Abstract

Nutritional problems in Indonesia and in developing countries in general are still dominated by the problem site, namely the problem of lack of protein energy (KEP), Iron Anemia, problems due to iodine deficiency (IDD), vitamin A deficiency problems (KVA). Iron anemia is the most common in the community, the occurrence of Iron Anemia can be caused by several factors including iron content in daily food, very low absorption of iron from food, the presence of parasites in the body, and loss of blood due to accidents or accidents. surgery due to illness. Therefore, the researchers tried to examine the effect of Incubation and Non-Incubation on the examination of Hemoglobin levels using the Sahli Method using the Experimental Method which is Cross Sectional. This study aims to determine whether there is an effect of incubation and non-incubation on the results of examination of hemoglobin levels using the Sahli method at Sedau Public Health Center, Narmada District, West Lombok, NTB.

Abstract

Bacillus thuringiensis is one of the bacterial species that produces a bioinsecticide known as Bacillus thuringiensis toxin. The purpose of this study was to determine the toxicity of Bacillus thuringiensis var israelensis to Bactocera papayae larvae. Larvicidal activity was calculated based on the percentage of total larval mortality after exposure to Bacillus thuringsiensis var israelensis spores for 24, 36, 48 hours. The results showed that the mortality of Bactocera papayae larvae instar III-IV ranged from 0-30% which was challenged with 106-108 spores/ml. Bacillus thuringiensis var israelensis exposed to Culex sp mosquitoes can kill up to 100% at a concentration of 104 spores/ml.

Abstract

Water is a means of improving the health status of the community, its quality needs to be maintained so that it is still beneficial for human life and other living things and water control is still carried out. Improving the quality of drinking water by managing it is absolutely necessary, especially if the water comes from surface water. South Rarang Village is deemed necessary to conduct research on the concentration of lime (CaCO3) in well water in South Rarang Village because it is seen that when the community boils water taken from the well, scale develops in the water heating boilers. The sample in this study was part of the wells of the people of South Rarang Village, Terara District, East Lombok Regency. The sampling criteria used by the researchers in this study were based on the location and location of the wells in each hamlet in Rarang Selatan Village, Terara District, East Lombok Regency. Based on the results of testing well water in Rarang Selatan Village, Terara District, East Lombok Regency at the Lombok Island Public Health Laboratory, it can be concluded that the average lime content in each well in South Rarang Village has an average of 432 mg/liter

Abstract

Meniran (Phyllanthus niruri L) is a type of herb from the Euphorbiaceae family that grows wild in damp and rocky places, such as bushes and soil among the grasses, but has medicinal properties. Meniran also has potential as an antibacterial because it contains many bioactive components such as alkaloids, flavonoids, tannins, and saponins. Gram negative bacteria such as Salmonella sp. and gram-positive bacteria such as Propionibacterium acnes. Fusarium oxysporum is one of the soil-borne pathogens that can attack horticultural crops so that it can affect the decline in plant productivity. Fusarium oxysporum is a pathogenic fungus that causes a disease known as fusarium wilt disease. This fungus is found in the soil by forming three kinds of spores, namely microconidium, macroconidium and claimidospore. This study aims to determine the inhibition or antagonist of meniran leaf extract (Phyllanthus niruri L.) against fusarium sp. meniran against fusarium fungus.

Abstract

Bay leaf (Syzygium polyanthum) is a plant that is easy to grow in the tropics and is often found in forests and in home gardens. Bay leaves contain ingredients that can inhibit the growth of fungi such as flavonoids, tannins, and essential oils that have antibacterial and antiviral activity. The purpose of this study was to determine the minimum inhibitory level of ethanolic extract of bay leaf (Syzygium polyanthum) at a certain concentration that could inhibit the growth of the fungus Fusarium sp. Fusariun sp. Is one of several groups of fungi that can cause disease in plants. This fungus is also included in the turberculariaceae family because the fungus forms a fruiting body that forms a conidium called a sporodocium. Fusarium mushrooms have diversity, namely F. oxisporum, F. camptoceras, F. conentricum, F. musarium, F. proliferatum, F. semitectum, F. compactum, F. thapsinum, F. verticillioides, and F. subglutinans. This study used an experimental method with a completely randomized design (RAK). The parameter used is the clear zone around the disc paper. The results obtained that bay leaf extract is able to inhibit the growth of fungi and has the potential as an alternative antifungal material.

Abstract

The Fusarium spcan infect plants and cause withered diseases, it is a pathogenic fungus that greatly harms and causes losses from crop failure in the pepper plnt and various other fungus plnts to infect nd cause losses and crop failure by 50 %. The diseases strikes, the plant from the seedling age to adulthood. The reed extract contains flavonoid and folifenol can be used as a fungicidaland it has the lethal properties of couse gero, which is an antimicrobial compound, which is intended to test the potential grass-ethanol extract as liquid fertilizer s fusarium sp. The research method used in this study is experimental in the laboratory to know the potential ethanol extract in suppress the growth of the fusarium sp the study, which observations from reeds, has fungal and antibacterial compounds that can impede the growth oh the fusarium sp.

Abstract

This study aims to investigate the perceptions of mathematics education students related to the transition of online learning in pandemic era to blended learning in new normal era. The subjects of this study were 44 students of mathematics education department in academic year 2021/2022 in Mataram University. The research method implemented was descriptive qualitative. The data collection technique used questionnaires. The data in this study were analysed using statistics. Based on the findings, there were 50% of students selected full offline learning, 16% of students selected full online learning, and 34% of students selected blended learning. There were 61% of students considered that full online learning was sometimes effective, however 30% of them considered that it was ineffective, and 9% considered it effective. There were 42% of students stated that online learning was appropriate to be implemented in the learning materials related to education, 17% stated that it was appropriate to be implemented in the learning materials related to mathematics, 29% stated that there was no appropriate materials, and 12% stated that every material was suitable to implemennt online learning. It can be concluded that onlne learning is effective if it is combined with offline learning as a blended learning.

Abstract

The world population is predicted to continue increasing. Therefore, discovering another energy resource instead of fossil oil is essential. The geothermal resource can be used as alternative renewable energy. To identify the complex geothermal system in East Java as alternative renewable energy based on the gravity anomaly. This research investigated the Gunung Pandan geothermal system. The geophysical method was used which is the gravity method. The subsurface information was investigated using the Bouger Gravity Anomaly (ABL) method. The results show that the distribution of the gravitational anomaly in the Mount Pandan complex has a residual anomaly value of -3.2 mgal to 11.7 mgal. The residual anomalous contours represent positive clusters identified as intrusive rocks that heated the fluid around the fault and the suspected reservoir. thus, forming the manifestation of Banyukuning and Selogajah with the flow zone of each manifestation classified as an outflow zone for the manifestation of Banyukuning and upflow for the manifestation of Selogajah.
