Abstract

Gewang merupakan tanaman serbaguna bagi masyarakat Timor. Berbagai bagian dari tanaman ini telah digunakan untuk bahan bangunan, peralatan rumah, makanan, dan pakan; namun berbagai aktivitas alih lahan menyebabkan populasinya secara umum berkurang. Penelitian ini dilakukan untuk mengkaji sebaran dan kondisi lingkungan tanaman gewang dengan lokasi tinjau Kabupaten Kupang pada dua Kecamatan. Pengambilan data lapangan pohon Gewang dilakukan dengan metode sensus sehingga populasi pohon Gewang terambil seluruhnya pada semua lokasi penelitian. Adapun pohon Gewang yang menjadi obyek studi didefinisikan berdasarkan diameter yaitu hanya Gewang dengan diameter > 10 cm yang diambil datanya. Berdasarkan tujuh desa sampel pada Kecamatan Kupang Timur dan Kecamatan Nekamese, Kabupaten Kupang tercatat 3.132 pohon gewang. Jumlah pohon Gewang terbanyak terdapat pada Desa Nunkurus dengan jumlah 792 pohon (25% dari total pohon Gewang) dan paling sedikit di Desa Taloetan dengan jumlah 276 pohon (9%). Sebagian besar pohon Gewang ditemukan pada formasi semak belukar (44%) dan areal pertanian (35%) dengan total akumulasi mencapai 79 %. Tutupan bervegetasi padat (termasuk hutan Gewang) pada Kecamatan Kupang Timur berkecenderungan (trend) semakin berkurang dari waktu ke waktu yaitu dari luasan 4.150 ha pada tahun 1988 menjadi 2.476 ha pada tahun 2017, yaitu dengan laju penurunan 410 ha per dasawarsa (10 tahun) atau sekitar 41 ha setiap tahunnya.

Abstract

Hutan mangrove merupakan ekosistem pantai yang penting dipertahankan karena fungsinya sebagai penyedia sumber daya alam. Kawasan Suaka Margasatwa adalah area yang ditetapkan untuk melindungi satwa liar dan habitatnya, serta mendukung konservasi keanekaragaman hayati. Hutan mangrove Danau Tuadale pada kawasan suaka margasatwa mengalami kerusakan akibat aktivitas masyarakat seperti penebangan untuk lahan tambak dan pemanfaatan kayu, serta dampak dari tumpahan minyak dari Sumur Minyak Montara di Laut Timor pada tahun 1998 yang menyebabkan kematian ribuan pohon mangrove, kerugian ekonomi, sosial, dan lingkungan. Penelitian ini bertujuan untuk mengetahui status kesehatan ekosistem hutan mangrove di Danau Tuadale menggunakan metode Forest Health Monitoring (FHM), yang menilai empat indikator utama: Vitalitas fokus pengamatan penilaian kerusakan pohon dan kondisi tajuk, Produktivitas: luas bidang dasar (LBDS) dan volume kayu, Biodiversitas: indeks kekayaan jenis, indeks keanekaragaman jenis dan indeks kemerataan jenis, Kualitas Tapak: pH tanah, salinitas air, dan kapasitas tukar kation (KTK). Pengambilan sampel tanah secara purposive sampling. Pengambilan sampel tanah diambil pada tiga zona yaitu pada zona proksimal, middle dan distal dengan menggunakan ring sampel. Hasil penelitian menunjukkan bahwa vitalitas pohon di Danau Tuadale berada pada kategori sedang, dengan banyaknya pohon yang mengalami kerusakan fisik. Indikator produktivitas menunjukkan kategori sedang berdasarkan perhitungan luas bidang dasar dan volume. Indeks biodiversitas menunjukkan kekayaan jenis yang rendah, keanekaragaman jenis yang juga rendah, dengan kondisi lingkungan yang kurang stabil dan kemerataan jenis tinggi. Penilaian kualitas tapak menunjukkan bahwa derajat keasaman tanah berkategori kebasaan sedang, salinitas air rendah, dan kapasitas tukar kation (KTK) sangat tinggi.

Abstract

Sandalwood (Santalum album Linn.) is a forest wood-producing plant in East Nusa Tenggara (ENT) province that has high economic value and is an endemic species. Efforts to restored sandalwood plants in ENT have been carried out, such as development efforts by planting sandalwood from nurseries, as well as maintaining saplings that comes from natural spreading, but these efforts has not been successful enough. Giving rice husk biochar and rice straw compost in planting media can increased the availability of phosphorus (P), nitrogen (N), potassium (K), sulfur (S), calcium (Ca) and magnesium (Mg).The method used in this study is Complete Randomized Design (RAL) with a comparison of the composition of the planting media used (M0) Soil 100% Control 10 Kg, (M1) Soil 50% + 50% Biochar Rice Husk, (M2) Soil 50% + 50% Rice Straw Compost, (M3) Soil 25% + 50% Rice Husk Biochar + 25% Rice Straw Compost, (M4) Soil 25% + 25% Rice Husk Biochar + 50% Rice Straw Compost, (M5) Soil 50% + 25% Rice Husk Biochar + 25% Rice Straw Compost.The results of this study showed that the germination percentage value was 38.67% in M4 treatment. M4 treatment with a ratio of soil planting media 25% + 25% Rice Husk Biochar + 50% Rice Straw Compost, provides the highest average increase and has a very significant effects on germination, germination rate index, and germination value.

