Abstract

Mangrove litter production is important in the displacement of organic matter from mangrove vegetation to water such as in the coast of West Muna Regency. However, one factor influencing it is the frequency of rainfall. This research, therefore, aims to determine the influence of the frequency of rainfall in mangrove ecosystem by obtaining data through the fractional wet weight. The results showed that the biomass fraction with the largest amount were Rhizophora mucronata, Rhizophora apiculata, and Sonneratia alba with of 31.59; 31.07; and 30.96%, respectively, while the lowest was Rhizophora stylosa, Bruguiera cylindrica, and Bruguiera gymnorrhiza with of 30.07; 30.10; and 31.95%, respectively. The species with the largest leaf litter production was Bruguiera cylindrica, with of 1.72 g.m-2.day-1 which occurred in April and the lowest was Rhizophora apiculata, 0.24 g.m-2.day-1 in August. The species with the largest leaf litter production was Bruguiera cylindrica, 1.96 g.m-2.day-1 which occurred in May and the lowest was Sonneratia alba, 0.29 g.m-2.day-1 in August. In addition, the species with the largest fruit litter production was Rhizophora apiculata, 1.76 g.m-2.day-1 in April and the lowest was Sonneratia alba, 0.32 g.m-2.day-1 in September. The total litter production was 18,75 g.m-2.day-1 consisted of 6,69 g.m2.day-1 leaf litter, 6,54 g.m-2.day-1 branch litter, and 5,52 g.m-2.day-1 fruit litter. The higher the frequency of the rain, the greater the litter production. Keywords: biomass fraction, seasonal litter production, West Muna Regency

Abstract

Mangrove ecosystem is valuable coastal ecosystems for human because its economic, physical and ecological functions. One of the coastal areas which is the habitat of the mangove ecosystem is the coast of West Muna Regency. The coastal development in the coastal area had reduced the mangrove area and the density of mangrove ecosystem, which in turn affected the structure and density status of the ecosystem. The number of mangrove species in the coast of West Muna Regency was ten species consisting of Bruguiera cylindrica, Bruguiera gymnorrhiza, Rhizophora mucronata, Rhizophora apiculata, Rhizophora stylosa, Sonneratia alba, Xylocarpus granatum, Ceriops tagal, Scyphiphora hydrophyllacea, and Calophyllum inophyllum. The total density of mangrove was 752 trees/ha, however, by seeing in detail through each sampling station the density of Station I, II, III and IV was 879, 621, 687 and 820 trees/ha, respectively. Those densities are categorized as low density.

Abstract

One of the ecological functions of mangroves ecosystem is to store carbon. Yet, on the other hand it also has the potential to cause greenhouse gas emissions through litter degradation even though its value is lower compared to the absorption value. Based on these two facts, mangrove management as a Green Open Space in the Tallo river area of ​​Makassar City needs to consider involving the participation of the community and the government as stakeholders. The research was conducted by desk work, literature study and respondent interviews regarding perceptions and participation in mangrove management. The results showed that the total uptake of mangrove carbon in the Tallo river in Makassar city was 351.02 tons CO2/ha, oxygen supply 255.29 O2-equivalent/ha, and the potential for global warming was 252.41 mg/ m2/hour consisting of 194, 33 mg/m2/hour of CO2 gas, 15.76 mg/m2/hour of CH4 gas, and 42.33 mg/m2/hour of N2O gas. The results of community perception and participation analysis show that around 89% of the community strongly agreed and supported the government in the effort to manage mangroves as a green open space. Based on this, the ecosystem in the Tallo river is very suitable to be managed for green open space as fresh air supplier and CO2 adsorber as well as a noise reduction from vehicle or industrial engines in Makassar city.

Abstract

This research was conducted to analyze the root causes of poverty with a socio-ecological system approach. The analytical method used the Socio-Ecological System analysis based on the Burkhard Model and Spidergram Approach. The analysis results showed that aquaculture activities in ponds had a high relationship with ecological integrity. Aquaculture activities were carried out by converting mangroves so that they put pressure on the ecological system. The pressure on ecological systems impacted social systems due to the magnitude of connectivity. Besides, the pressure on the social system was indicated by a decrease in daily income for farmers due to reduced catch from wild shrimp, as well as a decrease in catch and an increase in fishermen's operational costs due to further distance fishing grounds. For the reasons, it was necessary to enforce the rules of spatial use that were parallel with improving the quality of the ecosystem and the coastal environment, as well as fostering recommended technology and community empowerment that was expected to help increase the income of coastal communities. Furthermore, through the provision of adequate educational, health, and religious facilities, thus it could improve the community welfare so that they leave out from poverty problems.

Abstract

Studies on the fluxes of greenhouse gases in mangrove ecosystems especially during tides are relatively scarce. The research was conducted in Tallo River Makassar which is a mangrove ecosystem habitat. Gas sampling was done by utilising size 0,5x0,5x1 m3 chamber through a syringe during the tidal periods. Gas analysis was done using gas chromatography methods. The research shows that the flux of CO2 gasduring high tide was 204,84 mg m-2 hr-1 or 1,79 kg m-2 year-1  and 183,81 mg m-2 hr-1 or 1,61 kg m-2 year-1 during low tide, while the flux of CH4 gaswas 0,75 mg m-2 hr-1 or 0,007 kg m-2 year-1  during high tide and 0,62 mg m-2 hr-1 or 0,005 kg m-2 year-1 during low tide, and the flux of N2O gaswas 0,141 mg m-2 hr-1 or 0,0012 kg m-2 year-1  during high tide and 0,145 mg m-2 hr-1 or 0,0013 kg m-2 year-1  during low tide.

