global warming and environmental issues are being caused by the overuse of fossil fuels and increased industrialization around the world, which has resulted in the production of greenhouse gases. 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 report gives a broad overview of the synergizing domains that NGOs around the globe work in to assist improvement environmental security .

Beyond its tourist appeal, beach sand plays a significant role in various dimensions, including ecological and geological aspects. 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.

RoPax vessels are widely used worldwide but contribute to numerous fatalities. 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.

Ferry accidents in Indonesia happen not just once or twice, but more than that. This is reinforced by statistical data on shipping transportation accidents. 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.

Gili Noko Island is one of the islands located in the Bawean archipelago, Gresik regency. The beauty of the beaches and underwater scenery on this island often captivates tourists but access to this island is quite limited. This research proposes the design of a tourist boat concept with a glass bottom route from Bawean to Gili Noko. In this research, there were several research design used those were the principal dimension, lines plan, general arrangement, construction calculation, stability analysis, ship motion analysis, and ship comfort. The selection of the engine is based on the calculated power required for the boat's resistance. The chosen engine is an electric propulsion system as a new environmentally friendly alternative. From the technical analysis, the boat's dimensions are found to be Loa: 11.83 m, B: 4.50 m, B1: 0.80 m, H: 1.50 m, T: 0.60 m, Cb: 0.611, and Vs: 7 knots. The engine power is 10.5 HP, and the battery capacity is 840 Ah. The construction calculation reveals that the boat weigths 4.8584 tons. The stability analysis complies with IMO standards, and the motion analysis and ship comfort meet the criteria set by Olson in 1987 .

As a popular tourist attraction, the Binasi Beach ecotourism area is always busy receiving visits from domestic and foreign tourists when the holiday season arrives. 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. Furthermore, the government can issue policies to provide routine guidance and access to capital for businesses run by local communities.

Ship repair is a project that is short in process so that time is an important element in its completion parameters. Delay is something that can happen to a job. A job experiencing delays must have a cause that affects the work. Causes of delay in the case of ship repair are poor time management, less skilled human resources, the addition or development of work. But whatever the obstacles, shipyards are still required to complete the ship repair process in a timely manner. Seeing this problem, this research was conducted to provide input in connection with the strategies used by PT XYZ in overcoming the delay factor in the repair of the KM Binaiya ship. In the research to support this thesis, the Bayesian Networks Method is used to analyze the factors that cause delays in ship repairs. After risk identification using the Bayesian networks method. The highest risk is replete activities as minor categorized, where the caused tank cleaning work related to hazardous waste, which must be cleaned to be safe for hot work with a risk score of 0.108. The second cause is installation of scaffolding for replete work facilities at height with a risk score of 0.054.

Balikpapan City has an area of 508.9 km2 which has 646,727 people living here. 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. The Principal dimension of the ship obtained in this research is Loa = 12.50 m, Lpp = 11.50 m, Lwl = 11.96 m, B = 5.75 m, B1 = 1.64 m, H = 1.8 m, T = 0.85 m, Cb = 0.56, Vs = 15 Knots. The results of this study provide a good idea of the modernization of a comfortable ferry fleet for this area.
巴厘巴盘市面积508.9平方公里，有646727人居住在这里。巴厘巴盘市也被称为港口城市，因为它有两个国内港口，即甘榜巴鲁港和三阳港。目前，甘榜巴鲁港仍在积极开展日常活动，即克洛托克船过境，也是摩托艇泊位的码头。在甘pung Baru港使用船klotok的过境船只的机动性条件不足，因为缺乏进入船只的支持部件，因此该港口的安全性受到质疑。此外，klotok船最多只能搭载21名乘客和5辆摩托车，进出装卸出口非常不安全。本研究的目的是设计一艘可以安全用于乘客和摩托车运输的过境船，该过境船将通过海上通道穿越到北Penajam Paser地区。该船设计有一个容易进入的门或斜坡门，用于乘客和摩托车的机动性，以提高甘榜巴鲁港过境点的安全性。本项目采用的是parent Design Approach方法，该方法是一种采用比较或比较的方法来设计船舶，即以一艘被用作参考的船舶作为与被设计船舶具有相同特征的比较船。在这项研究中要实现的主要重点是获得了一个总体安排，它比可容纳25名乘客和10辆摩托车的klotok船装载更多的货物，并且在这个最终项目中使用的坡道门的尺寸为L 1.50 m和B 1.50 m。本研究得到的船舶主尺寸为Loa = 12.50 m, Lpp = 11.50 m, Lwl = 11.96 m, B = 5.75 m, B1 = 1.64 m, H = 1.8 m, T = 0.85 m, Cb = 0.56, v = 15节。本研究的结果为该地区舒适渡轮船队的现代化提供了一个很好的想法。

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. The Principal dimension of the ship obtained in this research is Loa = 12.50 m, Lpp = 11.50 m, Lwl = 11.96 m, B = 5.75 m, B1 = 1.64 m, H = 1.8 m, T = 0.85 m, Cb = 0.56, Vs = 15 Knots.

Bathymetric surveys nowadays are often used by the echosounding method. This method has weakness because the range that can be surveyed is limited due to cannot reach areas that have shallow depths. With advances in technology, there are alternative ways that can be done to map the depth of the sea, with the help of satellite imagery or remote sensing. This method uses a mathematical algorithm based on a combination of spectrum channels called Satellite-Derived Bathymetry (SDB). In this research, Sentinel-2 satellite imagery was used with Lyzenga algorithm. Lyzenga (2006) uses multilinear regression which is a combination of an equation that aims to convert pixel values into in-situ depth values. Within research of six locations in Bali Province, which are Sangsit Harbor, Gunaksa Harbor, Amed Port, Keramas Beach, Serangan Harbor and Sawangan Beach produced an R 2 value each of 0.451, 0.747, 0.495, 0.610, 0.451 and 0.676. While the RMSE values were 26,247, 12,377, 31,942, 3,531, 3,000, and 1,992 respectively for water depths of 146 m, 97 m, 183 m, 22 m, 13 m, and 18 m respectively. The parameters that affect the level of accuracy are: water depth, presence of breaking waves, presence of disturbance objects in the waters.
