The objective of this study was to optimize the productivity of nutmeg (Myristica fragrans Houtt) through the application of concentration levels and frequency of liquid organic-inorganic mixed plant nutrition was carried out in the Nutmeg Garden of Hative Besar Village, Ambon Island, using a factorial complete randomized block design 3 x 2 + 1 (control, without treatment). The first factor consisted of three concentration levels, namely 1500 ppm, 3000 ppm, and 4500 ppm. The second factor consisted of two application frequencies: every two weeks and every four weeks. The sample employed in this study had an average age of 25 years. Each treatment combination was repeated three times with the total sampled 21 trees. The following yield parameter components were observed in this study: number of harvested fruits, fresh fruit weight, wet seed weight, dry seed weight, and dry mace weight. The results showed an interaction between the combination treatment of liquid organic-inorganic mixed plant nutrient concentrations and the frequency of application to the variables of fresh fruit weight, wet seed weight, dry seed weight, and dry mace weight. The variable number of fruits harvested per plant did not show an interaction effect between the concentration level and the frequency of giving liquid organic-inorganic mixed plant nutrition. Still, the best average number of fruits harvested per plant was found in the combination treatment between a concentration of 3000 ppm and a frequency of application every two weeks. The application of liquid organic-inorganic mixed plant nutrition with a concentration of 3000 ppm with a frequency of application every two weeks showed a positive response to increasing plant productivity when compared to other treatments or without the application of plant nutrients.

This bibliometric study examines how the field of sustainable crop management research is developing through an analysis of publications and their citations. We use VOSviewer software and sophisticated bibliometric approaches to find emergent research subjects, co-authorship networks, trends, and influential publications. Our data shows a significant increase in research publications over the course of four decades, which is indicative of the growing understanding of the significance of sustainable agriculture. Key publications by well-known writers offer fundamental information, and co-authorship networks emphasize cooperative research initiatives. Agroecology and climate-resilient agriculture are two emerging study subjects that provide insights into the field's future orientations. Through an awareness of these trends and key publications, this research helps to support well-informed decisions about food security and sustainable agriculture.

This research aimed to obtain land characters and qualities data and to determine land suitability for clove and nutmeg and their spatial distribution in Nusalaut Island, Central Maluku Regency. The results showed that the land suitability for clove are marginally suitable class (S3) with the coverage area is 1452.38 ha or 66.51%, and the limiting factors are water availability and nutrient retention (wa, nr) limiting factors and unsuitable class (N) of 731.52 ha or 33.50 %. While the land suitability for nutmeg are moderate suitable (S2) with root media and nutrient retention (rc, nr) limiting factors and the coverage area is 123.75 ha or 5.66%, S2nr of 409.93 ha or 18.77%, slope (S2eh) limiting factor with the coverage area is 918.7 ha or 42.1% and the unsuitable class (N) with the area of 731.52 ha or 33.50 %. The land suitability of the clove and nutmeg is located in the Other Used-Areas (APL) with the area of 2183.63 ha, while total land units in the study area is 2697 ha.

This study aims to identify sources of pollution and determine the magnitude of the potential pollution load from pollutant sources in the Wai Batu Merah watershed, Sirimau District, Ambon City. The method for identifying sources of pollution is carried out by using saturated or census sampling methods, calculating pollutant loads using direct methods for point source pollutant sources and indirect methods for non-point sources . The direct calculation method uses wastewater discharge data and the results of wastewater quality analysis results from measurements directly at the point source pollutant wastewater treatment plant (WWTP). The wastewater sampling technique uses the grab sampling method. While the indirect method uses effluent factors and supporting data from non-point source pollution sources that have been identified in the Wai Batu Merah watershed. The results showed that the pollutant sources found in the Wai Batu Merah watershed were point sources originating from hotel and health facility activities and non-point sources originating from domestic activities from residential areas, agricultural and livestock businesses, non-point source land (forest and open land), micro, small and medium enterprises (MSMEs), small scale industries and waste. The dominant pollutant source in the Wai Batu Merah watershed comes from domestic non-point sources. The highest point source pollution loads for BOD, COD and TSS parameters in the Wai Batu Merah watershed came from hotel activities in segment 6 with the contribution of each parameter of 17.82 kg/day, 23.82 kg/day and 0.029 kg/day. Meanwhile, the highest non-point source pollution load for BOD, COD and TSS parameters came from non-point source waste in segment 6 with the contribution of each parameter of 2825.3 kg/day, 3884.8 kg/day and 2684.03 kg/day.

This study investigates the meteorological factors contributing to extreme rainfall events and their relationship with flood occurrences in Ambon City. Based on a comprehensive global analysis of several atmospheric parameters, the results reveal: (1) a closed circulation pattern (streamline) over the Karimata Strait and Cenderawasih Bay, leading to the convergence and deceleration of easterly winds; (2) high atmospheric humidity ranging from 80% to 100%, coupled with warm sea surface temperatures (26–30°C), which significantly increase water vapor availability for cloud formation and development; and (3) a Southern Oscillation Index (SOI) of +10.39 and a Niño Index of -0.8, indicating the presence of a weak La Niña phenomenon that contributes to increased rainfall across Ambon City and the Maluku region. These atmospheric conditions collectively elevate the potential for hydrometeorological disasters, including severe flooding (BMKG, 2024). Ambon City, located within the Maluku Islands, exhibits a distinct local rainfall pattern that contrasts with Indonesia’s monsoonal climate, with its peak rainy season occurring from June to August, coinciding with the national dry season. This study aims to analyze the physical atmospheric conditions during extreme rainfall events and their influence on flood occurrences in Ambon City. Utilizing a descriptive-analytic approach, the research focuses on real field events to explore the underlying mechanisms driving these phenomena. The findings demonstrate a significant correlation between extreme rainfall and flood events, with atmospheric indices confirming conditions that favor intense convective activity, prolonged heavy rainfall, and subsequent flooding.

El Nino is one of the global phenomena that has affected the climate system of Indonesia. One of the direct impacts of the El Nino phenomenon is the decrease of water availability on agricultural land. This study aimed to analyze the period of El-Nino extreme rainfall events and to analyze the impact of El Nino extreme rainfall events on the availability of ground water for plant growth and determining planting times in areas with local rainfall patterns and equatorial rainfall patterns. This study uses several elements of Meteorological weather parameters, namely, temperature, wind speed, air humidity, sunlight and rainfall over a period of 30 years (1994-2023). The approach used is descriptive-analytical, emphasizing the analysis of average rainfall data, analysis of extreme El Nino rainfall, analysis of land water balance and analysis of planting seasons. Based on the results of the analysis and discussion, it was found that El Nino extreme rainfall has a significant influence on areas with local rainfall patterns and equatorial rainfall patterns. The role of the government is needed by providing counseling and socialization to prepare farmers to adapt to climate change.Further research is needed to examine the planting season adaptation strategy based on the type of plant that is appropriate to the extreme water deficit conditions due to El-Nino
