Abstract

ABSTRAKGedung asrama Institut Teknologi Sumatera (ITERA) memanfaatkan air tanah dalam memenuhi kebutuhan air bersih penghuninya, namun kuantitas air tanah pada asrama TB 4 ini tidak cukup untuk memenuhi kebutuhan air bersih, sehingga dibutuhkan transfer air dari asrama lain. Untuk itu diterapkan Pemanenan Air Hujan (PAH) sebagai alternatif penyediaan air bersih dan sebagai upaya dalam memanfaatkan air hujan. Air hujan yang dapat ditampung dipengaruhi oleh curah hujan harian maksimum menggunakan analisis hidrologi. Metode analisis hidrologi ini bertujuan untuk menganalisis kuantitas air hujan yang dapat tertampung melalui atap Asrama TB 4 ITERA. Data curah hujan yang dipakai pada perencanaan ini yaitu data dari BMKG Radin Inten Lampung Selatan. Untuk mendapatkan curah hujan dihitung menggunakan distribusi terpilih yaitu log pearson tipe III dan intensitas hujan menggunakan metode mononobe dengan PUH 5 tahun selama 2 jam sebesar 24.78 mm.hari-1. Dari curah hujan tersebut didapatkan dimensi talang, pipa tegak, pipa datar, dan pipa pencucian atap berukuran 5 inci. Sedangkan volume air hujan yang dapat tertampung sebanyak 10.100 liter per harinya. Perencanaan pemanenan air hujan di asrama TB 4 ITERA ini memerlukan biaya sebesar Rp. 65,532,800.00.Kata kunci: air hujan, asrama, curah hujan, hidrologiABSTRACTThe dormitory building of the Sumatra Institute of Technology (ITERA) utilizes ground water to meet the clean water needs of its residents, but the quantity of ground water in the TB 4 hostel is not sufficient to meet clean water needs, so water transfers from other dormitories are needed. For this reason, Rainwater Harvesting (PAH) is applied as an alternative to providing clean water and as an effort to utilize rainwater. The rainwater that can be collected is influenced by the maximum daily rainfall using hydrological analysis. This hydrological analysis method aims to analyze the quantity of rainwater that can be accommodated through the roof of the TB 4 ITERA Dormitory. Rainfall data used in this plan is data from BMKG Radin Inten South Lampung. To get the rainfall calculated using the selected distribution, namely log Pearson type III and rain intensity using the mononobe method with PUH 5 years for 2 hours at 24.78 mm.day-1. From the rainfall, the dimensions of the gutter, standpipe, flat pipe, and roof washing pipe are 5 inches in size. Meanwhile, the volume of rain water that can be accommodated is 10,100 liters per day. Rainwater harvesting planning at the TB 4 ITERA hostel requires a fee of Rp. 65,532,800.00.Keywords: rainwater, boarding house, rainfall, hydrology

Abstract

Rapid mixing time is one of the most important factors on coagulation – flocculation process in water treatment. In this study, Moringa Oleifera (MO) seed was used as a natural coagulant to remove Fe and Mn in well water. The effects of rapid mixing time to remove Fe, Mn, and turbidity floc size were investigated. Here, rapid mixing time variations were used around 30 -300 s coagulant doses (equal 33 mg/l) with 100 rpm rapid mixing speed while slow mixing speed of 40 rpm for 10 minutes and settling time for 60 minutes. The result showed that Fe and Mn removal ranging from 26-48 % and 13-31% with optimum rapid mixing time to remove Fe was 180 s; Mn was 150 s; and turbidity was 180 s, respectively. Based on correlation analysis using SPSS software with the Rank Spearman method, the residual concentration of Fe had a very strong correlation with residual Mn (r = 0.967) and a strong correlation with turbidity (r = 0.746) while the residual concentration of Mn has a very strong correlation with turbidity (r = 0.809).

Abstract

Sungai Way Jelai adalah salah satu sungai penting yang dimanfaatkan untuk mengairi sawah di Kabupaten Tanggamus, Lampung. Daerah sepanjang bantaran sungai juga dimanfaatkan bagi kegiatan pertanian dan pemukiman yang berpotensi mempengaruhi kualitas air. Penelitian ini dilakukan guna mengetahui status mutu air serta menganalisa daya tampung beban pencemaran di Sungai Way Jelai. Parameter kualitas air yang diuji adalah TDS, pH, DO, BOD dan Amonia (NH3-N). Sampel diambil pada tiga titik: hulu, tengah, dan hilir sungai. Metoda Neraca Massa digunakan untuk menghitung daya tampung beban pencemaran air Sungai Way Jelai dan dievaluasi menggunakan baku mutu air kelas 1 PP No. 22 Tahun 2021. Selain itu, pengaruh tata guna lahan terhadap kualitas air dikaji berdasarkan pengelompokan jenis aktifitas sepanjang aliran sungai. Dari hasil pengukuran parameter uji didapatkan kualitas air belum memenuhi baku mutu kecuali untuk kandungan Amonia pada titik hulu dan tengah. Beban pencemaran untuk setiap parameter uji hampir semuanya melebihi daya tampung. Aktivitas pemukiman, persawahan dan perkebunan memiliki dampak yang sama terhadap nilai parameter uji di ketiga titik. Sedangkan pada bagian hilir, Amonia terakumulasi mengakibatkan perbedaan yang signifikan dari titik lainnya.

