Abstract

Abstract : This study aims to explore the species richness of biodiesel-producing microalgae in the waters of West Nusa Tenggara to develop renewable energy source, environmentally friendly, and not compete in land use with the agricultural sector. Microalga  samples were collected from various waters in West Nusa Tenggara Province using the concentration method. Species determination   and data analysis of microalgae was carried out at the Biology Laboratory, University of Mataram to calculate the abundance of each species. The dominant species of biodiesel-producing microalgae were isolated and cultured by a closed culture system method. The oil content of the microalgae biomass produced was extracted by  a liquid-liquid extraction method using n-hexane as a solvent. The results show that of the 49 species of marine microalgae identified in the waters of West Nusa Tenggara, there are 12 species of microalgae which are biodiesel producers. Of the 30 freshwater microalga species, only 8 species of microalgae are producers of biodiesel. The microalgae community of marine waters of West Nusa Tenggara is dominated by Bacteriastrumdelicatulum, B. variance, Chaetocerosaffinis, C. liciniosum, C. lorenzianum, Gyrosigma sp., Oscillatoria sp., Pseudonitzschia spp., and Thalassionemanitzschicoides, while freshwater microalgae communities are dominated by Microcystis aeruginosa, M. incerta, Nostoc sp., Pediastrumboryanum, and Staurastumcristatum. The dominant types of biodiesel-producing microalgae isolated and cultured are Chaetocerosamini, Nannochloropsisoculata and Nitzschia spp. Each cell density of C. amini, N. oculata, and Nitzschiaspp in culture 7 days after isolation was 3,600,960,000,  4,375,360,000, and  3,368,640,000 cells / liter respectively  with oil content 34, 68, and 46%.

Abstract

Abstract : The need for environmental protection continues to increase, so exploratory studies of agents of polluted environmental indicators are becoming increasingly important. The advantages of using flowering plants for environmental bio-indicator studies include the availability of sufficient test material with their variations and the availability of different periods for sampling. Seven plant species were used to examine their suitability as bio-indicator for genotoxicity of polluted atmospheric environment in Mataram City by microspore analysis. This study was conducted with the aim of, 1) knowing the level of difference in the frequency of failure (abortiveness) of microspores between similar plants that grow in areas at risk of being polluted in the city and those growing in areas not at risk of being polluted outside the city of Mataram, and 2) find out what types of flowering plants, especially those in city parks that are suitable as bio-indicators of air pollution for Mataram City. The percentage of aborted pollens was calculated out of 50 to 300 observed pollen grains of each selected individual flowering plant. Sample of each plant species from every study area consist of ten plant individuals. Data were analyzed by use the Wilcoxon one way-test at a 0.05 to determine significance of difference in the percentage of aborted pollen grains from same plant species between in the risky polluted area and plant in the control area.  The results showed that Lantana camara L. is suitable as bio-indicator for atmospheric pollution in Mataram City or other cities that have a density of traffic flow of motorized vehicles around 100 vehicles per hour. Its percentage of aborted pollen grains is 1,62 ±  0,08 % in the risky polluted area,  and   1,21 ± 0,13 % in the control area. Others six observed plant spesies, i.e.  Acacia auriculiformis A. Conn. Ex Bth., Bauhinia acuminata L., Baugenvillea spectabilis Willd. Duranta erecta L., Ixora coccinea L. and Rosa hybryda Hort., each of them is not suitable as bioindicator for it. Their percentage of pollen abortiveness in polluted and not-polluted areas were not different, significantly.Keywords: Genotoxicity, Microspores, Polluted air environment

