This study was designed to evaluate effects of using different levels of cassava meal in a concentrate cassava peel diet on chemical composition, in vitro gas production (IVGP) and rumen fermentation. The treatments applied were: A=cassava peel (20%)+ cassava meal (70%)+cassava leaves (5%)+moringa leaves (5%); B=cassava peel (20%)+ cassava meal (60%)+cassava leaves (10%)+moringa leaves (10%); C=cassava peel (20%)+ cassava meal (50%)+cassava leaves (15%)+moringa leaves (15%) cassava meal; D=cassava peel (20%)+ cassava meal (40%)+cassava leaves (20%)+moringa leaves (20%); E=cassava peel (20%)+ cassava meal (30%)+cassava leaves (25%)+moringa leaves (25%) with 3 replications arranged in a Randomized Block Design (RBD). The result showed that the increasing levels of cassava meal in the ration significantly increased organic matter (OM) and nitrogen-free extract (NFE) content (P<0.05), but reduced crude protein (CP), ether extract (EE), crude fiber (CF), neutral detergent fiber (NDF), and acid detergent fiber (ADF) contents. Similarly, a significant increased (P<0.01) were found in values of cumulative in vitro gas production, dry matter and organic matter digestibility, but decreased NH3 concentration (P<0.05) due to the increased of cassava meal. It is concluded that increasing levels of cassava meal in concentrate has led to higher OM content of the ration and being available for rumen fermentation.

Published: November 2021

This study aims to evaluate local forage’s potential and nutritional content in the Payo agro-tourism area of Solok, West Sumatra, Indonesia, to be used as a ruminant feed. This study used a survey method by taking a sample of the forage that grows a lot in the area and then analyzed its nutritional content. The nutritional content analyzed were dry matter, ash, crude protein, crude fiber, crude fat, calcium, and phosphorus minerals. At the same time, the TDN value and the extracted material without nitrogen were calculated based on the formula. The results showed that 12 types of forage have the potential as ruminant feed, namely Panicum maximum, Tithonia diversifolia, Gliricidia sepium, Digitaria sp, Centrocema pubescens, Calliandra calothyrsus, Stachytarpheta jamaicensis, Bidens pilosa, Ipomea triloba, Micania Scandens, Asystasia gangetica, and corn straw. This study shows that Calliandra calothyrsus has the highest crude protein content, and Corn straw contains the lowest crude protein. The highest and lowest TDN values were Gliricidia sepium and Panicum maximum, respectively. Through the linear programming program, these 12 plants can be formulated into 4 ration formulations with 58% TDN and 15-16% crude protein.

Authors: Benu I , Malelak G E M , Jelantik I G N
Published: November 2021

An experiment with the objective to investigate the effect of different temperature regimes during heat treatment of Gliricidia sepium leaves was conducted following a completely randomized design with 4 treatments and 3 replications. Gliricidia leaves were exposed to three temperature regimes namely oven heating at 60oC (T60), 90oC (T90), and 120oC (T120) respectively and followed by sun-drying compared to sun drying as control (Con). The dry matter and protein degradation were measured using In Sacco method in three fistulated Bali cows fed a standard diet. Protein solubility (a) and the insoluble but potentially degradable fraction (b) were linearly reduced (P<0,001) by the increased temperature in the oven as compared to sun drying. The degradation rate (c) of protein in the rumen was increased at all heating treatments. The effective dry matter and protein degradation of gliricidia leaf was significantly (P<0,01) reduced by heat treatment in T90 and no further reduction in T120. The solubility fraction of DM was significantly reduced (P<0.05) when heated in the oven at 120oC, meanwhile the b value for DM linearly decline with the increasing heating temperature. Heating also increased the lag time required for the degradation to commence. It, therefore, can be concluded that oven drying at 90oC is a simple effective means to reduce ruminal protein degradation of gliricidia leaves.

