Abstract

Rawa Pening is a semi natural lake which is utilized for hydro-electric power plant,  caged fish culture, irrigation, and tourism. It belongs to one of the fifteen lakes which receives national priority to be saved and preserved because of its very poor condition as a result of eutrophication, sedimentation and degraded water quality. Eutrophication of  Rawa  Pening comes from the Water Catchment Area,  originating from farms, animal husbandry, domestic and industrial waste around the lake, and also from the water body itself, that is from caged fish culture. The fertility criteria of the lake water can be determined on the basis of the abundance and variety of phytoplankton and the total phosphorus content. The aim of this research is to find out the water fertility criteria of Lake Rawa Pening based on the abundance and variety of  phytoplankton, and the phosphorus content. Research began in July 2012 on three stations. Station I is an area with fishcage culture;  Station II is an area without fishcage culture, and Station III is the river inlet or water catchment area. Each station consisted of three different sampling areas. The phytoplankton abundance at the station without  fishcage culture is higher  (19012 ind/l) than at the fishcage culture station (14356 ind/l)  as well as at the inlet station (11058 ind/l), but the diversity index at the no fishcage station is lowest (1.80)  compared to the fishcage culture station (2.32)  and the inlet station (2.05). The fertility criteria of Rawa Pening based on the phytoplankton abundance and P-total  of  its water is eutrophic  going  towards  hypereutrophic.   Keywords : Lake Rawa Pening, Phosphorus, Water Quality, Euthropication

Abstract

Periphyton abudance is influenced by water dynamics like a currents and waves. The aim of the research was to determaine periphyton abudance on Thallasia hemperichii seagrass in different season waters at Legon Boyo, Karimunjawa. The result show in T. hemperichii were found 9 periphyton classes. The most number is Bacillaryophyceae dominant in every season. Biology index show a value of 0.96-2.6 (low-moderate diversity), uniformity has a value of 0.65-1.48 (medium-high uniformity) and dominance with a value of 0.11-0.23 (low dominance). This shows that the abundance of different periphyton is caused by differences in water dynamics in each season.

Abstract

Banjaran River is a river that is widely used by local people for their daily needs, including for bathing, drinking water, washing, and irrigation of agricultural land. These activities will cause changes in the quality of the waters of the Banjaran River so that it will cause water pollution, especially pollution from organic materials. This pollution will cause changes in the structure of the biota community, one of which is the phytoplankton in the Banjaran River. Phytoplankton are organisms that play a role in providing nutrients and maintaining the balance of aquatic ecosystems. The purpose of this study was to determine the structure of the phytoplankton community in the Banjaran River, Banyumas Regency. The method used in this research is purposive sampling, with 4 sampling points and 3 repetitions. Sampling was carried out in April-May 2021 with an interval of 2 weeks. Data analysis in this study includes the calculation of abundance, diversity index, and phytoplankton dominance index. The results showed that the abundance of phytoplankton in the Banjaran River was 453-720 individuals.L-1, the diversity index was 1.97-2.25, and the dominance index was 0.13-0.18. These results indicate that the structure of the phytoplankton community in the Banjaran River is in moderate diversity and there is no particular species that dominates in these rivers.Keywords: Phytoplankton, Banjaran River, Aquatic Ecosystem.

Abstract

Biofouling refers to the attachment of organisms to the surface of an object submerged in water. It is often undesirable due to its detrimental effects, meanwhile, one way of managing biofouling is via antifouling. This study aims to examine the potential of kenikir (Cosmos caudatus) and bandotan (Ageratum conyzoides) leaves extracts as an alternative to natural antifouling. The research was conducted using the exploration method where the extract of both plants was examined in field and laboratory scales. Moreover, the extracts were mixed with paint without antifouling and then tested on a field scale by painting on wooden blocks. Observations were made by counting the number of microfouling in form of bacterial colonies attached to the painted wood surface by scraping the surface of the wood submerged in freshwater for one week. The results showed that the number of bacterial colonies with kenikir leaves extract was less than the bandotan extract. Moreover, based on the phytochemical analysis results, both kenikir and bandotan extracts contain alkaloids, steroids, tannins and saponins, however, the alkaloid content in kenikir leaf extract was higher compared to bandotan leaves. In conclusion, kenikir leaves extract has greater potential as an alternative source of antifouling compared to bandotan because the former has more bioactive content, especially alkaloid compounds.

