Published: January 2020

Magetan Regency is one of the leading fruit production centers (Pamelo Oranges) and vegetables in East Java. Production of Pamelo orange as a superior product of Magetan regency, during the last 10 years tends to decrease both in terms of quantity and quality. This is as a result of fruit fly pest attack is quite massive and viral; as well as vegetable crops that still depends on pesticide and chemical fertilizers. Quantity and quality of fruit and vegetable products are still not optimal because: 1). There are still pests and diseases that can not be controlled in an environmentally friendly manner, 2) The cultivation of pamelo and vegetable plants in Magetan regency has not been fully applied organic fertilizer intake, 3). Gardening irrigation technology still relies on rain water and semi-technical irrigation. The objective of the action research through Community Partnership Program (CPP) is to provide a touch of science and technology that is expected to accelerate the creative economic activities of the community by providing skills training based on organic materials including: 1. The utilization of yard land by planting vegetables; 2. The production soil enhancer; 3. Production of urine-based biopesticide ; 4. Simple book keeping practice in small-medium scale agriculture, and 5. Production of Pamelo orange-based food. The methods used in facilitating the improvement of skills of farmers and dairy farmers joined in micro small and medium enterprises including lecture, field practice and mentoring. The result of activities is expected to be able to: a). improve farmers skills in good plant care through integrated pest and disease control and organic based fertilization through fertigation. b). Make environmentally friendly fertilizers and pesticides independently. c). Increasing the production and quality of agricultural products. d). Innovative organic biofertilizers products.

The ground-mounted solar farms are the most common type of Thailand solar power plant. Presently, the area under the solar panels in Thailand had not been utilized. This work was to investigate a suitable configuration for space utilization under the PV panels which could promote power production. The effect of space utilization was investigated for 3 configurations: a water pond, chili cultivation, and a grass plantation. Under the first PV string, the pond sizing 2.4 × 15 meter was created. Under the 2nd PV string, 60 chilies samples were planted. Moreover, the grass was planted under the third string. The intensity of solar radiation (W/m2), temperature, voltage and current of solar panels were also monitoring. The impact of all configurations on the power generation was evaluated and compared with a control. Results indicated that the space utilization of the first string (the pond) and of the second string (the chili cultivation) generated electricity at 1.6 kW. Both configurations could generate more power than control. The pond and the vegetable plantation were suitable configurations for promoting power production.

Published: January 2020

This research aims to perform the techno-economic feasibility of the applied hybrid biomass stove to produce hot water for serving Child Development Center (CDC) in Omkoi District, Chiang Mai, Thailand. The hot water generated from the stove could help to decrease LPG usage and enhance household economics. Many activities in CDC (i.e., children showering during the winter season, cloth washing, and utensils cleaning among others) require hot water to prevent the contamination of harmful germs which could cause many diseases such as diarrhea in young children. Presently, Asian Development College for Community Economy and Technology, Chiang Mai Rajabhat University (adiCET) has installed the hybrid stove to the in Omkoi district. The biomass stove could generate 90 °C hot water using plant/agriculture waste as the fuel. However, the economical parameters (i.e., Payback Period, Net Present Value and Internal Rate of Return) could strengthen the technology. The results from this study could be used as one of the guidelines for policymakers to design the appropriate programs for enhancing the CDC using the waste-to-energy concept.

Authors: Sang Zangta , Sawatdeenarunat Chayanon , Suaisom Pitchaya 
Published: January 2020

Anaerobic digestion (AD) of starch wastewater for biogas production has been widely installed in Thailand for a decade. Unfortunately, this specific waste stream contains low alkalinity (Alk) and high volatile fatty acids (VFAs) which could easily lead to system instability. The appropriate monitoring indicators could help to decrease chance of reactor failure. The aim of this study is to investigate the performance of the AD system and the effect of operating parameters i.e. oxidation-reduction potential (ORP) and pH on the system in a continuous stirred tank reactor operated in semi-continuous mode at organic loading rate (OLR) of 1.0 kg COD/m3.day. The temperature was controlled at a mesophilic condition (35±2°C) for the whole experiment. The results showed that the average ORP and pH were -400 ±50 mV and 7.0 ± 0.2, respectively. The average biogas and methane yields were 0.901±0.128 NL/g VS added and 0.528±0.076 NL/g VS added, respectively. The methane composition was 58.43±4.76 %. The total COD and filtrated COD removal efficiencies were 94.75±1.42% and 97.88±0.53%, respectively. It could be concluded that at the low OLR (i.e. 1.0 kg COD/m3.day), pH and ORP was stable and fell within the recommended range for AD and indicated the stability of the system.

