Abstract

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.

Abstract

ABSTRAK Daya simpan panas (DSP) gerabah vorno merupakan suatu kebutuhan untuk meningkatkan produksi sagu lempeng. Metode eksprimen penambahan aluvial pada pembuatan gerabah dengan komposisi tanah liat 40 %, aluvial 25% dan pasir pantai 35%  sebagai gerabah pengembangan diharapkan dapat meningkatkan DSP gerabah. Keterbatasan instrumen pengujian DSP secara teknik, membutuhkan solusi secara statistik dalam mendeterminasi DSP. Perbandingan hasil analisis dari pendekatan metode linear dan non linear pada data perubahan suhu lempengan membentuk karakteristik tertentu, olehnya itu dibutuhkan identifikasi analisis statistik yang tepat dalam mendeterminasi DSP dengan akurasi tinggi. Hasil penelitian menunjukkan bahwa penggunaan material aluvial pada pembuatan gerabah meningkatkan berat jenis lempengan gerabah. Koefisien determinasi (R2) dari keseluruhan persamaan metode linear dan non linear memberikan linearity yang tinggi (R2 > 75%), akurasi tertinggi dengan nilai mean absolute percent error (MAPE) < 10% dijumpai pada tren persamaan kubik dan logaritmik. Pendekatan tren kubik menunjukkan DSP gerabah pengembangan lebih lambat 7% dibandingkan dengan gerabah rujukan, sedangkan penggunaan tren logaritik lebih lambat 33%. Perlu dilakukan analisis data dengan perhitungan transfer panas untuk membuktikan DSP dengan pendekatan statistik. ABSTRACT The heat storage capacity (HSC) of vorno pottery is a necessity to increase the production of sago plates. The experimental method of adding alluvial to pottery making with a composition of 40% clay, 25% alluvial and 35% beach sand as development pottery is expected to increase the DSP of pottery. The limitations of technical DSP testing instruments require a statistical solution in determining DSP. Comparison of analysis results from linear and non-linear method approaches on slab temperature change data forms a specific characteristic, therefore it is necessary to identify the right statistical analysis in determining DSP with high accuracy. . The results show that the use of alluvial materials in pottery making increases the specific gravity of pottery slabs. The coefficient of determination (R2) of all equations of linear and non-linear methods gave high linearity (R2 > 75%), the highest accuracy with mean absolute percent error (MAPE) value < 10% was found in the cubic and logarithmic trend equations. The cubic trend approach showed that the heat retention of the development pottery was 7% slower than the reference pottery, while the use of the logarithmic trend was 33% slower. It is necessary to analyse the data with heat transfer calculations to prove the HSC with a statistical approach.

Abstract

The pedada fruit (Sonneratia alba), locally known as posi-posi, has potential as a raw material for herbal tea with various health benefits, such as lowering cholesterol, relieving gout, providing antioxidant effects, reducing gastric acidity, and supporting organ health. However, mangrove tea has not yet been widely marketed in North Maluku, and it is not available as a local tourism souvenir. This Community Service Program (PKM) aimed to: (i) increase partners’ knowledge of mangrove fruit as a business opportunity, (ii) apply appropriate technology in tea processing, and (iii) produce high-quality mangrove tea variants with market value. The implementation stages included: (1) knowledge delivery through presentations and discussions, (2) mangrove exploration along the Guraping tourism tracking route, and (3) demonstration of mangrove tea processing. The product was developed into five variants: TeOry, Tebal, TeGo, TTM, and PosiNaga. Each variant was packaged in tea bags and boxes, then evaluated using hedonic organoleptic testing based on color, aroma, taste, and texture. The results indicated that mangrove tea has promising potential as a distinctive tourism souvenir and as a new business opportunity for local communities.

Abstract

Graphical Abstract   Highlight Research DSAS based on geographic information systems has the ability to extract important information on the dynamics of shoreline changes, both accretion and abrasion. The dynamics of shoreline change in the short period of time 2018-2023 in the IWIP industrial area shows a very dynamic change process dominated by accretion. The conversion of beach into land was more prevalent than the process of shoreline retreat in the study area. The abrasion rate in this study area was categorized as moderate, while the accretion rate was categorized as very high due to construction activities.     Abstract The development of industrial estate infrastructure in coastal areas causes significant changes in coastal morphology. Despite extensive infrastructure development in coastal zones, limited empirical data exists on the shoreline dynamics of newly established industrial estates, particularly in Eastern Indonesia, thus highlighting the urgency of this study. This study investigates coastal morphology changes in the PT Indonesia Weda Bay Industrial Park (IWIP) industrial area over five years using Landsat 8 OLI level 2A satellite imagery and geospatial analysis. Shoreline extraction was performed using the Normalized Difference Water Index (NDWI) algorithm and analyzed with the Digital Shoreline Analysis System (DSAS) applying the Net Shoreline Movement (NSM), End Point Rate (EPR), and Linear Regression Rate (LRR) methods. The findings show that from 2018 to 2023, the shoreline in the PT IWIP area predominantly experienced accretion. The highest rate of shoreline accretion occurred in industrial zone, with a maximum of 147.58 m/year and an average of 36.56 m/year, while residential zones in the eastern and western regions experienced moderate abrasion, with a maximum of 12.32 m/year and an average of 4.11 m/year. Categorization followed standard DSAS criteria, where shoreline changes between 10–30 m/year were considered moderate, and changes above 30 m/year were classified as very high. Measurement accuracy was validated using high-resolution Google Earth imagery and Landsat metadata, ensuring positional accuracy within ±30 meters. These results highlight the rapid and spatially varied shoreline changes driven by industrial activities, emphasizing the importance of remote sensing in monitoring and managing coastal development impacts
