Abstract

ABSTRAKFakta perubahan iklim yang terjadi saat ini mendesak seluruh pihak untuk ikut berkontribusi dalam melakukan mitigasi dan adaptasi, agar dapat mengurangi dampak atau resiko yang ditimbulkan.  Ruang lingkup program Indonesia’s FoLU Net Sink 2030 salah satunya relevan dengan konsep blue carbon yang saat ini juga menjadi fokus pemerintah khususnya sektor perikanan dan kelautan dalam usaha menyerap emisi karbon. Tujuan penelitian ini adalah menganalisis potensi serapan karbon ekosistem mangrove Pilohulata sebagai salah satu gugus mangrove yang terdapat diwilayah pesisisr pantai dan laut Kecamatan Monano.  Hasil penelitian menunjukkan bahwa potensi keanekaragaman spesies vegetasi mangrove pilohulata termasuk dalam kategori sedang.  Nilai kemerataan jenis yang dimiliki masuk dalam kategori sedang walaupun cenderung rendah, sedangkan nilai kekayaan jenis vegetasi mangrove pilohulata termasuk dalam kategori rendah.  Kondisi ini tentu saja berdampak pada jumlah serapan karbon yang dimiliki oleh vegetasi mangrove yang ada di Pilohulata.  Nilai serapan karbon tertinggi terdapat pada vegetasi mangrove struktur tingkat pohon sebesar 2081,23 ton/ha sedangkan nilai terendah terletak pada struktur tingkat semai sebesar 52,74 ton/ha.  Nilai serapan CO2 vegetasi mangrove pilohulata tertinggi terdapat pada struktur tingkat pohon sebesar 7638,10 ton/ha, sedangkan nilai terendah terdapat pada struktur tingkat semai sebesar 193,55 ton/ha.  Diketahui bahwa nilai serapan karbon vegetasi mangrove berbanding lurus dengan kemampuan vegetasi mangrove menyerap CO2 di udara, bahkan mangrove dapat menyerap CO2 lebih banyak 27% dari jumlah karbon yang diserap dan disimpan dalam tanaman.ABSTRACTThe fact that climate change is currently occurring urges all parties to contribute to mitigation and adaptation, in order to reduce the impacts or risks caused. One of the scopes of Indonesia's FoLU Net Sink 2030 program is that it is relevant to the blue carbon concept, which is currently also the focus of the government, especially the fisheries and marine sectors, in an effort to absorb carbon emissions. The aim of this research is to analyze the carbon uptake potential of the Pilohulata mangrove ecosystem as one of the mangrove clusters found in the coastal and marine areas of Monano District. The results showed that the diversity potential of pilohulata mangrove vegetation species was included in the moderate category. The species evenness value is in the medium category although it tends to be low, while the species richness value of the pilohulata mangrove vegetation is included in the low category. This condition certainly has an impact on the amount of carbon absorption owned by the mangrove vegetation in Pilohulata  The highest carbon uptake value is found in the tree-level structure of mangrove vegetation at 2081.23 ton/ha, while the lowest value is at the seedling-level structure at 52.74 ton/ha. The highest CO2 uptake value for pilohulata mangrove vegetation was at the tree level structure at 7638.10 ton/ha, while the lowest value was at the seedling level structure at 193.55 ton/ha. It is known that the carbon absorption value of mangrove vegetation is directly proportional to the ability of mangrove vegetation to absorb CO2 in the air, in fact mangroves can absorb 27% more CO2 than the amount of carbon absorbed and stored in plants.

Abstract

ABSTRACTIndonesian National Standard (SNI) No. 8420 of 2018 concerning forest plant seeds is a reference for determining the quality of quality seeds. Technical instructions for assessing the quality of forest plant seeds by Regulation of the Director General of Land Rehabilitation and Social Forestry (RLPS) number P.05/V-SET/2009. Gmelina arborea and Aleurites moluccana seeds are priority seeds for production and use in RHL activities, so research focuses on these two types. The study aimed to determine the quality of Gmelina arborea and Aleurites moluccana seeds produced by the BPDAS-HL Bone Bolango Permanent Nursery. Data collection was carried out by selecting the sample using the Systematic Sampling with Random Start method based on SNI sampling requirements. There were 19,800 Gmelina arborea seeds and 5,900 Aleurites moluccana seeds with a sampling intensity of 0.2%. Testing for Gmelina arborea showed poor results in contrast to Aleurites moluccana in terms of percentage: Media compactness of the two types tested produced a percentage of 100% of the Aleurites moluccana type and 73.5% of the Gmelina arborea type. Seedling height, from the test percentages for both types, produces a percentage of 100%. For seed diameter, the Gmelina arborea test produced a value of 91%, and the Aleurites moluccana type produced a value of 100%. The percentage of leaves for the Gmelina arborea type is 45%, while the percentage for the Aleurites moluccana type is 100%. Average special requirements (RPK), the Gmelina arborea type produces a percentage of 77.37% while the Aleurites moluccana type produces a percentage of 100%. The test results (final score) resulted in 68 Gmelina arborea seedlings that fell into the first criterion (P), 120 in the second criterion (D) and 12 that did not pass the test (X). Meanwhile, the Aleurites moluccana type produces a percentage of 100% which is in the first quality (P).Keywords: Quality Testing; Seedlings; SNI; BPDASHL; Bone-Bolango.
VEGETATION AND TEMPERATURE AS DETERMINANTS IN THE EGG-LAYING BEHAVIOR OF HAWKSBILL TURTLES (ERETMOCHELYS IMBRICATA) AND LOGGERHEAD TURTLES (CARETTA CARETTA) Puspaningrum, Dian; Bachtiar, Bachtiar; Ernikawati, Ernikawati

Abstract

Vegetation and temperature are biophysical parameters that affect sea turtle nesting behavior. Coastal vegetation is essential to the nesting behavior of Loggerhead sea turtles. In contrast to Hawksbill sea turtles, Loggerhead sea turtles preferentially select sandy beaches for nesting. The study aimed to measure the impact of vegetation and temperature on sea turtle nesting behaviors and to offer detailed insights on adaptation and enhanced conservation techniques to save sea turtles from environmental changes. The study was performed on Popaya Island, within the Nature Reserve of Mas Popaya Raja Island, North Gorontalo, from January to March 2023. Identification of population and sample using the purposive sampling method for all turtles observed throughout the observation phase. The findings indicated that Hawksbill turtles (Eretmochelys imbricata) favored nesting in locations characterized by greater plant diversity and density, averaging 195 eggs per nest. Loggerhead turtles (Caretta caretta) deposited a comparatively lower number of eggs (88 eggs) than at other locations (96 - 108 eggs). Some eggs were found in places with no surrounding vegetation. The nesting activity of loggerheads in non-vegetated regions may have been affected by the shallowness of the holes and their comparatively broader width. The sand surface temperature in areas with dense flora and biodiversity decreases, impacting egg-laying activity as one moves further from the vegetation's border.
