EFFECTS OF THE INTERACTION OF BUBBLE PLANTS AND THE MEDIA COMPOSITION OF PLANTSAGAINST THE GROWTH OF SANDALWOOD SEEDS (Santalum album Linn)

2024-07-02T14:04:23+00:00

Sandalwood (Santalum album Linn.) is a wood-producing forest plant in the East Nusa Tenggara province (NTT) which has great economic value and is an endemic type of species. The exploitation of the foam plant (Santalum album Linn) which is not offset by its conservation efforts causes the plant to be at risk of extinction. Candana (Santalum album Linn) is also a tree whose seed germination is relatively slow due to the thickness of its skin which inhibits the entrance of water inhibitively so that the germinating process takes a relatively long time Giving ZPT GA3 is believed to help the growth because it contains plant hormones that are available both endogenously and exogeneously and giving the composition of the growing medium can also help to nourish to accelerate plant production. The method used in this study is Complete Random Design (RAL) 2 factors, namely factor A concentration GA3 and factor B composition of soil, sand, chicken stool, cow stool with 9 combinations of each combination of such treatment was repeated 3 times so that 27 experimental units were obtained. Each experimental unit uses 100 mold seeds so the total seed required for 27 experimental units is as much as 2,700 mold seed. The results of the research showed that the concentration of GA3 80% with a cattle stool growing medium of 2 kg, sand 1 kg and soil 1 kg can increase the percentage of spruce, the rate of germination, the wet weight and dry weight of mushroom seed plants (Santalum album Linn).

THE ROLES OF VEGETATION IN OPEN GREEN SPACES IN KUPANG EAST NUSA TENGGARA

2024-06-30T13:30:48+00:00

Open green spaces are crucial for urban landscapes, providing huge benefits such as biodiversity conservation and promoting human health. They can be found in various forms like parks, gardens, and natural reserves. In Indonesia, open green spaces are a trend and prioritized by local authorities because the increasing number of buildings, roads, and vehicles in urban areas that potentially decrease air quality due to contamination of dust, CO_2,and other pollutants. A study on the vegetation composition in Kupang open green spaces is needed to understand its potential benefits and serve as a baseline for developing extensive open green spaces with specific vegetation composition. The results reveal that from the 26 plant species that planted to green the areas, over 69% vegetation is suitable to be planted while 31% vegetation is moderately suitable. The majority of these plants are from the Fabaceae, with 34% of the vegetation in the green areas, followed by Anacardiaceae at 31%. The remaining species are moderately suitable, with Verbenaceae having 7% and the rest at 4% each. The vegetation in these areas plays various roles, such as filtering solid particles, absorbing cement dust, suppressing noise, reducing acid rain impacts, increasing water infiltration, improving aesthetics, and conserving groundwater. These roles are crucial for Kupang's urban environment, which faces potential environmental issues such as air pollution, solid particle pollution, drought, and noise pollution. The results indicate that the vegetation used to green the areas can create significant roles for the urban environment and the people.

IDENTIFICATION OF FRUIT FLIES ON BITTER MELON PLANTS (Momordica charantia L.) IN TUNAS MUDA BURAEN FARMING GROUP BURAEN VILLAGE, SOUTH AMARASI SUBDISTRICT, KUPANG DISTRICT

2024-07-01T13:30:38+00:00

This research aims to determine the types of fruit flies that exist in bitter
melon cultivation belonging to the Tunas Muda Buraen Farmers Group, Buraen
Village, South Amarasi District, Kupang Regency. This research was carried out on
land belonging to the Tunas Muda Buraen Farmers Group, Buraen Village, South
Amarasi District, Kupang Regency and the Plant Pest Laboratory, Faculty of
Agriculture, Nusa Cendana University in August-November 2024. The fruit flies
obtained from the traps were Bactrocera dorsali, Bactrocera papayae, and
Bactrocera carambolae. However, the species obtained from rearing is the
Bactrocera cucurbitae species, this species is a different species from the existing
trap results. The different results are thought to be because the species obtained had
different hosts, or the main host was not the bitter melon plant. The second factor is
because the rearing activity does not use all the fruit that is attacked, thus giving the
possibility that the unused fruit has been attacked by fruit flies, and the last factor is
because the traps have been set early so there is little chance for other species to
attack the bitter melon plants. From these factors, it is proven that the B. cucurbitae
species damages bitter melon plants with the intensity of damage to bitter melon fruit
being expressed as light damage intensity with an assessment of 6.21%.

