Abstract

Masalah sampah laut merupakan masalah lingkungan yang terjadi di Teluk Ambon. Hampir setiap hari terlihat sampah laut mengapung dan menyebar sepanjang perairan pesisir disekitar Kota Ambon. Sampah laut yang berada pada Teluk Ambon, umumnya merupakan sampah dari daratan yang secara sengaja dibuang ke pantai atau ke sungai, dan pada akhirnya akan terbawa oleh aliran sungai ke pantai, sehingga pasang surut dan arus membawa sampah tersebut ke tengah laut. Pola transport sampah laut, pada dasarnya sangat dipengaruhi oleh pola sirkulasi yang terjadi di perairan Teluk Ambon. Tujuan penelitian ini adalah untuk mengetahui kepadatan dan pola transport sampah laut terapung (SLT) di pesisir barat perairan Teluk Ambon Luar (TAL). Metode yang digunakan yaitu metode line transek unutk analisi kepadatan SLT dan metode trajektori untuk mengetahui pola transport SLT. Hasil penelitian menunjukan bahwa Hative 1 merupakan area dengan kepadatan SLT tertinggi dan dominan jenis SLT pada pesisir barat perairan TAL adalah kategori jenis sampah plastic sebesar 93.44%. Pola transport SLT sangat dipengaruhi oleh faktor pasang surut dan tekanan angin.

Abstract

Natsepa Beach is one of the famous tourist areas on Ambon Island. The presence of tourists in the area contributes to the production of both organic and inorganic waste which affects not only the aesthetics of the area but also the income of economic agents. The study aims to analyse waste composition, waste generation, and the recycling potency in Natsepa Beach. The study was conducted from July to August 2022 by applying a field observation method. The procedure of SNI 19-3964-1994, which regards urban waste collection methods to measure the composition and waste generation, was applied in this research. The results showed that the amount of organic waste, which is dominated by fruit peel waste (from rujak or fruit salads), is about 92.21%, whereas it is only about 7.79% of inorganic waste that comes from plastic waste. Total weight of waste that is generated by a person is around 0.12 kg/day or 0.46 liters/day in volume standard. Thus, it can be assumed that every visitor in Natsepa Beach produces 0.12 kg (0,11 kg of organic and 0,01 kg of inorganic waste). The potency to recycle organic waste into compost is 100% and eco enzyme is 78.52%. Furthermore, the potential plastic waste recycling is about 77.19%.

Abstract

Contaminants entering marine systemts have become environmental issues because of their significantly negative impacts. Coasts of Rumah Tiga Village are connected to Ambon Bay and provide marine habitats and tourist attractions due to their location close to Merah Putih Bridge (including recreations, restaurants and aquaculture sites). These human related activities contribute to the discharge of wastes into marine waters. Due to their location at inshore outer Ambon Bay, marine pollutants from the bay tend to be applied at the location. Because of the concentrated pollutants at the location, the coasts of Rumah Tiga Village are a suitable location to conduct beach clean-ups in Ambon Bay. The beach clean-up activities also aim to allow Study Program of Marine Science of Faculty of Fisheries and Marine Sciences, Pattimura University to raise awareness to its students and local community to care for environment.

Abstract

Penanganan limbah merupakan salah satu solusi yang tepat untuk menjawab permasalahan sampah baik yang dilakukan dengan teknologi sederhana, maupun tingkat tinggi. Sampah organik adalah sampah yang paling umum dihasilkan oleh masyarakat setiap harinya sehingga penanganan sampah sederhana yang mudah diimplementasi pada tingkat rumah tangga perlu dilakukan. Salah satu bentuk penanganan adalah melalui pembuatan eco-enzyme. Sebagai kawasan wisata, potensi sampah organik yang dihasilkan di pantai Negeri Suli cukup tinggi karena adanya penjualan kuliner rujak buah dan pisang goreng. Kegiatan PkM ini bertujuan untuk meningkatkan pengetahuan dan keterampilan perempuan Negeri Suli dalam proses pembuatan ecoenzyme sebagai salah satu alternatif bentuk pengolahan limbah organik. Kegiatan dilakukan pada bulan September 2022. Output dari kegiatan ini adalah berupa produk eco-enzyme, sedangkan kegiatan ini bermanfaat meningkatkan ilmu dan keterampilan perempuan Negeri Suli tentang konsep eco-enzyme. Hal ini terindikasi melalui hasil evaluasi yaitu adanya peningkatan pengetahuan tentang konsep ecoenzyme (dari rata-rata 3,85% menjadi 100%). Meskipun belum sampai pada tahap pemasaran, produk ini dapat mengurangi pengeluaran untuk beberapa keperluan rumah tangga, sehingga secara tidak langsung berimplikasi pada perekonomian rumah tangga.

Abstract

Knowledge about waste, pollution, and its impacts is a crucial issue to provide in society, and it is important to instill this in children because their characteristic is easier to build. The impact of pollution will be experienced by any generation whether in a short or long term period. A simple and practical method to manage waste, especially plastic, is by making eco-bricks. It is an easy way to practice. The community service activity aims to introduce marine debris and plastic waste management concept based on eco-bricks for Sunday School students. The activity was carried out on Thursday, April 20, 2023, involving the students from Sunday School Service students which was located in Airlouw Village Ambon. The methods were demonstration, training, lecture, and evaluation by providing questions regarding pollution and how to deal with it. The participants were divided into groups, assigned to complete a scheme of waste fate in the environment from human activities to its effects on waters and humans themselves, trained to handle plastic waste by making eco-bricks, and equipped with knowledge related to types of waste and its degradation process. Although only some participants were familiar with eco-bricks-based waste processing, all participants are easy to implement the process. The accomplishment can be directly measured through the discussion process carried out simultaneously during the training process. All in all, education complemented by material enrichment and schematic assignments can train children’s thinking skills, and practical method for managing waste is weighty for a young age.

