Abstract

Household organic waste can be used as raw material to produce Liquid Organic Fertilizer (LOF) as an effort to reduce the amount of solid waste disposed of at Temporary Disposal Sites (TPS). The organic fertilizer produced can be reused in home gardens, such as for ornamental or fruit plants. In addition to being used as fertilizer, LOF can be used as a starter for making other organic fertilizers or as a decomposer in the production of compost. The community empowerment activities in making LOF aim to raise awareness of the potential of household waste as a valuable resource. Through a participatory approach, the community is encouraged to actively engage in the process of converting waste into LOF, which benefits agriculture and the environment. The empowerment and community development activities regarding the application of simple LOF production were conducted at RT 03 RW 09, Tanjung Berok, Kurao Pagang Sub-District, Padang City. The activities included socialization, education, and practical training on converting household organic waste into LOF using buckets as containers. As a result of these activities, the community gained increased knowledge in processing household organic waste into LOF and Microorganism Liquid (MOL), which can be used for fruit and ornamental plants in their yards and residential areas. The attendees realized the importance of protecting the environment by managing their household waste and avoiding disposing of waste into water channels.

Abstract

Abstract: Microplastics have become a global concern due to their wide distribution and ecological effects. Understanding the interactions between microplastics and ecosystems is important for environmental risk assessment. This study analyzed the abundance and distribution of microplastics in Lake Singkarak. Substantial microplastic research is still lacking for freshwater biota, so a study was conducted to determine the level of microplastic pollution in bilih fish tissue. The fish's size, weight, and sampling point were studied about microplastic uptake through two channels, digestion and respiration. From the results, the types of polymers identified in this study were polyethylene, polyvinyl chloride, and polyethylene terephthalate. Overall, 7.14% - 23.53% (average = 11.48%) of microplastics were identified in the D tract of bilih fish from sixteen different sampling points. While 7.69% - 17.39% (average = 11.85%) of microplastics were identified in the respiration of bilih fish. The highest percentage of the abundance of microplastic forms in the digestions identified was fiber at 70.42% and 66.82% in the digestions. At the same time, The lowest percentage identified was fragmented, with an average abundance of 29.58% in digestion and 33.32% in respiration. In conclusion, this study reveals the presence and impact of microplastics in Lake Singkarak, West Sumatra, on the bilih fish (Mystacoleucus padangensis). By examining the fish's digestive and respiratory systems and using FT-IR Spectroscopy, the research highlights the ecological and economic implications of microplastic pollution. These findings emphasize the need for targeted conservation and management strategies.Abstrak: Mikroplastik telah menjadi perhatian global karena distribusinya yang luas dan efek ekologisnya. Pemahaman tentang interaksi antara mikroplastik dengan ekosistem dinilai penting untuk penilaian risiko lingkungannya. Penelitian ini menganalisis kelimpahan dan distribusi mikroplastik di Danau Singkarak. Penelitian mikroplastik secara substansial masih sedikit untuk biota air tawar maka dilakukan penelitian untuk menentukan tingkat polusi mikroplastik pada jaringan ikan bilih. Ukuran, berat, dan titik sampling ikan diteliti dalam kaitannya dengan jerapan mikroplastik melalui dua saluran, yaitu digestif (pencernaan) dan respirasi (pernapasan). Dari hasil penelitian, jenis polimer yang teridentifikasi dalam penelitian ini adalah jenis polietilen, polivinil klorida, dan polietilen tereftalat. Secara keseluruhan 7,14% - 23,53% (rata-rata = 11,48%) mikroplastik teridentifikasi pada digestif ikan bilih dari enam belas titik sampling yang berbeda. Sementara 7,69% - 17,39% (rata-rata = 11,85%) mikroplastik teridentifikasi pada respirasi ikan bilih. Persentase kelimpahan bentuk mikroplastik tertinggi pada digestif yang diidentifikasi adalah fiber sebesar 70,42% dan 66,82% pada digestif. Sementara persentase terendah yang diidentifikasi adalah fragment dengan rata-rata kelimpahan sebesar 29,58% di digestif dan 33,32% di respirasi. Sebagai kesimpulan, penelitian ini mengungkap keberadaan dan dampak mikroplastik di Danau Singkarak, Sumatera Barat, pada ikan bilih (Mystacoleucus padangensis). Dengan memeriksa sistem pencernaan dan pernapasan ikan serta menggunakan Spektroskopi FT-IR, studi ini menunjukkan implikasi ekologis dan ekonomi dari polusi mikroplastik. Temuan ini menekankan perlunya strategi konservasi dan pengelolaan yang terarah.

