Abstract

The development of information technology brings a change in society. Social media is a technological sophistication-based media classified from various forms, such as magazines, internet forums, weblogs, social blogs, microblogging, wikis, broadcasts, photos or images, videos, ratings and social bookmarking. Social media has several impacts on life, namely positive impacts and negative impacts. This community service activity was carried out on June 15, 2021 and is located in the Selaki Beach Tataan Building Village. The method in this research is descriptive qualitative. The purpose of this community service activity is to improve the community's economy through social media, introduce tourist attractions, and introduce handicrafts in the Selaki Beach Tataan Building Village. This study concluded that in the coastal area, Selaki requires a cellphone or still has limited signal and only certain sim cards can still be accessed, while those who have children only have sophisticated cellphones to attend online schools.

Abstract

Lake Tirta Gangga is an artificial lake located in Central Lampung Regency, Seputih Banyak District, precisely in Swastika Buana Village. This lake has an area of ​​about 150 hectares and is used by the community for irrigation of about 3000 ha of agricultural land around the area. Lake Tirta Gangga has its own charm for local tourists to enjoy its natural beauty and scenery. However, some community activities cause the aspect of natural beauty to be reduced and cause problems in the supply of raw water for agriculture. So we need an action that can maintain the initial function of this lake and even add economic value to the community. This service aims to overcome these problems by mapping the potential of new geotourism that can be developed and managed by the community, educating the community in improving the quality and excellence / local wisdom which has an impact on increasing the economic value of the Tirta Gangga Lake area by utilizing information technology for media promotion (with drones) profile of the Lake Tirta Gangga tourist area. The benefits of this service are the mapping of new geotourism potentials that can be developed and managed by the community as well as the formation of video promotion media for the profile of the Lake Tirta Gangga tourist area which can be disseminated through internet media so that tourists can easily recognize and be interested in visit Tirta Gangga Lake.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan menerapkan teknologi tepat guna berbasis pemanfaatan abu sekam padi sebagai pengganti sebagian semen dalam pembuatan paving block di Desa Sendang Mulyo, Kabupaten Lampung Tengah. Permasalahan utama yang dihadapi masyarakat adalah belum optimalnya pengelolaan limbah sekam padi serta tingginya ketergantungan terhadap semen sebagai bahan konstruksi utama. Metode yang digunakan adalah pelatihan dan pendampingan teknis yang meliputi sosialisasi, praktik pembakaran sekam padi secara terkendali, pencampuran material, dan pencetakan paving block dengan substitusi abu sekam padi sebesar 10% dari berat semen. Evaluasi dan monitoring dilakukan melalui observasi langsung, diskusi dengan peserta, serta analisis situasi pascapelatihan. Hasil pengabdian menunjukkan bahwa masyarakat mampu mengaplikasikan teknologi tersebut secara mandiri tanpa kendala teknis berarti. Temuan ilmiah menunjukkan adanya perubahan persepsi masyarakat terhadap limbah sekam padi menjadi sumber daya bernilai guna, potensi pengurangan penggunaan semen, serta peluang efisiensi biaya produksi paving block. Kegiatan ini juga meningkatkan pengetahuan dan keterampilan masyarakat dalam mendukung pembangunan infrastruktur desa yang ramah lingkungan dan berkelanjutan.

Abstract

Keterbatasan ketersediaan air merupakan permasalahan utama pada lahan pertanian tadah hujan yang berdampak pada rendahnya produktivitas dan kesejahteraan petani. Kondisi ini juga dialami oleh masyarakat Desa Munjuk Sempurna, Kecamatan Kalianda, Kabupaten Lampung Selatan, yang sebagian besar menggantungkan mata pencaharian pada sektor pertanian namun belum didukung oleh infrastruktur irigasi yang memadai. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberdayakan masyarakat desa melalui pembangunan sumur bor dan sistem irigasi pipa sebagai solusi penyediaan air bagi lahan pertanian tadah hujan. Metode pelaksanaan kegiatan dilakukan dengan pendekatan partisipatif, meliputi survei lapangan, kajian teknis hidrogeologi, perencanaan dan pembangunan sumur bor, pemasangan sistem irigasi pipa, serta sosialisasi dan pelatihan pengoperasian kepada masyarakat. Hasil kegiatan menunjukkan bahwa sumur bor yang dibangun mampu menyediakan pasokan air yang relatif stabil dan sistem irigasi pipa dapat mendistribusikan air secara merata ke lahan pertanian. Selain menghasilkan luaran fisik berupa infrastruktur air, kegiatan ini juga meningkatkan pengetahuan dan kapasitas masyarakat dalam mengelola sumber daya air secara mandiri. Dengan demikian, pembangunan sumur bor dan sistem irigasi pipa berbasis pemberdayaan masyarakat terbukti efektif dalam mendukung peningkatan produktivitas pertanian tadah hujan dan berpotensi meningkatkan kesejahteraan masyarakat desa.

Abstract

This study examines the effect of utilizing fly ash waste as the main raw material in the production of polymer bricks on the mechanical and physical properties of the resulting material. This research employed an experimental laboratory method by producing fly ash-based polymer brick specimens activated using alkaline solutions of NaOH and Na₂SiO₃. The curing temperatures applied in this study were 70°C, 80°C, and 90°C. The tests conducted included compressive strength tests and water absorption tests. The results showed that the utilization of fly ash as the primary material significantly influences the increase in compressive strength of polymer bricks. The highest compressive strength value was obtained at higher curing temperatures, indicating that an increase in curing temperature accelerates the geopolymerization process and produces a denser and stronger material structure. In addition, the water absorption test results indicated that the polymer bricks have relatively low water absorption values, which reflects low porosity and good material quality. Therefore, fly ash-based polymer bricks have strong potential as an environmentally friendly alternative building material, energy-efficient, and possessing good mechanical performance, making them a sustainable solution for industrial waste utilization
