Abstract

ABSTRAK: Aliran pada saluran terbuka dapat mengalami pembendungan apabila ada struktur bangunan ambang. Aliran akan mengalami perubahan kecepatan baik sebelum dan setelah melalui ambang. Perubahan kecepatan ini mempengaruhi pola distribusi kecepatan aliran yang berbeda di tiap kondisi aliran. Tujuan penelitian ini adalah untuk mengetahui pola distribusi aliran yang terjadi baik pada sebelum dan setelah ambang lebar. Selain itu, penggunaan ambang lebar pada penelitian ini juga bertujuan untuk mengetahui perubahan nilai koefisein debit (Cd) terhadap tinggi ambang lebar. Penelitian ini menggunakan saluran terbuka lurus (flume) berpenampang persegi dengan dasar tetap (fixed bed) dan tanpa kemiringan serta memiliki dimensi lebar (B)=7,6 cm, tinggi (H)=25 cm, dan panjang (L)=900 cm. Alat yang digunakan untuk mengukur kecepatan aliran pada penelitian ini adalah tabung pitot. Penelitian ini menggunakan 2 debit pengaliran (Q) dengan Q1=4,017 l/dt dan Q2=3,437 l/dt. Selain menggunakan 2 debit pengaliran, penelitian ini juga menggunakan 2 variasi tinggi (P) ambang lebar dengan P1 = 10 cm dan P2 = 12 cm. Dari hasil pengukuran dan perhitungan didapatkan bahwa aliran sebelum dan setelah ambang adalah subkritis. Pengukuran pada 4 section sebelum ambang menunjukkan bahwa semakin mendekati ambang kecepatan aliran semakin rendah, sedangkan pada 3 section sesudah ambang kecepatan aliran semakin ke hilir semakin tinggi. Kecepatan geser dihitung menggunakan metode Clauser. Pada hulu ambang pola distribusi aliran di daerah inner region memiliki nilai yang cukup berhimpit dengan perhitungan metode Logarithmic Law dan Von Karman tetapi di area outer region tidak. Pada hilir ambang pola distribusi aliran memiliki nilai yang jauh berbeda dengan perhitungan metode Logarithmic Law dan Von Karman baik pada daerah inner maupun outer region.Kata Kunci: saluran terbuka, distribusi kecepatan, ambang lebar, tabung pitotABSTRACT: An open channel flow over broad-crested weir will have different velocities in the upstream and downstream. This will also affect the velocity distribution that is vary in each flow condition. The objective of this study is to investigate the flow velocity distribution over broad crested weir. Moreover, the use of broad-crested weir was also to study the change of its discharge coefficient (Cd) over different weir heights. This study was conducted using a straight, rectangular channel (flume) with fixed horizontal bed and with dimensions of width (B)=7,6 cm, height (H)=25 cm, and length (L) = 900 cm. Pitot tube is used as flow velocity measuring instrument. There are 2 discharges used in this study, Q1 = 4,017 l/sec and Q2 = 3,437 l/sec. In addition, this study is also using 2 height variations (P) which are P1 = 10 cm and P2 = 12 cm. From the results of the measurements and calculations found that the flow in the upstream and downstream is subcritical flow. Velocity measurements in 4 sections before weir showed that the closer flow to the weir, the lower flow velocity. While in the 3 sections after the weir showed that the further the flow from weir, the higher flow velocity. Shear velocity was calculated using the Clauser method. Velocity distribution on the upstream inner region had values that coincide with Logarithmic Law as well as Von Karman but not on the outer region area. In the downstream, velocity distribution had values that is not in accordance with the calculation of Logarithmic Law and Von Karman method both in the inner and outer region.Keywords: open channel, velocity distribution, broad crested weir, pitot tube.

