Rancang Bangun Tempat Sampah Pintar dengan Sistem Monitoring Berbasis Cloud dan Internet of Things (IoT) Menggunakan Metode Rule-Based

Cleaning staff sometimes experience delays in emptying trash bins because inspections are conducted manually. This method is inefficient as it can lead to trash accumulation, causing odors and potential health hazards. Therefore, this study aims to improve the efficiency of waste management. The research method used in this study includes design and development, involving needs analysis, system design, system implementation, and system testing. In this study, a trash bin monitoring system was designed using the ESP32 microcontroller, the HC-SR04 sensor to detect bin capacity, and the MQ-135 sensor to detect ammonia gas content in the trash. The system can detect the bin's capacity, the last cleaning time, and the ammonia odor in the trash. The determination of trash collection actions is carried out using a rule-based method with 100% accuracy, and notifications are sent via Telegram

Skylab Trash Airlock

The Skylab Trash Airlock (TAL) used throughout the Skylab mission to transfer trash materials that could support microbial growth from the pressurized cabin to the unpressurized waste tank is described. The TAL, which uses several basic mechanisms, was successfully operated daily for the 170 days of manned missions for a total of 637 cycles

Description of the PMAD DC test bed architecture and integration sequence

NASA-Lewis is responsible for the development, fabrication, and assembly of the electric power system (EPS) for the Space Station Freedom (SSF). The SSF power system is radically different from previous spacecraft power systems in both the size and complexity of the system. Unlike past spacecraft power system the SSF EPS will grow and be maintained on orbit and must be flexible to meet changing user power needs. The SSF power system is also unique in comparison with terrestrial power systems because it is dominated by power electronic converters which regulate and control the power. Although spacecraft historically have used power converters for regulation they typically involved only a single series regulating element. The SSF EPS involves multiple regulating elements, two or more in series, prior to the load. These unique system features required the construction of a testbed which would allow the development of spacecraft power system technology. A description is provided of the Power Management and Distribution (PMAD) DC Testbed which was assembled to support the design and early evaluation of the SSF EPS. A description of the integration process used in the assembly sequence is also given along with a description of the support facility

Addendum to the Inventory of Stored Grain Insects in Michigan

Additional species of stored grain insects have been found in Michigan since the inventory of such pests was published (Ruppel 1977). The additional species were primarily found through a study of insects in county elevators (Russell 1980) and through examinations of infested grains submitted for identification. The names of these insects are given in Table 1. The brown spider beetle and murmidius beetle were found in infested small grains, the European grain moth was found in stored soybeans and in elevator trash. and the others were found in elevator trash

Titus Phase Ceramics from the Pine Tree Farm Site (41WD51) in the Lake Fork Creek Basin, Wood County, Texas

The Pine Tree Farm site, an ancestral Caddo site occupied during the Titus phase (ca. A.D. 1430- 1680), was recorded by Bob D. Skiles in June 1977, on the basis of investigations conducted there by Skiles and James E. Bruseth, then a graduate student at Southern Methodist University, as well as work done by Skiles in 1970. The site is on a flat upland landform (400 ft. amsl) ca. 300 m northeast of Myrtle Springs Branch, a tributary to Dry Creek in the Lake Fork Creek drainage in the East Texas Pineywoods. The Goldsmith site (41WD208) is ca. 0.4 km to the east on Dry Creek, and several kilometers below the dam at Lake Quitman. The Dry Creek drainage basin, as well as the Caney Creek arm of Lake Fork Reservoir, have clusters of Late Caddo period Titus phase sites. The main known feature at the site was a large trash midden or midden mound that was ca. 20 x 22 m in size and approximately 35 cm in thickness. The midden deposits contained many Caddo ceramic vessel sherds, animal bones, mussel shell, charcoal and other charred plant remains (hickory nut shells), and ash deposits. Most of the trash midden was excavated in 1970, but there were intact midden deposits along the western and southern part of the trash midden, and in June 1977, several small units were excavated by Skiles and Bruseth in those areas. The ancestral Caddo ceramics discussed herein come from Units 2-4 in the southern part of the trash midden, but are not all of the sherds that were recovered in that work

Program Inovasi Pengelolaan Sampah Di Kota Malang

: The Innovation Management Trash Program in Malang City. Trash problem in Malang City caused by the more trash source that emerge in Malang City. Therefore, trash management innovation is necessary to cope with trash problem that occurs. This research use descriptive qualitative research method. This research result shows that trash management innovation of more emerge from citizen. The innovation strategy of trash management by DKP is cooperating with environmental activist to develop and invite the environmental activists to socialisation. The effectiveness of trash management policy is effective but still not optimal enough because of many factor. The impact of management there is awareness from citizen, additional income for the citizen and achieved trophy Adipura

Kinerja Unit Pemotong Serasah Tebu Tipe Reel

The problem of sugarcane trash after harvesting is experienced by the world's sugarcane plantations, including those in Indonesia. Large amount of sugarcane trash left in the field makes difficulties in soil management and plant maintenance. Current practice done by the sugarcane plantations was “burning before soil tillage”. However, the practice of burning cause unwanted impact to the environment and human health. Meanwhile, sugarcane trash still rich of nutrients for the land. The trash size is still long so that it should be reduced to improve composting process. The prototype was tested on 4 levels of reel rotational speeds and 4 levels of trash densities. During the tests, cutting torque and rotational speed of the reel were measured using a torque-meter and a digital tachometer. The prototype chopped up sugarcane trash of about 1.7 - 3.2 cm length. Higher trash density caused a higher cutting torque and cutting power, while higher rotational speed caused a lower cutting torque and a higher cutting power. The highest cutting torque was 4.03 kg.m, when chopped sugarcane trash of 32 kg/m3 in trash density on 400 rotational speed. Increasing the rotational speed caused a shorter trash size. Keyword: cutting power, rotational speeds, sugarcane trash, cutting torque &nbsp

What a waste: the generation and disposal of trash imposes costs on society and the environment: should we be doing more?