Published: November 2021

The present experiment aimed to investigate the effect of introducing different pasture legumes on the growth profile and forage production of the selected native pasture grass species at different stages of growth. In a completely randomized design with 5 treatments and 5 replications, the mixture of Sorghum plumosum (SP) and Bothriochloa pertusa (BP) was introduced respectively with one of the forage legumes ie. Alysicarpus vaginalis (AV), Pueraria phasoloides (PP), Desmodium incanum (DI), and Clitoria ternatea (CT). Growth profile and forage production were measured at 40, 60, and 80 days after planting. Results showed that CT and PP significantly improved the growth and DM production of SP and suppressed (P<0.05) the growth of BP during the early vegetative stage but did not during the late vegetative stage. Introduction of legumes reduced (P<0.05) DM production of SP and the total forage production but improved (P<0.001) the DM production of B. pertusa as well as a leaf:stem ratio of both types of grass at the generative stage. PP had the highest (P<0.05) contribution of legumes to the total DM forage production during early and vegetative stages, meanwhile AV and DI during the generative stage. In conclusion, the introduction of forage legumes did not improve the DM production of both grass species but modify their growth profile toward a better quality as shown by increased leaf:stem ratio. P. phasoloides provide the highest foliage during the vegetative stage and A. vaginalis and D. incanum during the generative stage.

Published: November 2021

In the long term, fungi attacks will cause a decrease in the quality of corn during storage. In this case, Aspergillus flavus and Aspergillus parasiticus have become a serious concern related to food safety because of their ability to produce aflatoxins which are toxic to humans and animals. Nowadays, feed industries use fungicides to control fungal infections before the storage period due to their affordability, but the chemical residues are detrimental to our health. Therefore, an alternative method was needed to prevent and control fungi and aflatoxin formation in corn. One of the potential methods to apply is the gaseous ozonization. This research was conducted to investigate the potential of ozone in preventing fungal attacks and aflatoxin formation in corn, assuring that the corn quality can be maintained during the storage period. The objective of this study was to determine the effect of ozone on maintaining the quality of corn during storage, especially to reduce fungi colonies and aflatoxin formation. The experimental design used in this study was a completely randomized design with two treatment factors, namely temperature (20, 30, and 40°C) and exposure time (30 and 60 minutes). Corn quality parameters observed include moisture content, total fungal, moldy kernels, damaged kernels, and aflatoxin (AFB1, AFB2, AFG1, AFG2) contamination. The results showed that ozone treatment had an effect on reducing total fungal and aflatoxin contamination in corn, however, it had no effect on the moisture content, moldy kernels, and damaged kernels of corn. The optimum effect was obtained when the ozonization was conducted at a temperature of 20°C for 60 minutes exposure time, which results in the highest reduction in total fungal and total aflatoxin contamination of 36.77% and 92.45% respectively.

Published: November 2021

This study aims to examine the determinants of environmental performance on the firms listed in the agriculture sector of the Indonesian Stock Exchange. The analysis technique uses multiple regressions to observe 67 firms listed on the Indonesian Stock Exchange in the agriculture sector during 2016 – 2019. Furthermore, the independent variables consist of return on equity (ROE), firm age, size, leverage, and audit firm; and the dependent is environmental performance. The result shows that return on equity negatively affects environmental performance while firm age, size, and leverage have a positive effect. Furthermore, audit firm does not affect environmental performance in Indonesian Agricultural Firms. Therefore, firms with higher age, bigger sizes, and leverage will likely increase environmental performance even though profitability has decreased. Several factors such as firm age, size, leverage, and profitability should be considered to analyze environmental performance.

In Indonesia, there are three management systems of rice fields, namely organic, semi-organic and conventional. The research aimed to determine the fertility index of rice fields with different management systems on different soil types (vertisol, ultisol, inceptisol). Each combination of the management system and soil type is taken three soil samples as a repetition. The soil parameters analyzed were pH H2O, total-Nitrogen, available-P, available-K, exchangeable-Ca, exchangeable-Mg, soil organic carbon, Exchangeable-Al, cation exchange capacity, and base saturation. The soil fertility index was determined based on the Minimum Soil Fertility Index (MSFI). Data analysis used was Pearson’s Correlation Analysis and Principal Component Analysis (PCA) to determine MSFI. The MSFI values were derived from indicators that have high scores on correlation analysis and PCA. The results showed that the fertility index of rice fields from 3 types of soil ranged from 0.46 to 0.57. Vertisol rice fields have the highest soil fertility index ranging from 0.52-0.57. Conventional management of inceptisol soil has the lowest soil fertility index of 0.46. Vertisol rice fields with organic management with a soil fertility index of 0.57 are the most ideal rice field management system.

