Abstract

Perairan selatan Jawa merupakan bagian dari perairan samudera Hindia yang memiliki arus besar yang disebut Arus Khatulistiwa Selatan (AKS) yang sepanjang tahun menuju ke arah barat dan menyebar dari barat laut Australia menuju sisi lain dari samudera Hindia. Dinamika oseanografi perairan timur Samudera Hindia sangat dipengaruhi oleh keterkaitan yang kompleks. Penelitian ini bertujuan untuk menganalisis kondisi sebaran menegak dan melintang medan massa, tekanan dan arus geostropik perairan selatan Jawa. Penelitian ini menggunakan data World Ocean Atlas (WOA) hasil penginderaan jarak jauh bulan Agustus tahun 2009. Hasil penelitian yang diperoleh menunjukkan perairan selatan Jawa merupakan bagian dari perairan samudera Hindia yang memiliki arus besar yang disebut Arus Khatulistiwa Selatan (AKS) yang sepanjang tahun menuju ke arah barat dan menyebar dari barat laut Australia menuju sisi lain dari samudera Hindia. Apabila aliran AKS bergerak semakin cepat sepanjang pantai selatan Jawa-Sumbawa, maka akan mengakibatkan massa air akan menumpuk di belahan bumi selatan yang merupakan bagian sisi lepas pantai. Hal ini mengakibatkan bagian lepas pantai (yang menjauh dari pantai)  memiliki kedalaman dinamik yang lebih tinggi dari bagian yang lebih dekat atau berada di sisi pantai, sehingga arus geostropik yang mengalir pada wilayah tersebut akan mengalir dan dibelokan ke arah barat.

Abstract

Mangrove restoration is really needed for restoring its ecosystem functions, so that it could be able to support fisheries activity and to protect coastal by extreme weather. In addition, mangrove is able to accumulate sediment that important in protecting the coastal area from sea level rise. Therefore,  the aim of this study is to investigate sediment accumulation rate in mangrove area during post restoration. Sampling location were divided into three different stations based on estimated restoration ages, such as ≥ 15  years old (Station 1), 4 - 10 years old (Station 2) and 2 - 8 years old (Station 3). Sediment cores were carried out by inserting 7.6 cm diameter and 100 cm length of polyvinyl chloride pipes. Sedimentation rate is measured by using Pb-210 radionuclide analysis. The results show that the sediment accumulation rate in the last 20th years from all station ranges from 0.17 to 0.42 g/cm2/year. The highest accumulation rate is found at oldest year old station while the lowest accumulation rate is found at younger year old station of mangrove restoration area. Restoration process is clearly able to recover the mangrove’s role in trapping sediment in coastal region. Keywords: sediment accumulation, mangrove restoration, Lembar Bay-                   Lombok Island

Abstract

The condition of the Mahakam Delta area, especially the coastal region of Kuala Samboja, Kutai Kartanegara Regency has been decreased due to coastal abrasion and several human activities. As a result, several ecological and economic functions of the mangrove ecosystem on the coast of Kuala Samboja have been dropped. One of the alternative activities carried out by individuals and groups to protect and improve the coastal environment of Kuala Samboja due to the impact of coastal abrasion and human activities is to plant mangrove seedlings. The purpose of this community service activity was to increase knowledge, awareness and concern by academics and students towards the preservation of the coastal environment in Kutai Kartanegara Regency by planting Rizophora mucronata seeds. The mangrove seedling planting activity was carried out on May 30, 2022 in Kuala Samboja Village, Kutai Kartanegara Regency after the student practical course activities were completed. The method used in this activity is a lecture followed by demonstration activities for planting mangrove seedlings for the participants. The result of this community service activity was the planting of 400 seeds of Rizophora mucronata in areas affected by human exploitation and abrasion in the village of Kuala Samboja. The beach clean-up activities have been carried out by the participants around the planting of mangrove seedlings in order to maintain the cleanliness of the coastal environment by collecting various types of garbage scattered around the beach. Several evaluations of activities from the participants were found from the results of mangrove seedling activities, such as the maintenance process, data collection, and monitoring of mangrove seedlings that may need to be carried out by the participants. Therefore, an evaluation of this activity should be carried out by the activity participants to make the successful planting of mangrove seedlings. In general, the planting of mangrove seedlings may increase the knowledge, awareness and concern of the participants for the mangrove ecosystem in Kuala Samboja village. In addition, the collaboration between lecturers, local government and local communities during the planting of mangrove seedlings on the coast of Kuala Samboja village might preserve the mangrove ecosystem in a sustainable manner.

