Abstract

Municipal solid waste (MSW) disposed of in landfills contains a significant proportion of organic fraction that decomposes into soil-like materials that can be potentially recovered and reused. Landfill mining is an emerging strategy to recover these materials from older waste deposits. Integration of these materials into circular waste practices can therefore reduce landfill volume and recover valuable resources. However, given the heterogeneous nature of waste deposited in landfills over time, concerns arise about the quality and safety of the soil-like material, particularly when intended for use as compost or organic fertilizer. In this study, soil-like material samples (n=4) were collected from two landfill age groups, i.e., younger piles (16–20 years) and older piles (21–25 years). Samples were characterized for chemical properties, physical characteristics, and heavy metal content. The results were then compared with the Indonesian National Standards (SNI) 19-7030-2004 for organic domestic compost and SNI 7763:2024 for solid organic fertilizer. Findings revealed that total NPK content in older material (0.80 ± 0.35%) met the NPK threshold for organic domestic compost (≥ 0.70%), whereas younger material (0.40 ± 0.17%) failed. Both age groups failed the NPK requirement for solid organic fertilizer (≥ 2). Furthermore, cadmium (Cd) concentrations in both younger (39.81 ± 11.32 mg/kg) and older (33.47 ± 12.60 mg/kg) materials severely exceeded regulatory thresholds (≤ 3 mg/kg for compost; ≤ 2 mg/kg for fertilizer). Lead (Pb) concentrations (11.32 ± 7.92 mg/kg and 21.43 ± 11.38 mg/kg) complied with statutory standards across both groups. These findings indicate that while mined soil like materials possess resource potential, post-recovery treatments, including inert screening, nutrient enrichment, and heavy metal remediation, are essential prior to land application.

Abstract

Land conversion impacts reducing the catchment area and increasing surface runoff. The zero delta Q policy (ZDQP) regulates that each building manages runoff water within the building area. This study aims to design zero runoff stormwater management system and assess their theoretical effectiveness based on the developmental research approach from Richey & Klein, (2005) that was adapted into an engineering design framework for water infrastructure (Mays, 2011). The methodology involves three technical stages: site assessment, hydrological design and evaluation, and design validation. Data collection techniques were carried out through observation, documentation, and interviews. Observations were made to complete the data needed in the study. Documentation was conducted to collect data related to zero runoff concept technology application. Interviews were conducted with the Head of the Hospital Facility Maintenance Installation to determine the application of the zero-runoff concept. The conclusion of this study is the result of the redesign using the zero-runoff concept by applying rainwater tanks, infiltration wells, bioretention, and permeable pavement, which theoretically can reduce runoff by 50.17%.

Abstract

Kota Bengkulu merupakan salah satu wilayah pesisir yang terletak pada jalur subduksi Sunda, sehingga memiliki potensi bahaya gempa bumi dan tsunami. Penelitian ini bertujuan memetakan tingkat bahaya tsunami dan zona keterpaparan spasial kawasan permukiman di Kota Bengkulu sebagai informasi dasar untuk mendukung mitigasi bencana berbasis spasial. Metode yang digunakan adalah pendekatan spasial-kuantitatif melalui analisis weighted overlay dengan mempertimbangkan empat parameter biofisik, yaitu ketinggian, kelerengan, jarak dari garis pantai, dan jarak dari sungai. Data utama diperoleh dari DEMNAS, peta garis pantai, jaringan sungai, jaringan jalan, serta data batimetri. Hasil analisis menunjukkan bahwa kawasan pesisir Kota Bengkulu memiliki konsentrasi kelas bahaya hingga sangat bahaya, terutama di sekitar Pantai Panjang, Kecamatan Ratu Agung, dan Kecamatan Ratu Samban. Sebaliknya, kawasan dengan tingkat bahaya relatif lebih rendah teridentifikasi di Kecamatan Sungai Serut dan Kecamatan Selebar. Analisis keterpaparan menunjukkan bahwa 22,22% luas kawasan permukiman berada pada kelas bahaya dan sangat bahaya, yang menunjukkan adanya konsentrasi keterpaparan spasial permukiman pada zona dengan tingkat bahaya relatif tinggi. Temuan tersebut memberikan informasi spasial mengenai lokasi permukiman yang perlu menjadi perhatian dalam pengendalian pemanfaatan ruang dan perencanaan mitigasi. Hasil pemetaan dapat digunakan sebagai informasi dasar untuk mendukung evaluasi tata ruang, penentuan kebutuhan kajian jalur dan fasilitas evakuasi, serta pengembangan strategi mitigasi kawasan pesisir, dengan penentuan intervensi teknis memerlukan analisis lanjutan mengenai aksesibilitas, kesesuaian penggunaan lahan, kapasitas evakuasi, dan kondisi sosial masyarakat.

