Abstract

This study investigated the potential of anaerobic digestion sludge derived from palm oil mill effluent (POME) to enhance the structure of sandy soils in the Samas Coastal Area, Bantul Regency, Yogyakarta. Sandy soils, having low water retention and nutrient-holding capacity, present significant challenges for sustainable agriculture. By applying different volumes of digestate (0 ml, 50 ml, 100 ml, 200 ml, 400 ml, and 800 ml per kilogram of soil) in a 30-day greenhouse experiment, this research assessed the impact of POME sludge on soil structure improvements, particularly focusing on aggregation, porosity, and bulk density. Treatments with higher digestate volumes, especially 800 ml/kg, yielded substantial improvements in soil aggregation, contributing to better moisture retention. Enhanced aggregation facilitated improved water retention and root penetration, indicating that anaerobic digestion sludge could effectively amend sandy soil limitations. These findings underscore the potential of POME-derived organic amendments as sustainable soil conditioners, offering a dual benefit of waste valorization and enhanced agricultural productivity for marginal soils in coastal areas.

Abstract

Palm oil mill effluent (POME) poses a significant environmental threat due to its high organic and inorganic load. This study introduces a novel integration of rice husk ash (RHA) coagulation and electrocoagulation (EC) for sustainable POME remediation. Thermally treated at 500 °C for two hours, RHA was characterized via FTIR, revealing active silica-based functional groups conducive to charge neutralization and adsorption. Treatment experiments employed 9.3 g/L RHA and aluminum electrodes spaced 20 mm apart under varying currents of 10, 15, and 20 A over 15, 30, and 45 minutes. At the highest tested condition (9.3 g/L RHA, 20 A, 45 minutes), the integrated process achieved 78% total solids (TS) and 43% chemical oxygen demand (COD) removal, surpassing individual RHA coagulation removed 34% TS and 17% COD, while EC alone achieved 43% TS and 18% COD removal. The superior performance stems from synergistic flocculation, adsorption, and electroflotation. Compared to conventional methods, the combined RHA–EC system offers faster treatment, lower chemical and energy demands, and improved sustainability. These findings suggest a scalable solution for decentralized POME treatment, particularly in resource-limited palm oil-producing regions.

Abstract

This study examines the role of teachers in forming the Pancasila Student Profile, with a focus on the dimension of cooperation (gotong royong) in elementary schools. Employing a qualitative descriptive approach, data were collected through observations, in-depth interviews, and document analysis at SD Negeri 4 Ujungpandan. The primary aim of the study is to describe how teachers serve as change agents and moral exemplars in instilling the value of cooperation while fostering positive character development among students. Findings indicate that the implementation of cooperative learning methods, such as group discussions, and thematic projects, significantly enhances active participation, empathy, and collaboration among students. Teachers who create interactive classroom environments and apply systematic evaluations using rubrics and regular reflective sessions are proven to optimize the development of social character and collective responsibility. On the other hand, the study identifies challenges such as individual differences among students and the influence of advanced technology that tends to promote solitary learning. Furthermore, inadequate support facilities are noted as obstacles in executing cooperative learning. These findings emphasize that innovative pedagogical strategies and adaptive internal policies are crucial for integrating the value of gotong royong into teaching practice. The practical recommendations are expected to guide educators and policymakers in strengthening the role of teachers as mediators between theory and practice, thereby cultivating a generation of students who excel academically while embodying strong communal values and solidarity. ABSTRAKPenelitian ini mengkaji peran guru dalam pembentukan Profil Pelajar Pancasila dengan fokus pada dimensi gotong royong di sekolah dasar. Dengan menggunakan pendekatan kualitatif deskriptif, data dikumpulkan melalui observasi, wawancara mendalam, dan studi dokumentasi pada SD Negeri 4 Ujungpandan. Tujuan utama penelitian adalah untuk menggambarkan bagaimana guru berperan sebagai agen perubahan dan teladan moral dalam menanamkan nilai gotong royong serta mengembangkan karakter positif di antara siswa. Hasil penelitian menunjukkan bahwa penerapan metode pembelajaran kooperatif, seperti diskusi kelompok dan proyek tematik, secara signifikan meningkatkan partisipasi aktif, empati, dan kolaborasi antarsiswa. Guru yang menciptakan lingkungan kelas interaktif dan menerapkan evaluasi sistematis melalui rubrik serta sesi refleksi rutin terbukti berhasil mengoptimalkan perkembangan karakter sosial dan tanggung jawab kolektif. Di sisi lain, penelitian ini mengidentifikasi tantangan berupa perbedaan kemampuan individual siswa dan pengaruh kemajuan teknologi yang cenderung mendorong pembelajaran secara individual. Selain itu, keterbatasan fasilitas pendukung juga menjadi hambatan dalam pelaksanaan pembelajaran kooperatif. Temuan tersebut menekankan bahwa inovasi pedagogis dan kebijakan internal yang adaptif sangat diperlukan untuk mengintegrasikan nilai gotong royong ke dalam strategi pengajaran. Rekomendasi praktis yang dihasilkan diharapkan dapat menjadi acuan bagi pendidik dan pembuat kebijakan dalam memperkuat peran guru sebagai mediator antara teori dan praktik, sehingga terbentuk generasi pelajar yang tidak hanya unggul secara akademik, tetapi juga memiliki karakter kebersamaan dan solidaritas yang kokoh.

