In 1623, Dutch authorities executed twenty-one alleged conspirators over a plot to seize a castle on a remote set of islands in what is now eastern Indonesia. In this landmark study, Adam Clulow ...presents a new perspective on the Amboina case that aims to move beyond the debate over guilt or innocence.
This study aims to evaluate landslide causative factors in landslide susceptibility assessments and to compare landslide susceptibility models based on the bivariate frequency ratio (FR), ...multivariate logistic regression (LR), and artificial neural network (ANN). The majority of landslide occurrences in Ambon, Indonesia is induced by heavy rainfall events where slope failures occur mostly on steep slopes thereby endangering municipality areas at the base of the hills. Eight landslide causative factors were considered in the landslide susceptibility assessments. The causative factors were elevation, slope angle, slope aspect, proximity to stream network, lithology, density of geological boundaries, proximity to faults, and proximity to the road network. The output susceptibility maps were reclassified into five classes ranging from very low to very high susceptibility using Jenks natural breaks method. Twenty percent of all mapped landslides were used as the validation of the susceptibility models. The validity and the accuracy of each model were tested by calculating areas under receiver operating characteristic curves (ROCs), and the areas under the curve (AUC) for the success rate curves of FR, LR, and ANN were 0.688, 0.687, and 0.734, respectively. The AUC for the prediction rate curve of FR, LR, and ANN were 0.668, 0.667, and 0.717, respectively. All findings of the models show good results with the accuracy of all models being higher than 66%. The ANN method proved to be superior in explaining the relationship of landslide with each factor studied.

On September 26, 2019, a significant, Mw 6.5, earthquake shook Ambon region, Indonesia, causing severe damage on the Island(s) of Ambon. Due to the complexity of the fault network and in-situ stress ...field it was, up to now, not possible to define the fault plane using data from the BMKG regional seismic network. In this study, we analyze the fault plane of the 2019 Ambon earthquake and the reactivation potential of the surrounding faults using local networks. Eleven stations were deployed to monitor the aftershocks from October 18th to December 15th, 2019 augmented with data of four regional stations. During the monitoring period, 1,778 events were identified comprised of 10,938 P- and 10,315 and S- wave arrival times. The locations of aftershock were determined in a stepwise approach, i.e. (i) initial location determination using a non-linear approach, (ii) updating the velocity model, and (iii) relative double-difference relocation. Slip inversion using teleseismic data was performed to infer of high strain relief of the mainshock and to compute its associated static stress transfer (ΔCFF). Based on aftershock distribution and finite fault modeling, we conclude that the Mw 6.5 Ambon earthquake occurred on a N-S oriented fault plane. Two clusters consisting of ~60% of total events are located at both tips of the plane. Another cluster ~30% was sharply aligned in a NE-SW trend, 10 km westward, starting by an Mw 5.2 event on November 2nd, 2019. The b-value of the NE-SW events is ~0.25 lower than the other clusters with a b-value of 0.85±0.14. ΔCFF imparted by the mainshock caused ~0.5 Bar stress increase on the NE-SW fault. We concluded that the NE-SW trend was the reactivation of a preexisting fault crossing Ambon Island. The triggered large aftershock caused further significant damages to already weakened infrastructure and, thus, had the largest mapped damage area.
•Dense local network for assessing source mechanism and triggered large aftershocks.•1,778 aftershocks with 10,938 P- and 10,315 and S- wave arrival times were identified.•Fault plane was identified using seismic cluster, slip inversion and stress transfer.•Reactivation of the vicinity fault network (Mw 5.2) due to an Mw 6.5 strike slip event.•Existing NE-SW fault in the Ambon and Seram Island might be critically stress.

