This research aims to find out and analyze learning experiences in using online learning media during the COVID 19 pandemic of the second-year undergraduate students of English Education study program at Tadulako University Palu. The researcher applied qualitative case study research methodology. It investigates intensively about an individual, group, or other units to find a general understanding of the subjects. The subject was selected using snowball sampling techniques in which the four students were chosen intentionally for research participants from 236 students. The researcher initially contacted her quittance then introduces her to the first interviewee, for good measure the interviewee introduce her to the next ones.  Data were collected through in-depth interviews and documentary data. In this research, the researcher found that the students from case two in Menui Island who are in their hometown during the online learning period faced a number of difficulties in their learning experiences. Their learning experiences include learning motivation and learning obstacles. The results have shown that the first is unavailability and unsustainability of internet connection, the second is the accessibility of the teaching media, and the last is the compatibility of facilities to access the media. The result of the current study suggests that accessibility of the internet connection is still the major factor influencing the success of online learning and concludes that the students have less motivation to study and face a lot of obstacles in the search for internet availability. Also implies that online learning media is considered an unsuccessful method of learning during COVID-19 era for students in the remote area particularly in Menui island. As a preventive action, the government should install more Telkom towers in remote areas like Menui in order for the students to achieve the national learning objective.

The objective of this research is to find the effect of problem-based learning to the speaking ability of the tenth grade students at SMK Muhammadiyah 1 Palu. This research employed experimental research of quasi-experimental design. The samples were the students of X Farmasi as the experimental group and the students of X TKJ A  as the control group. They were selected using convenience sampling technique. The data were collected through pretest and posttest analyzed by using t-test formula to compare the mean score of the experimental and control groups. The result of the data analysis shows that t-table (1.968) higher than t-value (0.96), so the hypothesis is rejected. It means problem-based learning has no effect significantly to the students speaking ability. That  caused by several factors such as situation, teaching implementation, and students participation.

The objectives of this research are to investigate and analyze the students’ perception on the implementation of Discovery Learning Method in reading comprehension and the challenges that the students face on the implementation of Discovery Learning Method in reading comprehension. In addition, this research was conducted through qualitative approach. The data of this research were taken from 30 students at SMK Negeri 1 Terpadu Sindue. In collecting the data of this research, the researcher used questionnaire and interview to the students. Questionnaire was used as the main instrument of this research and interview was used to support the results of the questionnaire. Questionnaire was in the form of statement and it included four degrees of answer option. Then, after analyzing the data obtained, it was concluded that Discovery Learning Method is effective to be implemented. It was perceived by the students that the method gives them insights of learning materials, allows them to explore the reading material, makes them more active in class, improves their analytical thinking, and gives them an opportunity to discover information collected earlier with friends. However, the students faced some challenges during the implementation of this method. The challenges that the students face on the implementation of Discovery Learning Method in reading comprehension are: the difficulty in understanding reading text which is too long, unclear instruction from the teacher, lack of vocabulary, and the learning situation (current teaching and learning process during the pandemic).

Perubahan kondisi lingkungan (suhu udara, kelembapan dan curah hujan) merupakan hal penting yang harus di perhatikan dalam perkembang biakan nyamuk Anopheles. Kepadatan nyamuk Anopheles perlu diketahui dan harus diperhatikan untuk mencegah dan memotong penularan penyakit malaria.Tujuan dari penelitian ini adalah untuk mengetahui hubungan kondisi lingkungan dengan kepadatan nyamuk Anopheles. Adapun jenis penelitian ini yaitu Studi Kepustakaan (library research). Penelitian dilakukan dengan teknik pengumpulan data (literature) sehingga dapat diketahui hubungan kondisi lingkungan dengan kepadatan nyamuk Anopheles.Dari hasil analisa beberapa literatur yang telah didapat maka suhu udara sangat mempengaruhi panjang pendeknya siklus sporogoni atau masa inkubasi ekstrinsik maupun instriksik. Tinggi maupun rendahnya kelembapan akan mempengaruhi proses perkembangbiakan nyamuk Anopheles. Dan Hujan dapat menciptakan habitat untuk vektor tetapi juga dapat menyebabkan larva hanyut dan mati.Kesimpulan dalam penelitian ini adalah ada hubungan kondisi lingkungan dengan kepadatan nyamuk Anopheles. Saran kepada masyarakat agar dapat memperhatikan kondisi lingkungan sekitar sehingga dapat mencegah terjadinya kepadatan nyamuk Anopheles dan terhindar dari penularan penyakit malaria.Kata kunci : Kondisi Lingkungan, Kepadatan Nyamuk, Anopheles.