Abstract

The mining concession in the Protected Forest Area that occurred in 1994 resulted in forest ecological damage. The damage occurs by dismantling trees and soil to take the manganese in them. This research was conducted in the Nnggalak Rego RTK 103 Protected Forest Area, Reok District, Manggarai Regency, East Nusa Tenggara Province with the aim of the research being to explain changes in land cover before and after mining in the Protected Forest Area. Data analysis used in this study is a quantitative analysis that utilizes remote sensing data using satellite imagery interpretation techniques. The method used in this research is OBIS (Object Based Image Segmentation) were analyzed to determine the area of ​​land cover in 1992, 2002, 2012 and 2022 as well as changes in land cover from 1992 to 2022 in mining concession areas. The results showed that there were changes in the area of ​​protected forest in 2002, 2012 and 2022. In 1992 the mining class was 0 Ha, the mining concession entered in 1994 the forest area changed, and in 2002 the mining class was 22.14 Ha or 3.87% , in 2012 61.69 Ha or 10.78%, in 2022, 15.45 Ha or 2.70%. The cessation of mining activities in 2013 to 2022 will result in a change in land cover class, namely the dense forest class will experience an increase in area due to succession and climate that occurs in the Manggarai district. Efforts to restore protected forests to their main function, it is suggested that reclamation and rehabilitation of post-mining land should be carried out.

Abstract

Sandalwood is a type of plant native to Indonesia that grows endemic to several islands in the East Nusa Tenggara region. This study aims to determine the effect of planting media on the growth of sandalwood seedlings. This study used a completely randomized design (CRD) analysis with Duncan Multiple Range Test . Observations were made on the growth of height, diameter, number of leaves, fresh weight and dry weight of the seedlings. The results showed that the treatment of the growing media had a very significant effect on the height of the seedlings, and had a significant effect on the stem diameter and number of leaves, while it had no effects on the wet and dry weight. The best treatment was obtained from the M3 treatment (soil mixed with chicken faeces), which was shown with an average seedling height of 12.56 cm, a seedling diameter of 1.88 mm and a total of 13.8 leaves.

Abstract

White teak, which has the scientific name Gmelina arborea, is a productive wood-producing tree. White Teak (Gmelina sp.) is a wood-producing tree which has a yellowish-white color with fine fibrous and gray skin. The use of this wood is for construction materials, furniture, pulp, floor raises, carpentry tools and so on. Mycorrhiza is a group of soil fungi whose life prefers to cooperate with plant or tree roots, so that these fungi get a supply of liquid sugar from plants and vice versa these fungi exchange it in the form of water and nutrients needed for plant growth. This study aims to determine the effect of optimal mycorrhizal doses on the growth of white teak seedlings. This study used a completely randomized design (CRD) analysis with Ducan's Ducan Multiple Reange Post Test. Observations were made on the increase in seedling height, increase in stem diameter and number of leaves. The results showed that the treatment of the growing media had no effect because the doses given were insufficient.

Abstract

Non-Timber Forest Products ( NTFPs) are one of the forest resources that have comparative advantages and are in direct contact with communities around the forest. NTFPs in East Nusa Tenggara Province, which has potential is honey derived from the forest honey bee Apis dorsata. This research was conducted by observation, and interviews. Forest Bees (Apis dorsata) in Nenas village always keep the same nest tree for nenas every year or period. In Nenas village there are 7 trees with 5 active nest trees and 2 inactive nest trees, which are the breeding place for Apis dorsata forest honey bees, with tree species such as Banyan (Ficus benjamin), Angkai (Albizzia chinensis), Bonak (Tetrameles nudiflora), Eucalyptus (Melaleuca leucadendra), and Cassowary (Casuarina). With a dense canopy cover of about 80% and with an average tree height of 29 m and a nest height of about 20 m, with a tree diameter of 70-150 cm, the number of clones / nest trees of 10-20. Forest beehive trees at the study site are at an altitude (elevation) of 1,285-2,500 mdpl, and a slope level of 60%, with a humid climate that rains 2000-3000 mm / year. With a climate of 140C-290C and at extreme conditions at a temperature of 90C. Conditions of temperature and rainfall greatly affect the quality of food from forest honey bees the harvesting process is still very traditional using climbing and smoke methods and traditional ceremonies which are carried out at night. Nenas Village is still included in a protected forest area managed by the Forestry Service and there is no permit for traditional honey bee to take the honey because the Apis dorsata forest honey bee tree is community property or private property which is a relic from ancient times. The age range of respondents is 30-70 years, with the highest education are high school and university graduated, and local people work as farmers and ranchers.