Sampah laut terdiri dari bahan organik padat dan anorganik yang tidak mudah terurai, menumpuk, serta tersebar di laut dan pantai. Masalah sampah merupakan permasalahan mendasar yang hingga saat ini ...belum terselesaikan di berbagai belahan dunia, termasuk di Kota Ambon. Teknik pengumpulan data yang digunakan adalah observasi langsung dan pengambilan sampel sampah. Penentuan lokasi penelitian disesuaikan dengan jadwal pasang surut perairan pada bulan Agustus 2023 di Pantai Pintu Kota dan Pantai Airlouw, Kota Ambon. Hasil penelitian menunjukkan jenis sampah yang diperoleh adalah botol plastik, gelas plastik, potongan plastik, kemasan plastik, sabut kelapa, daun kering, batang kayu, kaleng besi, potongan besi, sandal, pampers, kain, styrofoam, spons, kertas, dan lain-lain. Hasil pengukuran sampah di Pantai Pintu Kota dan Pantai Airlouw masuk dalam kategori mega-debris (>1 m) dan makro-debris (>2,5 cm - <1 m), namun yang terbanyak pada kategori makro-debris (>2,5 cm - <1 m), yaitu 2 cm – 1,74 m. Berat sampah dengan rata-rata hasil yang tinggi yaitu di Pantai Pintu Kota sebesar 121 g pada saat air pasang dan 100 g pada saat air surut, sedangkan rata-rata berat sampah di Pantai Airlouw tergolong rendah sebesar 58 g pada saat air pasang dan 61 g pada saat air surut. Sampah plastik maupun sampah non-plastik lebih banyak ditemukan pada saat air pasang, hal ini dimungkinkan karena pada musim timur di Kota Ambon curah hujan cukup tinggi sehingga arus dan gelombang dapat membawa sampah hingga ke pesisir pantai.

Salafi community in Ambon have developed since the arrival of Laskar Jihad during the 1999 Ambon Conflict. Social dan religious competition has divided them, which is not only triggered by their ...interpretation of Islam but also by their efforts to gain religious influence and socio-religious dominance within the Islamic society. The research method used in this research is qualitative phenomenology. The research results found that for the Salafis, love for their homeland was proven during the COVID-19 pandemic; Salafi groups in Ambon also implement all policies issued by the Indonesian government without exception. Religious moderation is a fair and balanced attitude that does not exaggerate or belittle religion. Another characteristic of the moderation attitude shown is constantly repairing and avoiding damage. Salafi community in Ambon continue try to protect their faith, soul, reason, honor, lineage, and property. They respect fellow religious people, regardless their religious background and beliefs.
The coastal waters of Ambon Island have quite diverse ecosystems that allow for the presence of various organisms, one of which is gastropods. This study aims to analyze the correlation of some water ...parameters and Pb in sediment to the diversity of gastropods. The research method was carried out by observing the density, water quality parameters, and Pb metal in sediments. Water parameters were measured in situ and analyzed in the laboratory. The distribution of gastropods was analyzed through Principal Component Analysis (PCA). At the same time, the correlation analysis was carried out using the Pearson correlation approach using SPSS v.16. The results showed that the types of gastropods with the highest density in the waters of Ambon Island were Terebralia sulcata, Hebra corticata, and Nerita patula. While the species with the lowest density value were Nassarius olivaceus, Polinices didyma, Lunella cinerea, Conus eburneus, Cypraea isabella, Vexillum plicarium, and Columbella scripta. The Shannon-Wienner Diversity Index ranges from 1.253–2.622, and the diversity index ranges from 0.083-0.207. It was included in the low category caused by the disturbance of water pollution and Pb metal in sediments. Meanwhile, the dominance index ranged from 0.098 to 0.511 indicating species dominance at several observation stations. The waters' physical-chemical parameters strongly correlating with gastropod diversity are DO and Pb, with respective correlation values of r = 0.656 and r = -0.785.
Mahulette AS, Alfian A, Suyadi, Supriyanto, Situmorang J, Matatula AJ, Kilkoda AK, Nendissa JI, Wattimena AY. 2022. Type and morphological character of local clove (Syzygium aromaticum) from Maluku, ...Indonesia. Biodiversitas 23: 1301-1309. Maluku Islands are known as the origin for the distribution of cloves (Syzygium aromaticum L.) in the world, where the diversity of clove germplasm is high. So far, information on the diversity of local clove morphology in Maluku is still very limited. The study was aimed to characterize the morphological diversity of local clove accessions in Maluku. The study was conducted in three distribution areas in Maluku, namely Ambon Island, Seram Island, and Haruku Island. Characterization was carried out on 130 local clove accessions of Maluku based on 32 morphological characters. The exploration identified nine types of cloves, namely Tuni, Forest Clove, Raja, Boiselang, Zanzibar, Bogor, Jinten, Tae, Damar, and three variants of Forest Clove, two variants of Raja, and two variants Zanzibar. Forest cloves, Raja, Boiselang Jinten, Tae, Damar are classified as wild-type cloves, while Tuni, Zanzibar and Bogor cloves are classified as cultivated cloves. The Hierarchical Cluster Analysis (HCA) obtained 2 large groups of local cloves with 57% agro-morphological differences. The first group is Forest Clove and Boiselang, while the second group is other local clove accessions (Tuni, Jinten, Red Zanzibar, White Zanzibar, Bogor, Damar, Tae, and Raja). The Principle Component Analysis (PCA) shows a total diversity of 66.7% with 4 characters based on grouping. These cloves are also categorized into wild type, cultivated, aromatic, and non-aromatic types.