Abstract

Kekerasan seksual dan Narkotika yang semakin marak terjadi saat ini cukup menjadi sorotan. Narkoba dapat membahayakan kehidupan manusia, jika dikonsumsi dengan cara yang tidak tepat, bahkan dapat menyebabkan kematian. Narkoba memiliki dampak negative yang sanggat luas, baik secara fisik maupun psikis, ekonomi, sosial budaya hankam, dan lain sebagainya. Kekerasan seksual pada wanita baik anak-anak dan kaum remaja juga sangat memprihatinkan. Upaya pencegahan kekerasan seksual remaja dilakukan dengan memberikan materi dampak-dampak negatif baik dari penggunaan narkoba maupun kekerasan seksual. Untuk meningkatkan kesadaran diri anak-anak remajan di Tolitoli dapat dilakukan dengan cara mendorong generasi muda khususnya siswa siswi MTs dan MA Ponpes Al-Amin Desa Labonu untuk mengikuti sosialisasi hukum tentang pencegahan kekerasan seksual dan bahaya narkoba di usia remaja. Kegiatan pengabdian kepada masyarakat ini dilaksanakan pada hari sabtu tanggal 2 september 2023. Bertempat di balai Desa Labonu, Kecamatan Basidondo, Kabupaten Tolitoli, Sulawesi Tengah. Prosedur kegiatan ini yaitu pertemuan langsung, Hasil penyuluhan ini menunjukan keseluruhan siswa dan siswi telah memahami potensi dan resiko narkoba dan kekerasan seksual, dan diharapkan setelah kegiatan ini dapat mengetahui bahaya dan dampat dari narkoba dan kekerasan seksual.

Abstract

With the goal of entering Indonesia’s golden dream 2045 in mineral technology and utilizations, expansive researches covering both experimental and theoretical aspects are urgently required. Here, we provide theoretical study on structural and mechanical properties of various nickel-based alloys based on first-principles, density functional theory (DFT) technique. First, we evaluate the accuracy of several exchange-correlation functionals (LDA-PZ, GGA-PBE, GGA-PBEsol) by comparing the calculated lattice constants for each system with the known experimental results. Based on the best functional, we analyze structural changes caused by the mixture of different atom to the principal element of nickel. Finally, we derived the related mechanical properties for all systems based on the calculated elastic constants. Furthermore, the elastic constants can also be used to predict the stability of alloy structure.