Lettuce cultivation on Inceptisol in the drylands of Timor Island is constrained by low
nutrient availability, especially nitrogen. The application of vermicompost fertilizer combined
with NPK Phonska fertilizer is expected to increase the availability of N and lettuce yields
through proper dosage settings. This study aims to obtain a combination dose of
vermicompost and NPK Phonska fertilizer that gives the best effect on the availability of N
and lettuce yield on Inceptisol in drylands of Timor Island. The research was designed in a
single factor experiment using a completely randomized design. The treatments tested were
the doses of combined vermicompost and NPK phonska fertilizers, namely: control/no
fertilizer application (P0); 20t.ha-1 vermicompost + 200kg.ha-1 NPK phonska (P1), 20t.ha-1
vermicompost + 400kg.ha-1 NPK phonska (P2); 30t. ha-1 landfill + 200kg.ha-1 NPK
phonska (P3); 30t.ha-1 landfill + 400kg.ha-1 NPK phonska (P4); 40t.ha-1 landfill +
200kg.ha-1 NPK phonska (P5); and 40t.ha-1 landfill + 400kg.ha-1 NPK phonska (P6). Each treatment was made in 3 replications so that 21 experimental units were obtained. The results
showed that: (1) all treatments of combined doses of vermicompost and NPK Phonska
fertilizers gave values of soil N-total content and plant tissue N that were significantly
different from the control treatment, but no significant differences were found between the
doses of combined vermicompost and NPK Phonska fertilizers; (2) the treatment of 40t.ha-1
vermicompost + 400kg.ha-1 NPK Phonska produced the highest fresh weight per lettuce
plant which was not significantly different from the treatment of 40t.ha-1 vermicompost +
200kg.ha-1 NPK Phonska but significantly different from all other treatments. There was no
best combination dose treatment of vermicompost and NPK Phonska fertilizer in this study.

ETHNOPHARMACOLOGICAL STUDY ON THE POTENTIAL HERBAL PLANTS IN THE TRADITIONAL MARKETS OF KUPANG EAST NUSA TENGGARA

2024-07-01T15:49:18+00:00

Indonesia, a tropical forest country with enormous biodiversity, has a significant potential for herbal plants, which can be used as medicines and natural remedies. These plants are abundant in densely forested areas and can also be found in traditional markets, contributing to economic growth and preserving traditional culture. Traditional markets offer a variety of herbal plants, including ginger, turmeric, galangal, lime, and pepper, which have been used for centuries in Indonesian cuisine. Local communities can easily access these affordable medicinal plants, especially those with limited access to modern health services. However, limited studies have explored the variety and potential economic market values of these plants, particularly in Kupang East Nusa Tenggara. Therefore, we conducted an etnopharmacological study on the potential herbal plants in the traditional markets of Kupang. 25 herbal plant species from 14 families in four traditional markets in Kupang revealed their potential for health and economic benefits. These plants contain various pharmacological components, including anti-oxydant, anti-bacteria, anti-inflammation, and anti-viral properties. Along with health benefits, the circulation of these plants in the traditional markets in Kupang can not only create economic benefits but also can also promote the preservation of indigenous cultural heritage and the sustainability of traditional practices as well as biodiversity conservation.

