Pengaruh Perlakuan Media Tumbuh Terhadap Perkecambahan Benih Kayu Merah (Pterocarpus Indicus Willd)

Pterocarpus indicus Willd (Kayu Merah) is a straight bole hardwood plant that is easily grown in tropical areas such as Indonesia. In the East Nusa Tenggara Province, this plant is becoming rare which results in an effort of development and conservation of the species by the government through plant propagation. One of the ways of conserving the plant is through plant propagation. Problems faced in the propagation method through nurseries are breaking the dormant periode of kayu merah and finding the right media. The aim of this research is to understand the influence of treatment of growth medium in the kayu merah's germination. This research used completely randomized design with various treatments such as sand, black soil, bokasi, soil : sand (3:1), soil;sand;bokasi (3:2:2), soil:sand (1:1), soil:sand:bokasi (1:1:1) and soil:fertiliser (1:1). Every treatment was redone three times. The analysis used was analysis of varians followed by Significant difference test. The results showed that the highest successful of germination was the treatment using sand as the medium because of the good drainage so that the moisture level was optimum. On the other hand, the lowest was the treatment using bokasi as the medium because of the high moisture level which resulted in the decay of the seeds of kayu merah

SEBARAN SPASIAL KONDISI LINGKUNGAN HUTAN MANGROVE DI PESISIR PANTAI KOTA KUPANG

Mangrove is a specific ecosystem, which commonly is in the small wave beach or covered from wave beach area, affected by the sea tidal and water fill from the land. The purpose of this research is to know the spatial spread of the mangrove habitat environmental factor (salinity, mud thickness and slope) at the Kupang seashore  ( Paradiso, mangrove tourism and Oesapa). The salinity condition of  the mangrove forest at Paradiso is low up to medium category, the mud thickness is slight, thick and very thick. The slope is 2%-2,66%. At the mangrove tourism location, the salinity is varied from the dominant range value 23,33% and 24,66%, mud thickness is 10,88 cm up to 51,33 cm, and the slope of 1%-3%. At Oesapa mangrove forest location, the salinity is between 10%-18%, the mud thickness is 21,55 cm – 49,22 cm, and the slope is 2%-3%.

PENERAPAN MODEL AGROFORESTRI PADA KELOMPOK TANI HUTAN FETOMONE DI DESA SILLU KECAMATAN FATULEU KABUPATEN KUPANG

The Government of Eastern Nusa Tenggara province is currently facing the problem of an increasing size of critical land as well as decreasing availability of clean water which occurs in most of the landscape of Timor island. The increasing size of critical lands resulted from biophysical conditions, socio-economic and cultural situations which related to land use as the main factor for production, as well as the policy implementation that did not consider sustainability. One of the largest critical land can be found in Sillu village which is located in Fatuleu District in Kupang Regency. To overcome this critical land problem, an appropriate Agroforestry model is set to be developed and implemented. This community service aims to overcome the critical area in Sillu village and to increase the community’s well being through the implementation of an Agroforestry model specifically for the Fetomone Forest-Farmer group. Following methods were used: (1) site survey and family approach towards local community through head of the village, head of hamlets, and chair of Fetomone Forest-Farmer group; (2) Focus Group Discussion were conducted with head of the village and chair of Fetomone Forest-Farmer group to developed an activity plan including modelling design that will be used; (3) Community sensitization regarding socio, ecology and economic benefit of agroforestry system through lecture and discussion; and (4) Training in making agroforestry’s plot. Focus Group Discussion resulting in modelling design of Agrosilvopastural with alley cropping pattern. 53 local communities participated in community sensitization resulting in 96.2% understanding the socio, ecology and economic benefit of agroforestry system. 37 participants from Forest-Farmer group were included in the agroforestry’s plot making trainiing. Our 3 months post planting monitoring showed that 86.48% of them have been implemented the design on their own agricultural land.  ---  Permasalahan yang dihadapi pemerintah NTT adalah peningkatan  luas lahan kritis dan ketersedian air bersih yang terjadi pada sebagian besar daerah yang berada pada bentangan Pulau Timor. Peningkatan luas lahan kritis merupakan kesatuan yang bersifat simultan antara kondisi biofisik, sosial ekonomi dan budaya yang berkaitan dengan pemanfaatan lahan sebagai faktor produksi utama, serta penerapan kebijakan yang kurang mempertimbangkan kelestarian. Salah satu  daerah yang memiliki lahan kritis yang cukup luas adalah Desa Sillu yang berada di Kecamatan Fatuleu Kabupaten Kupang. Untuk mengatasi masalah tersebut, tim pengabdian menerapkan model agroforestri. Tujuan pengabdian adalah untuk mengatasi lahan kritis di Desa Sillu dan meningkatkan kesejahteraan masyarakat melalui penerapan model agroforestri di Kelompok Tani Hutan Fetomone. Metode  yang digunakan adalah 1) survei lokasi dan metode pendekatan kekeluargaan dengan masyarakat lokal melalui Kepala Desa, Kepala Dusun, dan Ketua Kelompok Tani Fetomone, 2) Metode Focus Group Discusion (FGD) dengan Kepala Desa dan Ketua Kelompok Tani Fetomeno untuk menyusun perencanaan kegiatan termasuk rancangan desain model yang akan digunakan, 3) Penyuluhan kepada masyarakat tentang manfaat sosial, ekologis, dan produktif (ekonomi) dari sistem agroforestri  dengan metode ceramah dan diskusi, 4) Pelatihan pembuatan demplot agroforestri. FGD menghasilkan desain model agosilvopastural dengan pola tanam alley cropping. Penyuluhan melibatkan 53 masyarakat dan  hasilnya 96,2% memahami manfaat sosial, ekologis, dan produktif (ekonomi) dari sistem agroforestri. Pelatihan pembuatan demplot melibatkan 37 anggota KTH dan hasil monitoring setelah 3 bulan kegiatan menunjukkan bahwa 86,48% sudah menerapkan model tersebut di lahan milik pribadi

