Soil in road pavement construction has an important role as the foundation for the structure supporting the load above it. The damage that occurs in road construction also often due to subgrade soil that does not have good bearing capacity, therefore soil reinforcement or stabilization is needed to improve its strength. The road section in Cibingbin Village, Cibaliung subdistrict, Pandeglang Regency was damaged due to a lack of soil bearing capacity, where through field CBR tests it was discovered that the CBR value of the soil was 3% less than required. Soil strengthening can be done by adding additional substances to the soil which can increase its strength and bearing capacity. Eggshell powder was chosen in this research as an additive to see its effect on soil strength. Soil strength is tested through unconfined compression stress (UCS) testing in the laboratory. Apart from that, the effect of adding eggshell powder on the physical properties of the soil was also studied. Variations in adding eggshell powder were taken in varying percentages 0%, 2%, 4%, 6%, 8%, 10%, 12% and 14%. The results of testing the physical properties of the soil showed that the original soil type was classified as organic clay with high plasticity (CH). The UCS test results on the original soil had a strength (qu) value of 1.6 kg/cm2, and the adding eggshell powder could increase the qu value which got optimum value at the percentage 12% eggshell powder with 0 and 3 days of curing of 2.851 kg/cm2 and 3.386 kg/cm2 respectively. It can be concluded that the addition of eggshell powder can increase the soil strength. The consistency of the clay soil changes to become stronger and based on the UCS value the clay soil becomes stiffer.

The wastewater in the washing process in Methyl Iso Cyanate production line contains ammonia which causes air pollution. Therefore, the ammonia waste processing system is needed that can degrade ammonia so that its concentration decreases and reduces the pollution. Photocatalytic degradation of ammonia is an attractive technology because of its easy operation, high efficiency, low cost, and low secondary pollutants. The photocatalytic process produces hydroxyl groups from the decomposition of water which can oxidize ammonia into nitrate and nitrogen gas. This research aims to process ammonia waste by combining adsorption and photocatalysis processes to obtain better performance in degrading ammonia. The research began with the preparation of activated carbon as an adsorbent and the synthesis of activated carbon-TiO2 composite material. Activated carbon is heated at 500º C for 6 hours for the activation process. Composite material synthesis is carried out using the slurry method. Activated carbon performance testing was carried out at weight variations of 10, 20 and 30 gram. Measurement of ammonia concentration was carried out using the spectrophotometry method. Optimum results were obtained at an activated carbon weight of 30 gram with a reduction in ammonia concentration of 1.01%. TiO2 as much as 5% of the weight of activated carbon (30 gram) is dissolved in ethanol and activated carbon is added to obtain a composite material. In the composite material performance test, a maximum reduction in ammonia concentration of 45% was obtained using the ultrasonic stirring method.

Indonesia is included in the category of countries with high disaster risk, including the risk of fire disasters. However, the lack of public awareness makes planning risks greater, such as physical losses, minor injuries, and even fatalities. Therefore, good mitigation is needed to reduce this risk. The research aims to propose disaster mitigation for fires in high-buildings. One thing that can reduce casualties is evacuation. The success of an evacuation can be seen from the evacuation time. The research locus is one of the elementary schools in Serang City with a two-story building. The Discrete Event Simulation (DES) approach is used when experiencing a particular event. The data taken is data on the number of students and teachers, data on evacuation times using stairs or vertical evacuation methods with a certain distribution according to actual data. There are 2 scenarios used in the simulation, namely (1) evacuation using the available stairs, and (2) evacuation using a combination of stairs for men and vertical evacuation tools for women. The evacuation system using stairs in the school building was not effective because it took 5.17 minutes, while the speed at which the fire spread was 4.30 minutes. Evacuation using scenario 2 - a combination of stairs and vertical evacuation chute - resulted in a faster evacuation time of 3 minutes. Thus, the results obtained provide a suggestion for carrying out evacuation using a combination of using stairs and using a vertical evacuation chute.

This paper presents the outcomes of a research experiment on the drying process of seaweed. There are numerous approaches to clustering data, such as partitioning and the Hierarchical Clustering Algorithm (HCA). The HCA has been implemented in binary tree structures to visualize data clustering. We conducted a comparative analysis of the four primary methodologies utilized in HCA, namely: 1) single linkage, 2) complete linkage, 3) average linkage, and 4) Ward's linkage. Clustering validation is widely recognized as a crucial issue that significantly impacts the effectiveness of clustering algorithms. Clustering validation can be identified, such as internal and external validation. Internal clustering validation, in particular, holds significant importance in the realm of data science. With this article, the main goal is to do an empirical evaluation of the traits that a representative set of internal clustering validation indices, namely Connectivity, Dunn, and Silhouette, show. In this paper, the HCA applies two distance functions between Euclidean and Manhattan distances to analyze the entanglement function and internal validity.

The increasing number of overloaded vehicles on the highway is one of the factors causing damage to flexible pavements, especially at high temperatures.

Fire in the aircraft cargo can cause dangerous damage to aircraft systems during flight. To prevent aircraft cargo fires, the fire early detection system must be built. In this work, we design and develop the fire early detection simulation system for aircraft cargo using Arduino nano microcontroller. The aircraft cargo is prone to fire due to the load of any type of goods such as dangerous goods, flammable stuff, or liquids, etc. This paper simulates the fire that occurs in artificial aircraft cargo and designs the detection and extinguisher prototypes using three kind sensors: flame, smoke, and temperature sensors combined with SMS gateway for user notification. We used SIM800L GSM module as communication tools to send and achieve data through short messages service (SMS) between security system and cellphones. Three sensors including flame, smoke, and temperature sensors were used as the warning indication to the hardware. When the sensors detect the fire and smoke, the red LED, buzzer, and vacuum pump will be on active mode, and SMS notification will be delivered immediately to the user’s cell phone. As the fire has been extinguished by the vacuum pump, the red LED, buzzer, and vacuum pump return to standby mode and the fire warning alarm system will turn off. This research is successfully developing the fire early detection simulation systems that can be applied in real aircraft cargo.

The agricultural practices carried out by the people of Aunupe Village have been going on for several generations, but the agricultural system used is not optimal because they still use a conventional farming system, namely monoculture. Apart from that, the agricultural input used is chemical fertilizer which of course does not meet the organic aspect and is not sustainable, because high chemical input and long use can damage the texture and nutrients of the soil. For this reason, community empowerment through training in the application of organic farming techniques in the form of agrosilvo conservation in an agroforestry pattern needs to be encouraged so that local communities who use land in forest areas not only obtain agricultural products but can also benefit from environmental and economic services so that they can be sustainable. Thus, the appropriate alternative that can be implemented is to utilize a non-timber farming system combined with maintaining wood trees, known as an agroforestry system, namely agrosilvo conservation. This service aims to provide knowledge and examples to the farming community regarding how to cultivate agriculture using a combination of non-timber plants and woody plants, namely with the conservation agrosilvo system. The method used is descriptive qualitative. The results of the PKMI program activities are the socialization of agro-silvoconservation activities and increased knowledge and capacity of the community in carrying out farming using the agrosilvo-conservation method.