Published: January 2020

Mae Cham district is located only 156 kilometers from the center for Chiang Mai, but the road trip would take at least 3 hours on the meandering mountains road. The first dirt road that provides access between Mae Cham in Chiang Mai was completed in 1963. The result of the road network and access to the global market has both positive and negative impacts on the people pf Mae Cham. The access to Mae Cham has transformed the food production system in Mae Cham from being self sufficient to becoming a part of the national and international food chain. The crops on the field have changed from rice to cash crops like animal feed corn and from local vegetables to commercial crops like cabbages, to feed into the national and international food chains. The consumption of local food has been transformed as well. The local dishes remain the same, while the added ingredient such as monosodium glutamate, fish sauce, seasoning powders that have increase the chance of high blood pressure, heart disease and diabetes.

Published: January 2020

Indonesia merupakan penyumbang ketiga pasar kakao dunia. Hal ini menyebabkan limbah padat yang dihasilkan mencapai lebih dari 60% dari total produksi buah. Namun penggunaan limbah kulit buah kakao oleh petani belum optimal. Umumnya petani hanya membuang atau membenamkan saja limbah kulit buah kakao tanpa diolah terlebih dahulu menjadi pupuk organik berkualitas. Penelitian ini bertujuan untuk mengetahui: (i) Pengaruh biochar dan dekomposer dalam mempercepat proses pengomposan limbah kulit buah kakao dan memperbaiki kualitas pupuk organik, (ii) Mengetahui pengaruh penambahan Bakteri Pelarut Fosfat (BPF) ke dalam pupuk organik yang berasal dari limbah kulit buah kakao terhadap pertumbuhan bibit kakao (Theobroma cacao L.). Penelitian ini dilaksanakan mulai dari September 2014 sampai dengan Agustus 2015. Penelitian tahap pertama dilakukan dengan menggunakan rancangan faktorial 2 faktor dalam Rancangan Acak Lengkap (RAL) untuk mengevaluasi pengaruh penambahan biochar dan dekomposer terhadap percepatan proses pengomposan limbah kulit buah kakao. Perlakuan yang diteliti adalah: (i) Biochar (tanpa biochar dari bobot kering bahan pupuk organik dan biochar 10% dari bobot kering bahan pupuk organik), (ii) Dekomposer (tanpa dekomposer dan dekomposer 100 g kg-1 bahan pupuk organik dengan kerapatan ± 106 SPK ml-1). Penelitian tahap kedua menggunakan rancangan faktorial 3 faktor dalam Rancangan Acak Lengkap (RAL). Perlakuan yang diteliti adalah: (i) Jenis pupuk organik (tanpa pupuk organik, pupuk organik, pupuk organik dan biochar), (ii) Inokulan Bakteri Pelarut Fosfat (BPF), (tanpa inokulan BPF, inokulan BPF A dan inokulan BPF B), (iii) Dosis pupuk P (tanpa pupuk P, pupuk SP-36 1 g P2O5, pupuk SP-36 2 g P2O5 , dan pupuk fosfat alam 2 g P2O5 ). Hasil penelitian menunjukkan bahwa pemberian biochar dan dekomposer tidak mempercepat proses pengomposan. Pemberian biochar dan dekomposer meningkatkan kadar asam humat. Pemberian fosfat alam 2 g P2O5/2.2 kg BKM meningkatkan pertumbuhan tinggi bibit kakao. Pemberian pupuk organik dengan biochar atau tanpa biochar pada faktor perlakuan inokulan BPF A dan BPF B meningkatkan secara nyata diameter batang bibit kakao. Pemberian pupuk organik meningkatkan diameter batang, tinggi tanaman, jumlah daun bibit kakao, berat kering akar dan berat kering batang bibit kakao.

