Abstract

The success of waste management must be connected to the community's participation. The community's involvement in waste management still needs to be significantly apparent. Community participation in rural waste management programs was investigated in this study since the waste reduction activities still involve open burning and burying of waste in the yard, which is harmful to the environment. A research model was designed, and a questionnaire was distributed among 112 households (HHs) to analyze their participation in rural waste management programs. A semi-structured questionnaire survey, focus group discussions, and key informant interviews were adopted to acquire qualitative information. The analytical framework includes mass balance analysis (MBA) and Arnstein's participation (APL) ladder. MBA was applied to measure each HH's current waste reduction rate, while (APL) was used to evaluate the community participation level in this program. The findings revealed that the average waste reduction is 0,48 kg/HH/day, contributing to a total waste reduction of 17.94 kg/day in the village (24.39% of total waste generation). Measurement using APL unfolds that the extant community participation in Mojosari Village, Bojonegoro Regency, corresponds to a non-participation continuum where villagers are simply misled by pseudo and tokenistic participation, leading to unequal benefit-sharing. Based on these findings, the researchers challenge that communities' engagement in rural waste management mainly relies on community cadres concerning environmental subjects as well as communities' economic backgrounds. It is concluded that where economically weak communities and manipulative figures exist, ensuring a higher community participation level is more challenging.

Abstract

Tanjung Buton Port is one of the ports with considerable potential to support national development. The water quality status in the Tanjung Buton Port area is suspected to be declining, water quality due to activities in the port area. So, this study aims to determine the status of water quality in the Tanjung Buton Port area based on the Sea Water Quality Index. The research was conducted in October - November 2023 in the Tanjung Buton Port Area in Sungai Apit Regency, Riau Province. Determination of water quality status uses the Marine Water Quality Index (WQI) method. This research will be conducted at three measurement and sampling stations, where one sampling will be done at each station. Measurements and sampling are carried out at low tide. Parameters observed include temperature, pH, DO, salinity, TSS, total ammonia, oil and grease, and ortho-phosphate.  The condition of Tanjung Buton Harbor water quality status in this study based on the Marine Water Quality Index (WQI) is included in the "moderately polluted" category with WQI ranging from 50.01-55.38. Based on the research results, it is recommended that the government and the management of Tanjung Buton Port pay attention to the management of pollutant sources around Tanjung Buton Port.

Abstract

The shrimp fishery in Kotabaru, South Kalimantan, is a small-scale fishery that supplies raw materials to PT. Sekar Laut, Tbk, a company specializing in shrimp cracker production for the global market. Despite its significance, limited research has been conducted on the sustainability of this fishery. This study aims to analyze the key characteristics of the shrimp fishery in Kotabaru waters. Data were collected from January to August 2024 in Kotabaru, South Kalimantan, and subjected to various analyses, including species composition, length-weight relationships for several shrimp species, and identification of shrimp fishing grounds. The results reveal that banana shrimp and yellow shrimp are the predominant species within the catch, both exhibiting negative allometric growth patterns. The fishery’s most productive fishing location is identified in Pantai Village, highlighting this area as a potential focus for sustainable management initiatives. These findings underscore the need for ongoing monitoring and targeted management practices to promote the long-term sustainability of the shrimp fishery in Kotabaru.

Abstract

Lift net is a fishing tool that belongs to the lifting net group. In terms of construction, there are two types of lift net, namely: stationary lift net and floating lift net. Stationary lift net are a type of static fishing gear. The advantage of this fishing gear is that it gives fishermen certainty about the fishing location. However, if fishermen are not wise in exploiting fish, the catch will decrease, the reason is that stationary lift net will rely heavily on the stock/abundance of local fish in these waters. This is different from floating lift net which are able to change positions. The method is to pull the lift net with the help of the boat. Usually fishermen will move the position of any lift net when the catch is low or the weather is bad. Thus, research was carried out regarding the effectiveness and efficiency of the operation of the lift net by conducting experimental fishing in Probolinggo waters. The results of the independent t test show a significance value of 0.152, which means there is no difference in catches between the stationary lift net and the floating lift net.

Abstract

Mangrove ecosystems are important for maintaining ecological balance in coastal areas. To monitor changes in mangrove area and density, remote sensing technology with Landsat 8 and NDVI Index was used. The research focuses on the North Coast of East Java, from 2019-2024, on the coast of Surabaya, Sidoarjo, Pasuruan, Probolinggo, and Situbondo. The purpose of this study is to analyze changes in mangrove area and density. The survey method was conducted with Landsat 8 images and in situ data in 2024. There are 5 observation station points with the determination of station points using purposive sampling technique. Accuracy test using RMSE. The area of mangroves on the coast of Surabaya, Sidoarjo and Pasuruan from 2019 to 2024 ranged from 1611.88 ha-2270.41 ha. The highest cover area was in 2024 and the lowest in 2019. Mangroves with sparse NDVI category ranged from 46640.61 ha-53284.95 ha. Moderate NDVI ranged from 4313.25 ha-6984.72 ha and dense NDVI ranged from 493.29 ha-4711.5 ha. The area of mangroves on the coast of Probolinggo and Situbondo increased from 2019-2024, which amounted to 1487.05 ha-1885.79 ha. Mangroves with sparse NDVI category have an area between 51367.12 ha-54852.64 ha. Moderate NDVI ranged from 5564.87 ha-54852.64 ha and high NDVI ranged from 668.18 ha-1585.52 ha. The results show that there are changes in the area and density of mangroves on the north coast of East Java every year. These changes need to be monitored annually to address the decline in mangrove area and density quickly and appropriately.

