Abstract

Penelitian tentang Uji Kandungan Unsur Hara Ca, Mg Dan Fe Pupuk Organik Cair Dari (POC) Limbah Batang Pisang Kepok (Musa acuminata balbisiana Colla) bertujuan untuk mengetahui apakah Pupuk Organik Cair (POC) dari limbah batang pisang kepok (Musa acuminata balbisiana Colla) mengandung unsur hara Ca, Mg dan Fe serta mengetahui kandungan unsur hara Ca, Mg dan Fe dalam Pupuk Organik Cair (POC) dari limbah batang pisang kepok. Penelitian ini diuji secara kualitatif dan kuantitatif. Hasil uji kualitatif menunjukkan Pupuk Organik Cair (POC) dari limbah batang pisang kepok (Musa acuminata balbisiana Colla) mengandung unsur hara Ca, Mg dan Fe. Analisis kuantitatif diukur menggunakan instrument Atomic Absorption Spectroscopy (AAS). Hasil uji kuantitatif Pupuk Organik Cair (POC) menunjukkan kandungan unsur hara Ca 54,3963 ppm, Mg 52,0727 ppm dan Fe 4,2715 ppm.

Abstract

This community service program aimed to enhance the knowledge and technical skills of freshwater fish farmers in Purwasari Village, Dramaga District, Bogor Regency, in producing independent fish feed using locally available ingredients. The program was implemented by the Forum Wacana IPB University team in collaboration with a feed expert from Sultan Ageng Tirtayasa University. The activities consisted of counseling, technical training, and mentoring using a participatory learning approach, allowing participants to be actively involved in every stage of the program. Evaluation through pretest and posttest demonstrated a significant improvement, with an average knowledge increase of 38.1%, particularly in technical understanding and group institutional capacity. Participants showed strong enthusiasm and commitment to continue producing independent feed collectively to reduce production costs and improve business efficiency. The program effectively strengthened farmers’ economic independence and supported the national policy on sustainable fish feed self-sufficiency.

Abstract

This study examines the correlation between digital project-based learning and self-confidence on Arabic language learning achievement. Employing a 2 × 2 treatment-by-level research design, the implementation of digital project-based learning demonstrated a positive effect on student learning outcomes. This can be seen in the score differences between classes that applied digital project-based learning and those that used project-based learning without digital assistance. The average score of the experimental class was 60.31, while the control class achieved an average score of 35.69. This finding was supported by the results of a two-way ANOVA, which showed a significance value of 0.000 < 0.05, indicating a significant difference in Arabic learning achievement between students taught using digital project-based learning and those taught without digital assistance. Similarly, self-confidence also showed a positive effect on Arabic learning achievement. Students with high self-confidence achieved higher scores than those with low self-confidence, with average scores of 63.85 and 32.15, respectively. This result was further supported by the two-way ANOVA test, which yielded a significance value of 0.000 < 0.05, indicating a significant difference in Arabic learning achievement between students with high and low self-confidence.
