Abstract

The primary goal of this study was to investigate the biosorption performance of biochar derived from exhausted kahwa coffee (EKC) on removing heavy metal ion, Cd²⁺ in the solution. The operational parameters, for instance pH, dosage and contact time, were varied in a certain range and the efficiency and the capacity of removal were determined. The pH was in a range of 5 – 11, while the biochar dosage in a range of 0.075 – 0.15 g and the contact time was in between 30 – 180 minutes. The batch biosorption test showed that the EKC biochar had higher removal performance in alkaline condition, with a proposed pH of 10. Meanwhile, the applied dosage showed that addition of 0.1 g EKC biochar was more effective than adding more dosage. Furthermore, the batch experiments showed that 60 minutes of biosorption process resulted in more effective removal compared to the longer biosorption time. According to the ANOVA analysis on the three conditions, it was shown that the pH and contact time had significant effects on the removal performance of EKC biochar on cadmium ion in the solution.  Keywords: Biochar, biosorption, Exhausted kahwa coffee, Heavy metal ion, Operational parameters.

Abstract

Akuaponik merupakan sistem budidaya terintegrasi yang mengombinasikan teknik hidroponik dengan budidaya ikan dalam ekosistem sirkulasi tertutup, di mana air limbah hasil metabolisme ikan dimanfaatkan sebagai sumber nutrisi alami bagi tanaman. Berbeda dari hidroponik konvensional yang bergantung pada larutan AB mix, sistem ini menawarkan alternatif yang lebih ramah lingkungan dan berkelanjutan. Penelitian ini bertujuan untuk mengevaluasi pengaruh tiga desain sistem hidroponik DFT berbeda terhadap pertumbuhan tanaman pakcoy (Brassica rapa L.), yang dikenal bernilai ekonomis dan bergizi tinggi. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, dan bobot segar tanaman. Data dianalisis menggunakan uji ANAVA satu arah pada taraf signifikansi 5%. Hasil menunjukkan adanya perbedaan nyata antar model, di mana sistem piramida memberikan hasil terbaik dengan rata-rata tinggi tanaman 22,4 cm, jumlah daun 8,6 helai, dan bobot segar 74,8 gram. Temuan ini menunjukkan bahwa desain sistem DFT berpengaruh signifikan terhadap produktivitas tanaman dalam sistem akuaponik.

Abstract

Climate change is a global issue that has a significant impact, especially for agricultural countries such as Indonesia. The agricultural sector is highly vulnerable to changes in climate patterns, temperature, and rainfall, which affect production, food security, and community welfare. The younger generation has a strategic role in facing these challenges due to its large numbers and potential as change agents. In 2024, 31.02% of Indonesia's population will be between 15 and 29 years old. Therefore, raising climate awareness among the younger generation is crucial. This program aims to increase the understanding and capacity of the younger generation through education and climate-smart agricultural practices, including climate change mitigation and adaptation to prevent food crises and stunting. The activities were designed as Pengabdian Kepada Masyarakat Terintegrasi dengan Kegiatan Mahasiswa (PKM-TKM), involving KKN students, lecturers, practitioners, and village officials. They were carried out at SMA 1 Basa Ampek Balai, Basa Ampek Balai Tapan District, Pesisir Selatan. The solutions offered include education and mitigation practices such as converting waste into compost, tree planting, and adaptation through planting calendars and biopori infiltration pits. The activities that have been carried out have succeeded in increasing the understanding, skills, and awareness of the younger generation regarding climate change issues. Through socialization, training, and technology application, participants gained theoretical knowledge and practical experience in waste processing into compost, making biopori holes, tree planting, utilizing organic mulch, processing local foods, and fish farming in buckets (Budikdamber). This activity has positively impacted participants' capacity to face the challenges of climate change while strengthening the role of the younger generation as agents of environmental and public health change.

Abstract

Pincuran Gadang Farmers Group, a part of the BUMNag Balai Panjang enterprise in Lareh Sago Halaban District, Lima Puluh Kota Regency, faced the problem of low sales performance in its Jawarandu goat business due to a conventional marketing approach. Over the past year, the group’s average sales reached only two to three goats per month, mainly relying on word-of-mouth and limited Facebook promotion. This community service program aimed to enhance the group’s income and business competitiveness through the implementation of a hybrid marketing strategy combining conventional and digital promotion methods. The activities included field observation, participatory mentoring, the creation of printed brochures for goat marketing, and the development of an official Instagram account as a digital promotion tool. The results indicated improvements in members’ understanding and skills in managing promotional media, stronger business branding, and increased interaction with potential customers within and beyond the local community. Furthermore, the adoption of digital marketing expanded the group’s market reach and improved consumer trust in local livestock products. The integration of printed and digital promotion proved to be an effective approach to strengthening the economic independence of smallholder livestock farmers while fostering the community’s digital capacity. The sustainability implication of this program lies in the establishment of a sustainable community marketing model that can be replicated by other rural farmer groups to promote inclusive and resilient agribusiness development.