Abstract

Pantai merupakan wilayah yang sangat dinamis sebab tekanan yang tinggi dari darat, laut dan udara. Dampaknya adalah kawasan pantai selalu mengalami perubahan secara terus menurus, dimana hal itu dianggap sebagai proses keseimbangan pantai. Tujuan dari penelitian ini adalah menganalisis kemiringan pantai pada perairan pantai barat Pulau Wamar dan menganalisis pola distribusi sedimen dasar pada perairan pantai barat Pulau Wamar. Penelitian dilakukan pada pantai barat Pulau Wamar (Durjela, Wangel dan Pantai Batu Kora) tahun 2017. Data kemiringan lereng pantai diukur langsung dilapang, sedangkan sedimen dilakukan pencuplikan pada 17 transek. Analisis kelas kemiringan lereng pantai didasarkan pada kriteria Zuidam dan analisis sedimen terkait dengan dominansi butiran dan distribusi sedimen berdasarkan analisis statistik. Kelas kemiringan lereng pantai rata-rata berkisar antara landai sampai miring. Sedimen pantai didominasi oleh katagori lumpur sampai kerikil. Kisaran nilai mean berkisar dari kerikil halus (granule) hingga pasir sangat halus, tapi ukuran butiran yang lebih mendominasi adalah pasir sedang, Nilai sorting adalah very well sorted (terpilah sangat baik) hingga very poorly sorted (terpilah sangat buruk), tapi lebih didominasi oleh poorly sorted. Nilai skewness adalah symmetrical, fine skewed dan very coarse skewed. Kurtosisnya lebih didominasi oleh very platykurtic yang artinya pola sebaran yang menunjukkan tendensi pemusatan pada ukuran butiran hampir sama

Abstract

The mangrove ecosystem contributes to climate change mitigation by absorbing carbon dioxide gas. The shoreline of Negeri Waai, Central Maluku Regency (CMR), becomes one of Indonesia's promising mangrove ecosystem habitats for carbon absorption. Therefore, this research aimed to assess the blue carbon potential of mangroves on the coast of Negeri Waai, CMR. This research collected data using the quadrant transect method (10 x 10 m) and placed randomly in 65 quadrants. The analysis of blue carbon potential used an allometric approach to above and below-ground biomass (AGB and BGB). The results showed that the total blue carbon mangrove stock on the coast of Negeri Waai was 73.22 ton C/ha, consisting of 49.44 tons C/ha above-ground carbon (AGC) and 23.78 tons C/ha below-ground carbon (BGC). Sonneratia alba contributed the most extensive carbon stock, namely 70.69 ton C/ha, consisting of 47.53 tons C/ha AGC and 23.16 tons C/ha BGC. This result was relatively low compared to the global average of blue carbon in mangroves, 134 ton C/ha. Based on this result, efforts were needed to restore the mangrove ecosystem, increase the potential for carbon absorption, and mitigate climate change.

Abstract

Hukurila waters have the potential to develop a macro type of algae Porphyra sp. The technique of casting a net that is used as an artificial substrate as a place for sticking spores is interesting to experiment with, which has always only utilized this Porphyra from nature during the eastern season. This activity aims to apply the technique of making artificial subsrats using nets in increasing Porphyra yields. The activity began with the planting of pieces of wood as long poles to tie the net. After the piles have been well embedded then, the net is then opened and tied at every angle from the net to the wooden pole using nylon rope. At the end of this activity, it was seen that there was an understanding of the use of nets as an artificial substrate for pasting Porphyra spores. This activity is very beneficial for the community in increasing the number of crops through the technique of making artificial substrates as a medium for sticking spores during the eastern season

Abstract

Mangrove ecosystem is a type of coastal ecosystem that has many benefits from both ecological, social and economic aspects. The role of mangroves in absorbing carbon reaches 965 tons C/ha. The ability to store carbon is four times more than other ecosystems. Besides absorbing and storing carbon, mangroves also release carbon through litter production. The production of mangrove litter will then experience decomposition resulting in a flux of greenhouse gases. One of the greenhouse gases that triggers climate change is carbon dioxide (CO2). The aim of this research was to determine the concentration and emission values of carbon dioxide (CO2) in the sediments of the mangrove ecosystem of Nania Village, Ambon City. Gas sampling using a syringe through a syringe mounted on a hood. Analysis of gas concentrations used the gas chromatography method. Sediment sampling is carried out using a small shovel on the surface of the substrate under the mangrove canopy. Sediment samples will be analyzed using a sieving process. The results showed that the average concentration of CO2 gas with the highest value in the sandy mud substrate with a value of 701.61 ppm and the lowest in the sand substrate with a value of 561.48 ppm. The largest CO2 gas emission in the mangrove ecosystem sediments of Nania Village was found in the sand sediment type of 75.0535 mg/m2/hour with an emission value, and the lowest was found in mud sediments, namely 30.1899 mg/m2/hour.
