One industry that needs attention is Samarinda's woven sarong business. This industry produces liquid waste that is produced from the coloring process using De Congo Red which is an organic dye. Discussing the business of Samarinda's woven sarong industry discharges its waste directly into the Mahakam River around the house or weaving location which will cause a harmful impact on the environment. The main process in this research is adsorption with active bentonite to determine differences in activated bentonite particles in the adsorption process. The performance of the adsorption process through the parameters of BOD, COD, TSS and, pH of the liquid waste. The adsorption process was carried out by mixing active bentonite and Samarinda waste woven gloves with 0.25 grams: 1 mL. The mixture is then stirred for 1 hour at a rotational speed of 468 rpm. The size of the active bentonite was varied by 210, 230, 270, 310, 330, 370 and 400 mesh. The results of this study have proven that active bentonite has 400 mesh more than the BOD, COD, TSS and pH values according to the standard requirements according to the Decree of the Governor of East Kalimantan No. 26/2002. Also involved were 34.5 mg / L, 64 mg / L, 168 mg / L and pH 8.

Cooling system has an important role in motor vehicles, because its function is to maintain the working temperature of the engine, so that the temperature does not exceed the threshold (over heating), due to the frequent causes of excessive heat due to the use of cooling water in the radiator. The research method used is an experimental method, where the aim is to determine the effect of coolant on engine temperature from the use of several types of coolant additives. The cooling water used is coolant 30/70 pre-mixed and coolant predilute 33%. This test is carried out at rounds of [600, 1500, 2000, 2500, 3000] RPM. The object of this research is the Toyota Avanza Type E 1300 CC M/T. From the results of research on engine temperature data with the use of coolant 30/70 Pre-mixed at various variations of engine speed obtained an average temperature of 94.13 OC. While the use of coolant predilute 33%, the average temperature in testing reaches 94.4 OC. Based on the description of the results of the test data that has been done, it was concluded that the use of coolant 30/70 pre-mixed and coolant predilute 33% has the same effect on the temperature of the Toyota Avanza Type-E 1300 CC M/T engine.

A wiper is a device used to clean rainwater and particles from glass that can block the vision of heavy equipment operators during rainy weather. To clean rainwater from the glass, the operator must activate the wiper switch. When the operator is focused on work often the operator forgets to turn on the windshield wipers or turns off the windshield wipers, it can disturb the operator's concentration especially on the machine when working. Automatic wipers are devices that detect rainwater with the help of a raindrop sensor FC 37 to activate the wiper motor without the need to activate the switch. With this automatic wiper the operator can comfortably work when the weather is rainy. The purpose of making a microcontroller arduino ino R3 based automatic wiper simulation tool is as a learning media for wiper electrical system applications on heavy equipment. The results obtained from simulation testing based on the standard operating procedures that have been made and successfully work well without problems.

Crash box is one of the passive safety components in vehicles, especially cars that are designed to reduce the occurrence of injuries to drivers and passengers due to collisions. This study aims to determine the energy absorption of the crash box with a multi-segment circular cross section. The research method used is quasi-experimental, namely by computer simulation using Finite Element Method-based software. The independent variable in this study is the location of the segment connection, including: 1/4, 1/3, and 1/2 of the total length of the crash box. While the dependent variables that are sought include: energy absorption, force reaction, and deformation patterns that occur in the crash box. The crash box will be hit by an impactor with a mass of 103 kg and a speed of 7.67 m/s. From the simulation results, the maximum energy absorption and force reaction values are found in the crash box at connection 1/2 of 1689.7 J and 67718 N, followed by connection 1/3 with values of 1221.2 J and 56127 N, and the last is at 1/4 connection is 1119.8 J and 55443 N. Judging from the deformation pattern, the connection at 1/4 and 1/3 is buckling so that the energy absorption is lower than the crash box at the 1/2 connection. It is concluded that the most optimal design of the crash box with a multi-segment circular cross section is the model at the 1/2 connection because it has the highest energy absorption value of the other 2 models and the deformation tends to be more stable.

A repeatedly used cooking oil is also called as used cooking oil. Used cooking oil from 17 entrepreneurs in Palaran Sub-District is 161,5 liters/day or 50,65 tons/year. Used cooking oil can result in pollution to the environment due to the increasing number of acids and the number of peroxide. The research objectives of this literature study is to find out the effects of the mass adsorbent in the refining process of cooking oil with the activated charcoal adsorbent from sugar cane on the number of acids and the number of peroxide. A lot of sugar cane has a content of cellulose 45%, lignin 18%, Pentosan 32% and others 5%, so it can be used as a material of active charcoal which can be applied as adsorbent for the purification of used cooking oil. The process of refining the oil using adsorption method by varying the mass of active charcoal adsorbent. The collection of secondary data on the research of this literature was sourced from Triyanto (2013), Irmawati and Syahrir (2018) and Bariah (2020) who have examined the mass influence of active charcoal adsorbent on the number of acids and numbers of peroxide. Based on the results of analysis and interpretation of the third data of the journal used obtained information that the mass recommendation adsorbent on mass 6 grams

Fire is an accident that often occurs in the community. For that we need a tool that can provide early warning of a fire. There are many types of fire alarms. We design a fire alarm system using a microcontroller. By using this fire sensor, if a fire is detected, the sensor will send a signal regarding the presence of a fire. Flame sensor will be connected to the microcontroller. In this study using a microcontroller in the form of Wemos D1 and a flame sensor as a fire detection sensor and as an indicator light. The flame sensor itself can detect waves of 760 nm – 1,100 nm. Wemos D1 which functions as a microcontroller will send a signal to turn on the buzzer as an alarm and a dynamo which is used to turn on the pump.

Electrical energy is one of the most important daily needs for humans. Electricity is used to power tools that are used daily, such as turning on the lights, TV, refrigerator, and others. Electrical energy can be generated easily, there are already many power plants that can create electricity from new and renewable energy such as solar power plants (PLTS) and wind power plants (PLTB). The two generators can be combined to form a new system, namely the Hybrid system. In this study design a hybrid system of solar thermal energy and wind energy. The system formed uses a power storage system that is with a battery. Then the energy from the battery can provide energy to the load. The average power generated from the PLTS design is 0.474 Watt and the average wind generator is 9.378 Watt. Then the average hybrid system produces a power of 0.551 Watt.

Stator Generator is a stator that uses a generator consisting of a coil and a magnet that emits an alternating voltage so that it can rotate the flywheel, the stator generator is a product of the development of the Stator Motor whose production demand is always increasing. The Stator Generator consists of Flywheel Assy and Stator Comp. In the Manufacture Stator Comp process, the longest production process is wire cutting. This research started from finding the problem of long production time. In the process of cutting wire, it is still done manually using cutting pliers by the production operator. To meet daily production needs, this wire cutting process requires two employees to carry out the production process with an ever-increasing target. From these problems, a wire cutting machine based on Automatic Wire Cutting was developed in order to get maximum and efficient production results. Calculations in material selection and cutter angle are also considered so that the results of the wire cutting process are stable and produce good cuts.
