“…Zhu et al ( 2023) [55] stated that FPW may also contain inhibitory acids that could be managed by co-digestion with high-nitrogen swine faeces. Co-substrates or additives for improved process stability and nutrient balance adjustment should favourably be fed at the very beginning of the anaerobic process [13,49,55,56].…”

Biogas is a renewable energy source generated through the anaerobic digestion (AD) of organic feedstocks. This study aims to quantify the biogas production potential (BPP) of fruit wastes via semi-continuous lab-scale mesophilic AD over a total of 100 days. The feed was composed of 80% banana peelings and 20% pineapple residues, mimicking the waste composition of a Costa Rican fruit processing facility used as a test case. The average loading rate of volatile suspended solids (VSS) corresponded to 3.6 kg VSS·m−3·d−1. Biogas yield and composition were monitored, along with the concentration of ammonium, volatile fatty acids, and pH. Discounting the start-up phase, the BPP averaged to 526 LN (kg VSS)−1 with a methane concentration of around 54%, suggesting suitability of the substrate for AD. We calculated that if upscaled to the Costa Rican test case facility, these values translate into a gross average heat and electricity production via AD of around 5100 MWhel·a−1 and 5100 MWhth·a−1, respectively. Deducting self-consumption of the AD treatment, this is equivalent to 73% of the facility’s electricity demand, and could save about 450,000 L of heavy oil per year for heat generation. To circumvent nitrogen shortage, the addition of a co-substrate such as dry manure seems advisable.

“…Sampah organik juga dapat dimanfaatkan menjadi bahan yang bermanfaat, seperti pakan ikan. Sampah organik yang dapat dimanfaatkan sebagai bahan pakan ikan dan ternak, antara lain limbah sayur dan buah (44%), akar dan umbi (20%), sereal (19%), daging (4%), dan seafood (2%) (Zhu et al, 2023). Menurut Lalramhlimi et al, (2022), limbah sayur dan buah umumnya memiliki nilai protein antara 4-10% dan karbohidrat hingga 80%, sehingga dapat dimanfaatkan sebagai bahan pakan alternatif untuk berbagai jenis ternak, seperti domba, sapi, dan ayam.…”

Banyak sampah dapat dikelola menjadi bahan bakar sumber energi dan pakan ternak yang baik, sehingga menjadi lebih bernilai ekonomis dan menguntungkan, seperti menjadi bahan pakan ikan dan hewan ternak. Sampah seperti limbah makanan memiliki ketersediaan yang melimpah dan belum dimanfaatkan untuk penunjang budidaya ikan dan hewan ternak. Bahan pakan alternatif ini diharapkan mampu membantu masyarakat untuk pembuatan pakan mandiri yang dapat memotong biaya pakan secara efektif dan efisien. Kegiatan pengabdian mengenai pembuatan bahan pakan alternatif dari limbah organik perlu dilakukan. Pemanfaatan sampah menjadi bahan pakan akan meningkatkan nilai efisiensi usaha kegiatan pemeliharaan ternak dan ikan. Pengabdian dilaksanakan di Desa Gunungpring, Kecamatan Muntilan, Kabupaten Magelang, pada September-Oktober 2023. Peserta pengabdian merupakan 15 warga desa, empat mahasiswa, dan sembilan dosen Universitas Tidar. Materi pengabdian terfokus pada sosialisasi jenis limbah organik yang dapat dimanfaatkan sebagai bahan baku pakan. Berdasarkan materi yang disampaikan kepada warga, limbah organik yang dapat digunakan sebagai bahan baku pakan alternatif adalah tepung kepala-tulang ikan, tepung daging-tulang ayam, dan tepung daging-tulang ternak besar (kambing dan sapi). Limbah diproses melalui beberapa tahapan pengeringan dan penepungan. Peserta mempraktekkan pengeringan limbah organik di bawah sinar matahari dan dimasukkan ke dalam oven pada suhu 60-80°C selama 12 jam. Limbah dihancurkan menggunakan food processor (penghancur makanan) dan dikeringkan kembali menggunakan oven pada suhu 80-100°C selama 6-8 jam. Limbah dihaluskan kembali menggunakan mesin penepung, sebelum diformulasikan bersama menjadi pakan. Program pengabdian meningkatkan keterampilan warga dalam efisiensi dan efektivitas pembuatan pakan mandiri, untuk memperoleh keuntungan yang optimal bagi masyarakat.

“…In addition, peels, leaves and branches are considered as waste during harvesting or processing. These wastes are mainly disposed of through landfills and incineration or used as animal feed according to traditional management methods [ 16 , 17 , 18 ]. However, the potential of these portions may be underestimated.…”

Research on the comprehensive utilization of sour jujube and its beneficial properties to human health has attracted extensive attention. This study aims to conduct a bibliometric analysis of the bioactive profile of sour jujube and future trends in applications. The research advancements within this field from 2000 to 2023 were addressed using the Web of Science database and VOSviewer. Among the 322 results, the most frequent keywords of bioactivity are flavonoids, antioxidants, saponins, insomnia, polyphenols, terpenoids and anti-inflammatory; the most studied parts of sour jujube are seeds, fruits and leaves; the published articles with high citations mainly focus on identification, biological effects and different parts distribution of bioactive compounds. The bioactivity of various parts of sour jujube was reviewed considering their application potential. The seeds, rich in flavonoids, saponins and alkaloids, exhibit strong effects on central nervous system diseases and have been well-developed in pharmacology, healthcare products and functional foods. The pulp has antioxidant properties and is used to develop added-value foods (e.g., juice, vinegar, wine). The leaves can be used to make tea and flowers are good sources of honey; their extracts are rich sources of flavonoids and saponins, which show promising medicinal effects. The branches, roots and bark have healing properties in traditional folk medicine. Overall, this study provides a reference for future applications of sour jujube in food and medicine fields.
