Abstract

Artisanal and small-scale gold mining (ASGM) can increase the levels of heavy metals in surface water and groundwater sources. This study was conducted to evaluate water quality in Pohuwato Regency, Gorontalo, Indonesia. Sampling was performed at three sites: a reservoir, an irrigation channel, and a well. The concentrations of lead (Pb), cadmium (Cd), iron (Fe), manganese (Mn), and mercury (Hg) were analyzed using Atomic Absorption Spectrophotometry (AAS). The results indicated that Hg concentrations ranged from 0.00883 to 0.01493 mg/L (≈8.8–14.9× above the WHO guideline value of 0.001 mg/L), Mn concentrations ranged from 0.1309 to 0.543 mg/L (≈1.3–5.4× above the WHO guideline value of 0.1 mg/L), while Pb concentrations ranged from 0.0019 to 0.0048 mg/L, Cd concentrations ranged from 0.0002 to 0.0006 mg/L, and Fe concentrations ranged from 0.0728 to 0.101 mg/L, all of which were below the recommended threshold values for drinking water. The findings emphasize the importance of mitigation strategies based on mining governance, strengthening water safety plans, as well as interventions for household water treatment (adsorption/filtration) and risk communication.

Abstract

ABSTRAK Transformasi penggunaan lahan di Daerah Aliran Sungai (DAS) Limboto merupakan indikator kritis tekanan antropogenik terhadap ekosistem Danau Limboto yang kini berstatus Kritis Nasional. Sebagian besar kajian sebelumnya mengevaluasi perubahan ini menggunakan metode deskriptif persentase tanpa validasi statistik inferensial, sehingga gagal mendeteksi signifikansi anomali data dalam distribusi spasial. Penelitian ini bertujuan untuk: (1) menganalisis karakteristik distribusi data perubahan lahan DAS Limboto 2018-2022, (2) menguji signifikansi perbedaan struktur penggunaan lahan menggunakan pendekatan statistika non-parametrik, dan (3) mengevaluasi dampak lingkungan dari dinamika tersebut terhadap fungsi hidrologis DAS. Data penelitian adalah data sekunder luas tutupan lahan time series (n=12 kategori). Analisis dilakukan melalui Uji Normalitas Shapiro-Wilk dan Uji Beda Dua Sampel Berpasangan Wilcoxon Signed-Rank. Hasil: Analisis deskriptif menunjukkan degradasi masif pada Semak Belukar (-9.838,89 Ha atau -79,16%) yang beralih fungsi menjadi Pertanian Lahan Kering (+4.854,16 Ha) dan Hutan Tanaman (+1.270 Ha). Uji statistik menunjukkan distribusi selisih perubahan lahan tidak normal (p<0.05). Uji Wilcoxon menghasilkan nilai signifikansi asimtotik (p) sebesar 0.248 (p>0.05), yang berarti secara statistik agregat tidak terdapat perbedaan signifikan pada median luas lahan. Temuan ini mengindikasikan fenomena "stabilitas statistik semu" (statistical illusion of stability), di mana keseimbangan peringkat data menutupi realitas degradasi lingkungan. Konversi lahan vegetasi alami menjadi pertanian jagung monokultur di area hulu diprediksi meningkatkan koefisien larian (run-off) dan memperparah laju sedimentasi ke Danau Limboto.

Abstract

Penelitian ini menganalisis dinamika perubahan tata ruang antara lahan pertanian (sawah) dan lahan bukan pertanian di Provinsi Gorontalo periode 2017–2023 serta implikasinya terhadap ketahanan pangan daerah. Data yang digunakan berupa deret waktu sekunder luas lahan sawah dan luas lahan bukan pertanian yang dihimpun dari statistik resmi Provinsi Gorontalo. Data dianalisis secara deskriptif dan deret waktu sederhana melalui perhitungan perubahan persentase, rata-rata perubahan tahunan, tren linier, serta korelasi Pearson. Hasil penelitian menunjukkan bahwa luas lahan sawah menyusut dari 34.764 ha pada 2017 menjadi 30.112 ha pada 2023, atau turun 13,38% (sekitar 4.652 ha) dengan rata-rata kehilangan 775 ha per tahun. Sebaliknya, lahan bukan pertanian meningkat dari 283.890 ha menjadi 307.873 ha (naik 8,45% atau 23.983 ha) dengan penambahan rata-rata 3.997 ha per tahun. Rasio luas lahan bukan pertanian terhadap sawah yang sekitar delapan kali pada 2017 meningkat menjadi lebih dari sepuluh kali pada 2023. Korelasi Pearson antara kedua seri sebesar –0,31 menunjukkan hubungan negatif sedang, yang mengindikasikan bahwa ekspansi lahan non-pertanian sebagian terjadi melalui konversi lahan sawah. Dengan asumsi produktivitas padi sawah 4,4–5,6 ton/ha, hilangnya 4.652 ha sawah berpotensi menurunkan produksi padi tahunan sekitar 20–26 ribu ton, setara ±8–10% produksi padi Gorontalo tahun 2023. Tren ini dapat melemahkan dimensi ketersediaan (availability) pangan, kecuali diimbangi oleh peningkatan produktivitas, perbaikan infrastruktur irigasi, serta perlindungan ketat terhadap Kawasan/Lahan Pertanian Pangan Berkelanjutan (KP2B/LP2B). Penelitian merekomendasikan penguatan penataan ruang, penegakan zona lindung lahan pangan, dan integrasi indikator ketahanan pangan dalam kebijakan pembangunan daerah.

