Abstract

This article aims to formulate the embodiment of the AUPB concept in the standardization and geocoding system of Indonesian urban and rural addresses. Furthermore, it analyses the synchronization of data security principles in standardization and geocoding systems for urban and rural addresses in Indonesia. Conceptually, the process of address standardization and geocoding in the context of AUPB is closely related to the orderly administration of government, accountability of government agencies and/or officials, and implementation of statutory provisions. Overall, the element of AUPB that plays the most role in the standardization process and the address geocoding system is the principle of legal certainty. The principle of openness is attached to data security, and both are synchronized in implementing standardization and geocoding systems for urban and rural addresses in Indonesia. Even though all columns in the address database are stored in Elasticsearch, only specific columns can be accessed by general users through the Geocoding System website. Hence, the addresses presented are general data and do not contain personal data.

Abstract

Inappropriate land use can result in changes in environmental conditions that have negative impacts on humans. Land use that is not in accordance with its capabilities can cause various disasters, such as excessive erosion, landslides, floods, droughts, and an increase in the area of critical land. The Riam Kanan sub-watershed is one of the sub-watersheds in Banjar Regency, South Kalimantan whose condition requires conservation because this area has varying slopes, so if the land is not managed properly, it can cause flooding and other natural disasters. Based on this, it is necessary to carry out research related to the Land Use Capability Classification. The aim of this research is to analyze inhibiting or limiting factors and to formulate land use capability classes. The highest slope percentage of 15 - 25% is found in Land Unit 3 (three) Block A, Land Unit 4 (four) Block B and Land Unit 2 (two) in Block D. The lowest slope percentage of 3-8% is found in Unit Land 1 (one) Block A, Land Unit 1 (one) Block B and Land Unit 3 (three) in Block C. Other Land Units have a slope percentage of 8-15%. Land Use Capability Classes (KPL) obtained from the analysis results are 3 (three) Land Use Capability Classes (KPL), namely 1). KPL II with Soil Depth Limiting Factor "s". 2). KPL III with limiting factors for slope, soil depth and erosion. 3). KPL IV with Erosion Limiting Factor "e".

Abstract

The policy of working from home has bloomed since the global COVID-19 pandemic. New challenges arise when working from home where employees as individuals find it difficult to find the right balance between work and personal life (work-life balance). The influencing factors are excessive workload related to working hours, well-being, and social support related to psychological safety. This study examined the relationship between perceptions of working hours and psychological safety with the work-life balance of employees of private companies who work from home. This study involved 259 participants aged 20-53 years who are private employees who are working from home for at least two weeks. The results show that the perception of working time reduces work-life balance significantly, while psychological safety increases work-life balance significantly

Abstract

Landslide susceptibility mapping (LSM) produces a zonation map of landslide susceptibility levels, representing the future probability of landslides. It is necessary to give a guideline regarding spatial planning. A machine learning method was used, namely a random forest (RF) algorithm to map landslide susceptibility in Python. The case study is Palu City and its surrounding areas, which were attacked by a big earthquake on September 28th, 2018. Some earlier LSM studies did not discuss hyperparameter tuning, and several others did not mention the training accuracy. Therefore, this study is to find out whether the fast model without hyperparameter tuning and frequently overfitting, can well produce landslide susceptibility maps. The research questions were addressed by comparing two landslide susceptibility maps built with and without hyperparameter tuning using receiver operating characteristics (ROC) and landslide density (LD) analyses. This study shows that the area under the curve (AUC) of the landslide susceptibility map from the fast RF model without hyperparameter tuning is as high as the AUC from the tuned model map. It also happened in both landslide density (LD) maps, and there is no anomaly in the fast model map. Nevertheless, there are strange appearances in the fast model map. Therefore, hyperparameter tuning to obtain the optimal model with no overfitting is mandatory to predict landslide susceptibility spatially.

