Length Frequency and Sex Ratio of Bullet Tuna (Auxis rochei) Landed at Ternate Archipelago Fishing Port, Indonesia
This study aims to analyze the length distribution and sex ratio of bullet tuna (Auxis rochei) landed at Ternate Archipelago Fishing Port Ternate (PPN Ternate). Sampling was conducted in June and July 2024 with 100 fish per month. Observations included total length measurements and sex identification to determine size distribution patterns and sex composition. The results showed that male fish in June had the highest frequency at class interval of 190-201 mm, and in July it shifted to class interval 226-237 mm. Meanwhile, female fish in June were dominant in the class interval of 201-210 mm, and in July increased to the class interval of 231-230 mm. The sex ratio in June was 1:1.22 (male:female), while in July it was 1:0.82. The results of the chi-square test showed that the difference in sex ratio was not statistically significant (p > 0,05), so the population was considered to have a balanced sex composition. This finding is in line with several previous studies in the Indonesian region that showed variations in size structure and sex ratio of Auxis rochei influenced by seasonality, reproductive migration, and fishing activity. This study provides important basic information to support sustainable management of bullet tuna (Auxis rochei) resources in North Maluku waters.

Local Fishermen’s Preception of Measured Fishing in WPPNRI 714
The issue of equitable access for local fishermen to marine resources remains a critical concern in the implementation of Measured Fishing (PIT) policies in Indonesia. This study aims to analyze the perceptions of local fishermen regarding PIT, with a specific focus on their access rights in Fisheries Management Area (WPPNRI) 714. The research was conducted from September to November 2023 in several coastal areas in Ambon Island and Banda Neira, Central Maluku. The survey targeted local fishermen operating ring seine (jaring bobo) vessels larger than 5 GT in the villages of Latuhalat, Laha, Waai, and Hitu. Respondents were selected using purposive sampling, and data were analyzed descriptively. Results indicate that most vessel owners support PIT, perceiving its benefits in sustaining fish stocks, optimizing profits, improving data accuracy, and increasing non-tax state revenue. However, many fishermen disagree with the obligation to pay landing fees at designated ports, viewing it as an additional burden. The findings reveal that while the ecological and economic aspects of PIT are generally well-received, issues related to fairness, administrative obligations, and economic impact remain contentious. In conclusion, the successful implementation of PIT requires adaptive and inclusive policies that prioritize sustainability while ensuring the economic viability of local small-scale fishers. These insights are expected to support both regional and national policymakers in formulating fair and context-sensitive fisheries governance.

Analysis of the Effectiveness and Environmental Friendliness of Bottom Hand Line Fishing on the Datoe, Batavier, and Ender Coral Reefs in the Waters of Maas Island, Tual City, Maluku Province
This study aims to analyze the effectiveness and environmental friendliness of bottom hand lines used by fishers around the coral reefs of Datoe, Batavier, and Ender. Labetawi Village was selected as the research site because most of its fishers actively use this gear traditionally and apply selective fishing practices that have the potential to serve as a model for environmentally friendly fisheries in the Tual region. This study analyzes five key parameters: catch efficiency, bycatch-to-target ratio (B/T Ratio), Catch Per Unit Effort (CPUE), gear selectivity, and environmental friendliness. The results show high catch efficiency (76–77%), peaking in July–August at 77.34%, while bycatch remains low (22.66–24.13%). The B/T Ratio values are consistently low and stable, indicating good gear selectivity. The CPUE of target fish was consistently higher than that of non-target fish, although a declining trend was observed from April to September, likely due to fishing pressure and habitat degradation. Bottom hand lines also demonstrated high selectivity, with 79.23% of the catch consisting of target species. Based on nine ecological assessment criteria, a total environmental friendliness score of 33.6 categorizes this gear as environmentally friendly. Thus, bottom hand lines are considered effective and selective in catching target species with minimal ecological impact. Their use is strongly recommended as part of an ecosystem-based fisheries management strategy, with the fishing practices of Labetawi Village serving as an example of efficient, selective, and sustainable traditional fisheries.

