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

ABSTRAK Sub DAS Marisa merupakan salah satu sub DAS yang mengalami kerusakan. Adanya perubahan penggunaan lahan menjadi lahan pertanian mengakibatkan peningkatan terjadinya erosi. Tujuan penelitian adalah untuk menduga potensi erosi dengan aplikasi model Builder pada Sistem Informasi Geografis. Pengukuran potensi erosi menggunakan metode USLE (Universal Soil Loss Equation). Berdasarkan hasil analisis USLE bahwa Sub DAS Marisa nilai erosi tertinggi berada di Kecamatan Limboto Barat dengan luas 7.539,30 Ha. Faktor erosi yang paling berpengaruh di Sub DAS Marisa yaitu faktor CP dan LS. Mayoritas masyarakat merupakan petani sehingga banyaknya lahan pertanian di daerah tersebut. Faktor LS yaitu rata-rata keadan topografi di Sub DAS Marisa yaitu curam dengan kelas kemiringan lereng IV (25%-40%). Di Sub DAS Marisa kurangnya tindakan konservasi yang dilakukan masyarakat, sehingga banyaknya partikel tanah yang terdegradasi terbawa aliran oleh air hujan. Adapun tindakan konservasi yang dapat diterapkan antara lain pemberian mulsa dan penanaman dengan pola sistem agroforestry.  Kata kunci: Erosi; USLE; Aplikasi Builder. ABSTRACT  Marisa sub-watershed is one of the damaged sub-watersheds. The change in land use to agricultural land resulted in an increase in erosion. The purpose of this research is to estimate the erosion potential with the application of the Builder model in Geographic Information Systems. Measurement of erosion potential using the USLE (Universal Soil Loss Equation) method. Based on the results of USLE analysis that the Marisa Sub-watershed has the highest erosion value in the West Limboto District with an area of 7,539.30 Ha. The most influential erosion factors in the Marisa sub-watershed are CP and LS factors. The majority of people are farmers so there is a lot of agricultural land in the area. The LS factor is the average topography in the Marisa sub-watershed, which is steep with slope class IV (25%-40%). In the Marisa Sub-watershed, there is a lack of conservation action taken by the community, so that many degraded soil particles are carried away by rainwater. The conservation actions that can be applied include providing mulch and planting with an agroforestry system pattern. Keywords: Erosion; USLE; Builder Application

Abstract

The presence of a coal mining business permit not only has an economic impact but can also cause environmental problems. The objectives of this research are (1) to analyze the impact of PT XXX's overflowing voids on water management and water quality, and (2) to carry out spatial analysis, mapping and estimation of coal reserves that cannot be extracted by PT YYY. The research method is a case study selected by purposive sampling at two companies in North Kalimantan Province using water quality test analysis with grab sampling and estimating the potential loss of coal reserves using the rule of gradual changes and rule of nearest point methods as well as aerial photography. The research results show that in general the water use meets Class 3, namely: Water that can be used for cultivating freshwater fish, animal husbandry, water for irrigating crops, and/or other uses that require the same water quality as that use. Apart from that, PT XXX has built an overflow water channel into the PT YYY area without management approval, thus having a negative impact on PT YYY's mining plans which are dominated by peat land. Map of PT YYY's lost coal potential of 714,688 MT with an affected area of 15.16 hectares with details of 6.4 ha being the void area included in PT YYY's IUP area, 1.86 ha being the road and buffer zone area and 6.9 ha is a potential lost area of PT YYY.

Abstract

Propolis is a resinous material that bees gather from specific plant exudate streams and utilize to build hives, caulk or seal crevices, create funnels for bees to enter, store honey and pollen, maintain a warm environment, and function as a natural antibacterial. One type of propolis from the Meliponini Tribe, Propolis Homotrigona Apicalis, is made from resin of the damar tree. This research aims to present scientific data on the effects of propolis as an antibacterial in the human gastrointestinal system. The parameters examined included qualitative phytochemical activity, Porphyromonas sp, Steptococcus sp, and Eschericia sp activity as measured by the minimum inhibitory concentration (MIC) using the agar well method on Mueller Hiton Agar (MHA) media, as well as testing for antibacterial potency and comparing its activity to that of a positive chloramphenicol control. Using the cold maceration technique, 96% EtOH solvent was used to extract propolis over the course of three 24-hour periods. Alkaloids, flavonoids, triterpenoids, and carbohydrates were all active, according to the findings of phytochemical tests. According to the findings of the activity test, Porphyromonas sp, Steptococcus sp, and Eschericia sp all exhibited antibacterial activity. Propolis Homotrigona Apicalis has the potential to be utilized as a treatment that treats diarhea, gum inflammation, and bad breath since it has antibacterial action in these areas as well as a healthy digestive system.

Abstract

This research aims to determine community perceptions in forest management based on forest characteristics and forest management models in the Liawan Sub-watershed, Mamasa Watershed. Management and utilization of Indonesia's forest potential must be accompanied by maintaining and restoring previously existing ecosystem functions in order to maintain the preservation of forest ecosystems. Nevertheless. Local communities also act as conservator agents apart from only utilizing the potential of forest resources as well as a component of its management. Until the early 1970s, the local wisdom of very diverse communities still dominated forest management systems throughout Indonesia, especially outside Java. Indigenous communities, which have not had much intervention from exploitative government policies, still manage their customary forests autonomously to ensure the continuity of community life. The local knowledge of the people who live in the Liawan Sub-watershed is very important to know that the people still maintain the proper order of water sources. People living in the Liawan Sub-watershed area are very dependent on forests which contain water sources from Mount Sareong for clean water, agriculture and electricity generation purposes. There are many applications of local community knowledge in forest management around the Liawan watershed that need to be published as teaching materials and additional knowledge.
