Smart Soil Sensor Kit, a Rapid test for Determining Soil Properties(Summary)

Indonesia as an agricultural country has varies of soil types and soil fertility levels. In orderto improve plant productivity, it should be followed by improving and maintaining soil fertility
that can be achieved by supplying adequate nutrient to obtain optimal yields. The additionof proper plant nutrients improves soil fertility, and it is also a key element to increase plant
productivity, The accurate information on soil properties is one of the factors for determining
the proper amount of nutrient added into soil. Based on that, Indonesian Center for
Agricultural Land Resources Research and Development (ICALRRD) under Ministry ofAgriculture has developed an innovation a 4.0 technology for determining soil chemical andphysical properties and equipped with fertilizer recommendation for rice, maize and soybean
called as Smart Soil Sensing Kit.
This Smart Soil Sensing Kit is developed based on NIR spectrometer (NeoSpectra) for thepredictions of soil properties. Meanwhile for the fertilizer recommendation, it developed
based on field trial data based. This work started from 2018 and Smart Soil Sensing Kit 1,0
version has been launched on December 5, 2019 on the World Soil Day Celebration. In 2021,
we have developed The Smart Soil Sensing Kit 1.1 version, which already using android
based connected to smartphone. The research teams are still doing the updating andimproving the features and recommendation for plantation and horticulture crops. It is
expected that by developing Smart Soil Sensing Kit, precision fertilization, with a site-specificcondition could be an effective option to improve plants productivity and maintaining soil
fertility conditions to support sustainable agriculture.

Mineral Concentrations and Nutritive Value of Tropical Legumes in West
Sumatra, Indonesia(Summary)
Animal keeping in the west Sumatra is a major and the most important source of income forthe majority of the population. Natural pasture especially tropical legumes and crop residues
contribute about 75% of the nutrient requirements for ruminants.

Legumes have great

potential to increase the productivity of livestock in the humid tropics. This study was carriedout to evaluate the macro and micro mineral concentrations and potential nutritive value oftropical legume forages (leaves and twigs) in West Sumatra during rainy and dry seasons.
The macro (Ca, P, Mg and S) and micro (Zn, Fe, Mn and Cu) mineral concentrations and thechemical composition, in vitro dry matter (IVDMD), organic matter (IVOMD) and crude protein
digestibility (IVCPD), in vitro gas characteristics and estimated metabolizable energy (ME)showed variation among legume forages and between different seasons. From the above
results, it could be concluded that macro and micro mineral concentrations and nutritive valueof the legumes grown in West Sumatra, Indonesia was relatively higher during rainy season
compared with dry season. Between the species, Pueraria phaseloides and Leuchaena
leucocephalaappeared to have better quality than other species. The chemical compositionof Pueraria phaseloides and Leuchaena leucocephalacontained much higher crude protein

but was generally lower in cell wall constituents (CWC or NDF) in both dry and rainy seasons.
It suggested that proper supplementation with sources of nitrogen and energy might berequired to support grazing ruminants, especially during dry season.
Further studies on feeding trials are needed to quantify the animal responses when offeredthese legume forages.

Best management practices and its effect on soil properties insmallholder oil palm plantations, Jambi Province, Indonesia(Summary)
The Best Management Practices (BMP) could improve oil palm production in smallholder
plantations. This study aims to identify the effect of BMP and farmers' practice (REF) on bulk
density (BD), total N, available P, and organic C. The research was conducted in thesmallholder oil palm plantations in Jambi Province, Indonesia. BMP applied pruned fronds
stacks in inter-rows and within rows with fertilizer application above it except nitrogen
fertilizer applied in the weeded circle. Besides, REF practice applied prune fronds stacks ininter-rows with all type of fertilizer application in the weeded circle. The result based ontransect analysis showed that organic C, total N, and available P significantly higher near oilpalm trees. In contrast, BD did not show a significantly different. Comparing BMP and REF
practice revealed that BD, organic C, and total N did not differ significantly in all point
observations. However, available P showed significantly different in point 2, 4, and 6. As thisstudy was conducted in the second year of BMP treatment, the soil properties of BD, organicC, and total N were not influenced by BMP treatment. Need longer term observation to identify
BMPʼs treatment which will be conducted in the fourth year of study. BMP study give land
management information to improve soil properties that support oil palm production.

