Artificial Intelligence: Analisis Praktik Robotic Journalism dalam Produksi Berita
Authors: Nurfiana Efen
Published: August 2024

Penggunaan artificial intelligence (AI) dalam bentuk robotic journalism pada industri media bukan fenomena baru, faktanya banyak industri media yang menggunakan artificial intelligence dalam produksi berita. Sampai di sini, setidaknya muncul pertanyaan dasar terkait apakah artificial intelligence pada konteks jurnalis, dapat dikatakan sebagai efisiensi atas perkembangan teknologi? Apakah robotic journalism berkemampuan menggantikan jurnalis manusia dalam praktik jurnalisme? Menyadari adanya kekhawatiran calon profesional bidang jurnalis, maka kajian ini berupaya menganalisis fenomena robotic journalism untuk mengetahui tantangan praktik penggunaan robotic journalism, dampak positif dan negatif. Kajian ini menggunakan metode deskriptif kualitatif. Kajian ini menemukan praktik robotic journalism menghasilkan jumlah dan kecepatan produksi berita yang jauh melampaui jurnalis manusia. Namun di sisi lain, robotic journalism mengacu pada algoritma hambar dan mekanis, karena robotic journalism tidak dapat menentukan kausalitas, mengajukan pertanyaan, membentuk opini, memiliki kemampuan menulis lebih rendah dari manusia, adanya indikasi plagiarisme, dan tidak memenuhi prinsip etika jurnalistik. Oleh karena itu, praktik robotic journalism tetap harus melibatkan kinerja jurnalis untuk mengevaluasi berita yang dihasilkan.

Published: August 2024

The addition of Bacillus Subtilis bacteria to the mud soil at IPAM (Integrated Wastewater Treatment Plant) Perumda Tirta Manuntung Km.8 in Balikpapan City aimed to enhance its suitability as a temporary cover layer in places like landfills. Initial mud testing revealed key characteristics: Chemical Characteristics: The mud's specific chemical composition was identified, providing a foundation for a deeper understanding of its properties. Physical Characteristics: The mud falls into the fine-grained soil category, with 63% of particles passing through a No. 200 sieve. Moisture content is high at 42.54%, primarily composed of silt (39.8%) and clay (25%). Mechanical Characteristics: Standard proctor tests yielded a maximum dry unit weight of 1.099 gr/cc and an optimum water content of 33.65%. Initial soil permeability met temporary landfill cover criteria, with a permeability value of 5.04×10-4 cm/s. Further research demonstrated that by introducing Bacillus Subtilis bacteria at varying concentrations and incubation periods, mud permeability could be altered. The highest permeability, 4.27×10-4 cm/s, was achieved with an 8% bacteria concentration and a 7-day incubation period, while the lowest permeability, 1.19×10-5 cm/s, resulted from an 8% bacteria concentration and a 28-day incubation period. These findings suggest that Bacillus Subtilis addition can modify mud permeability, making it more suitable as a temporary landfill cover. This presents a potential solution for more effective IPAM management.

Beaches often experience erosion or abrasion problems caused by various factors, such as climate change which triggers rising sea levels, high waves, human activities such as beach reclamation, and infrastructure construction that is not environmentally friendly, triggering erosion on the coast. In the coastal area of the city that supports IKN, which is located in the Balikpapan area, Manggar Beach, also experiences abrasion which causes land to narrow in that area. The abrasion that occurs erodes the coastal area around 7-8 meters every year. To produce environmentally friendly infrastructure, this research carried out the addition of coconut fiber waste components to tetrapod concrete used for breakwater construction. In this research, variations in the addition of coir used were 0%, 1%, 2%, 3%, 4% and 5%. The aim was to find out how much influence the addition of coconut coir waste to the concrete mixture had on the compressive strength, tensile strength and flexural strength of the concrete in tetrapods. and produce concrete that uses coconut fiber waste as an alternative material for tetrapod concrete as breakwater armor. Based on the analysis results, the quality of the concrete was 23 Mpa. This value was determined based on wave generation analysis. In addition, it is known that variations in coconut fiber affect the slump, compressive strength, flexural and split tensile test values of concrete. Based on the slump test results, it was found that the greater the variation of coconut fiber in the concrete, the lower the resulting slump test value. In testing the compressive, flexural and split tensile strength, it was found that the optimal composition for adding coconut fiber was 3%, in this composition the amount of coconut fiber fiber was able to improve the mechanical properties of tetrapod concrete compared to other compositions.

