Abstract

This study will try to investigate variations in the angle of the Z-direction build part by using a 3D Printer with Fused Deposition Modeling (FDM) technology made from PLA + Sugoi. This study uses a 0.4mm nozzle with a Bowden type extruder. This study uses a PLA+ filament from the Sugoi brand with a nozzle of 0.4 mm, diameter filament 1,75 mm, 3D Printer with Fused Deposition Modeling (FDM) technology used is Creality Ender 3 V2 with process parameter settings in slicing software using a layer thickness of 0.30 mm, Top solid Layer 5, Bottom Solid Layer 5, Fill density 100%, cooling speed 100%, and flowrate 100%, nozzle temperature 205°C, and bed temperature 60°C. Variation in angle Part build Z-direction is proven to have a significant difference in Tensile strength with a difference of 10° resulting in a difference in Tensile strength of 15 MPa, where the highest tensile strength is 67.50 MPa with part build Z-direction at an angle of 80°, and the lowest tensile strength of 52.50 MPa with a Z-direction part build angle at an angle of 70°.

Abstract

The land conflict between the residents of Pengudang Village and PT Buana Megawisatama (BMW) in Bintan Regency dates back to 1993, whenthe company offered compensation to local residents to relinquish their land at disproportionately low prices, accompanied by promises ofresidential plots and housing, most of which were never fulfilled. This imbalance triggered mounting tensions and protests from the community, culminating in demonstrations involving university students and resulting in repressive actions by security forces. This study aims to examine the root causes of the conflict in depth and to evaluate the effectiveness of various resolution efforts undertaken, including mediation and directinterventions by relevant stakeholders. Data were collected through in-depth interviews with informants selected via snowball sampling. The findings reveal that this conflict reflects structural tensions between local communities and corporate interests over access to and control of land, with significant social, economic, and environmental repercussions for the affected population. Despite the local government’s mediation efforts and land retribution initiatives.
