Abstract

Critical land currently refers to a number of areas that are significantly unproductive as a result of inadequate management and utilization of soil and water conservation requirements. Critical land is land inside and outside the forest area that has declined in function. Das is a land area bounded by mountain ridges topographically, which functions as a natural reservoir to collect and store rainwater. To identify critical land, weighting and scoring were carried out on several critical land parameters including land cover, slope, and erosion hazard level, which were then overlaid and produced a critical land map. From this research, it was found that Wimbi Sub Das has a distribution of critical land dominated by not critical with an area of 129 ha or with a percentage of 7.12%, potentially critical with an area of 628 ha or with a percentage of 34. 64%, critical with an area of 821 ha or with a percentage of 42.28%, critical with an area of 221 ha or 12.19%, and very critical with an area of 14 ha or 0.77%, Based on the table overlay results show that Sub Das Wimbi is dominated by the level of criticality of the land category with an area of 821 ha which on a global scale has reached an alarming value. So it can be concluded that Wimbi Sub Das shows a rather critical potential, where land with a rather critical potential has an area of 821 ha.

Abstract

Effective and sustainable management of Non-Timber Forest Products (NTFPs) plays an important role in supporting the local economy, reducing pressure on primary forests, and maintaining biodiversity. This research aims to determine the use of NTFPs and the economic value of NTFPs in Walatana Village, South Dolo District. The research was carried out by applying survey methods to respondents and observations, using an analytical approach to the use of Non-Timber Forest Products (NTFPs) resources. Respondents are residents of Walatanana Village who have interactions with forest resources. The general problem faced in this research is the lack of understanding and awareness of the community regarding the potential of Non-Timber Forest Products (NTFPs) in Walatana Village, South Dolo District. The research results show that the people of Walatana Village have utilized various types of NTFPs, including rattan, candlenuts, bamboo, honey and firewood. With the economic value of NTFPs reaching Rp. 515,484,000,- per year, of which rattan contributes Rp. 220,200,000,-, this research highlights the great potential of NTFPs in supporting the local economy. These findings emphasize the importance of involving the community in efforts to sustainably manage NTFPs, while increasing their understanding of the economic potential that can be generated. This research indicates the need for an educational and participatory approach to increase public awareness of the importance of NTFPs in the context of sustainability. This effort is expected to create a balance between the use of NTFPs as a source of income and maintaining the sustainability of forest ecosystems.

Abstract

This research aims to determine the effect of the dose of compost mixed with horse feces and plant spacing on the growth and yield of leek plants (Allium fistulosum L.). This research was carried out in October 2022 at the Agrotechnology Study Program Experimental Field and the Laboratory of the Faculty of Agriculture, University of Timor. The design used in this research is a two-factorial split plot design. The first factor is the use of organic fertilizer mixed with horse feces, consisting of 4 levels, namely: without horse compost, 30 t/ha horse compost, 20 t/ha horse compost, and 10 t/ha horse compost. The second factor is the planting distance, which consists of 3 levels: 15 cm x 20 cm, 20 cm x 20 cm, and 25 cm x 20 cm. There were 12 treatment combinations, repeated three times, so there were 36 experimental units. The results of the research showed that there was an interaction between the treatment of giving horse compost fertilizer and the planting distance on the observed parameters of soil moisture content and root volume. The combination treatment of giving a dose of horse feces compost of 30 t/ha and a planting distance of 20 cm x 20 cm resulted in the highest number of leaves. The appropriate dose of horse feces compost for cultivating spring onions is 20 t/ha. This is proven by the highest values obtained for the harvest index parameters: economic weight per plot, economic weight per hectare, temperature, and plant height. This is proven by the highest values obtained for the harvest index parameters, economic weight per plot, economic weight per hectare, temperature, and plant height.

Abstract

Soil is a part of the Earth's crust where living organisms thrive, composed of minerals and organic materials originating from weathering and sedimentation. The soil in Naiola Village is classified as entisol with a very thin soil solum (lithic), characterized by low organic content and a very low cation exchange capacity. Previous research, liquid organic fertilizer (POC) derived from tofu waste was applied to investigate the effects of concentration and application time on the growth and yield of mung beans. The main objective of this research is to determine several soil chemical properties of entisols after applying POC to mung bean plants in Niola Village, Bikomi Selatan Subdistrict, Timor Tengah Utara Regency. The research was conducted using a descriptive method with observational techniques. Soil samples were collected from two plots, namely the control plot (P0) and highest yield plot (P1), at the mung bean plantation and subsequently analyzed in the laboratory to obtain quantitative data. The analyzed parameters are; water content and soil pH. The highest water content was 0.23% and the highest pH was 7.70.

