Abstract

The overuse of chemical fertilizers can have detrimental effects on soil quality. It is important for farmers to find sustainable alternatives. One possible solution being explored is the use of liquid maggot derived from organic sources. This study aimed to determine the most suitable composition that fulfills plant needs and follows established guidelines. The research approach employed a qualitative descriptive method to assess the impacts of three treatments using different types of organic matter: fruit waste, restaurant waste, and palm oil cake. Phosphorus and potassium concentrations were determined through MP-AES analysis while nitrogen content was measured using the Kjeldahl method. The findings revealed that only the treatments involving fruit waste and restaurant waste met the recommended potassium levels. However, these treatments fell short of meeting requirements for other essential nutrients. As a result, additional research is needed to assess nutrient concentrations in different organic substances.

Abstract

One of the main causes of problems in the Final Processing Site (TPA) of Lampung Province is the increasing pile of plastic waste produced by human activities. This can be a source of microplastic pollution and is dangerous if it settles in the body of organisms. Fungi can be an alternative to help the natural biodegradation process reduce microplastic pollution in the soil ecosystem. This study aims to identify and characterize fungal isolates that can degrade microplastics in the Final Processing Site (TPA) of Lampung Province. The sampling method was purposive sampling. The growing colonies were identified by observing the clear zone, then characterized morphologically. Data analysis using qualitative descriptive methods and measuring the clear zone index. This study successfully identified 13 fungal isolates that showed clear zone areas. Four isolates (Ba1.2, Ba2.5, Bu3.4, Ka2.3) could degrade three types of microplastics. The highest clear zone: Bu3.4 for PET (2,00 mm), Ka2.4 for PE (1,50 mm), and Ba2.3 and Ba2.5 for PP (1,25 mm). Identification and morphological characterization showed 8 isolates belonging to the genus Aspergillus, 3 isolates of Penicillium, 1 isolate of Fusarium, and 1 isolate of Sclerotium. Degradation occurs through hyphal adhesion and secretion of polymer-degrading enzymes.

Abstract

Pendidikan merupakan suatu modal penting bagi seseorang untuk menjalani kehidupannya. Penelitian pada kali ini juga dilatar belakangi oleh rendahnya rataan hasil belajar kognitif peserta didik. Hasil belajar yang rendah tersebut disebabkan karena tingkat pemahaman konsep yang kurang sehingga nilai yang diperoleh peserta didik banyak yang tidak memuaskan. Selain kemampuan untuk memahami, hubungan kerjasama dan tingkat kecerdasan antar peserta didik yang masih kurang tersebut bisa membuat proses pembelajaran menjadi kurang kondusif. Kecerdasan ini belum dimunculkan saat proses pembelajaran, karena salah satu contoh kecerdasan antar pribadi adalah kemampuan untuk memahami dan bekerjasama satu sama lain. Salah satu strategi yang bisa digunakan adalah dengan menerapkan strategi joyfull learning atau pembelajaran yang menyenangkan menggunakan mind map.Penelitian ini bertujuan untuk mengetahui apakah ada pengaruh strategi joyfull learning dengan teknik mind map terhadap hasil belajar kognitif khususnya materi sistem ekskresi di SMA Negeri 6 Bandar Lampung. Jenis penelitian quasy eksperimental dengan jenis nonequivalent control group design. Populasi dalam penelitian ini adalah peserta didik kelas XI SMA Negeri 6 Bandar Lampung dengan sampel penelitian terdiri dari 2 kelas yang diperoleh menggunakan tehnik Cluster Random Sampling. Kelas eksperimen XI IPA 1 dan kelas kontrol XI IPA 3. Teknik pengumpulan data observasi, tes (pretest dan posttest) dan dokumentasi. Hasil penelitian dan pembahasan perhitungan uji t independent dengan sampel tidak berkorelasi diperoleh bahwa thitung =3,625 dan ttabel =2,001. Hal ini berarti bahwa thitung lebih besar dari ttabel sehingga dapat disimpulkan bahwa terdapat pengaruh strategi joyfull learning dengan teknik mind map terhadap hasil belajar kognitif peserta didik kelas XI IPA SMA Negeri 6 Bandar Lampung pada materi sistem ekskresi setelah diberi perlakuan. Peningkatan hasil belajar tersebut dipengaruhi oleh faktor eksternal seperti penggunaan strategi pembelajaran juga disebabkan oleh faktor internal seperti kemampuan kognitif yang bisa mempengaruhi daya ingat pada peserta didik saat proses pembelajaran berlangsung.
