Abstract

Erosion is a serious problem in watershed management. The Saba watershed is a water catchment area at the Titab Dam in Buleleng Regency, Bali Province. The existence of the Titab Dam is accompanied by the development of activities of the surrounding community, both tourism, economic and daily activities. Unfortunately, this activity in the future will have a negative impact on the condition of the dam so that it poses a risk. This study aims to determine the amount of sediment inflow with land erosion approach at the Titab Dam using the USLE (Universal Soil Loss Equation) method. Erosion rate prediction was carried out using the USLE method and with the help of ArcGIS 10.8 software. From the results of the analysis, it was found that in the Titab Dam catchment area, only 3 classes were obtained. The results of the calculation of the erosion rate using the USLE method showed that the magnitude of the erosion was 439,962 tons/year or 53.05 tons/ha/year. In addition, the most influential factors on the rate of erosion are the length and slope factors. In addition, land cover is also one of the most influential factors.

Abstract

Pore water pressure readings (piezometer readings) produce data that must be interpreted before being used for further analysis. This process is very influential on the results of the analysis because in the piezometer reading there is the possibility of anomalies due to potential delays or lags or errors in readings. The purpose and objective of this research is to provide an alternative approach to dam safety instrumentation inventory in order to be able to arrange maintenance work properly, effective and efficient, in conditions of limited budget can be used as a standard in making decisions in prioritizing piezometer maintenance. Several piezometer data processing methods can use techniques, including : interpretation of pore water pressure patterns; correlation simulation of pore pressure values and flow line plots. The results of the research on the piezometer at the Sermo Dam can be distinguished between conditions that have good pore water pressure readings and the opposite condition, with a ratio of 71,43% and 28,57%.

Abstract

Pidekso Dam is located in Pidekso Village, Wonogiri Regency, Central Java Province. The Pidekso Dam Spillway Building mode test was carried out to verify any deficiencies or design errors that might occur. One of the scope works in spillway model is a carrier channel downstream of the spillway which is 360 m long. To overcome the scour that occurs in the carrier channel downstream of the spillway, in the 4th series test, a groundsill structure was installed as a basic stabilizer for the carrier channel. The method is used in modelling include physical modelling, drainage testing, and observation of water flow and scouring that occurs at the bottom of the channel. The carrier channel groove model and the groundsill structure are made with a 1:40 scale both upright and flat (without distortion). The model test shows that the water flow in the carrier channel upstream of the groundsill is even and uniform with the bottom material of the channel not moving. At the bottom of the channel on the outer side of the bend which is assumed to be granular material, it is scoured to a depth of 2.68 m on the Z9 profile. This profile needs to be protected by rip-rap of concrete blocks, unless the base of the existing channel is a hard bedrock.

Abstract

A dams must always be maintained for their performance, function, and safety, so it is necessary to carry out various maintenance, repairs, and rehabilitation on dams that have been built and operating. Priority systems for the implementation of repair and rehabilitation of dams can be arranged based on the status of safety hazards or the level of risk of failure due to natural disasters or other consequences. Based on this, it is necessary to carry out an assessment of the dam to estimate the magnitude of the risk to the dam. According to the Risk Analysis Guidelines, the estimation of the probability of failure can be done using two methods, namely the traditional method and the event tree method. Based on the results of assessment analysis, the risk probability of the Kedungombo Dam with the traditional method and the event tree method is 4,010 x 10-1 and 1,548 x 10-3 where the acceptable limit conditions for the existing dam are a maximum of 1,000 x 10-5. The risk probability value of the Kedungombo Dam does not meet the requirements of an acceptable risk value. Therefore, it is necessary to recommend risk reduction for the risk assessment results. ABSTRAKBendungan harus selalu dijaga kinerja operasi, fungsi, dan keamanannya, sehingga perlu dilakukan berbagai kegiatan pemeliharaan, perbaikan, dan rehabilitasi pada bendungan yang sudah terbangun dan beroperasi. Sistem prioritas pada pelaksanaan kegiatan perbaikan dan rehabilitasi pada bendungan dapat disusun berdasarkan status bahaya bendungan dari segi keamanan atau besarnya risiko terhadap kegagalan bendungan akibat bencana alam maupun akibat lain. Berdasarkan hal tersebut, maka perlu dilakukan penilaian risiko pada bendungan untuk memperkirakan besarnya risiko bahaya pada bendungan. Berdasarkan Pedoman Analisis Risiko, perkiraan probabilitas kegagalan dapat dilakukan dengan dua metode yaitu metode tradisional dan metode pohon kejadian (event tree). Berdasarkan hasil analisis penilaian risiko, probabilitas risiko Bendungan Kedungombo metode tradisional dan metode pohon kejadian sebesar 4,010 x 10-1 dan 1,548 x 10-3 dimana syarat batas yang dapat diterima untuk bendungan eksisting maksimum 1,000 x 10-5. Nilai probabilitas risiko Bendungan Kedungombo tidak memenihi syarat nilai risiko yang dapat diterima. Dengan demikian, diperlukan rekomendasi tindakan pengurangan risiko untuk risiko hasil penilaian tersebut.

Abstract

The Ketupat Eid tradition is one of the cultural heritages of the Javanese people which is still preserved today. Eid Ketupat (kupatan) has deep value and meaning in several aspects, namely in the religious aspect as a means of spreading Islamic religion, strengthening ties of friendship, as an expression of gratitude to Allah SWT for the success of fasting during the month of Ramadan. In the spiritual aspect there is interaction to forgive each other, then in the social aspect it is a form of mutual cooperation, while in the economic aspect it can increase people's income by selling coconut leaves or palm leaves.Apart from having social meaning and value, the kupatan tradition also has symbolic meaning, namely Eid as a symbol of the end and end of the fasting month of Ramadan, luberan as a symbol of an invitation to share one's fortune by giving zakat and alms, melting as a symbol of admitting mistakes and forgiving each other, and laburan as a symbol so that humans always maintain their physical and spiritual purity. Apart from containing symbolic meaning, the Eid Kupatan tradition also contains cultural meaning, namely a means of communication and friendship, a means of giving alms, a means of honoring guests and a means of preserving ancestral traditions.
