Abstract

Biogas is a renewable energy source that can be produced from organic waste, such as water hyacinth and cow dung. Utilizing these two materials through co-digestion has the potential to increase biogas production due to a better nutrient balance. This study aims to analyze the effect of the substrate ratio on the volume of biogas produced through anaerobic digestion. The method used is a Systematic Literature Review (SLR) by reviewing five relevant scientific articles based on certain inclusion and exclusion criteria. The parameters analyzed include the substrate ratio, biogas volume, and hydraulic retention time (HRT) or fermentation duration. The results of the study indicate that the substrate ratio has a significant influence on biogas production. Ratios that are close to balance, such as 50:50 and 47:53, tend to produce more optimal and stable biogas volume. Conversely, unbalanced ratios, such as 33:67, show varying results depending on operational conditions. Differences in biogas volume between studies are also influenced by other factors, such as retention time, raw material characteristics, and process conditions such as pH and temperature. The lignocellulose content of water hyacinth can inhibit the degradation process if not balanced with an adequate nitrogen source from cow dung. In conclusion, a balanced substrate ratio plays a crucial role in increasing biogas production, but it needs to be supported by controlling other operational parameters to achieve optimal and sustainable results.

Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk mendorong pelaku Usaha Mikro, Kecil, dan Menengah (UMKM) agar naik kelas melalui legalisasi usaha. Permasalahan utama yang dihadapi UMKM desa adalah keterbatasan dalam pengurusan Nomor Induk Berusaha (NIB) karena minimnya pemahaman dan keterampilan dalam menggunakan sistem Online Single Submission (OSS). Kegiatan dilaksanakan dengan pendekatan partisipatif-edukatif melalui seminar, tutorial praktik pendaftaran NIB, serta pendampingan langsung kepada pelaku usaha. Hasil kegiatan menunjukkan adanya peningkatan pemahaman dan keterampilan warga, terbukti dengan terbitnya NIB bagi UMKM setempat serta meningkatnya kesadaran akan pentingnya legalitas usaha. Pendampingan juga diperkuat dengan pemanfaatan grup WhatsApp sebagai sarana komunikasi berkelanjutan. Dengan demikian, program ini berhasil memberikan output nyata berupa legalitas usaha yang sah sekaligus menjadi fondasi bagi penguatan daya saing UMKM desa. This community service activity aims to encourage Micro, Small, and Medium Enterprises (MSMEs) to upgrade through business legalization. The main problem faced by village MSMEs is the limitation in processing Business Identification Numbers (NIB) due to a lack of understanding and skills in using the Online Single Submission (OSS) system. The activity was implemented using a participatory-educational approach through seminars, practical tutorials on NIB registration, and direct mentoring for business actors. The results of the activity showed an increase in community understanding and skills, as evidenced by the issuance of NIBs for local MSMEs and increased awareness of the importance of business legality. The mentoring was also strengthened using WhatsApp groups as a means of ongoing communication. Thus, this program successfully delivered tangible output in the form of legal business registration while also serving as a foundation for strengthening the competitiveness of village MSMEs.

Abstract

Indonesia has a wealth of flora with great potential to be developed as a functional food ingredient with economic value. One local plant that has this potential is the butterfly pea flower (Clitoria ternatea), which is known for its attractive natural color and beneficial bioactive compounds. This community service activity aims to introduce diversified butterfly pea flower processing to students through training in making food products as a home business idea based on local potential. The training was carried out using the method of material presentation, interactive discussions, and organoleptic product testing. The products developed include Azure Petal Tea, Citrus Spice Infusion, Blue Velvet Milk Tea, and Indigo Dream Pudding. The processing process is carried out using simple methods that are easy to apply. The results of the activity showed that participants were highly enthusiastic about the process of creating product characteristics and demonstrated a better understanding of the potential for diversifying butterfly pea flowers into value-added food products.