ASSESSING MANGROVE HEALTHINESS LEVEL OF MANGROVES ALONG THE OESAPA COASTLINE USING THE MONMANG APP

2024-06-30T13:30:51+00:00

Despite being considered one of the most important ecosystems on earth, mangrove forests have been threatened by humans, which can lead to global mangrove loss. Therefore, the restoration of mangroves on both a global and a certain spatial scale is required. One of the mangroves that benefit local communities ecologically is occurring along the Oseapa coastline in Kupang, East Nusa Tenggara Province. In order to successfully restore degraded mangroves, a comprehensive assessment of their healthiness level is necessary. Hence, the MonMang Android-based application developed by BRIN can be used to collect the data within observation transects and plots and then analyze the healthiness level. The Oesapa mangrove forest is a habtat for 8 mangrove species belonging to 5 families. They are Avicennia alba, Avicennia marina, Ceriops tagal, Lumnitzera racemosa, Sonneratia alba, Rhizopora mucronata, Rhizopora apiculata, and Xylocarpus sp. The MonMang application reveals that the overall mangrove healthiness is at Moderate level. In addition, we found that Site 2 has the lowest Mangrove Health Index (MHI) value, with an average of 35.00-65.00. This indicates that the reforestation is strongly suggested in this area. It can be prioritized for restoration efforts to improve healthiness and mangrove cover. The spatial re-plantation also needs to be conducted in other locations within Oesapa mangrove forest which possess Moderate level of mangrove healthiness. Moreover, stump occurrence and garbage coverage vary across the observation sites. Site 2 has the highest proportion of stump occurrence, possibly due to past mangrove dieback. Garbage coverage varies across the sites, with plots closest to seaward having the lowest coverage and those close to settlements having the highest. These findings highlight the need for further restoration efforts to maintain the sustainability of mangrove forest along the Oesapa coastline.

THE EFFECT OF SEVERAL HOST TYPES ON THE GROWTH OF SANDALWOOD (Santalum album) SEED FROM TWO DIFFERENT SEED SOURCES

2024-07-01T17:23:46+00:00

Sandalwood (Santalum album) has hemiparasitic properties with a character as a root parasite,
which is characterized by the formation of haustoria to connect sandalwood roots with host plant
roots. It is this hemiparasitic nature that causes sandalwood during the growth period to require the
presence of other plants around it which act as hosts. Many sandalwood seedlings fail to germinate
or grow very slowly due to being planted without a host.
This study aims to determine the growth effect of sandalwood seedlings from different seed sources
on various types of hosts. The method used was a one-factor Completely Randomized Design
(CRD), namely the influence of host species. Host types consist of Lamtoro, Kaliandra, Turi, and
Moringa. The source of the seeds came from South Timor Tengah Selatan
(X) and Alor Regency (Y).
The results of the study based on the analysis of variance showed that the treatment of host
plants had an effect on the growth of sandalwood. The results of the analysis of variance for each
observation parameter also showed that the average growth rate was not much different between the
two seed sources, but in general the growth of sandalwood seedlings from South Central Timor
district had a higher average value than that of seed sources from Alor. So if we look at it based on
the average value of growth, the growth of sandalwood seedlings from Timor Tengah Selatan is
better than the growth of sandalwood seedlings from Alor.

SURVEY OF HABITAT CHARACTERISTICS AND FOREST BEEHIVE TREES OF Apis dorsata SPECIES IN MUTIS TIMAU PROTECTED FOREST AREA

2024-07-01T17:29:49+00:00

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.

PENGARUH PEMBERIAN PUPUK ORGANIK KOTORAN SAPI DAN MULSA PLASTIK TERHADAP PERTUMBUHAN DAN HASIL CABAI RAWIT (Capsium frutescens L.)

2024-07-03T01:39:56+00:00

This research was carried out from March to July 2023 in the Fatukoa-Maulafa sub-district of Kupang, with the aim of determining the response to growth and yield of cayenne pepper plants (Capsium frutescens L.) due to the influence of doses of cow dung manure and the application of plastic mulch. This research is a factorial research using a Randomized Group Design (RAK). The factors tested consisted of the plastic mulch factor (M) with 2 levels, namely without mulching (m0) and black plastic mulch (m1) and the dose of cow dung organic fertilizer factor (K) consisting of 4 levels, namely without giving a fertilizer dose. cow manure (k0), cow manure organic fertilizer dose 10 tons ha-1, cow manure organic fertilizer dose 20 tons ha-1, and cow manure organic fertilizer dose 30 tons ha-1, so there are 8 treatment combinations. Each treatment combination was repeated 3 times. The data obtained was analyzed using variance analysis, and if the results of variance analysis showed a real effect, a test was carried out using the advanced Duncan Multiple Range Test (DMRT) at 5% level. The results of this study indicate that the interaction of the dose of cow dung manure with plastic mulch has a significant effect on the average LAB, average LTR, and weight of cayenne pepper fruit per plant, but the interaction has no significant effect on plant height, number of productive branches, and number of chili fruit per plant.