Abstract

Penelitian tentang estimasi dan model pendugaan biomassa pada tegakan pohon mangrove telah banyak dilakukan baik dalam tingkat ekosistem maupun spesies, namun belum pernah dilakukan pada spesies Nypa fruticans. Penelitian ini bertujuan untuk membuat sebuah model penduga nlilai biomassa Nypa fruticans di Sungai Tallo yang terdapat di Makassar-Indonesia yang merupakan salah satu habitat mangrove. Pendugaan biomassa dilakukan dengan menebang mangrove sebanyak 15 pohon pada range diameter terbesar hingga terkecil. Biomassa dihitung berdasarkan berat kering yang diperoleh dari pengeringan sub contoh berat basah pada suhu 130 ⁰C selama 48 jam. Analisis model penduga biomassa menggunakan regresi linier dan model allometrik yang akan menyatakan hubungan antara diameter pangkal atau pelepah dengan nilai biomassa mangrove. Hasil analisis menunjukkan bahwa model penduga biomassa Nypa fruticansbersifat allometrik yang berkorelasi dengan diameter pangkal dan diameter pelepah yaitu B = 0,098(DB)1,4934  dan B = 0,222(DS)2,7048 dan lebih baik dibandingkan model analisis regresi. Total biomassa Nypa fruticans menurut diameter pangkal dan pelepah yakni 174574,4kgatau 40132, 69 kg/ha dan 173959,4kg atau 39991, 32 kg/ha.

Abstract

Ekosistem mangrove di Kecamatan Maginti memberikan manfaat jasa ekosistem yang besar kepada manusia. Penelitian ini bertujuan untuk menganalisis supply – demand jasa ekosistem mangrove di Kecamatan Maginti. Penelitian dilakukan melalui observasi, wawancara, dan studi literatur. Analisis data jasa ekosistem dilakukan dengan mengadopsi matriks penilaian dari model Burkhard yaitu jasa penyedia, jasa pengaturan, jasa budaya, dan jasa pendukung. Hasil penelitian menunjukkan bahwa terdapat 25 jasa ekosistem di Kecamatan Maginti yang terdiri dari 11 jasa penyedia, 7 jasa pengaturan, 2 jasa budaya, dan 5 jasa pendukung. Kapasitas jasa penyedia yang sangat tinggi terdapat pada kolom perairan sebagai penghasil ikan, udang, dan kepiting. Kapasitas jasa pengaturan yang sangat tinggi terdapat pada tegakan pohon mangrove terutama sebagai perangkap sedimen, penahan arus dan gelombang, penahan angin kencang, dan penyerap karbon. Kapasitas jasa budaya sebagai tempat rekreasi terdapat pada substrat pasir dengan kapasitas sedang, dan fraksi buah dengan kapasitas sangat tinggi. Sebagian besar jasa ekosistem mangrove memiliki surplus karena kapasitas jasa yang tersedia melebihi permintaan. Defisit jasa ekosistem terdapat pada keterbatasan lahan pemukiman yang menyebabkan terjadinya degradasi mangrove sehingga memerlukan penanggulangan melalui rehabilitasi lahan – lahan tambak nonproduktif.

Abstract

Acts of domestic violence can happen to anyone, but only a small portion emerges to the surface, while some are still submerged or unrecognized. This condition is influenced by the community's opinion that domestic violence is an internal family problem and should not be exposed, some people still cover up this condition because they maintain social status for them. Family unity and harmony can be disrupted if quality and self-control cannot be controlled, which can eventually lead to domestic violence resulting in a sense of insecurity, discomfort and injustice in the household. Cases of domestic violence show a trend that continues to increase from year to year. The purpose of implementing the activity is to increase awareness of the importance of the mental health of victims of domestic violence in Latuhalat Country. Besides that, the goal of this socialization is that the public knows the forms of domestic violence, the cycle of domestic violence, the impacts of domestic violence and how to overcome them.

Abstract

Mangrove ecosystems have potential both ecologically, economically, physically, and chemically. The abundance of this potential causes pressure from anthropogenic activities, which results in the degradation of mangrove ecosystems. Several mangrove ecosystems in the Ambon City area have experienced degradation, so restoration is necessary. The Passo State area has the potential for a dense mangrove ecosystem and can be used as a nursery area to support other ecosystems. Increasing the potential of mangrove ecosystems in the Passo State area can be done through restoration using biodegradable materials (BESE-Elements). Mangrove restoration is carried out through community service activities, a collaboration between the Maritime Center and Wardeen Burg Ecology – The Netherlands. The result of the activity is that mangrove ecosystem restoration is carried out in semi-enclosed areas using 10 BESE-Element. Each BESE-Element was planted with 10 mangrove seedlings consisting of 5 seedlings and 5 propagules. The mangrove species planted were Bruguiera gymnorrhiza, Rhizophora apicutala, and Rhizophora stylosa. Around BESE-Elements planted seedlings and mangrove propagules as a control for mangroves in BESE-Elements.
