Abstract

The coastal of Kota Bani in Bengkulu is directly connected to the Indian Ocean, which has strong waves and currents that have the potential for rip currents. Recently, Kota Bani coast has experienced rapid shoreline changes caused by abrasion. Therefore, the purpose of this study is to identify rip current generating parameters, microzonation mapping of shoreline changes and its relationship with the potential zone of rip current occurrence at Kota Bani Coast, Bengkulu. The methods used in this study were in situ measurement of rip current generating parameters and identification of rip current using drone photos and USGS data to see shoreline changes. Analysis was done descriptively and quantitatively. Based on the research results, the type of breaking wave found at Kota Bani Coast is the plunging type with an irribaren value of 0.3 - 2.3. The potential for rip current occurs more in the west season than in the first transitional season. Rip current speeds of 3 m/s in the west season and 2.2 m/s in the first transitional season. Based on photo data of the coastline from the USGS for 10 years, the abrasion zone experienced a total coastline setback of 149.9 meters and in the non-abrasion zone experienced a total coastline increase (sedimentation) of 113.3 meters, with an average per year.  Pantai Kota Bani Bengkulu Utara berhubungan langsung dengan Samudera Hindia yang memiliki gelombang dan arus kuat yang memiliki potensi kemunculan rip current. Akhir-akhir ini Pantai kota Bani mengalami perubahan garis pantai yang sangat cepat yang disebabkan abrasi. Oleh sebab itu tujuan penelitian ini adalah mengidentifikasi parameter pembangkit rip current, pemetaan microzonasi perubahan garis pantai dan  hubungannya dengan zona potensi rip current di Pantai Kota Bani Bengkulu. Metode yang digunakan dalam penelitian ini adalah pengukuran in situ parameter pembangkit rip current dan identifikasi rip current menggunakan foto drone serta data USGS utuk melihat perubahan garis pantai. Analisis dilakukan secara diskriptif dan kuantitatif. Berdasarkan hasil penelitian diperoleh tipe gelombang pecah yang terdapat di Pantai Kota Bani yaitu tipe plunging dengan nilai irribaren 0,3 - 2,3. Potensi kemunculan rip current lebih banyak terjadi pada musim barat dibandingkan musim peralihan I. Kecepatan rip current pada musim barat 3 m/s dan pada musim peralihan I 2,2 m/s. Berdasarkan data foto garis pantai dari USGS selama 10 tahun zona terabrasi terjadi total kemunduran garis pantai 149,9 meter dan pada zona tidak terabrasi mengalami total kemajuan garis pantai (sedimentasi) 113,3 meter, dengan rata-rata perubahan garis pantai per tahun 3,7 m. Zona abrasi dan tidak terabrasi sama-sama berpotensi munculnya rip current, akan tetapi kemunculan rip current lebih banyak pada zona terabrasi, hasil yang didapat menunjukkan bahwa rip current menjadi salah satu faktor mempercepat terjadinya abrasi di Pantai Kota Bani.

Abstract

Abstract Background: Bengkulu's tropical climate is very suitable for Ae. aegypti and Ae. albopictus mosquito breeding. Temperature, humidity and rainfall affect mosquito breeding and dengue virus proliferation in mosquitoes, which in turn had an effect on the dengue infections. Dengue prevention strategy currently focuses on vector control with the Larvae Free Rate (LFR) parameter. This study aimed to determine environmental factors affecting the LFR in 2022 in Bengkulu City, Indonesia.Methods: This research used a cross-sectional study design with time series analysis. Time series was used to analyze and interpret sequential data points collected over  the interval of time. Secondary data about LFR was obtained from the Bengkulu City Health Service, and climate variables from the Climatology Station of the Bengkulu Meteorology, Climatology, and Geophysics Agency. Data analysis was conducted through simple linear regressions.Results: The average of LFR in Bengkulu City in 2022 was 78.13% (below the national target), with the highest in December (87.85%) and the lowest in May (68.53%). The average temperature, humidity, and rainfall were 26.88°C (moderate), 83.5% (moderate), and 328.96% (high), respectively. The simple linear regression analysis showed that the effect of temperature, humidity, and rainfall was significant to LFR with the respective p-values of 0.010; 0.612, and 0.173).Conclusion: Temperature influenced the LFR by 58,5% but humidity and rainfall have no effect on LFR of Aedes spp. in Bengkulu City in 2022. High temperatures will increase the risk of transmission of dengue virus infection by 3-5%.

Abstract

Many studies showed that teachers' knowledge of instructional strategies is related to another component of pedagogical content knowledge. However, studies on teachers' reasons for choosing their instructional strategies still need to be reported. Three mathematics teachers were investigated using a case study research design. The data were gathered through two semi-structured interviews, pre- and post-observation, as well as observations. Pre-observation interviews explored teacher's knowledge of instructional strategies (KIS) based on their experiences or knowledge. Meanwhile, the post-interview investigated teachers' reasons for choosing instructional strategies based on the observations. Five to ten lesson hours were allocated to observe the teachers' activities in learning on the topic of linear equations and inequalities of one variable. A cross-case analysis was performed to compare the teachers' KIS and their reasons for choosing instructional strategies in teaching practice. The findings showed that lecturing, questioning, and solving problems are the most dominant strategies used by teachers. Only one teacher used group discussion in her teaching activities. The finding also indicates that the knowledge of the student's understanding, curriculum, beliefs, and teaching context are factors that influence teachers in choosing instructional strategies. In addition, the reasons for choosing those strategies are varied.

Abstract

The observation of smoke because of land and forest fires in some regions in Indonesia mostly use the composite image visually. This study aims to develop the detection model of forest and land fire smoke using a digital analysis, which will be faster in supporting spatial information on emergency response in monitoring forest and land fire smoke. The method used is multi-threshold method and compare it with the existing model that is by modification of method Li et al. (2015). The data used is Suomi NPP-VIIRS satellite imagery. The results concluded that the VIIRS image can be used to detect the smoke and smoke distribution of forest fire and digital smoke. The multi-threshold model uses reflectance data obtained from the M4 visible channel, and the brightness temperature data obtained from the LWIR VIIRS M14 channel, with an average accuracy of 82.2% with a Commision error of 9.8% and an Ommision error of 10%. While the model of modification Li is based only on reflectance of visible-channel data i.e. channel M1, M2, M3, and SWIR VIIRS M11 channel, which has an average accuracy of 72.3% with a Commision error of 0.3% and an Ommision error of 27.4%. The multi-threshold model is a model that has the potential to be applied to detect forest and land fire smoke.
