Published: June 2024

Abstract
Sodium iron phosphate (NaFePO4) is widely used for cathode in sodium-ion batteries (SIB). SIB is a type of secondary battery that employs sodium ion as it charge carriers during battery’s operation. Here we report the synthesis of NaFePO4 using sodium chloride (NaCl) as a source of sodium via sol-gel method and study of its properties. X-Ray diffraction (XRD) data show the existence of maricite NaFePO4 and the secondary phase, Na3Fe2(PO4)3. Scanning Electron Microscope (SEM) result indicates the fairly homogeneous long-oval shaped of the maricite particle with the size range of ∼2 μm. Electrochemical properties studied by electrochemical impedance spectroscopy (EIS) measurement obtain the ion diffusion coefficient of NaFePO4 is 7×10−14 cm2s−1 that is in line with other types of SIB.

Abstract
Mangrove forests are an important natural resource in providing ecosystem and ecological services as a nature-based solution for coastal protection, including on Lepar Island. This research aims to analyze the composition of mangrove species and the mangrove health index on Lepar Island. The field data collection method uses a systematic sampling method. Analysis of mangrove community structure uses the Shannon-Weiner index, while analysis of mangrove density and canopy cover uses the hemispherical photography method. The research results show 11 species from 5 mangrove families are found on Lepar Island. The Importance Value Index at the four stations varied sequentially, namely Sonneratia alba (158.84%), Bruguiera gymnorrhiza (202.88%), Ceriops tagal (110.42%), and Rhizophora apiculata (300%). Density is generally in the sparse category, and canopy cover is in the good category. The mangrove health index at station 1 (51.83%) is in the medium category, while other stations show the MHI value of <33.33% or in the poor category. Mangroves have some benefits for humans and the surrounding ecosystem, such as preventing ecosystem degradation and climate change. Therefore, mangroves need to be preserved and monitored.

Abstract

Dendrobium stockelbuschii and Dendrobium sylvanum orchids are in great demand in Indonesia because of their uniqueness. Plant breeders keep trying to breed this orchid to maintain its uniqueness. Cytological information of D. stockelbuschii and D. sylvanum helps plant breeders in the breeding process. This research aims to determine the cytological characteristics such as chromosome number, size, shape, and karyotype. This study was conducted at the Plant Breeding Laboratory, Faculty of Agriculture, Sebelas Maret University. Data analysis was carried out descriptively based on chromosome observations. The results show that both orchid species have several chromosomes 2n = 38. The average chromosome length in D. stockelbuschii was 1.84 ± 0.52 μm to 2.05 ± 0.54 μm and in D. sylvanum was 2.32 ± 0.64 μm to 2.60 ± 0.68 μm. D. stockelbuschii and D. sylvanum had an average karyotype pattern of 2n = 2x = 38 = 18m + 1sm. The intrachromosomal asymmetry index (A1) value in both species tends to be metacentric, while the interchromosomal asymmetry index (A2) value in all species shows relatively tiny deviations in chromosome size.
Carbon Trading and Its Role in Shaping Indonesia’s Environmental Resilience to Climate Change
Authors: Ummul Firdaus Sunny , Nanda Sava Arkananta Fausta 
Published: June 2024

Abstract
In Indonesia, considerable environmental issues originate from industrial and agricultural activity, peatland fires, and deforestation. The government of Indonesia is legally required to adopt efforts to address these challenges. One feasible alternative under discussion is the formation of a carbon market, whereby firms are issued permits to release particular amounts of greenhouse gases. This notion has attracted support from both the European Union (EU) and numerous Asian nations. This paper investigates the function and importance of carbon emission trading systems in attaining carbon reduction targets. Leveraging global data envelope analysis (DEA), it formulates performance indicators for energy consumption and carbon emissions via a two-stage procedure. Furthermore, the study assesses the policy effect of carbon trading by developing counterfactual trajectories using the synthetic control technique. The study presents the notion of carbon markets and analyzes its potential to become a vital aspect of Indonesia’s climate mitigation plans. It indicates that carbon markets contain the ability to dramatically boost carbon and energy-carbon performance, mostly owing to technical restrictions and stakeholder participation.

