Abstract

This study provides a detailed investigation of the material behavior of concrete-filled double-skin tubes (CFDST). The research primarily focuses on the development and examination of cross-sectional variations, stress-strain relationships in the materials, and their corresponding characteristics. By conducting a comprehensive study and evaluation, this research endeavors to provide a more profound comprehension of the impact of this particular behavior on the overall responsiveness and capacity of materials. The influence of various parameters on a variety of cross-sectional configurations, comprising circular outer and circular inner tubes (C-C), circular outer – square inner tubes (C-S), square outer – circular inner tubes (S-C), square outer – square inner tubes (S-S) have been recently examined in earlier research. Furthermore, this study discusses additional evaluations consisting of sandwiched concrete and the inner and outer steel components. Despite the substantial study conducted by CFDST, there is presently a lack of established guidelines or regulations pertaining to the design of composite structures. Consequently, it is imperative to acquire a comprehensive comprehension of the behavior exhibited by these materials. This understanding serves as essential for the development of design rules specific to CFDST composite structures. By performing consequently, the outcomes of this study can be effectively employed in the design, analysis, and optimization of the distinctive attributes associated with composite materials.

Abstract

The Department of Food Security and Agriculture (DKPP) of Bojonegoro District is a government agency at the district level that focuses on food security and agriculture. The main objective of this department is to enhance the production of food crops, horticulture, and plantations through the improvement of human resources and agricultural infrastructure. DKPP Bojonegoro has undertaken various initiatives to improve the quality and quantity of agricultural products. One of these initiatives involves deploying extension officers to provide guidance and support to farmers in the field, both those formally affiliated with Farmer Groups (POKTAN) and individual farmers. In practice, each extension officer is assigned to a district or the area of a farmer group that requires assistance, with assignments subject to change and flexibility based on the needs of DKPP Bojonegoro. However, the challenge lies in DKPP's difficulty in ensuring that the extension officers are effectively carrying out their duties in the field. The monitoring function performed so far relies solely on reports submitted by the extension officers, a method that may lack validity in verifying whether the officers are performing their tasks well in the field. In response to this issue, the proposed solution in this research is a Location-Based Monitoring System for agricultural extension officers. The goal is to facilitate DKPP in monitoring the presence of extension officers in designated areas and to automatically manage attendance when assigning officers to a farmer group or district.

Abstract

Security protection for content providers is essential in a digital content distribution system so that only authorized users can access the content. However, focusing on the security aspect often makes the system ignore the privacy of content users. This article presents a model of protocol that can provide balanced protection of content provider security and user privacy in a digital content distribution system. This protocol is based on oblivious transfer (OT), a standard protocol in cryptography that allows the sender of a message to send a certain amount of information securely to the recipient of the message, such that at the end of the protocol the recipient of the message cannot access more information than specified, while the sender of the message cannot know which information was successfully accessed by the recipient. Assuming the existence of tamper-proof devices, the protocol presented in this article can provide excellent protection for both the security of content providers and the privacy of content users.

Abstract

This study aims to acquire photogrammetric data for the purpose of generating a slope map of Kedungsari Village. Aerial imagery was captured using a drone flown at a specific altitude with optimal overlap and sidelap settings. To enhance positional accuracy, ground control points (GCP) were established and surveyed using the static method of Geodetic GPS. The data processing workflow involved photo alignment, georeferencing, dense point cloud generation, point cloud classification, digital elevation model (DEM) creation, and orthomosaic generation. The slope map was derived from a Digital Terrain Model (DTM), which was classified into several categories based on slope gradient. The resulting map is expected to serve as a reference for landslide susceptibility analysis and land-use planning