Abstract

Squid (Loligo spp.) belongs to the Cephalopoda group (squid, cuttlefish, octopus) and is one of the primary export commodities in the fisheries sector. National squid production increased by 5.5%, from 193,583.82 tons in 2020 to 204,156.28 tons in 2021. However, the potential sustainable catch in the Java Sea (WPPNRI 712, including the Madura Strait) has experienced an average annual decline of 1.9% from 2017 to 2022, dropping to 66,608 tons in 2022. This study aims to identify the species composition of squid, analyze length-weight relationships, and determine the mantle length at first gonad maturity (Lm). Data were obtained from fixed lift-net catches and analyzed in the Fisheries Exploitation Laboratory of Universitas Brawijaya. The results identified two main species: Photololigo duvaucelli (Indian squid) and Sepioteuthis lessoniana (bigfin reef squid). The composition of squid catches was 1.29% in purse seine operations and 2.91% in payang (seine net) operations. The length-weight relationship of both species exhibited a negative allometric growth pattern, where length growth outpaces weight gain. The sex ratio between males and females was balanced for both species. The mantle length at first gonad maturity (Lm) was greater than the mantle length at first capture (Lc), indicating that the catch was dominated by immature squid. These findings highlight the need for minimum catch size regulations to ensure the sustainability of squid resources in the Tuban waters.

Abstract

Two-wheeled motor vehicles are a major source of urban air pollution. This study investigates the emissions of carbon monoxide (CO) and hydrocarbons (HC) from motorcycles operating within the Environmental Engineering Department of Universitas Tadulako. Emission data were collected using direct measurements with an automotive emission analyzer across various motorcycles differing in age, fuel type, and engine condition. The findings reveal that, although the average emission levels generally meet the national standards (Ministerial Regulation No. 8/2023), motorcycles using lower-grade fuel (Pertalite) emit higher concentrations of CO and HC compared to those using higher-grade fuel (Pertamax). Furthermore, both CO and HC emissions increase with the age and mileage of the vehicle. The correlation analysis indicates that older vehicles and those with higher mileage tend to release more pollutants due to reduced engine efficiency. These results underscore the importance of regular vehicle maintenance, the use of higher-quality fuels, and awareness campaigns to reduce air pollution on campus. The study supports the development of environmentally friendly transportation policies within educational institutions. ASSESSMENT OF TWO-WHEELED VEHICLE EMISSIONS IN THE VICINITY OF THE ENVIRONMENTAL ENGINEERING DEPARTMENT, UNIVERSITAS TADULAKO, INDONESIA

Abstract

The Maloy Batuta Trans Kalimantan (MBTK) Special Economic Zone (SEZ) in East Kutai Regency has significant potential for developing industries based on natural resources, particularly in palm oil and minerals. This study aims to assess the potential of leading sectors and evaluate the effectiveness of the MBTK SEZ development policy using a policy analysis approach, Location Quotient (LQ), and Shift Share analysis. The findings indicate that both national and regional policies have supported the growth of local resource-based industries; however, their implementation has not been optimal due to low investment levels and inadequate infrastructure. This study recommends aligning cross-sector policies, accelerating the provision of essential infrastructure, and implementing industrial clustering strategies to enhance the competitiveness of the MBTK SEZ.

Abstract

Japan is an archipelagic country with numerous marine commodities of high economic value. One of the most popular marine products among the Japanese population is the Hotate scallop (Mizuhopecten yessoensis). Hotate scallops are a type of shellfish that thrive in low-temperature environments, with their natural habitat commonly found in the northern seas of Japan, particularly in Hokkaido. Suzuki Toshihiko Company, located in Toyoura, Hokkaido Prefecture, is one of the companies engaged in the Hotate scallop industry. This study was conducted to examine the Mimizuri cultivation technique used by Suzuki Toshihiko Company. The study are divided into 3 methods ; the first method include observation; the second active participation, and the third method interview to collect primary data, while secondary data were obtained from relevant literature. The Mimizuri technique is a method of cultivating Hotate scallops by attaching them to a rope and raising them in the open sea. This technique involves several stages, starting with seed collection, seed sorting, the mimizuri stage, and finally the large-scale harvesting stage

Abstract

Mangrove ecosystems are recognized as vital blue carbon reservoirs that contribute significantly to climate regulation through biomass-based carbon storage. This study assessed mangrove diversity, structure, biomass, and carbon stocks in two key locations: Banyuurip Mangrove Center (BMC) and Lewean Mangrove Park (LMP), located in the Ujungpangkah Estuary, Gresik. Data were collected from 15 rectangular plots (10 × 10 m) to determine species composition, tree density, Importance Value Index (IVI), above and belowground biomass, and estimated carbon stocks using standard allometric equations. A total of 12 mangrove species were identified, with Avicennia marina emerging as the dominant species in all growth stages across both sites. Tree density varied from 100 to 1,600 trees/ha, reflecting stages of regeneration rather than degradation. The highest IVI values were recorded for A. marina (196.3% in BMC; 146% in LMP). Total biomass and estimated carbon stock were higher in BMC (340.48 Mg/ha; 164.87 Mg C/ha) compared to LMP (125.67 Mg/ha; 56.20 Mg C/ha), primarily due to differences in species dominance and stand maturity. These results underline the ecological and climate mitigation significance of maintaining mangrove diversity and biomass. The study supports the integration of mangrove conservation into blue carbon strategies for sustainable coastal management, and recommends strengthening local restoration initiatives based on dominant species performance.
