Abstract
Measurement is a critical element in the instrumentation and control systems in the industry, especially in the process industry. The analysis can be made in various ways and methods, one who is designing a monitoring system. The design of this monitoring system can be realized as a simulation through similar visualization with industrial monitoring systems. This paper has developed and applied fluids level monitoring systems based on Zigbee to transmit and receive data wirelessly. The system design is divided into two parts. The first one is plant design and Human Machine Interface (HMI), the system that is applied in designing measurement systems fluid level. The design and application of HMI systems use Visual Basic as the user interface with the plant. In this plant, ATmega16 is being used for the system controller and MPX2010DP sensor, which was chosen to measuring the level of fluids. This sensor is selected because this sensor uses the principle of differential pressure making it easier to use. Sending and receiving data from the PC to the plant runs very well using Local Area Network (LAN). The maximum range is 30m for indoors and 90m for outdoors.

Abstract
The increase in population every year makes more and more owners of motorized vehicles and cars resulting in full access to the highway, not only the highway that experiences density while the bridge is one of the factors of density due to the number of motorized vehicles and cars that pass not only at a certain time the bridge will be congested and experience enough vibrations because the load carried by the bridge is different, the greater the load held by the bridge, the more the bridge vibrates, therefore the writer will make an instrument using a geophone sensor that can measure how much vibration on the bridge and analyze how strong concrete works on the bridge which often occurs density, with the elastomer or rubber pads used between abutments with the placement of the elastomer feeding road will reduce vibrations that occur due to the burden carried by the bridge. This tool will use the main components in the form of geophone sensors. Geophone converts ground motion into voltage, Geophone is a transducer of ground movement that is very sensitive. A geophone converts seismic energy, or vibration, into an electric voltage that can be measured accurately. In this study, it was found that geophone sensors can find out the amount of voltage and deflection that occurs when a vehicle crosses the bridge, to process data in this system using a microcontroller in the form of Arduino Uno and displayed in excel data to facilitate data collection. From this study it can be concluded with a maximum deflection of 0.3 cm or 0.003 meters at a time of 1045kg, meanwhile when a vehicle load of 2 tons to 10 tons will occur a maximum deflection of up to 2 cm on the Cilampeni Bridge and on the Kopo Toll Bridge.

Abstract
Hermetia illucens larvae or known as maggot contains considerable amount of oil in its body. This experiment aimed to evaluate the use of maggot oil as a feed supplement for reducing methanogenesis of rumen microbial culture in vitro. The oil was supplemented into a feed substrate that consisted of forage: concentrate mixture (3:2 w/w). Supplementation of the oil was performed at different levels, i.e., 0, 1, 2, 3, 4 and 5% from substrate dry matter. All incubation bottles were tightly closed and incubated for 24 h in a water bath that maintained at 39oC. Results revealed that maggot oil at 4 and 5% supplementation level was able to reduce methane emission by 20.7 and 26.9% (P<0.05) in comparison to control, respectively. However, its supplementation at 3% or lower did not alter the methane emission. The organic matter digestibility parameter was linearly reduced with increasing level of maggot oil supplementation (P<0.05), but volatile fatty acid concentration was not affected. In contrast to our expectation, maggot oil at 3 to 5% increased log protozoa population and ammonia concentration than those of control (P<0.05). In conclusion, maggot oil may serve as a promising supplement for mitigating ruminal methanogenesis and the effect is dose-dependent.

Abstract
Wheat plants can grow and produce well on the island of Lombok, ranging from highlands to lowlands around 400 m above sea level, and have opportunities for further development. This adaptation effort needs to be followed by development of cultivation technology, including proper irrigation. Irrigation is a fundamental factor in achieving maximum yields in a crop land. Wheat crop does not require a large amount of irrigation as rice plants, but it is not yet known which growth periods are critical to the water requirements for wheat plants grown on Lombok Island. This study aims to determine the effect of water stress at different growth phases of wheat on the growth and yield of wheat plants. This research was conducted using the Experimental Method in a greenhouse, with 9 water stress treatments at different phases. The treatment of water stress at different period of plant development does not show a different effect on plant growth and development. However, it significantly reduces yield and yield components. The critical period of water requirements for wheat plants occurs when the plants reach the generative phase; plants experience pressure in grain production, especially when water stress occurs in the phases of heading and flowering (anthesis). Stress in the booting and milk-development phases also experiences reduction on grain production, even at the lower levels.

Abstract
Constraints that can affect the occurrence of induction and flowering development of Siamese citrus plants are endogenous and exogenous factors. Exogenous factors include microclimate. Microclimate, especially extreme humidity, is one of the factors that can determine the physiological process of flowering of Siamese citrus plants. Siam oranges require 6-9 wet months (rainy season) and 3-6 dry months (dry) and need enough water especially in July-August (dry season). The purpose of this study was to examine and determine the role of microclimate on the phenology of flowering Siam oranges in Badung, Bangli and Gianyar. The assessment method was observed in citrus centers from 2014 to August 2018. The results showed high rainfall occurring throughout 2014, a flowering phenology disorder that had previously flowered Siamese citrus plants 1 to 3 times a year to 4 to 6 times a year. The number of flowering periods is not supported by the number of flowers formed because the flower miscarried before the fruit-set formed, the height of the deciduous flower is supported by the large number of leaves formed at the location of the garden whose height is less than 1000 meters above sea level. Location of citrus orchards which applies an integrated management system to. New potentials are good for cultivating conjoined oranges, namely dry land or dry fields and sandy soil when compared to oranges planted in faddy fields.

