Di Jepang, kegiatan pengabdian masyarakat yang dilakukan oleh sukarelawan, seperti kelas bahasa Jepang, sering kali melibatkan ibu-ibu dengan anak kecil, terutama selama jam kerja ketika balita tidak bersekolah. Untuk mendukung belajar, penyelenggara menyediakan fasilitas kegiatan bagi anak, memungkinkan para ibu untuk fokus penuh pada pembelajaran. Pendekatan yang berfokus pada pemberdayaan ibu dan aktivasi anak ini tidak hanya meningkatkan keterampilan dan pengetahuan ibu melalui peningkatan fokus belajar, menjadi daya tarik bagi program, tetapi juga memastikan bahwa anak-anak mereka terlibat dalam aktivitas bermakna yang mendorong perkembangan kognitif dan sosial. Di Indonesia, beberapa kegiatan pengabdian masyarakat yang menargetkan ibu rumah tangga banyak dilakukan, mengingat potensi waktu yang dimiliki dan peran signifikan ibu rumah tangga dalam kontribusi ekonomi keluarga. Ibu rumah tangga di Indonesia juga beberapa mengalami kondisi serupa dengan adanya kegiatan mengasuh anak. Keberhasilan model ini di Jepang menunjukkan efektivitas integrasi antara pemberdayaan ibu dan aktivasi anak, yang berkontribusi pada penguatan keluarga dan ketahanan komunitas. Berdasarkan model di Jepang, pendekatan serupa dapat diterapkan di Indonesia sebagai pilihan yang dapat diimplementasikan sesuai dengan konteks masyarakat Indonesia guna memberikan manfaat yang substansial.

Metabolomics can be applied in a wide range of fields, including bioscience (functional genomics), medical (clinical research or public health), bio-industry (biofuel production), as well as food and agriculture. Metabolomics analysis generates numerous metabolites information which applicable for various purposes. Information related to metabolites can lead to the determination of metabolite markers, metabolic pathways, and modeling processes. Food metabolomics evaluates the food quality resulting from various treatments starting from cultivation, harvesting, post-harvest treatment, and food processing. Food metabolomics combines the metabolomics approach with specific attributes/grades/characteristics of the product to fully elucidate factors contributing the food quality. Metabolomics can complement or determine the grade of food products previously carried out by sensory evaluation resulting in a more effective and efficient determination method. Food metabolomics applications range from increasing shelf life, quality improvement, authenticity assessment, diet monitoring, identifying unique characteristics, and product development. This field of study also contributes to realizing an ethical consumption society and less food loss and waste reduction. Eventually, food metabolomics contributes to SDG 2 (creating a world free of hunger), SDG 3 (ensuring healthy lives and promoting well-being for all at all ages), and SDG 12 (ensuring sustainable consumption and production patterns).

This study used a complete randomized block design factorial with two factors. The first factor was two Brassica subspecies consisting of Brassica rapa subsp. chinensis (Pak Choi) and Brassica rapa var. parachinensis (Choy Sum). The second factor was the concentration level consisting electrical conductivity (EC) 1 mS cm-1 and EC 2 mS cm-1. The results indicated the absorption rates of nitrogen (N,) phosphorus (P), and potassium (K) in leaves, roots and stems were similar in both nutrient concentrations. In general, all combination treatments resulted more accumulation of P followed by N, also K as the smallest proportion. P was mostly accumulated at the root and leaves (19.60 to 25.90 mg g-1), while majority of N was collected in leaves ranging from 18.00 to 24.30 mg g-1. The highest K content was detected in the stem (10.70 to 14.20 mg g-1). P uptake was 1.69 to 2.47 times higher than K, while N uptake was 1.44 to 2.04 times higher than K. Both two subspecies and concentrations performed no significant effects on nutrient uptake. Although same species, the plant growth parameters of Pak Choi and Choy Sum are very different including plant height, leaves number, width and length. Both two subspecies adapted well with both concentrations. However, significant differences were recorded in the combination of subspecies and nutrient concentration on plant growth and production parameters. To achieve higher market portion, Pak Choi would be more suitable to be planted on EC 1 mS cm-1 , while Choy Sum was favorable at both concentrations.

