Identification of Functional Microbes and Soil Stable Carbon in the Rhizosphere of Horticultural Plants in Land Affected by Cold Lava of Mount Marapi, West Sumatra
The Marapi area is mostly cultivated by the community as horticultural agricultural land, horticultural plants will be very vulnerable to being able to survive in these conditions. Research related to the identification of functional microbes that in this case greatly affect the availability of plant nutrients and carbon stability in the provision of nutrients in the root environment of horticultural plants will be a concern in the short term. The purpose of this study was to identify functional microbes that still survive in extreme conditions of cold lava floods and the stability of soil carbon in the rhizosphere of horticultural plants in the area affected by the Marapi cold lava flood in West Sumatra. Changes in the physicochemical and biological properties of soil in the rhizosphere of horticultural plants that have been identified through several physical, chemical and biological parameters of the soil. The lower slopes affected by the cold lava flood of Mount Marapi are the land with the worst damage conditions. The soil volume weight increases and the total pore space of the soil decreases with the impact of the land by the cold lava flood of Mount Marapi. The water content, organic C and stable C of the soil decrease with decreasing slope position. The population of microorganisms; the population of bacteria, fungi and phosphate-solubilizing bacteria also decreases with decreasing slope position. It is recommended to revitalize the lands for horticultural plants due to the damage of the cold lava flood of Marapi.

Impact of pineapple core storage duration on the properties of the developed bromelain
This study examines the impact of pineapple core storage duration on the properties of the bromelain enzyme produced. Bromelain is a protease enzyme used in many applications in the agro-food, pharmaceutical and cosmetic industries. This study aimed to determine changes in bromelain enzyme activity during storage of pineapple core at various durations (0, 12, 24, and 48 hours). Bromelain was extracted by mixing pineapple core juice with 90% ethanol, followed by a separation process with filtration. The results showed that bromelain enzyme activity peaked at 12 hours of storage and then loss significantly after 24 to 48 hours. This loss was caused by changes in pH, increased water content, and protein degradation that affect enzyme stability. This study highlights the importance of optimizing storage duration to maintain bromelain enzyme activity and supporting sustainable pineapple waste management by using pineapple core as a source of high-value enzymes.

This development significantly impacts the local community, particularly those residing in the buffer zone of the new capital. This study aims to assess the Human Development Index (HDI) and the welfare of coastal and non-coastal communities within the IKN buffer zone. Using census sampling, the study involved 5,353 families from eight villages in the buffer zone, comprised of coastal and non-coastal areas. Findings revealed that the HDI was generally low across the study areas, with only two regions displaying modest HDI scores, indicating that the population remains underprivileged. This research contributes to the social humanities field by providing insights into the welfare of communities affected by the establishment of the new capital. This area has been relatively underexplored in existing literature.
Socio-economic transformation for sustainable agromaritime
Optimization of Application of Various Types and Doses of Foliar Liquid Fertilizers on Growth and Yield of Pak Choy (Brassica rapa)
Pak choy is a highly favored vegetable with a high market value. The continuous urban land conversion requires agricultural innovations such as hydroponic cultivation. Nutrients play a crucial role in determining the success of hydroponic cultivation, which in turn affects plant growth and yield. Although AB mix is commonly used in hydroponics, its high cost necessitates the exploration of alternative liquid foliar fertilizers. This study was conducted at Arif Hydrofarm, Padang City, to determine the interaction between the types and doses of liquid organic fertilizers on the growth of pak choi plants. A split-plot design was employed, with the main plot consisting of different liquid organic fertilizers (Ferti Grow, Good Grow, and NPK Vertine) and subplots consisting of fertilizer doses (20 ml/L and 25 ml/L). Data were analyzed statistically using the 5% LSD test. The results showed no significant interaction between the type and dose of liquid foliar fertilizers on the growth and yield of hydroponically grown pak choy. However, Good Grow fertilizer at a dose of 20 ml/L produced the best results in terms of plant height, shoot-to-root ratio, number and density of stomata, as well as stomatal length and width, compared to Ferti Grow and NPK Vertine.
RESPONSE OF SEVEN VARIETIES OF RICE PLANT WITH GIVE STEM BANANA LIQUID ORGANIC FERTILIZERS AND COCONUT FIBER LIQUID ORGANIC FERTILIZERS ON PLANT GROWTH
Rice is a staple crop that cannot be replaced by other plants in people's lives in Indonesia. Therefore, efforts are always made to increase rice production in the form of intensification, one of which is by providing organic fertilizer so that the fertilizer given is in accordance with plant needs. Organic fertilizer contains complete nutrients, both macro nutrients and micro nutrients. One of the organic fertilizers that can be given is liquid organic fertilizer (LOF) made from natural ingredients such as coconut fiber and banana stems. The raw materials for making LOF are very easy and cheap to obtain because they are widely available in the community. The aim of this research is to obtain lowland rice varieties that respond to banana stem LOF and coconut fiber LOF in increasing rice plant growth. The design used was a Randomized Block Design (RBD) with 7 variety treatments (Bawaan, Bujang Marantau, Cisokan, Inpari Gemah, IPB3S, IR42, and PB42), each treatment was grouped into 4 groups. The observation data was analyzed using the F test at a 5% real level and if significantly different, it was continued with a further DNMRT test at a 5% real level. The results obtained were the growth of lowland rice plants where the seven varieties responded differently to the provision of coconut fiber LOF and banana stem LOF. These results showed that the Bawaan variety responded more to LOF on plant height (86.45cm) and leaf area index (2.97m2/week), and the IPB3S variety responded more to LOF on the number of tillers (61.8 stems).

