Abstract

This paper discusses the results of the study, conducted to determine the effect of variations in cement content of the waiting time of curing (curing time) after the mixing process with a ground. Soils studied were from Jalan Simpang Loskala Pertamina Lhokseumawe. Portland cement used is the type of Andalas, with mixtures of two kinds of variation is 3% and 5%, a waiting period of 1 day, 3 day and 7 days. Physical properties of the test results, according to AASHTO; land into group A, 2-6, while according to the USCS; the land is included in group SC (sandy clay), visual observation as well, so the soil is sandy silt soil type, so it is non-cohesive and did not have a value of plasticity. Based on laboratory testing showed that the addition of the percentage of cement can increase the bearing capacity of the soil as well as the duration of curing.Keywords: cement content, bearing capacity, duration of curing

Abstract

Penjadwalan proyek konstruksi yang memiliki volume besar, tetapi sdikit item kegiatan, dimana kegiatan-kegiatan tersebut selalu berulang, penjadwalannya lebih cocok digunakan metode garis kesetimbangan, yang disebut juga metode Line of Balance ( LoB ) . Perencanaan penjadwalan proyek konstruksi mengandung unsur ketidakpastian yang sangat tinggi pada saat realisasi, pada umumnya akan terjadi perubahan-perubahan penjadwalan saat pelaksanaan. Dengan demikian, metode garis kesetimbangan ( metode LoB ) dapat digunakan untuk menyelesaikan masalah menyangkut perubahan-perubahan yang terjadi pada saat pelaksanaan proyek konstruksi tersebut. Beberapa cara untuk melakukan penjadwalan ulang dengan metode LoB, dimana dapat dilakukan sesuai dengan kasus perubahan yang terjadi.Kata-kata kunci: line of balance, project scheduling, penjadwalan ulang

Abstract

Settlement resilience in Klungkung Regency faces significant challenges due to rapid housing growth (8.2% per year) that is not balanced by adequate infrastructure, facilities, and utilities (Prasarana, Sarana, dan Utilitas [PSU]). These challenges are further compounded by the absence of local regulations governing PSU handover. This qualitative study employed an embedded case study design. Data were collected through in-depth interviews with 12 key informants, including government officials, developers, village heads, customary leaders, and banjar heads, as well as through field observations using a checklist based on Government Regulation No. 12/2021 and document analysis. Data analysis utilized the interactive model of Miles, Huberman, and Saldaña, incorporating regulatory analysis, the Disaster Risk Reduction (DRR) framework, and SWOT analysis. The findings indicate that PSU conditions remain far below national standards: 75% of housing estates have damaged roads, 75% experience clogged drainage systems, 100% lack green open spaces, and 100% have PSU assets that have not yet been formally handed over. In addition, one housing estate has been abandoned due to an inactive developer. Normatively, the Rancangan Peraturan Daerah (Ranperda) aligns with national regulations and incorporates three local innovations: recognition of customary villages (Article 13), provisions regarding abandoned PSU (Article 14), and spatial planning synchronization based on Tri Angga. However, implementation still faces three major gaps: limited supervisory capacity (with a ratio of 1:15.7), low community participation (only 20% of residents understand PSU obligations), and the absence of an inventory system for abandoned PSU assets. Local wisdom values derived from Tri Hita Karana and the banjar system demonstrate strong potential to strengthen PSU management through the ngayah tradition for routine maintenance. This study integrates three frameworks—regulatory analysis, DRR, and local wisdom—and provides empirical evidence regarding the operationalization of Tri Hita Karana in PSU management.
