Abstract

In river crossing operations using amphibious vehicles, the landing process is a critical point for the success of the operation. This study aims to obtain an overview of the potential failure of amphibious vehicles during landing due to the stability factor of the slope / slope caused by topographic conditions in the form of steep bank slopes and geological conditions in the form of poor soil bearing capacity. This study begins with observations on one of the rivers to obtain an overview of the presence of steep riverbanks, followed by a literature study on an amphibious vehicle, and observations of the landing process of an amphibious vehicle in training activities at the Gedebage reservoir, Bandung. This study obtains an illustration that there is an area in the watershed (DAS) with steep geometric shapes on its banks, which becomes an obstacle in the amphibious vehicle landing operation which will be found during the operation. Another illustration is when the steep banks of the river have low soil bearing capacity, there will be a potential failure of amphibious vehicles to land due to the collapse of the river bank slopes.

Abstract

Propellant is one of the national industries development program. Raw material of double base propellant is nitrocellulose and nitroglycerin. Nitroglycerin approved by country, but nitrocellulose still relies on imports. The need for nitrocellulose continues to increase and independence in the manufacture is very necessary to support alusista independence. Therefore, it is necessary to map the types of local plants needed to produce nitrocellulose. Method of this research is carried out a discussion from literature by tracing and collecting data taken with various references about plant which has potential as raw material for making nitrocellulose. The data collected is described as information describing plant species with the highest potential forproducing nitrocellulose. There are several plants that can produce nitrocellulose, including sago (Metroxylon sago Rottb.), Cotton (Gossyoium sp.), Kapok (Ceibe Petandra), Palm Oil (Arecaceae), Aren (Arenga pinnata), Pineapple (Ananas comosus) and Bamboo Beema (Bambusa balcoa). Most nitrocellulose by the process of nitration produced by cottonwood plants with levels reaching 50%. Several other types of plants have cellulose content. Most of the higher alpha cellulose include acacia (Acasia mangium), kenaf (Hibiscus cannabinus), Mangrove (Rhizophora) and banana klutuk (Musa balbisiana colla). Plants that have high cellulose content specially alpha cellulose content, can be using with chemically nitration processed to produce nitrocellulose. Further research is still needed to maximize the yield of nitrocellulose in local plants.

Abstract

The transfer of the capital ushered in a new geostrategic era. Nevertheless, the strategic location of IKN cannot be separated from the threat of defense and security disruptions carried out by state actors, non-state actors, and hybrids. This research aims to analyze the Utilization of UAVs Supporting the Air Defense of the National Capital (IKN) Nusantara as a Center of Gravity. Qualitative research methods with literature studies are used in this article. The results of the study revealed that to secure the nation's capital, air defense units must be added to vital locations. This is done by developing airbases of each province that need to be mobilized with ground forces and deploying fighter forces, and UAVs. Maximum airspace security is necessary to maintain sovereignty in the airspace because without it sovereignty will be threatened by aviation attacks from third parties. On the other hand, stakeholders are also expected to be ready, including governments, experts, and the media, which have a vital role in shaping public perceptions and perceptions of potential threats based on regional characteristics. In addition, considering that society is an actor who plays a very role in the defense and security of the country, it is known as the universal people's defense system (sishankamrata).

Abstract

The existing mass transportation cannot accommodate Jakarta’s population increase. The Central Statistics Agency stated that the number of vehicles in Jakarta in 2022 was 26.370.535. The high level of vehicle mobilization results in vehicle congestion in Jakarta. For this reason, it is necessary to have a mode of mass transportation to be a solution to solving congestion. Airships are air mass transportation with a propulsion system consisting of gas and engines. The design of the mode of transportation is carried out using a quantitative method through a literature review approach and numerical formulation analysis. The resulting airship designs have a capacity of 40 people, a total load of 9764 kg, balloon dimensions of 46 m x 13 m x 18 m, and gondola dimensions of 11 m x 4 m x 2m. This research provides a study of the design of mass transportation modes with air operations, which can be a solution to the congestion that occurs. Can reduce existing congestion with efficient routes for the mobilization process at work time.

Abstract

The maglev system is a technology that uses the repulsive force between magnets to float or levitate an object or vehicle. Maglev trains use electromagnets to counter the gravitational force of an object, so that the object can float in the air. With this technology, the resulting loss between the workpiece and the base can be eliminated. The technology used in this train is Electromagnetic Suspension (EMS). The research began by modeling the maglev system in the form of state space. Furthermore, the stability system model that has been built is analyzed. Finally, it is analyzed how the numerical simulation of an open loop without control is analyzed. The result of this research is that the floating system (maglev) is an unstable system if it is run in an open loop, so the maglev system requires sensors and controls in its operation.