CHARACTERISTICS OF AGRICULTURAL LAND IN THE FLOODPLAIN AREA OF THE TARUSAN WATERSHED, PESISIR SELATAN, WEST SUMATRA
The numerous rivers and high rainfall in West Sumatra often lead to flooding, which affects several land uses such as settlements, plantations, and agriculture. During floods, water transports various materials from upstream to downstream, such as sand, mud, and clay, which are subsequently deposited in certain areas along the riverbanks. The aim of this study was to examine the soil fertility characteristics in the floodplain area. The method used in this research was a survey method with purposive random sampling at two soil depths: 0 – 30 cm and 30 – 60 cm. Samples were taken from two land uses: dryland agriculture and wetland agriculture. The parameters analyzed were texture, organic carbon, bulk density, total pore space, pH in H2O, available P, total N, and exchangeable potassium. The results of the study for each parameter showed that the soil texture in dryland agriculture was sandy loam, while in wetland agriculture, it was clay loam. Organic carbon for both land uses was classified as low, ranging from 1.31% to 1.62%. Bulk density in dryland agriculture was higher, with values ranging from 1.12 to 1.34 g/cm³, whereas in wetland agriculture, it ranged from 1.01 to 1.10 g/cm³. The total pore space in dryland agriculture was classified as low, ranging from 48.68% to 55.22%, while wetland agriculture had moderate values, ranging from 57.67% to 61.40%. The pH in H2O for all land uses at both depths was classified as acidic, with values ranging from 4.52 to 4.95. Available P in wetland agriculture was classified as very low to low (4.16 to 5.11 mg P2O5/100g), while in dryland agriculture, it ranged from 5.30 to 7.67 mg P2O5/100g, classified as low. Total N in dryland agriculture was classified as low, ranging from 0.13% to 0.18%, while in wetland agriculture, it was classified as moderate, ranging from 0.22% to 0.36%. Exchangeable potassium in dryland agriculture was classified as low, ranging from 0.19 to 0.30 cmol/kg, while in wetland agriculture, it was classified as moderate, ranging from 0.40 to 0.55 cmol/kg. In conclusion, the results of the study indicate that the soil properties, both physical and chemical, in wetland agriculture were better than in dryland agriculture, although no significant differences were found.
Growth response of gambier seedlings (Uncaria gambir (Hunter) Roxb) to the application of Arbuscular Mycorrhiza Fungi (AMF) on ex-coal mine soil
Gambier cultivation development is experiencing constraints on land availability. The use of land for ex-coal mines can be an alternative. Ex-coal mine land has the problem of low available nutrients. Arbuscula Mycorrhiza Fungi (AMF) can help release bound nutrients into available nutrients. The study aimed to determine the effect of AMF type and dose on gambier seedlings planted on ex-coal mine soil growth. The experimental design used a Randomized Complete Design (RCD) using two treatments, namely type of AMF (Acaulospora sp, Glomus sp, and Gigaspora sp) and AMF dose (0, 5, 10, 15, and 20 g/seedling) with three replications. The observation parameters were soil chemical analysis, root colonization by AMF, seedling height and leaf number increase, shoot fresh and dry weight, root fresh and dry weight, shoot root ratio, net assimilation rate, and relative growth rate. The results obtained were that AMF type and dose treatment had a significant effect on all growth parameters except the relative growth rate, and there was no interaction between the two treatments. The type of AMF Glomus sp and a dose of 20 g/seedling provided the best influence in increasing gambier seedlings' growth on the ex-coal mine soil.
The effect of soil block media composition on pakchoi (Brassica rapa subsp. chinensis) seedlings growth
Pakchoi plants are generally grown as seedlings at nursery before transplanting. Seedlings that grow well can increase plant adaptation chances to grow and thrive after transplanting. One of the environmentally friendly seedling methods, soil block seedling, can be an alternative to conventional seedling methods. This study aims to test media composition using soil block seedling method on pakchoi seedlings growth. The experiment was carried out using a randomized complete block design with one factor, soil block seedling media composition (humus soil-hs, cow manure-cm, husk charcoal-hc, proportion in per cent), consisting of four treatment levels (K550, A532, B440, C352) repeated three times. The results showed that, soil block seedling media composition significantly affected germination rate, seedling height at 2-3 WAS, leaf chlorophyll content and root development conditions. Treatment B442 (40% hs, 40% cm, 20% hc) resulted in germination rate reaching 97% and rooting conditions that penetrated the soil block seedling media the most. Treatment A532 (50% hs, 30% cm, 20% hc) produces the highest plant height at 2-3 WAS. Treatment C352 (30% hs, 50% cm, 20% hc) produced the highest chlorophyll content at 6 WAS but was not different from treatment K550 (50% hs, 50% cm, 0% hc).
Google Earth Engine for Land Use Interpretation using Panchromatic and Multispectral Composite Remote Sensing Satellite Imagery with Supervised Classification Approach to Support Food Security in Bogor Regency
Bogor Regency is experiencing various complex problems in its regional development, including due to high population and land conversion. One of the problems was that Bogor experienced a food deficit condition of 52.28% in the 2013-2018 period and was projected to increase by 62% in 2025. The research was conducted by identifying land use in 2013, 2018, and 2023 to see land use changes, including conversion of paddy fields. Land use identification was carried out spatially using panchromatic remote sensing satellite images with a spatial resolution of 15 meters, which were composited with multispectral images with a spatial resolution of 30 meters. The purpose of composite imagery is to obtain better thematic accuracy of land use information by increasing the spatial and spectral resolution of the composite imagery used to 15 meters. Furthermore, land use identification was conducted using training samples and several interpretation keys. Training samples were verified with coordinates from the Indonesian Base Map and land cover maps from the Ministry of Environment and Forestry (KLHK). Land use interpretation results were validated with the Cappa index using KLHK land cover maps and satellite images from Google Earth. The results showed that between 2013 and 2023, paddy fields had the highest conversion of 110,000.25 ha in 2013 to 62,831.89 ha in 2023, or decreased by 15.77%. Cappa accuracy generated by the method is 0.984 for 2013, 0.939 for 2018, and 0.931 for 2023 data. With those methods, this research is expected to be used to identify more accurate land use and support better spatial-based food planning.

