Abstract: The development of an area must consider the sustainability of the region based on the economic, social and environmental factors. Kota Baru Lampung as a future development center for the central government of Lampung Province really needs to be developed as an environmentally friendly region. Green lane road is part of the landscape in the right of way area (r.o.w) which has the function of safety and comfort to road users, supporting educational activities, recreation and conservation, aesthetics and identity of the area as well as forming the character of a city. The function of plants on the road landscape is to reduce exposure to direct sunlight and vehicle lights, as a guide, physical barriers, controlling movement, controlling microclimate, and animal habitat. This study aims to evaluate the right of way area (r.o.w) as a green road from aesthetic, comfort and safety functions, designing right of way (r.o.w) in accordance with regulations with attention to the principles of sustainable road development. Based on evaluation results, there are several things which stems from interpretations of the information (data) resulted from the evaluation, which are: 1.) The development of a new area must adhere to the principles of sustainable road development so that the negative impacts from the development of an area can be minimized. 2.) The condition of right of way (r.o.w) and the planning of the Kota Baru master plan need to be evaluated to meet environmental standards that are required to have a minimum of 20% open green space (RTH), by applying the principles of environmentally sound road development. 3.) The design concept of right of way that has an environmental insight, should be implemented and promoted in every development of an area.

In general, infrastructure development requires materials from nature and one of them is natural coarse aggregate of crushed stone. The rapid development of infrastructure in Indonesia has resulted in the depletion of the natural coarse aggregate. Therefore, other efforts are needed in terms of using coarse aggregate as a construction material. So in this study the aim is to make artificial coarse aggregate made from fly ash. The results showed that this artificial coarse aggregate met the requirements of the General Specifications of Bina Marga 2010 rev 3 as a construction material, namely for an abrasion value of 40% and water absorption of 3%. In this study, 5 types of comparisons were carried out, namely, 70:30%, 60:40%, 50:50%, 40:60%, 30:70 and for the type of composition comparison 70:30% (70% fly ash:30% cement). ) the abrasion value is still below 40%, and the amount of water absorption is below 3% so that this artificial coarse aggregate still meets the standard specifications of General Highways 2010 rev 3. Based on the price comparison that has been made between artificial coarse aggregate and natural coarse aggregate of crushed stone , shows a price disparity of Rp. 35,779 - Rp. 58,779. Thus, this artificial coarse aggregate is one solution that can be developed to reduce the environmental impact due to the presence of fly ash which is quite abundant in Indonesia.

This study evaluates the influence of vertical geometric variation on the seismic response and inter-story drift of reinforced concrete Special Moment Resisting Frame (SMRF) buildings located in the high seismic zone of Bandar Lampung. Three hypothetical 30-meter-tall models were analyzed: Model A (12 stories), Model B (10 stories), and Model C (8 stories). Nonlinear static pushover analysis was performed in accordance with SNI 1726:2019 and ATC-40 criteria. The results indicate that variations in story height significantly affect the dynamic characteristics and deformation patterns of the structures. Model A exhibits the shortest natural period (T = 1.559 s) and the largest base shear capacity (8,722 kN), but shows more limited post-yield behavior due to the short column effect. Model C produces the highest drift ratio (1.072%) as a result of the more dominant P-Delta effect. All models achieve the Life Safety (LS) performance level, with the majority of plastic hinges remaining in the Immediate Occupancy (IO) category, indicating available deformation capacity. Within the scope of this study, Model B is considered the most balanced configuration in terms of stiffness, drift, and ductility, and is therefore recommended as a balanced vertical geometric configuration for 30-meter-high buildings.