Abstract

Pest control is an essential aspect of rice cultivation. The golden snail (Pomacea speciosa) is one of the pests in rice fields. Damage to rice plants due to golden snail attacks has occurred in several provinces in Indonesia and several countries such as the Philippines, Thailand, Japan, and Malaysia. Various steps to control golden snails have been carried out, both mechanically, biologically, and chemically. However, each biological and mechanical control of golden snails is impractical to apply to very large rice fields. Meanwhile, the control of golden snails using synthetic molluscicides such as Brestan and Dimotrin is minimal because it can pollute the environment and cause the death of fish and the rice plant itself. To suppress the emergence of environmental pollution problems in overcoming this golden snail, natural molluscicides from plant materials are studied. Several plant species have been known to have anti-mollusk properties, one of which potentially is the Jayanti plant {Sesbania sesban (L.) Merr.}. This study aimed to evaluate the anti-mollusk performance of S. sesban for controlling golden snails, a pest of rice plants. The dry powder of S. sesban leaves was extracted in stages with a series of solvents of petroleum ether, chloroform, and ethanol to obtain an extract fraction that was selected as a mollucicide. Each extract fraction produced was tested for its toxicity to the gold snail, carp, rice germination, and rice plant growth. Data on the mortality of golden snail and carp fish, the percentage of germination inhibition, and rice growth were processed by probit analysis, respectively. The outputs of the analysis were LC50 of each extract fraction for golden snails and carp. The ratio of LC50 for golden snail with LC50 for carp indicated each extract fraction's physiological selectivity of anti-mollusk properties. The results showed that the highest lethal toxicity to gold snails was indicated by the extract fraction-ethanol, while to carp, it was indicated by the extract fraction-chloroform. Each extract fraction of S. sesban leaves did not inhibit the germination and growth of rice plants. The extract fraction- ethanol had the highest anti-mollusk selectivity compared to the other two fractions. Bioactive examination showed triterpene saponins from the extract of S. sesban leaves, with the highest relative levels in the ethanol fraction compared to the other two extract fractions.

Abstract

City parks, apart from having an aesthetic function as a place for recreation, also have an ecological function with vegetation components to soften the microclimate. Vegetation analysis was carried out in six city parks in Mataram City to determine the vegetation structure. Microclimate factors of the park, namely light intensity, air temperature and humidity inside and outside the park during the day and observations of sound attenuation at night have been carried out. Climatic data is carried out to determine the park's ability to reduce heat and air temperature, increase air humidity and reduce noise and determine the park's environmental discomfort index. Of the six urban parks observed in the city of Mataram, namely the parks of Ampenan, Malomba, Udayana, Sangkareang, Mayura, and Selagalas, it is known that there are three groups of vegetation structures, namely trees-shrubs, shrubs-trees, and shrubs. Vegetation with various compositions of life forms in each city park only controls 40 to 60% of the land area of the park. Urban parks in Mataram City have a low level of ability to soften the microclimate, which is below 5%. In reducing heat and air temperature, and increasing air humidity. City parks are also known to have a low ability to reduce noise. The city parks of Ampenan, Udayana and Sangkareang have an environmental comfort level equivalent to the discomfort felt by more than 50% of the population, while the Malomba, Mayura, and Selagalas parks have a level of comfort equivalent to the discomfort felt by less than 50% of the population. The existence of urban park vegetation is only able to reduce the discomfort index of 7 to 9%.

Abstract

The specific purpose of this study was to determine the stability of S. sesban insecticide during storage before application and its stability in water during application. The dry powder of S. sesban leaves was extracted using water as the single solvent. Bioassay of S. sesban leaf extract was carried out on cabbage caterpillars (Plutella xylostella larvae) and Diadegma semiclausum imago on cabbage plants using a variation of storage time design. Mortality data of P. xylostella larvae and D. semiclausum imago were respectively processed by probit analysis to determine LC50. The results showed that the insect repellent content of S. sesban leaves was a compound from the saponin group and was unstable during simplicia storage, extract storage and also unstable in water before and during application. Storage of S. sesban leaf simplicia from 1 to 3 months only slightly reduced the lethal toxicity of the extract to P. xylostella larvae (mortality from 95 to 80% or LC50 from 28.82 to 28.83 ppm), but after 6 to 12 months storage, the lethal toxicity decreased drastically (mortality was 12.5 to 1.25% and LC50 was 247.99 ppm until calculated). Storage of S. sesban leaf extract from 7 to 15 days had resulted in a sharp decrease in lethal toxicity to P. xylostella larvae (mortality 70 to 40% and LC50 34.05 to 59.43 ppm) and 30 days storage causes the insect repellent to be inactive. (mortality was only 1.25% and LC50 was unaccounted for). Exposure to a solution of S. sesban leaf extract for 24 to 48 hours caused a decrease in lethal toxicity to P. xylostella larvae (mortality 32 to 28% and LC50 62.63 to 64.85 ppm) and after the solution was stored for 72 hours, the insect repellent was almost no active again (mortality was only 1.25 and LC50 was unstoppable). All storage treatments of insect repellent from S. sesban leaves showed no significant difference in the effect of lethal toxicity on D. semiclausum imago. In all the results of the bioassays, the mortality of D. semiclasum was 0 to 1.25% and each of all LC50(s) was unaccounted for