Abstract

Nitrat, nitrit, amonia dan fosfat merupakan salah satu indikator kesuburan dan kesehatan lingkungan. Keberadaan aktivitas antropologi seperti Tempat Pelelangan Ikan, pertambakan dan wisata bahari diduga mempengaruhi konsentrasi unsur hara di perairan tersebut. Penelitian ini bertujuan untuk mengetahui konsentrasi unsur nitrat, nitrit, amonia dan fosfat di Perairan Munjung Agung. Penelitian dilakukan dengan menggunakan metode deskriptif. Penelitian dilakukan pada bulan september-november 2021. Analisis data yang digunakan adalah analisis kesesuaian ambang baku mutu yang dilakukan dengan membandingkan nilai sampel yang diperoleh dengan ambang baku mutu perairan berdasarkan Keputusan Menteri LHK No 51 Th 2004 tentang Ambang Baku Mutu Perairan. serta analisis determinasi tingkat pencemaran menggunakan metode STORET (Keputusan Menteri LHK No 115 Th 2003). Hasil penelitian dapat disimpulkan bahwa nilai nitrat, nitrit, amonia dan fosfat di Perairan Munjung Agung tidak memenuhi ambang baku mutu sesuai dengan Keputusan Menteri LHK No 51 Th 2004. Konsentrasi nitrat berkisar antara 1,21-3,80 mg/l, nitrit berkisar antara 0,01-0,35 mg/l, amonia berkisar antara 0,21-0,33 mg/l dan fosfat berkisar antara 0,12-0,22 mg/l. Nilai determinasi pencemaran di perairan masuk dalam kategori tercemar sedang-berat dengan nilai -26 s/d -32. Kondisi ini disebabkan karena aktivitas antropologi disekitar perairan tinggi, dimana digunakan sebagai lokasi tempat Pelelangan Ikan, pertambakan hingga wisata bahari.     Nitrate, nitrite, ammonia and phosphate are indicators of fertility and water health. Anthropological activities such as fish auction sites, aquaculture and marine tourism are thought to have determined the concentration of water nutrients. This study aims to determine the concentration of nitrate, nitrite, ammonia and phosphate in Munjung Agung waters. The research was conducted using descriptive method. The research was conducted in September-November 2021. Data analysis used analysis of the suitability of the quality standard threshold, which is carried out by comparing the sample value obtained with the water quality standard threshold based on the Decree of the Minister of Environment and Forestry No. 51 of 2004 and the analysis of the determination of the level of pollution used the STORET method (Decree of the Minister of Environment and Forestry, No. 115 of 2003). The results of the study were that the values of nitrate, nitrite, ammonia and phosphate in Munjung Agung waters did not meet the quality standard threshold in accordance with the Decree of the Minister of Environment and Forestry No. 51 of 2004. The concentration of nitrate ranged from 1.21-3.80 mg/l, nitrite ranged from 0.01-0.35 mg/l, ammonia ranged from 0.21-0.33 mg/l and phosphate ranged from 0.12-0.22 mg/l. The determination of water pollution value is categorized as moderately-severely polluted with a value of -26 to -32. This condition is caused by anthropological activities around the high waters, which are used as locations for fish auctions, aquaculture and marine tourism.

