Abstract

The construction process frequently necessitates the demolition of existing structures, resulting in substantialconstruction waste. A significant portion of this waste comprises demolition debris, particularly from concrete buildingmaterials. This research aims to develop standard concrete by partially substituting conventional coarse and fineaggregates with concrete waste materials. The substitutions involved replacing 25% and 50% of sand and gravel,respectively, by weight, using a K300 concrete mix design. Adopting the SNI 03-2834-2000 method, the mix design for 1cubic meter of concrete comprised cement (528 kg), sand (776.16 kg), gravel (807.04 kg), and water (205 kg). Theresults indicated an average sample weight reduction, with the first sample at 12.91 kg, the second at 12.79 kg, and thethird at 12.77 kg. This weight decrease suggests that using waste as a partial aggregate substitute impacts concretedensity. Compressive strength tests revealed a reduction of 5.98% in the concrete containing a 25% waste mixture, withaverage compressive strength declining from 307.22 kg/cm² to 288.94 kg/cm². A more pronounced reduction occurred inthe 50% waste mixture, where compressive strength decreased by 15.70% (from 307.22 kg/cm² to 259.06 kg/cm²). Thistrend aligns with the understanding that higher waste content correlates with greater mechanical strength reduction, likelydue to the differing physical properties of waste materials, such as lower density, which impact overall concreteperformance, particularly in compressive strength.

Abstract

Access roads at Politeknik Negeri Lampung (Polinela) support mobility for students, lecturers, and staff. Thequality of these roads, particularly the level of damage, is a serious concern as it disrupts accessibility for students and staff.Additionally, this condition hinders academic activities and the overall operations of the campus. Adequate and appropriaterepair efforts are necessary to ensure comfort and safety within the campus environment, thereby better supportingacademic activities.The Bina Marga Method is an approach used to assess the level of road damage. The assessment isconducted using specific established criteria, such as road classification and the severity of damage. The data collected isthen analyzed to determine the priority order for repairs and maintenance plans.The access road to Polinela Campus is 1,616.4 meters long and has an average daily traffic volume of 1,011.5 passengercar units per hour, classifying it into traffic class 4. Based on the results of the analysis, the condition rating of the PolinelaCampus road is 6, indicating that the priority order for road management is 7. Under these conditions, routine maintenanceis required. The routine maintenance needed in this case includes patching holes and resurfacing the pavement.

Abstract

ABSTRAK Banyak pekerja di Pekon Srikaton yang bergerak di bidang konstruksi belum mempunyai Sertifikat Tukang karena belum pernah mengikuti pelatihan resmi. Kondisi ini menyebabkan pekerja belum memiliki sertifikat yang dapat digunakan sebagai pengakuan atau bukti bahwa mereka telah memenuhi standar kompetensi kerja. Tujuan pelatihan Tukang Bangunan Gedung Jenjang I adalah memberikan pengakuan dan pembuktian bahwa pekerja konstruksi memiliki pengetahuan, keterampilan, serta sikap kerja sesuai standar kompetensi yang dipersyaratkan. Metode pelaksanaan Pengabdian Masyarakat dilakukan dengan membentuk tim panitia untuk membantu seluruh proses pelatihan. Hasil kegiatan menunjukkan bahwa pelaksanaan pelatihan dan sertifikasi berjalan dengan nyaman, lancar, dan tertib. Peserta pelatihan yang sehari-hari bekerja sebagai tenaga konstruksi di Pekon Srikaton memperoleh peningkatan pengetahuan, keterampilan, dan sikap kerja sehingga menjadi lebih kompeten sebagai Tukang Bangunan Gedung. Seluruh peserta berhasil mendapatkan Sertifikat Tukang Bangunan Gedung Jenjang I. Kata Kunci: Pelatihan, Pekerja Konstruksi, Kompetensi, Sertifikat Tukang ABSTRACT Many construction workers in Pekon Srikaton had not obtained a Craftsman Certificate because they had never participated in formal training. This condition resulted in workers lacking formal recognition of their competencies in accordance with the required work standards. This community service activity aimed to support the implementation of the Level I Building Construction Worker Training by equipping workers with validated knowledge, skills, and work attitudes in accordance with established competency standards. The implementation method involved establishing a committee team to support the training and certification process. The results showed that the training and certification activities were conducted smoothly and comfortably. Participants who worked as construction laborers in Pekon Srikaton gained improved knowledge, skills, and work attitudes, enabling them to become competent Building Construction Workers. All participants successfully obtained the Level I Building Construction Worker Certificate. Keywords: Training, Construction Workers, Competence, Craftsman Certificate.