Abstract

Coastal areas are characterized by complex dynamics between freshwater entering through the estuary from land and seawater from open water. This study aims to calculate the salinity anomaly found on the sandy coast of Mayang, estimate the number of fractions and the volume of mass transport of fresh water entering the waters through the river flow and measure the total dissolved solids (TDS) in the west season. Water mass characteristics data collection using Water Checker. The determination of 17 data collection stations is assumed to be representative in representing the overall condition of the research location. The results of the anomaly salinity calculation show the low anomalous salinity values that are distributed horizontally on the coast. The distribution of salinity as anomaly values transversely on lines 1 to 4 ranges from -1 to -15. Freshwater fraction is concentrated as far as 1.16 km from the coast of Pasir Mayang with concentration values ranging from 0.44% to 0.13%. The mass transport of fresh water in the Pasir Mayang coastal waters is 1,130 m3s -1. The value of the transport volume of fresh water depends on rainfall and the flow of fresh water through rivers and then into sea waters. The total dissolved solids at the study site at each station ranged from 7.88 ppm to 17.8 ppm.

Abstract

Currently, the people in Desa Jembayan Dalam have only been trained about processing organic waste based on the concept of composting. However, the practice had not been sustained due to wasting time in the process of composting organic waste to become a usable product. The knowledge of the people in Desa Jembayan Dalam on organic waste management is still limited. This community service activity aimed to introduce people about the application of organic waste treatment by using black soldier fly (BSF) larvae and to foster the interest of people in processing organic waste using BSF larvae/maggots. The activity was held in Jembayan Dalam Village on July 14, in the form of capacity building through a socialization event about maggot BSF. Participants were given an understanding of the BSF life cycle, the cultivation process of BSF maggots, the types of organic waste as larvae feed, and the by-product produced at the end of the larvae treatment process. The event was attended by 25 people from Dusun Lembonang, Desa Jembayan Dalam. Six participants were interested in rearing BSF eggs that had been provided. There were six participants who tried to raise the BSF maggot from the eggs of BSF maggot that had been provided. However, only one participant succeeded in raising it for two weeks. The type of organic waste that she used was waste from onion skin and vegetables that already decaying. The length of the BSF maggot that was successfully maintained reached 2 cm. Most participants showed interest in BSF maggot cultivation because of its role in reducing organic waste and its products that can be used as poultry feed. Limited free time owned by the people in the village is an obstacle for them to practice BSF maggot cultivation.

