Abstract
Garut Regency is flanked by three mountains, namely Papandayan, Guntur, Cikuray. Some are coastal areas in the south of the Garut Regency. Cikandang River has the potential to meet the needs of micro-hydropower plants. The utilization of the Cikandang river is used as a micro-hydropower plant with a power of 1 MW to 10 MW. The locations of the Cikandang 1 and Cikandang 2 micro-hydropower plants nearby use the same potential discharge from the Cikandangriver. In practice, the use of this river has a difference between PLTM Cikandang 1 of 6 MegaWatts and Cikandang 2 of 3 MW. The method is based on a pre-planned design layout. The calculated discharge is the mainstay discharge or the availability discharge calculated based on the FJ Mock method with a probability of 85% with ten years of rain data. Available discharge on the Cikandang river is 12.88 m3/sec, and the head is 32.7 m with head losses 0.86 m, and system efficiency is 0.69. The output power of the Cikandang 2 micro-hydropower plant is 2.88 MW. The difference between the Cikandang 1 and 2 micro-hydropower plants lies in the height of the head.

Abstract
The construction industry undeniably contributes to the CO2 emission to the earth due to the time-consuming process and high energy needed. Steel, concrete, iron, glass and plastic material are commonly used in the construction site so as the waste can be seen around. Construction waste treatment is potentially reused for another construction product due to its good material properties. Rebar tie wire is one of the beneficial construction wastes besides steel due to its remarkable tensile properties about 173 MPa. Utilization of rebar tie wire addition for enhancing the mechanical properties of a paving block will be the focus of this paper. The percentage of the rebar tie wire addition was limited until 3.5% to the weight of cement. The water-cement ratio of the paving block mixture was locked to 0.3, other than that the proportion of cement to sand was 1 to 2.5. The target of A type of paving block based on SNI 03-0691-1996 was reached by the addition of rebar tie wire between 2% and 3.5% which best compressive strength of 46.67 MPa resulted from 3% of addition. Moreover, the abrasion and absorption test showed the same good result as the quality of compressive strength.

Abstract
The utilization of slag as cement replacement has been widely developed for the concrete mixture. It is shown by the increment of the concrete performance even though unique characteristics during the cement-slag reaction were present. Slag is the waste of the steel industry which has various qualities. Unfortunately, this type of waste is not well identified in past research as supplementary material for the concrete. This paper will study the best proportion of slag cement as supplementary material in concrete for the special use of the rigid pavement. Solely, the mix design criteria for the experiment is not available yet so that preliminary experiment both physical and chemical are investigated for the special purpose of the target of minimum high strength concrete of 35 MPa. The chemical substances of two main oxides of sodium and potassium from ordinary Portland cement is essential to see the alkali activity that leads to the strength quality of the concrete specimen. Otherwise, the consideration of water-cement ratio must be relevant to the quality of concrete matrices.

Accordingly, this paper discusses the significance of organic waste-based material from the coffee powder utilized as the 5% cement replacement in concrete. Ultimately, the temperature variation of the muffle furnace to derive into coffee grounds husk ash is investigated chemically and mechanically to the compressive strength of concrete. Furnace temperature variation was set from 600°C up to 750°C for 2 hours which disclosed dominant potassium oxide. Else, some chemical components as found in cement was present except silicon oxide which predominantly appears in cement to increase concrete strength. However, the chemical reaction between coffee grounds ash, cement and other matrices in concrete mixture generated better compressive performance in accordance with the furnace temperature of 750°C climb reaching over 40 MPa which was above the targeted control sample. Even though the reactivity of the mixture was not detail observed, the coffee grounds ash obtained from 750°C furnace process was eligible as cement replacement in the concrete mixture for normal concrete design.

Published: March 2021

Abstract
With the development of communication and automation technology at this time, the Robot is widely used as a tool to assist the task of long-distance operations in the army combat unit. Especially for tasks that require high mobilization and tasks that have a relatively high level of danger, therefore the use of Unmanned Aerial Vehicles for remote sensing is developing very rapidly both in the field of civilian and military defense equipment. So in this study the researchers will develop the use of UAVs, especially in the type of quadcopter drones for remote sensing enemy areas. In this case, enemy surveillance still uses a lot of personnel, so monitoring the area requires a large amount of personnel. Conditions like this that can require high concentration and will drain personnel and logistics. The use of this remote sensing robot can minimize the use of TNI AD personnel directly, because in the sensing it is replaced by the role of visualization on the drone and has the ability to determine recognize the enemy by adding a face recognition system, so that later the tool is able to recognize enemies by detecting captured faces by the drone’s camera.
