Spark plugs have various types and specifications that can improve motorcycle performance. The purpose of this study was to determine the ratio of torque, power, and fuel consumption in a two-stroke gasoline engine produced from standard, platinum, and iridium spark plugs. The method used in this research is to use the one-way variance test method or One-way ANOVA. This test was carried out using a Yamaha F1ZR motorcycle which was carried out using a dyno test tool. The test results for this platinum spark plug have the highest torque reaching 14.78 ft-lbs at 7,500 rpm engine speed, while for standard spark plugs obtained 10.14 ft-lbs. at 7500 rpm engine speed and iridium spark plugs get 9.53 ft-lbs at 7500 rpm engine speed. The highest power is obtained on platinum spark plugs reaching 14.78 hp at 7500 rpm engine speed, while for standard spark plugs 14.47 hp at 7500 rpm engine speed and for iridium spark plug 13.62 hp at 7500 rpm engine speed. The lowest fuel consumption is produced on iridium spark plugs which reaches 0.545 kg/hour at 5000 rpm engine speed, while the highest fuel consumption on platinum spark plugs reaches 0.700 kg/hour at 9000 rpm engine speed.

This study aims to determine the effectiveness of kecombrang flower extract (Etlingera elatior jack R.M.sm) on the death of Culex quenquefasciatus Say larvae. Experimental animals used were Culex quenquefasciatus Say larvae, amounting to 625 tails. The design used was a randomized complete design with 5 treatments and 5 replications. The five treatments consisted of two test groups, namely the treatment group consisting of concentrations of 5%, 10%, 15%, and the control group consisting of positive control namely abate and negative control namely aquades. Observation of mosquito larvae death was done every 2 hours for 12 hours. The data obtained were analyzed using the one-way ANOVA test and continued with the Duncan test. Based on the results of the one way ANOVA calculation the value of sig.0.00 <0.05 means that there are significant differences between treatments. Duncan test results on the treatment of 10% and 15% kecombrang flower extract have the ability as a larvicide high and equal to positive control (abate). Based on the results of the study it was concluded that the extract of kecombrang flower (Etlingera elatior jack R.M.sm) had the ability to larvae against the Culex quenquefasciatus Say mosquito.

Scientific Literacy (SL) is an important competency to deal with and keep up with the increasingly sophisticated technological developments. However, information about the SL of prospective gifted young scientists over 15 years old has not been widely revealed holistically. Therefore, this survey research aimed to investigate the SL performance of prospective gifted young scientists holistically and compare the SL performance based on the grade level. A total of 278 students from a public senior high school in Jombang Regency, East Java Province, Indonesia, participated in this research. They were asked to take the SL test with 18 essential question items. As a result, the participants still showed low SL performance (total success rate = 40). The one-way ANOVA test results indicated no significant difference in the participants' SL performance based on the grade level. Therefore, three recommendations were provided: teachers should use various learning models, SL should be an explicit focus in science and non-science classrooms, and schools need to be equipped with supporting facilities to accommodate student readiness to practice SL.

The aim of this study is to develop the one-dimensional model of a four-cylinder, four-stroke, multi-point injection system SI engine and a direct injection system SI engine for predicting the effect of various fuel types on engine performances, specific fuel consumption, and emissions. Commercial software AVL BOOST was used to examine the engine characteristics for different blends of methanol and gasoline (by volume: 5% methanol [M5], 10% methanol [M10], 20% methanol [M20], 30% methanol [M30], and 50% methanol [M50]). The methanol-gasoline fuel blend results were compared to those of net gasoline fuel. The obtained results show that when methanol-gasoline fuel blends were used, engine performance such as power and torque increases and the brake-specific fuel consumption increases with increasing methanol percentage in the blended fuel.

Prevention by utilizing medicinal plants can be used as an alternative treatment. This study aims to identify active antimicrobial substances and test the antimicrobial potential of traditional Balinese spices, namely Basa Selem, Basa Gede, Basa Wangen, Basa Bawang Jahe, and Basa Rajang against Salmonella sp bacteria in vitro. The True-experimental method with Posttest only-control design was used in this study, by intervening in the treatment group as well as the presence of positive and negative controls. The maceration method with 96% EtOH solvent was used to extract active substances and identify the levels of antimicrobial active substances. The TLC Spectrophotodensitometer instrument and the diffusion method (discs) were used to test antimicrobial potential. Data analysis was performed using the one-way ANOVA test. All five samples showed flavonoids, alkaloids, tannins, and phenols in qualitative tests. Based on quantitative test results of five samples, the highest compound content obtained in Basa Wangen (6.66 mg/ml of tannins), Basa Gede  (3.74 mg/ml of flavonoids), Basa Bawang Jahe (2.49 mg/ml of tannins), Basa Selem (2.87 mg/ml of tannin), and Basa Rajang (6.96 mg/ml of flavonoids). There are differences in the antimicrobial potential of various types of traditional Balinese spices against the growth of Salmonella sp in vitro (sig = 0.037). The traditional Balinese spices have the antimicrobial potential of the intermediate category with a range of inhibition (16-20 mm) based on the NCCLS standard.

Depression is a mood disorder that is characterized by profound and sustained sadness and sadness until the loss of life passion. Lemongrass which contains eugenol is thought to have the potential as an antidepressant that works by inhibiting the Mono Amine Oxidase enzyme. This study aims to determine the effectiveness of antidepressant citronella extract (Cymbopogon nardus (L.) Rendle) on male white mice. This study used 5 treatment groups namely CMC Na 0.5%, amitriptilyn, lemongrass extract dose 1.5 mg/kgBB, 15 mg/kgBB and 150 mg/kgBB. Antidepressant testing was determined based on immobility time using the forsed swim test method. Data analysis using statistics was tested for normality and continued with the One Way Anova method with a 95% confidence level. The results showed that the most effective treatment group as an antidepressant was amitriptilyn followed by lemongrass extract dose 150 mg/kgBB. The conclusion of this study is that lemongrass extract dose 150 mg/kgBB has the effectiveness as an antidepressant but is no more effective than the comparison of amitrip

Good acceleration and performance are influenced by the degree of flexibility of the clutch springs. The objective that underlies the implementation of this study is to determine the effect of replacing the clutch spring with different length variations. In this study, the data taken is the torque, power and fuel consumption of each type of clutch spring. In this test, two types of clutch springs were used, namely the standard clutch spring and the TDR type coupling spring which were varied in length (38.31mm), (40.93mm) with the addition of 2mm (42.93mm), (40.31mm) rings. also cutting thread 2mm (38.93mm), (36.31mm). Tests were carried out using a dynotest tool with an engine speed of 4000 rpm to 9000 rpm transmission position six. In the TDR clutch spring (42.93mm) there is an increase in torque of 7.42% with a torque yield of 16.20 Nm at 6000 rpm and an increase in power of 6.61% with a power yield of 14.5 HP at 7000 rpm. For fuel consumption TDR coupling spring at ideal rotation (low-medium), an increase of 9.68%. The decrease in fuel consumption only occurred at the top / high speed of 6.32%. For the test results pertalite ethanol fuel, there is a decrease in fuel consumption compared to pertalite fuel for all RPM variables

A variable speed engine generator set for an isolated power system is investigated to reduce fuel consumption and emission than conventional fixed speed engine generator. An inverter incorporated with the variable speed gasoline engine generator set can improve dynamic characteristics under a sudden load change, and power quality, fuel consumption, and emission of pollutants can be improved remarkably. The superiority of a fuzzy neural network control to the engine speed and a digital PID controller to the inverter is verified by the experimental results.