Published: November 2021

In the latest years, a disease epidemy of Moler caused by Fusarium
oxysporum f.sp. cepae have just occurred in Brebes Central Java. The disease intensity, however, varies between the shallot production lands. Some lands show suppressive with disease intensity lower than 5%, and others are conducive to disease intensity over 50%. It is interesting that in Brebes occur suppressive and conducive soil to moler disease. The suppressiveness may be determined by environmental conditions, including chemical soil characters. This paper reports the chemical character of suppressive and conducive soil to moler disease in Brebes. The evidence shows that the suppressive soil is more fertile than that conducive one. The suppressive soil is chemically characterized by significantly higher organic mineral, C-organic, P-available, K-exchangeable, and Cation Exchange Capacity than that conducive one.

Is agriculture an engine of economic reconstruction and development in the case of the Republic of Burundi?
Authors: Aboyitungiye J B , Prasetyani D
Published: November 2021

Despite its importance for the economy, the agricultural sector faces many constraints that hamper its growth. With the increase in the world population and the demand for food production, farmers need to produce more with less arable land. This study used the ARDL approach to model the long-term and short-term dynamics and proposed examining the agricultural sector’s contribution to Burundi’s economic growth. Econometric estimations revealed that the gross domestic product per capita, agricultural, and exports (value-added) have long-run relationships but at different levels. The study, therefore, revealed that inflation persists in the short and long term. The consumer price of agricultural products reduces the country’s economic growth. Major adjustments in agricultural, environmental, and macroeconomic policy at national levels will have to be made to create the conditions for sustainable agricultural development.

Published: November 2021

Apple cactus (Cereus sp.) is a genus of cactus, and two species that are often crossed are long spines (Cereus jamacaru) and short spines (Cereus peruvianus). Those species have seeds with physical dormancy, that is, seed mucilage that can inhibit the germination process. This research aims to study the effect of parental plants and washing materials on the germination of F2 apple cactus seeds. This study used two-factor RCBD using 3 parental plants of the F2 generation of apple cactus (C. jamacaru open pollination, C. peruvianus × C. jamacaru, C. jamacaru × C. peruvianus) and 5 washing materials (without washing, pH 8, distilled water (pH 7), pH 5, and pH 9) which was carried out in 3 repetitions. The results showed that seeds of the cross C. jamacaru as female parent (C. jamacaru open pollination and C. jamacaru × C. peruvianus) produced better germination than seeds from the cross of C. peruvianus as female parent (C. peruvianus × C. jamacaru). Although the washing material didn’t significantly affect the germination of F2 apple cactus seeds, there was an influence of using pH 9 to minimize seed mucilage so that the extraction process was easier.

A total of 56.7% of Indonesia’s population today is concentrated in urban areas. More than 80% of Indonesians belong to the middle and lower socioeconomic class and this segment is the biggest consumer of milk products for young children aged 1-3 years called growing-up milk (GUM). Understanding the brand and customer behaviour is significantly important. This study aimed to examine the behavior of GUM brand switching on middle to lower socioeconomic class consumers in urban communities. The research was conducted in Malang Municipality, East Java Province, using guided interviews with questionnaires. The research respondents were 102 consumers of GUM that were selected by proportional random method in all five sub-districts. The data were processed using Structural Equation Modeling-Partial Least Squares (SEM-PLS). The results showed that the prior experience in purchasing variables had a highly significantly negative effect and the consumer dissatisfaction had a significantly positive effect on the process of brand switching for consumers of GUM products. Empty product stock in the store is one of the real examples of bad prior experience as well as dissatisfaction of the consumers that trigger them to change the old brand to new brand. The GUM companies have to maintain product suppliability.

Published: November 2021

This article discusses how policy innovation was developed for supporting gender equality in the environment and forestry development. The study focuses on how the design thinking-based policy innovation process is carried out and how social infrastructure for policy innovation is built to seek the transformation of understanding from gender-neutral to gender nature. The data were collected through focus group discussions, documentation studies, and in-depth interviews. The data were qualitatively analyzed with inductive thematic analysis method with Needs and Aspirations for a Design and Innovation process (NADI) framework and social infrastructure theory. The results show that policy innovations in environmental and forestry development based on design thinking were carried out through gender-responsive policy innovations that regulate forests to be sustainably managed for the welfare of women, men, and people with disabilities. Moreover, there were also innovative activities called GLEADS (Gender Leader Summit) and TEACH (Training for Eco-gender Activating Champions Hub) embodying National-regional Eco-forestry Hubs, which cooperated to develop innovations to improve gender equality. Multi-actor aspirations and situations in the innovation intervention process lead to a reframing of the innovation policy design process. This impacted the reframing of social infrastructure and changes in intervention treatment according to the management level.

