Abstract

Microalgae are photosynthetic microorganisms that are widely distributed in waters. They have the potential as an alternative source of pigments, lipids, proteins, and carbohydrates. In this study, identification and isolation of single-cell microalgae from Ambon Bay were carried out by serial dilution method and inoculation of the culture by appearance/spread on the surface of the solidified agar medium. The results showed that the waters of Ambon Bay have physical parameters such as temperature, pH, salinity, and TDS, which are still within the threshold specified in the seawater quality standard for biota. The water conditions at the 10 sampling locations had different salinity, pH, temperature, and TDS. This condition affects the distribution of microalgae in the waters in Ambon Bay. The image from light microscopy shows that there are 27 species of microalgae scattered in the waters of Ambon Bay, which belong to the classes Chlorophyceae, Flagilariophyceae, Bacillariophyceae (diatoms), Coscinodiscophyceae, and Dinophyceae. Microalgae isolation obtained five species (single-cell) including four species from the class Bacillariophyta (Navicula sp, Nitzschia sp, Cyclotella sp) and one species from the class Chlorophyta (Chlorella sp).

Abstract

This research was conducted from January to March 2021 in the seagrass ecosystem of Amahai village, Maluku Tengah Regency. This study aims to analyze the structure of seagrass communities, identify utilization forms of the seagrass ecosystem, and formulate management directives in Amahai waters. Environmental parameter measurements included temperature, salinity, pH, current speed, and substrate conditions. Data collected to analyze the forms of ecosystem use were carried out in observation and interviews. Management directives were devised descriptively based on the results. The study shows that six types of seagrass are found, namely Enhalus acoroides, Halophila ovalis, Thalassia hemprichii, Cymodocea rotundata, Halodule pinifolia, and Syringodium isoetifolium. The highest value of species density, frequency, and proportion of closure is represented by Thalassia hemprichii which are 64.22 stands/m2, 0.74, and 17.77%, respectively; while the lowest value for species density and frequency is Syringodium isoetifolium that totals 11.69 stands/m2 and 0.15. Halophila ovalis takes the minor portion of closure at almost 5%. The water quality parameters measured are temperature, salinity, pH, and current speed ranging from 27 to 3oC, 26 ‰ to 32 ‰, 7 to 8, and 0.20 to 0,46 m/s. In addition, the sandy category dominates the substrates. People utilize the ecosystem for activities such as bameti/balobe, mariculture, fishing, tourism, and boat mooring. Three management directives are formulated to manage the waters. ABSTRAK Penelitian ini berlangsung pada bulan Januari sampai Maret 2021 yang berlokasi pada ekosistem lamun Negeri Amahai Kabupaten Maluku Tengah. Tujuan penelitian ini adalah untuk menganalisis struktur komunitas lamun, mengidentifikasi bentuk-bentuk pemanfaatan ekosistem lamun, dan merumuskan arahan pengelolaan di perairan Negeri Amahai. Pengukuran parameter lingkungan meliputi suhu, salinitas, pH, kecepatan arus dan kondisi substrat. Pengambilan data bentuk-bentuk pemanfaatan lamun dilakukan dengan dua cara yaitu observasi dan wawancara. Arahan pengelolaan dianalisis secara deskriptif yang didasarkan pada hasil penelitian. Berdasarkan hasil penelitian dijumpai enam jenis lamun yaitu Enhalus acoroides, Halophila ovalis, Thalassia hemprichii, Cymodocea rotundata, Halodule pinifolia dan Syringodium isoetifolium. Nilai kerapatan jenis, frekuensi jenis, persentase penutupan jenis tertinggi diwakili oleh jenis Thalassia hemprichii, yaitu 64,22 teg/m2, 0,74, dan 17,77%, sedangkan untuk nilai kerapatan jenis dan frekuensi jenis terendah diwakili oleh jenis Syringodium isoetifolium, yaitu 11,69 teg/m2 dan 0,15. Persentase penutupan terendah diwakili oleh jenis Halophila ovalisdengan nilai 4,48%. Hasil pengukuran parameter lingkungan di perairan Negeri Amahai menunjukkan suhu perairan 27-31oC, salinitas 26‰-32‰, pH 7-8, kecepatan arus 0,20-0,46 m/s, dan kondisi substrat yang dominan adalah berpasir. Bentuk-bentuk pemanfaatan ekosistem Negeri Amahai diantaranya aktivitas bameti/balobe, budidaya laut, penangkapan ikan, wisata dan tambatan perahu. Terdapat tiga arahan yang diformulasikan untuk tujuan pengelolaan perairan Amahai. Kata Kunci: Lamun, struktur komunitas, bentuk pemanfaatan, arahan pengelolaan, Amahai