Liline S, Rumahlatu D, Zubaidah S, Salmanu S, Sangur K. 2024. Influence of physicochemical environmental factors on morphometric characteristics of macroalgae from Ambon Island, Indonesia. ...Biodiversitas 25: 1436-1453. Macroalgae are an essential part of the marine biodiversity of Ambon Island, requiring thorough investigation for conservation and cultivation purposes. Therefore, this study aimed to identify macroalgae and analyze the relationship of environmental physicochemical factors to morphometric characteristics of macroalgae from the coastal waters of Ambon Island, Maluku Province, between June and July 2023. Sampling was performed at four locations, i.e., Hutumuri, Alang, Aer Low, and Suli Villages, followed by laboratory morphometric identification and measurements. The results showed significant variations in the physicochemical environmental factors of the four locations, featuring temperatures ranging from 25.00-30.05°C, pH of 7.00-8.34, salinity of 31.00-32.00, and dissolved oxygen (DO) of 6.00-15.27. Furthermore, the substrate in each location differed, presenting sequentially as sandy coral, coral, sandy coral, and mud sand. 11, 10, 6, and 25 species were found in Hutumuri, Alang, Aer Low, and Suli, respectively. Each species, with distinct morphological characteristics and morphometric sizes, was distributed across the Chlorophyta, Ochrophyta, and Rhodofhyta classes. These observations provided crucial insights into the intricate relationship between environmental factors and morphometric characteristics, including full length, thallus width, and length, as well as holdfast length and width of both same-species and different macroalgae populations in Ambon Island.
Konflik di Maluku tahun 1999 meninggalkan bekas luka yang bertahan hingga 20 tahun. Fenomena ini tercermin dalam narasi masyarakat pascakonflik secara langsung yang terdapat dalam perbincangan ...masyarakat sehari-hari. Selama 20 tahun bertahan di Ambon sebagai pengungsi, masyarakat Kayeli mengalami berbagai macam pengalaman (baik pengalaman kekerasan maupun damai). Perjuangan yang dihadapi pengungsi Kayeli menggambarkan kerusakan yang terjadi akibat konflik berkaitan dengan pola-pola relasi komunal sekian tahun setelah perang selesai. Kondisi ini sayangnya tidak cukup mendapat perhatian dalam kajian tentang masyarakat pascakonfik. Tulisan ini bertujuan untuk mendeskripsikan perjuangan komunitas pengungsi sebagai kelompok masyarakat rentan yang hidup dengan narasi kekerasan pascakonflik di Ambon. Tulisan ini didasarkan pada data dari hasil wawancara mendalam terhadap delapan informan pengungsi Kayeli pada tahun 2023. Hasil penelitian menunjukkan bahwa pengalaman konflik yang digambarkan dalam kelompok ini menggambarkan diskriminasi dan perjuangan dalam hubungan komunal di daerah baru tempat mereka dimukimkan kembali dari desa-desa mereka yang dilanda perang. Tulisan ini menguraikan tanggapan para pengungsi terhadap narasi konflik berdasarkan keyakinan Kristen yang mereka anut. Berbagai tanggapan tersebut merupakan cara komunitas pengungsi terus menjalani kehidupannya dengan mengatasi narasi-narasi diskriminatif di komunitas baru mereka.
Essentially violent crime can occur wherever, anytime, and can be done by anyone without any distinction sex. That is guilty can male or female. The reality that occurs suggests that female also ...often perpetrated a violent crimes. Such as happened in the city of Ambon, which according to the data from Polresta P.Ambon and P. P lease, suggests that from 2017 until 2019, there are 14 ( fourteen ) violence made by women on jurisdiction. That has been a problem in writing this is what has been factor-factor cause violence carried out by women in the city ambon. Factors influencing the so that a woman committed violence in the city of Ambon is the family, the motivation, / sexual disorder of sexual perversion, and the role of the victim