Published: November 2021

High rainfall intensity causing high erosion rates in Indonesia. Land cover conditions greatly determine water degradation in the hydrological cycle. The shape and type of plants canopy have significant effect on soil structure and water absorption. This study aimed to examine the role of plant canopy on the value of rainwater canopy escape as a supporter of hydrological cycle. Tree species were determined based on the level of dominance at study site using transect method. The dominant trees are Sea Sengon Tree (Paraserianthes
falcataria), Teak Tree (Tectona
grandis), Suren Tree (Toona
sinensis) and Durian Tree (Durio
zibethinus). The results showed that high rainfall intensity with a long rain period affected the amount of canopy escape. Durian Tree has highest canopy density with value of 0.301, and Sengon Laut is the lowest with value of 0.240. The value of passing the canopy of the Suren Tree is lower than the other tree species. The shape of canopy of Suren tree, which is round and oval, also affects the lower pass value of canopy compared to other tree species. The higher the value of canopy density can reduce the value of canopy escape to support the hydrological cycle.

Dendrobium is characterized by long pseudobulbs or canes with soft leaves over the entire length, or in some species short or swollen pseudobulbs with two leathery leaves. The inflorescence is composed from dozens of flowers of different sizes and colors. This study aimed to identify the quantitative morphological character of five species of Dendrobium spp. namely D. mirbelianum, D. lamellatum from Java, D. anosmum from South Kalimantan, D. bracteosum from Papua, and D. purpureum from North Sumatera. The resulted dendrogram based on the similarity matrix were divided into two clusters, among the five species the value of similarity coefficient is 1.50. The first cluster is only composed from D. mirbelianum, the second cluster is D. lamellatum, D. purpureum, D. bracteosum, and D. anosmum which have more distant relationship with the other three orchids. Moreover, D. lamellatum and D. purpureum have the closest similarity coefficient with 0.81 value, which have bigger chance to use as the parents for hybridization. There are many Dendrobiums spp. distribution which based on the relationship area. In addition to quantitative properties, it also needs to be expanded to qualitative, anatomy, cytology, and also molecular characteristic to have more comprehensive data.

Indonesia’s total area of forest and waters is around 130.68 million hectares, but it consistently decreases yearly. The illegal land clearing for agricultural activity is considered as the main cause of the forest reduction, as around 5.6 million hectares of land burned between 2015 and 201 and it costs of hundreds of trillions to the country. In order to lessen the negative impacts of land clearing, Indonesian government indeed has started to promote a green economy campaign, known as sustainable development with an environmental perspective. This study aims to examine the relationship between illegal land clearing and its effect on the Indonesian economy and its relationship with the green economy campaign initiated by the Indonesian government. We use the data from the Indonesian Ministry of Environment and Forestry, Central Bureau of Statistics, Greenpeace Indonesia, and World Bank to analyze this issue. We find that the governments’ poor regulation and monitoring have caused forest and land fires almost every year and it has huge economic and environmental costs that should be paid by the government. Therefore, a strong law enforcement is needed so that the green economy campaign in Indonesia can be executed properly.

Published: November 2021

After introducing the Green Revolution in Indonesia and the Sustainable Farming System in Thailand, environmental issues in the agricultural sector became an interesting topic. This article discusses the efforts of the Governments of Indonesia and Thailand in implementing Agri-environmental policies (AEPs). The implementation of AEPs has become a discourse that in the last few decades has played an increasingly vital role for the government to encourage the Environmental Performance Index (EPI) and the Sustainable Nitrogen Management Index (SNMI). Indonesia and Thailand are two developing countries in the Asia Pacific that have great attention in implementing AEPs. Therefore, this research has two main objectives: 1) Analyzing the determinants of successful implementation of AEPs in the two countries, and 2) Analyzing the role of AEPs in each country for improving the EPI and SNMI. The method used in this research is comparative descriptive with a qualitative approach. Meanwhile, the data collection technique was carried out by studying documentation from various sources related to AEPs. The results show that Indonesia’s AEPs, the Green Revolution, improve the SNMI indicators. Meanwhile, the determinant of the success of the AEPs, namely the Sustainable Farming System in Thailand, is in optimizing the EPI.
miRNA target prediction of avian Z-linked DMRT1 gene during sex determination in chicken (G. Gallus)
Authors: Prastowo S , Ratriyanto A
Published: November 2021

