Abstract

Peningkatan gas-gas efek rumah kaca sebagai hasil berbagai aktivitas manusia dapat menyebabkan terjadinya pemanasan global. Salah satu dampak dari pemanasan global yaitu perubahan iklim. Salah satu upaya yang dapat dilakukan untuk mengurangi dampak tersebut adalah meningkatkan peran mangrove sebagai penyerap karbon. Penelitian ini bertujuan untuk menentukan kandungan stok karbon pada tegakan mangrove dan C-organik pada sedimen mangrove. Metode sampling yang digunakan dalam penelitian ini adalah metode purposive sampling untuk menentukan enam stasiun penelitian, sampel diambil sekali tanpa pengulangan. Analisis C-organik menggunakan metode Spektrofotometri. Hasil penelitian menunjukan mangrove di Dukuh Tapak memiliki kandungan biomassa sebesar sebesar 1507,91 ton/ha, stok karbon sebesar 708,2 ton C/ha, dan mampu menyerap CO2 sebesar 2598,65 ton/ha. Pola hubungan antara kerapatan dengan biomassa, biomassa dengan stok karbon, dan stok karbon dengan serapan CO2 menunjukkan adanya tiga macam persamaan yang memiliki nilai korelasi (R) yang positif yaitu sebesar 0,67, 1,00, dan 1,00. Jenis sedimen pada penelitian ini yaitu lumpur berpasir dengan rata-rata C-organik sedimen mangrove sebesar 4,4 %. Simpulan dari penelitian ini adalah kandungan stok karbon mangrove di Dukuh Tapak lebih tinggi dari penelitian stok karbon di pulau Kemujan TN. Karimunjawa dan kandungan C-organik sedimen mangrove di Dukuh Tapak termasuk dalam kriteria tinggi. The enhancement of gases greenhouse effects as a result of human activities contribute to global warming. One of the effects of global warming is the climate change. One of the efforts which should be made to reduce these impacts is improve the role of mangroves as carbon sinks. The purpose of this study is to determine the content of carbon stock in mangrove stands and C-organic in mangrove sediments. The sampling method used in this research was purposive sampling method, in order to determine the six research stations, samples were taken once without repetition. C-organic analysis using spectrophotometry method. The results showed that mangrove in Tapak hamlet has a biomass content of at 1507.91 tons/ha, the carbon stock of 708.2 tons C/ha and capable of absorbing CO2 of 2598.65 tons/ha. The pattern of the relationship between the density of the biomass, the biomass carbon stock and carbon stock with CO2 uptake showed three kinds of equations that has a value of correlation (R) were positive in the amount of 0.67, 1.00, and 1.00, respectively. The sediment type in this study is sandy mud with an average C-organic mangrove sediments of 4.4 %. The conclusion of this research is the content of carbon stocks in Tapak hamlet mangrove is igher than the carbon stock research on the Kemujan island TN. Karimunjawa and the content of C-organic mangrove sediments in Tapak hamlet is in the high criteria.

Abstract

Palmyra (Borassus flabellifer L.) is the identity plant of Tuban Regency. The main palmyra product in Tuban Regency is the sap. In the last 5 years (2015-2020) the productivity of sap has not increased. This study aimed to determine the correlation between cultivation factors and palmyra production in the Semanding Subdistrict, Tuban Regency, Indonesia. The research was correlative research with quantitative descriptive explanatory. The independent variables were several tree ownership, nurseries, fertilization, tapping methods, and control of plant pests. The dependent variable was the productivity of the palmyra sap. The research data sources were the people in the villages of Kowang, Gedongombo, Tegalagung, and Prunggahan, with a total sample taken of 103 people. Data collection was carried out using observation and semi-structured interviews. The results were then analyzed using the multiple linear regression application SPSS 25. The results showed that all the factors in the model, through the F test, had a significant effect simultaneously. Partially using the t-test, the factors that influence the productivity of the palmyra sap are pest control, the number of trees, and tapping methods. Therefore, the result confirmed the correlation between cultivation factors and palmyra production in the Semanding Subdistrict, Tuban Regency, Indonesia.

Abstract

Sayung District is one of the district in Demak Regency which has mangrove vegetation. The alteration of Demak Regency's coastal areas caused by the sea rob phenomenon has a significant impact on the mangrove vegetation. The Semarang-Demak toll road construction along Sayung coast potentially causes mangrove damage. The purpose of this study is to determine the structure and profile, and analyze the condition of mangrove vegetation in Sayung, based on the structure and profile of Sayung mangrove vegetation. The study was conducted on the mangroves of Bedono, Mondoliko, and Morosari Village. This research used an exploratory method with descriptive analysis, by collecting data on vegetation parameters and vegetation profiles. The results showed that the types of mangroves found at all observation stations consisted of Avicennia, Bruguiera, and Rhizophora. The profile graph shows an association between Avicennia alba, Avicennia marina, and Rhizophora mucronata. Important Value Index (IVI) for all stations shows that Avicennia officinalis have highest value on 65,30 and 50,18 respectively. Diversity index shows that both stations have value on 0,873 and 0,893 which belongs to low diversity. Similarity index on each sub-stations shows the significant difference between Bedono-A, Bedono-C, Mondoliko, and Morosari stations at 0,4 index, Based on Abiotic parameters such as pH, salinity, and water temperature found on the optimal quality standard level. The conclusion is mangrove vegetation structure dominated by Avicennia and Rhizophora groups, with a low level of diversity at all observation stations.

Abstract

Penelitian ini dilakukan di Gunung Ungaran untuk mendukung program konservasi dan kelestarian daerah tersebut yang mengalami peningkatan lahan kritis akibat alih fungsi lahan oleh petani kopi. Penelitian dilakukan dari Mei hingga Oktober 2023 dengan metode survei vegetasi. Penelitian ini bertujuan untuk mengetahui pohon potensial untuk ditanam di lahan kritis berdasarkan kecepatan pertumbuhanya. Hasil penelitian menunjukkan bahwa jenis-jenis pohon yang paling potensial untuk ditanam di lahan kritis berdasarkan kecepatan pertumbuhan tinggi adalah Engelhardia serrata, Homalanthus populneus, dan Bischofia javanica. Berdasarkan kecepatan pertumbuhan diameter batang, bibit yang potensial adalah Peleman, Castanopsis argentea, dan Wuru Kopi. Selain itu, berdasarkan analisis vegetasi, jenis-jenis pohon paling potensial untuk restorasi lahan berdasarkan nilai Indeks Nilai Penting (INP) adalah Litsea sp. dan Ndog-ndogan pada strata 1, Parastemon urophyllus pada strata 2, dan Castanopsis argantea pada stratifikasi 3. Jenis-jenis pohon ini direkomendasikan untuk ditanam di lahan kritis Gunung Ungaran karena memiliki tingkat pertumbuhan dan kesuksesan yang tinggi. Upaya ini penting untuk memitigasi ancaman terhadap keanekaragaman hayati dan sumber air di Gunung Ungaran serta untuk mendukung masyarakat yang bergantung pada gunung ini.