Abstract

Leadership is crucial element in the pursuit of organizational objectives. The examination of the characteristics of a proficient leader remains a compelling area of research, given its perceived capability to address diverse challenges, particularly those related to the organizational systems and human resources. This research used a convergent parallel mix-method to reveal type and profile of organizational management style that are effectively applied in business organizations in Indonesia today. Quantitative results revealed that the majority of managers in Indonesia apply a basic leadership separation (separated) style because of the lack of task orientation and relationships, which when affective produce a managerial style bereaucrate and when ineffective apply a deserter style. Temporary results qualitatively showed that at least four dimensions assessed must be owned by one person's leader: capacity to think strategically (strategic thinking), skilled management of tasks (task management), professional, and capable manage people or teams (people management). Integration results found convergent data because there are suitability dimensions between quantitative data and qualitative data related to management tasks and human management. Furthermore, it also obtained the results of the expansion from qualitative data was the emergence of the theme of strategic and professional thinking as a dimension that must be possessed by an effective leader in business organizations. Implications obtained based on the integration of quantitative and qualitative data analysis are perceptions that the profile ideal and effective leader can differ from what an individual applies inside the organization. As a result, even if the manager recognizes what capacities a leader should have, in practice, he may apply different styles and approaches.

Abstract

Kejadian aliran bahan rombakan di Kota Batu, Jawa Timur melanda 3 (tiga) kecamatan di wilayah Kota Batu pada hari Kamis, 4 November 2021. Kejadian tersebut berada pada aliran anak Sungai Brantas di lereng selatan Kompleks Gunungapi Arjuno Welirang. Bencana aliran bahan rombakan yang melanda wilayah Kota Batu dikontrol oleh luapan air akibat peningkatan volume air saat curah hujan tinggi dan adanya pembendungan di bagian hulu dari material bahan rombakan berupa kayu, bongkah batu dan material longsoran. Penyelidikan lapangan dan pemodelan numerik menjadi pendekatan yang signifikan dalam studi aliran bahan rombakan. Pemodelan dilakukan dengan perangkat lunak Rapid Mass Movement Simulation (RAMMS). Input data RAMMS meliputi data Digital Elevation Model (DEM), volume, daerah inisiasi, densitas, kohesi, serta parameter gesekan μ (Mu) dan ξ (xi). Berdasarkan hasil pemodelan dan analisis RAMMS menunjukkan bahwa parameter gesekan dan resolusi DEM sangat berpengaruh. Hasil model aliran bahan rombakan untuk μ : 0.04 dan xi : 500 secara umum mendekati dengan landaan aliran bahan rombakan 2021 dengan panjang landaan 4.85 km dan luas 238622.83 m2. Nilai parameter gesekan hasil pemodelan dapat dimanfaatkan untuk simulasi aliran bahan rombakan lain di kawasan selatan G. Arjuno Welirang untuk mengetahui potensi ancaman bahaya aliran bahan rombakan khususnya di wilayah Kota Batu, Jawa Timur.Kata kunci: aliran bahan rombakan, Kota Batu, pemodelan, RAMMSABSTRACTThe debris flow disaster in Batu City, East Java hit 3 (three) sub-districts in the Batu City area on Thursday, November 4th, 2021. The debris flow occurred in a tributary of the Brantas River on the southern slope of the Arjuno Welirang Volcano Complex. The debris flow was controlled by water overflow due to increased water volume during high rainfall and dams upstream of the debris material consisting of wood, boulders, and landslide material. Field investigations and numerical modeling have become significant approaches in debris flow studies. Modeling was carried out using Rapid Mass Movement Simulation (RAMMS) software. RAMMS data input includes Digital Elevation Model (DEM) data, volume, initiation area, density, cohesion, as well as friction parameters μ (Mu) and ξ (xi). The results of RAMMS modeling and analysis, show that the friction parameters and DEM resolution are very influential. The results of the debris flow model for μ: 0.04 and xi: 500 are generally close to the 2021 debris flow with a maximum distance of 4.85 km and an area of 238622.83 m2. The friction parameter values resulting from modeling can be used to simulate the flow of other debris in the southern area of Mt. Arjuno Welirang to determine the potential threat of debris flow, especially in the Batu City area, East Jawa in the future.Keywords: debris flow, Kota Batu, modeling, RAMMS