Abstract

The processing of fruit peel waste into an eco-enzyme is a simple and environmentally friendly technology. This community service program aimed to empower the community through the production of eco-enzyme and eco-enzyme soap in Negeri Hatu. This PKM activity was conducted on May 24, 2025, in Negeri Hatu, Leihitu Barat District, Central Maluku Regency, involving 23 women from the local women's service group. The methods used included lectures and training on the production of eco-enzyme and eco-enzyme soap. Participants were provided with a mini-handbook to facilitate understanding of the material. Subsequently, participants were trained in groups to produce eco-enzyme and eco-enzyme soap. Participant enthusiasm was evident from the various questions raised regarding the eco-enzyme and its benefits. After the activity, participants gained knowledge and understanding of the eco-enzyme and its production process, which they had previously lacked. The results of the activity showed that participants successfully practised the production of eco-enzyme and eco-enzyme soap. It is expected that participants will be able to process fruit peel waste into an eco-enzyme in every household as a concrete step toward reducing organic waste and increasing family economic value.

Abstract

This study aims to identify and analyze the total bacterial count in the seagrass ecosystem of Inner Ambon Bay as part of the microbiological conditions related to anthropogenic activities and pollution levels. It also seeks to determine bacterial species associated with ecological functions in the seagrass ecosystem, thereby providing additional scientific information as a basis for aquatic ecosystem management. Water samples were collected from four different locations, namely Galala Beach, Poka Beach, Tanjung Tiram Beach, and Halong Beach. Physicochemical parameters were measured prior to sampling, and the samples were subsequently analyzed and identified in the laboratory. The results showed variation in total bacterial counts across locations, with the highest value recorded at Galala Beach and the lowest at Halong Beach. Bacterial identification revealed the presence of ten species: Klebsiella aerogenes, Klebsiella pneumoniae, Enterobacter cloacae complex, Enterobacter aerogenes, Serratia odorifera, Citrobacter sp., Pseudomonas aeruginosa, Serratia marcescens, Escherichia coli, and Staphylococcus sp.

Abstract

Sampah organik dapat menimbulkan penyakit, bahkan dapat menyebabkan pemanasan global akibat dari gas metana yang dihasilkan selama proses penguraian. Penanganan sampah organik seharusnya dilakukan dengan konsep ramah lingkungan yaitu diolah menjadi eco enzyme. Eco enzyme merupakan cairan hasil fermentasi sampah kulit buah, gula merah dan air yang dibuat dengan mudah, ramah lingkungan dan tidak mahal. Kegiatan PKM bertujuan untuk mengolah sampah kulit buah pisang menjadi eco enzyme dan sabun eco enzyme. Kegiatan ini berlangsung pada 7 Juni 2025 di Jemaat GPM Sumber Kasih Ambon yang melibatkan 57 orang terdiri dari kaum bapak, ibu dan pemuda gereja. Metode PKM yang diterapkan yaitu ceramah melalui pemberian materi dan tanya jawab serta pelatihan. Dalam pelaksanaan PKM, peserta sangat antusias membuat eco enzyme dan sabun eco enzyme. Berbagai pertanyaan kritis yang ditanyakan dari peserta menunjukan bahwa peserta PKM ingin mengetahui lebih dalam tentang eco enzyme. Kegiatan PKM ini dinyatakan berhasil karena keseluruhan peserta (100%) menjawab telah memahami materi yang diberikan serta mampu membuat eco enzyme dan sabun eco enzyme pada sesi pelatihan.
