Abstract

Salah satu industri yang memiliki risiko tinggi adalah sektor pertambangan. Berdasarkan data Minerba One Data Indonesia Kementerian ESDM dalam 3 tahun terakhir 2022-2024) menunjukan terdapat 679 kasus kecelakaan kerja dengan jumlah kematian 132 kasus sisanya 547 dengan kasus ringan hingga berat. Kabupaten Bojonegoro merupakan wilayah penghasil minyak mentah di Provinsi Jawa Timur. Di kawasan desa Kedewan, 30 kilometer dari kabupaten Bojonegoro, sedikitnya hingga saat ini tersisa 40%  sumur minyak produksi dari 700 titik sumur yang di masa lalu menjadi kekuasaan kolonial sumur-sumur itu tersebar di desa Wonocolo dan Hargomulyo, dengan permasalahan tersebut peneliti tertarik untuk mengetahui potensi bahaya dan menganalisis risiko kerja yang kemungkinan besar terdapat pada area pertambangan minyak tradisional wonocolo khususnya pada pengolahannya dengan pendekatan HIRARC (Hazard Identification, Risk Assessment, and Risk Control) karena belum ada penelitian yang dilakukan pada pertambangan minyak tradisional Wonocolo, dan kebanyakan tambang tradisional sering beroperasi tanpa adanya pengawasan dari pihak terkait. Hasil menunjukkan bahwa analisis resiko yang terjadi meliputi fisik, kimia, ergonomi dan psikologis. Pada penilaian risiko terdapat kategori low sebanyak 3 kegiatan yaitu terluka akibat benda tajam, tertimpa yang menyebabkan terluka, tertimpa benda berat. Penilaian risiko tingkat medium ada 3 kegiatan yaitu terkilir, tertekan, stress. Terakhir penilaian risiko tingkat high ada 4 yaitu terbakar, terpeleset dan jatuh, terpapar asap beracun, dan terpapar uap minyak. Pengendalian risiko dilakukan dengan tindakan rekayasa dan administratif, seperti penimbunan tanah yang licin, penggunaan Alat Pelindung Diri (APD), dan pemasangan spanduk atau poster yang mengingatkan pekerja untuk beristirahat  yang cukup dan menggunakan APD

Abstract

Tekstur tanah merupakan komponen penting dalam menentukan kesesuaian lahan untuk kegiatan pertanian. Penelitian ini bertujuan untuk menganalisis tekstur tanah di beberapa titik sampel di Desa Kawengan, Kecamatan Kedewan, Kabupaten Bojonegoro, serta mengevaluasi kesesuaiannya terhadap komoditas pertanian utama di daerah tersebut. Metode yang digunakan meliputi pengambilan sampel tanah di tiga lokasi berbeda, analisis laboratorium untuk menentukan persentase fraksi pasir, debu, dan liat, serta klasifikasi tekstur menggunakan segitiga tekstur USDA. Hasil analisis menunjukkan bahwa tekstur tanah di lokasi penelitian berkisar antara lempung berpasir hingga lempung, yang memiliki pengaruh terhadap kemampuan tanah dalam menyimpan air dan unsur hara. Berdasarkan hasil evaluasi, sebagian besar lahan tergolong sesuai (S2) hingga sesuai marginal (S3) untuk komoditas pertanian seperti jagung dan kedelai. Penelitian ini memberikan dasar ilmiah bagi perencanaan tata guna lahan pertanian yang lebih berkelanjutan di wilayah tersebut.

Abstract

The Bengawan Solo River is a primary water resource in Central and East Java. Human activities along the Watershed (DAS) have affected water quality. This study evaluates the water quality of the Bengawan Solo River during the dry and rainy seasons from 2019 to 2023 using the Pollution Index (IP) method, based on secondary data from Perum Jasa Tirta I at four locations: upstream, middle, downstream 1, and downstream 2. The analyzed parameters include physical (temperature, TDS, TSS), chemical (pH, DO, BOD, nitrate), and biological (Total coliform) aspects. The results indicate that pH, TDS, and nitrate remain within quality standards, whereas temperature, BOD, DO, and TSS often exceed the limits, especially during the rainy season. The Pollution Index (Pij) suggests better water quality in the dry season, predominantly classified as "Lightly Polluted." However, in the 2021 rainy season, two locations reached the "Moderately Polluted" category, indicating that rainfall contributes to increased pollution.

