Abstract

[EN] Run-off management is the main challenge of every big city. Land availability, project timeframe, and financing are several issues regarding run-off management implementation, including Indonesia’s Capital City, Jakarta. One of the engineering tools that used to reduce the negative impacts of run-off in Jakarta is Infiltration Well. Several researches on this topic confirm the positive impact of building infiltration well on small catchment area. This study aims to understand the efficacy of infiltration well project on big basin area, the Ciliwung Basin. Ciliwung basin is divided into two sub-basin, Upstream Ciliwung and Downstream Ciliwung. The analysis is performed using volumetric abstraction of infiltration well volume and daily infiltration rate. 4 rainfall stations are used in this study, 2-gauge rainfall stations on each basin. Infiltration well capacity is tested with different return-period rainfall based on daily and storm-rainfall (3-days cumulative rainfall). The results show that by implementing 1 million infiltration wells at each sub-basin the abstraction volume is below 10% for 10-year return period rainfall and below 5% for 25-year return period rainfall.

Abstract

Provinsi Riau merupakan salah satu provinsi yang memiliki garis pantai. Pulau Rupat merupakan bagian dari Provinsi Riau yang letaknya berbatasan langsung dengan Selat Melaka. Potensi Pulau Rupat sebagai wilayah pesisir banyak dimanfaatkan sebagai objek pariwisata, pemukiman dan industri. Sebagai pulau terluar di wilayah Negara Kesatuan Republik Indonesia (NKRI), maka perlu identifikasi dan pemetaan tingkat kerentanan pantai di Pulau Rupat sehingga dapat memberikan rekomendasi wilayah mana di Pulau Rupat yang harus diselamatkan dari kerusakan pantai. Metode penelitian yang digunakan yaitu berdasarkan pendekatan Indeks Kerentanan Pantai (IKP) dan Geographical Information System (GIS) untuk menentukan parameter perubahan garis pantai. Sedangkan data penelitan bersumber dari hasil survey lapangan kerusakan pantai di wilayah penelitian serta data citra satelit selama 20 tahun terakhir (2000-2020) untuk melihat besarnya perubahan garis pantai. Berdasarkan hasil analisis, tingkat kerentanan pantai di Pulau Rupat berada dalam kategori rendah hingga sangat tinggi dengan kondisi teknis mengalami abrasi maupun akresi. Penelitian ini juga memberikan hasil bahwa Desa Tanjung Jaya, Tanjung Punak, Teluk Lapin, Kedur, Makeruh, Pergam, Batu Panjang, Tanjung Kapal terjadi pengurangan garis pantai di mana Desa Pergam memiliki pengurangan garis pantai tertinggi yaitu sebesar 3,557 m/tahun.

Abstract

Kekeringan adalah salah satu bencana alam yang terjadi secara perlahan berlangsung lama hingga musim hujan tiba yang mempunyai dampak yang luas. Salah satu dampak kekeringan pada bidang pertanian pernah terjadi pada kabupaten Indragiri Hulu pada tahun 2015. Daerah irigasi (D.I) Kelayang merupakan daerah irigasi potensial yang mengairi wilayah pertanian di Kabupaten Indragiri Hulu. Untuk menanggulangi dampak kekeringan untuk masa yang akan datang perlu dilakukan peramalan indeks kekeringan. Indeks kekeringan sangat bergantung pada curah hujan. Untuk itu dilakukan peramalan curah hujan D.I Kelayang menggunakan metode Seasonal Autogressive Integrated Moving Average (SARIMA) karena diduga curah hujan merupakan data yang mengandung pola musiman. Kemudian dilakukan analisis indeks kekeringan menggunakan metode Standardized Precipitation Index (SPI). Hasil penelitian diperoleh model SARIMA (2,0,1)(0,1,1)12 merupakan model yang layak digunakan untuk peramalan karena telah melewati uji kerandoman dan kenormalan residual dengan mean squared dari residual yang terkecil yakni 4111,51. Setelah data peramalan curah hujan tahun 2019 didapatkan, dilakukan analisa indeks kekeringan dan diperoleh indeks SPI bernilai negatif yang tertinggi terjadi pada bulan Januari yaitu -0,252, sedangkan SPI bernilai positif tertinggi terjadi pada bulan Juli yaitu sebesar 0,169. Indeks kekeringan di D.I Kelayang bersifat “Normal”. Peramalan indeks kekeringan ini dapat menjadi informasi tambahan bagi Badan Nasional Penanggulangan Bencana.

Abstract

An earthen pond was built at the location of catfish farming in Rumbai Bukit Village. Water sources come from springs, rainwater and water flow from surrounding channels. The volume of pond water during the dry season continuously decreases. The water level is reduced by > 10% per day in ponds 1, 2, and 3. To overcome the pond water level lowering, a pump is needed to drain water from pond 3 to pond 1 at the filter pond with a power of 16.23 watts. With the power requirements and pump capacity, the Aqua 125 W Pump was chosen, with a capacity of 30 Lpm, with a total head of 37 meters. Measurement of water quality before installing the pump and water filter showed that the pH ranged from 6.5-7.4, TDS ranged from 68-78 ppm, and the temperature was 27-34⁰C and after the pump and water filter were installed it was seen that the pH ranged from 6.6-7, 8 (an increase), TDS ranged from 66-41 ppm and a temperature of 26-29⁰C (decreased). The results obtained indicate that the application of pumps and water filters facilitates water circulation in ponds 1, 2, and 3 as well as 4, 5. Extension activities on the design of the soil pond and the application of pumps and water filters have overcome the decline in pond water levels during the dry season.

Abstract

Farmers are concerned about the problem of drought in agriculture because it will disrupt the production system and cause losses. In 2015, the Indragiri Hulu area experienced a drought on 273 hectares of agricultural land. This area is part of the Indragiri River Watershed in Riau Province. To prevent the impact of future droughts, forecasting is required. The level of drought is influenced by rainfall, so the Seasonal Auto Regressive Integrated Moving Average (SARIMA) method is used to model rainfall data. In addition, the Standardized Precipitation Index (SPI) is also used to analyze the drought index. After the analysis, it was found that the best model in forecasting is SARIMA model (1,0,1)(2,1,1)12 with an average residual square of 18.0175, and the drought index in the Indragiri watershed is currently included in the  "Normal" category. The results of this forecasting are expected to assist the Riau Province National Disaster Management Agency in anticipating and mitigating the impact of future drought disasters.

Abstract

In Indonesia, the study of biomarkers is still very few because not many biomarkers are understood in various inland public waters here. The research location was at the Koto Panjang Reservoir as the experimental location and the Sei Tiban Fish Seed Center as the control location. The fish tested were carp and tilapia. Sample analysis was carried out in a certified laboratory at Construction Materials Laboratory, Department of Public Works, and Genetics Laboratory, Universitas Riau. The biomarkers studied were LSI, GSI and MT, and heavy metals observed were Cd, Pb and Hg. The research method was Experimental Design. Based on the statistical test, there was no difference in the LSI value of tilapia in the treatment group and tilapia in the control group (p = 0.187; p > 0.05), while it was different from goldfish (p = 0.0000; p < 0.001). In GSI, both of tilapia and carp showed significant differences (p = 0.0010; p < 0.010) and (p = 0.0060; p < 0.010). The tilapia and carp-treated livers showed the presence of MT while not in the control fish. This indicates that MT can be used as a biological marker of heavy metal exposure compared to GSI and LSI.
