONESIA ABSTRAK: Salah satu peran penting lahan gambut bagi ekosistem adalah sebagai pengikat karbon sehingga bermanfaat dalam mengurangi gas rumah kaca. Pengalihfungsian lahan gambut dengan cara yang tidak benar menyebabkan timbulnya masalah yang umum terjadi seperti kebakaran lahan gambut yang menyebabkan pencemaran udara melalui polusi kabut asap dan memicu terbentuknya gas rumah kaca akibat pelepasan karbon yang disimpannya. Untuk itu, pemberian edukasi mengenai pelestarian tanah gambut perlu diterapkan sejak dini agar masyarakat mengetahui peranan penting tanah gambut dan kerusakan yang terjadi apabila lahan gambut dialihfungsikan. Pengabdian ini bertujuan untuk memberikan edukasi pengenalan lahan gambut sekaligus meningkatkan kepedulian untuk menjaga dan melestarikan gambut sejak dini. Materi edukasi disampaikan menggunakan buku kreatif yang berisi cerita bergambar, pengetahuan penting tentang gambut, dan games interaktif agar menarik minat membaca dan membuat informasi menjadi lebih mudah diingat oleh siswa. Hasil evaluasi akhir melalui kuisoner menunjukkan bahwa pemberian edukasi tentang tanah gambut menggunakan media buku kreatif berhasil meningkatkan pemahaman siswa mengenai lahan gambut yang dibuktikan dengan bertambahnya jumlah siswa yang telah paham sepenuhnya mengenai materi gambut yang telah diajarkan dari semula 3 siswa menjadi 32 dari 33 siswa.
