Enhancing EFL Students’ Reading Comprehension through the Use of Schema Activation Techniques
Full text linkThis study investigates the effect of the Schema Activation Strategy on EFL students’ reading comprehension, particularly in analyzing and interpreting narrative texts. A quasi-experimental design was employed involving 68 eleventh-grade students divided into an experimental group and a control group. Over four weeks, the experimental group received instruction using schema-based activities such as K-W-L charts, pre-teaching vocabulary, visual aids, and case-based reading, while the control group was taught using conventional methods. Pre-tests and post-tests were administered to both groups, and the data were analyzed using descriptive statistics and inferential analysis (paired and independent samples t-tests). The results showed that both groups improved their reading comprehension performance; however, the experimental group demonstrated a significantly higher mean gain (9.94 points) compared to the control group (8.83 points). Furthermore, an independent t-test revealed a statistically significant difference in post-test scores between the groups (t = 2.439, p = 0.017), favoring the experimental group. These findings confirm that schema activation strategies, which engage learners\u27 prior knowledge, effectively enhance inferential understanding, critical thinking, and textual interpretation in EFL contexts. The study suggests incorporating schema-based reading instruction into the EFL curriculum to foster deeper comprehension and metacognitive skills

Studi Perbandingan Viskositas dan Kelayakan Beberapa Merek Oli SAE 10W-40 Menggunakan Prototipe Alat Falling Ball Viscometer
Full text linkThe determination of oil quality in conventional engine vehicles is carried out by measuring the coefficient of viscosity and kinematic viscosity. Good kinematic viscosity should not decrease by more than 50% from its initial value. This research uses the Falling Ball Viscometer (FBV) method to measure the viscosity of five brands of SAE 10W-40 oil: Enduro 4T Racing, Shell Advance 4T, Castrol Power 1 4T, Fastron Techno, and Mobil Supermoto at temperatures of 40°C and 100°C. Testing was performed on new oil and after traveling 3000 km. The results showed a decrease in kinematic viscosity by 21%-42% at 40°C and 24%-30% at 100°C. The device uses a reed switch magnet sensor and Arduino UNO microcontroller to process and display data on an LCD. The comparison between the device and manual measurement showed a difference of 0.12-0.7 at 40°C and 0.06-2.16 at 100°C, with an average correction of 0.84-1.5 at 40°C and 0.23-0.40 at 100°. This research is crucial for vehicle users as it provides more accurate information regarding the degradation of oil quality after usage, helping users determine the optimal time for oil replacement to maintain fuel efficiency, performance, and engine durability. For the lubricant industry, the findings of this research can be utilized to improve oil formulations that are more resistant to viscosity reduction due to temperature and mileage, thereby meeting higher quality standards in the market.Penentuan kelayakan oli kendaraan bermesin konvensional dilakukan dengan mengukur koefisien viskositas dan viskositas kinematik.

