Mangrove forest in North Central Timor Regency is dominated by Rhizophora sp. The highest number was found in Tuamese Village, namely Rhizophora apiculata and Rhizophora mucronata. The biomass productivity in mangrove forests varies according to age, dominant species, and locality. It shows differences in carbon uptake and storage at the level, type, and place of growth. This study aimed to analyze the carbon content and carbon uptake of R. apiculata and R. mucronata at the stake level to the tree level in two plots with the size of 2,000 m2 each. The method used was allometric equations, while the power discrimination test used an independent sample t-test. The result showed that R. apiculata and R. mucronata had the same potential in producing biomass and necromass as well as in storing and absorbing carbon. The total biomass was 77.21 Mg/ha, which can absorb and store carbon, respectively, 141.68 Mg/ha and 36.61 Mg/ha. This research data provides an overview of the potential of biomass in meeting carbon trading standards as an effort to succeed in mangrove conservation in Tuamese Village.

Penelitian ini bertujuan untuk mendeskripsikan komposisi dan keanekaragaman jenis pohon di Hutan Lindung Lapeom. Penelitian dilaksanakan pada bulan November sampai Desember 2009 menggunakan metode kuadrat dengan menempatkan plot disepanjang garis transek. Jumlah transek 5 buah, panjang transek 200 m, di setiap transek diletakkan 5 plot pengamatan dengan ukuran 20 m x 20 m. Hasil penelitian menunjukkan bahwa ditemukan 22 jenis pohon dari 17 famili. Famili dengan jumlah spesies terbanyak adalah famili Caesalpinaceae sebanyak 4 spesies yakni Casia fistula, L, Delonix regia, Rafin, Cassia simea, Lamk, dan Tamarindus indica, L. Jenis dengan jumlah individu terbanyak adalah Mangifera indica, L dari famili Anacardiaceae sebanyak 20 individu. Spesies dengan indeks nilai penting tertinggi adalah Mangifera indica (43,7%), sedangkan jenis yang memiliki indeks nilai penting terendah adalah Zizipus jujuba (1.8%,) dan Jatropa Sp (1.9%). Indeks Keanekaragaman jenis pohon di hutan lindung lapeom termasuk kategori sedang dengan nilai 2.7 hal ini menunjukkan bahwa wilayah hutan lindung lapeom merupakan wilayah yang memiliki tingkat produktivitas pohon yang cukup, kondisi ekosistem yang cukup seimbang dan memiliki tekanan ekologis yang sedang. Dari hasil penelitian dapat disimpulkan komposisi jenis hutan laepom sebanyak 22 jenis pohon dalam 17 famili, Jenis yang paling banyak jumlah individunya adalah Mangifera indica, L dari famili Anacardiaceae Spesies yang memiliki indeks nilai penting tertinggi adalah Mangifera indica (43, 7%) dan jenis yang memiliki indeks nilai penting terendah adalah Zizipus jujuba (1.8%), Indeks Keanekaragaman jenis pohon di hutan lindung lapeom termasuk kategori sedang.

The development in Wini Beach coastal area will have an impact on the destruction of the mangrove ecosystem which is a habitat for the life of the macrozoobenthic fauna. This study aims to determine the community structure of macrozoobenthos including abundance, diversity, evenness and dominance of the type of macrozoobenthos in the mangrove area. The study was carried out in the District of North Insana which included the mangrove area of Temkuna Beach (station I) and the mangrove area of Tanjung Bastian Beach (station II). Taking macrozoobenthos samples was carried out at low tide using the line transect method which was made perpendicular to the land in the mangrove forest area. The results of the study found 13 types of macrozoobenthos fauna spread over 2 stations namely the 8-type gastropod class, bivalvia class 4 types and 1 type crustacean class. Medium category (H ') = 2.41 index, Uniformity Index (E) = 0.938 classified as stable community and Dominance index (D) = 0.10 low category. The Equity Index score is classified as a stable condition where no macrozoobenthos species dominate.