Sex determination in dimorphic animal, such as chicken (G. Gallus), is controlled by the expression of doublesex and mab-3 related transcription factor 1 (DMRT1) gene. This gene act as sex determination switch by critically needed for testis differentiation and as antagonist of ovarian development. miRNA, is belongs to short noncoding RNA which modulate gene expression in specific or board targeted genes. This study was aimed to predict miRNA(s) candidate targeted to DMRT1 expression in chicken. In silico method was employed to mining miRNA targeted to DMRT1 using three online databases namely miRDB, TargetScan, and microT-CDS. Following prediction, clustering was performed to select common miRNA(s) in minimal two databases for gene ontology (GO) analysis. Totally 78 miRNAs were targeted to DMRT1 3’UTR, and eight miRNA(s) were found in minimal two databases. The GO analysis found seven distinct biological functions in membrane, cytoplasm, protein binding, nucleus, integral component of membrane and molecular function, and all are related to the cell growth namely cell proliferation. According to the result, it shows the possibility to use selected candidate of miRNA(s) targeted to DMRT1 to reveal the sex determination mechanism at early stage of chicken development.
The Network of Online Stolen Data Markets: How Vendor Flows Connect Digital Marketplaces

Published: November 2021

In the face of market uncertainty, illicit actors on the darkweb mitigate risk by displacing their operations across digital marketplaces. In this study, we reconstruct market networks created by vendor displacement to examine how digital marketplaces are connected on the darkweb and identify the properties that drive vendor flows before and after a law enforcement disruption. Findings show that vendors’ movement across digital marketplaces creates a highly connected ecosystem; nearly all markets are directly or indirectly connected. These network characteristics remain stable following a law enforcement operation; prior vendor flows predict vendor movement before and after the interdiction. The findings inform work on collective patterns in offender decision-making and extend discussions of displacement into digital spaces.
Brain adaptation to acute stress: effect of time, social buffering, and nicotinic cholinergic system
Authors: Nosjean Anne , Granon Sylvie
Published: November 2021

Both social behavior and stress responses rely on the activity of the prefrontal cortex (PFC) and basolateral nucleus of the amygdala (BLA) and on cholinergic transmission. We previously showed in adult C57BL/6J (B6) mice that social interaction has a buffering effect on stress-related prefrontal activity, depending on the β2−/− cholinergic nicotinic receptors (nAChRs, β2−/− mice). The latency for this buffer to emerge being short, we question here whether the associated brain plasticity, as reflected by regional c-fos protein quantification and PFC–BLA functional connectivity, is modulated by time. Overall, we show that time normalized the stress-induced PFC hyperactivation in B6 mice and PFC hypo-activation in β2−/− mice, with no effect on BLA. It also triggered a multitude of functional links between PFC subareas, and between PFC and BLA in B6 mice but not β2−/− mice, showing a central role of nAChRs in this plasticity. Coupled with social interaction and time, stress led to novel and drastic diminution of functional connectivity within the PFC in both genotypes. Thus, time, emotional state, and social behavior induced dissociated effects on PFC and BLA activity and important cortico-cortical reorganizations. Both activity and plasticity were under the control of the β2-nAChRs.

Background

Patients treated with anti-CD20 therapy are particularly at risk of developing severe coronavirus disease 2019 (COVID-19); however, little is known regarding COVID-19 vaccine effectiveness in this population.

Methods

This prospective observational cohort study assesses humoral and T-cell responses after vaccination with 2 doses of mRNA-based COVID-19 vaccines in patients treated with rituximab for rheumatic diseases or ocrelizumab for multiple sclerosis (n = 37), compared to immunocompetent individuals (n = 22).

Results

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific antibodies were detectable in only 69.4% of patients and at levels that were significantly lower compared to controls who all seroconverted. In contrast to antibodies, Spike (S)-specific CD4 T cells were equally detected in immunocompetent and anti-CD20 treated patients (85–90%) and mostly of a Th1 phenotype. Response rates of S-specific CD8 T cells were higher in ocrelizumab (96.2%) and rituximab-treated patients (81.8%) as compared to controls (66.7%). S-specific CD4 and CD8 T cells were polyfunctional but expressed more effector molecules in patients than in controls. During follow-up, 3 MS patients without SARS-CoV-2-specific antibody response had a mild breakthrough infection. One of them had no detectable S-specific T cells after vaccination.

Conclusions

Our study suggests that patients on anti-CD20 treatment are able to mount potent T-cell responses to mRNA COVID-19 vaccines, despite impaired humoral responses. This could play an important role in the reduction of complications of severe COVID-19.
