As a result, it's crucial to reach net-zero carbon emissions. By balancing the total quantity of carbon dioxide or other greenhouse gas emissions over a specific period and taking actions that are ecologically responsible, net zero carbon emissions can be accomplished. For environmental sustainability to be successful, it must be able to influence people's attitudes and behavior toward the environment. To understand NGOs' obligations in supporting net-zero carbon emissions, this paper presents a methodical debate utilizing NGOs as case studies. The method is employed in this work by reviewing the body of primary and secondary research on the study issue. This essay initially lists different environmental NGOs organizations before categorizing and outlining some of the significant GHGs reduction initiatives made by these organizations. This essay also addresses key issues that must be addressed upon to achieve the best outcomes.

This study aims to understand the distribution of sand grains along the coastal zone of southern Lombok through sand grain analysis to support coastal management. Sand samples (n=60) were collected during June-July 2023 from ten different locations along the southern coast of Lombok, including both the intertidal and supratidal zones. The collected samples were dried and sieved to classify their size as Gravel, Very Coarse Sand, Coarse Sand, Medium Sand, Fine Sand, or Silt. Permutational Multivariate Analysis of Variance on transformed log-ratio data confirms that the sand composition in the intertidal zone is significantly different from the supratidal zone in all locations except Bumbang Beach, concluding the dominance of coarser materials in the intertidal zone and finer materials in the supratidal zone. The dominance of coarser materials is found in the southward-facing beaches, which are directly exposed to strong waves, while finer-grained sand is mostly found in covered coastal areas. Most of the coarser materials along Lombok’s southern coastline are composed of well-rounded carbonate sand formed from a large foraminifers, mixed with coral and shell fragments. Extreme dominance of the finer grain class can be found on Selong Belanak and Ekas beaches, indicating a susceptibility to abrasion.","PeriodicalId":31582,"journal":{"name":"International Journal of Marine Engineering Innovation and Research","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136345081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accidents result from human factors, vessel damage, management, and natural causes. Vessel stability is a significant concern, with WoD leading to increased load and rising KG, potentially causing capsizing. This study examines a RoPax OCD UFP that experienced a WoD-related accident in Indonesian waters. Modifications considered are standard freeing ports, becoming RoPax OCD SFP, and applying side casings, or RoPax OCD WS assessed the Stockholm Agreement. Fluid simulation and stability failure criteria were employed at varying wave heights. The largest RAO on the variation of heading angle is changed into stability criteria, resulting in realistic outcomes that have not been seen in earlier research. The highest RAO roll occurs at a heading encounter angle of 60 degrees with a value of 2.192362 degrees/m. Results show survival for RoPax UFP, RoPax SFP, and RoPax WS in the 0-1 m wave height range, with only RoPax UFP capsizing at 2-3 m. RoPax WS has an extended stability arm but decreases stability at high wave heights. RoPax SFP is unaffected by WoD but may still face capsizing depending on the pure stability arm GZ factor. Modifying RoPax UFP to RoPax SFP or RoPax WS can improve survival intact stability.","PeriodicalId":31582,"journal":{"name":"International Journal of Marine Engineering Innovation and Research","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136100514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shifting or overturning of the vehicle to the side of the ro-ro ferry has a big hand in causing the ship to capsize, and eventually an accident occurs. This study aims to determine the characteristics of the lateral and vertical acceleration of vehicles based on their location on the car deck under the influence of side waves. The method used is strip theory with the help of Maxurf software, which adheres to the B-spiline mathematical equation. The results of the study detected that vehicle positioning on the ro-ro ferry car deck significantly affects the value of vertical acceleration and lateral acceleration due to rolling motion. This is one of the parameters that can cause a vehicle to roll over.","PeriodicalId":31582,"journal":{"name":"International Journal of Marine Engineering Innovation and Research","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136100515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the management of ecotourism objects is not optimal, sometimes this makes ecotourism not much visited on weekdays or on weekends. This has an impact on ecotourism activities that are not really felt by local people who depend on these ecotourism activities. The research was carried out from June to August 2023. The research used an exploratory qualitative approach. The data used uses primary data obtained through interviews with various elements and measurements of water quality and water ecology. Meanwhile, secondary data was collected from various related document sources. Data analysis was carried out using Willingness to Pay (WTP), Willingness to Accept (WTA), economic potential analysis, SWOT analysis, Reliability test and Validity test. The results of the study indicate that the development strategy can be pursued by adding supporting facilities such as providing information boards for tourists regarding directions, location of supporting facilities and the furthest water point that is safe for swimming. The addition of environmentally friendly play facilities is also highly anticipated by tourists. Creative local economic products that can be developed are Kepek Gadapang and Turtle Themed Crafts.

Balikpapan City is also known as a port city because it has two domestic ports namely Kampung Baru Port and Semayang Port. Currently, the port of Kampung Baru is still active in carrying out daily activities, namely the klotok boat crossing and also the dock for motor boats berths. The condition of mobility for crossing vessels in the port of Kampung Baru that uses boat klotok is inadequate due to the lack of supporting components for access to the ship so the safety of this port is questioned. besides that, klotok ships are also only able to carry a maximum of 21 passengers and 5 motorcycles and access to loading and unloading exits is very unsafe. The purpose of this study is to design a crossing ship that can be used safely for transportation for passengers and motorcycles that will pass the sea lane for crossing to the North Penajam Paser area. The ship is designed to have an easy access door or ramp door for passenger and motorcycle mobility to improve the safety of crossings at the port of Kampung Baru. The parent Design Approach method is used in this project, this method is one way of designing a ship using comparison or comparison, namely by taking a ship that is used as a reference for a comparison ship that has the same characteristics as designed ship. The main focus to be achieved in this research obtained a General Arrangement which has more cargo than the klotok ship with a capacity of 25 passengers and 10 motorcycles, and the dimension of the ramp door used in this final project is L 1.50 m and B 1.50 m.