Abstract

Locust pests are one of the most critical pests in almost every region of Indonesia. This pest phenomenon occurs because biological and environmental factors influence it. The significant use of chemical pesticides can cause environmental damage. One of the alternatives in controlling locust pests is using biopesticides Metharizium sp. This study aimed to determine the effectiveness of Metarhizium sp. biopesticides against locusts. The method used in the study was a complete randomized design (CRD), with four treatments, repeated four times to obtain 16 experimental units M0: Without biopesticide Metarhizium sp.; M1: biopesticide Metarhizium sp. 20 ml + 80 ml distilled water; M2: biopesticide Metarhizium sp. 40 ml + 60 ml distilled water; M3: biopesticide Metarhizium sp. 60 ml + 40 ml distilled water. The study results showed that Metarhizium biopesticide significantly affected mortality and feeding activity at a dose of 60 ml Metarhizium biopesticide liquid + 40 ml distilled water (M3). The observations on day three show that Metarhizium biopesticide can kill the locust pests by slowly beginning to paralyze the power of movement and the power of eating activity, causing the locust pests to experience death. Symptoms on the body of dead pests range from blackish, black hardened, and white spots. This shows that Metarhizium fungus with a dose of 60 ml is the most effective treatment in controlling locust pests.

Abstract

Dendrobium tissue culture through somatic embryogenesis process is a solution for mass propagation. The concentration of PGR and the composition of basic media are important factors in somatic embryogenesis. This research aimed to obtain the best type of basic media and BA concentration for regeneration process through somatic embryogenesis on Dendrobium 'Gradita 31' orchid. This research used a completely randomized design with 3 replications arranged factorial. The first factor was the type of basic media, ½ MS and MS. The second factor was concentration of cytokinin BA 1, 2 and 3 mg/L combined with NAA 0.5 mg/L. Each experimental unit consisted of 2 culture bottles, each contained 2 explants. The data from each variable was analyzed using analysis of variance, and continued with the BNJ test at a significance level of 0,05. The results of the research showed that the type of basic media had no significant effect on all variables. Concentration 2 mg/L of BA gave the highest response to the variables of percentage of somatic embryo formation, number of SE per explant and number of shoots per clump.

Abstract

Gamma-ray irradiation on plant seeds can affect plants’ growth and biochemical content. The application of gamma-ray irradiation can improve the quality of plants. This research aims to investigate the effect of gamma irradiation on the germination, growth, and chlorophyll content of sengon. Sengon seeds were irradiated with gamma rays at 0 (control), 25, 75, 125, and 175 Gy dose. Sengon seeds germinated and rared for four months. The study used a one-factor, completely randomized design (CRD). The parameters observed were the germination percentage, seedling height, diameter, and chlorophyll content. The result showed that gamma irradiation treatment can increase seed germination. Seeds irradiated with a dose of 75 Gy had a higher germination percentage than the other doses. Gamma irradiation with a dose of 25-175 Gy had of height and diameter of the seedlings compared to the control. Seedlings irradiated with a dose of 125 Gy had a higher chlorophyll content than other doses. Seedlings irradiated with a dose of 75 Gy had lower chlorophyll content than other doses. Therefore, in further experiment dose of gamma irradiation 25-175 Gy can be used to improve seeds’ viability. To increase the height and diameter of the seedlings, further research is still needed to investigate the effect of other doses on the growth of the seedlings.

Abstract

ABSTRACT The research aimed to determine the effect of vertically split of the shallot bulbs size and atonic frequency on shallot growth and yield was carried out on field at the Faculty of Agriculture, Science and Health, University of Timor, using a two-factor Completely Randomized Design (CRD). The first factor is the size of the bulbs, i.e., small size (D1), medium size (D2), and large size (D3). The second factor is the frequency of Atonic PGR (plant growth regulator) application (1.5 mL/L water), i.e.; 1 (F1), 2 (F2), and 3 (F3) times. The results of the research showed that even though there was no interaction between treatments, the use of medium sized of shallot bulbs with the frequency of Atonic PGR application 2 times was optimal to increase maximum growth and yield, including: number of leaves, leaf area, fresh weight of the plant, fresh weight of the waste, and dry weight of the waste, and dry weight of the bulbs (41.20 g). The interaction resulted in the fresh weight of the plant (59.49 g) and the fresh weight of the bulb (48.90 g) higher than other treatment. Keywords:
