Published: April 2022

Abstract
Reducing CO2 emission is basically simultaneous processes between suppressing the carbon (C) release and increasing C sequestration. These can be carried out by plants as they have capability to fix CO2. The objective of this study was to investigate the C stock and sequestration in dryland with two systems, namely teak tree-based agroforestry and food crop system on Saobi Island, Madura. Data were collected from three measuring plots of each system, which were determined purposively. For the agroforestry system, the employed plot was the one having relatively regular tree spacing; while for the food crop system, the plot compromised the border where the jaran trees planted. Teak tree biomass and C stock were calculated by employing allometric equations, while for food crops, undergrowth, and litter were determined by using destructive methods. Carbon stock was calculated by an allometric equation and conversion from biomass weight. The results showed that agroforestry and food crop systems produced biomass up to 11.59 and 14.97 t/ha respectively. Although the biomass of both systems was quite similar, the C stock in the agroforestry system was higher than that of the food crop system; as the agroforestry one could sequestrate CO2 as much as 2308.23 t/ha, and 20.96 t/ha in existing conditions.

Abstract
Indonesia is the fourth largest country in the world as a coffee producer. Coffee has complex chemical structure with volatile and non-volatile compounds, this composition has an important role in the distinctive coffee’s taste. Fermentation is an important stage in coffee processing, it has a direct effect on the coffee’s quality. So far, many people have done traditional fermentation relying on natural microbes in fresh coffee. The purpose of this study was to improve coffee’s quality by controlled fermentation using added yeast, thereby encouraging the sustainability of coffee production. The coffee cherries were taken from a coffee plantation in Merapi mountain area, Yogyakarta. Yeast isolates used were Saccharomyces cerevisiae and Pichia kudriavzevii. The experimental processes of fermentation were carried out on three different environmental variables, namely: fermentation in bioreactor with inoculum, fermentation in bioreactor without inoculum, and traditional fermentation in an open container. Coffee cherries were peeled by pulper machine then kept underwater for 72 hours, except for fermentation in an open container. Data logger was used to monitor the temperature changes, the moisture content, brix, PH, and color change were measured for each 24 hours during fermentation. From the data analyzed, the moisture content and brix were increased during fermentation. The result indicated that fermentation by yeast addition raised acidity in the final coffee result, this can be shown from the PH result that eventually decreased from 5.83 to 5.49 and 6.15 to 4.29, respectively. The maximum temperature for both yeast species addition was reached at a 24 to 48 hours period. The result showed that the color parameter (LAB) was elevated, except the lightness value from Pichia kudriavzevii fermentation. Result in this study revealed that the type of microorganism will determine the characteristics of the coffee produced, such as the acidity. The specific taste and aroma compound were generated during fermentation by different yeast species.

Published: April 2022

Abstract
This study aims to find out the effect of vegetable cultivation systems that are managed organically, semi-organic, and conventionally on the unstable and stable carbon fraction of Andisol soil on the north slope of Merbabu. Field research was carried out using a sampling method in 3 different farming systems, namely organic (O), semi-organic (SO), and conventional (K) and 3 soil depths, namely 0-20 cm, 20-40 cm, and 40-60 cm. The parameters measured include the physical, chemical, and biological properties of the soil. The physicochemical properties of the soil analyzed included texture, volume weight of soil, pH-H2O, pH-NaF, organic matter, cation exchange capacity, total-N, Al/Fe extracted oxalate and pyrophosphate. The carbon fractions analyzed included particulate organic matter carbon, water-soluble carbon, soil organic carbon mineralization, microbial biomass carbon, humic acid, and fulvic acid. Analysis of Variance (ANOVA) was conducted to determine the effect of farming system and soil depth on soil physicochemical properties, while the difference between the two-treatment means was analyzed by DMRT. Regression-correlation analysis was carried out to determine the close relationship between the independent and dependent variables. The results showed that the farming system and soil depth had a significant effect on soil physical and chemical properties. Parameters of soil chemical properties that significantly affect the farming system and soil depth are pH-H2O, pH NaF, organic matter, cation exchange capacity, total-N, and Al/Fe pyrophosphate extracted. Organic farming systems have an unstable and stable organic carbon fraction that is more dominant than semi-organic and conventional farming systems. Parameters of soil chemical properties such as organic matter, total organic carbon, and total-N are closely related to particulate organic matter carbon, water-soluble carbon, microbial biomass carbon, soil organic carbon mineralization, soil humic and fulvic acid. The organic farming system has been proven to improve the physical and chemical properties of the soil and increasing the availability of organic carbon fraction in Andisol soil.

