PEMBUATAN AMALGAM KANDUNGAN Cu TINGGI UNTUK TAMBAL GIGI DAN PENGARUH KANDUNGAN Hg TERHADAP NILAI KEKERASAN. Penelitian pembuatan amalgam Cu tinggi serta pengaruh kandungan Hg terhadap kekerasannya telah dilakukan. Dalam pembuatan paduan amalgam digunakan satu jenis serbuk logam, yaitu paduan Ag-16,9%, Sn-19,5%, Cu-0,2% Zn (single particle alloy) dengan ukuran serbuk 325 mesh. Variasi kandungan Hg pada batas antara 45% sampai dengan 60% berpengaruh terhadap nilai kekerasan paduan amalgam Cu tinggi. Kekerasan maksimum diperoleh pada kandungan 51% Hg sampai dengan 55% Hg. Nilai kekerasan paduan amalgam Cu tinggi ini lebih tinggi dari pada paduan amalgam Cu rendah. Hasil pengamatan struktur mikro menunjukkan bahwa peningkatan kekerasan disebabkan karena pembentukan fasa η' dan Ag-Cu didalam matriks γ1.

PREPARATION OFPOLYURETHANE MICROCAPSULE USING 1,3 PROPANEDIOLAS THE POLYOL COMPONENT. Self-healing property is the ability of a material to heal damages automatically and autonomously. Its application would be ranged from paint coating, anti corrosion coating, space-shuttle material, construction (concrete) and automotive. Extrinsic self healing requires self healing agent preembedded or incorporated into polymer matrix that would be released and close the damage in the polymer system, where the polymer itself is not healable. Healing agents are encapsulated or embedded into the material prior application. Example of monomer encapsulated to give self healing property is isophorone diisocyanate (IPDI) encapsulated in polyurethane shell. In this study, we studied the possibility of 1,3 propanediol, that can be derived from palm oil as polyol monomer for polyurethane microcapsule shell containing IPDI or stannous octoate as a self healing agent. Microcapsule in this study was prepared by interfacial polymerization technique to form IPDI monomer in polyurethane shell. FT-IR analysis show that polyurethane prepolymer produced still have unreacted isocyanate group necessary for interfacial polymerization of polyurethane. Morphological analyses of the microcapsule products show that the products have spherical shapes with smooth surface and some with wrinkled surface. The particle sizes were ranged from 40.29 to 526.80 μm.

Wetland farmers in Maos District, Cilacap Regency were originally all farmers of paddy fields, but the increasing economic need, the farmers began to shift to fish farmes (pond) because the income is hgher. However, this resulted in conflicts over the utilization of water resources for paddy fields and ponds. The research method is deskriptive, databased on interview result both to farmer of paddy field, pond farmer, water user officer and related service in Maos District, Cilacap Regency. The result showed that conflict of utilization of water resources of irrigation in Maos District between wetland farmer and fish farmer (pond) have an effect on paddy farmer production result. Rice production is not optimal because water that should be used for irrigation is reduced to the pond. Maintained capacity of the irrigation network can ensure the water requirements of farmers. The Goverment as a main authorities in management of primary irrigation network, needs to improve its capabilities especially in allocating operational and maintenance funds. To increase paddy production and the welfare of society, policies need to be done first is to increase the irrigation capacity. Keywords : conflict, paddy field, fish pond

March 2020 was the beginning of the pandemic period in Indonesia, this had an impact on many business sectors, one of which was micro, small and medium enterprises (MSMEs). This pandemic period has forced the government to limit direct interaction activities. So it takes a media transaction in order to reduce public activity in direct transactions. The design method uses the Agile SDLC which is suitable for rapid adaptation in building short-term systems. To ensure the system runs as desired, Black Box Testing and White Box Testing are carried out. The presence of an API (Application Programing Interface) with the calculation of the radius of the Haversine Formula method can detect the distance of the nearest MSME up to a radius of 1 Km. Based on research conducted using 20 samples that were tested, it resulted in an average distance difference of 0.004 from the distance of Maps. So that customers can easily find MSMEs around them and make transactions or orders online.

Vitamin C is one of the micronutrients needed in the body. The need for vitamin C can be met by consuming fruits and vegetables. Vitamins are easily damaged due to heating time. There are several methods developed to determine the content of vitamin C in food and one of them is the iodometry method. The iodometric method is considered simpler and easier to do in testing the content of vitamin C in food and beverages. The purpose of this study was to determine the effectiveness of iodine indicators in measuring the content of vitamin C in several types of packaged fruit juice drinks and original fruit juices that had been treated with different heating. From the results of testing and literature studies regarding the effect of heating time on vitamin C content in fruit juices, it shows the suitability of a decrease in vitamin C content. This shows that a simple iodometric method is quite effective in showing the results of measuring vitamin C content in samples.

Utilization of biogas sludge waste from cow dung into briquettes is an alternative to reduce the use of fossil fuels. In the manufacture of briquettes made from biogas sludge, molasses is used as an adhesive which is a by-product of a sugar factory. In this study, variable compression briquettes with variations of 10, 15, 20, and 25 mm were used and further testing was carried out on the moisture content, ash content, and calorific value of the briquettes. The effect of briquette compression on the water content of the best briquettes according to the SNI standard (less than 8%) is at 10 mm compression variation with a moisture content value of 6.03%. Meanwhile, the effect of pressing briquettes on the ash content and calorific value is still above the SNI standard and requires further study.

LPG gas leaks cause serious problems in its use, it is very vulnerable to leaks that cause LPG gas cylinders to explode and catch fire, therefore an automatic gas leak detection and monitoring system was developed. If a gas leak occurs, the sensor will immediately recognise the incident and send a notification in the form of an alarm sound and a warning notification sent to the Smartphone. This detection system is made to determine gas leaks in gas cylinder regulators using the Relatime Database method on the RTOS (Real Time Operating System) system with Fog-Cloud Computing services.