Abstract
Al4SiC4 powder was successfully synthesised at a temperature 150 °C lower than before: the use of a microwave hybrid heating method required only 3 % of the heating time compared to conventional methods. The effects of composition and processing parameters, such as temperature and dwell time on the formation process of Al4SiC4 were investigated. The results indicated that with the excess Al from 0 to 5 at.% in the composition, the amount of Al4SiC4 phase in the samples processed at 1 200 °C increased together with the decreasing amount of Al4C3 phase. Further increases in the content of Al above 5 at.% resulted in the decrease of the Al4SiC4 phase content. For a fixed composition of Al : SiC : C of 4.05 : 1 : 3, Al4SiC4 formed as a major phase together with the decrease of SiC, C, and Al4C3 phases at temperatures varying from 1 000 °C to 1 500 °C for 6 min. When the dwell time was extended to 15 min at 1 500 °C, a high-purity Al4SiC4 phase with a tiny amount of impurities could be synthesised. The as-obtained powder was mainly composed of hexagonal plate-shaped particles with a mean diameter of approximately 1 μm.
ESTIMATION OF THE MAIN GAS PIPELINE OPERATION UNDER EMERGENCY CONDITIONS OF GAS LEAKAGE
Authors: Bolonny V. T. 
Published: January 2020

The characteristics of the gas transportation system of Ukraine are presented, the emergency risks of domestic gas transportation pipeline sys­tems are established. The analysis of the accident rate of gas pipeline trans­port in Ukraine and Russia was carried out. Presented technique of deter­mining the emergency pressure in the pipeline, depending on the amount of gas losses from pipeline at the point of its leakage provides an opportunity to determine the volume of gas losses from the pipeline and to evaluate the environmental risks due to emergency situations of gas pipeline transport. This technique makes it possible to calculate the pressure at each point of pipeline under nonstationary conditions caused by changes in pressure at the beginning and at the end of the sector and the emergence of concentrated gas leakage.
Based on the results of calculations, a graph of pressure change of the oscillatory process in the gas pipeline caused by jump of pressures at the beginning and at the end of the sector, and the presence of probable lea­kages at the determined point of the trace was constructed. The linear part of the main gas pipelines is the most dangerous object, as all emergency sit­uations are associated with emergency processes of different intensity in the form of gas leakage into the environment and in fact are dangerous when system failures appear. The process and the time period for the formation of the gas pollution zone depend on the amount of gas leakage, its intensity and depth of the gas pipeline.
The filtration resistance of the soil as a porous medium, in particular its permeability, have a significant effect on the amount of gas leakage through corrosive orifice. As a result, there is a correlation between the amount of gas losses associated with the leakage, and the laws of its filtra­tion in the surrounding soil.
As a result, the effect of gas filtration process in the soil in the event of leakage from pipelines has been investigated. The graphic dependence of change in pressure of the filtration resistance of the medium and the time-changing leakage which are designed for different soil characteristics is obtained.
COMBINED STEAM AND GAS TURBINE POWER UNIT WITH MAGNETIC HYDRODYNAMIC INSERT
Authors: Kulyk M. P. 
Published: January 2020

A possible way out of the critical state of existing thermal power generation facilities of Ukrainian IPS (Integrated Power System) is seen in their refurbishment with combined steam and gas turbine power units, especially with those operating on solid fuel. Solid fuel, namely ground coal is burned according to scheme from an additional cyclone extended furnace sequentially connected to the main furnace using atmospheric air enriched with oxygen. Atmospheric air is enriched with oxygen by means of membrane air separators to the concentration of up to 40% vol.
The peculiarity of the proposed power unit is presence of a magnetic hydrodynamic insert, which is located in the additional furnace sequentially connected to the main furnace, the additional furnace is made with a double cooling jacket. Heated air and coal dust is mixed in the additional furnace inlet to form a working fluid for MHD generation. After passing the area of nets and crown electrodes, the charged particles, flying at high speed past the extracting nets, reach a collector where positive charge is accumulated. This charge is essentially the electromotive force of MHD generator, the bigger part of voltage goes on load resistance and smaller part comes to crown electrodes.
Due to the increased oxygen content, the flare temperature increases, approaching 2700-3000 0C, and due to a much smaller amount of nitrogen, formation of nitrogen oxides is decreased. This reaction is endothermic, which explains increase of the flare temperature, and therefore, increase of thermal efficiency of the furnace.
The amount of generated electricity is increased due to the work of the magnetic hydrodynamic insert, while amount of coal burned is not changed. Along with the increase of overall efficiency, the emissions of formed nitrogen oxides are decreased, which improves environmental situation in the power unit location.
