Abstract

Severe effects of the mercury use on health as an amalgam material have required an alternative material in order to eliminate it from amalgam composition. This research was conducted to analyze the physical properties and compressibility of ZnO nanopowder as an alternative amalgam material. The physical properties including morphology, dimensions, and the atomic ratio were analyzed by SEM, XRD-XRF and EDX. Further, the compressibility was conducted by using hydraulic press machine. The results showed that ZnO has particle size of 14.34 nm with morphology classified as nanorods. In the compressibility test, both the variation of compression loadings and holding time have brought an effect on the significant increase of ZnO nanopowder density.

Abstract

The effects of MnFe2O4 nanocatalyst addition toward HDPE plastic waste pyrolysis have been investigated by performing experiments on METTLER TOLEDE TGA DSC1 Simultaneous Thermal Analyzer at heating rates of 10oC/min by nitrogen and temperatures range from room temperature to 1000oC. The results of pyrolysis showed that the main polymer components of HDPE plastic waste, both, with and without MnFe2O4 nanocatalyst addition degraded in one stage. The MnFe2O4 nanocatalyst addition increases the maximum mass loss rate of HDPE plastic waste pyrolysis, however, it increase the degradation of the initial temperature.

Abstract

This study has reported the effects of different formulation ratio between recycled high density polyethylene (r-HDPE) and recycled polypropylene (r-PP) into the resulted mechanical, thermal and morphological properties of r-HDPE/r-PP polymeric blends. About five (5) different formulation ratio of r-HDPE/r-PP have been prepared and tested. The best combination ratio between r-HDPE and r-PP was determined in this work. It was found that the 70/30 wt.% of r-HDPE/r-PP blend possessed an outstanding mechanical and physical strength. About 59.80% and 2.30% of positive improvement in comparison to 0/100 wt.% of r-HDPE/r-PP was achieved for both of tensile strength and hardness, respectively. Interestingly, for 70/30 wt.% of r-HDPE/r-PP blend had also experienced major increased in their elongation at break up to 473%. The fracture morphological behavior of the tested samples that were observed via SEM observation, had established the interaction between the structure and properties of produced r-HDPE/r-PP blends, especially on the miscibility state between the r-HDPE and r-PP phases. Thermal evaluation by using the DSC had confirmed the partial miscibility state due to dominant peak shifting at 120 - 140°C and obvious melting peak reduction pattern. Overall, from this study, it was found that the blending between r-HDPE and r-PP into r-HDPE/r-PP blends are feasible to improve the properties of primary phase.

Abstract

In this study, the application of nanotechnology was applied in the dentistry field, especially in the innovation of dental amalgam material. To date, mercury (Hg) has been used widely as dental amalgam material with consideration of the cheap price, ease of use, and good mechanical strength. However, last few years, many problems have been faced in the dentistry field due to the use of mercury. Hence, new material is needed as an innovation to eliminate the mercury from dental amalgam composition. This research was conducted to analyze the physical properties and compressive strength of zinc oxide (ZnO) nanopowder as a potential dental amalgam material. The physical properties such as morphology and dimensions were analyzed by SEM and XRD. Further, the compression test was conducted by using hydraulic press machine. The results showed that the ZnO nanopowder analyzed has the particle size of 14.34 nm with the morphology classified as nanorods type. On the compression load of 500 kg, the average of ZnO green density is 3.170 g/cm3. This value experienced the increase of 4.763% when the load was set to 1000 kg, and 7.539% at 2000 kg. The dwelling time also took the same effect. At 30 seconds, the average of ZnO green density is 3.260 g/cm3. This value experienced the increase of 0.583% at 60 seconds and 3.098% at 90 seconds.

Kata kunci—Teknologi, I-Bite, Internet of Things (IoT), pakan ikan, efisiensi, produksi  AbstractFeed is the biggest component in the consumption of fish farming. Poor feeding results in increased Feed Conversion Ratio (FCR), decreased water quality, and fish mortality. Based on the problems faced by partners and current technological developments, this article on the results of community service proposes an Appropriate Technology I-Bite system that uses IoT to make it easier to apply. Users can set the amount of feed to be given, the duration of feeding, the distance of the stocking area, the feeding schedule according to the needs, and the data cycle of feeding via email. The purpose of this community service is to overcome difficulties in providing the right amount of feed in an even area with a predetermined schedule and provide socialization related to how to operate, assemble and install instruments. The method of implementing this service is by socializing and testing the performance of the instrument. The test results show that the instrument can spread the feed as far as 14m with a discharge of 4kg / minute at an angle of 110 '. From the results of these tests, it can be concluded that I-Bite can be a partner solution in terms of feeding using the proposed instruments which can be a solution to the problems experienced by partners, especially making it easier to feed.Keywords—Technology, I-Bite, Internet of Things (IoT), fish feed, efficiency, production

Abstract

This paper investigates the effect of using metakaolin Artificial Lightweight Aggre­gates (ALWA) as a substitute for coarse aggregates to produce structural lightweight concrete. A combination of 10M NaOH solution and sodium silicate solution was used as alkali activator. The ratio between the metakaolin binder and the alkali activator used in producing metakaolin ALWA is 48%:52%, by mass. It is shown that metakaolin ALWA has higher abrasion and water absorption, and lower bulk density values compared to normal aggregates. To determine the effect of using metakaolin ALWA as coarse aggregates in concrete, three variations of ALWA dosages were used, i.e. 0%, 50%, and 100% of the total coarse aggregates, by volume. The results show that the compressive strength of concrete decreased along with the increase of ALWA content in the mixture. However, concrete using 100% ALWA as coarse aggregates meets the requirements of compressive strength and density of structural light weight concrete.

Abstract

Pengelasan busur listrik elektroda terbungkus cocok digunakan untuk pelat-pelat datar. Namun untuk benda pejal sulit untuk dilakukan, apabila digunakan untuk benda pejal, maka, hasilnya kurang baik. Salah satu solusi untuk mengelas benda pejal yaitu menggunakan pengelasan gesek. Tujuan penelitian ini adalah untuk mengetahui kekuatan tarik hasil pengelasan gesek (friction welding) dengan variasi kecepatan putar, durasi gesek dan tekanan serta mengetahui bagaimana struktur mikro hasil pengelasan gesek (friction welding). Metode yang digunakan dalam penelitian ini menggunakan model one-shot case study dan analisis deskriptif. Analisis deskriptif meliputi hasil uji tarik dan struktur mikro hasil pengelasan gesek. Berdasarkan hasil penelitian yang dilakukan, nilai kekuatan tarik yang paling tinggi dihasilkan pada variasi kecepatan putar 2850 Rpm, durasi gesek 60 detik pada tekanan 8 Mpa. Sedangkan untuk hasil kekuatan tarik yang paling rendah yaitu dihasilkan pada variasi kecepatan putar 2850 Rpm, durasi gesek 80 detik pada tekanan 8 Mpa. Hasil foto mikro menunjukan bahwa tidak ada perubahan fase pada hasil pengelasan gesek hanya terjadi penghalusan partikel Mg2Si pada daerah Zpd dan Zpl, sedangkan pada daerah Zud memiliki bentuk partikel Mg2Si yang sama dengan spesimen tanpa perlakuan.
