Abstract

Flying fish of the Exocoetidae family are abundant in the east monsoon. This fish has important economic value because it is consumed by the public and its eggs are an export commodity. The problem encountered, Ambon Island fishermen only use the fish, the eggs do not. This is due to the unfavorable east monsoon and limited fishing vessels and skills, even though the utilization area is very close to settlements. Therefore socialization of fishing techniques is deemed necessary to improve people's welfare. The socialization was carried out in the Hukurila State PKK Room, Ambon City, Saturday, June 3, 2023, with 29 fishermen. Submission of material in the form of presentations, questions and answers, and discussions. The results of this activity are introducing fishing techniques and utilizing flying fish eggs as an alternative to fishing in the east monsoon. This socialization was welcomed by the fishermen and the government of the country, who agreed to realize this program the following year supported by village funds and youth.

Abstract

The Tanimbar Islands are an area of high tectonic activity and are part of the outer arc island chain formed by subduction in the Banda zone. The presence of the Sorong Fault and Tanimbar Fault around the Tanimbar Islands also affects the level of vulnerability to earthquakes and tsunami hazards. The purpose of this study was to predict the tsunami potential and affected area of the Tanimbar Islands. The method of analyzing the height data and predicting the affected area used COMCOT v1.7 software. Model simulations were performed on the domain layer by using linear equations. Earthquake and fault parameter data were obtained from the USGS website using historical earthquakes dated January 10, 2023. Bathymetry data were obtained from the GEBO website at a resolution of 15-arcsecond (464 m). The model simulation results show that the initial wave height value marked by the red contour is 0.22 m and the lowest low tide value marked by the blue contour is -0.4 m. Based on these results, the tsunami potential in the Tanimbar Islands is not dangerous, as the potentially affected areas in the study area are Selu Island, Woluaru Island, Wotap Island, and Molu Island, as well as the small islands in the western part. The simulation results demonstrate the importance of research related to tsunami hazards that may occur in the future so that appropriate mitigation can be planned for the existence of small islands around the Tanimbar Islands.

Abstract

The effect of additive corn cob ash (CA) on Portland Composite Cement (PCC) on the compressive strength of the mortar is influenced by pozzolan. The material that makes up pozzolan is silica. Corn cobs are agricultural waste that contains silica and every year continue to increase, so corn cob waste is as an additional material to Portland Composite Cement (PCC). This study was conducted to determine the compressive strength value of mortar using additive corn cob ash (CA) and corn cob ash that has been washed with HCl 2N (CA*) and the feasibility of these additives as a PCC-type cement mixture. The weight percentages of additives used were 5%, 10%, and 15%, and the duration of the mortar compressive strength test was 3, 7, and 28 days. The experimental results showed that the compressive strength (σm) was highest at the addition of 5% additives, the effect of additives on compressive strength resulted in σm research > standard σm (SNI). The results of the activation index analysis obtained additive corn cob ash of 76% and corn cob ash+HCl 2N of 76.71%, the value is above the minimum limit according to ASTM C.618-99 which is 75%.

Abstract

Kalanchoe pinnata leaves are rich in bioactive compounds, including flavonoids and phenolic constituents, which exhibit notable antioxidant properties. However, the efficiency of extraction processes is highly influenced by operational variables such as the type of physical pre-treatment and maceration duration. This study aims to evaluate the effect of three physical pre-treatment methods (manual grinding, chopping, and blending) and maceration periods ranging from 3 to 5 days on the antioxidant activity of K. pinnata leaf extracts using the DPPH radical scavenging assay. Results indicate that the grinding method combined with five days of maceration yields the highest antioxidant activity (95.04%), while blending leads to the lowest activity (81.78%), presumably due to heat-induced degradation of active compounds. Kinetic observations show that antioxidant activity tends to plateau on day five, particularly in ground samples. These findings highlight the critical influence of particle size reduction and solvent–solid contact time on mass transfer efficiency during extraction. This preliminary investigation provides a scientific basis for further research on the optimization of natural antioxidant extraction processes and the development of functional herbal formulations derived from K. pinnata leaves.

Abstract

The eastern Seram waters are influenced by both the Seram Sea and the Banda Sea. This study aimed to examine variations in wind, surface currents, and sea surface temperature (SST) during 2015, coinciding with the super El Niño event. Data were obtained from the Group for High Resolution Sea Surface Temperature (GHRSST) and the Copernicus Marine Environment Monitoring Service (CMEMS). The results indicated that the monthly average wind speed in this area ranged from 0.01 to 8.98 m/s, with the lowest speed in November and the highest from January and June to September. Surface currents also exhibited seasonal variability, flowing from the Seram Sea to the Banda Sea during the west season (December–January) and reversing eastward in February. During the east season, Banda Sea water masses were supplied by Seram Sea water. Sea surface temperature decreased notably from June to August, with the lowest temperature recorded in August due to upwelling in the Banda and Arafura Seas. Surface currents formed eddies with warm water centers in the northern part of eastern Seram waters, and cold water centers (25,4 °C) were also observed. The convergence of these two water masses with distinct characteristics generated thermal fronts with temperature differences, resulting in strong temperature gradients from August to October as a consequence of upwelling and cooling induced by the intense El Niño at the end of 2015.
