Abstract

Sowang (Xanthostemon novaeguineense Valet.) is an endemic plant of Papua whose population is currently experiencing very high pressure due to overexploitation, and the morphological characteristics of Sowang are very difficult to develop generatively, it is necessary to make efforts to reproduce vegetatively. Vegetative propagation is an alternative that needs to be done, one of which is by cuttings. Research on the effect of giving growtone on Sowang's growth has been carried out from March to July 2020, at the Green House Laboratory of the Department of Biology, FMIPA, Cenderawasih University, Jayapura, Papua. This study aims to determine the effect of giving growtone with different doses, types of cuttings, and the interaction of these two factors on the growth of Sowang cuttings. This study used an experimental method with a factorial Completely Randomized Design (CRD) with two factors and three replications. Factor 1, growtone (D0: control, D1: 50 ppm, D2: 100 ppm, and D3: 150 ppm), and factor 2, the type of cuttings Sowang (S1: shoot cuttings and S2: stem cuttings). The results showed that different doses of growtone and the type of cuttings had a significant effect on the growth of Sowang cuttings. The dose of growtone 150 ppm and the type of stem cuttings gave the best results in increasing the growth of Sowang shoot cuttings.

Abstract

Science process skills include cognitive and psychomotor skills that can contribute to helping students learn facts, concepts, principles, or theories, so that students can effectively study science. This research was conducted to examine whether there is an effect of implementing the concept map method in guided inquiry learning on students' science process skills. The study was conducted with an Intact Group Comparison design. The research subjects were junior high school students in Mataram City. The research took place in the even semester of the 2020/2021 academic year. Purposive sampling technique was applied to obtain a sample of 91 individual students from two junior high schools. The results showed that, students who implemented concept map preparation during guided inquiry learning had a higher science process skill score than students who applied guided inquiry learning, but did not make concept maps and conventional class students. The conclusions of this study indicate that the preparation of concept maps in guided inquiry learning has a significant effect on students' science process skills. Based on these conclusions, it is recommended that educators try to apply guided inquiry learning, accompanied by assignments to make concept maps.

Abstract

Infectious diseases can be caused by one of four different organisms, namely: bacteria, fungi, viruses, and parasites. This study aims to determine the ability and concentration of the best ethanol extract of red fruit seeds (Pandanus conoideus Lamk.) In inhibiting the growth of Escherichia coli and Staphylococcus aureus infectious bacteria. This research is an experimental study using a completely randomized design (CRD). The stages of work carried out consisted of: sample preparation, sample extraction, solution concentration preparation, and inhibition testing. The research work procedure began with the process of preparing a sample of red fruit seeds into powder. The maceration method was used for extraction using 96% ethanol with a ratio of 1: 3. The concentration of the extract was made by mixing the macerated extract with aquadest solvent. The concentration variations made were: 0.31%, 0.63%, 1.25%, and 2.50%. Inhibition testing against bacteria was carried out using the Kirby-Bauer method. The data obtained were analyzed using Analysis of Variance (ANOVA). The results showed that the ethanol extract of red fruit seeds had bioactive compounds that could inhibit the growth of Escherichia coli and Staphylococcus aureus bacteria. The bioactive compounds consist of phenols, flavonoids, steroids, terpenoids, alkaloids, and tannins. The average diameter (mm) of the inhibition zone of Staphylococcus aureus bacteria was greater than the average diameter (mm) of the inhibition zone in Escherichia coli bacteria due to differences in the structure of their cell walls. The increase in the concentration of the solution is directly proportional to the diameter of the formed zone of inhibition. The higher the concentration given, the larger the diameter of the inhibition zone is seen. Duncan test analysis showed that 2.5% ethanol extract concentration was the best concentration in inhibiting bacterial growth.

Abstract

Fusarium oxysporum Schlecht. f.sp. cepae (Hanz.) Synd. et Hans. is a fungus that causes Fusarium wilt in shallots, which causes damage to tubers and reduces yields by more than 50%. This disease is difficult to control, because it can form spores that can survive in the soil for a long time, and are saprophytic on the remains of other plants. This study was conducted to determine the effect of the application of 5 kinds of Actinomycetes isolates (SW13, SW5, BYM1, BYM4, and SIO 5), with 3 kinds of concentrations (5 ml, 10 ml, and 15 ml/plant) on the Mentes variety shallots. Fusarium oxysporum. The results showed that the application of the isolate code SIO5 to the Mentes variety of shallots gave the best effect in suppressing the attack of Fusarium oxysporum by 52.2%. In addition, the suspension of SIO5 isolate also had a positive effect on plant height of 41.5 cm, number of tillers of 8.89, and tuber weight of 42.84 grams. While the type of concentration did not have a good effect on the incidence of disease, plant height, and the number of tillers and tuber weight.

Abstract

Zebra fish (Danio rerio) is a laboratory animal that can be used for a wide field of research, testing, and education. Laboratories that wish to use Zebra Fish must have their own Zebra Fish rearing facility. The next step is to breed parental Zebra Fish from external sources until filial 1 (F1) is obtained in the facility which is then used later. This research is descriptive experimental, which describes the practical experience of providing maintenance, breeding, and rearing facilities for embryos and larvae. Quarantine specific facilities, number of tanks, water pH conditions, breeding methods, facility cleaning routines, and special larval feeds need to be considered for the success of early stage rearing facilities. This study showed that the embryo safety rate ranged from 38.2% to 88.9%. Meanwhile, for larvae up to the age of 21 dpf it ranged from 1.5%-9.1%, which indicated that the rearing conditions were still suboptimal, especially larval rearing. Facility procurement and maintenance costs are divided into mandatory and optional costs depending on the needs, location and time of the maintenance facility. Laboratories can independently design maintenance facilities that are effective to meet research needs and are cost efficient.