Lontar (Borassus sundaicus,Beck) adalah jenis palma yang tumbuh di daerah kering. Di Indonesia, lontar banyak ditemukan di Nusa Tenggara Timur. Produk utama lontar adalah nira dari sadapan bunga, dapat diminum langsung atau diolah jadi gula. Nira yang dijadikan sumberdaya unggulan daerah ini perlu dikembangkan, sebab memberi nilai tambah terhadap pendapatan perkapita dan kesejahteraan.Pemanfaatan nira lontar sebagai gula merah cetak di Kabupaten Timor Tengah Utara (TTU) masih dominan dilakukan oleh warga etnis Sabu dan Rote. Sedangkan masyarakat lokal, suku Dawan dominan memanfaatkan nira lontar untuk minuman beralkohol (sopi). Di Kabupaten TTU, Kota Kefamenanu Kelurahan Maubeli terdapat pohon lontar yang belum dimanfaatkan. Terutama  yang memproduksi nira lontar menjadi gula merah cetak. Alat, bahan seadanya dengan proses pembuatan tanpa melalui tahapan penyaringan secara baik. Sehingga penampilan gula merahnya kurang menarik. Dampaknya harga pasaran gula di bawah harga pasaran gula merah dari daerah lain yang sudah olah secara higienis.Tujuan kegiatan pengabdian ini adalah pemanfaatan nira lontar sebagai gula merah cetak melalui pelatihan dan pendampingan serta perbaikan tahapan pengolahan secara higienis, dengan perlakuan media kemasan yang menarik untuk peningkatan harga dan pendapatan petani. Hasil gula merah cetak petani mulai diterima dipasaran toko maupun mini market di kota Kefamenanu. Dampak yang dirasakan petani yakni pendapatan meningkat.

Nowdays, the necesity of the water go up on every sectors, so that it caused the water go down because of the management is not good enough. The purpose of this study is to know the kinds of the vegetation that found in the haze, that can be benefit to suport the water availibility and conservation, to know the potency of the vegetacy as the water availibility and conservation an also to know the society role to support it. This study is started from December 2020 until March 2021 placed in haze Banfanu village, North Central Timor regency. This study is used the qualitative and quantitave method. To collect the data and analysing the writer used an interview, observation and documentation. The determination estimasy data analysing is used point center quarter method (PCQM) to count point index value (PIV), the variety index shanon winner and averrage index. This study is made on twelve simpling with the vegetation data that is pick out from the tree, pilar and seedling. The result of this study is indicated that there are 28 species in the haze at the Banfanu village that consist of 16 families from 404 individu is devided in seedling, pilar and tree. The vegetation that could be benefit the water availibility and concervation is Switenia mahagoni, Casuarina junghuniana, Syzygum aqueum, Bambusa vulgaris, Ficus benjamina, Pandanus dubius Spreng, Paraserianthes falcataria (L) Nielsen, Anacardium occidentae L, Psidium Guajava L, Timonius sericeus (Deft) K. Schum, Syzygium cimunu L. The vegetation that indicate to keep up the water avalibility concervation is Bambusa vulgaris, the vicus kind is switenia mahogani, and iti is supported by the data analysis is higher index point value to tree strata is tectona grandis with IPV 74.50% and the lower IPV is Musa paradisiaca with IPV 1.80%. The higher point value for the pilar is Gliricidia sepium with IPV 92.13% and the lower is Vachellia leucophloea with IPV 2.99%, the high IPV for seedling is Tectona grandis with IPV 46.80% and the lower is switenia mahogani L and Sesbiana grandiflora with IPV 0.90%. The variety index value Shanon Winner and the averrage index categorize is lower. The vegetacy kind in the haze of Banfanu village categorize lower variety vegetacy, bad productivities, the condition is not rateable and lower pressure, but the ratebale index happend because of the domination on the kind certain species and in generally the kind of plant that growth up is limited. In other hand, the knowledge of the society is not enough to keep the water availibility and concervation and also the vegetacy is a polemic to the society.