The Feed Conversion Ratio and Feed Digestibility of Feed Substituted with Azolla microphylla Meal for Tilapia Fry
The high cost of commercial fish feed and the limited availability of highly nutritious, cost-effective, and environmentally friendly feed ingredients pose challenges in producing high-quality tilapia fingerlings (Oreochromis niloticus). The efficiency of nutrient absorption in fish digestion and growth performance is generally evaluated through the feed conversion ratio (FCR) and digestibility values. This study aimed to determine the effect of substituting commercial feed with fermented Azolla microphyll meal on the proximate composition and digestibility of tilapia fingerlings. The study was conducted from June to July 2024 at the Tanabangka Village Fish Hatchery Unit, Bajeng Barat District, Gowa Regency, and at the Brackishwater Preliminary Aquaculture Research Laboratory in Maros. The research employed a completely randomized design with four treatments and three replicates. The treatment groups were as follows: A) 100% commercial feed as control, B) 25% commercial feed and 75% Azolla meal, C) 50% commercial feed and 50% fermented Azolla microphyll meal, and D) 75% commercial feed and 25% fermented Azolla microphylla meal. The results showed that fermented Azolla microphyll meal can serve as a viable alternative to commercial feed. A feed composition of 50% commercial feed and 50% fermented Azolla microphylla meal yielded an FCR of 1.37±0.05. Meanwhile, combining 75% commercial feed with 25% fermented Azolla microphyll meal produced total and protein digestibility values of 84.51±0.78% and 92.47±0.59%, respectively. These findings suggest that integrating fermented Azolla microphylla into feed formulations can enhance nutrient utilization efficiency and reduce dependence on commercial feed in tilapia aquaculture.

Efforts to Prevent Risk Factors for Stunting in Toddlers Through Socialization of Fish-Based Food Processing in Bangko Village
Stunting is one of the global nutritional problems in children, where around 161 million toddlers in the world experience stunting. Education and family understanding of nutrition have an impact on stunting. West Halmahera Regency ranks first in the number of stunted toddlers compared to other districts/cities in North Maluku. The prevalence of children under five (toddlers) who have short and very short nutritional status in 2018 was 35.26%. When viewed from the consumption patterns of toddlers in Bangko Hamlet, they generally consume more than one type of carbohydrate, including rice, cassava, and sago. Most of them only consume vegetable side dishes such as tempeh and tofu 2-6 times per week. As for animal-based dishes, more than 90% of them consume these every day and at least once a day. The general objective of this PKM is to improve the knowledge and skills of mothers of toddlers in compiling menus and processing local fish-based food ingredients as an effort to prevent stunting in toddlers. The method used in this study was to socialize and demonstrate fish-based menus in an effort to reduce stunting rates as a form of prevention. The results of community service can be seen from the increase in community knowledge in three aspects: knowledge of efforts to prevent stunting (89.1%), knowledge of making banana fish porridge (73%), and knowledge of fish roulade with the addition of carrots (67.6%).

Characteristics of White Bread with Duckweed Flour (Lemna sp.) Subtitution as Functional Food
Processed food products like white bread are favored by various segments of Indonesian society. White bread is widely favored because of its delicious taste, affordable price, and convenience. However, the nutritional components of white bread products are generally dominated by carbohydrates with little protein and fiber. One way to enhance the nutritional components and create functional properties in white bread is by substituting wheat flour with duckweed flour. The potential of duckweed as a food ingredient is well-known due to its high protein and fiber content. Duckweed is also known to have the ability to act as a stabilizer, emulsifier, foaming agent, and thickener in added foods. This study aims to determine the optimal amount of duckweed flour substitution for the characteristics of white bread. The method used in this research is a Completely Randomized Design (CRD) consisting of 4 treatment levels (0%, 1%, 3%, and 5%) with 2 replications. This research has two main stages: the production of duckweed flour and the making of white bread. The testing parameters in this study include proximate analysis, crude fiber analysis, swelling power analysis, hardness analysis, slice appearance analysis, hedonic analysis, and Bayesian test. The substitution of 3% duckweed flour (F2) became the best treatment with proximate analysis showing moisture content of 3.47%, ash content of 4.67%, fat content of 2.61%, protein content of 14.09%, and carbohydrate content of 75.18%. Physical analysis showed a hardness of 1.905 N, a swelling power of 135.83%, and a good appearance of the slices.