The Physiochemical Condition of Mangrove Ecosystems in The Coastal District of Sulamo, Kupang, East Nusa Tenggara, Indonesia

Various rehabilitation and restoration of mangrove forests have been done, but there have not been any significant results. The main reason for the various failures in this activity is that the effort is not based on scientific data such as the suitability of the physicochemical conditions of mangrove habitats along the beach coast of  Sulamo District. The purpose of this research is to analyze the condition of salinity, the thickness of mud, and the beach slope of the selected mangrove locations Oeteta, Pariti, Beringin, and Pitai beaches.  The salinity conditions show variations, ranging from 19 ppm to 42.33 ppm. The thickness of the mud shows the highest value at 79.11 cm and the slope of mangrove coastal 1–4%. This research shows that the condition of the mangrove ecosystem in the coastal district of Sulamo is still suitable for mangrove growth. This research provides a basic overview of mangrove ecosystem conditions located on the beach coast of the Sulamo district as the basis for planning rehabilitation programs and mangrove restorations in the research area

Competition Influences Tree Dimension, Biomass Distribution, and Leaf Area Index of Eucalyptus Urophylla in Dryland Ecosystems at East Nusa Tenggara

Competition is one of the important factors that determine the productivity of forest stands. However, the effect of competition on the growth dynamics at the individual tree level is rarely documented. This study investigated the influence of competition on the tree dimension, biomass, distribution, and leaf area index (LAI) of Eucalyptus urophylla established in dryland ecosystems in East Nusa Tenggara. Data collection was conducted by N-tree sampling method with the number of center points reaching 36 units. The competition among trees was quantified using Hegyi index. Several parameters were measured to describe tree characteristics, including diameter, height, aboveground biomass, and LAI. The results demonstrated a significant influence of competition on the tree dimension, biomass distribution, and LAI of E. urophylla. The individual tree performance declined along with the increase in competition. By contrast, the increased competition gradually improved the relative contribution of branch biomass to the total aboveground biomass. The exponential model best described the linkage between competition and the tree characteristics of E. urophylla in the study site. Referring to these findings, this study concluded that the growth dynamics of E. urophylla at the individual tree level in dryland ecosystems is substantially influenced by competition. © University of Montenegro.

Species Composition and Carbon Stock of Rehabilitated Mangrove Forest in Kupang District, East Nusa Tenggara, Indonesia

Since 1994, the community around the mangrove forest in Kupang district, East Nusa Tenggara Province, Indonesia, has rehabilitated the mangrove forest. Unfortunately, almost three decades of the success story of mangrove rehabilitation has not followed appropriate documentation on biodiversity and potential carbon stock. This research aimed to describe the species composition and estimate the carbon stock of rehabilitated mangrove forests. Forty-five sampling plots were distributed using purposive sampling based on mangrove zonation (distal, middle, proximal) and year of rehabilitation (2004, 2006, 2008). The findings revealed that there are ten mangrove species. Two species, namely Avicennia marina and Sonneratia alba, showed a high importance value index. The average aboveground carbon stock was 454.712 t/ha, distributed in seedlings, saplings, poles, and trees at 0.04%, 2.41%, 51.61%, and 45.94%, respectively. Mangrove rehabilitation in Kupang district, East Nusa Tenggara Province, has successfully increased the richness, heterogeneity, and carbon stock