Published: March 2021

Abstract
The availability and the residue of phosphate in soil are influenced by the addition of phosphorus (P) fertilizer and its uptake by plant. The addition of P fertilizer also commonly affects the plant yield. This research is aimed to assess the effect of chemical fertilizer and bioorganic-phosphate on the P-available and P-residue in soil, P-uptake by plant, and the yield of soybean. Field experiment was carried out in a Vertisol of South Lombok, Indonesia, which consisted of four treatments arranged in a randomized complete block design and replicated five times. The four treatments were P0 = control, P1 = bioorganic-phosphate + 125 kg PHONSKA ha−1, P2 = bioorganic-phosphate + 187.5 kg PHONSKA ha−1, and P3 = 250 kg PHONSKA ha−1. The P2 treatment resulted the highest P-available and P-residue in soil, the highest P-uptake by plant, and the highest yield of soybean. Meanwhile, the effect P1 and P3 on all parameters were not significantly different. There is a strong positive correlation (r = 0.97) between P-uptake by plant and the yield of soybean. As the P2 treatment produced the highest yield of soybean, and the yield at the P1 is relatively the same as P3, this indicates that the application of bioorganic-phosphate can reduce the dose of chemical fertilizer by up to 50%.

Published: March 2021

AbstractThe 3D distribution of hydraulic conductivity in the unconfined aquifer is needed to understand the interaction between groundwater and Citarum River, which may relate to water contamination and flooding. In this study, it was estimated using the geostatistical method. The data used are the hydraulic conductivity parameter from thirteen large-diameter dug wells determined using the slug test method. Further analysis was conducted using groundwater and Citarum River physical parameters, i.e. total dissolved solids, pH, and temperature. The results show that the hydraulic conductivity of the unconfined aquifer in the Upper Citarum River ranges from 8.34 x 10−7to 2.19 x 10−5m/s. The area with relatively high hydraulic conductivity, i.e. Ciparay and Solokan Jeruk Sub-districts, will have a greater possibility of groundwater or river water contamination depending on their interaction. Meanwhile, the area with relatively flat topography and low hydraulic conductivity, i.e. Majalaya and Baleendah Sub-districts, will be more susceptible to flood. Therefore, the mitigation of water contamination and flooding in the Upper Citarum River should consider the 3D hydraulic conductivity distribution, e.g. by monitoring the groundwater quality in some dug wells located in high hydraulic conductivity area and installing recharge or injection well to eliminate the artificial runoff.

Published: March 2021

Abstract
Indonesia is a tropical country that has an abundance of flora. Tamarind or Tamarindus indica is one of the most famous trees and fruit in Indonesia. Now, these plant wastes are starting to be processed to be taken by the artisans to be made into powder or powdered tamarind seeds (Gutta Tamarind). Gutta tamarind becomes a substitute for wax or clay used in the batik process. Gutta tamarind is often referred to as cold batik because it does not use a heater like a process commonly found when using clay or better known as batik gutta tamarind. Gutta Tamarind’s exploration as a technique in painting aims to make technical innovations and this tamarind gutta can be used as an aesthetic element in a painting. The research method will be carried out by developing techniques in painting through an exploration of the gutta tamarind medium as a color barrier and showing various artistic breakthroughs generated by the variety of research and exploration of its constituent materials into paintings as a substitute medium for brush strokes. It is hoped that the results of this study will add insight into the use of environmentally friendly plant waste and produce paintings with aesthetic elements and new artistic breakthroughs.
Construction map model of water location permits in the implementation of licensing for marine space utilization
Authors: Astor Y 
Published: March 2021

Abstract
Based on the results of the identification and inventory of existing laws and regulations, there are 12 ministries carrying out sea space utilization activities consisting of sea surface space, sea column space, and seabed space. The 3-dimensional marine space is influenced by dynamic characteristics of the sea which makes recording and administering Marine Space Utilization Location Permits more difficult than recording and administering permits on land. This study makes a Water Location Permit Map model that describes the location of marine space utilization objects and their utilization boundaries. Water Location Permit Map is made using a coastal environment map and a marine environment map from the Geospatial Information Agency, as well as a zoning map of the coastal area from the Ministry of Marine Affairs and Fisheries. The results obtained that the Water Location Permit Map that was made using existing maps cannot yet describe the object of sea space utilization. A larger input map scale is needed, one of which is by taking remote sensing satellite image. Visualization of sea space in 3 dimensions can be displayed by classifying Location Permit Maps into 3 layers based on different sea depths namely sea level, sea column, and seabed.

Published: March 2021

Abstract
The current river’s condition in Indonesia has decreased in water quality, especially in big cities. The rivers have been polluted by domestic and non-domestic waste. Therefore, the Government has to monitor rivers water quality periodically to see its condition of the rivers water quality. Utilization of the information technology in river quality monitoring is one of the less resources consumption. This study aims to investigate the development of information technology in big cities in order to support to monitoring river water quality. This study is carried out with literature and references reviews as well as expert interviews. The results showed that the information technology has not yet been applied to monitor rivers in Indonesia. Several efforts have been started, but the systems are still incomplete. Although smart water program has been adopted in Indonesia, it shows problem in its sustainability due to financial difficulty, devices durability, and connection instability. To overcome these obstacles, it is recommended that government should have strong inter-collaboration between divisions and partnership with other institutions.
