Abstract

Long bean (Vigna sinesis L.) is a horticultural plant that is easy to cultivate. Cultivation of long bean plants certainly has several factors that can reduce production yields such as environmental factors, pest attacks, and diseases. This study aims to determine the pests and diseases that generally attack long bean plants and the symptoms they cause. This study used direct observation method (Systematic sampling) to determine the percentage of pest and disease attacks on long bean plants. From the total number of plants in the location, 5 plant samples were taken to be observed. Based on the pest and disease identification research that has been carried out, it was found that some of the symptoms that arise due to pest/disease attacks on most of the long bean plants were found. Symptoms that appear include damage to flower buds and leaves with holes caused by black ladybugs (Brachyplatys sp.); leaf curl, leaves and stems turn black due to aphids (Aphis craccivora); jagged leaf edges, and holes caused by grasshoppers (Oxya sp.) and lasiocampidae caterpillars; thickening of the leaf veins on young leaves, leaves shrinking caused by Bean Common Mosaic Virus (BCMV); The leaves turn yellow and the bone blanching occurs due to the Mungbean Yellow Mosaic Virus (MYMV).

Abstract

The area at the research site has a mangrove community that is experiencing disturbances due to the conversion of land into ponds. Therefore, the purpose of this study was to assess the actual condition of mangrove vegetation after land conversion. The method used in this research is a survey and the sampling point is determined randomly (random sampling). Furthermore, observations were made on two existing mangrove blocks, namely the Natural Block and the Rehabilitation Block. Observation plots were placed randomly in the Natural Bok and Rehabilitation Block. Randomization was carried out on the regional map by making a grid measuring 10x10m and numbered. The data were analyzed using the analysis of the diversity index value (Shannon-Wiener), the evenness index (Evenness), the proportion of vegetation at each growth level and the pattern of vegetation distribution (Morisita Index). The results showed that the value of species diversity in the Natural Block was 0.95 and the Rehabilitation Block was 0.99. This value is included in the category of low diversity. The evenness index obtained a value of 0.49 in the Natural Block and 0.45 in the Rehabilitation Block. This value indicates that the distribution of the number of individuals in each species is not evenly distributed. Vegetation is dominated by Trees (in the Natural Block) and Saplings (in the Rehabilitation block). The vegetation in the Natural Block is older than the Rehabilitation Block. Meanwhile, based on the value of the Morisita index, the distribution pattern of mangrove vegetation in the study area is included in the cluster category.

Abstract

Musa paradisiaca cv Haji is a local banana of Lombok that has a longer shelf life. The determination of the haji banana genome still uses a scoring method based on morphological character. Clarification of ploidy levels and genome types can be done using chromosome analysis. The initial information needed to perform the karyotype analysis is identifying the cleavage time of M. paradisiaca cv Haji. Banana Haji on the island of Lombok has a different local name, so morphological identification of the haji banana accession is required. Morphological observations were conducted on three accessions of Haji bananas from different cultivation sites. Identification of the time of mitosis cleavage is made by the Squash method. The results showed a uniform synapomorphic character in the haji banana accession. The characters include the aspects of pseudostem (normal), shiny pseudostem, imbricate young bractea (young bractea slightly stacked), red inner bractea, straight ovary, and no pigmentation on the stylus. The autapomorphic character of Haji banana accession in this study included inside the pseudostem of the red-green, the position of horizontal fruit bunches, a fair amount of wax on the surface of the lower leaf, and the petiole of the lower leaf in pink. There are morphological character differences in Haji cultivar accession on pseudostem color and tepal color pigmentation. The time of mitosis division in Haji bananas, especially the prophase stage - metaphase from 06.38 - 07.38 Wita. The results obtained in this study can be used as a foundation to conduct karyotype analysis of Musa paradisisaca cv Haji.

Abstract

Processed meat products that are common and much preferred by the consumers are sausages and beef meatballs. This processed product has the disadvantage that it has a high-fat content, causing faster oxidative damage. This study aims to observe differences in the nutritional value and antioxidant activity of meatballs and sausages from Bali-beef and Lamtoro-beef. The main research material is fresh Bali-beef and lamtoro beef using several chemicals and laboratory equipment related to proximate analysis and antioxidant testing. The study was designed based on a Completely Randomized Design with 4 treatments and 3 replications and continued with Duncan's test SPSS version 16 programme. The results showed that the highest crude protein content was found in lamtoro-beef with lower fat content, water content, and ash content compared to fresh Bali-beef. Meatball and sausage products with the raw material of lamtoro-beef were not significantly (P>0.05) had a higher crude protein content than meatballs and sausages with the raw material of Balin-beef. The antioxidant activity of fresh Bali-beef and its processed products (meatballs and sausages) was not significantly (P>0.05) higher than the antioxidant activity of lamtoro-beef. Conclusion: Lamtoro-beef and its processed products in the form of meatballs and sausages have a higher protein content with lower fat content, water content and ash content compared to fresh Bali-beef. Meatball and sausage products made from fresh beef were not significantly (P>0.05) had higher antioxidant activity than lamtoro-beef.

