The area and distance between buildings at POLINELA Campus make the presence of adequate connector roads an important necessity to support the mobility of the academic community. This study aims to optimize the scheduling of flexible pavement construction for the POLINELA Connector Road using the Critical Path Method (CPM) based on Microsoft Project 2021. The research method used is descriptive quantitative by processing the Budget Plan (RAB) data into a project schedule consisting of 11 main activities. CPM analysis is used to determine the sequence of work, dependencies between activities, the critical path, and project completion time. The results show that the total project duration is 23 calendar days (May 11–June 6, 2026). CPM analysis identified 10 activities on the critical path with zero float, while embankment work is a non-critical activity with time flexibility. Applying a Start-to-Start (SS) relationship with a 3-day lag between excavation and embankment work allows parallel implementation, reducing the project duration by 4 days (14.8%) compared to the conventional Finish-to-Start (FS) scenario. These results indicate that implementing CPM through Microsoft Project 2021 can increase execution time efficiency, simplify schedule control, and support decision-making in road construction project management.

Mining roads play an important role in supporting the smooth running of mining activities, especially in the process of transporting materials. The bearing capacity of the soil as a road subgrade greatly affects the stability and resistance of the road to heavy equipment loads. This study aims to analyze the effect of the plasticity index and compaction parameters on the California Bearing Ratio (CBR) value, as well as to determine the thickness of the road layer based on the laboratory CBR value. Testing was carried out at the South Pit of PT. Bina Sarana Sukses site PT. Baramulti Suksessarana with a field test method using the Dynamic Cone Penetrometer (DCP) and laboratory tests such as proctor tests, Atterberg limit tests, and CBR tests on various variations of clay and sand soil mixtures. The results showed that increasing the plasticity index decreased the CBR value, while increasing the maximum dry density and decreasing the optimum water content increased the CBR value. Based on the laboratory CBR value, recommendations were obtained for the appropriate road layer thickness to ensure optimal bearing capacity for heavy equipment passing through the research area.

Sludge is a by-product of an activity that comes from the discharge outlet of the flocculation, sedimentation and backwash filtration basins. To determine the volume of sludge contained in one liter of raw water, it is necessary to conduct a Jartest Test by determining the optimum dose of PAC. This water sampling was carried out at the Krian 1 Water Treatment Plant (IPA). Primary data collection is obtained from Imhoff Cone Results data. While for secondary data collection we get from Jartest data.  The manufacture of the coagulant solution used is Poly Aluminum Chloride (PAC). The average turbidity value in February was around 123 NTU and there was an increase in turbidity on the seventh day which reached 237 NTU. The drastic increase in turbidity reached 455 NTU with an average turbidity in March of 130 NTU. The graph shows that there is a significant correlation between the volume of sludge produced during the treatment process and the level of water turbidity. Thus, the researcher suggests further treatment of the remaining sludge which can be done by making a Sludge Drying Bed (SDB).
