Published: December 2019

Abstract
Non-resonant vibration energy harvesters (VEHs) attract much attention for the excellent performance in scavenging ambient low-frequency and broadband vibrations. In this paper, effects of the mild steel sheets, thicknesses of the magnets and coils, wire diameter of coils, and inner dimension of the coils on the outputs of a non-resonant electromagnetic vibration energy harvester (EMVEH) were simulated and the optimized geometries was obtained. Numerical simulations show that the mild steel sheets can enlarge the magnetic flux density about 25.0%, agreeing well with the experimental result that the output voltage increased about 29.3%. Under a base excitation of 0.3 g (where 1g = 9.8 m s−2) at 8.3 Hz, the RMS voltage across a 10.4 kΩ resistor of an EMVEH prototype, with the inner volume of 76.26 cm3, is about 15.53 V. The power density is about 304 µW cm−3, about 18.7% higher than the previous device.

Published: December 2019

Abstract
This paper reports the heating performance of the previously reported 4th generation shoe-insole-based hydraulic electromagnetic energy harvester (HEEH) [1] in connection with a micromachined polysilicon heater & a commercial copper heater [2]. The HEEH produced 455.77mW of power by using a 4-channel configuration under an actuation frequency of 3Hz. It was integrated with two types of heaters to produce temperature rises of 2.0 & 3.2°C and the heating rates of 12.0 & 1.6°C/min, respectively, from polysilicon (0.15×0.1mm2, 6.05e−6s of the thermal time constant) and copper heaters (78×28mm2, 8.31s of the thermal time constant). Such heating performance of the HEEH is the 1st results of its kind by energy harvester [3, 4, 5].

Published: December 2019

Abstract
This paper focuses on the systematic comparison of different basic structures for electromagnetic energy harvester to increase the power density of the converters. The goal is to select the optimal basic structure depending on the specific requirements. To achieve this, an automated design methodology was developed and implemented in MATLAB®. The systematic comparison and automation allows a cost-effective design of adapted energy harvesters for application-specific requirements. In studies, the influence of different boundary conditions on the evaluation of basic structures was investigated. It can be shown that none of the structures always delivers the highest output power.
An Umbrella-Shaped Topology for Broadband MEMS Piezoelectric Vibration Energy Harvesting
Authors: Jia Yu , Du Sijun , Seshia Ashwin A. 
Published: December 2019

Abstract
While cantilever topologies offer high power responsiveness for MEMS vibration energy harvesting (VEH), they are less robust than multiply clamped or membrane topologies. This paper attempts to address this topological optimisation dilemma by attempting to achieve both high power density and robustness. The proposed umbrella-shaped topology constituents of a single central anchor while the membrane area extends outwards and is further enclosed by a ring of proof mass. Implemented on a 0.5 µm AlN on 10 µm doped Si process, a fabricated device (121 mm2 die area) recorded a peak power of 173 µW (1798 Hz and 0.56 g). The normalised power density compares favourably against the state-of-the-art cantilever piezoelectric MEMS VEH, while not sacrificing robustness. Furthermore, this device offers a broadband response, and it has experimentally demonstrated over 3 times higher band-limited noise induced power density than a cantilevered harvester fabricated using the same process.

Published: December 2019

Abstract
We present an omnidirectional energy harvester with lowest resonance mode at 14.85 Hz. The geometry is designed as a spiral shaped, 500 μm thick PZT lateral bimorph to achieve a low resonance frequency while minimizing the area required. The resonance modes and frequencies of the energy harvester are investigated with COMSOL eigenfrequency study. The resonance modes of translation in x, y, z, and rotation around x, y, and z have resonance frequencies at 23.4, 22.9, 14.9, 34.0, 33.6, and 25.5 Hz, respectively. Multiple resonance modes widen bandwidth and enable harvesting energy from all directions. The energy harvester is mounted inside a 3D printed package that can be worn on a human wrist. The design of the package mimics the approximate size of a typical smartwatch, and the motion from walking is along the most sensitive axes of the harvester. It produces an output of 900 mV peak-to-peak for an optimum load of 1.8 megaohms and provided 0.45 microwatts. The output voltage is high enough to charge a battery through commercial diodes.