Abstract

Bacillus thuringiensis is one of the bacteriae species that be able to kill insects. The latest research showed that the cell plasm of this bacteria contains crystalline protein with natural insectisides properties. Therefore the insecticidal effect of this species on insects which is decreasing cultivation plant production is interest to be examined. One of the insect species that are well-known causes of loss of farm production in fruit flies (Drosophila melanogaster). Therefore this research is designed to isolate, purify, and thenassess Bacillus thuringiensis toxicity against Drosophila melanogaster as animal treatment. Bacillus thuringiensis was successfully isolated from soil of  cows cage by using Lauria Bertani medium contain 0,25 M buffer solution Acetic, pH 6.8. The result shows that Bacillus thuringiensis isolate is a gram-positive bacteria. Position of endospore is located between the middle and the end of the cell (subterminal spore). Toxicity test was conducted by mixing 0.5 g/L, 1 g/L, 2 g/L, 4 g/L of pure Bacillus thuringiensis isolate into  Drosophila melanogaster medium. The treatments effect were monitored for 15 consecutive days. Toxicity test shows that the treatment has no significant effect on the treated animal mortality. This result shows that crystal-producing Bacillus thuringiensis strain isolated from cows cage soil do not have insecticidal properties for Drosophila melanogaster. It is concluded that Drosophila melanogaster is a non-target species of Bacillus thuringiensis.

Abstract

Mustard is a vegetable with high economic value, including mustard pakcoy (Brassica rapa subsp, chinensis), mustard petsai (Brassica chinensis L), and white mustard (Brassica rapa subsp, pekinensis). To meet consumer needs, it is necessary to increase the production of mustard through organic farming by implementing an agricultural system that utilizes water hyacinth in the form of liquid organic fertilizer. Water hyacinth is an aquatic weed so an alternative is needed to reduce its population by using it as a liquid organic fertilizer with a bio-activator Trichoderma sp. The purpose of the study was to measure plant height, number of leaves, leaf width, and wet weight of mustard pakcoy, mustard petsai, and white mustard. The design of this study used a single factor RAL, namely giving water hyacinth POC with bio-activator Trichoderma sp on 3 types of mustard, with 3 levels, namely A = 32 ml/L (mustard pakcoy), B = 32 ml/L (mustard petsai), C=32 ml/L (white mustard) which was repeated 5 times. Research proves that giving water hyacinth POC with bio-activator Trichoderma sp 32 ml/liter has a significant effect on the height and width of white mustard leaves. For the number of leaves and wet weight, giving water hyacinth POC with bio-activator Trichoderma sp 32 ml/liter had a significant effect on mustard pakcoy compared to other mustards. This means that POC with bio-activator Trichoderma sp can be used as an environmentally friendly liquid organic fertilizer, especially for mustard pakcoy and white mustard which can stimulate plant growth and productivity.

Abstract

Borneo is the second-highest diversity island for Nepenthes, with approximately comprising 23 species that were spread on this island. Species found on lowland to highland with variety habitat and ecological types. Tanjung Selor is the capital city of Bulungan Regency, North Kalimantan. Nepenthes distribution in these areas has never been reported, particularly in the heath forest. The study was conducted to report the floristic of Nepenthes in Tanjung Selor. We used a desktop study and field exploration on heath forest of Tanjung Selor in 2019 with rapid biodiversity assessment method. The preliminary report of Nepenthes in Bulungan are presented with species description, ecology, threats, illustration, and a brief disscusion regarding the species. We reported six wild species and one natural hybrid of Nepenthes based on exploration. Nepenthe’s habitat is in an open area, roadside, and heath forest vegetation. The threats are higher from habitat degradation and land conversion to agricultural land or non-agricultural uses.  In this paper, we mentioned Nepenthes fusca growth in lowland habitat, commonly found in highland.

Abstract

Fertilizers are nutrient sources that have a role in determining the growth and production of a plant. Fertilization can be done using organik fertilizers and inorganik fertilizers. The use of combination of organik fertilizers and inorganik fertilizers is carried out to reduce the risk of damage to the soil structure due to the use of inorganik fertilizers continuously. This study aims to determine the effect of applying vermicompost and NPK fertilizers and it’s combinations and know the most effective number of doses of vermicompost and NPK fertilizers for the growth of green mustard plants. The design used is a complete randomized design of 2 factors, namely the dose of vermicompost with 5 levels of doses and doses of NPK fertilizer with 4 levels of each dose in 4 replications. The treatment of vermicompost consisted of 0 gr, 75 ml, 150 ml, 225 ml, and 300 ml. The treatment of NPK fertilizers consisted of 0 gr, 0.4 gr, 0.6 gr, and 0.8 gr/100 ml water. The data were analyzed using ANOVA test. The results showed that the treatment of vermicompost and NPK fertilizers and combination did not have a significant effect on the growth parameters of green mustard plants, namely plant’s height, number of leaves, leaf area, wet weight and dry weight of plant.