Abstract

ABSTRAKEkosistem mangrove mempunyai fungsi yang sangat penting karena memiliki fungsi fisik dan ekologis. Mangrove adalah satu di antara ekosistem produktif yang produksi primernya terdiri dari serasah, dekomposisi dan nutrisi. Tingginya produktivitas mangrove akan terkait dengan rantai makanan yang bergantung pada serasah yang terurai. Penelitian ini bertujuan untuk mengetahui hubungan kerapatan mangrove dengan laju produksi serasah di kawasan Muara Badak Kutai Kartanegara Kalimantan Timur. Penelitian ini telah dilaksanakan pada bulan Juli – Agustus 2022. Data kerapatan dan produksi serasah mangrove diambil pada transek berukuran 10 m2. Serasah mangrove diambil pada 2 stasiun penelitian menggunakan litter-trap dengan ukuran 1x1 meter selama 1 bulan dengan pengambilan sampel sebanyak 3 kali setiap selang waktu 10 hari. Hasil penelitian menunjukkan jenis mangrove yang dominan ditemukan pada 2 stasiun penelitian yaitu Sonneratia alba, Rhizophora mucronata, Rhizophora apiculata, dan Avicennia marina. Sementara itu, kerapatan mangrove pada pada stasiun I rata-rata sebesar 1.100 ind/ha dan stasiun II sebesar 1.133 ind/ha. Laju produksi serasah mangrove pada stasiun I rata-rata sebesar 0,74 g/m²/hari dan pada stasiun II sebesar 1,64 g/m²/hari. Hasil uji korelasi menggunakan regresi linear menunjukkan bahwa terdapat korelasi yang kuat antara kerapatan mangrove dengan laju produksi serasah.Kata Kunci: Kerapatan mangrove, Muara Badak, produksi serasah.ABSTRACTThe mangrove ecosystem has a very important function because it has physical and ecological functions. Mangroves are one of the productive ecosystems whose primary production consists of litter, decomposition and nutrients. The high productivity of mangroves will be related to the food chain that depends on decomposed litter. This study aims to determine the relationship between mangrove density and litter production rate in the Muara Badak Kutai Kartanegara area, East Kalimantan. This research was carried out in July – August 2022. Data on mangrove litter density and production were taken on a 10 m2 transect. Mangrove litter was taken at 2 research stations using a 1x1 meter litter trap for 1 month with 3 samples taken every 10 days. The results showed that the dominant mangrove species were found at 2 research stations, namely Sonneratia alba, Rhizophora mucronata, Rhizophora apiculata, and Avicennia marina. Meanwhile, the density of mangroves at the station I averaged 1,100 ind/ha, and at station II was 1,133 ind/ha. The production rate of mangrove litter at station I was an average of 0.74 g/m²/day and at station II it was 1.64 g/m²/day. The results of the correlation test using linear regression showed that there was a strong correlation between mangrove density and litter production rate.Keywords: Litter production, Muara Badak, mangrove density

Abstract

Informasi mengenai stok karbon di sedimen ekosistem lamun di Indonesia masih sedikit, khususnya di Kalimantan Timur. Penelitian ini bertujuan untuk mengestimasi stok karbon organik pada sedimen lamun yang berada di perairan sekitar Desa Selangan, pesisir Bontang. Pengambilan sampel sedimen dilakukan pada bulan September 2021, dengan menggunakan pipa PVC yang berdiameter 7 cm dengan panjang 130 cm. Pengambilan sampel sedimen berjumlah 3 core dimulai dari titik lamun yang berdekatan dengan ekosistem mangrove ke arah laut dengan jarak 50 m antar stasiun. Konsentrasi karbon organik sedimen diukur menggunakan metode loss on ignition (LOI) yang dilakukan di Laboratorium Botani Pusat Riset Oseanografi BRIN. Hasil penelitian menunjukkan konsentrasi karbon organik pada lokasi penelitian berkisar 1,70-4,90% dengan nilai rata-rata sebesar 2,72 ±0,20 %. Estimasi stok karbon sedimen lamun yang terdapat di perairan sekitar Desa Selangan adalah 210,94 Mg C/ha. Tidak terdapat perbedaan signifikan pada konsentrasi dan stok karbon organik antar lapisan sedimen. Namun, kedua nilai tersebut cenderung rendah pada lokasi lamun yang berada jauh dari ekosistem mangrove. The available information on sediment organic carbon stock data of the seagrass ecosystem in Indonesia is limited, especially in East Kalimantan. This study aimed to estimate the concentration and stock of organic carbon in seagrass sediment in Selangan, a coastal area of Bontang. Field activities to collect sediment samples were done in September 2021 by using 7-diameter PVC tube core with 130 cm length. Three sediment cores were collected from seagrass adjacent to mangrove ecosystem with 50 m interval between the cores toward the sea. Organic carbon concentration in sediment measured by using loss on ignition method that was performed in Botanical Laboratory of Research Center for Oceanography BRIN. The results showed that the concentration of organic carbon at the study sites ranged from 1.70-4.90% with average at 2.72 ±0.20%. Organic carbon stocks in seagrass sediments in Selangan were estimated at 210.94 Mg C/ha. Both sediment organic carbon concentration and storage values were no significant difference through the layer of sediments. However, both values tend to low in seagrass sediment which were far from mangrove ecosystem.
