Abstract

Sedimentation and erosion caused by differences in discharge is a problem that often occurs at river bends. One of the functions of placing the groyne is to reduce the river flow velocity along the riverbank, accelerate sedimentation, and ensure the embankment or river bank's safety against scouring. This study aimed to determine the distribution of current velocity, distribution of riverbed shear stress, and sediment distribution to the effect of groyne placement. There are 7 (seven) simulation models used to get the most effective groyne placement. From the model simulation results by adding a groyne building on the river's outer bend for the simulation model scenario 2 to scenario 7, the largest sedimentation production is in scenario 3, namely the height of riverbed sediment deposits 230 hours of 1.094 m. Furthermore, the groyne building's effective placement is determined based on a maximum change in the riverbed scenario. In scenario 3, the placement and dimensions of the groyne length of 17.5 m; distance between groyne 24.4 m; the groyne is inclined upstream in the direction of flow 10°.

Abstract

Servis kendaraan bermotor merupakan suatu kegiatan yang penting untuk memastikan kendaraan tetap berada dalam kondisi yang baik dan aman untuk digunakan. Namun dalam proses perbaikan kendaraan bermotor mekanik masih menemukan beberapa kendala salah satunya belum ada alat pembuka lempengan komstir motor, sehingga peralatan yang digunakan saat ini masih menggunakan alat seadanya seperti menggunakan palu dan obeng untuk membuka lempengan, sehingga waktu yang digunakan untuk membuka lempengan komstir motor masih membutuhkan waktu agak lama, selain dari itu juga pekerja mengalami cedera seperti tangan kena hantaman palu, kena ujung obeng sehingga mekanik dapat mengakibatkan kecelakaan kerja. Olehnya itu diperlukan rancangan alat bantu pembuka lempengan komstir motor dengan menggunakan metode Ergonomic Function Deployment (EFD), metode ini digunakan untuk mengidentifikasi dan memenuhi kebutuhan pengguna dalam perancangan produk, selain dari itu EFD juga dapat digunakan untuk memastikan bahwa alat tersebut dirancang agar efektif, nyaman, aman, sehat dan efesien digunakan oleh pengguna. Berdasarkan dari hasil korelasi antara customer needs dengan respon teknis maka yang menjadi prioritas utama dalam perancangan alat bantu adalah alat bantu pelepas komstir aman dan nyaman saat digunakan dengan total nilai 47 sedangkan prioritas terendah adalah proses perawatan mudah dilakukan dengan total nilai 9. Berdasarkan dari hasil pembahasan menggunakan metode EFD Menghasilkan rancangan alat bantu pembuka lempengan komstir motor yang  sesuai dengan spesifikasi keinginan pengguna dan menghasilkan rancangan alat bantu yang ergonomi

Abstract

The existence of batteries in the substation functions to maintain the stability and reliability of the DC electrical system, where the protection system on the control panel must not go out. Therefore, routine battery maintenance and testing are needed so that the battery can run properly and optimally. Battery testing is a routine agenda that is carried out every 6 months. For daily maintenance, a visual inspection (vision) can be carried out, while monthly maintenance is carried out in the form of a battery equalizing test which is carried out so that the 110V DC battery remains stable and can supply DC to auxiliary equipment when in an emergency. The test results obtained in this study were that the equalizing test on the 110V DC battery that was carried out obtained the battery results in normal conditions. This is explained, when the battery is connected to the load and the voltage per battery cell is measured in floating charging mode showing an average voltage of 1.34 V DC. When the battery is in equalizing charging mode, the voltage capacity on each battery cell can be said to be normal or stable with a total voltage value of 128.2 V DC and a temperature value of 27 ºC. For the measurement results of each battery cell after equalizing charging, the average voltage value per battery cell is 1.35 V DC with a total voltage of 116 V DC. It can be concluded that the equalizing test on the 110V battery unit 1 of the 150 KV Main Substation is fairly normal and the battery is ready when run in discharge mode

Abstract

Each type of rock has different resistivity values as well as durability. Continuous geoelectrical data is highly beneficial for estimating the distribution of rocks based on their resistivity values. The purpose of this study is to observe the resistivity patterns of each rock unit, both subsurface and exposed in the field, where each rock unit has specific durability values. The geoelectrical survey was conducted using the Dipole-Dipole and Wenner-Schlumberger methods with the Multichannel Resistivity MAE X 612 EM+ instrument. A case study was carried out at one of the excavation sites at Jragung Dam, with lithology consisting of sandstone and claystone of varying thicknesses. Claystone was identified as a weaker rock with lower durability compared to sandstone. The durability of claystone ranges from 18% to 60%, while the durability of sandstone exceeds 80%. Based on geoelectrical measurements using the Dipole-Dipole and Wenner-Schlumberger methods, as well as data processing with ERT LAB and Res2DINV software, sandstone generally has a resistivity of more than 18 Ohm.m, while claystone has a resistivity of 0–18 Ohm.m. It was observed that the resistivity values of claystone and sandstone are proportional to the durability of the rocks. The better the rock durability, the higher the resistivity value.

Abstract

Abstract. Law enforcement aims to create justice, certainty and benefits, in relation to drug abuse, law is one alternative solution to eradicate drug abuse, because the law contains a number of rules and provisions to ensure that the norms in the law are obeyed by the community. Drug abusers more often end up in prison than given the right to rehabilitation. The dimensions of health and recovery, both physical and psychological, through rehabilitation are less considered and tend to be sidelined. The imposition of sanctions for users should be more oriented towards the aspect of rehabilitation punishment rather than prison sentences, because this is to emphasize and clarify the sanctions between drug dealers and abusers. The approach method used is normative juridical, namely a library legal research conducted by examining library materials or secondary data only using deductive thinking methods. The writing specifications use descriptive analysis, the sources and types of data used are secondary data. The data collection method is by collecting data using secondary data collection methods. The problems are analyzed with the theory of law enforcement and the theory of legal effectiveness. For drug addicts or dealers as a substitute for imprisonment sanctions adopted from the double track system model, which is a two-track system regarding sanctions in criminal penalties, namely the type of criminal sanctions and the type of action sanctions. The guarantee of legal protection provided for drug addicts is regulated through Law No. 35 of 2009 concerning Narcotics by providing rehabilitation, both medical and social rehabilitation as stated in Article 54 of the narcotics law, namely that "drug addicts and drug abuse addicts are required to undergo medical rehabilitation and social rehabilitation. The effectiveness of law enforcement against dealers as perpetrators of drug abuse is still inconsistent with the government's implementation of the Law. So this provides a legal problem in dealing with this problem, in this case there needs to be a reconvention in the Law that can be implemented according to the circumstances that occur and does not change it at any time making this less effective