Efforts to increase chili production need fertilization through roots and leaf fertilization. The research aimed to obtain optimum intervals of NPK (nitrogen, phosphor, potassium) fertilization and kinds of foliar fertilizer for the growth and yield of chili. The research was conducted from April to August 2020 in Gayam Village, Sukoharjo Regency, Central Java, Indonesia. This study used an experiential method with a Randomized Complete Block Design (RCBD) of 2 factors. The first factor was an interval of NPK fertilization (16-16-16) with a concentration of 25 g.L-1 with a dose of 240 mL.plant-1. The interval of NPK fertilization consists of 4 levels, NPK fertilizer which was applied every 5, 10, 15, and 21 days. The second factor was foliar fertilizer which consists of A foliar fertilizer, B foliar fertilizer, and C foliar fertilizer. The results showed that the interval of NPK fertilizer affected the number of dichotomous branches, dry stove weight, cumulative fruit, cumulative fruit weight, and fruit length at 1st harvest. NPK fertilization every 15 days increased the dichotomous branches by 23.16%, dry stove weight by 37.98%, cumulative fruits by 37.41%, and cumulative fruit weight by 41.46%. B foliar fertilizer and A foliar fertilizer gave the same performance in dichotomous branches. There was no interaction effect between the interval of NPK fertilization and the kind of foliar fertilizer on all growth and yield variables. NPK fertilization optimum intervals as supplementary fertilizers should be given every 15 days. This research can be used as a reference for farmers in fertilizing chilies.

The process was implemented in an anaerobic condition which produced predominantly phenolics compounds and other complexes’ organic constituents. Base on previous findings, in which allelopathic effects of growing vegetation were sourced by phenolics compounds, the filtrates of the hydrolysates were tested as bioherbicide on Borreria alata as a broadleaf weed. The testing of the weed growth covered the weed response at pre-emergence, early post-emergence, and post-emergence stages. The hydrolysate solution contained phenolic, carboxylic, and ketone groups with a yield of less than 12 mg/kg feedstock after undergoing the thermal hydrolyzation process at subcritical temperature. At the post-emergence stage, coconut shell hydrolysates were capable to suppress the growth of Borreria alata by 13-40% and cause leaf damage at the level of 43-63%. However, its effectivity was higher at the pre-emergence and the early post-emergence stages, where the suppression capacity of shell hydrolysate on the weed growth reached 84-100%.

This study aimed to identify the application of microbe inoculations with dosage of N in form of urea toward the growth, N uptake and yield in soybean. This research was conducted on October 2017 to January 2018 in Panunggalan village, Pulokulon, Grobogan, Central Java. It used the Randomized Complete Block Design 2 factors: urea dosages (0; 50; 100 kg ha−1) and microbe inoculations (no inoculation; Rhizobium (R); Rhizobium + Trichoderma (R+T); Trichoderma(T)). The result showed that combination of urea dosage and microbe inoculations significantly influenced plant height and number of trifoliate leaves. Urea dosages and microbe inoculations or combination of both factors did not imply nodulation process. Higher N dosage and microbe inoculations increased N uptake of biomass on vegetative period but had no effect on flowering and pod filling periods. The combination of 100 kgHa-1 urea with microbes or without microbes produced the highest productivity. However, treatment without urea and no inoculation also achieved the highest production. This suggested that there was a native population of Rhizobium bacteria strains that effectively supplied N for plants. Besides, application of urea of 100 kg ha-1 or 46 N kg ha-1 was too small to interfere fixation nitrogen by local Rhizobium population. Therefore, N application in form of anorganic fertilizer or microbe for symbiotic N-fixation was not recommended for existing agro climatic conditions of area with soybean history. Thus, it could simultaneously save the cost of agricultural production.

Generally geophysics aspect does not support the growth and development of cocoa especially that caused by natural limited factors (water and soil fertility) on suboptimal land. The research propose is to evaluate the role of fertilizer on cocoa production. The soil fertility is in the low level such as C organic, total of N and organic compound as big as 0.63, 4.15, 1.08% respectively and the available of P2O5 is 2.72 part per million. Besides soil properties, there is another constrain which no less important to physical aspect, it is the minimum knowledge of cocoa cultivation especially maintenance aspect such as fertilizer and shoots (chupon) cutting. Fertilization has been applied three times that are after harvest, initiation of flowering and fruit formation at five samples of cocoa at every location which based on the three levels of altitude. The role of fertilizer has been evaluated from nutrition absorption (leaf tissue analysis), number of seeds per 100 g and the content of protein, fat, phenol in seed. The data has been analyzed by F test and be continued by Duncan multiple range test. N, P and K content of leaves are not significant both before (after harvest) and after fertilization (initiation of flowering and fruit formation) and it means that most of the element have distributed for formatting flower and fruit.

