Abstract

This paper investigates the relationship between economic growth and CO2 emissions from 1994 to 2018 using a panel approach from eight ASEAN countries. We found an established result using the Panel ARDL Pooled Mean Group method. First, the panel Cointegration analysis shows a significant long-term relationship between GDP and CO2 emissions. Second, the error correction mechanism shows a stable and consistent value. Third, we found that GDP has a significant long-term effect on CO2 emissions in ASEAN countries. Fourth, our results also show that GDP significantly impacts CO2 emissions in the short term for four countries: Indonesia, Malaysia, Thailand, and Cambodia. Based on these empirical results, implications and policy recommendations are presented. ASEAN countries should implement green growth policies by encouraging economic development which does not suppress the environment.

Abstract

Wasps in the family of Vespidae often have a yellowish black color with white or brown markings, but some species have variations in their markings and coloring. There is limited information available about the distribution of these marking patterns within the Vespidae Family. To clarify their taxonomic status, this study aims to examine the marking patterns of Vespid wasps that are widely distributed in the Indonesian Archipelago and to explore correlations with their biogeographical distribution patterns. In this study, specimens from three different locations (Bandung, Sumedang, and Purworejo) and specimens from the Museum Zoologicum Bogoriense (MZB) were examined. A total of 31 individuals from five different species were analyzed based on their morphological features. The data collected was coded and analyzed using cladistic methods, and the results were used to create cladogram trees for each of the five species i.e., Phimenes flavopictus, Polistes stigma, Apodynerus troglodytes, Vespa affinis, and Vespa velutina, showing their biogeographical distribution. The cladistic analysis in this study showed the relationships between the different species based on their morphological characteristics. The arrangements of the clades were determined using the Euclidean method in R studio. The results showed that P. flavopictus has two clades based on the marking patterns on their thorax and abdomen, while the other species i.e., Po. stigma, V. affinis, V. velutina, and A. troglodytes have three clades based on their coloring and marking patterns on all segments. The distribution of the Vespidae species appears to be scattered, with their patterns randomly distributed among locations.

Abstract

Handling stunting is part of the human resource development strategy to produce a superior generation. These efforts include specific nutrition interventions and sensitive nutrition, which in their implementation require support from all parties, including the village government. Handling stunting in this village is inseparable from how the policy is implemented. The purpose of this study is to analyze the implementation of stunting management policies in Tamansari Village, Kecamatan Jatinegara, Kabupaten Tegal and determine the supporting and inhibiting factors. The results of the study shows that the stunting management policy in Tamansari Village is still in progress. This means that problems related to coordination, funding and participation from village government officials and other relevant stakeholders are still the main problems. The Desa Tamansari Government has only accommodated the policy for handling stunting toddler in the APBDes after the issuance of the Decree of the Tamansari Village Head Number 5 of 2022 concerning the Establishment of the Tamansari Village stunting acceleration team (TPPS). Specific nutrition interventions for health programs for the target group of pregnant women, breastfeeding mothers, newborns, and infants under the age of two have basically been implemented for a long time through posyandu activities coordinated by village midwives, posyandu cadres, and family planning extension cadres. However, these activities are not in the context of handling stunting toddlers, but regular health service activities with the Health Office as the leading sector. In sensitive nutrition interventions, there is no intensive coordination between the village government and the social environment. Supporting factors for the handling of stunting in Tamansari Village include the support of the village government, the economic level of the target group not including poor families, so that the nutritional intake needs of children and mothers can actually be fulfilled independently and good social environmental conditions strengthen community participation in sensitive nutrition interventions and nutrition interventions. specifically in the management of stunting. The main inhibiting factor lies in the lack of communication and knowledge from the village government and residents regarding stunting and the impact of stunting, followed by inadequate budget support for handling stunting toddlers.

Abstract

Vespa affinis is a hornet with wide geographical distribution, occurring across the Indonesian Archipelago (Sumatra, Java, Kalimantan, Sulawesi, the Moluccas, and Papua) but excluding the Lesser Sunda Islands. Species with wide distribution typically show morphological variations that may differ across their range. This study aims to provide a detailed description of island-to-island diversity in morphometric characters and marking patterns among Indonesian populations of V. affinis. A total of 18 morphometric characters and 18 color patterns were analyzed. Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) were employed to distinguish variations in morphometric data. Marking pattern data were analyzed using the hierarchical clustering, to understand the clustering and relationship of marking patterns. The morphometric similarity recorded across the Indonesian archipelago suggests limited morphometric divergence among the populations. The marking patterns of V. affinis showed considerable variation across its geographical range, with brighter coloration in populations from eastern Indonesia compared to those from Sundaland.

Abstract

The problem we often encounter in the field of geotechnics, especially in Indonesia, is soft soil. The characteristic of soft soil is low bearing capacity. During the dredging process of the harbor basin, the soft soil in the harbor may experience movement. Therefore, a system is needed to retain the soil on the land side of the port in the form of sheet piles. However, the safety factor does not meet the requirements. Therefore, soil improvement is necessary to maintain soil stability by increasing the soil's shear strength, one of the methods that can be used is Cement Deep Mixing (CDM). This research aims to determine the required ratio of the area to be repaired. The analysis was conducted using the finite element method (FEM) with PLAXIS 2D. The research results show a CDM Improvement Ratio of 50%, a width of 20 m, and a depth of 35 m. The reinforcement includes Steel Pipe Sheet Pile (SPSP) with a diameter of 711.2 mm, a thickness of 16 mm, and a depth of 37 m, as well as Spun Pile anchors with a diameter of 800 mm, a thickness of 120 mm, and a depth of 20 m, with a distance of 2.2 m between each anchor and a distance of 15.76 m from the sheet pile. The modeling data used is the CDM soil improvement data from the Benoa Harbor Dredging Project, Indonesia.

Abstract

Rukoh Reservoir is located in the upper part of Krueng (Kr.) Rukoh River Watershed, Pidie Regency, Aceh Province with a catchment area of 19.63 Km2. This reservoir has a storage capacity of 124.42 million m3 and is used for irrigation, drinking water and hydropower. The condition of Kr. Rukoh there is no discharge recording device, so to obtain discharge data it is necessary to convert rainfall data into discharge in the form of Rainfall-Runoff Model.  The purpose of this research is to calculate the amount of flow discharge and the suitability of the two rainfall-runoff models using the F.J. Mock method and NRECA method with observed discharge. Furthermore, determining the amount of reliable discharge as inflow availability of Rukoh reservoir. This research begins with the collection of rainfall data, evapotranspiration and condition parameters of the Rukoh Reservoir catchment area. The parameters in both models are optimized to obtain the optimal model discharge that is close to the observed  discharge data (Qobs). The results of the model suitability test showed that the NRECA model discharge is better compared to the F.J. Mock discharge model, the NSE test value = 0.64 and the correlation test value R = 0.83. Based on the selected discharge model, the calculation obtained the average flow discharge as Rukoh reservoir inflow of 1.13 m3 / sec and 80% water availability of Rukoh Reservoir by 0.58 m3/sec and 90% water availability obtained at 0.43 m3/sec.
