The low level of science process skills is caused by several factors, one of which is: when learning activities are carried out online, more lecture methods are used than other methods. Based on the problem analysis, a mini research project-based learning tool was developed with the help of the facebook application on the theme of natural disasters to foster students' science process skills. This study aims to determine the validity of learning tools and determine whether there is growth in science process skills after being taught using the learning tools that have been developed. The research model used is Research and Development or Thiagarajan's development research model which consists of four stages of development, namely the Define, Design, Develop and Disseminate stages. The instruments used to collect data are interview instruments, validation questionnaire sheets, pre-test and post-test sheets. The results showed that the overall value of learning device experts and media experts received an average value of 89.3% which fell into the ‘very valid’ category. And the results of the hypothesis test obtained a Sig. (2-tailed) value of 0.000 and a result value of 11.222. Sig.(2-tailed) value of 0.000 <0.05 and the result value (11.222) > t table (2.045) indicates that there is an effect of learning devices on students' KPS. It can be concluded that the learning device is suitable for use and can foster students' science process skills. date: 2025 type: Thesis type: NonPeerReviewed format: text language: en identifier: https://eprints.untirta.ac.id/47895/1/Muhammad%20Agis%20Madhani_2281190059_CP.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47895/2/Muhammad%20Agis%20Madhani_2281190059_Fulltext.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47895/3/Muhammad%20Agis%20Madhani_2281190059_01.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47895/4/Muhammad%20Agis%20Madhani_2281190059_02.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47895/5/Muhammad%20Agis%20Madhani_2281190059_03.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47895/6/Muhammad%20Agis%20Madhani_2281190059_04.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47895/7/Muhammad%20Agis%20Madhani_2281190059_05.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47895/8/Muhammad%20Agis%20Madhani_2281190059_Ref.pdf format: text language: en identifier: https://eprints.untirta.ac.id/47895/9/Muhammad%20Agis%20Madhani_2281190059_Lamp.pdf identifier: AGIS MADHANI, MUHAMMAD (2025) PENGEMBANGAN PERANGKAT PEMBELAJARAN BERBASIS PROYEK MINI RISET BERBANTUAN APLIKASI FACEBOOK TEMA BENCANA ALAM UNTUK MENUMBUHKAN KETERAMPILAN PROSES SAINS (KPS).