Abstract

Mangrove memiliki peran sebagai pendaur unsur hara dan penyerap karbon. Karbon tersimpan pada sedimen mangrove diduga memiliki konsentrasi berbeda pada setiap jenis mangrove dan zonasi mangrove. Penelitian ini bertujuan untuk mengetahui karbon organik pada sedimen mangrove berdasarkan tingkat kerapatan dan jenis mangrove yang berbeda. Penelitian dilakukan di Kawasan Ekosistem Esensial (KEE) Mangrove, Muara kali Ijo, Kebumen. Kegiatan penelitian dilakukan pada Bulan Juni-Juli Tahun 2022. Penelitian dilakukan pada 3 stasiun dengan masing-masing stasiun terdapat 3 plot. Materi yang digunakan dalam penelitian ini adalah sampel karbon organik pada sedimen mangrove serta data kerapatan mangrove yang berada di Muara kali Ijo, Kebumen. Analisis data menggunakan metode kerapatan dan analisis karbon menggunakan metode LOI (loss on ignition). Mangrove di Muara Kali Ijo, Kebumen memiliki kerapatan jarang hingga sangat padat dengan rentang nilai 1,64%-100% dari jenis kerapatan jarang hingga sangat padat 97,92 % dengan kerapatan sebesar 20 ind/ha-1.880 ind/ha. Nilai karbon organik pada sedimen berdasarkan stasiun menunjukkan bahwa karbon organik tertinggi pada stasiun 1 dengan nilai sebesar 1,68 mg/l dan terendah pada stasiun 3 dengan nilai 1,63 mg/l. Hal ini menunjukkan bahwa semakin tinggi kerapatan mangrove maka karbon tersimpan akan semakin tinggi, sehingga mangrove perlu dikelola dengan baik sebagai salah satu sumber karbon organik di perairan. Mangroves have a role as a nutrient recycler and carbon sink. Carbon stored in mangrove sediments is suspected to have a different concentration in each type of mangrove and mangrove zonation. This study aims to determine the carbon stored in mangrove sediments based on the density level and different types of mangroves. The research was conducted in the Mangrove Essential Ecosystem Area (KEE), Muara Kali Ijo, Kebumen. This study aims to determine the organic carbon in mangrove sediments based on the density level and different types of mangroves. The research was conducted in the Mangrove Essential Ecosystem Area (KEE), Kali Ijo Estuary, Kebumen. The research was conducted in June-July 2022. The research have 3 and every station have 3 stasiun plots. The material used organic carbon samples from mangrove sediments and mangrove density from Kali Ijo Estuary, Kebumen. Data analysis used the density method and carbon analysis used the LOI (loss on ignition). The mangrove estuary of Kali Ijo, Kebumen has a density of rare to very dense with a value range of 1.64%-100% from rare to very dense density of 97.92% with a density of 20 ind/ha-1,880 ind/ha. The results showed that the density was rare to very dense with a value of 1.64%-100% of the rare to very dense density of 97.92% with a density of 20 ind/ha-1,880 ind/ha. Organic carbon values in sediment based on stations showed that the highest organic carbon was at station 1 with a value of 1.68 mg/l and the lowest was at station 3 with a value of 1.63 mg/l. The value of organic carbon is higher at high mangrove density, so mangroves need to be managed properly as a source of organic carbon in the waters.

Abstract

Kebumen Village is a village in Baturraden District, Banyumas Regency, Central Java. The average head of family in this village is a laborer, so the family's economy was affected during the Covid-19 pandemic. So far, many residents in Kebumen Village do not yet have the skills or expertise that can become capital for entrepreneurship. However, the obstacles experienced were that there were no facilitators who provided business skills during the pandemic and there was no budget from village funds. Much of the village budget has been absorbed for the handling of Covid-19. The purpose of this activity is to provide business skills assistance for Kebumen Village PKK Cadres through training activities in making fish nuggets. Community service activities in Kebumen Village as an effort to improve the community's economy during the Covid-19 pandemic. The method of implementing the activity is Participatory Rural Appraisal (PRA), namely by directly practicing making fish nuggets, starting from mincing the meat, mixing the ingredients to make the nugget dough, steaming, cutting the dough, coating the dough with panir flour, to frying the nuggets ready to eat. In addition, participants were also asked to fill out a questionnaire regarding this community service activity. The results of the training activities are increasing the knowledge and skills of PKK cadres in processing modern fish products, as well as generating creative ideas to create business opportunities that are useful for increasing family income during the Covid-19 pandemic. Based on the data from the questionnaire results, it was found that all training participants benefited from the fish nugget making training. The training provided by the community service team to PKK Cadres in Kebumen Village, Baturraden District was considered very useful in increasing knowledge in processing freshwater fish into modern snacks that are worth selling. Participants were very enthusiastic in participating in the entire series of fish nugget making training activities and revealed that this activity could be an idea for doing business in the post-Covid-19 pandemic.

Abstract

Plastic waste pollution has become one of the central issues of society in Indonesia, considering the various negative impacts on the environment, economy, safety, and health arising from the presence of this waste. Therefore, the Government of Indonesia has established policies to improve the performance of reducing household and household-like waste through various strategies. One of these strategies is the recycling and reuse of household waste and formal and informal education. This activity was carried out to provide education on the importance of protecting the environment and managing waste for the people of Karanggintung Village. In addition, providing training on making handicrafts made from plastic is an effort to manage waste. Activities are carried out with the stages of preparation for activities, counseling, implementation of training, and ending with activity evaluation. The training is carried out using the demonstration method carried out by a team of partners, lecturers, and students with a participatory approach that involves the community being actively involved in all activities. The activity was prepared by compiling an activity plan followed by coordinating with the Banyumas Regency Environmental Service (DLH) and the Karanggintung Village Head and his staff. After that, counseling was carried out about the importance of processing plastic waste to the public about the potential for plastic waste to enter the sea so that it is harmful to marine organisms. The next stage is training on processing plastic waste into various handicraft products, which is attended by community cadres who are expected to become a driving force for other communities. The training was carried out by demonstrating the manufacture of handicraft products made from plastic. After that, the participants practiced with the team. Handling plastic waste is very important to keep the environment clean. This can be done by recycling plastic waste into handicrafts.
