Abstract

The study used a Randomized Design Group (RAL) with 2 factors, the first factor being an organic ZPT(Z) with The standards are: Z0 (control), Z1 (150mg/l). ), Z2 (200mg/l), Z3 (250mg/l). ). Immersion time (P) with 3 levels namely P1 (2 hours), P2 (3 hours), P3 (4clock). There are 12 combinations of treatments that are repeated 3 times resulting in 36 experimental units. Experimental data is analyzed using variance analysis (ANOVA) and continued with real different tests (BNJ). The parameters observed in this study were: number of buds, height of buds, number of leaves, number of roots and length of roots. The results showed that the concentration of ZPT had a big effect on all parameters, because the length of immersion had a real effect on the parameters of the number of shoots and the length of the shoots, while on the parameters of the number of shoots and the length of the shoots. Shoots have a real effect, the leaves, the number of roots and the length of the roots have no real effect on all ages.Keywords: ZPT, Old Immersion, Lemon Cuttings Growth.

Abstract

Mangrove litters like leaves, branches and fruit will partly sunk under its own weight and blown by the currents of the ocean when sink back again to normal. Litter is carried away a current of who will be the organic matter and capable of being increases the production of litter yielded become an important factor in the transfer of hara of its vegetation those mangrove trees into the ground. This study aims to in order to understand the the production of mangrove litter in the area of those mangrove trees in Aceh Jaya. This research is right beside the road explorative and descriptive. The determination of the study locations is based on a method of purposive the sampling method of that has been assumed represent the regions of this research. The research results show the production of litter hutan mangrove in the remote and sparsely populated Rigaih of environmental friendly of the district of Aceh Jaya as much as 9.85 tons on higher demand for/ than one hectare in size/years. The type of whichdominant who gives hara of the largest memorials in hutan mangrove this is Rhizophora stylosa with the volume of production as much as litter 5.27 tons on higher demand for/than one hectare in size/years or about 53%. The parameter of the physical environment of to exert an influence upon the production of litter hutan mangrove in the area of environmentallyfriendly Aceh Jaya district. Keywords : environmentally friendly area, mangrove ecosystem, production litter

Abstract

Mangroves act as a filter to reduce the adverse effects of major environmental changes, and as a food source for marine life (Beach) and terrestrial biota. The Tsunami disaster of 2004 have resulted in changes in landforms such as mangrove forests. The damage of mangrove forests and then aggravated it again with pressure and increase the number of   resulted in any change land use and natural resource utilization. Mangrove management, should involve all components of the stakeholders which includes the role of Government, local institutions and communities. The purpose of this research was to assess the management of mangroves in the coastal area conservation efforts are integrated through the role of local governments in terms of planning, utilization, control, maintenance, surveillance, and law enforcement in Aceh Jaya Regency. This research includes the types of descriptive research with qualitative approach by describing the strategic role of pemerintahdaerah in the management of mangrove in the Aceh Jaya Regency. Based on the results of the study can be obtained that a summary of the factors facing the Government in the management of mangrove areas include factors financing became a major factor in the realization of program management of mangrove areas, the occurrence of farmed land expansion (neuheun), expansion of the area of the settlements, the lack of human resources so as to affect the economic conditions of the community. System management of mangrove area should preferably be done through a bottom up approach and done in sitematis starts from perencenaan stage, utilization, control, maintenance, supervision and law enforcement. Key words: the role of Government, revitalizing, mangrove management

Abstract

Hutan mangrove memiliki peran penting dalam menjaga ekosistem pesisir, tetapi mengalami degradasi akibat alih fungsi lahan dan aktivitas manusia. Penelitian ini bertujuan untuk menganalisis perubahan tutupan lahan dan karakteristik tanah mangrove di Kecamatan Setia Bakti, Aceh Jaya, menggunakan citra Sentinel-2 dalam Google Earth Engine (GEE). Analisis dilakukan dengan pendekatan indeks vegetasi Normalized Difference Vegetation Index (NDVI) serta menentukan tekstur tanah. Hasil penelitian menunjukkan bahwa tanah mangrove didominasi oleh tekstur lempung berliat dan lempung pasiran, yang memengaruhi pertumbuhan vegetasi. Analisis tutupan lahan mengungkapkan adanya peningkatan luas mangrove dari 147,98 hektare (2019) menjadi 176,67 hektare (2024). Peningkatan ini dipengaruhi oleh proses pemulihan alami dan upaya konservasi, meskipun beberapa area masih mengalami degradasi. Studi ini diharapkan dapat menjadi dasar dalam upaya pengelolaan mangrove secara berkelanjutan di wilayah pesisir Aceh Jaya.