Abstract
Genetic variability and the relationship between agronomic characters have an important role in the development of high-yielding soybean varieties. The aim of the research was to study the genetic diversity and the closeness of the relationship among the agronomic characters of soybean lines in tidal swamp land. The results showed that broad genetic variability was found in the number of branches and seed yield, while the other characters had narrow genetic variability. Individuals in the family are relatively evenly distributed. Based on the PCA biplot, the contribution of agronomic characters was in the similar direction as seed yield, except for maturity. However, there were no characters that are significantly correlated with seed yield. Significant phenotypic correlations were obtained among the number of filled pods, plant height, the number of branches, and the number of reproductive nodes. Almost all of the high agronomic characters belong to the Dh/Arg progenies. The highest seed yields were obtained by Dw/Arg-7 and Dw/Arg-12, namely 2.49 and 2.41 t/ha, respectively. The lines with high seed yield potential were also shown by the Gjs/Arg and Sh/Arg progenies. Dw/Arg-7 and Dw/Arg-12 can be assessed in plant breeding process to obtain high yielding soybean varieties adaptive to tidal swamp areas.

Abstract
Knowledge is a valuable asset in today’s digital age. Knowledge sharing is vital in building understanding, creating creative ideas, and developing innovations that greatly benefit. Agriculture is an essential sector of the world economy, including coffee. Coffee that is cultivated and processed according to quality standards will have high quality, good taste, and be more competitive both in national and international markets. On the other hand, the practice of robusta coffee production quality standards by farmers is still not as expected. Knowledge sharing by coffee farmers will expand the range of dissemination, knowledge, and enthusiasm in implementing quality standards. This study explores the benefits of knowledge sharing from a farmer’s perspective for implementing robust coffee production quality standards. This research method is qualitative (case study strategy) and NVivo12 Plus application for analysis. The research found that the benefits of knowledge sharing felt by farmers include benefits for personal lives, social lives, coffee standard operating procedure practices, and coffee farm development. This research will add new facts about knowledge sharing by farmers and increase understanding of the impact of knowledge sharing on implementing robusta coffee production quality standards.

Published: June 2024

Abstract
Media composition is the main factor in the success of plant tissue culture. This study aims to find alternative media formulas using AB-Mix and Gandasil-D for shoot propagation of pineapple. The study used a factorial completely randomized design (CRD). The first factor was the AB-Mix concentration consisting of: 2.5 ml/L, 5.0 ml/L, and 7.5 ml/L. The second factor was the concentration of Gandasil-D consisting of 1.0 g/l, 1.5 g/l, and 2.0 g/l. Each treatment medium added 2 ppm BAP and 0.5 ppm NAA as plant regulators. Parameters observed included the time of shoot emergence, the number of shoots, the number of roots, and leaves number. The results showed that the concentration of AB-Mix affected all observed parameters, while Gandasil-D and the interaction between Gandasil-D and AB-Mix had no significance. AB-Mix 7.5 ml/l was the best treatment because it resulted in shoot emergence time (30.55 days after induction), number of shoots (3.55 shoots/explant), number of roots (2.05 roots/explant), and number of leaves (14.66 leaves/explant) were not significantly from MS media. Based on the regression analysis carried out, it is still possible to increase the concentration of AB-Mix to increase the number of shoots produced.

Abstract
Rural development requires the internet and digital technologies for sustainable development. There is ample evidence that rural communities have less contact with the internet and digital technologies than urban communities. This digital divide will hinder development. Therefore, efforts to bridge the digital divide are essential for better development policies. On the other hand, studies on impacts and the factors that drive this gap have not been explored. This study aims to explain the digital gap’s impacts and its causal factors in rural development. This research is a narrative review of 16 articles from reliable sources such as scopus.com. The results of the literature review are summarized to answer research questions. The study found that the digital divide impacts rural socio-economy, rural socio-culture, rural socio-politics, and rural environments. This study’s drivers of the digital divide include demographics, human resource capabilities, geographical conditions, limited infrastructure, internet networks, uneven economic development, and policy failure. The impacts and drivers of the digital gap described in this study contribute to some of our efforts to bridge the digital divide while providing insights for future research.

Abstract
In Indonesia, elephant grass seeds used by farmers are in the form of cuttings or vegetative material. Currently, there is no standard for the cuttings used to produce high-productivity elephant grass. Therefore, research was conducted to determine the optimal size of cuttings for achieving good elephant grass productivity. The study was conducted in the field station area of Rancamaya, Bogor. A factorial group randomized design with 5 replications was employed for the research. The first factor was the type of elephant grass, consisting of 1) Pakchong and 2) Taiwan, while the second factor was the size of the cuttings, consisting of 1) 5 cm long cuttings, one node, 2) 10 cm long cuttings, one node, 3) 15 cm long cuttings, one node, and 4) control (two nodes as per usual farmer practice). The research results indicated that there was an interaction between the type of elephant grass and the size of cuttings for leaf length, fresh and dry leaf weight, dry stem weight, and total dry weight. The 5 cm cuttings of Pakchong had the highest fresh and dry leaf weights (P<0.05). The highest dry stem and total weight were obtained with the control size cuttings of Pakchong. The number of tillers was influenced by the size of cuttings, with the control size cuttings having the highest number of tillers, although not significantly different from the number of tillers for the 5 cm and 15 cm cuttings. The highest total fresh weight was obtained with the 5 cm cuttings and Pakchong. This study indicates that 5 cm cuttings can be used as cutting material to produce Pakchong and Taiwan with optimal forage production. Further research is needed to assess the forage quality.

