Abstract

The development of information technology brings a change in society. Social media is a technological sophistication-based media classified from various forms, such as magazines, internet forums, weblogs, social blogs, microblogging, wikis, broadcasts, photos or images, videos, ratings and social bookmarking. Social media has several impacts on life, namely positive impacts and negative impacts. This community service activity was carried out on June 15, 2021 and is located in the Selaki Beach Tataan Building Village. The method in this research is descriptive qualitative. The purpose of this community service activity is to improve the community's economy through social media, introduce tourist attractions, and introduce handicrafts in the Selaki Beach Tataan Building Village. This study concluded that in the coastal area, Selaki requires a cellphone or still has limited signal and only certain sim cards can still be accessed, while those who have children only have sophisticated cellphones to attend online schools.

Abstract

Lake Tirta Gangga is an artificial lake located in Central Lampung Regency, Seputih Banyak District, precisely in Swastika Buana Village. This lake has an area of ​​about 150 hectares and is used by the community for irrigation of about 3000 ha of agricultural land around the area. Lake Tirta Gangga has its own charm for local tourists to enjoy its natural beauty and scenery. However, some community activities cause the aspect of natural beauty to be reduced and cause problems in the supply of raw water for agriculture. So we need an action that can maintain the initial function of this lake and even add economic value to the community. This service aims to overcome these problems by mapping the potential of new geotourism that can be developed and managed by the community, educating the community in improving the quality and excellence / local wisdom which has an impact on increasing the economic value of the Tirta Gangga Lake area by utilizing information technology for media promotion (with drones) profile of the Lake Tirta Gangga tourist area. The benefits of this service are the mapping of new geotourism potentials that can be developed and managed by the community as well as the formation of video promotion media for the profile of the Lake Tirta Gangga tourist area which can be disseminated through internet media so that tourists can easily recognize and be interested in visit Tirta Gangga Lake.

Abstract

The dominance of the construction sector presents its own challenges, one of which is the risk of occupational accidents. This fact is evidenced by cases of work-related accidents in structural work at the Crystal Boulevard Shop House development project in Summarecon Bekasi. This situation is driven by the occurrence of unsafe actions and unsafe conditions during the implementation of work activities. This study aims to identify potential occupational accident risks, analyze the level of these risks, and assess risk control measures in structural work, including rebar installation, formwork, and concreting activities. The methods employed in this study are the Severity Index and Construction Safety Analysis. The results are 27 risk variables related to occupational accidents were identified in structural work, with 27% categorized as low risk and 73% as medium risk. The risk control analysis conducted refers to the hierarchy of controls based on ISO 45001:2018 standards. This approach provides systematic results by organizing controls according to priority order, include substitution, engineering controls, administrative controls, and the use of personal protective equipment (PPE). Abstrak Dominasi sektor konstruksi memunculkan tantangan tersendiri, salah satunya adalah risiko kecelakaan kerja. Fakta ini diperkuat oleh adanya kasus kecelakaan kerja pada pekerjaan struktur di proyek pembangunan Ruko Crystal Boulevard Summarecon Bekasi. Hal tersebut dipicu oleh adanya tindakan tidak aman dan kondisi tidak aman selama pelaksanaan pekerjaan. Penelitian ini bertujuan untuk mengidentifikasi potensi risiko kecelakaan kerja, menganalisis tingkat risiko dan menganalisis pengendalian risiko pada pekerjaan struktur yaitu pembesian, perancah, bekisting dan pengecoran. Metode yang digunakan yaitu Severity Index dan Construction Safety Analysis (CSA). Hasil penelitian menunjukkan bahwa terdapat 27 variabel risiko kecelakaan yang teridentifikasi pada pekerjaan struktur, diantaranya 27% risiko rendah (low) dan 73% risiko sedang (medium). Analisis pengendalian risiko yang dilakukan mengacu pada hierarki pengendalian berdasarkan standar ISO 45001:2018. Pendekatan ini memberikan hasil yang sistematis dengan menyusun pengendalian berdasarkan urutan prioritas, yaitu subtitusi, engineering control, administratif dan Alat Pelindung Diri (APD).

Abstract

The implementation of construction projects often faces delays that are difficult to avoid, as experienced in the construction of the City X Hospital Building, where there was a discrepancy between the initial plan and actual field implementation, resulting in a two-week delay in weekly progress. This study aims to analyze time and cost efficiency and compare the effectiveness of alternatives between extending working hours and adding labor using the Time Cost Trade Off method. This research is comparative, comparing the total cost and duration of the project for both acceleration alternatives. The total project cost under normal conditions was recorded at IDR 7,289,386,643.45 with a duration of 86 days until the completion of the third floor. The analysis shows that extending working hours by 1 to 4 hours resulted in costs of IDR 14,584,817,481; IDR 21,871,659,072; IDR 28,672,701,971; and IDR 34,564,808,294, with cost efficiency of –100.08%, –200.05%, –293.35%, and –374.18%, respectively. The project duration was reduced to 64, 50, 41, and 36 days, with time efficiency of 26%, 42%, 53%, and 58%. Meanwhile, the alternative of adding labor resulted in a total cost of IDR 13,660,989,499 with a cost efficiency of –87.41% and a project duration of 64 days (26% time efficiency). Based on these results, both extending working hours by one hour and adding labor showed the most efficient outcomes, but overall, adding labor was considered more optimal as it achieved the same acceleration with the lowest total cost.

Abstract

Shallot (Allium ascalonicum L.) is a high-value horticultural commodity with continuously increasing demand. The success of shallot cultivation, particularly for seed production, largely depends on the availability of high-quality seeds, which is influenced by fertilization practices. Nitrogen (N) plays an important role in plant growth and yield formation; however, inappropriate N application can reduce seed quality. This study aimed to evaluate the effects of different urea fertilizer doses on the growth, yield, and seed quality of shallots, as well as to determine the optimal and efficient urea dosage. The research was conducted in Nglipar District, Gunungkidul Regency, Special Region of Yogyakarta, from April to December 2025, using a Randomized Complete Block Design with four urea dose treatments, namely 0, 100, 150, and 200 kg/ha, each replicated six times. Observed parameters included vegetative growth, yield components, and the physical and chemical quality of bulbs. The results showed that increasing urea doses tended to enhance plant height and leaf number up to a certain level, but did not always have a significant effect at the maximum vegetative stage. A urea dose of 100 kg/ha produced the highest bulb weight, productivity, and the best physical and chemical bulb quality compared to higher doses. Application of urea above the optimal rate reduced yield and nitrogen use efficiency. Therefore, a urea dose of 100 kg/ha is recommended as the optimal rate to improve the quantity and quality of shallot seed.
