The primary components of this research are the DER Ratio, Current Ratio (CR), ROE Ratio, and TATO Ratio. From 2019 to 2022, data from 185 manufacturing companies listed on the Indonesia Stock Exchange (IDX) were analyzed using a quantitative approach. This research provides an analysis of factors that influence firm value in their operations. The results show that TATO and CR have an insignificant influence on firm value, whereas DER and ROE have a significant impact. Companies that manage their debt and equity capital well tend to be more attractive to investors, as high ROE indicates good profitability, while an appropriate DER indicates effective debt management. This research is useful for investors in selecting more important factors to consider when assessing investment potential in manufacturing companies, as well as for companies in designing strategies to enhance firm value.

Penipisan cadangan energi tak terbarukan mendorong pengembangan sumber energi alternatif yang terbarukan, seperti energi biomassa. Biomassa merupakan bahan organik yang berasal dari makhluk hidup dan mengandung senyawa seperti karbohidrat, protein, serta lemak. Selain itu, biomassa juga mengandung lignoselulosa yang memberikan potensi besar sebagai bahan baku produk energi seperti biobriket. Artikel ini bertujuan mengkaji karakteristik biobriket dari limbah lignoselulosa berdasarkan standar mutu SNI briket. Penelusuran data menggunakan studi literatur melalui pencarian di Google Scholar, Research Gate, dan ScienceDirect dengan kata kunci “Limbah lignoselulosa”, “Biomassa”, dan “Biobriket”. Literatur yang dipilih mencakup jurnal dan prosiding seminar nasional ilmiah dalam sepuluh tahun terakhir yang diseleksi menggunakan diagram PRISMA. Jumlah literatur yang digunakan sebanyak 21 jurnal terindeks SINTA, 5 jurnal terindeks Scopus, 2 jurnal terindeks Garuda, 5 jurnal non-indeks yang diperoleh melalui Google Scholar, serta 3 prosiding seminar nasional ilmiah kemudian data yang diperoleh diolah dengan meta-analisis. Hasil penelitian menunjukkan bahwa kualitas briket yang dihasilkan dipengaruhi oleh bahan baku yang digunakan. Biobriket yang memenuhi SNI dapat dinilai berdasarkan kandungan lignoselulosanya, bahan dengan kadar lignin tinggi cenderung memiliki nilai kalor yang lebih besar, sehingga berpotensi menjadi bahan baku yang optimal. Sebaliknya, bahan dengan kandungan lignin rendah memiliki potensi energi yang lebih rendah saat pembakaran. Secara keseluruhan, limbah lignoselulosa memiliki potensi besar sebagai bahan baku biobriket berkualitas berdasarkan standar mutu SNI, terutama dengan optimasi proses produksi melalui kombinasi bahan baku.

The depletion of non-renewable energy reserves encourages the development of alternative renewable energy sources, such as biomass energy. Biomass is an organic material derived from living organisms and contains biochemical compounds such as carbohydrates, proteins, and fats. Moreover, biomass also contains lignocellulose, which holds significant potential as a raw material for energy products such as bio briquettes. This article aims to examine the characteristics of bio briquettes from lignocellulose waste based on SNI briquette quality standards. Data search using literature studies with searches on Google Scholar, Research Gate, and ScienceDirect with the keywords "Lignocellulosic waste", "Biomass", and "Bio briquettes". The selected literature includes journals and national scientific seminar proceedings from the last ten years, screened using the PRISMA diagram. The literature used was 21 journals indexed in SINTA, 5 journals indexed in Scopus, 2 journals indexed in Garuda, 5 non-indexed journals obtained through Google Scholar, and 3 national scientific seminar proceedings, the data obtained was processed using meta-analysis. The results show that the characteristics of bio briquettes are influenced by the raw material. Bio Briquettes that comply with SNI standards can be assessed based on their lignocellulose content. Materials with high lignin levels tend to have a higher calorific value, making them potentially optimal raw materials. In contrast, materials with low lignin content have lower energy potential during combustion. Overall, lignocellulosic waste has significant potential as a raw material for high-quality bio briquettes based on SNI quality standards, especially through production process optimization by combining various raw materials. Keywords: Bio Briquettes, biomass, lignocellulose waste, SNI quality standards

Pembelajaran Pendidikan Agama Islam (PAI) memiliki peran strategis dalam membentuk karakter dan kepribadian siswa. Evaluasi aspek psikologis, khususnya penilaian afektif, menjadi komponen penting untuk mengetahui sejauh mana nilai-nilai keislaman tidak hanya dipahami, tetapi juga dihayati dan diwujudkan dalam perilaku nyata. Makalah ini membahas pelaksanaan penilaian afektif dalam pembelajaran PAI, jenis instrumen yang digunakan guru, faktor penghambat implementasi penilaian, hubungan antara penilaian afektif dengan pembentukan karakter siswa, serta upaya peningkatan kualitas evaluasi. Hasil pembahasan menunjukkan bahwa penilaian afektif umumnya dilakukan melalui observasi, jurnal sikap, penilaian diri, penilaian teman sebaya, dan skala sikap, namun implementasinya masih belum optimal karena keterbatasan kompetensi guru, jumlah siswa yang besar, kurangnya instrumen terstandar, dan minimnya budaya sekolah yang mendukung. Penilaian afektif terbukti memiliki hubungan erat dengan pembentukan karakter religius siswa karena memberikan dasar bagi pembiasaan, keteladanan, serta penguatan perilaku positif. Untuk meningkatkan efektivitas penilaian, guru memerlukan pelatihan berkelanjutan, dukungan sistem sekolah, instrumen yang terstruktur, serta pemanfaatan teknologi. Evaluasi aspek psikologis yang terencana dan konsisten dapat memperkuat peran pembelajaran PAI dalam membentuk generasi yang berakhlak mulia dan berkarakter Islami.