Validation of laboratory analytical method(Summary)
Indonesian Soil Research Institute has 4 testing laboratories, namely Chemistry, Biology, Physics,
and Mineralogy. Laboratory of ISRI as national reference laboratory needs to update analyticalmethods and laboratory equipment used. To improve the quality of laboratory performance,
several methods or activities are carried out, including taking proficiency tests at national,
regional and international levels. ISRI Laboratory as the government representative for Sealnet,
Glosolan, and INFA. Besides that ISRI has a program every year to develop or adopt analyticalmethods by validating them such as CEC and humic acid. Currently the type of CEC determinationby using a manual percolation tool, while the limited personnel and the demand for quick andprecise analysis requires an increase in the ability of laboratory equipment that can simplify
analysis. CEC analysis method with an automatic percolation tool is a technology that can facilitate
analysis in the laboratory.

Meanwhile, humic acid is widely found in peat soils, where peat lands

in Indonesia are quite extensive, such as in Kalimantan and Sumatra. Validation of method
including limit of detection (LOD), limit of quantitation (LOQ), linearity, accuracy, precision anduncertainty.

Isolation and identification of hyphal bacteria from ectomycorrhizal fungal
isolates, and its role for fungal host growth.

(Summary)
Bacteria are cosmopolitan microbes. They can live anywhere as long as their environment
is supportive of the organism's life. They can also live even in other organisms as endo-symbionts.
Some endo-hyphal bacteria can affect a fungal habit or phenotype as an interaction outcome. Asan endo-symbiont-bacteria, the existence of bacteria in hyphal isolates is quite important to know.
This study detected and identified the bacterial diversity around some ectomycorrhizal fungal
isolates. 22 codes of ectomycorrhizal fungal isolates were used and gotten from Fungus/
Mushroom Resource and Research Center (FMRC), Tottori University. The hyphae had three
categories, such as Hyphae 1, Hyphae 2, and Hyphae 3. All hyphae (all categories) were observed
the colony growth on MMN Agar 1/5 (modified medium by 1/5 composition as the normalcomposition). Some results showed the better growth for hyphae 1, while some showed the best
growth for hyphae 3. The bacteria affect the fungal diameter colony and appearance on MMNA
(1/5) medium. The bacteria were 19 codes isolated from Hyphae 1. Then, the bacteria from
Hyphae 2 were 12 strains. All bacteria are described the colony appearance and SEM observation.
Some of them showed unique characters like yellow color and unusual shape cells. Qualitative
observation of bacterial existence on hyphae using SYTO BacLight Bacterial Viability Kits L13152.
Identification is conducting by Polymerase Chain Reaction (PCR) techniques using 10F and 1507R
of general bacterial primers. All bacterial isolates will be identified using molecular study. The
phylogenetic tree will be constructed using Randomized Axelerated Maximum Likelihood (RAxML)
software. Then, the bacterium will be continued to bacterial role tests of the fungal host growth.
The output of this study has a willing to explore bacterial diversity as hyphal bacteria andfind the new record for hyphal bacterial diversity. Then, studying about their role for their fungal
host growth. In Indonesia, not many researchers are interested in this research field. After
finishing the study in Tottori University, I am willing to search for a position as a post-doctoral
project in Japan. I would like to be a taxonomist for the microbiology field, especially for fungal
objects.

Title of Research

The Effect of Land Use Changes on Water Ecosystem in Relation to The
Distribution of Endangered Arowana Fish (Schleropages formosus) in
Sumatra Island, Indonesia.