Authors: Paosangthong W , Torah R , Beeby S 
Published: December 2019

Abstract
This paper reports a novel design of textile-based triboelectric nanogenerator (TENG) with alternate grated strips of positive and negative triboelectric material operating in freestanding triboelectric-layer mode (pnG-TENG). Whereas most grating-structured TENGs operating in a freestanding triboelectric-layer mode comprise gratings of one type of triboelectric material separated by air gaps, this design presents a replacement of the air gaps by another triboelectric material with the opposite polarity to the existing triboelectric material. The pnG-TENG with 10 gratings of PTFE and nylon fabric delivers an open-circuit voltage of 250 V, a short-circuit current of 5.94 µA and a maximum peak power of 600 µW at a load resistance of ueoµΩ and a mechanical oscillation of 2 Hz. This corresponds to a maximum power density of 186 mW/m2, which is 1.73 and 2.20 times greater than the power generated by the TENG with single triboelectric material and the TENG with no grating, respectively.

Authors: Töreyin Hakan 
Published: December 2019

Abstract
Unobtrusive health monitoring applications necessitate accurate, real-time, and energy-efficient computation of health-related parameters. Two important parameters for cardiovascular and cardiac autonomic health assessment are heart rate (HR) and heart rate variability (HRV). In this paper, an energy-efficient mixed-signal processor ASIC for real-time monitoring of HR and NN50, a well-established HRV score for parasympathetic activity assessment, is presented. The proposed ASIC, designed in a 0.5 μm CMOS technology, detects R-waves of ECG signals and compares successive R-R intervals to identify the NN50 events in real-time. Post-layout simulation results using ECG signals of four recordings from the MIT-BIH arrhythmia database are compared with DSP calculations on MATLAB. Based on simulation results, the processor detects R-waves with an average accuracy of 99.1%, and NN50 events with average sensitivity and positive predictive values of 94.7% and 96.9%, respectively. The processor consumes 70 nA when supplied by ±1.6 V.

Published: December 2019

Abstract
Recently, different kinds of nonlinear energy harvesters in rotation environments were designed to achieve high-efficiency broadband energy harvester for low-level excitations. However, a mathematical model of the multi-stable energy harvester in rotation motion is not complete, and its dynamic performance remains experimentally uninvestigated due to the difficulty of the sensor layout in rotation motion. Based on these issues, in this paper, a multi-stable energy harvester used in rotation motion is proposed and a related mathematical model has been processed by Lagrangian equation to describe the dynamic performance and the output power of the harvester. Additionally, corresponding experiments between the bi-stable energy harvester (BEH) and the tri-stable energy harvester (TEH) are carried out to validate their performance under different rotation speeds. The experimental results demonstrate that the TEH can obtain high-efficiency energy harvesting performance in low rotation speed than the BEH.

Abstract
The aim of this study was to explore phosphate solubilizing bacteria in mangrove forest at Teluk Naga, Tangerang district, Banten. To collect samples, random sampling was applied. Bacteria were isolated by Pikovskaya media, using pour plate method. Nineteen isolates collected from soil demonstrated a potency to solubilize phosphate. Six isolates showed high phosphate solubilization activity from calculation of dissolution index. They were identified morpho-physiologically and biochemically as Pseudomonas (isolate R22 and A17), Klebsiella (A11, A14, A18, and A38), Agromyces (A13), Bacillus (A33 and A37), Azomonas (A15), and Enterobacter (A31 and A32). These bacteria were found in the rhizosphere of mangrove forests which consist of Avicennia and Rhizophora mangroves. These bacteria are known to have the ability to increase the availability of phosphate in the soil. This ability is one of the capabilities of the potential growth of promoting bacteria (PGPR or Plant Growth Promoting Rhizobacteria).

This research studied the effect of temperature and drying time in making “Indigenous Yeast Mold” dried culture using tray drier. There are 2 dried culture, names AC and CC. AC consists of 3 mold and 1 yeast strains, while CC consists of 7 mold and 3 yeast strains. The temperature of drying used were 40°C and 50°C and the drying time were 0, 1.5, 3, 4.5, and 6 hours. The results showed that the quality of dried cultures AC and CC were influenced by the drying times and temperatures. The water content, viability of microorganisms, Aw, and pH value decreased with the increasing of drying time and temperature. The drying time at the temperature of 40°C affected the water content and water activity of AC and CC dried culture significantly. While the drying time at the temperature of 50°C affected the moisture content, water activity, viability of microorganisms, and pH value of AC and CC dried culture significantly. The desired water content in dried culture is 10% (wb) or 11.1 (db). To reach the water content of 10%, at the drying temperature of 40 °C, the AC dried culture required 4.46 hours, while CC required 4.44 hours. Meanwhile, at the drying temperature of 50 °C, the AC dried culture took 3.46 hours, while CC required 3.33 hours. Drying could be done at 50 °C without changing the quality of the dried culture.