Abstract

Microplastics (MP) can pose a serious threat to the environment and human health because of their tiny size and ability to spread easily in water. One of the alternative treatments to remove MP from water is the rapid sand filter (RSF). The objective of this study was to analyze the effects of filter media size and loading rate on RSF performance in removing MP. The applied filter media was silica sand with effective sizes (ES) of 0.39 and 0.68 mm. The loading rates of filtration were 4; 6; 8 and 10 m3/m2-h. The MP samples were made from plastic bags and torn tires (artificial samples: 10 to 800 µm). This study showed that the MP removal percentage was up to 96.6% (MP size larger than 200 µm). The head loss increment for loading rates 4; 6; 8; 10 m3/m2-h was 0.16; 0.35; 0.34; 0.25 m (ES 0.39 m) and 0.10; 0.18; 0.18; 0.19 m (ES 0.68 m)), respectively. Meanwhile, the filtration cycle for loading rates 4; 6; 8; and 10 m3/m2-h was 5, 2, 2, and 1 days (ES 0.39 mm) and 9, 4, 3, and 3 days (ES 0.68 mm), respectively. The result of this study showed that the smaller the filter media size, the higher the head loss of the filter media bed. Furthermore, there is an increased head loss of the filter media bed when the loading rate is greater.

Abstract

According to data from the National Waste Management Information System (SIPSN) for 2020, the largest pile of waste according to waste sources in Lampung Province comes from household waste, namely 42%. Along the Dusun II road in Way Hui Village, almost every day the community burns leaf litter in their yards, which causes pollution. In addition, according to data from the Central Statistics Agency (BPS) for 2020, agriculture in Lampung is the 15th highest, namely 90.48%. However, in its management, the majority of agriculture and plantations in Lampung use inorganic fertilizers to increase the quality and quantity of crops. This problem can be overcome by using organic waste as compost to gradually improve soil quality and reduce the volume of household kitchen waste. The Rotary Drum Biocomposter is a simple and inexpensive composter for processing kitchen and household organic waste in a sustainable manner. To speed up the composting process, a bioactivator is added as a decomposer. Bioactivators can be made by utilizing rice washing water waste and papaya fruit waste, which are rich in nutrients and can increase the macronutrients of the compost. The composting method used in this research is aerobic composting. This tool aims to educate the surrounding community that waste can be turned into valuable goods with good management, thereby creating a healthy environment and profitable business opportunities.

Abstract

The research on microplastics in urban drainage is becoming a concern. In the drainage of Bandar Lampung city, four different anthropogenic activities were investigated: road runoff, industrial activity, public place, and housing area. This study investigated the abundance, characteristics and distribution of microplastics (MPs) through drainage systems in dry weather. A total of sixteen drainage water samples were collected using grab sampling with a horizontal water sampler. Under microscope observation combined with a needle test, the average abundance of MPs was found 3.97±3.4 particles/L, with fibers as the dominant type of MPs. The order of MPs' abundance was industrial area > public area > transportation area > housing area. However, this number of MPs tends to be lower compared to other reported studies. The size of MPs mostly ranged from 500 - 1500 µm (36%). The color of MPs was amply diverse, with blue being in the dominant proportion (43%). Other studies also reported similar findings regarding the type and size range. Through Raman spectroscopy, the identification of polymer types indicated the presence of polyethylene terephthalate. From the correlation analysis, it was found that there was a positive correlation between the abundance of MPs and flow rate discharge, though with a low relationship (r=0.46). This result can be influenced by several factors such as the effects of multiple land use types and pollution sources. The significance of this research lies in its contribution to understanding the extent of microplastic pollution and its potential environmental impact on the Lampung water body.

Abstract

Wastewater from restaurant activities contains organic compounds such as carbohydrates, proteins, fats, and oils that can pollute and damage the environment. Therefore, further research is needed to prevent this pollution. This study aims to analyse the characteristics of restaurant wastewater and utilise kapok banana peel waste as a natural coagulant to reduce TSS (total suspended solid) and COD (chemical oxygen demand) concentrations in the wastewater. Additionally, this study aims to analyse the correlation between the reduction in TSS and COD concentrations after the coagulation process. The results showed that kapok banana peel powder has polyelectronic properties and contains carboxyl, hydroxyl, and amide groups acting as active components in the coagulation-flocculation process. The coagulation-flocculation process was efficient at 400 mg biocoagulant, with reduction efficiencies of 92% for TSS and 73% for COD. Based on Pearson correlation analysis using SPSS, the reduction in TSS and COD concentrations had a very strong (r=0.954) and significant (Sig.=0.000) relationship.