(Summary)
Schleropages formosus (Arowana) is one of the surviving primitive fish species naturally
found in primitive habitats not affected by human disturbances. The fish is very famous aroundthe world among hobbyists because of its exotic appearance and scarcity. The protection of Asian
Arowana and its habitat is a major concern for several levels of stakeholders. One of the locations
for efforts toward the sustainable protection of Arowana in its natural habitat is in East-Central
Sumatra. This research identified the effect of land use change on the water quality in relation to
the distribution of Endangered Arowana. The purpose is to provide recommendations forsustainable plantation systems and Arowana conservation. We designated four wide areas
according to the stratification of river flows that pass through the Arowana conservation area andpresent land use. The QGIS 3.26 software was used to generate maps using the RUSLE method.
Arowana and water observation was carried out 4 times a year and replicated 5 times at eachobservation. We analyzed the extent of changes in the Arowana habitat to oil palm plantations
over a period of 2 years (2020-2021). There has been an increase in the area of oil palm
plantations by 517.67 ha (2,310.84 ha to 2,828.51 ha), all of these changes were in areas thatwere previously swamp and swamp forest. Some areas that previously had Heavy erosion
became very heavy, and also from moderate to heavy erosion. Since 2020 Arowana was foundin 89 individuals. Currently, the quality of water is still good for Arowana living, but the Arowana
is only found in the wide area of Middle Mahato. We continue to do observations until the
beginning of 2023 for the completeness of data for 3 years (2020,2021,2022). This research isone of the studies of the effects of agriculture (oil palm) on aquatic biodiversity, especiallyendangered species. In Indonesia, there is still much that needs to be analyzed regarding theeffect of agricultural activities on biodiversity. My job in Indonesia is as a lecturer at the Pasir
Pengaraian University. In the future, I intend to continue to do collaborative research with
Shimane University and Tottori University. This is for agricultural and biodiversity sustainability inIndonesia.

Rural Household Food Consumption in Bengkulu, Indonesia: Estimating a
Demand System Based on SUSENAS Microdata

Title of Research(Summary)< Current research >Food consumption is often used as an indicator to determine the welfare of consumers andhouseholds. Modelling consumer demand has been one of the most significant trends in consumer
theory literature over the last couple of decades. In this research, demand and consumption areused interchangeably. The research aims to estimate the food demand of rural households in
Bengkulu Province, Indonesia, using the Quadratic Almost Ideal Demand System (QUAIDS) andmicrodata from the SUSENAS. This study intends to estimate not only expenditure elasticities,
uncompensated and compensated price elasticities, and Morishima elasticities of substitution but
also the effects of household demographic characteristics on household food demand. We use
household expenditure data from the Indonesia Socio-Economic Survey (SUSENAS), a crosssection data survey collected annually by Indonesia Central Statistics Agency (BPS). There are
13 food categories that Bengkulu rural households consume. To simplify the estimation ofdemand, we aggregate these categories into five food groups, namely: staple food (rice, tubers),
animal food (fish, meat, egg and milk), vegetables & fruits (vegetables, nuts, fruits), preparedfood, and other food (seasonings, drinks, instant foods, oil and coconuts). The results show thatdemand for animal food is the most sensitive to food expenditure, whereas the demand for staple
food is the most expenditure inelastic. Staple food, animal food, vegetables & fruits, and otherfood are substitutes for each other. On the other hand, prepared food and staple food complement
each other. Other food is the easiest to be substituted, and staple food is the most difficult to be
substituted. The demographic variables, as well as prices and expenditures, impact household
demand. For example, as family size increases, the demand for staple food increases, while thedemand for animal food, vegetables & fruits decreases. Staple farmer households have a higher
need for staple food than non-agricultural households.

Due to being unmarried, divorced or

bereaved, single households have a lower demand for staple food but a higher demand for
prepared food.
< Future prospects >The finding from my current research will be an input to develop the demand food model in therural area with an additional variable, such as the effect of COVID-19.

Furthermore, I willcompare household food consumption between rural and urban areas before and after the
breakout of COVID-19.

I may discover many interesting new phenomena that can strengthen

existing demand theories.

As a lecturer at the University of Bengkulu, I intend to continue

collaborating with Tottori University.

This research is essential because it will provide an

overview of food consumption behavior in households in Bengkulu.

Household food consumption

behavior can be used to project food demand and imply for the policy of food security.
