Abstract

Kegiatan Kuliah Kerja Nyata (KKN) merupakan bentuk implementasi Tri Dharma Perguruan Tinggi, khususnya dalam bidang pengabdian kepada masyarakat. Artikel ini bertujuan mendeskripsikan program penanaman pohon sebagai upaya konservasi lingkungan di SMP Negeri 12 Bandar Lampung dan Kelurahan Rawa Laut. Metode pelaksanaan menggunakan pendekatan partisipatif melalui koordinasi dengan pihak sekolah, kelurahan, dan masyarakat. Sebanyak 50 bibit pohon ditanam, terdiri atas 25 bibit di lingkungan sekolah dan 25 bibit di wilayah pemukiman warga. Hasil kegiatan menunjukkan manfaat ganda, yaitu peningkatan kualitas lingkungan melalui penambahan ruang hijau serta peningkatan kesadaran masyarakat dan siswa tentang pentingnya pelestarian lingkungan. Meskipun terdapat kendala berupa keterbatasan lahan, kondisi tanah yang keras, dan ketersediaan air, hambatan tersebut dapat diatasi melalui kerja sama dan gotong royong. Dengan demikian, program ini memberikan kontribusi nyata terhadap konservasi lingkungan sekaligus membentuk karakter peduli lingkungan pada mahasiswa dan masyarakat

Abstract

The foamed mortar (morbus) lightweight material consists of a mixture of sand, cement, water, and liquid foam (foam agent), which can improve the mechanical properties of clay soil and increase its bearing capacity. This research uses various variations of superplasticizer mixtures, namely by adding additional ingredients in the form of sikament-LN which will increase compressive strength by up to 40% at 28 days. This research needs to be carried out to determine the effect of sikament-LN on increasing the compressive strength of foamed mortar. The percentages of the sikament-LN mixture were 0.5%, 0.75%, 1%, and 1.25% with ages of 7, 14, and 28 days, each of which made 3 test objects in 4 variations of the mixture. The research results showed that the addition of sikament-LN to the 1.25% mixture did not meet the requirements because it produced a flowability of 23.5 cm and the mixture experienced a shrinkage of > 20% when placed in a cylindrical mold. All foamed mortar specimens experienced an average dry density increase of 1.994% at a curing age of 7 to 14 days and an average dry density increase of 4.044% at a curing age of 7 to 28 days. In a mixture of 0.5%, 0.75%, and 1%, at 28 days the maximum compressive strength value obtained was 841,667 kPa (more than the required 800 kPa). For the sikament-LN mixture, a maximum of 1% of the cement weight is recommended so that the hardening process occurs in the foamed mortar test object.
