Published: December 2019

AbstractAcidic mineral soil generally has mild acidic to high acidic reaction or pH ⩽ 5.5, with very low exchangeable bases that can exchanged and rich in oxide as well as Al and Fe hydroxides. Acidized soil can lead to increased toxicity from aluminum, iron, and manganese element to the plants and deficiency of phosphorous, alkaline cation (calcium, potassium, and magnesium), and molybdenum element as well as soil microbial population. This study aimed to observe the fractionation distribution of metal aluminum (Al), iron (Fe), and manganese (Mn) and soil microbial population in acidic soil horizon. Al fraction parameters included exchangeable Al (Al-exc), non-crystalline Al (Al-o), inorganic non-crystalline Al (Al-po), Organically Bound Al (Al-p), Low- and Medium- Stability Complexes with Organic Matter (Al-Cu) and High-Stability Complexes with Organic Matter (Al-pCu), exchangeable fractionation of Fe and Mn (Fe/Mn-exc), Fe and Mn from Bound to Carbonates/Acid- extractable, Bound to Fe-Mn Oxides/Reducible, Bound to Organic Matter Fe Mn/Oxidizible, Fe- Mn Residual and soil microbial population (total microbes andAcidithiobacillusbacteria). The results, distribution of Al fraction on the upper horizon of Jasinga and Lebak were dominated by stabilized organic amorphous Al fraction with fluctuative decrease of organic matter (Al-pCu), while the lower horizon tended to be inorganic amorphous Al (Al-op). The fractionation distribution of Fe fractionation on Jasinga and Lebak was dominated by Oxidizible Fe fraction. Mn fraction distribution on Jasinga and Lebak were dominated by Mn-residual fraction in each acidic soil horizon. The total population of Microbes andAcidithiobacillus.sp in each soil horizon decreased along with the alteration of soil chemical properties in each soil depth horizon.

Abstract
The aim of this study was to analyse the effect of a foodborne disease outbreak (Listeria Monocytogens) and factors which affect the consumption patterns of processed cold meat products by students at North-West University, Mmabatho Campus, South Africa. A well-structured questionnaire was used as a data collection instrument, 375 registered students who enrolled for postgraduate and undergraduate studies were randomly selected within two clusters. The sample size was calculated from the total population of 12864 students using RASOFT calculator. Data was captured and analysed using Microsoft Excel and Statistical Package for Social Science (SPSS) version 25 computer software. Probit Regression Model was employed to identify factors influencing consumption patterns of students after the Listeria Monocytogens outbreak. Factors such as gender, residence, allowance (Income), meal preference, regulation of meals time, price of alternatives and academic level were found to be statistically significant and they do influence consumption patterns of processed cold meat by both undergraduate and postgraduate students in North-West University Mmabatho Campus. The study concluded that disease outbreaks (Listeria Monocytogens) do have a negative impact on student’s consumption patens and switching behaviour. Findings further revealed that disease outbreak led to the majority of students spending more time preparing meals and this may have a negative effect on their academic and/or extramural activities.

Published: December 2019

Abstract
More than 1200 native Indonesian fish species inhabiting Indonesian inland waters have been used as human daily fish consumption. It brings to decline their population and even its species by year. Efforts of spawning some native fish species have been conducted, but the successful spawning limited during the rainy season. This paper, therefore, reviews the results of research related to using appropriate formulated diets for gonadal maturation and spawning some economically important native fishes. The tested fishes used were hoven’s carp (Leptobarbus hoevenii), knife-fish (Chitala lopis), Asian red-tail catfish (Hemibagrus nemurus), kissing gourami (Helostoma temmincki), snake-head (Channa striata), and hard- lipped barb (Osteochilus hasselti), This study showed that in general, formulated diet containing about 35% protein fed on these species resulted in gonad maturation whole year and successfully spawned under controlled hatchery. The larvae survived at a high rate after feeding a natural diet up to 30 day-age. Mass production of the juvenile could support the development of its culture and be used as restocking in inland open-waters as well.