Abstract

ABSTRAK: Saluran terbuka merupakan saluran yang memiliki parameter yang tidak teratur, sehingga penyelesaian pada saluran terbuka sulit untuk diselesaikan secara analitis. Pada saluran terbuka sering terjadi aliran tidak seragam salah satunya karena adanya bendung yang mengakibatkan terjadinya perlambatan laju aliran. Tujuan dari penelitian ini adalah untuk mengetahui distribusi kecepatan aliran dan tegangan geser, serta arah vektor aliran. Dalam penelitian ini digunakan saluran dengan lebar 7.6 cm dan tinggi 25 cm. Kecepatan aliran diukur menggunakan Acoustic Doppler Velocimeter (ADV) tipe downlooking produk dari SonTek, San Diego USA. Dari hasil pengukuran inisiasi menggunakan ADV didapatkan debit sebesar 2.3 lt/det dengan sampling rate sebesar 50Hz dan velocity range sebesar 30 cm/det serta jumlah pengambilan data setiap titik pengukuran sebanyak 7500 data. Dari hasil pengukuran dengan menggunakan Acoustic Doppler Velocimeter menunjukkan bahwa nilai distribusi kecepatan aliran terbesar terjadi pada tinggi ambang 13cm section 180 pada kedalaman 11.908 cm sebesar 18.833 cm/det. Dan semakin ke hilir kecepatan aliran semakin kecil. Dengan menggunakan persamaan distribusi kecepatan teoritis (Von karman dan Logartimik) dibandingkan dengan data ADV menunjukkan bahwa section 30 sampai 180 memiliki bentuk grafik yang hampir berhimpit, sedangkan untuk section 10 memiliki grafik yang berbeda karena adanya pengaruh dari ambang tajam. Vektor aliran pada section 30 sampai 180 arah vektornya cenderung longitudinal, sedangkan pada section 10 arah vektornya cenderung vertikal karena pengaruh limpasan aliran diatas ambang. Nilai tegangan geser terbesar terjadi pada daerah inner region dikarenakan pengaruh dari gesekan dasar saluran.   Kata kunci: Aliran Diperlambat, Acoustic Doppler Velocimeter, Distribusi Kecepatan, Vektor Aliran, Tegangan Geser.   ABSTRACT: Open channel has irregular channel parameters, so the solutions of open channel it is hard to be solved analytically. In open channels there is often non uniform flow, for example because of the weir and it causes a decrease in the flow rate. The purpose of this study was to determine flow velocity and shear stress distribution, and the direction of the flow vector. In this study used a channel width of 7.6 cm and height of 25 cm. Flow velocity is measured using the downlooking type Acoustic Doppler Velocimeter, the product from SonTek, San Diego USA. From the result of the measurement of initiation using ADV the discharge was 2.3 lt/sec with a sampling rate of 50Hz and a velocity range of 30 cm/sec and the amount of data collection for each measurement point is 7500 data. The measurement using the Acoustic Doppler Velocimeter shows that the largest flow velocity distribution value occurs at a weir height of 13 cm in section 180 at a depth of 11.908 cm at 18.833 cm/sec. And the more downstream the flow velocity gets smaller. Using the theoretical velocity distribution equation (Von Karman and Logarithmic) compared with ADV data shows that section 30 to section 180 have a graph that is almost coincide, while for section 10 has a different graph because the effect of the sharp crested weir. The flow vector in section 30 to section 180 the direction of the vector tends to be longitudinal, while in section 10 the vector direction tends to be vertical because the effect of runoff flow above the sharp crested weir. The largest value of shear stress occurs in the inner region because the effect of the friction at the base of the channel.