Published: December 2019

Abstract
The intercropping system with the right dose of phosphorus will show higher yields than the monoculture planting system. The study was carried out with the aim of: (i) comparing crop yields between intercropping and monoculture planting systems, (ii) comparing the efficiency of land use of each planting system, and (iii) phosphorus doses which provide the highest yield for each cropping system. The study was conducted at the Experimental Garden of the Faculty of Agriculture, University of Sultan Ageng Tirtayasa Cikuya Karang Kitri District Serang, starting from April to July 2019. The experiment used a factorial randomized block design. The first factor is the planting system consisting of three levels, namely the system of soybean monoculture planting, maize monoculture planting system, and intercropping system of soybean+corn. The second factor is the dose of phosphorus fertilizer consisting of two levels, namely 25 kg.ha−1 and 100 kg.ha−1. Each treatment combination was repeated three times. To find out the purpose of the study used the Land Equity Ratio (LER) indicator and Variant Analysis of observational data which included: plant height, number of leaves, weight per plant, crop weight per plot and seed dry weight. The plant growth with corn monoculture is better than intercropping system. The yield of plants with intercropping systems is higher than that of monoculture systems. Plant yields in both cropping systems (intercropping and monoculture) were higher by giving phosphorus doses of 100 kg.ha−1 compared to 25 kg.ha−1.

Elephant grass, rice straw and maize silage as feeds: a dynamic modelling approach on their degradation kinetics
Authors: Jayanegara A , Ridla M , Laconi E B , Nahrowi  
Published: December 2019

Abstract
This study aimed to evaluate nutritive value of elephant grass, rice straw and maize silage by using a dynamic modelling approach. Data on dry matter (DM) degradation characteristics were compiled, i.e., soluble (S), degradable (D) and undegradable (U) fractions, and rate of degradation of the degradable fraction (kd). Each of the S, D or U fraction was assumed to have a specific rate of passage (kp). The S, D and U fractions are dynamically changed over time. Degraded S and D fractions form a pool namely cumulative S and D (CSD) and it dynamically increases over time. Integration of all the dynamic models was performed in Vensim software version 7.3.5 using the Euler method. Results revealed that soluble fraction present in elephant grass, rice straw and maize silage disappeared within early hours in the rumen. The degradable fraction of maize silage was degraded more rapidly than that of elephant grass and rice straw. Maize silage had the highest potential CSD as compared to those of elephant grass and rice straw. It can be concluded that, based on the dynamic modelling approach, maize silage has higher nutritive value for ruminant livestock, followed by elephant grass and then rice straw.

Authors: Yulistiani D , Puastuti W , Sajimin  
Published: December 2019

Abstract
Supplementation of fermentable carbohydrate in crop by product-based diet is expected to improve the fermentability and reduced methane production. The study evaluated supplementation of various fermentable carbohydrate in sorghum straw-gliricidia mixture basal diet. Sorghum straw-gliricidia mixture was supplemented either with ground corn grain, rice bran or sorghum grain at 10% of DM basal diet. Treatment diets evaluated were: Sorghum + gliricidia leaf meal (Control); Control + 10% ground corn grain (Corn grain); Control + 10% rice bran (Rice bran); Control + 10% sorghum grain (Sorghum). Sorghum straw was chopped and ground then mixed with gliricidia leaf meal at ratio 60:40% DM. The sample was incubated for 48 hours, gas production was recorded at 4, 8,12, 16, 24, 36 and 48 hours. Rumen fluid for medium incubation was collected from sheep fed elephant grass basal diet. Supplementation of rice bran lowered (P<0.05) gas production from insoluble fraction of the diet compared to maize. Rice bran and sorghum decreased gas production at 48 h incubation compared to control (P<0.05). Sorghum supplementation decreased CH4 production. It can be concluded that fermentable carbohydrate supplementation from sorghum grain to sorghum straw-gliricidia mixture reduced percentage of methane production.
