Abstract

Indonesia memiliki batubara melimpah namun sebagian besar berperingkat rendah sehingga kurang effektif untuk digunakan sebagai bahan bakar. Telah dilakukan penelitian pemanfaatan batubara peringkat rendah jenis lignit sebagai bahan baku pembuatan karbon aktif, menggunakan metoda  aktivasi kimia ZnCl2 dengan variasi berat 5%-50%. Karbonisasi dilakukan  pada temperatur 500o C selama 1 jam di dalam reaktor pada kondisi tanpa oksigen, dengan mengalirkan gas nitrogen selama proses karbonisasi. Kondisi optimum dicapai pada komposisi aktivator ZnCl2 40 % dan batubara 60 % yang memiliki bilangan iodin 1.288,8 mg/g. Hasil penyerapan logam Cr menggunakan karbon aktif dari penelitian ini berkisar antara 55,5-60 % dengan konsentrasi awal  Cr 50-250 ppm, sedangkan untuk logam Fe menunjukkan hasil serapan 52% dengan konsentrasi awal 250 ppm dan untuk Cu meghasilkan serapan 39% pada konsentrasi awal 50 ppm.  Uji daya serap terhadap zat warna methilene blue menunjukkan hasil serapan yang sangat tinggi sebesar 97,4% pada konsentrasi awal 12,5 mmg, namun menunjukkan penurunan pada  konsentrasi awal methilene blue yang lebih tinggi. Secara umum, konsentrasi awal sangat berpengaruh pada tingkat adsorpsi logam dan zat warna. Makin tinggi konsentrasi awal, maka tingkat adsorpsi karbon aktif makin turun.

Abstract

In Indonesia, particularly in Semanan, tofu, and tempe are produced by home industries using traditional technology. However, the soybean processing industry is considered inefficient. The process used is considered not environmentally friendly. This Community Service activity aims to provide insight to the target audience regarding the integrated management of tofu-tempe wastewater. There are 3 stages in this activity. The first stage (1) is preparation. The second stage (2) is implementation. The third stage (3) is evaluation. The average amount of tofu/tempeh production in a day reaches 10-50 kg in Semanan, as well as the use of soybean raw materials on average ranging from 10-50 kg/day. As much as 53% of the people did not know the potential of tempe/tofu wastewater to be alternative energy for cooking, however, very high enthusiasm was shown by the analysis of the questionnaire with 100% of the people willing to become volunteers as a contribution to procuring waste processing technology that could produce alternative energy sources. This program has been followed up in the form of research on the Faculty's Excellence Research scheme, and this follow-up needs to be integrated.

Abstract

Groundwater in DKI Jakarta is subject to microbiological contamination. Approximately 32% of the population in DKI Jakarta relies on groundwater as an alternative source of clean water, highlighting the urgent need to address and prevent contamination. This study aims to investigate the effect of the separation distance between septic tanks and wells on the levels of Total coliform (TC), Escherichia coli (EC), and organic parameter contamination in shallow groundwater. Groundwater quality data, including TC, EC, and organic parameters from 265 monitoring points in DKI Jakarta, was obtained from the Jakarta Environment Agency in 2022. A quantitative descriptive approach, incorporating spatial mapping of bacterial and organic contamination using Geographic Information System (GIS) tools, was employed. MANOVA analysis using SPSS 26 was conducted to determine the relationship between septic tank distances and shallow water contamination levels. Results indicate that the separation distance between septic tanks and wells significantly influences TC and EC contamination in Jakarta Pusat, Jakarta Timur, and Jakarta Barat. Organic contamination, however, is significantly affected only in Jakarta Pusat and Jakarta Timur. In contrast, Jakarta Utara was identified as the most contaminated region, with 84% of groundwater samples showing TC contamination, 55% exhibiting Escherichia coli (EC) contamination, and 69% affected by organic pollution. However, these contaminations were not proven to be influenced by the proximity of septic tanks. This is likely due to the area's coastal location, where hydrogeological conditions and diverse pollution sources play a more significant role in groundwater contamination. Improvements in sanitation infrastructure could significantly enhance groundwater quality, particularly in highly vulnerable areas such as Jakarta Utara.