Abstract

Desa Tolnaku, Kecamatan Fatuleu, Kabupaten Kupang, merupakan wilayah berbukit yang memerlukan informasi mengenai variasi respons seismik lokal sebagai bagian dari upaya pengurangan risiko bencana. Penelitian ini bertujuan mengkarakterisasi respons seismik lokal berdasarkan frekuensi dominan tanah dan mengestimasi Peak Ground Acceleration (PGA) berbasis data mikrotremor. Pengukuran mikrotremor dilakukan pada 45 titik dengan jarak antartitik sekitar 250 m. Data getaran tanah tiga komponen diproses menggunakan metode Horizontal-to Vertical Spectral Ratio (HVSR) pada perangkat lunak Geopsy untuk memperoleh frekuensi dominan (f0). Estimasi PGA dilakukan menggunakan pendekatan empiris Kanai dengan memanfaatkan periode dominan tanah serta parameter magnitudo, lokasi episenter, dan kedalaman gempa dari katalog gempa historis periode 1900–2014. Nilai f0 berkisar antara 0,125–17,407 Hz, sedangkan estimasi PGA berkisar antara 48,82–569,01 gal. Nilai PGA tertinggi diperoleh pada Titik 26 dengan f0 sebesar 17,407 Hz dan PGA 569,01 gal, sedangkan nilai terendah diperoleh pada Titik 8 dengan f0 sebesar 0,125 Hz dan PGA 48,82 gal. Variasi spasial frekuensi dominan dan PGA menunjukkan adanya heterogenitas respons situs di wilayah penelitian. Peta yang dihasilkan merupakan mikrozonasi seismik awal yang dapat digunakan sebagai informasi pendukung dalam kajian bahaya guncangan tanah dan perencanaan investigasi geologi maupun geoteknik lanjutan.

Abstract

Variations in filtration media and hydraulic retention time are important factors in optimizing wastewater quality improvement. The objective of this study is to recommend the optimal height level of gravel and silica sand (SiO2) combination and contact time in physical treatment methods for improving the quality of coffee processing wastewater. Three height-level variations of the gravel–silica sand filtration media combination were tested, namely 10:5 cm (T1), 7.5:7.5 cm (T2), and 5:10 cm (T3), along with two flow rate variations of 5.5 mL/second and 9.5 mL/second. All treatments were conducted in three replications to determine the standard error of the experimental data. The best-performing treatment was a combination of 5 cm gravel and 10 cm silica sand (T3) at a flow rate of 5.5 mL/second, which reduced turbidity, Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), ammonia (NH3), and phosphate (PO4) by 61.65±1.43%, 49.00±6.66%, 50.66±4.35%, 53.75±4.35%, and 76.99±4.54%, respectively, at a hydraulic retention time of 4 hours. The height level of the gravel and silica sand (SiO2) media, along with the optimum hydraulic retention time, had a positive effect on reducing pollutant content in coffee processing wastewater.

Abstract

Soil insects play an important role in maintaining the balance of the ecosystem in plantation areas, both as decomposers of organic matter and as biological control agents. Their presence can be an indicator of soil health and the stability of the agricultural environment. On the other hand, soil insects can be detrimental, namely as pests on plants. This study was conducted with the aim of inventorying the types of soil insects found in coffee plantations (Coffea sp.) Solok Radjo Cooperative, Solok Regency. Sampling was carried out from July to September 2025 using the pitfall trap method with a diagonal transect pattern of 100 meters. Identification of soil insects was carried out at the Integrated Pest Management Laboratory, Andalas University, Dharmasraya Campus. Identification based on morphological characteristics of soil insects with the help of a microscope and insect identification keys. The results based on research conducted in the Solok Radjo coffee plantation, Solok Regency, identified consist of 5 orders of soil insects, namely Coleoptera, Hymenoptera, Blattodea, Dermaptera, and Orthoptera. Also found 8 families of soil insects including Scarabaeidae, Carabidae, Formicidae, Ectobiidae, Blattidae, Anisolabididae, Gryllidae, and Gryllotalpidae.