Published: December 2019

Abstract
The low efficiency of nitrogen and potassium fertilization is one of the pressing problems in tropical agriculture. This is because the humid tropical climate, like what Indonesia has, which is characterized by high rainfall, causes a high rate of leaching of nitrogen and potassium in the soil. To improve fertilization efficiency, one practical option is to find a method of slowing down the release of available nutrients in the soil. Thus, the purpose of this study was to evaluate the pattern and rate of the release of nitrogen (in the form of ammonium and nitrate) and potassium from slow- release fertilizer (SRF). This study used three types of fertilizers, namely: SRF (13-8-10), SRF (19-12-15) and Mutiara granule fertilizer (16-16-16). Treatment dosages used corresponded to 600 kg/ha and 1200 kg/ha, with three replications, and observed over a 10-week incubation period. The results showed that ammonium release from SRF fertilizer in the first week that ranged 28.94% - 41.45%, then decreased progressively with incubation time, while that of nitrate ranged 5.77 - 7.21%, but increased over time. On the other hand, the potassium from SRF fertilizer was released by rates of 9.56% -24.58% during the first week, increasing with incubation time. The same pattern of nutrient release was observed in the case of Mutiara fertilizer, however at much greater rates compared to SRF, viz.: for ammonium (44.56 - 46.91%, at decreasing rate afterwards with incubation time), nitrate (26.33 - 30.10%, at increasing rates afterwards), as well as for potassium (15.39 - 15.75%, at increasing rates afterwards). In summary, the SRF (13-8-10), applied at a dosage corresponding to 1200 kg/ha yielded the slowest rate of nutrient release in the soil.

Utilization and Improvement of Marginal Soils for Agricultural Development in Indonesia
Authors: Suwardi  
Published: December 2019

Abstract
Indonesia is a humid tropical country that has very intensive weathering of soils resulting acidic soils such as Oxisols and Ultisols. In swampy ecosystems, organic matters accumulated become peat soils or Histosols. Reclamation of shallow peat for agricultural land will induce the forming of acid sulfate soils (Sulfaquept and Sulfaquent). Due to low fertility soils, the three of above soils are classified as marginal soils and now they are used for agricultural activities and some of them are still in forests. The use of marginal soils should refer to land suitability whether it is retained as a forest or used as agricultural land. The development of agricultural commodities on marginal soils must consider soil characteristics and agro-climate conditions. Oxisols and Ultisols have characteristics of low pH, low organic C, low macro and micro nutrients. In areas where rainfall is higher than 2,000 mm/year and evenly distributed throughout the year, oil palm plantations can be well developed. Meanwhile in the rainfall between 1,750-2,000 mm/year, rubber, cacao, coffee plants can be cultivated. Agricultural development in acidic soils need to be followed by the addition of soil amendments such as organic materials, humic substances, lime, fly ash, steel slag as well as fertilizers. Acid sulfate soils have a pH value of around 3 due to pyrite oxidation and usually low macro and micro nutrient content. Acacia mangium plants as raw material for pulp and oil palm plantation can grow quite well if followed by application of fertilizers and appropriate soil amendments. Peat soils are very fragile ecosystem so that in the upstream area and peat dome, they must be retained as forests. Peat can be developed for Acacia crassicarpa, oil palm, and rubber plants with good water and fertilizer management. Thin peat underneath mineral soil from river sediments can be developed rice field.

Abstract
The Ministry of Agriculture has optimism that soybean self-sufficiency can be realized in 2018. Consistency to stay on track that has been targeted has made Soybean Seed Management Unit (UPBS) activities accelerate with the technology of seed multiplication to supply quality seeds. This study examined the dissemination of technology and the existence of local knowledge, especially on consumption farmers to breeders as the output of UPBS activities. The method used is a descriptive qualitative method through literature studies and studies in the social field to explore the potential, roles, constraints and opportunities faced by farmers and soybean seed breeders related to local knowledge. The data collected consists of secondary and primary data. Benefit and Cost Ratio (B/C Ratio) analysis to determine the feasibility of changing consumption farmers to breeder farmers. The results show that farmers’ local knowledge changes with technology dissemination. Changes occurred in the use of quality seeds of New Superior Varieties (VUB) with the application of soybean integrated crop management (PTT) models that were able to increase yields 16-27%. Local knowledge maintained in terms of attack control and infestation of plant pests (OPT) in the concept of Integrated Pest Management (IPM). In this case, local knowledge of breeder farmers can compensate for location-specific technology. At the field level, a combination of technology and local knowledge was followed by an increase in income from consumer farmers to B/C soybean growers. The ratio of consumption farmers to 1.45 increased to 1.69 for breeder farmers.