Abstract

This study aims to evaluate the effectiveness of Reverse Osmosis (RO) membranes in reducing Total Dissolved Solids (TDS) in wastewater treatment in the oil and gas industry. High levels of TDS in industrial wastewater can affect equipment performance and does not meet water quality standards. The study used a descriptive quantitative approach with observation, interviews, literature studies, and company data analysis methods. The RO system implemented included pretreatment, chemical injection, high-pressure filtration, and storage of treated water. The results showed a significant decrease in TDS from 1,200 mg/L to 150 mg/L (efficiency 87.5%), turbidity from 3.2 NTU to 0.8 NTU (75%), and total hardness from 450 mg/L to 80 mg/L (82.2%), while pH was stable in the range of 6.8–7.1. These results prove that RO technology is capable of producing water with quality that meets the quality standards of the Minister of Health Regulation No. 492 of 2010. This study confirms the superiority of RO as an effective industrial water treatment method and recommends further research on operational costs, energy efficiency, and fouling control for long-term optimization.

Abstract

The problem of household organic waste remains an environmental issue that requires effective management in various regions, including Jelu Village. This community service activity aims to increase active community participation in organic waste management through the use of Black Soldier Fly (BSF) larvae. BSF cultivation technology was chosen because it can quickly decompose organic waste and produce by-products in the form of animal feed and organic fertilizer. This program was implemented through an educational approach, technical training, and direct mentoring for residents from several neighborhood units (RT) in Jelu Village. The results of the activity showed an increase in community knowledge and skills in BSF cultivation, with maggot production reaching 2 kg in three weeks and daily organic waste management of around 4–5 kg. Furthermore, the community was also able to independently build cultivation cages. This activity has succeeded in raising ecological awareness while providing economic benefits, and is expected to become a model for sustainable organic waste management at the village level.

Abstract

Traditional petroleum mining activities in 137 old wells in Wonocolo Village, Bojonegoro Regency Council District, East Java, have a positive impact on the local community's economy, but also have a negative impact on the environment in the form of pollution of surface water. The study aims to determine the quality of the Bongso River in the traditional Wonocolo petroleum mining area based on physical and chemical parameters (temperature, pH, DO, TSS, TDS, COD, phenol, and nitrate), as well as analyze the level of pollution in the river using the Pollution Index method. The results of the Bongso River water quality analysis contained parameters that exceeded quality standards, namely, SB 1 station with COD levels of 47.1 mg / L and Phenol 0.196 mg / L. SB 2 station with TDS levels of 1010 mg / L, TSS 93.60 mg / L, COD 94.0 mg / L and phenol 0.552 mg / L. SB 3 station TDS levels 1190 mg / L, TSS 1778 mg/L, COD 84.7 mg/L, and phenol 0.747. Station SB 4 levels TDS worth 1450 mg / L, TSS 1019 mg / L, COD 28.2 mg / L, phenol 0.632 mg / L and DO levels do not meet the minimum quality standards of 3.4 mg / L. Station SB 5 levels TDS 1310 mg / L, COD 103.5 mg / L and phenol 0.364 mg / L. Station SB 6 levels TDS 1400 mg / L, COD 65.9 mg/L and phenol 0.585 mg/L. Station SB 7 levels TDS 1230 mg/L, TSS 54.80 mg/L and phenol 0.556 mg/L. Salinity of the Bongso River increased from upstream (SB1) to middle (SB2); 0 ppt to 4 ppt (rainy season). Water quality status using the IP method shows that SB 1 and SB 5 stations are categorized as Lightly Polluted. Meanwhile, SB 2, SB 3, SB 4, SB 6, and SB 7 stations are categorized as Moderately Polluted.

Abstract

Wonocolo Village in Bojonegoro Regency is one of the traditional oil mining areas that still contains old Dutch oil wells. The presence of these wells has the potential to affect groundwater quality. Petroleum that contaminates the soil can seep into groundwater, posing a serious threat to areas that rely on it as a source of clean water. This study aims to evaluate groundwater parameters, including temperature, pH, cadmium, and sulfate, by the standards set by the Indonesian Ministry of Health Regulation No. 32 of 2017, specifically regarding hygiene, sanitation, and public baths. Sampling was conducted using a purposive sampling method at 14 points. Data analysis was performed using the inverse distance weighted (IDW) interpolation method. The results showed that in the densely populated southern part of the study area, the temperature at sampling point SG 13 reached 35°C, and cadmium levels across all samples ranged from 0.059 to 0.156 mg/L, exceeding the permitted quality standards. In contrast, pH and sulfate values met the quality standards set by Permenkes No. 32 of 2017. Therefore, efforts are necessary to reduce cadmium levels in the groundwater of Wonocolo Village, Bojonegoro Regency.