ABSTRAK: Aliran pada saluran terbuka akan mengalami perubahan kecepatan apabila ada bangunan pintu sorong. Aliran akan mengalami perubahan kecepatan baik sebelum dan setelah pintu sorong. Perubahan kecepatan ini mempengaruhi pola distribusi kecepatan aliran yang berbeda di setiap kondisi. Tujuan penelitian ini untuk mengetahui distribusi kecepatan aliran dan tegangan geser di depan pintu sorong dengan menggunakan Acoustic Doppler Velocimeter atau ADV dan menggunakan persamaan teoritis (persamaan Von Karman dan Logaritmik), serta mengetahui vektor aliran yang terjadi di depan pintu sorong. Penelitian ini menggunakan saluran/flume. Dari hasil pengukuran inisiasi didapat debit 2,3 l/det dengan velocity range 30 cm/det dan sampling rate sebesar 50 Hz dengan pengambilan data pada setiap titik pengukuran adalah 7500 data. Dari hasil pengukuran dengan menggunakan Acoustic Doppler Velocimeter (ADV) menunjukkan bahwa nilai kecepatan terbesar terjadi pada bukaan pintu sorong 2,3 cm di section 180 pada kedalaman 11,976 cm dari dasar saluran dengan nilai kecepatan sebesar 19,536 cm/det. Nilai kecepatan semakin ke hilir semakin kecil. Dengan menggunakan persamaan teoritis Von Karman dan Logaritmik dibandingkan dengan data ADV menunjukkan bahwa pada section 30 hingga section 180 mempunyai bentuk grafik yang hampir berhimpit, sedangkan untuk section 10 memiliki grafik yang berbeda karena letak section 10 yang paling dekat dengan pintu sorong. Vektor aliran pada section 30 hingga section 180 arahnya cenderung longitudinal, sedangkan pada section 10 arahnya cenderung vertikal karena pengaruh aliran dibawah pintu sorong. Nilai tegangan geser pada terbesar terjadi pada daerah inner region di setiap section dikarenakan pengaruh dari gesekan dasar saluran. Kata kunci: aliran diperlambat, Acoustic Doppler Velocimeter, distribusi kecepatan, vektor aliran, tegangan geser.

Abstract

ABSTRAK: Pada aliran tidak seragam pembagian distribusi kecepatan aliranya tidak merata pada setiap section atau titik pengamatan. Penelitian ini dilakukan pada saluran terbuka lurus dengan dasar tetap (fix bed), saluran terbuat dari acrylic dengan panjang 900 cm dan lebar 7,6 cm dan tinggi 25 cm. Kemiringan dasar saluran menggunakan sistem terjunan (adverse slope) dengan kemiringan -0,0171 agar tercipata aliran dipercepat dengan beda tingi muka air yang signifikan. Penelitian ini menggunakan 3 variasi debit yaitu Q1 3,95 lt/dt, Q2 2,38 lt/dt, dan Q3 1,12 lt/dt. Pengamatan kecepatan dilakukan pada 5 section pengukuran dengan jarak 10cm dari ujung terjunan, 20 cm, 50 cm, 50 cm, 50 cm menuju ke hulu saluran. Dari hasil pengamatan dan pengukuran aliran pada saluran adalah aliran subkritis dengan nilai Fr<1 sehingga pengukuran dilakukan dari hilir ke hulu. Pada pengukuran ketinggian muka air diketahui bahwa ketinggian muka air semkin berkurang dari hulu menuju ke hilir, dan dari pengukuran kecepatan dengan menggunakan tabung pitot menunjukan peningkatan kecepatan dari hulu ke hilir saluran. Pengukuran kecepatan aliran secara teoritis dihitung dengan menggunakan metode Logaritmik dan Von karman. Hasil perhitungan kecepatan secara teoritis mendekati hasil pengukuran kecepatan dengan menggunakan tabung pitot pada daerah inner region dan semakin menjauh pada daerah outer region pada semua section pengukuran. Kecepatan geser dasar dihitug dengan menggunakan metode Clauser, dan didapatkan nilai tegangan geser dasar yang semakin ke hilir nilainya semakin besar. Kata Kunci: Distribusi kecepatan, aliran dipercepat, aliran tidak seragam, saluran terbuka ABSTACT: Velocity distribution in non-uniform flow is not evenly distributed in each point of observation. This study was conducted on a straight open channel with a fixed bed, made of acrylic with a length of 900 cm, width of 7.6 cm and a height of 25 cm. The channel bed is made with a drop structure (adverse slope) with a slope of -0.0171 so that the flow rate is accelerated with a significant difference in water level. This study uses 3 variations of discharge, such as Q1 3.95 l/s, Q2 2.38 l/s, and Q3 1.12 l/s. Velocity ​observation was carried out on 5 sections of measurement with a distance of 10cm from the end of drop structure, 20 cm, 50 cm, 50 cm, 50 cm towards the upstream channel. From the results of observations and measurements, the flow on the channel is subcritical flow with a value of Fr <1 so that measurements were done from downstream to upstream. On water level measurements it is known that the water level may decrease from upstream to downstream, and from velocity measurements using pitot tubes shows an increase in speed from upstream to downstream of the channel. The measurement of flow velocity is theoretically calculated using the Logarithmic and Von Karman methods. The results of velocity calculations theoretically approach the results of velocity measurements by using pitot tubes in the inner region and getting farther away in the outer region in all measurement sections. The bed shear velocity was calculated using the Clauser method, and the value of the bed shear stress was getting higher as the flow reached the downstream.

