Abstract

The construction of BTS towers to fulfill equitable communication requires analysis of structural construction calculations so the tower can be standing properly in locations that have low soil bearing capacity. This research aims to analyze the design of the BTS tower sub-structure to withstand in structural loads, wind, overturning, and uplift forces so the tower can be standing properly. To achieve the research objectives, studies and analyses were conducted through literature study, load analysis, structural modeling through software analysis and interaction diagrams, evaluation of soil bearing capacity, and verification of applicable construction standards in Indonesia. The analysis shows the dead load of the sub-structure, the overturning moment of 6.539 x 10³ kN.m in the X direction and 5.352 x 10³ kN.m in the Y direction meet the safety value of 1, thus ensuring stability according to SNI 8460: 2017. The maximum ground pressure is 97,808 kN/m², below the required 294,200 kN/m² at a depth of 1.4 m, with safety factors of soil bearing capacity (3.008), shear capacity (2.897), and shear strength (1.5) all meeting safety standards. The reinforcement analysis follows SNI 03: 2847-2019, specifying that D16-200 reinforcement is required for bottom and top with a ratio of 0.002 and 0.001. Torsional shear for axial (1,225 x 10³ kN.m) and compression (1,578 x 10³ kN.m) stress conditions, as well as ratios exceeding 1% ensure the safety of the support. Overall all structural elements meet the safety requirements, ensure the stability of the tower and comply with relevant standards.

Abstract

Research on the review of the form and aesthetics of Javanese script-style fonts can be crucial in developing better Javanese script fonts that align with user needs. Javanese script fonts are an important aspect of preserving Javanese script culture, and their usage is increasingly growing in the digital context. In this study, researchers can analyze the form of Javanese script fonts, such as letter characteristics, spacing, kerning, and proportions. Additionally, the study may involve assessing the aesthetics of Javanese script fonts, including font selection and overall design. This research also includes a study of the history and development of Javanese script fonts to gain a more contextual understanding of font design. The study employs qualitative methods, such as interviews with users of Javanese script fonts or visual analysis, and quantitative methods, such as surveys on Javanese script font preferences. The results of this study can provide significant benefits for the development of better Javanese script fonts that meet user needs and strengthen the cultural identity of the Javanese script. This research can also contribute significantly to the preservation and development of local culture.

Abstract

Akses logistik perikanan di Desa Malalanda terhambat oleh kondisi jalan tanah dan macadam yang rusak parah, menyebabkan tingginya biaya distribusi dan penurunan kualitas kesegaran ikan. Kapasitas perangkat desa dalam menyusun perencanaan teknis yang sesuai standar juga sangat minim, sehingga pembangunan sering kali gagal dini. Pengabdian ini menawarkan solusi melalui pendekatan Participatory Rural Appraisal (PRA) yang berfokus pada penyusunan dokumen teknis jalan perkerasan kaku (rigid pavement). Pelaksanaan kegiatan dibagi menjadi tiga tahap sistematis: persiapan (identifikasi masalah dan koordinasi), pelaksanaan (survei topografi, uji Dynamic Cone Penetrometer, dan perencanaan desain), serta evaluasi komprehensif. Hasil dari program ini mencakup serah terima dokumen Detailed Engineering Design (DED) jalan beton setebal 250 mm (mutu K-350) beserta Rencana Anggaran Biaya (RAB). Dampak konkret kegiatan ini ditunjukkan dengan peningkatan signifikan pemahaman teknis perangkat desa dan warga mengenai spesifikasi jalan standar, dari yang awalnya hanya 30% menjadi 75%. Dokumen teknis ini langsung digunakan sebagai landasan pengajuan infrastruktur dalam program Kampung Nelayan Merah Putih, memberikan kepastian infrastruktur jangka panjang bagi mitra.