Authors: Widono S , Dewi F C 
Published: June 2024

Abstract
Soybean (Glycine max L.) is one of the agricultural commodities needed in high quantities in Indonesia. Using agroforestry systems for soybean cultivation can solve the domestic fulfillment of soybean needs. The moist environmental conditions of agroforestry plantings due to shading make soybeans susceptible to leaf rust disease. The pathogen Phakopsora pachyrhizi causes leaves to fall off early, inhibiting soybean seed pod growth. Research on the incidence of leaf rust disease in several soybean varieties is essential to optimize soybean production in agroforestry systems. The study was conducted from June to October 2023 in the Special Purpose Forest Area (KHDTK) of Alas Bromo, Karanganyar, Central Java, Indonesia. The experiment used a randomized experimental design (RAK) with seven soybean varieties: Anjasmoro, Agromulyo, Dena-1, Dena-2, Denasa-1, Denasa-2, and Devon-1. Disease incidence observation was based on visual symptoms. The disease incidence was in the range of 3.33-26.67%. The highest incidence occurred in the Denasa-1 and Dena-2 varieties, while the lowest was in the Anjasmoro and Dena-1 variety.

Abstract
Startup companies have had a significant influence on the growth of the economy. Nevertheless, they are prone to failure. Resources, both tangible and intangible, are essential for the sustainable growth of start-up companies. The main objective of this study is to gain a thorough comprehension of the classification of agricultural startup companies in ASEAN countries, taking into account their available resources. This study employs data sourced from Crunchbase, a comprehensive database including information on 201 agricultural startup companies operating in ASEAN countries. The study primarily focuses on analyzing two main variables: tangible and intangible sources. The study employed the K-means clustering algorithm to analyze the attributes of agricultural startup companies. The study’s results indicate that startup companies in ASEAN countries can be categorized into three distinct clusters. The first cluster is made up of players who have a great deal of experience and who have the highest levels of income, funding, and personnel count. The second cluster is made up of players with a moderate amount of experience who have a low CB Rank, Funding, and Estimated Revenue, but they have a moderate number of employees. Inexperienced players make up the third cluster, which has a higher total quantity of investment and income but a very small number of employees. This group is characterized by greater total investment and income.

Abstract
Matoa (Pometia pinnata JR Forst & G Forst) has potential as a biodiesel raw material. Chitosan can increase plant growth by stimulating the biosynthesis of auxin and tryptophan. This research aimed to get the chitosan application time and the matoa type that can increase matoa growth. The method used was a completely randomized design (CRD) with two factors. The first was the application time of chitosan (without chitosan application, morning, afternoon, a combination of morning and evening) and the second was matoa type (red, green, and yellow). Chitosan was given at a concentration of 4%. Data analysis used analysis of variance and continued with Duncan’s Multiple Range Test (DMRT) at the 5% significance level. The results showed that chitosan application in the morning time gave the best results on the photosynthetic rate, the afternoon gave the best results on the height and photosynthetic rate, and the morning and afternoon gave the best results on the stem diameter. The interaction of chitosan application time in the afternoon with green matoa species gave the best results on the plant height and in the afternoon with red matoa and in the morning with green matoa gave the best results on the photosynthetic rate.

Published: June 2024

Abstract
Wild vegetable species are native or naturalized plants that thrive in their natural habitat. This study aims to look into indigenous knowledge about using plants as vegetables and how it affects food security and diversity in the Aceh Tamiang region. Plant material was randomly collected from three subdistricts in Aceh Tamiang, Indonesia. Ethnobotanical data was collected through investigations and semi-structured interviews. A total of 90 respondents, 30 from each sub-district, were selected randomly. Data was cross-checked and verified using the informant context approach and group discussions. The data were examined employing descriptive statistics and quantitative ethnobotanical approaches. We discovered 42 different species of wild vegetables. The majority of these plants are harvested from the wild by consumers in the area. These findings suggest that various plants are able to be consumed raw, which could be a valuable resource for the local community during times of food insecurity.
