Abstract

Limbah cair pengolahan sagu dan tahu mengandung nutrien yang berpotensi dimanfaatkan untuk kultivasi Chlorella sp. Karakterisasi meliputi pH, Chemical Oxygen Demand (COD), total karbon (TC), total nitrogen (TN), dan total fosfor (TP), kemudian limbah cair ditambahkan ke dalam medium NaCl salinitas 28 ppt. Kultivasi dilakukan selama 24 hari pada intensitas cahaya 5000 lux dengan fotoperiode 12:12 jam. Air limbah pengolahan tahu menunjukkan kandungan nutrien lebih tinggi dibandingkan air limbah pengolahan sagu, dengan COD masing-masing 23,49 mg/L dan 12,65 mg/L. Konsentrasi sel maksimum diperoleh pada medium kontrol (MK) sebesar 38 × 10⁵ sel/mL (hari ke-21), diikuti perlakuan suplementasi air limbah pengolahan tahu (MLT) sebesar 34 × 10⁵ sel/mL dan air limbah pengolahan sagu (MLS) sebesar 24,9 × 10⁵ sel/mL. Suplementasi limbah cair tidak meningkatkan pertumbuhan dibandingkan kontrol, yang dapat dipengaruhi oleh kondisi pH asam, rasio C:N yang rendah, serta salinitas tinggi yang berpotensi menimbulkan stres osmotik. Meskipun demikian, kedua jenis limbah tetap mampu mendukung pertumbuhan mikroalga dan menunjukkan potensi integrasi kultivasi mikroalga dengan pengolahan limbah cair secara berkelanjutan.

Abstract

A community service initiative was conducted in Assilulu Village, Central Maluku Regency, aimed at assessing the quality of groundwater used by the local community through physical and chemical parameter testing. Residents rely on groundwater from dug wells and springs as their primary sources for drinking and sanitation, often without knowledge of its quality or safety. Key challenges include potential contamination from seawater intrusion and domestic activities, alongside low public awareness regarding the importance of periodic water quality testing. Consequently, a targeted program involving active partner participation was implemented, comprising public outreach, water sampling, groundwater level (GWL) analysis, laboratory testing, and training on the use of simple water quality testing tools. Physical parameters analyzed included temperature, odor, and total dissolved solids (TDS), while chemical parameters included pH, salinity, CN, PO₄³⁻, SO₄²⁻, K⁺, Ca²⁺, Mg²⁺, Na⁺, Cl⁻, and Mn. Test results were evaluated against drinking water quality standards set by the Regulation of the Minister of Health of the Republic of Indonesia Number 2 of 2023. The study revealed that most groundwater sources in Assilulu Village met drinking water quality standards; however, elevated levels of TDS, Na⁺, and Cl⁻ were observed at Location 1, Location 5, and an old well, indicating seawater intrusion. The initiative resulted in increased community knowledge regarding clean water management and the availability of physical and chemical data; furthermore, partners gained proficiency in using portable water testing equipment, enabling them to continuously monitor the quality of the water they use.

Abstract

Soap has become an essential commodity in society, primarily due to its dual functionality as a cleansing agent for removing cutaneous impurities and as a degreasing medium for food utensils. With the increasing demand for soap, training on small-scale soap production becomes essential. One effective pedagogical approach for such training involves the utilization of educational posters as a primary medium. This community service initiative aims to disseminate comprehensive knowledge regarding chemical constituents and standardized methodologies for liquid soap formulation through poster-based communication. This community service initiative was conducted at SD Negeri 292 Maluku Tengah, involving teachers and educational staff as the primary participants. The program implemented a Service-Learning (SL) methodology, which followed a structured framework consisting of three distinct phases: planning, implementation, and evaluation. The results of this community service initiative demonstrated a high level of engagement among participants toward the poster-based education on liquid soap formulation. Participants acquired comprehensive insights regarding raw material selection, production methodologies, and budget estimation analysis. The project team demonstrated the pre-formulated liquid soap products to the participants, followed by an immediate practical trial session. Based on the cost analysis, the estimated expenditure for producing 50 units of liquid soap was approximately IDR 883,000.00. This calculation offers participants valuable insights into establishing a liquid soap production business. Furthermore, this educational content can be integrated into the entrepreneurship curriculum for students at SD Negeri 292 Maluku Tengah. It can be concluded that this community service program successfully provided education and information on the raw materials, manufacturing processes, and cost estimation of liquid soap via poster media. Through this initiative, SD Negeri 292 Maluku Tengah is expected to adopt poster media as an educational medium for liquid soap production

Abstract

The utilization of local biological resources such as sago grub (Rhynchophorus bilineatus) has attracted attention as an alternative source of oil and protein. However, its high moisture content requires appropriate drying treatment to improve processing efficiency. This study evaluated the effect of drying temperature as a thermal pretreatment on moisture reduction, solvent-free mechanical oil recovery, and protein concentration of press cake from Rhynchophorus bilineatus. Fresh sago grubs were dried at 80°C and 105°C for 18 hours, followed by oil extraction using a solvent-free mechanical press. Moisture content, oil yield, and protein concentration of the samples were analyzed, and statistical analysis was performed using One-Way Analysis of Variance (ANOVA). The results showed that drying temperature significantly affected the measured parameters (p < 0.0001). Drying at 80°C resulted in a higher oil yield (39.36%) compared with 105°C (26.14%). The protein concentration of the press cake from the 80°C treatment reached 39.60%, slightly higher than that from the 105°C treatment (38.30%). These findings indicate that drying temperature influences the processing characteristics of sago grubs, with 80°C providing higher oil yield and protein concentration among the evaluated drying conditions.