Abstract

A common problem encountered in the development of the art of tarling is the negative understanding of the majority of people about tarling itself. Tarling is currently experiencing difficulties in returning to be the belle of art in Cirebon society. As the development of tarling is used for the entertainment side and little by little reduces the value of tarling itself. This has become a fundamental problem for people who consider the art of tarling to be a mere art without any significant value. The purpose of this study was intended to find out more about character education in the function and value of the cirebonan tarling art. This research method uses descriptive qualitative exposure with ethnographic research design to find out more about character education in the function and value of the tarling itself, as well as using literature study data collection techniques related to Tarling arts and music, as well as interviews with informants. In general, tarling music can be divided into two forms: classical tarling music and modern Cirebon rhythm tarling music. Modern tarling experiences the absorption of various types of music, including pop and dangdut. Little by little in modern tarling puts forward the entertainment and material aspects and little by little reduces the value and function of the art of tarling itself. Whereas classical tarling music still has strong functions and values in instilling character education in every element of the performance of the tarling itself in each of its elements

Abstract

Lesti watershed is a sub basin of Brantas River located in Malang Regency, which is the main source of inflow and sediment loads for the Sengguruh Dam. Human activities change the type of land cover by deforestation for the expansion of agricultural and residential areas. It makes a rapid increasing of runoff and discharges that were potentially carrying sediment into Lesti River. To measure surface runoff in a watershed can be held by modeling rather than directly in the field, it is cheaper and more effective with accurate results. This study is based on Soil Conservation Service (SCS) formula to illustrate surface runoff level by knowing curve number distribution. Using models based on land use changes in 2010, 2012 and 2017, generated by AV SWAT software, shows that increasing CN value each year affects the surface runoff, so there is a relationship between land use and runoff. The average CN value in 2010 is 63.644, 2012 is 63.942, 2017 is 65.49, while the average surface runoff in 2010 is 800.28, 2012 is 823.26, 2017 is 828.009. Conservation treatment on the area with a high CN value can reduce the surface runoff. It shows that watershed performance is getting better.

Abstract

Generally, the condition of the rivers in Indonesia are alluvial rivers which had meanders, where the change in the river bed topography often occur. One of the parameters associated with changes in the river bed topography is bed-shear velocity, or Reynolds stress. The bed-shear velocity can be calculated by the Reynolds stress distribution method and the Clauser method which commonly used in straight channels. In fact, on natural channel there is a curve and even a meandering channel. With more complex flow conditions, the use of the Clauser method in curved channels can be questioned, is it still accurate or not. In this paper, both methods will be discussed by comparing the measurement data in the laboratory using 180 curved channel with flat bed. The results of data analysis show that the use of these two methods in curved channels produces an average difference of around 19.81%, where the Clauser method gives greater results and better tendencies. Apart from the differences in the results given, it can be said that the Clauser method as well as the Reynolds stress distribution method can still be used to calculate the bed-shear velocity in the curved channel.

