Abstract

The lack of knowledge among students regarding animal species, particularly mammals, is a contributing factor to the loss of biodiversity. Therefore, it is essential to educate students about mammalia species through educational video. The aim of this research is to identify mammals in Ragunan Zoo for use as educational video content. The research methodology involved field exploration, followed by the creation of educational videos in the form of vlogs. Fifteen species were used as the subject of the learning videos about mammals. The species are classified into five orders: Artiodactyla (4 species), Carnivora (2 species), Primates (7 species), Proboscidea (1 species), and Rodentia (1 species). The learning videos are divided into two sections: non-primate group mammals https://youtu.be/jonAd08pNQ4  and primate group mammals https://youtu.be/iYNB9OpME4g?s. The firt video is 8 minutes and 20 seconds long and the second video is 9 minutes and 53 seconds long. These video can be use in the first step to introduce species diversity, especially mammals.

Abstract

Agriculture in Samosir Regency has great potential but still faces land degradation, dependence on chemical fertilizers, and low utilization of organic waste. The younger generation’s knowledge of sustainable agriculture remains limited, accompanied by negative perceptions of the sector, while practice-based studies at the high school level are rare. Therefore, this study aims to implement bioecoenzim and Lacuba fertilizer training and examine students’ knowledge and perceptions of these activities. The research was conducted at SMA Negeri 1 Sitiotio, involving 41 eleventh-grade students using a one-shot case study design. Data were collected through observation, documentation, questionnaires, and knowledge tests. The results showed that the training ran effectively, as evidenced by active student participation. Students’ perceptions were in the very positive category, with an average score of 87.97, while their knowledge was in the high category, with an average score of 89.76 (Above Average). Thus, bioecoenzim and Lacuba fertilizer training has proven to have the potential to enhance knowledge and foster positive perceptions among students toward sustainable agriculture. Therefore, expanding the application of bioecoenzim and Lacuba training in other schools is important as a practical environmental education tool to support sustainable agriculture.

Abstract

Umumnya bakteri probiotik yang digunakan dalam fermentasi adalah Lactobacillus spp. dan Bifidobacterium spp.  Secara khusus, bakteri probiotik mampu mengasamkan bahan baku dengan cepat dengan memproduksi asam laktat dan beberapa senyawa penting lainnya. Teknologi ini penting diperkenalkan pada peserta didik, khususnya siswa/i di SMA Dharma Suci Jakarta, kegiatan pengabdian kepada masyarakat bertujuan untuk mengedukasi dan melatih para siswa membuat produk fruit yoghurt yang dapat menumbuhkan kreativitas baru terhadap pembuatan produk probiotik berbahan dasar wortel dan buah naga. Kegiatan pembuatan produk fruit yoghurt sebelumnya belum pernah dilakukan di SMA Dharma Suci Jakarta, pada akhirnya kegiatan PKM ini menjadi penting untuk mengenalkan bioteknologi sederhana produksi fruit yoghurt melibatkan bakteri probiotik yang multifungsi bagi kesehatan. Metode pelaksanaan PKM ini meliputi tahapan persiapan, tahapan pelatihan dan tahapan evaluasi. Hasil kegiatan PKM ini menambah informasi baru bagi siswa terutama pengetahuan yang berhubungan dengan aktivitas probiotik, prebiotik dan sinbiotik pada produk fruit yoghurt. Hasil kuesioner sebelum mengikuti edukasi/sosialisasi persentase siswa yang memahami probiotik hanya 57,1%, setelah mengikuti sosialisasi meningkat hingga 100%. Pemahaman ini didukung hasil kuesioner mengenai pertanyaan proses yang terjadi selama produksi fruit yoghurt, hasilnya 71,4% respon siswa menjawab fermentasi. Hasil pembuatan fruit yoghurt setelah fermentasi 24 jam berhasil terbentuk produk, berdasarkan hasil survei menurut siswa fruit yoghurt didominasi rasa manis dan asam. Ciri ini mengindikasikan produk fruit yoghurt berbahan dasar buah naga dan wortel dikategorikan baik
