Abstract

The use of Black Soldiet Fly (BSF) in processing organic waste offers numerous benefits, including significant waste volume reduction, transformation of waste into value-added products such as organic fertilizers, livestock feed, and fish feed, as well as supporting the implementation of a circular economy. However, organic waste processing practices in BSF larvae or what is more widely known as maggot with maggot houses often face challenges, particularly in terms of funding. Financial factors are crucial elements that determine the operational sustainability of such waste management systems. This study aims to analyze the financial conditions and operational feasibility of Rumah Maggot Cimincrang and Imah Maggot Bantaran. The study employs the Net Present Value (NPV) method, which calculates the present value of total net revenues after deducting costs over a specific period. NPV serves as a tool to assess the financial feasibility of an activity. If the NPV is positive, the activity is considered financially feasible and profitable. The results indicate that the operational feasibility of Rumah Maggot Cimincrang can be achieved through product diversification, such as producing maggot meal and maggot oil, alongside optimizing marketing efforts via digital platforms like e-commerce with a NPV of IDR 161,769,698. Meanwhile, Imah Maggot Bantaran, which operates on a community-based model, is already financially viable with an NPV of IDR 4,333,190,208. However, further efforts are needed to enhance operational consistency, ensuring the production of sustainable products over the long term.

Abstract

Obi Island in North Maluku Province, Indonesia, has undergone significant land cover changes due to the expansion of nickel mining activities, especially since official operations began in 2010; the conversion of built-up land and vegetated areas into mining and settlement zones has increased pressure on land carrying capacity and contributed to more frequent flooding during the rainy season. This study uses spatial analysis based on Landsat 5 (1995) and Landsat 8 OLI (2025) satellite imagery to map land cover changes over three decades. The results show an increase in built-up land area from 448.84 hectares to 698.67 hectares, as well as the emergence of a 4,963.67-hectare mining area in 2025, while open land, water bodies, and vegetation have significantly declined. These findings demonstrate the direct impact of mining activities on landscape dynamics and the local environment, necessitating sustainable management and mitigation measures to maintain ecological balance and reduce the risk of related disasters.Keywords: LULC, Nickel Mining, Obi island

Abstract

ABSTRAK Limbah cair laundry menjadi salah satu masalah pencemaran lingkungan karena mengandung deterjen, fosfat, surfaktan, dan bahan kimia lain yang berpotensi menurunkan kualitas perairan. Aktivitas ini dilakukan setiap hari sehingga membutuhkan pengolahan secara tepat agar dapat mengurangi beban pencemar di badan air. Salah satu pengolahan limbah cair laundry adalah dengan metode koagulasi-flokulasi menggunakan koagulan aluminium sulfat dan flokulan poliakrilamida. Tujuan penelitian ini adalah untuk mengetahui pengaruh variasi flokulan poliakrilamida dan menentukan dosis optimum flokulan terhadap persentase penyisihan kontaminan pada limbah cair laundry. Proses koagulasi-flokulasi limbah cair laundry dilakukan menggunakan metode jar test pada 1000 mL air limbah dengan pengadukan cepat 120 rpm selama 10 menit dan pengadukan lambat 30 rpm selama 20 menit. Dosis koagulan aluminium sulfat yang digunakan sebesar 4 g/L dan variasi dosis flokulan poliakrilamida yang digunakan 0.1, 0.2, 0.3, 0.4, 0.5, dan 0.6 g/L. Penambahan flokulan poliakrilamida tidak berpengaruh pada perubahan pH karena penurunan pH lebih dipengaruhi oleh penambahan koagulan aluminium sulfat. Persentase penyisihan tertinggi pada parameter TSS, COD, fosfat, dan MBAS diperoleh dengan dosis optimum flokulan sebesar 0.6 g/Ldengan masing-masing persentase penyisihan sebesar 96.52%, 45.65%, -37.23%, dan 88.36%. Kata kunci: Aluminium sulfat, flokulan, limbah cair laundry, poliakrilamida ABSTRACT Laundry wastewater is one of the environmental pollution problems because it contains detergents, phosphates, surfactants, and other chemicals that have the potential to reduce water quality. This activity is carried out every day so it requires proper processing to reduce the pollutant load in water bodies. One of the laundry wastewater treatment methods is the coagulation-flocculation method using aluminum sulfate coagulant and polyacrylamide flocculant. The purpose of this study was to determine the effect of variations in polyacrylamide flocculants and determine the optimum flocculant dosage on the percentage of contaminant removal in laundry wastewater. The coagulation-flocculation process of laundry wastewater was carried out using the jar test method on 1000 mL of wastewater with fast stirring at 120 rpm for 10 minutes and slow stirring at 30 rpm for 20 minutes. The aluminum sulfate coagulant dosage used was 4 g/L and the polyacrylamide flocculant dosage variations used were 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6 g/L. The addition of polyacrylamide flocculant did not affect the pH change because the decrease in pH was more influenced by the addition of aluminum sulfate coagulant. The highest removal percentages for TSS, COD, phosphate, and MBAS parameters were obtained with an optimum flocculant dose of 0.6 g/L with removal percentages of 96.52%, 45.65%, -37.23%, and 88.36%. Keywords: Aluminum sulfate, flocculant, laundry waste, polyacrylamide