Abstract

Rock mining plays an important role in supporting regional infrastructure development in Bone Bolango Regency, Gorontalo Province. However, quarry expansion also poses environmental risks that require proper management and supervision. This study evaluates the implementation of environmental management at three active rock mining sites. A mixed-methods approach was applied, integrating field observations, interviews, document analysis, and ambient air quality monitoring to assess compliance with UKL-UPL requirements. The results indicate that environmental management implementation remains inadequate. Major issues include weak erosion and sediment control, limited dust suppression, insufficient waste management, and inconsistent environmental monitoring, despite the availability of formal management documents. Air quality measurements at AF-01, AF-02, and AF-03 show spatial variation in particulate concentrations, influenced by mining intensity and local climatic conditions. Although all values are below national ambient air quality standards, field observations reveal localized dust accumulation, indicating insufficient on-site mitigation. Governance challenges further constrain the application of Good Mining Practices, including limited enforcement capacity, the absence of certified KTT/PJO personnel, and weak inter-institutional coordination. Local communities also reported disturbances related to dust, noise, and truck traffic. Overall, the study emphasizes the need for stronger regulatory oversight, improved technical capacity, and participatory monitoring to support adaptive and sustainable mining management.

Abstract

This study aims to analyze the effect of per capita income on poverty levels in Bone Bolango Regency, Gorontalo Province. The regency faces challenges in reducing poverty despite various government programs. The knowledge gap regarding the direct contribution of per capita income to poverty is the focus of this research. Here, we demonstrate that an increase in per capita income has a negative correlation with poverty levels, where each rise in income is associated with a significant reduction in poverty percentage. However, the study also found that population growth significantly increases poverty if not accompanied by improvements in economic and social infrastructure. The findings of this research imply that economic policies aimed at increasing income must be supported by improvements in access to education, healthcare, and infrastructure to more effectively reduce poverty rates in the region. Future research is expected to deepen the analysis of other factors that influence poverty more comprehensively

Abstract

Watershed degradation contributes to increased peak discharge, erosion, and sedimentation in downstream areas. Forest and Land Rehabilitation (FLR) has become an important approach for restoring hydrological functions through increasing vegetation cover and controlling surface runoff. This study aimed to analyze the predicted impacts of FLR on peak discharge, erosion, and sedimentation in the Piloliyanga micro-catchment, Modelomo Watershed. The study employed a quantitative descriptive approach based on Geographic Information Systems (GIS), hydrological analysis, and land cover change simulation. Erosion analysis was conducted using the Universal Soil Loss Equation (USLE), while sedimentation was estimated using the Sediment Delivery Ratio (SDR) approach. The results showed that FLR has the potential to reduce peak discharge, erosion, and sedimentation through increased infiltration and vegetation interception. The novelty of this study lies in the integration of USLE, SDR, and land cover change simulation within a tropical micro-catchment watershed scale. The findings imply that watershed-based vegetative rehabilitation can improve hydrological stability and support land degradation control in the upstream area of the Modelomo Watershed.

Abstract

The model for estimating groundwater availability for plants often overlooks the type of soil and the capacity of plants to absorb water from it. This study employs laboratory soil tests and statistical analyses to examine the relationship between various soil types in Pohuwato Regency and the variations in Groundwater Availability (KAT) levels for rice and corn plants. The results indicate that Andosol and Litosol are the soil types with the highest Field Capacity values in Pohuwato Regency, ranging from 331 mm to 403 mm. Meanwhile, Alluvial and Regosol soil types exhibit the lowest Permanent Wilting Point values in the Pohuwato Regency, ranging from 23 mm to 53 mm. The study results revealed a very high average correlation value of 0.907 between Field Capacity and the Permanent Wilting Point concerning the Groundwater Availability model. The research data, which includes soil characteristics and the Groundwater Availability model for rice and corn cultivation in Pohuwato Regency, can serve as a foundation for strategies that farmers can employ to enhance their future agricultural productivity.