Abstract

Microplastic pollution accumulates in the marine environment, thus impacting the health of marine organisms. The purpose of this study was to analyze and identify the abundance and characteristics of microplastics in Horse-Eye Jack fish (Caranx latus) in coastal Bungus Bay, West Sumatra. Fish samples were taken at three different locations, namely, Sako beach, Caroline Beach, and the east side of Bungus Bay. The average abundance of microplastics in horse-eye Jack fish samples in digestive is 21.63 ± 3.99 particles/fish, and in respiration, 9.23 ± 1.92 particles/fish. The shape identified forms of microplastics are fibers, films, fragments, granules, and foam, and the dominant color of microplastics is red. The most common size of microplastics found was <0.5 mm. FT-IR spectroscopy analysis showed that the polymer types of microplastics found were PE, PVC, PET, and PS. Statistical tests showed differences between the abundance of microplastics in two pathways of microplastic uptake (digestive and respiration), and the sampling location P<0.05. The results showed that microplastics were found in all Horse-Eye Jackfish samples in Bungus Bay, West Sumatra.These findings highlight microplastics' harm to the marine ecosystem and the necessity of managing plastic waste if we hope to avoid future plastic pollution catastrophes

Abstract

PDAM Malang has legally and technically provided potable drinking water through the Zona Air Minum Prima (ZAMP) program. Although most service areas have met ZAMP requirements, several areas still require improvements in service quality. The development of potable drinking water services requires substantial investment and faces technical, operational, and financial risks that may affect project performance and sustainability. This study analyzes the risks associated with improving potable drinking water services in PDAM Malang under a Public Private Partnership (PPP) scheme, focusing on risk allocation and mitigation strategies throughout the project lifecycle. A mixed-methods approach was employed, combining qualitative and quantitative techniques. Risks were identified through semi-structured interviews with five experts selected using purposive sampling. Risk assessment used the water sector risk matrix developed by PT Penjaminan Infrastruktur Indonesia, based on probability and impact scores ranging from 1 to 5. The results show that the dominant risks during the pre-construction stage were land acquisition delays and design errors, each with a risk score of 12. During construction, the highest risk was unclear output specifications, with a risk score of 20. In the operational stage, inaccurate life-cycle cost estimation and low initial service uptake were identified as the most critical risks, each scoring 25. The operational stage exhibited the highest overall risk level and was predominantly allocated to the private sector partner. These findings highlight the importance of appropriate risk allocation and effective mitigation strategies to ensure the sustainable delivery of potable drinking water services under a PPP framework.

Abstract

Microplastic pollution in freshwater ecosystems has become a pressing global environmental health issue, given potential to accumulate in aquatic food chain and pose health risks to aquatic organisms and to humans who consume fishery products. Microplastics are among the most commonly found pollutants in freshwater and have the potential to affect aquatic organisms. Lake Singkarak is potentially exposed to microplastic pollution from various surrounding anthropogenic activities. This study aimed to analyze the abundance and characteristics of microplastics in surface water and to compare them with the characteristics of microplastics in bilih fish based on secondary data. Water samples were collected in triplicate from three locations representing a river inlet, a residential area, and a tourism area. Samples were analyzed using chemical extraction and visual identification under a microscope. The parameters observed included the number and shape of microplastics. Microplastics were detected at all sampling locations, with abundance ranging from 9.33±1.15 to 11.67±4.51 particles/L. The microplastics found were dominated by fiber and fragment shapes, with fiber being the most dominant. The highest abundance was found at the river inlet and tourism area locations. Comparison with microplastic data on bilih fish showed consistent characteristics, particularly the dominance of the fiber shape. This indicates a potential link between the presence of microplastics in the water and exposure in aquatic biota. Thus, Lake Singkarak functions as a medium for the transport and accumulation of microplastics, highlighting the need for improved plastic waste management to reduce potential pollution and its impact on the aquatic ecosystem.
