The research purposes: (1) Producing enriched compost of oil palm Empty Fruit Bunches (EFB) with coastal mud and rice husk biochar that is suitable for application to acid sulphate soils, (2) Getting the best dosage to increase acid sulphate soil fertility. The method used: complete random design (CRD) factorial pattern, the first factor composition of enriched oil palm EFB compost, second factor: doses of compost enriched. Data analysis using analysis of Varian (ANOVA), significant differences continued with Honestly Signiant Difference Test (HSD). The variables observed were: soil pH H2O, Each-Al, Total-N, Bray-P and each-K. The results showed: compost oil palm EFB treatment significantly affected the each-K, whilst did not significantly affect the pH H2O, Total-N, Bray-P and each-Al. Although enriched compost treatment did not significantly, and the finding is the treatment enriched compost trend to increased pH H2O, Total-N and Bray-P.

Sandalwood (cendana, Santalum album Linn.) is an endemic species of East Nusa Tenggara Province, which not only has economic value, but also as a symbol that the united of people or community and culture wisdom in East Nusa Tenggara Province. Sandalwood management had been strated many years ago; it has experienced ups and downs due to various factors, such as unsupported regional regulation on the efforts of developing sandalwood plantation. This research aimed to study sandalwood habitat and its population distribution in private land. Data were analysed with descriptive quantitative analysis. Sampling plots were placed purposively to determine important value index (IVI) and competition index (CI). Data were collected through interview with the stakeholders, direct survey, and desk study of secondary data. The result showed that sapling and seedling stages dominated the structure of sandalwood plantation in Timor Tengah Selatan (TTS), Timor Tengah Utara (TTU), and Belu Regencies. Then followed by poles and trees. IVI was high on every growth level of sandalwood in the three regencies, but CI was low with 0.18 for TTS, 0.07 for TTU, and 0.10 for Belu Regency.

GENETIC PARAMETER ESTIMATES FOR GROWTH TRAITS IN AN EUCALYPTUS UROPHYLLA S.T. BLAKE PROGENY TEST IN TIMOR ISLAND.Genetic parameters were estimated for growth traits of Ampupu (Eucalyptus urophylla S.T. Blake) progeny test grown in Southern Central Timor -East Nusa Tenggara Province, Timor Island. When the trial was one year old data were collected from 45 half-sib open pollinated families and assessed. There were genetic variations in height and diameter among families of E. urophylla. Growth traits had moderate heritability, both individually and in family, i.e. 0.28 and 0.55 for height and 0.41 and 0.66 for diameter, respectively. Genetic correlation between height and diameter was strong (0.96). However, the estimation of genetic parameter should be interpreted carefully since the trial was very young. Re-assessment of the trial should be carried out periodically to provide better understanding of the species regarding the dynamic of the genetic interaction between the species and its environment, effective age of selection and prediction of genetic gain.

One of the alternatives to mitigate  the limitations of agricultural land in urban areas in an effort to produce family food is the use of yard with verticulture method. However, the partners of this community service activity were housewives in Permata Griya RT Residence 03/RW 019; most of them have not utilized their home yard for any productive and economically valuable activities through plant cultivation. This is caused by the limited land and partners’ knowledge about plant cultivation techniques. This community service activity aims to provide training and practice of narrow land utilization with verticulture method, arranging plants vertically using used tins and plastic bottles.. The service activity was conducted through lecture, discussion, and demonstration approach. The result of the activity impacted on the participants’ knowledge and insight: all participants knew cultivation techniques and make the growing media of verticulture mainly by using used goods

Kelor is a plant species that has many benefits because of its nutritional content. The World Health Organization (WHO) has declared Moringa as a miracle plant, because it has saved many lives, especially children in many poor countries. Kelor has the opportunity to be developed in Sumatra, especially Riau as an alternative food crop, source of some important nutrients such as vitamins, proteins and anti-oxidants. Kelor from East Nusa Tenggara (NTT) is known to have the best quality in Indonesia. Its development in Riau requires preliminary research related to the growth of seedlings in several growing medium that have characteristics similar to those in Riau. This study uses a completely randomized design with treatment of growing medium in the form of three treatments, namely black soil, podsolic soil and peat soil mixture. The analysis was carried out descriptively and inference to the parameters of the percentage of life and height of Moringa seedlings. The results showed that seedling growing medium from top soil + fuel husk were best for Moringa seedling growth. Seedling growing media from top soil  sub soil or from top soil alone can be the best alternative afterwards.

ABSTRAKHutan rakyat berpotensi menjadi solusi defisit kebutuhan kayu secara lokal maupun nasional. Optimalisasi peran hutan rakyat memerlukan perencanaan yang tepat dan data yang akurat. Penelitian ini bertujuan untuk menentukan potensi dan komposisi kayu penyusun hutan rakyat di Malimada, Kecamatan Wewewa Utara Kabupaten Sumba Barat Daya, Nusa Tenggara Timur. Penelitian menggunakan pendekatan diskriptif kuantitatif dengan metode sampling kuadrat. Sampel berjumlah 10 plot yang diambil secara puposive. Indeks Nilai Peneting (INP) digunakan untuk menggambarkan potency kayu dan komposisi jenis penyusun hutan rakyat. Hasil penelitian menunjukkan bahwa mahoni (Swietenia macrophylla King) mendominasi tegakan dengan nilai INP pada tingkat sapihan, tiang dan pohon berturut-turut adalah 188,28; 211,28 dan 246,04. Struktur tegakan yang ada memiliki karakteristik yang hampir sama dengan hutan alam, hal ini terlihat dari grafik distribusi tingkat pertumbuhan yang berbentuk (J) terbalik (reverse J-shape).Kata kunci : potensi kayu, hutan rakyat, mahoni, analisis vegetasi ABSTRACT Private forests potentially solve the problem of local and national wood deficit. Optimizing the role of private forests, needs proper plannings and accurate data. This study aimed at determining wood potency and composition on private forest of Malimada, North Wewewa sub district, Southwest Sumba District of East Nusa Tenggara. This research used quantitative descriptive approach. Samplings purposive used quadrat methods with 10 plots were established. Important Value Index (IVI) was employed in order to depict wood potency and trees composition of private forest. The research results revealed that standing stock predominantly by mahogany (Swietenia macrophylla King.) with IVI at saplings, poles, and trees level were 188.28; 211.28 and 246.04 respectively. The existing structure stock has similar characteristics to the nature forest, this was indicated by reverse J-shape level of growth distribution curve.
