Abstract

Abstrak Desa Bomo memiliki potensi wisata pantai yang besar, khususnya di kawasan Pantai Ria Bomo. Namun, pengelolaannya masih menghadapi berbagai tantangan seperti penurunan kualitas lingkungan akibat sampah dan kerusakan vegetasi pantai serta kurangnya promosi dan branding digital untuk menjangkau wisatawan lebih luas. Kondisi ini berdampak pada minimnya kunjungan wisata dan rendahnya kontribusi ekonomi dari sektor pariwisata bagi masyarakat lokal. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan kapasitas dan kemandirian masyarakat dalam mengelola potensi wisata pantai secara berkelanjutan. Permasalahan utama yang dihadapi mitra meliputi kerusakan ekosistem pesisir serta kurangnya promosi wisata secara digital. Metode pelaksanaan kegiatan ini dilakukan dengan pendekatan partisipatif dan kolaboratif antara tim pengabdi, mitra selaku pengurus pokdarwis, masyarakat lokal, dan perangkat desa. Pendekatan ini melibatkan masyarakat sejak tahap perencanaan, pelaksanaan, hingga evaluasi. Melalui kegiatan ini, dilakukan penanaman pohon di kawasan pantai, sosialisasi pelestarian lingkungan dengan melibatkan warga lokal, serta pembuatan dan pelatihan website destinasi. Hasil kegiatan ini diharapkan dengan penanaman pohon memperkuat ekosistem pesisir, penyadaran lingkungan menumbuhkan rasa kepemilikan masyarakat terhadap pantai, dan website menjadi sarana promosi jangka panjang. Dampak keberlanjutan tercermin dari peningkatan kesadaran, perbaikan ekosistem, serta meningkatnya kunjungan wisatawan. Kata kunci: branding digital; pantai Ria Bomo; promosi wisata; revitalisasi ekosistem. Abstract Bomo Village has significant potential for beach tourism, particularly in the Ria Bomo Beach area. However, its management still faces several challenges such as declining environmental quality due to waste and coastal vegetation damage, as well as a lack of promotion and digital branding to reach a wider range of tourists. These conditions have resulted in low tourist visits and minimal economic contributions from the tourism sector to the local community. The community service activity aims to enhance the capacity and self-reliance of the community in sustainably managing coastal tourism potential. The main problems faced by the partners include coastal ecosystem degradation and the lack of digital tourism promotion. The implementation method of this program was carried out through a participatory and collaborative approach involving the service team, partners as Pokdarwis managers, local communities, and village officials. This approach engaged the community from the planning and implementation stages to the evaluation stage. The activities included tree planting along the coastal area, environmental conservation awareness programs involving local residents, as well as the development and training of a destination website. The outcomes expected from these activities are that tree planting will strengthen the coastal ecosystem, environmental awareness will foster a sense of ownership among the community toward the beach, and the website will serve as a long-term promotional tool. The sustainability impact is reflected in increased awareness, improved ecosystems, and the growth of tourist visits. Keywords: digital branding; Ria Bomo beach; tourism promotion; ecosystem revitalization.

Abstract

This paper presents a theory of optimal control of building structures that are experienced in the earthquake load excitation by using an active mass damper. Control mechanism is done using active mass exerts a force on the control structure based on structural response is continuously measured. The concept of the Linear Quadratic Regulator (LQR) is used to calculate the required control force structure based on the input acceleration response that is measured using the accelerometer. optimal control system reliability was tested using shear building model is given Active Tuned Mass Damper (ATMD) five stories above the structure to provide the base acceleration excitation of disturbances in the form of a data record from the accelerogram. Test results for various load acceleration theory base, such as acceleration simulation of El-Centro N-S earthquake, Kobe earthquake, earthquake Pacoima, Northridge earthquake, Kern-County earthquake, and the Chichi earthquake showed optimal control is able to give good results. From the analysis and simulation results concluded that the optimal weighting matrix on the value of Q=1000 and the weighting matrix R=0.1 are able to reduce on the structural displacement of the top floor ranged from 19.80% - 58.90%, while for the reduction of the displacement velocity structure in the top floor between 18.24% - 54.18%.

Abstract

Rainfall is an important weather parameter that significantly influences the agricultural sector and regional planning. The City of Mataram, as the center of social and economic activities in West Nusa Tenggara Province, requires an accurate rainfall prediction method. This study aims to predict daily rainfall in Mataram City using a multivariate long short-term memory (LSTM) approach. The data used consist of daily observations from BMKG, with input variables including average temperature, average humidity, average wind speed, and average air pressure. The dataset is structured as a time series using a sliding window approach with a 7-day lookback period and is divided into 80% training data and 20% testing data. The LSTM model is constructed with two LSTM layers containing 64 and 32 units, respectively, complemented by a 0,2 drop out layer and a Dense layer as the output for prediction. Evaluation using MAE and RMSE indicates that a configuration of 100 epochs and a batch size of 16 provides the best performance, achieving MAE of 4,020 mm and RMSE of 7,915 mm on the testing data, demonstrating the model’s capability to predict daily rainfall in a stable manner.

Abstract

The accuracy of reinforcement volume calculations is a critical factor in the success of construction projects, particularly for structural elements such as foundations, columns, and beams. In Indonesia, conventional calculation methods are still widely used, typically based on two-dimensional drawings from AutoCAD. However, with technological advancements, Building Information Modeling (BIM) methods have begun to be implemented, offering more precise three-dimensional modeling and better data integration throughout the planning and execution stages. This study compares the reinforcement volume of structural elements calculated using conventional methods and the BIM method through Autodesk Revit software in the Power House construction project at Ngudi Waluyo Regional Hospital, Wlingi, Blitar Regency. The results indicate that the Revit BIM method generally produces a higher reinforcement volume compared to the conventional method. For example, the foundation reinforcement volume using Revit was 616,846 kg, while the conventional method yielded 595,053 kg, showing a difference of 2,85%. Similar discrepancies were found in other elements, such as transverse and longitudinal tie beams 3,09%, columns 2,30%, beam B2 3,18%, beam B3 3,49%, beam B4 3,81%, slab A0 3,01%, and slab A1 1,09%.

Abstract

With the advancement of construction technology, precast methods such as half slab have begun to be implemented as alternatives to conventional methods in floor slab construction. This study aims to compare the floor slab construction costs between the half slab precast method and the conventional method in the construction project of the Ar Rahim Building, UIN Malang Phase II. The analysis focuses on reinforcement costs for slab types A1 and A2 on the 1st floor and roof using the conventional method, and on slab types A1 and A2 on the 2nd and 3rd floors using the half slab precast method. The research uses a quantitative approach by comparing costs based on work volume and unit prices of materials. Based on the calculations, it was found that the conventional method resulted in a lower reinforcement cost of Rp 3,323,263,608 compared to the half slab precast method, which required Rp 4,709,791,209—resulting in a higher cost difference of Rp 1,386,527,601. Although the half slab precast method requires a higher investment for reinforcement components, it offers advantages in terms of construction time efficiency and quality control. This study contributes to the selection of appropriate floor slab construction methods by considering cost aspects.