Evaluation of high-resolution regional climate model performance over Surabaya metropolitan area using RegCM5 MOLOCH core
As climate change continue to impact weather patterns globally, understanding regional effects has become more important. Traditional global climate model lacks the resolution to capture the dynamics of regional climate, leading to uncertainties in predicting local climate. There has been some research about high-resolution regional climate model, but not specific to Indonesia especially Surabaya. This paper aim is to evaluate the new MOLOCH non-hydrodynamical core of RegCM5 in producing high-resolution regional climate model. This study covers Surabaya Metropolitan Area, with a period of December 2017 to November 2019. Three different scheme combinations were compared, two of which were based on previous research, and one is a new combination. ERA5 0.25° 6-hour surface and sea surface temperature datasets were utilized as the global climate model. It can be observed that the model had a cold bias for the maximum temperature and warm bias for the minimum temperature. As for precipitation and surface upwelling longwave radiation the model performed well, and it had a similar pattern with a small bias. Overall, the MOLOCH core performed well, but the model produced limited temperature variability as opposed to the observed data. The findings might shed light on the future of regional climate modelling.

This study aimed to evaluate the fresh semen characteristics, frozen semen production potential, and frozen semen quality of Toraya buffaloes at the Technical Implementation Unit for Artificial Insemination Services and Semen Production (UPT-PIBPS) Pucak, South Sulawesi, Indonesia. Two bulls, Sopai and Sadoko, were assessed to determine their reproductive potential. Fresh semen analysis showed that Sopai produced the highest number of ejaculates (84), with an average ejaculate volume of 1.88±0.19 mL and sperm concentration of 1133.91±31.13 million/mL. In contrast, Sadoko demonstrated a higher sperm concentration (1466.55±71.35 million/mL) and a greater number of potential straws per ejaculate (78.89) compared to Sopai (59.51). Analysis of frozen semen revealed significantly higher quality in Sopai's semen (p<0.05). The Sopai semen may be better suited for artificial insemination programs emphasizing frozen semen quality and cryopreservation efficiency, while Sadoko's higher sperm concentration and greater straw production potential could be advantageous for large-scale artificial insemination programs requiring high semen output. In conclusion, the fresh semen characteristics, frozen semen production potential, and overall quality of Toraya buffaloes at UPT-PIBPS Pucak meet the standards for frozen semen production. The consistent ejaculate volume, high motility, and adequate sperm concentration highlight their strong potential to support artificial insemination programs in Indonesia.
Antimicrobial-resistant bacteria isolated from clinical mastitis cases
Bovine clinical mastitis is a global problem because it decreases milk quality and quantity. Treatment of bovine clinical mastitis becomes more complicated due to the emergence of antimicrobial resistance of the causative pathogen. The purposes of this study were to identify bacteria from clinical mastitis cases and investigate their antimicrobial resistance. Using standard bacterial culture techniques, bacteria were isolated from milk samples of cattle with clinical mastitis. Identification was performed through colony morphology, Gram-staining, and biochemical assays. Antimicrobial susceptibility was tested against seven antimicrobials using disk diffusion method. Identified bacteria included Escherichia coli, Enterobacter aerogenes, Pseudomonas sp., and Staphylococcus aureus, among others. Multridrug-resistance bacteria were identified. E. coli was resistant to all tested antimicrobials, E. aerogenes was resistant to multiple classes of antimicrobials, particularly beta-lactams and macrolides. Pseudomonas sp. was sensitive only to gentamicin. The S. aureus isolate demonstrated resistance to beta-lactam antimicrobials.