Abstract

ABSTRAK  Kawasan industri merupakan penyumbang polusi udara terbesar, salah satu kawasan industri yang berdiri berdampingan dengan kawasan pertanian ialah Padang Industrial Park (PIP). Penelitian ini bertujuan untuk menganalisis sebaran polusi udara yang ada di Padang Industrial Park (PIP), menggunakan metode Dustfall Canister serta metode analisis yang digunakan ialah Gravimetri untuk mendapatkan konsentrasi dari debu jatuh. Selanjutnya dilakukan analisis lanjutan dari pengaruh debu jatuh pada kesehatan tanaman dengan menggunakan nilai Air Pollution Tolerance Index (APTI) untuk menuntukan toleransi tanaman terhadap polusi udara. Hasil yang diperoleh dari 9 titik sampel yang terdiri dari komoditi jagung dan padi, didapatkan nilai APTInya berada pada kategori sensitif. Hal ini menandakan komoditi jagung dan padi yang hidup di sekitar kawasan Padang Industrial Park (PIP) memiliki toleransi yang rendah terhadap polusi udara. Selanjutnya, konsentrasi tertinggi debu jatuh yang didapatkan selama 14 hari berada pada titik sampel 2 berjumlah 7,3516 ton/km2/bulan, nilai ini tidak melebihi standar baku mutu yang diperuntukan pada kawasan pemukiman. Sehingga, kualitas udara yang berada di kawasan industri Padang Industrial Park (PIP) termasuk pada kategori baik, namun perlu dilakukan pemantauan secara berkala. Kata kunci: APTI, debu jatuh, gravimetri, jagung, padi ABSTRACT Industrial areas are the largest contributors to air pollution, one of the industrial areas that stands side by side with agricultural areas is Padang Industrial Park (PIP). This study aims to analyze the distribution of air pollution in Padang Industrial Park (PIP), using the Dustfall Canister method and the analysis method used is Gravimetry to obtain the concentration of falling dust. Furthermore, further analysis was carried out on the effect of falling dust on plant health using the Air Pollution Tolerance Index (APTI) value to determine plant tolerance to air pollution. The results obtained from 9 sample points consisting of corn and rice commodities, the APTI value was found to be in the sensitive category. This indicates that corn and rice commodities that grow around the Padang Industrial Park (PIP) area have a low tolerance to air pollution. Furthermore, the highest concentration of falling dust obtained for 14 days was at sample point 2 amounting to 7.3516 tons/km2/month, this value does not exceed the quality standards intended for residential areas. Thus, the air quality in the Padang Industrial Park (PIP) industrial area is included in the good category, but regular monitoring is necessary. Keywords:  APTI, corn, dustfall, gravimetri, rice

Abstract

ABSTRAK  Industri semen menghasilkan air limbah dengan kandungan TSS tinggi yang memerlukan sistem pengendalian sedimen efektif. Penelitian ini menganalisis debit limpasan, mengevaluasi kesesuaian desain settling pond terhadap SNI 6774-2008, menguji hubungan statistik variabel hidrometeorologi, dan merumuskan rekomendasi teknis pada PT X (catchment area 199.3 ha). Pengambilan sampel selama 20 hari (November 2024) mengukur TSS inlet–outlet, intensitas hujan, dan debit limpasan. Hujan rencana 85.34 mm/hari dengan intensitas 31.14 mm/jam dan koefisien limpasan 0.9 menghasilkan debit 0.07392 m³/s. Evaluasi menunjukkan waktu detensi 47,3 menit (standar 1,5–3 jam), beban permukaan 3.7 m/jam (standar 0.8–2.5 m/jam), dan bilangan Reynolds 40,645 (standar <2,000), mengindikasikan desain belum optimal meskipun kolam beroperasi. Korelasi Pearson menunjukkan hubungan negatif signifikan antara efisiensi TSS dan intensitas hujan (r = -0.641; p = 0.002), dengan efisiensi rata-rata 72.71% dan hanya 25% hari memenuhi baku mutu outlet ≤30 mg/L. Rekomendasi meliputi pemasangan pintu air vertikal adjustable, pengerukan sludge berkala, dan revegetasi buffer zone untuk menekan beban sedimen inlet. Implementasi meningkatkan kepatuhan SNI 6774-2008 dan mendukung pengelolaan limbah industri semen berkelanjutan. Kata kunci: Analisis Hidrolik; Evaluasi desain SNI 6774 – 2008; Pengendalian sedimen; Settling Pond;  ABSTRACT  The cement industry generates wastewater with high Total Suspended Solids (TSS) concentrations requiring effective sediment control systems. This study analyzed runoff discharge, evaluated settling pond design compliance with SNI 6774-2008, examined statistical relationships among hydrometeorological variables, and formulated technical recommendations at PT X (199.3 ha catchment area). Sampling over 20 consecutive days (November 2024) measured inlet–outlet TSS, rainfall intensity, and runoff discharge. A design rainfall of 85.34 mm/day with an intensity of 31.14 mm/hour and runoff coefficient of 0.9 produced a discharge of 0.07392 m³/s. Evaluation results showed detention time of 47.3 minutes (standard 1.5–3 hours), surface loading rate of 3.7 m/hour (standard 0.8–2.5 m/hour), and Reynolds number of 40,645 (standard <2,000), indicating suboptimal hydraulic performance despite operational functionality. Pearson correlation revealed a significant negative relationship between TSS removal efficiency and rainfall intensity (r = -0.641; p = 0.002), with an average efficiency of 72.71% and only 25% of observation days meeting the outlet standard ≤30 mg/L. Recommended improvements include installation of adjustable vertical weir gates, periodic sludge dredging, and buffer zone revegetation to reduce sediment inflow. Implementation is expected to enhance compliance with SNI 6774-2008 and support sustainable wastewater management in the cement industry. Keywords: Hydraulic analysis; SNI 6774-2008 design evaluation; Sediment Control; Settling Pond
