Abstract

Pembangunan gapura di Desa Sukmajaya, Kecamatan Tajurhalang, melalui program Kuliah Kerja Nyata (KKN) Tahun 2025 merupakan bentuk nyata dari kolaborasi mahasiswa, aparat desa, dan masyarakat dalam mewujudkan pembangunan berbasis partisipasi. Gapura yang dibangun tidak hanya memiliki fungsi sebagai pintu gerbang dan penanda wilayah, tetapi juga memuat makna filosofis sebagai simbol identitas, kebersamaan, dan nilai gotong royong masyarakat Desa Sukmajaya. Proses pembangunan dilakukan secara terencana melalui musyawarah desa, perencanaan desain bersama, serta pelaksanaan dengan melibatkan karang taruna, tokoh masyarakat, dan perangkat desa. Penelitian atau laporan ini bertujuan untuk mendeskripsikan proses pembangunan gapura mulai dari tahap perencanaan, pelaksanaan hingga dampak yang dirasakan masyarakat setelahnya. Keterlibatan aktif masyarakat menjadi aspek penting dalam menjaga keberlangsungan dan rasa memiliki terhadap hasil pembangunan. Hasil pembangunan gapura menunjukkan adanya peningkatan estetika lingkungan, penguatan identitas desa, serta terciptanya rasa kebanggaan kolektif di kalangan warga. Dengan demikian, pembangunan gapura bukan sekadar infrastruktur fisik, tetapi juga simbol kebersamaan dan representasi jati diri Desa Sukmajaya.

Abstract

The Putri Cempo landfill serves as the final disposal site for organic and inorganic waste. Waste from the landfill can dissolve and settle in river sediments, potentially accumulating heavy metals like iron (Fe) and manganese (Mn), which bind easily to organic matter. This study aims to determine the content of Iron (Fe) and Manganese (Mn) in rivers around the Putri Cempo landfill. The concentration of Fe and Mn was analyzed using Atomic Absorption Spectrometry (AAS) referring to SNI 6989.84:2019,   with sediment sampling conducted in rivers around the Putri Cempo landfill. Sediment sampling was conducted in these rivers, revealing Fe levels of 1519.414245 mg/L and Mn levels of 130.033 mg/L. Analysis indicates that Fe concentrations exceed the established quality threshold, while Mn levels remain below it. Heavy metals like Fe and Mn negatively impact abiotic and biotic environments, including human health and agricultural productivity. Elevated heavy metal levels disrupt ecosystem balance and pose health risks, making their management crucial. Reducing heavy metals in river sediments near the landfill is essential. Remediation efforts using bioremediation and phytoremediation technologies can help mitigate these impacts. Ongoing efforts are necessary to control heavy metal contamination in river sediments, ensuring ecosystem stability and public health.

Abstract

Bioplastics that are biodegradable offer an environmentally friendly alternative. One type of bioplastic being developed is Polybutylene Adipate-Co-Terephthalate (PBAT), an aliphatic-aromatic polyester capable of decomposting through microbial activity. This study aims to analyze the potential of bioplastic waste as a compost mixture ingredient and determine the optimal composition of bioplastic waste mixtures for compost production. The study utilized a Completely Randomized Design (CRD) method. The quality of the compost made from bioplastic waste mixtures was evaluated based on SNI 7763:2024 standards, with parameters including pH, temperature, additional substances, and chemical content such as nitrogen (N), phosphorus (P), potassium (K), and organic carbon (C-organic). The composting process lasted 60 days, using mixtures of bioplastics and cow manure organic waste in proportions of 95:5, 90:10, 85:15, 80:20, 75:25, and 70:30, each weighting 1 kg. Some mixtures were supplemented with 30 mL of activated EM4 to accelerate decomposition, while the control group used only cow manure. The results indicated that the compost produced generally met SNI 7763:2024 standards. The most effective composition was 80% organic waste, 20% bioplastic, and 30 mL of EM4. This composition achieved N+P2O5+K2O levels of 2.88%, C-organic content of 30.46%, moisture content of 24.60%, and a pH of 7.60.
