Abstract

Population growth, land-use conversion, and the reduction of vegetation cover have led to increasingly frequent floods and droughts in Semarang Regency. These conditions exacerbate surface runoff and reduce the soil’s capacity to store water, resulting in inundation during the rainy season and drought during the dry season. The objective of this study is to determine the location for installing Horizontal Recharge Pipes (HRP), which play an important role, particularly in flood-prone areas, by enhancing groundwater infiltration as a water reserve. The method applied in this research involves calculating the magnitude of runoff discharge in areas with potential flood inundation, which is then simulated with the application of HRP installation to determine the number of HRPs required to reduce flooding. Drought-prone areas were analyzed using satellite imagery to identify suitable HRP locations. In the Klegung watershed, 10 HRP units are required; in the Curug watershed, 460 units; and in the Lodong watershed, 835 units, all using a 12-inch diameter. Drought analysis using Landsat imagery identified dry areas in East Ungaran, Susukan, Suruh, Bancak, and Pringapus subdistricts. The installation points for HRPs can be prioritized based on areas experiencing inundation or drought. The implementation of HRPs is expected to infiltrate surface runoff effectively, thereby reducing flood risk while simultaneously increasing groundwater availability in Semarang Regency.

Abstract

Latar Belakang: Dawet ireng merupakan minuman tradisional khas Purworejo yang menggunakan tepung oman sebagai pewarna hitam alami pada butiran cendol. Praktik penggunaan tepung oman yang bersifat tradisional serta potensi penyalahgunaan Bahan Tambahan Pangan (BTP) pewarna menimbulkan isu keamanan pangan pada produk UMKM dawet. Tujuan: Meningkatkan pengetahuan pelaku UMKM Dawet Purworejo mengenai BTP pewarna pangan dan keamanan tepung oman sebagai dasar penguatan sistem keamanan pangan. Metode: Sosialisasi meliputi survei pendahuluan, ceramah interaktif, dan diskusi terkait regulasi BTP pewarna, risiko polisiklik aromatik hidrokarbon (PAH) seperti benzo[a]pyrene pada tepung oman, serta prinsip higiene dan sanitasi pangan. Evaluasi dilakukan menggunakan kuesioner pre-test dan post-test yang dianalisis secara deskriptif. Hasil: Rata-rata skor pengetahuan meningkat dari 32% menjadi 94%, melampaui target peningkatan minimal 50%. Kesimpulan: Sosialisasi terstruktur mengenai BTP pewarna dan tepung oman efektif meningkatkan kapasitas pengetahuan pelaku UMKM dawet dan mendukung penguatan keamanan pangan pada usaha pangan tradisional.

Abstract

Permasalahan pengelolaan sampah di wilayah pesisir masih menjadi tantangan lingkungan yang memerlukan keterlibatan aktif masyarakat. Desa Surodadi, Kecamatan Sayung, Kabupaten Demak merupakan kawasan pesisir yang menghadapi permasalahan sampah akibat keterbatasan sistem pengelolaan serta dampak banjir rob dan abrasi pantai. Kondisi tersebut menyebabkan pengelolaan sampah rumah tangga belum dilakukan secara terpadu dan partisipatif. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan, kesadaran, dan partisipasi masyarakat melalui program pemberdayaan berbasis bank sampah. Metode pelaksanaan kegiatan dilakukan selama empat bulan melalui tahapan perizinan dan survei lapangan, persiapan program, pelaksanaan sosialisasi dan pendampingan, pembentukan kelembagaan bank sampah, serta evaluasi kegiatan. Evaluasi dilakukan menggunakan metode pre-test dan post-test untuk mengukur tingkat pengetahuan serta kepedulian masyarakat terhadap pengelolaan sampah. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada tingkat pemahaman masyarakat mengenai pengelolaan sampah, dengan nilai rata-rata meningkat dari 75% pada tahap awal menjadi 95,5% setelah pelaksanaan program. Selain itu, terbentuk kembali kelembagaan bank sampah sebagai sarana pengelolaan sampah berbasis masyarakat. Program ini terbukti mampu mendorong perubahan perilaku masyarakat dalam melakukan pemilahan dan pengelolaan sampah sejak dari sumbernya. Kegiatan pengabdian ini memberikan kontribusi dalam penguatan kapasitas masyarakat serta pengembangan sistem pengelolaan sampah yang berkelanjutan di wilayah pesisir. Model pemberdayaan melalui bank sampah berpotensi untuk direplikasi pada wilayah lain dengan karakteristik permasalahan serupa.

Abstract

Flooding is a common issue affecting various regions in Indonesia, particularly in densely populated urban areas. High rainfall intensity leading to river overflow, dense residential settlements, and inadequate drainage systems and environmental conditions are key factors contributing to flood disasters. This study aims to analyze the drainage capacity of the Kali Kencing channel, evaluate the existing drainage system, and assess the potential flood reduction through the implementation of a polder system within the Kali Kencing drainage network. A qualitative research method is applied, incorporating hydrological and hydraulic analyses, which are further simulated to model the relationship between retention pond storage and optimal pump capacity. The analysis reveals that the current drainage capacity of Kali Kencing is insufficient to convey the existing discharge, resulting in runoff that affects residential areas and agricultural fields. The existing system only includes a small long-storage facility and lacks adequate pumping capacity. Therefore, a retention pond covering 4.5 hectares is proposed to temporarily store excess water during elevated water levels in the Wulan River. Simulation results indicate that the retention pond can reduce peak flood discharge from 65.10 m³/s to 36.00 m³/s, achieving a 55% reduction. Additionally, the installation of two flood pumps with a capacity of 5 m³/s each, along with one pump of 1 m³/s for low-flow operation, is recommended to enhance system performance.

Abstract

Access to water with acceptable quality remains an important issue in rural communities that rely on surface water or groundwater for domestic activities. This study evaluated the performance of a simple gravity-fed filtration system using gravel, silica sand, activated carbon, and manganese zeolite as filter media for improving water quality in Kalikayen Village, East Ungaran District, Semarang Regency. Water samples were collected before and after filtration and analyzed at the Health Laboratory Technical Implementation Unit of Semarang City for total ammonia, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), and pH. The results showed that filtration reduced total ammonia from 0.78 to 0.17 mg/L and TSS from 50 to 3 mg/L, indicating substantial removal of suspended and ammonia-related contaminants. However, BOD increased from 0.44 to 1.19 mg/L, while COD remained below 0.50 mg/L before and after filtration. The pH decreased slightly from 7.60 to 7.46 but remained near neutral. Overall, the multi-media filtration system substantially improved selected water-quality characteristics, particularly TSS and total ammonia, although the increase in BOD indicates that further investigation of organic matter behavior and filter operation is required. The findings demonstrate the potential of a low-cost gravity-fed filtration system as a practical preliminary water-treatment option for rural communities.