The increase in vehicle volume in Lampung Province has resulted in a decrease in road performance. Capacity evaluation is prevention, determining capacity there are several parameters, one of which is EMP. In this case, the analysis of road section performance refers to MKJI 1997. The characteristics of MKJI 1997 are strongly influenced by the traffic of major cities in Indonesia which are made the place of empirical research in 1991 - 1995. Of course, there are differences in the characteristics that occurred in that year with the current situation. This study was conducted to determine whether there is a difference in the EMP value in MKJI with the current field EMP. This research uses field survey data including traffic volume, road section geometry, and Time Headway data between vehicles. In this study, the emp value is analyzed using the Time Headway method and the data for analyzing the performance of road sections refers to the 1997 Indonesian Road Capacity Manual (MKJI). The results of the emp MC value for the morning and afternoon peak hours on Section 1 are 0.48 and 0.46. Section 2 is 0.46 and 0.44. This value is significantly different from the 1997 MKJI emp of 0.25. for the DS value using emp MKJI on section 1, the results are 0.45 and 0.68. for DS emp calculations on section 0,3 of 0,43 and 1. For section 2 DS emp MKJI of 0.33 and 0.48. For DS emp calculations on section 2 of 0,48 and 0,65. It can be seen that significant differences can be caused by traffic flow conditions, differences in road characteristics, road gemetry conditions, and environmental conditions in 1997 with current conditions. It can also be seen that the greater the emp value will affect the amount of traffic volume so as to make the degree of saturation value greater.

The development of information and communication technology is increasing every year, contruction sector indeed. The rapid increase in technology in the construction sector has forced all AEC actors in Indonesia to follow these developments as an effort to increase work productivity. The breakthrough that can support infrastructure development to follow the digitalization era is the use of various technologies and applications of Building Information Modeling (BIM) which have many benefits. However, for the implementation of BIM in Jambi City itself still relatively low, from the maturity level of BIM based on the model (Succar, 2010) obtained a value of 0.719 at the non-existence level, which means that the use of BIM in construction companies in Jambi City has not yet been implemented. the discovery of the potential use of BIM, even seen from the optimism of the implementation of BIM in the company, not all informants have high optimism. Therefore, a study was conducted on the inhibiting factors that hindered the implementation of BIM in construction companies in Jambi City, using interview techniques to determine the actual obstacles. The 5 highest barriers factors were identified, that is Lack of understanding of BIM and its benefits, Lack of government support, Requires high hardware specifications, High investment costs for BIM official licenses, Lack of market demand (Clients). With this research, it is hoped that the application of BIM can be better and provide maximum benefits to construction companies in Jambi City.

The bad drainage system in the road pavement area also causes the road body to be submerged in water for quite a long time, causing the bond between the asphalt and aggregate to loosen, resulting in decreased service life. Developments in the field of road construction have now implemented many innovative ideas, one of which is namely the use of rubber asphalt with asphalt containing natural rubber which has 1.5 to 2 times the strength compared to conventional asphalt. In evaluating the performance of an asphalt mixture, especially the AC-WC Wear layer mixture, it can be analyzed using the Marshall test method by taking into account the conditions being tested, namely the test object being immersion in water or continuously flooded with water. The method used in this research is an experiment with treatment conditions for AC-WC rubber asphalt mixture specimens which are continuously immersion in water for 1 day, 2 days and 3 days. The research results showed that there was an increase in the VMA, VIM, and flow parameters, while the VFB, stability, and Residual Strength Index parameters decreased with increasing soaking time. Based on the research results, it can be concluded that although there is an influence on the performance of the asphalt mixture with the use of rubber asphalt, the decrease that occurs is not too large and is still within the required specifications.

Padang State University has experienced rapid student enrollment growth, driving the need for new infrastructure. Most of the buildings have more than 3 floors, and one of the ongoing projects reaches a height of 32.05 meters with 6 floors, contributing to higher construction risks. This research was conducted to evaluate the implementation of Construction Safety Plans (CSP) on projects over the past two years in accordance with the Ministry of Public Works and Housing Regulation No. 10 of 2021 and the Circular Letter of the Ministry of Public Works and Housing No. 10 of 2022. Data collection methods for this study involved two approaches: compliance audits and performance audits. Compliance audits involved document-based inspections of CSP, while performance audits included on-site observations and project work evaluations. The research results revealed that the construction of the central information and library building achieved the highest CSP implementation rate, with compliance rates of 93.33% in compliance audits and 91.42% in performance audits. In contrast, the rehabilitation project for the Faculty of Sports Sciences and the Dean's office showed lower compliance rates, scoring 37.14% in compliance audits and 35.34% in performance audits. The study also found that project contract values correlated with CSP compliance levels. Higher contract values were associated with higher CSP compliance. Contractor qualifications also played a crucial role in ensuring compliance with safety regulations. Based on these findings, it is recommended that UNP exercise greater selectivity in contractor selection processes. This study highlights the importance of construction safety in construction projects.
