Abstract

Penelitian ini dilakukan untuk mengidentifikasi daerah rawan longsor di Kecamatan Tombolopao, Kabupaten Gowa. Penelitian ini bertujuan untuk mengetahui nilai frekuensi dominan (fo), faktor amplifikasi (Ao), indeks kerawanan gempa (Kg) dan mengidentifikasi karakteristik lokasi longsor di daerah penelitian. Pengambilan data menggunakan seperangkat alat Seismograf Digital Portable tipe TDL-3035 pada 8 titik penelitian dengan spasi 15 m. Data sinyal mikrotremor tersebut kemudian diolah dengan metode HVSR pada software Geopsy sehingga diperoleh kurva H/V yang menyatakan nilai fo dan Ao. Nilai fo dan Ao kemudian digunakan untuk mendapatkan indeks kerentanan seismik (Kg). Hasil yang diperoleh dari sebaran nilai frekuensi dominan berkisar antara 0,685 – 5,745 Hz, nilai faktor amplifikasi antara 1,927- 3,193, nilai indeks kerawanan gempa antara 0,646- 9,029 dan karakteristik lokasi longsor berdasarkan nilai parameter indeks kerawanan gempa yang diperoleh dari persamaan empiris frekuensi dominan dan amplifikasi faktor berada pada titik pengukuran MT1, MT3 dan MT4.Kata kunci : Tanah longsor, mikrotremor, metode HVSR

Abstract

Virgin Coconut Oil is a pure coconut oil that can be obtained from the extract of fresh and old coconut meat. This study aimed to evaluate the performance of a biofermentor integrated with a fuzzy logic control system and IoT for VCO production. The research involved designing control rules to regulate temperature, testing the IoT system for real-time monitoring, and assessing the biofermentor's performance. The parameters observed were control system response, temperature, yield and moisture content.  Results showed that the fuzzy control system effectively maintained temperature stability, resulting in a higher yield (39.65%) and lower moisture content (0.08%) compared to conventional methods. In addition, the fuzzy control rules are able to regulate the power so that the temperature overshoot is quite small (1%), the settling time is relatively short (9 minutes), the temperature is stable, and the steady state error is 1.02% (with in tolerance limits).

Abstract

Understanding the concept of the demand function in economic mathematics is still a challenge for Madrasah Aliyah students due to the abstract and applicative nature of the material. This study aims to analyze the effectiveness of gamification using the Wordwall platform in improving students’ understanding of the demand function concept at MAS At-Taqwa Beru. This study uses a qualitative approach with a case study design involving 30 eleventh-grade students selected through purposive sampling. Data were collected through participatory observation, semi-structured interviews, and documentation, and analyzed thematically. The results showed an increase in active student participation from 55% to 80% during gamification learning and an increase in the average learning score from 62.3 to 78.5 (gain ±26%). Wordwall facilitated students’ understanding through interactive visualization and contextual questions, stimulated intrinsic motivation, and encouraged collaboration among students. These findings support social constructivism theory and Self-Determination Theory that interaction, autonomy, and instant feedback are important in building conceptual understanding. Theoretically, this research enriches the literature on gamification in economics learning at the Madrasah level, while practically recommending the integration of Wordwall as an effective alternative learning medium, supported by digital facilities and school policies so that its implementation can be carried out systematically and sustainably.
