Abstract

Mangrove forests are important life-supporting ecosistem in coastal areas. According to Macnae (1968), mangrove is defined as a group of vegetation that grow between the highest water level during high tide and the lowest water level during low tide. At Teluk Pambang village, an organization called Kelompok Pengelola Mangrove (KPM) Belukap was formed due to the anxiety of nearby people to further irresponsible demage of mangrove forests. After the co-fish project, a group was created to manage and project mangrove forests for fishery activities. This research aims to study the contribution of mangrove forest conservation to the income of KPM Belukap at Teluk Pambang village, Kecamatan Bantan, Kabupaten Bengkalis, Riau Province. Contribution of mangrove forest conservation and income data were collected, tabulated, analyzed. Income data were collected descriptively using survey papers. Analysis result show that the conservation of mangrove forests increase the income of KPM Belukap by 1,20% to 3,75%.   Keywords: Contributions, Mangrove Forest, Income, Conservation

Abstract

Nypa fruticans Wurmb producing sap that can be obtained through wiretapping fruit bunches. Nipa sap fresh taste sweet because it contains sugar which is quite high. Nipa sap is processed into bioethanol as a renewable energy source that is being developed still find obstacles in its management due to the community when the sap has been tapped then collected, indirectly sold and stored. The yield of bioethanol is one of the considerations in the process of bioethanol production from nipa sap. Nipa sap sugar levels are high it is possible to produce a high yield. This research aim to determine the effect of storage long time the sap nypa to the yield of bioethanol. This research was conducted experimentally by the method of completely randomized design (CRD) with 5 treatments and 3 replications. The treatments used were P1 = storage long for 24 hours, P2 = storage long sap for 36 hours, P3 = storage long for 48 hours, P4 = storage long sap for 60 hours, P5 = storage long sap for 72 hours. Data was analyzed by regression analysis. The results of this research shows that the nipa sap storage time significantly affect the yield of ethanol produced. The yield of the resulting fewer and fewer when the sap is stored longer. Keywords: Nypa fruticans Wurmb, Bioethanol, The Yield Of Bioethanol

Abstract

Ekosistem mangrove merupakan suatu komunitas tumbuhan yang khas, dipengaruhi pasang-surut air laut. Sungai Kembung merupakan salah satu ekosistem mangrove di Pulau Bengkalis dan saat ini cenderung mengalami tekanan seperti adanya aktivitas budidaya tambak udang dan penebangan liar. Penginderaan jauh dapat dijadikan sebagai solusi dalam pemantauan ekosistem mangrove. Penelitian ini bertujuan untuk memetakan penutup lahan mangrove Sungai Kembung menggunakan citra satelit Sentinel-2A dengan penerapan algoritma klasifikasi nearest neighbor. Segmentasi multiresolusi dengan nilai parameter scale yang berbeda (10, 30, 50, 100 dan 150) digunakan untuk menghasilkan objek penutup lahan. Hasil penelitian menunjukkan bahwa segmentasi terbaik diperoleh dari nilai scale 30 dengan jumlah objek sebanyak 10.750. Semakin besar nilai scale maka jumlah objek yang tersegmen semakin sedikit serta nilai akurasi keseluruhan yang dicapai cenderung menurun. Hasil perhitungan matrik kesalahan menunjukkan akurasi keseluruhan terbaik sebesar 74%. Penelitian ini merekomendasikan penerapan nearest neighbor sebagai algoritma klasifikasi alternatif untuk memetakan penutup lahan mangrove.

Abstract

Aquilaria malaccensis is one of the plants used for peatland restoration activities. Provision of quality A.malaccensis seeds is needed in conservation activities. To get a good quality of A.malaccensis must use proper cultivation techniques. Mycorrhizae and Trichoderma spp. can improve seedling growth and suppresses pathogenic. Application of mycorrhizae and Trichoderma spp. are on of the success techniques of cultivation, but need to know the potential time to apply. For this reason, this research was conducted to determine the potential time application of mycorrhizal and Trichoderma spp. to increase seddling growth. This research used a completely randomized design (CRD), which consist of 5 treatmens, 10 replications and each replication consisted of 1 seedling. The treatments used were : T1 = Trichoderma spp. on S-5 and mycorrhiza on S-1, T2 = Trichoderma spp. on S-3 and mycorrhiza on S-1, T3 = Trichoderma spp. and mycorrhiza on S-1 , T4 = Trichoderma spp. on S-1 and mycorrhiza on S-3, T5 = Trichoderma spp. on S-1 and mycorrhiza  on S-5, where S = seedlings were transferred to polybags after treatment. The parameters measured were seedling survival percent, seedling height increase, seedling diameter increase, plant dry weight, and root canopy ratio. The results of this research that the application of Trichoderma spp. in 5 days before the seedling were transferred to polybags and mycorrhizae 1 day before the seedlings were transferred to polybags showed the best result for the growth of A.malaccensis seedlings with seedling height increase is 5,13 cm, plant dry weight is 1,14 g and top-root ratio is 3,09. Keywords : Aquilaria malaccensis, mycorrhizae, Trichoderma spp., peat medium

Abstract

Bukit Tigapuluh National Park has an ODTW (Tourist Attraction) that is attractive for tourists to visit and has a unique tourist attraction, namely the Granit area, a former Granit mining area. One of the dominant plant species in the Granit area's tourist attraction in Bukit Tigapuluh National Park is Shorea spp. This study aims to determine the diversity of species and morphology of Shorea spp. in the Granit tourist area in Bukit Tigapuluh National Park, Riau Province. This study used a purposive sampling method using a pathway system. The composition of tree species uses manuals and tree species records to obtain observations of species diversity, while morphological observations can be taken using cameras or data from the Bukit Tigapuluh National Park as supporting material. The results showed that the morphology of each Shorea spp. Species seen from the shape of the leaves and stems had differences. The diversity of meranti species (Shorea spp.) In the Granit area of Bukit Tigapuluh National Park (TNBT) was eight species with 67 individuals. The index value of species diversity (H ') in Granit Bukit Tigapuluh National Park (TNBT) is line 1, which is 1.81 in the medium category, and lane two is 0.89 with the low category, and lane 3 is 0.82 with the low category. Keywords: Morphology, national park, shorea spp.
