Abstract

Lubuk Kertang Village has the potential for mangrove ecotourism which is currently being developed as a source of income for the community's economy apart from fishermen and agriculture. Even the mangrove ecosystem in Lubuk Kertang Village has become a tourist icon for Langkat. Apart from mangrove ecotourism, Lubuk Kertang is also unique with its processed mangrove products in the form of foods such as mangrove dodol, jeruju crackers, and mangrove syrup. However, productivity is constrained by the availability of mangrove fruit which depends on the season. Moving on from this, it is necessary to carry out community service activities to provide education about the potential and benefits of mangrove waste in the form of stems, twigs, leaves, and fruit from other aspects. Namely that apart from being processed as food material, mangrove waste can also be processed into other high-value products, one of which is a natural dye. Activities carried out are in the form of socialization and education about the potential and benefits of mangrove waste as a natural coloring agent to the manufacturing process. Furthermore, the natural dyes that have been produced are applied in the coloring process through the ecoprint workshop/training. The media used are cloth/textiles, paper, sheepskin, and ceramics (mugs). The response of the community, represented by women from independent women farmer groups as well as some students of Madrasah Tsanawiyah and the Village Head was very good. Even some mothers from independent women farmer groups routinely continue to make ecoprints in the form of cloth, pashmina, and t-shirts. Their products have also been included in exhibition activities in Lubuk Kertang Village. The Head of Lubuk Kertang Village hopes that there will be sustainability from independent women farmer groups to make ecoprint products to increase income from the Lubuk Kertang community. Abstrak Desa Lubuk Kertang memiliki potensi ekowisata mangrove yang saat ini terus dikembangkan sebagai salah satu pemasukan sumber pendapatan ekonomi masyarakat selain nelayan dan pertanian. Bahkan ekosistem mangrove di Desa Lubuk Kertang menjadi ikon wisata Langkat. Selain ekowisata mangrove, Lubuk Kertang juga khas dengan produk olahan mangrovenya berupa makanan seperti dodol mangrove, kerupuk jeruju dan sirup dari buah mangrove. Namun produktivitasnya terkendala oleh ketersediaan buah mangrove yang tergantung dengan musim. Beranjak dari hal tersebut maka perlu dilakukan kegiatan pengabdian pada masyarakat untuk memberikan edukasi tentang potensi dan manfaat limbah tanaman mangrove baik berupa batang, ranting, daun dan buah dari aspek yang lain. Yaitu bahwa selain dapat diolah sebagai bahan pangan limbah tanaman mangrove juga dapat diolah menjadi produk bernilai tinggi lainnya, salah satunya sebagai pewarna alami. Kegiatan yang dilakukan adalah dalam bentuk sosialisasi dan edukasi tentang potensi dan manfaat limbah tanaman mangrove sebagai zat pewarna alami hingga proses pembuatannya. Selanjutnya pewarna alami yang telah dihasilkan diaplikasikan dalam proses pewarnaan melalui kegiatan workshop/pelatihan ecoprint. Media yang digunakan adalah kain/tekstil, kertas, kulit domba dan keramik (mug). Respon masyarakat yang diwakili oleh ibu-ibu kelompok tani wanita mandiri serta beberapa siswa Madrasah Tsanawiyah dan Kepala Desa sangat baik. Bahkan beberapa ibu-ibu dari kelompok tani wanita mandiri secara rutin terus membuat olahan ecoprint berupa kain, pashmina dan kaos. Hasil produksi mereka juga telah diikutserakan pada kegiatan pameran di Desa Lubuk Kertang. Kepala Desa Lubuk Kertang mengharapkan adanya keberlanjutan dari kelompok tani wanita mandiri untuk membuat produk-produk ecoprint dalam rangka menambah pemasukan dari masyarakat Lubuk Kertang.