Authors: Ishak L , Sarni  , Erwin  
Published: April 2022

Abstract
A poor plant residue management in the nutmeg plantation system in the Ternate Island is claimed as the major factor causing the decline of soil organic carbon (SOC), and hence the low production of nutmeg. The present study was conducted with the aim of examining the relationship between SOC and plant residue removal activity in nutmeg croplands. An interview method was used to collect data from 140 farmers about their knowledge on SOC and the models of plant residue management adopted in their cropland. A snap-shot field survey was also undertaken at 14 plantation sites to collect soil samples from the depth of 0-20 cm and 20-30cm soil layer to be analyzed. The result of interview was analyzed descriptively, whilst the soil variable data were analyzed using regression models. The findings revealed that all the respondents remove plant residue from the soil surface and burned it. About 80% of the respondents applied it four times a year, whilst the rest 20% did it twice a year. The SOC content in the soils treated with the four times residue removal practice was lower than ones with less frequency of plant residue removal, and thereby has triggered the formation of subsoil compaction.

Therefore, this study aims to analyse the semi-organic shallot value chain in order to identify constraints on production and marketing, also to assess its value chain sustainability performance, with case of marginal land in Selopamioro village, Bantul district, Yogyakarta. The research involves multi-stakeholders along the chain, including three farmer groups i.e. Lestari Mulyo, Sekar Mulyo, and Bumi Mukti. These groups have consistently developed semi-organic shallot production for the past few years, using different bulb varieties, due to their soil characteristics. Snowball sampling is applied in mapping the value chain actors, followed with survey, key informant interview within guided questionnaire, and market observations. Data analysis covers descriptive analysis, PESTEC analysis for constraint identification and improvement recommendation, while value chain sustainability performance is assessed through selected indicators of economic, social, and environment related to the study area. Results describe actors, supporters, and influencers of the existing value chain. In terms of production constraints, results identify: poor marginal land fertility, same time harvesting, discontinuous supply, impatient farming activities, women role equality in farming activities, lack of processing sources, virus contamination risk, longer seedling, and limited source for shifting fuel into electrical machineries. As marketing constraints, results identify: on farm government focus, lack of selling skill and sustainable commodity campaign, unreliable off-takers linkage, limited alternative market information, consumer price sensitivity, verbal agreement transaction, minor young farmer membership, poor e-commerce skill, weak branding effort and processing focus, and business unit unavailability at farmer group. Recommendation highlights the triple helix approach in strengthening the collaboration within the chain. Further the value chain is considered sustainable, with sustainability performance of the value chain related to Lestari Mulyo and Sekar Mulyo is good, and Bumi Mukti is moderate.

Sweet corn is a tropical plant that is widely grown by farmers in Indonesia. The sweet corn market is wide open to the retail level since it is popular for its sweet taste. It can be consumed directly for vegetables, roasted corn or steamed corn. In terms of price, sweet corn offers a higher value than field corn, thus encouraging the enthusiasm of farmers to plant sweet corn. The Center for Agrotechnology Innovation Universitas Gadjah Mada (PIAT UGM) has developed sweet corn farming using a superior seed called Bonanza Now F1, which is expected to be introduced and adopted by farmers. However, it is paramount to conduct a feasibility analysis of sweet corn farming utilizing this seed to ascertain whether the farming can benefit farmers so that it is feasible to cultivate. This study aims to (1) determine the cost and the revenue of sweet corn farming, 2) analyze the income of the sweet corn farming, and 3)determine the feasibility of the sweet corn farming. We utilize sweet corn farming data in 2020 from PIAT UGM to conduct cost-income and feasibility analyses using the R/C ratio. The results show that: 1) The cost and the revenue of sweet corn farming carried out by PIAT UGM is 8,425,649 IDR and 36,050,195 IDR per hectare, respectively, 2) The sweet corn farming generated income around 27,624,546 IDR per hectare, and 3) The value of the R/C ratio in sweet corn farming is 4.28, indicating that for every expenditure of 1.00 IDR, the farmers will get a revenue of 4.28 IDR. Thus, sweet corn farming at PIAT UGM is feasible to cultivate.

