ASDP Indonesia Ferry Company (PT. ASDP) is a state-owned company that transports water in seas, lakes, and rivers. In vessel operations, the ASDP requires more energy. Consequently, the more energy supplied, the more emission results. In addition, ASDP is potentially harmful in polluting sea water, lakes, and rivers because if passengers are not aware of throwing garbage as long as they are on board, they will pollute the water. Based on the Indonesian provision, the country should reduce carbon emissions by 27% without supporting overseas institutions, and 41% by supporting donors. This requires strict effort because the country needs more energy to grow economically, while the country has to reduce consumption. Another strategy is required to maintain growth. It appears from individual awareness that they work in the ASDP. They do initiatives in terms of reducing CO2 emissions and pollution. This study aimed to explore how ASDP workers are aware of reducing CO2 emissions and greenhouse gases by reducing their causes. This study used in-depth interviews to obtain information about how to build awareness among them and how they plan green ASDP. Through their initiative, they arranged the green ASDP Plan. It consists of green management, ports, and shipping. They developed a roadmap green ASDP over 10 years. Every year, they make targets that are proofed by certificates related to any greens, such as ISO 14001, ISO 5000, greenship certificate, etc.

We introduce a comparative study of two surgical kits for the lateral approach of maxillary sinus lifting using a conventional Dentium Advanced Sinus Kit (DASK) system versus a Sinus Lateral Approach (SLA) trephine bur. This study aims to clinically and radiographically evaluate and compare the effectiveness of using a conventional DASK system versus an SLA trephine bur in the lateral window approach of sinus lifting with simultaneous implant placement. The clinical study was conducted in 2023 on twenty patients indicated for open sinus lifting procedures. Patients were divided into two groups: the conventional group was treated using DASK trephine bur group was treated using the Sinus Lateral Kit (SLK). Radiographic Assessment included measurements of changes in bone heights and bone gains formed buccally and palatally around the implant on cross-sectional cuts of cone beam computed tomography (CBCT), incidence of membrane perforation, and duration of surgery. Data were collected and statistically analyzed using IBM SPSS Statistics version 23 for Windows 10. The SLA trephine group showed a lower perforation rate and reduced surgical time than the conventional group, with statistical significance difference. A statistically non-significant difference was observed in implant stability and bone density between the two groups. Conclusion: The use of trephine drills in the SLA system allows better access to the lateral approach and minimizes the risk of sinus membrane perforation and operative time during osteotomy compared with conventional DASK drills.

Artificial juveniles are crucial for advancing commercial aquaculture in terms of their quality, quantity, and cost. The three key factors for successful aquaculture are egg, feed, and water. Eggs need to be healthy and genetically advanced to exhibit fast growth, superior meat yield, disease resistance, and early maturation. Premium traits were carefully selected and refined through generations (F1 and F2) to stabilize these desirable qualities for commercial applications. Consequently, hatcheries should prioritize the production of premium juveniles to meet growing demands. The aim of this study was to establish a fish seed production method capable of generating premium juveniles at low cost and with ease. The Semi-Intensive Seed Production (SISP) method is tailored for breeders, small investors, and fishermen, who may lack extensive knowledge or access to advanced technology required for intensive microalgae, rotifers, and Artemia cultivation. SISP selects ideal characters by natural selection during the seed production period, and the method can be applied to other species. Furthermore, the method accepted small investments to join aquaculture, which solved one of the bottlenecks of the business, and the method can be applied to other species. The SISP does not require a significant upfront investment or high operational expenses; instead, it requires a sizable tank (20 m3 and 2 m depth), water supply, agricultural fertilizer, an air blower, and artificial feeds. Rather than relying heavily on cultured rotifers and Artemia, SISP leverages wild-bloomed phytoplankton and zooplankton. Research conducted with various fish species in Chile and Cuba from 2010 to 2024 demonstrated that while SISP exhibited a lower survival rate (2%) compared to Intensive Seed Production (ISP) (70%), it offered cost-efficiency and superior quality advantages. Nonetheless, SISP encountered challenges in meeting the demand for mass production culture owing to its dependence on live feeds, which hinge on phytoplankton.

The use of video games and motion capture systems to maintain functional autonomy in older people is becoming increasingly significant, as they contribute to improving quality of life. The objective was to carry out a systematic review to identify the usefulness of serious video games in maintaining functional autonomy in older adults and to understand the technologies used for the analysis of their movements and the body parts that have been worked on in order to maintain functionality in the performance of their instrumental activities of daily living. The systematic review was based on the criteria proposed by the PRISMA method, and searches were carried out using the following databases: Scopus, PubMed, and IEEEXplore. In the basic search, criteria such as the use of video games, motion capture technologies, and functional autonomy in older adults were taken into account. The search was limited to open access publications published in the period 2015 to 2023, and 153 documents were analyzed, leaving 91; subsequently, 62 that did not meet the inclusion criteria were eliminated, ending with 30 articles that were directly related to the study topic. Among the findings, it was found that the creation of serious video games for older adults was aimed at multiple fields where commercial technologies prevail, which, due to their low cost, allows the interaction and implementation of gamified activities to improve the quality of life of older adults. Therefore, the work reported on the use of inertial measurement units was 12%, using the Microsoft Kinect sensor 70%, and other technologies 18%. All of these were used as motion capture systems. On the other hand, the two video games reported in the aforementioned articles showed that 20% were commercial products, whereas 80% were self-developed. The novelties that emerged through the analysis of research work were the report of a large number of studies, 70% of which focused on the objective of maintaining balance, coordination, strength, and psychophysiological postural parameters in the elderly, and the additional 30% corresponded closely to the field of physical rehabilitation. Additionally, the implementation of serious video games in older adults allows for active participation in physical activity, leaving aside conventional methods. Therefore, improvements are given from the creation of serious video games and application of mini-games, taking into account the individuality of each adult, as well as the needs, interests, and capacities, thereby achieving mental, emotional, and social balance.

In Vietnam, arbitration is a method of resolving disputes in commercial business, established on the principle of voluntariness and agreement of the parties, to anticipate conflicts that may arise or have arisen. Creating a solid legal corridor to protect the legitimate rights and interests of the parties based on equality and voluntariness between subjects participating in transactions and contracts related to commercial business to agree to resolve disputes by commercial arbitration is necessary to contribute to the effective implementation of foreign investment capital collection policies in Vietnam. Through qualitative research methods, the authors will focus on clarifying the legal situation and pointing out inadequacies in legal regulations in Vietnam related to issues such as (i) the effectiveness of arbitration agreements and (ii) the form of arbitration agreements. From there, we propose recommendations to improve the law in Vietnam related to commercial arbitration agreements.
Keywords: agreement; effect; form; commercial arbitration