Abstract

Limbah cair kelapa sawit (LCKS) mengandung bahan organik dan padatan tersuspensi yang tinggi sehingga berbahaya jika dibuang ke lingkungan tanpa melalui proses pengolahan. Beberapa modifikasi unit pengolahan biologis terus dikembangkan untuk mengolah LCKS, antara lain unit rotating biological contactor (RBC). Penelitian bertujuan untuk mengidentifikasi pengaruh variasi kecepatan rotasi dan penggunaan bioball terhadap kinerja unit modifikasi RBC. Penelitian ini dilakukan dengan menggunakan unit RBC berskala laboratorium dengan variasi kecepatan rotasi sebesar 3, 5, dan 8 rpm. Hasil penelitian menunjukkan bahwa kecepatan rotasi secara signifikan memengaruhi kinerja sistem RBC. Penurunan kecepatan rotasi dari 8 rpm menjadi 3 rpm meningkatkan efisiensi penyisihan soluble chemical oxygen demand (SCOD) secara signifikan dari 62% menjadi 67,4% dan efisiensi total suspended solid (TSS) dari 66% menjadi 92,4%. Kecepatan rotasi rendah pada kandungan organik dan padatan tersuspensi yang tinggi akan memungkinkan lebih banyak waktu kontak antara LCKS dan mikroorganisme sehingga proses transfer oksigen menjadi lebih optimal untuk proses biodegradasi substrat. Walaupun efisiensi SCOD dan TSS mengalami peningkatan yang signifikan, nilai konsentrasi kedua parameter belum memenuhi baku mutu. Oleh karena itu, unit modifikasi RBC perlu diintegrasikan dengan unit pra-pengolahan seperti koagulasi-flokulasi atau media pertumbuhan attached growth tipe lain, seperti honeycomb untuk menghasilkan nilai konsentrasi efluen yang lebih optimum.

Abstract

The increase in the amount of groundwater withdrawal will inevitably pose a threat of seawater intrusion. The purpose of this research was to identify the distribution of shallow groundwater salinity in North Jakarta, West Jakarta and Central Jakarta and to develop a regional model of shallow groundwater salinity distribution. The data used in this study was that of the groundwater quality monitoring, obtained from the Regional Environment Status Book (SLHD), published by The Environment office of Greater Jakarta released in 2022, involving a total of 121 sample points in North Jakarta, West Jakarta, and Central Jakarta. The primary data was taken at 6 (six) sampling locations for model validation purposes. The study began with data grouping, using the Hierarchical Cluster Analysis (HCA) method. The results of identifying the highest distribution of salinity are in cluster 3 (three). A model was subsequently developed, after removing the outliers, with multiple linear analysis methods using the variable the distance from the coastline (X1), well depth (X2) and hardness (X3), to determine the influence of EC, TDS and salinity distribution in shallow groundwater. The results obtained are as follows; EC Models: YEC3 = -1.879+ (1.19.X1) + (5.08.X3). TDS models: YTDS3 = -2.211.30 + (0.81.X1) + (101.41.X2) + (4.07.X3). Salinity models: Ysalinity3 = -0.07+ (6.75×10-5.X1) + (2.4×10-4.X3). Model verification results for R2EC3 = 0.70; R2TDS3 = 0.92; R2salinity3 = 0.88. Validation results produce 21.14% for EC, 8.21% for TDS, and 22.87% for Salinity. This needs further research by increasing the number of primary samples.

Abstract

Di Indonesia, khususnya Kawasan Semanan, tahu dan tempe diproduksi oleh industri rumah tangga dengan menggunakan teknologi tradisional. Namun, industri pengolahan kedelai ini dinilai tidak efisien, tidak hanya ada pengurangan produktivitas, tetapi proses yang digunakan dianggap tidak ramah lingkungan. Tujuan dari kegiatan Pengabdian kepada Masyarakat ini adalah untuk memberikan wawasan kepada khalayak sasaran terkait dengan pengelolaan air limbah tahu-tempe yang terpadu. Pelaksanaan kegiatan ini terdiri dari 3 (tiga) tahapan. Tahap pertama (1) yaitu persiapan, meliputi survey lokasi, koordinasi dengan pihak mitra, dan pemetaan wilayah produksi tempe-tahu. Tahap kedua (2) yaitu pelaksanaan, meliputi kegiatan penyuluhan, pengisian kuesioner, dan diskusi internaktif. Tahap ketiga (3) yaitu evaluasi, terakit hasil penyuluhan, analisis data kuesioner, dan rencana tindak lanjut. Rata-rata jumlah produksi tahu/tempe dalam sehari mencapai 10-50 kg di Kelurahan Semanan, begitu juga halnya dengan penggunaan bahan baku kedelai rata-rata berkisar antara 10-50 kg/hari. Sebanyak 53% masyarakat belum mengetahui potensi limbah cair tempe/tahu menjadi alternatif energi untuk memasak, namun antusiasme yang sangat tinggi ditunjukkan dengan analisis kuesioner dengan angka 100% masyarakat bersedia untuk menjadi volunter sebagai kontribusi pengadaan teknologi pengolah limbah yang dapat menghasilkan sumber energi alternatif. Program ini telah ditindaklanjuti dalam bentuk penelitian skema Penelitian Unggulan Fakultas, dan tindak lanjut ini perlu dikembangkan secara terintegrasi.