Abstract

Sungai memiliki kerentanan terhadap erosi atau pengikisan lapisan tanah yang terus terbawa oleh aliran air permukaan sampai akhirnya masuk ke badan sungai dan menyebabkan terjadinya sedimentasi. Sedimentasi terutama sedimen suspensi menjadi sumber dari banyak permasalahan pada sumber-sumber air dikarenakan membawa sedimen bersamaan dengan aliran air. Berdasarkan hal tersebut menjadi penting untuk diketahui angkutan sedimen suspensi dalam menyelesaikan masalah pada sumber-sumber air, akan tetapi dalam perjalanan nya penentuan angkutan sedimen suspensi seringkali tidak sesuai dengan keadaan yang sebenarnya dalam merepresentasikan nilai angkutan sedimen suspensi. Untuk mengatasi masalah tersebut dilakukan penelitian untuk melihat bagaimana hubungan antara debit aliran dengan debit angkutan sedimen suspensi. Penelitian dilakukan pada anak sungai Brantas yang terdapat di Desa Torongrejo, Kota Batu. Penelitian dilakukan sebanyak sepuluh (10) kali pengambilan sample pada waktu yang berbeda menggunakan alat Portable TSS Meter type TSS 740 Partech uantuk mengetahui nilai konsentrasi sedimen suspensi pada tiap kedalaman aliran. Penelitian menunjukkan adanya hubungan antara debit aliran terhadap angkutan sedimen suspensi dengan persamaan Qs = 7.597 Q1.465, didapati pula hubungan antara debit aliran terhadap konsentrasi sedimen suspensi rata-rata dengan persamaan C = 89.422 Q0.461, dan terakhir didapatkan besaran faktor eksponen Rouse berada antara range 0.013 – 0.080.Rivers are susceptible to erosion or erosion of the soil layer which is carried by surface water flow until it finally enters the river body and causes sedimentation. Sedimentation, especially suspended sediment, is the source of many problems with water sources because it carries sediment along with the water flow. Based on this, it is important to know the suspension sediment transport in solving problems at water sources, but in its journey the determination of suspended sediment transport has been often not in accordance with the actual situation in representing the value of suspended sediment transport. To overcome this problem, a study was conducted to see how the relationship between flow rate and suspension sediment transport discharge. The research was conducted on a tributary of the Brantas river located in Torongrejo Village, Batu City. The study was conducted ten (10) times of sampling at different times using a Portable TSS Meter type TSS 740 patch tool to determine the value of the suspended sediment concentration at each flow depth. The research shows that there is a relationship between flow rate and suspension sediment transport with the equation Qs = 7.597 Q1.465. There is also a relationship between the flow rate and the average suspension sediment concentration with the equation C = 89.422 Q0.461, and finally the exponential factor Rouse is located between the range 0.013 - 0.080.

Abstract

Studi ini bertujuan untuk mengetahui bagaimana penegakan hukum terhadap tindak pidana  penganiayaan yang dilakukan oleh orang tua terhadap anak kandung, apa saja faktor yang menyebabkan tindak pidana penganiayaan yang dilakukan oleh orang tua terhadap anak kandung, apa saja hambatan dalam penanggulangan tindak pidana penganiayaan yang dilakukan oleh orang tua terhadap anak kandung. Adapun metode penelitian yang digunakan ialah menggunakan metode penelitian secara yuridis empiris, penelitian empiris dapat diartikan sebagai ilmu pengetahuan sosial, yakni suatu pengelompokan ilmu pengetahuan yang fokus pada penelitian perilaku manusia dan lingkungan, dan penelitian ini bersifat hukum yang bertujuan untuk memperoleh sumber data langsung dari lapangan melalui wawancara. Hasil dari penelitian ini ialah, kasus penganiayaan ini tidak diselesaikan sampai ke pengadilan, pelaku tindak pidana penganiayaan hanya diberi arahan dan bimbingan supaya tidak melakukan perbuatannya, dan pada kenyataannya perbuatan tersebut terulang kembali, faktor yang menyebabkan terjadinya tidak pidana penganiayaan ialah karena faktor orang tua yang tempramental/ringan tangan dan memiliki sifat emosional yang tidak terkendali, dan hambatan dalam penanganan kasus penganiayaan ini ialah, aparat penegak hukum mempunyai kesulitan dalam mencari informasi terhadap warga sekitar, karena IL mempunyai sifat yang tempramental yang membuat IL tidak pernak bersosialisasi dengan warga lainnya. Dan pihak kepolisian juga memiliki hambatan yaitu tidak tersedianya fasilitas rumah aman bagi anak yang sedang terkena kasus tindak pidana penganiayaan.