The Influence of Land Area on Rice Farmers\u27 Income in SP9, Jabamaru Village, Tanah Miring District, Merauke Regency
Full text linkThis study aims to determine the effect of land size on the income of rice farmers in SP9 Jabamaru Village, Tanah Miring District, Merauke Regency. The research is motivated by the significant role of agriculture in Indonesia\u27s economy, especially in areas where most residents are farmers. Land size is one of the critical factors influencing the success of farming activities, as it affects production capacity and directly impacts farmers\u27 income. This quantitative research uses a survey method involving 53 rice farmers as a sample from a total population of 214 farmers. Data collection techniques include observation, interviews, and questionnaires. The data were analyzed using simple linear regression with IBM SPSS version 25. The results show that land size has a positive and significant effect on farmers\u27 income. The regression coefficient of 9,585,807.223 indicates that each additional hectare of land significantly increases income. A significance value of 0.000 (smaller than 0.05) and a t-statistic of 16.262 (greater than t-table 1.675) support this result. Therefore, the hypothesis that land size affects farmers\u27 income is accepted. The study recommends that farmers improve land management efficiency and optimize land use to enhance their income levels
Calculation of Tsunami Wave Run-Up and Velocity in Sidangoli Bay, West Halmahera
Full text linkDue to its complex and unique geological tectonic system, North Maluku is prone to tsunami hazards. The cause of the tsunami is likely to be a megathrust earthquake. Although there are few casualties and only localized tsunamis, they significantly affect the region\u27s stability. One of the areas recorded by the Indonesian paleo tsunami database on 28 June 1859, when a strong earthquake occurred in the Maluku Sea with a magnitude of 7, was Sidangoli Bay, with a tsunami wave run-up of 10 meters. Therefore, it is necessary to calculate the run-up and velocity of tsunami waves to mitigate tsunami disasters. The calculation method uses mathematical equations with a Python program combining various parameters. The data processing resulted in tsunami modelling showing the run-up value and tsunami wave speed in Sidangoli Bay, South Jailolo. The tsunami wave propagation speed reached 80 meters/second, and the tsunami wave height reached 28 meters. The run-up and velocity of tsunami waves in Sidangoli Bay are significant and may destroy anything in their path
Effect Of NAA And Kinetin Administration On Callus Induction In Vanilla Plant Stem Explants (Vanilla planifolia Andrews)
Full text linkVanilla (Vanilla planifolia Andrews) is a plantation plant that is used for its fruit. Indonesia is one of the countries that exports vanilla and has climate factors that support increasing vanilla production to meet global demand, One of the efforts that can be made in vanilla propagation is through plant tissue culture. This research aims to induce calluses. This study used a Random Design using stem explants and several different hormone concentrations, namely: 0.0 ppm NAA and 0.0 ppm Kinetin, 1.0 ppm NAA and 0.5 ppm Kinetin, 1.0 ppm NAA and 1.0 ppm Kinetin, 2.0 ppm NAA and 0.5 ppm Kinetin, 2.0 ppm NAA and 1.0 ppm Kinetin, 2.0 ppm NAA and 2.0 ppm Kinetin. There was an effect on the administration of NAA and Kinetin on callus induction in the explants of the vanilla plant (Vanilla planifolia Andrews). It is based on the Anova one-way Hypothesis Test with a significance value of 0.000 (Asymp. Sig <0.05) then Ho was rejected and H1 was accepted. The optimal concentration to induce callus in stem explants is the administration of 1.0 ppm NAA + 0.5 ppm Kinetin with an average callus growth rate of 7 HST and a 100% callus growth percentage of explants.
Keywords: Vanilla, induction, callus, tissue culture, hormonesMangrove ecosystems play an important role in the life cycle of various types of fish, shrimp and crabs. Because the mangrove environment provides protection and nutrients in the form of organic matter that is included in the food chain. Some of the fauna that are commonly found in the Indonesian mangrove ecosystem area are fauna from the gastropod, crustacean, bivalve, polychaeta, and pisces classes. One of the biota that can be used as biological parameters in determining the conditions of a body of water is macrozoobentos. As organisms living in waters, macrozoobentos are very sensitive to changes in the quality of the water in which they live so that it will affect their composition and abundance. This research method is quantitative descriptive research by taking data in a survey. It uses a 1x1m measuring plot 100m long perpendicular to the coastline. The measurement method used to determine the environmental conditions of mangroves is the transect line method and sample plots (Tran-sect Line Plot). The diversity index value at research locations I and II is in the medium category, while in location III it is in the high category. Of the three stations, the uniformity index is stable close to 1. Result The dominance index value is that there is no type that dominates a body of water, this means that all individuals at the observation station have the same opportunity and maximally make the most of the resources in those waters. The pH results of water at station II and station III did not differ significantly, while at station I it differed significantly when compared to the results at stations II and III. The salinity results at station III differ significantly from station I and II because the location of the mangrove is the location of a sea estuary that makes the salt content of brackish water mixed with fresh water