Abstract

The study on the use of local natural materials as a source of insecticides is intended, among other things, to reduce farmers' dependency on using synthetic chemicals. This research was conducted to obtain the most selective insecticidal active ingredient from Sesbania sesban plant for controlling cabbage caterpillars, choose a target mode of action that has a safe impact on the environment, and determine insecticidal stability during storage of the material prior to application and its stability in water after application.  The dried powder of S. sesban leaves was extracted in stages using a series of solvents, namely hexane, DCM, ethanol and water, respectively.  Each of the extract fractions produced was tested for its lethal toxicity against Plutella xylostella larvae and Diadegma semiclausum imago. Each of mortality data were processed by probit analysis to produce LC50(s) to determine their insecticidal selectivity. Subsequent bioassays were carried out using extract-water of S. sesban leaves and the data were processed by probit analysis to determine their anti-ovipositor, ovicidal powers and anti-feedant properties against P. xylostella. The insecticidal stability of S. sesban was also studied according to variations in the storage time of the simplicia before extraction, the storage time of the extract before dissolution, and its stability in water during application. The data was processed using ANOVA. The results show that the insecticidal activity of the ethanol extract fraction of S. sesban leaves for controlling cabbage caterpillars was very selective, namely very toxic to P. xylostella but very less toxic to D. semiclausum. Against P. xylostella, S. sesban leaf extract has also been proven to significantly prevent oviposition, inhibit egg hatching and feeding activity. The insecticidal power of S. sesban did not decrease significantly during storage of the simplicia for less than three months and during storage of the extract for less than seven days. However, the toxicity of the extract solution decreased drastically after 24 hours of application

Abstract

Tomato (Lycopersicum esculentum Mill) is a horticultural crop that has high economic value and is widely used as a commercial product. Abundant tomato harvests make the price of tomatoes in Paok Pampang Village cheap. It was recorded that in July 2023, tomatoes have decreased in price from IDR 12,000 – IDR 22,000, down to IDR 3000 – IDR 4000 per kilo. With this low price, farmers sometimes leave their tomatoes in their fields, causing tomatoes that are ready to be harvested to rot and waste. The method used in this activity is a method in the form of practice that is carried out with several stages, including Activity Planning, Activity Preparation, and Activity Implementation. Next is the socialization of candied tomato products. This socialization aims to educate the public that tomatoes can have added value if converted into new products such as processed into candied tomatoes. The people of Paok Pampang Village are also enthusiastic about this candied tomato product. This can be seen through the questions raised during the socialization process

Abstract

The Sekotong area has natural charm and potential mining. This area is one of the preferred destinations for visits by local and foreign tourists. However, apart from that, the Sekotong area is also famous as a community gold mining area. Mining activities carried out still use traditional methods, which are very far from environmentally friendly principles, so they can have impacts, including causing a decrease in the quality of residential well water. This research was conducted to determine the water quality of residential wells around community gold mining in the tourist area of Dusun Selindungan Eleven well water samples were taken using a purposive sampling method based on the distance of the well to the source of gold mining waste disposal and are still used by residents to meet their daily needs. Physical, chemical and biological water quality parameters of water samples were investigated in the laboratory, except temperature and pH were measured directly in the field. Data for each water quality variable was analyzed to determine the pollution index. The results show that DO, TDS, content of phosphate, E. Coli bacteria and total coliforms in well water from the study area generally exceed quality standardsWell water in an area that is a different distance from the people's gold mining waste disposal site has each been contaminated with manganese and mercury, although it is still below quality standards.

Abstract

Flooding is the inundation of a flat area as a result of overflowing water from the surrounding area or an overflowing river. The largest river that crosses West Lombok Regency is the Meninting River. The Meninting watershed area as a catchment area has an area of 12,307.75 hectares. This research aims to identify and map flood-vulnerability areas in the Meninting Watershed. Data collection was carried out through a geographic information system (GIS) using overlay and scoring methods. The variables used to assess the level of flood vulnerability were land slope, soil type, rainfall, land cover, and geological aspects. The level of flood vulnerability is divided into three classes, namely not vulnerable, moderately vulnerable, and very vulnerable. The results show that of the 41 villages/sub-districts in the Meninting watershed, 34 villages/urban- villages with a coverage area of 8.21% were very vulnerable to flooding. The four villages that have the largest flood-vulnerable areas were the villages of North Ampenan (120.16 hectares), Midang (87.43 hectares), Dasan Griya (79.68 hectares), and Sesela (77.32 hectares). Around 56.24% of all villages/urban villages in the Meninting watershed were quite vulnerable to flooding and 35.55% of the area was not vulnerable.