Abstract

The effects of salinity on the polyisoprenoid alcohol content and composition of the salt-secreting mangrove species Avicennia marina and Sonneratia alba and the non–salt-secreting species Bruguiera gymnorrhiza and Kandelia obovata were studied. The seedlings of mangroves were grown for 5 months under 0% and 3% salt concentrations. The occurrence, content, and distribution of four mangrove seedlings were analyzed by two-dimensional thin layer chromatography. The structural groups of the polyprenols and dolichols in the leaves and roots were classified into two types (I and II). In type I, dolichols predominated over polyprenols (more than 90%), whereas in type II, the occurrence of both polyprenols and dolichols was observed. Polyprenols were not detected in the leaves of A. marina and B. gymnorrhiza under 0% salt (control), but were detected in small amounts in K. obovata leaves; however, significant amounts were found in the 3% salinity group. This finding in A. marina, B. gymnorrhiza, and K. obovata leaves implies a change to the structural group: under 0% salt concentrations, the groups are classified as type I, but become type II under 3% salt concentrations. The occurrence of ficaprenol (C50–55) was found only in the leaves of the non–salt-secreting species B. gymnorrhiza and K. obovataunder 3% salinity and not in the salt-secreting species A. marina or S. alba. It is noteworthy that the polyisoprenoid type in the roots of the four species showed no change under salinity; the two salt-secreting species A. marina and S. alba contained type I under 0% and 3% salt concentrations. On the other hand, type II polyisoprenoids were identified in the non–salt-secreting species B. gymnorrhiza and K. obovata under 0% and 3% salinity conditions. This finding suggested that polyisoprenoids play a protective role against salinity in the mangrove leaves of both salt-secreting and non–salt-secreting species.

Abstract

The present study describes the growth and biomass of salt secretor mangrove, Avicennia marina and the non-secretor Rhizophora stylosa by long-term exposure to salinity and its subsequent fresh water. The seedlings of the 2 mangroves grown with varying salt concentration for 3 months were then divided into 2 treatment groups, and grown for another 3 months: 1 continuously in salinity conditions and another in fresh water to recover from salinity. The growth parameter namely plant height and diameter of A. marina was significantly enhanced by salt with maximal stimulation at 2% (equal to 75% natural seawater) and this increase appeared to be attenuated by increasing the salinity concentration above 2%. By contrast, the growth of R. stylosa significantly thrived up to 0.5% salt concentration, then decreased with the increasing of salinity. The growth of both species slightly increased after removal to salinity. Our findings suggested that within the range of salinity treatments, A. marina was more salt tolerant than R. stylosa, which provides important information for mangrove rehabilitation in North Sumatra. The biomass of the 2 mangrove seedlings was changed in the same manner as the growth of plants upon salt and fresh water treatment. These results suggested the importance of mangrove adaptation withstand salt and/or water stress.

Abstract

Mangrove forest in the context of climate change is important sector to be included in the inventory of greenhouse gas (GHG) emissions. The present study describes land-use and land-cover change during 2006–2012 of a mangrove forest conservation area, Karang Gading and Langkat Timur Laut Wildlife Reserve (KGLTLWR) in North Sumatra, Indonesia and their implications to carbon dioxide emissions. A land-use change matrix showed that the decrease of mangrove forest due to increases of other land-use such as aquaculture (50.00%) and oil palm plantation (28.83%). Furthermore, the net cumulative of carbon emissions in KGLTLWR for 2006 was 3804.70 t CO2-eq year-1, whereas predicting future emissions in 2030 was 11,318.74 t CO2-eq year-1 or an increase of 33.61% for 12 years. Source of historical emissions mainly from changes of secondary mangrove forests into aquaculture and oil palm plantation were 3223.9 t CO2-eq year-1 (84.73%) and 959.00 t CO2-eq year-1 (25.21%), respectively, indicating that the KGLTLWR is still a GHG emitter. Mitigation scenario with no conversion in secondary mangrove forest reduced 16.21% and 25.8% carbon emissions in 2024 and 2030, respectively. This study suggested that aquaculture and oil palm plantation are drivers of deforestation as well as the largest of GHG emission source in this area.

Abstract

In order to alleviate the deleterious effects of salinity, different types of phytohormones have been used. Among them, GA3 has been the main focus of some plant scientists. This study aimed to evaluate the effect of gibberellic acid and salinity on growth and production of roselle (Hibiscus sabdariffa L). This research was conducted in a greenhouse of Agriculture Faculty, University of Sumatera Utara, Medan. The study used utterly randomized design with two factors. The first factor was gibberellic acids. They were gibberellic acid (5 mg L-1) and no gibberellic acid. The second factor was salinity. They were 0 dsm-1 and 4-5 dsm-1. The interaction between gibberellic acid and salinity acid indicated a significant effect on the percentage of germination, chlorophyll a and b and beta-carotene. The application of giberellic acid helped in the tolerance of plants to salinity. Thus, application of GA3 become essential to improve overall productivity in salinity.