Abstract

Environmental quality remains uneven across Indonesian provinces, while the effectiveness of subnational environmental expenditure is uncertain because it may depend on institutional conditions and cross-regional linkages. This study aims to assess how provincial environmental-function expenditure affects environmental quality in Indonesia while accounting for spatial dependence and the moderating roles of per capita income and regional democracy. This study examines a panel of 33 provinces from 2011 to 2019 using the STIRPAT framework and a dynamic spatial autoregressive (SAR) panel model with fixed effects. The conditional marginal effect of expenditure is jointly evaluated with its interactions with per capita income and democracy at the median values of both moderators. The combined conditional marginal effect is small and statistically insignificant for the environmental quality index (IKLH), air quality index (IKU), and water quality index (IKA). Within that combined effect, the baseline expenditure component is negative and significant for IKLH and IKU; the expenditure-democracy interaction is positive and significant; and the expenditure-income interaction is insignificant. Spatial dependence is detected for all three outcomes, but indirect expenditure effects are generally smaller than direct effects; a significant spillover appears mainly for short-run air quality. The results imply that larger budgets alone do not guarantee better environmental quality. Budget-use quality, democratic institutional capacity, and cross-regional coordination are essential for converting environmental expenditure into measurable outcomes.

Abstract

Pencemaran mikroplastik merupakan salah satu ancaman serius terhadap ekosistem perairan. Selain perairan, mikroplastik juga dapat mencemari sedimen di wilayah pesisir, salah satunya di Sungai Somber, Balikpapan. Tujuan penelitian ini adalah untuk menentukan jenis, kelimpahan, sebaran, dan tingkat pencemaran mikroplastik pada sedimen mangrove di sepanjang Sungai Somber, Kota Balikpapan. Sampel sedimen pada bagian permukaan (± 30 cm) diambil dari 10 stasiun (hulu-hilir) yang berbeda menggunakan sekop tangan, dan dianalisis menggunakan metode flotasi NaCl jenuh. Mikroplastik pada sedimen diidentifikasi dengan metode inspeksi visual mikroskopis. Ditemukan empat jenis mikroplastik pada sedimen, yaitu fragmen (1.733,33 partikel/kg), film (600,00 partikel/kg), fiber (6.166,67 partikel/kg), dan granul (233,33 partikel/kg). Kelimpahan mikroplastik pada sedimen berkisar 367 170 partikel/100 gr, dengan rata-rata 87,33 ± 46,74 partikel/100 gr, dan didominasi oleh fragmen (70%). Secara spasial, kelimpahan tidak menunjukkan pola linier yang konsisten dari hulu ke hilir; kelimpahan tertinggi ditemukan di bagian tengah (Stasiun 6 dan 7) yang berada di dekat aktivitas antropogenik, sedangkan di bagian hilir (Stasiun 8 10) kelimpahan cenderung lebih rendah. Analisis regresi linier menunjukkan hubungan yang lemah dan tidak signifikan secara statistik antara kelimpahan mikroplastik dan jarak dari hulu (r = 0,45; R² = 0,199; p > 0,05). Nilai Indeks Beban Pencemaran (PLI = 1,998) mengindikasikan tingkat risiko kontaminasi yang sangat rendah. Meskipun demikian, temuan ini menunjukkan perlunya pengelolaan limbah yang lebih terarah, khususnya di stasiun dengan kelimpahan relatif tinggi (Stasiun 6 dan 7), serta pemantauan berkala untuk mendukung kelestarian ekosistem Sungai Somber.

Abstract

Active involvement of all sectors of society is essential for effective waste management, particularly in addressing non biodegradable waste. Although the 3R (Reduce, Reuse, and Recycle) framework has been widely promoted and supported by the establishment of community-based waste banks to facilitate recycling activities, public participation in utilizing these facilities remains limited. This study aims to investigate the determinants of waste bank utilization intention by extending the Theory of Planned Behavior (TPB) with stimulus-based factors derived from the Stimulus Organism–Response (SOR) framework. Data were collected through a structured questionnaire survey involving 175 respondents. The variables examined include attitude, subjective norms, perceived behavioral control, environmental knowledge, and waste bank knowledge. Data analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results show that attitude, subjective norms, and perceived behavioral control have a significant positive effect on waste bank utilization intention, with attitude being the most influential determinant (β = 0.353). In addition, environmental knowledge (β = 0.426) and waste bank knowledge (β = 0.392) significantly influence attitudes toward waste bank utilization. The proposed model demonstrates moderate explanatory power, explaining 64.3% of the variance in waste bank utilization intention and 50.1% of the variance in attitude. Overall, these findings indicate that the extended TPB effectively explains waste bank utilization intention in the Pantai Indah Kapuk area, with knowledge serving as a key antecedent of attitude, which in turn contributes to waste bank utilization intention.
