Abstract

Considering the abundance of potential pollutant sources along Bedog River, i.e. highly dense residential areas, agricultural lands, and industrial areas, this study aimed to quantitatively assess the Pollutant Load (PL) and Pollutant Carrying Capacity (PCC) of the river based on Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)parameters. The assessment employed a water quality modeling using Qual2Kw that provided not only the comprehensive values of PL and PCC but also the amount of PL that should be reduced to meet the PCC of every river segment. Water sampling and primary parameter measurement were conducted purposively in seven observation points, which included one point source and six non-point sources (river segments). River segments were determined according to the characteristics of land use and drainage system. Descriptive, graphic, and spatial analyses on water quality modeling show that the COD and BOD of Bedog River (2.24 km) indicates a small presence of PL compared to the river?s PCC. The PCC allows additional pollutant loads of 566.95 kg/day or 0.024 ton/hour BOD and 22,965.12 kg/day or 0.96 ton/hour COD. However, a high BOD in segments 3, 5, and 6 and a high COD in segment 5 imply the needs for PL reduction.

Abstract

AbstrakRendahnya tingkat pelayanan jalan menjadi salah satu permasalahan yang ada di Koridor Jalan Godean. Permasalahan tersebut dapat di atasi dengan pengendalian penggunaan lahan serta penyediaan angkutan massal. Penelitian ini dilakukan untuk memodelkan tingkat pelayanan jalan jika terjadi perubahan penggunaan lahan sesuai dokumen Rencana Detail Tata Ruang (RDTR) serta pemodelan jika dilakukan pembangunan angkutan massal. Metode yang digunakan dalam penelitian ini yaitu metode kuantitatif. Metode kuantitatif digunakan untuk menghitung nilai VCR (Volume - Capacity Ratio) eksisting, nilai VCR dengan pemodelan pembangunan sesuai RDTR, ketentuan nilai intensitas bangunan ideal, dan nilai VCR dengan pemodelan pembangunan angkutan massal. Hasil penelitian menunjukkan bahwa tingkat pelayanan jalan pada kondisi eksisting masih sangat rendah dan jauh dari kondisi ideal. Kondisi ini diperakan sama dengan yang terjadi di masa mendatang, bahkan tingkat pelayanan jalan di sebagian segmen jalan akan semakin menurun. Potensi volume kendaraan tidak dapat ditampung oleh ruas jalan yang ada. Ketentuan intensitas bangunan perlu diturunkan sebesar 44,5% di segmen 2 dan sebesar 74,9% di segmen 4 dari nilai koefisien nilai bangunan (KLB) yang sudah direncanakan. Selain menurunkan intensitas bangunan, tingkat pelayanan jalan dapat ditingkatkan dengan pembangunan angkutan massal. Hasil pemodelan menggunakan angkutan massal menunjukkan bahwa moda transportasi yang masih memungkinkan untuk dibangun di Koridor Jalan Godean yaitu monorail dan trem dengan model jalur trem tidak eksklusif. Namun, jika pembangunan angkutan massal yang dipilih berupa trem, maka masih diperlukan penurunan ketentuan intensitas bangunan sekitar 37,8% di segmen 2 dan sekitar 68,78% di segmen 4 dari nilai KLB yang sudah direncanakan. AbstractThe low road service of Godean Corridor has become problematic. Since this problem can be dealt with by controlling land use and providing feasible mass transportation, this research aimed to model the level of road service if the land use change occurred in line with the Detailed Spatial Plan (DSP) and in the case of mass transportation development. The research used a quantitative method to calculate the existing Volume-Capacity Ratio (VCR), the VCR in DSP-based development model, the prerequisites for ideal building intensity, and the VCR in mass transportation-based development model. The results showed that the current road service was very low and far from ideal. This condition was estimated to persist in the future. The road services in some segments were also estimated to decline continuously. The current road could not accommodate the existing and potential of the traffic volume. The stipulation of building intensity has to be reduced by 44.5% in segment 2 and 74.9% in segment 4 from the previously planned building value coefficient. Aside from reducing the building intensity, the road service can also be increased by developing mass transportation. The results of mass transportation modeling showed that the feasible modes of transportation on the corridor were monorail and tram with non-exclusive tramway model. However, if the selected transportation is tram, then the building intensity has to be reduced by 37.8% in segment 2 and 68.78% in segment 4 from the predefined building value coefficient.

Abstract

Lahan sawah di wilayah Semarang dan sekitarnya berada pada dataran rendah pesisir yang rawan banjir, baik yang disebabkan oleh curah hujan yang tinggi maupun rob. Analisis risiko banjir diperlukan karena banjir merupakan ancaman bagi lahan sawah. Banjir dapat menyebabkan berkurangnya produktivitas lahan sawah, bahkan lahan sawah akan rusak dan tidak dapat ditanami padi jika tergenang banjir secara permanen. Penelitian ini bertujuan untuk menganalisis risiko banjir genangan pada lahan sawah berdasarkan kondisi bahaya dan kerentanannya. Lingkup penelitian mencakup analisis bahaya, kerentanan, dan risiko banjir genangan pada lahan sawah. Data yang digunakan dalam penelitian ini terdiri dari peta Rupa Bumi Indonesia (RBI), peta Sistem Lahan, citra penginderaan jauh resolusi tinggi, data curah hujan, debit sungai, tinggi pasang air laut, data statistik Potensi Desa (PODES), data statistik pertanian dan laporan banjir. Analisis kerawanan banjir merupakan gabungan antara kerawanan banjir genangan yang disebabkan oleh hujan dan rob. Analisis kerentanan banjir menggunakan data statistik PODES 2008 dan laporan kejadian banjir. Hasil penelitian menunjukkan bahwa banjir genangan rob merupakan ancaman dan berisiko pada pengurangan lahan sawah di wilayah ini. Selama periode 1994 – 2009 lahan sawah telah berkurang seluas 8.508,50 ha. Sebagian lahan sawah yang tergenang rob secara permanen telah dialihfungsikan ke penggunaan lain.Kata kunci: banjir genangan, rob, sawah, risikoABSTRACTPaddy field in Semarang and its surrounding areas are situated in low-lying flood-prone coastal area, whether caused by heavy rainfall and high tide. Flood risk analysis is required because flooding in this area is considered as a threat to the paddy field. Floods can lead to reduction of the paddy fields‟ productivity, even damaging and cannot be planted with rice if flooded occurred permanently. This study aimed to analyze the risk of flood inundation in paddy fields based on hazard and vulnerability factors.

Abstract

The measurement of 2D geo-electrical using Wenner Alpha configuration was conducted in the shore line of northern part of Ternate island, in order to know the depth of interface and to analyze the aquifers in conjunction with estimation of ground water potential. Water quality analysis is also conducted in some dug wells, such as in situ water temperature, electrical conductivity, pH, turbidity, dissolved oxygen, and salinity.Due to laboratory analysis, the values of measured parameters of water quality from some dug wells meets to the standards referred, especially for drinking water. The result of interpretation from geo-electrical data showed the depth of interface less than 10m.  From a drilled well data near shore line, indicate about 5m deep of interface. Base on geo-electrical survey, water quality analysis and field observation can be concluded that Ternate Island has limited potential of ground water, especially related to amount of fresh ground water. Which is now days, no alternative source yet of clean water for domestic use.