Relationship Between the Role of Extension Workers and the Implementation of Farmer Group Functions
Farmer groups serve as a crucial medium for enhancing farmers’ skills, while agricultural extension officers play an important role in assisting and facilitating farmers to become more productive and competitive. This study aimed to (1) analyse the significant role of farmer groups in supporting horticultural farmers in Limumir village, (2) examine the role of agricultural extension officers in horticultural farmer groups, and (3) analyse the correlation between the role of agricultural extension officers and the function of farmer groups. This study employed both quantitative and qualitative approaches. Research population consisted of 68 members of horticultural farmer groups in Limumir village, from three farmer groups: Maju Bersama, Suka Maju, and Fajar Tani. Data were collected through observations, interviews, questionnaires. The data were then analysed using Spearman's Rank Correlation test to examine the correlation between the role of agricultural extension officers and the function of farmer groups. The results revealed that the role of agricultural extension officers as facilitators and assistants to farmers had a significant impact on the efficiency of farmer groups in learning as collaboration aspects. Farmer groups with intensive supervision from agricultural extension officers showed increased technology adoption, better access to the market, and higher productivity. However, the role of agricultural extension officers in marketing was low, so a number of farmers still face challenges in accessing broader markets.

Coral Reef Ecosystem Sensitivity Study to Waste Pollution
The coral reef ecosystem on Karimunjawa Island has an important ecosystem service value for the socio-economic life of the community. The many tourism activities result in pollution in the waters that can disrupt and even damage the balance of the coral reef ecosystem. This study was conducted to determine the extent of the impact of pollution caused and to develop an appropriate coastal pollution management strategy in overcoming pollution problems due to waste disposal activities. The method used in the study is the exploratory descriptive method. The exploratory descriptive method is a research method that is observational of an object in its natural environment, without any treatment of the object being studied. Data collection was carried out at 4 research locations, namely Tanjung Gelam, Karimunjawa, Batulawang and Sntok. The study can be analyzed using the CPCE (Coral Point Count with Excel) method. This method is used to determine the condition of coral reefs at a location. The highest value was obtained at the Sintok location while the lowest condition was on Karimunjawa Island. The average percentage summarizes live corals included in the moderate to very good category ranging from 23.89% - 77.67%. The results of the analysis show that in the horizontal cross-section the condition of the coral reef is better compared to the vertical condition. The weight of waste in the coastal area is highest in the Karimunjawa area and the least is in the Sintok Island area.

Composition, Distribution, and Diversity of Gastropod Species in The Estuarine Waters of Kaiyasa and Oba Village, Tidore Islands City, North Maluku
Estuaries are one of the habitats for gastropods that have not been widely explored in North Maluku. This study aims at assessing the ecological conditions of gastropods in the estuarine waters including their composition, distribution, density, and species diversity. The study was conducted in August 2024 in the estuarine waters of Kaiyasa Village (Station 1) and Oba Village (Station 2). Data collection was carried out using the Quadratic Linear Transect Method. The results of this study found six species of gastropods with the highest composition found at Station 1 as 6 species, namely Faunus ater, Telescopium telescopium, Terebralia palustris, Cerithium coralium, Nassarius olivaceus, and Chicoreus capucinus compared to Station 2 as two species namely F. ater and T. palustris. F. ater which dominated both research stations since they were found in large numbers, namely 342 individuals (93%) at Station 1 and 299 individuals (98%) at Station 2. F. ater also had the highest density values of all species of gastropods found, namely 19.00 ind/m2 (Station 1) and 16.61 ind/m2 (Station 2), while C. coralium and C. capucinus have the lowest density values of 0.11 ind/m2. In general, the ecological conditions of gastropods at both research stations indicate a relatively low level of species diversity (H’ = 0.1 – 0.34), with low species evenness (E = 0.14 – 0.19), and indicated the dominance of certain species (C = 0.87 – 0.96), namely F. ater. The quality of the estuary water environment at both stations was still suitable for supporting gastropod life.