Published: December 2019

Abstract
Betaine is proven as a digestibility enhancer that improves egg production. This study investigated the egg production trajectory of quails receiving betaine supplementation. The experimental population comprised of 204 quails (Coturnix coturnix japonica) which were allotted to two treatments and six replicates with 17 quails each. The quails were given a basal diet containing 2,700 kcal/kg of metabolizable energy and 18% crude protein, without (Control) and with 0.12% betaine supplementation (Betaine). Egg production were collected from adaptation (age 42-62) and treatment period (age 63-118), and they were subjected to T-test. The data were plotted to obtain the egg production trajectory. A logistic regression model was employed to see the trend of the egg production patterns. There was no significant difference in egg production during adaptation period. Furthermore, during treatment period, the egg production enhanced (p<0.01) following betaine supplementation (59.54±13.11% vs 63.72±13.52%). This finding was confirmed by egg production trajectory curves. Results from logistic regression showed that the trend for both treatment groups were similar with slightly different fitness. Coefficient determination (R2) for both groups were 0.96 and 0.95, respectively. Betaine supplementation was able to improve quail egg production; however, the trend of trajectory was similar from that without supplementation.

Abstract
This experiment was conducted in order to evaluate the effect of undegradable dietary protein (UDP) level on milk production and composition of 24 lactating dairy cows. Treatments consisted of T0: ) control diet without UDP (forage and concentrate were offered in total mixed ration); T1: control diet without UDP (forage and concentrate were offered separately); T2: control diet + UDP 40 gr/L milk + mineral mix; and T3: control diet + UDP 60 gr/L milk + mineral mix. Data were analyzed using analysis of variance (ANOVA) and the differences between treatment means were examined by duncan multiple range test (DMRT). The results showed that UDP supplementation significantly (p<0.05) affected nutrient consumption (dry matter, organic matter, crude protein and total digestible nutrient). In addtion, UDP supplementation significantly increased milk production and 4% FCM production (p<0.05). A higher level of milk production and 4% FCM yielad in animals fed with T2 and T3. Thus, UDP supplementation may be an alternative supplement for the lactating dairy cows.

Published: December 2019

Abstract
Luteinization is process of turning granulosa into luteal cells to produce progesterone. It’s indicated by lipid accumulation which controlled by AMPK gene, the expression is controlled by miRNAs at pre and/or post transcriptional level. Previously, 4 miRNAs namely miR-19b, miR-130, miR-101, and miR-19a were predicted targeted to AMPK. For that, this study aimed to identify board target of these miRNAs to genes in specific metabolic pathway. An insilico study was performed using online molecular databases that are miRDB (www.mirdb.org) and DAVID Bioinformatic Resource (https://david.ncifcrf.gov/) and Genomes (KEGG) pathway (https://www.genome.jp/kegg/pathway.html). Result shows that miR-19b, miR-130, miR-101, and miR-19a targeted to 1121, 738, 859, and 1117 respectively. A total 3835 genes were analyzed, resulted five annotated functional group namely coiled coil, serine/threonine-protein kinase, ATP-binding, nucleotide-binding, and kinase. According to gene ontology analysis, genes were grouped at nucleoplasm, cytoplasm, nucleus, golgi apparatus, and transcription factor complex process. Moreover, pathway analysis found five top KEGG pathways that are FoXO, MAPK, cAMP, Sphingolipid, and prolactin signaling. Two genes namely RAF1 and AKT3 were involved in all pathways. It is concluded the expression of miRNA group targeted to AMPK affect to complex cellular metabolism pathway direct and/or indirectly.