Abstract
Gasoline and diesel vehicles are one of the main sources of PMs generation which are harmful to human health and the environment. The light emitted from the headlights of these vehicles may cause to make the PMs more/less/not dangerous than the raw PMs to human health and the environment by changing their properties. However, there is no information available in this field. Therefore, this research is presented to investigate the effect of light emitted from one of the most common vehicle headlights (Halogen type) on the physical properties of PMs. Three PM samples taken directly from one diesel vehicle operating at an idle condition, and inside of a diesel particulate filter and gasoline vehicle exhaust pipe (engine was off) were exposed to the vehicle headlight for 6 hrs at 10 cm distance. It is observed that the vehicle light has the potential to change the structure, shape, and size of the PMs, while the fresh PMs from diesel vehicle receives more changes (43.5% increase in particle diameter) compared with the other two samples containing mature/aged PMs (increases of 3.6 and 9.9%, respectively). Also, the effect of the beam from the scanning electron microscope on the PM physical properties is presented.

Published: April 2022

Abstract
The diversity of Plants in the Andes is a complex stochastic network, this diversity is characterized by being distributed in three main families: Asteraceae, Poaceae and Rosaceae. The first two are the most diverse and have the Gynoxis and Chusquea genera respectively as the most dominant woody individuals in the last altitudinal floors above 3200 m. a. s. l. However, the Rosaceae family has less richness, it includes the genus Polylepis, present in the last tree line limit above 4300 m.a.s.l. This is the case of mono-specific forests of Polylepis rodolfo-vasquezii, a species highly threatened by anthropogenic impacts such as logging, burning, and llama-sheep farming. These forests are relict and generate a nurse effect, which allows the existence of important diversity such as Gynoxis nitida, Miconia latifolia, Bomarea dulcis and Displostephium rupestri and Brachyotum rostratum. However, the impacts generate complex plants diversity responses, where the nurse effect can become into a competition effect, especially with Gynoxis nítida, which can take advantage of the ecological niche to promote the increase in abundance of its young individuals against those of P. rodolfo-vasquezii, which is reduced by anthropic activities.

Published: April 2022

Abstract
While Circular Economy (CE) strategies have been discussed as solutions for negative environmental impacts, companies are facing various challenges in applying CE strategies and redefining their business models. Recent research articulates that to achieve the CE goals, businesses should collaborate with each other within an ecosystem in which values are equally captured among all the stakeholders by governing and managing data flows. In this ecosystem, all the actors and stakeholders can share data, information and solutions regarding to CE to help each other through the path and co-create CE values. Regardless of the transition towards CE, fashion and textile industry is still following the linear economy model (take, make, use, dispose), where only less than 1% of the recycled clothes get back to use cycle. For textile and fashion industry, data plays a key role in providing transparent flow of information on product’s lifecycle, from circular material resources and design all the way to the recycling and waste management. In this regard, a data-driven ecosystem in which various stakeholders can access the source of right data, can ensure the success of circularity of the entire supply chain. A data-driven strategy can help to engage and train all organizations to build a data-literacy ecosystem towards a common goal. The purpose of this paper is to identify the important role of a data-driven CE ecosystem in fashion industry within the case study of the circularity. ID® a solution developed by-circular fashion.

Published: April 2022

Abstract
The integration of non-enzymatic glucose sensing entities into device designs compatible with industrial production is crucial for the broad take-up of non-invasive glucose sensors. Copper and its oxides have proven to be promising candidates for electrochemical glucose sensing. They can be fabricated in situ enabling integration with standard copper metallisation schemes for example in printed circuit boards (PCBs). Here, copper oxide electrodes are prepared on flexible polyimide substrates through direct annealing of patterned electrode structures. Both annealing temperature and duration are tuned to optimise the sensor surface for optimum glucose detection. A combination of microscopy and spectroscopy techniques is used to follow changes to the surface morphology and chemistry under the varying annealing conditions. The observed physico-chemical electrode characteristics are directly compared with electrochemical testing of the sensing performance, including chronoamperommetry and interference experiments. A clear influence of both aspects on the sensing behaviour is observed and an anneal at 250 °C for 8 h is identified as the best compromise between sensor performance and low interference from competing analytes.
