Abstract

Soil is the main support in a construction. Unstable soil conditions, especially in the subgrade can cause damage to the road. Based on the results of a direct survey in the field, it was found that the condition of the Jalan Kampung Keramat in Pangkalpinang City was damaged. This might be caused by the condition of the subgrade on the road which is unstable and the subgrade is categorised as clay soil type. This study aims to improve the subgrade on Jalan Kampung Keramat in Pangkalpinang City by using limestone as a soil stabilization material. This study used an experimental method in the laboratory by making mixture between clay soil and limestone with four different variations in the percentage of limestone, namely 0%, 3%, 5%, 7%. There are four parameters of the mixed characteristics that are tested and analysed, namely: the Atterberg limit, specific gravity, soil gradation and CBR value. The results show that the Atterberg limit values ​​(liquid limit-LL and plasticity index-IP) and specific gravity tend to decrease with increasing percentage of limestone extinguished. However, the plastic limit value (PL) shows the opposite tendency, i.e. it increases with the decreasing percentage of limestone. The specific gravity values ​​obtained based on the percentage of lime outages (0%, 3%, 5%, 7%) are 2.63, 2.61, 2.60, and 2.58, respectively. In addition, the addition of limestone causes changes in soil gradation, namely the addition of retained fraction # No.200 and the reduction of passed fraction # No.200. The Addition of limestone can increase the CBR value of the soil, where the addition of 7% of limestone produces the highest CBR value (21.3%) compared to 5% limestone (15.7%), 3% limestone (13.4%) and 0% limestone (11.2%). Therefore, using limestone can improve quality of subgrade, which can be seen from the value of CBR obtained.

Abstract

Study examines the paradox between the awards received by Bangka Regency at the local and national levels for stunting reduction and the actual condition in Mendo Barat District, which has continuously been designated as a stunting locus from 2019 to 2024. Research employs Michael Lipsky’s (1980) Street-Level Bureaucracy theory and uses a qualitative method with a case study approach conducted between 2020 and 2024.Findings indicate that the paradox arises because coordination among coordinators, field officers, and communities has not been fully aligned due to limited resources. These constraints trigger the emergence of discretionary practices and coping mechanisms. The main strategic error lies in the excessive focus on children already affected by stunting, rather than emphasizing preventive measures. Programs implemented tend to focus on short-term reduction efforts rather than holistic prevention. Consequently, this situation creates an imbalance between the recognition received by the government and the actual field conditions in Mendo Barat District. In addition, program implementation varies across the area, leading to different interpretations at the local level and reducing overall program effectiveness. The direction of policy implementation should not depend solely on the government or field officers, but also on the active role of the community. Community participation, particularly among families affected by stunting, remains passive limited to being program beneficiaries rather than active agents in addressing stunting issues. For example, the low adoption of the GERMAS principles in daily life such as hygiene behavior, healthy lifestyles, and dietary ethicsillustrates this challenge, as emphasized in PERBUP No. 56 of 2022.