The gamma rays can induce mutation in plant. The purpose of this research was to understand the yield and anthocyanin of black rice with gamma ray irradiation using M1 generation from Bantul and Boyolali varieties. This experiment employed 0, 100, 200 and 300 Gy gamma ray irradiation. The effects of gamma rays on Boyolali variety differed from Bantul variety. Bantul variety was more sensitive to gamma rays irradiation than Boyolali variety. The application of gamma rays did not significantly change the flowering age Boyolali variety. However, on Bantul variety, gamma rays reduced flowering age. Application 100 Gy irradiation yielded early maturing plant on Bantul variety. This result revealed that the gamma ray had potential for decreasing the harvest age in black rice. The application of irradiation could enhance the size of grain of black rice indicated by higher weight of 1000 seed in Boyolali variety. Irradiation 100 Gy also boosted yield per plant in Boyolali variety. In Boyolali variety, gamma ray boosted the yield per plant by producing bigger seed rather than increased the number of productive tillers. The increase of the irradiation doses did not always correlate with the changes of plant phenotype. To conclude, application 100 Gy was the most effective dose to produce higher anthocyanin content compared to another doses.

DC.) has the potential to be developed as a medicinal plant. However, this plant is still collected from nature, so this will threaten Valerian germplasm, varying quality and uncertain crop yields. Moreover, the impact of climate change, such as drought and lack of nutrients in the soil, could threaten Valerian’s presence. This research aimed to investigate the tolerance level of Valerian on several water stress levels and influence of organic fertilizer on the plant biomass. This experiment utilized completely randomized design with 2 factors and three repetitions. The first factor was organic fertilizer consisting of no fertilizer (control), cow manure, and goat manure. The second factor was water stress consisting of 100% field capacity, 80% field capacity, 60% field capacity and 40% field capacity. The result depicted that 40% field capacity produced the lowest biomass compared to 60 %, 80 % and 100 % field capacity. In addition, goat manure resulted in higher biomass than cow manure.

Long harvesting age and low productivity are the inhibiting factors in black rice breeding. High plant crown potentially results in plant fall-down. Mutation induction is expected to be able to improve the character of black rice. Therefore, the objectives of this research were to get more early-ripening black rice mutant, with shorter plant crown and increase productivity by inducing mutation in three varieties of local black rice using gamma-ray radiation. This experiment employed three local varieties as the first factor comprised Cempo Ireng, Cempo Melik and Melik. The second factor was the gamma-ray radiation dose, consisting of 4 levels: without radiation, radiations at 100 Gy, 200 Gy and 300 Gy doses. The results indicated that Melik variety is very potential. Melik variety has shorter plant crown with a responsive character in number of tiller for higher productivity. Moreover, radiation significantly reduces the duration of flowering and harvesting. However, to achieve a more stable character and lower flowering and harvesting period, the radiation needs to be continued in the next generation. The doses of radiation produces a response that varies in both morphological and biochemical properties.

This condition is caused by unintensive fertilization and low light intensity caused by shading. The effort to increase cocoa seed quality was by light compensation and the use of nitrogen (N) fertilizer. The purpose of this reseach was to determine of optimum N dosage fertilizer for inproving seed quality. The research was arranged in Completely Randomized Block Design with one factor which is the varies N dosages (0 as control, 820, 870, and 920 gram plant-1 year-1), level of radiation represented as blocks. Nitrogen fertilization was applicated three times. Fertilization of P (SP36) and K (KCl), 1390 and 1000 gram tree-1 year-1 respectively. The observation variables are soil character, micro climate, leaf anatomi, physical and chemical seed quality. The result showed that N fertilizer influenced positively toward increasing potassium (K) content in leaf tissue on the first and second month, while on the third month no significant influence toward N, P and K content. However there was preference of increased N, P and K content in leaf tissue on each month although in small rise number. In the leaves tissue, there was detected that nitrogen proportion was larger than potassium and phosphorus. N fertilizer increased the physical and chemical seed quality (protein and fat content). Optimum dosage was 870 gram tree-1 year-1 , highest weight of 100 seed (146 gram) and seed quality was categorized as grade 1.

The second factor was the concentration level consisting electrical conductivity (EC) 1 mS cm-1 and EC 2 mS cm-1. The results indicated the absorption rates of nitrogen (N,) phosphorus (P), and potassium (K) in leaves, roots and stems were similar in both nutrient concentrations. In general, all combination treatments resulted more accumulation of P followed by N, also K as the smallest proportion. P was mostly accumulated at the root and leaves (19.60 to 25.90 mg g-1), while majority of N was collected in leaves ranging from 18.00 to 24.30 mg g-1. The highest K content was detected in the stem (10.70 to 14.20 mg g-1). P uptake was 1.69 to 2.47 times higher than K, while N uptake was 1.44 to 2.04 times higher than K. Both two subspecies and concentrations performed no significant effects on nutrient uptake. Although same species, the plant growth parameters of Pak Choi and Choy Sum are very different including plant height, leaves number, width and length. Both two subspecies adapted well with both concentrations. However, significant differences were recorded in the combination of subspecies and nutrient concentration on plant growth and production parameters. To achieve higher market portion, Pak Choi would be more suitable to be planted on EC 1 mS cm-1 , while Choy Sum was favorable at both concentrations.

Efforts to increase chili production need fertilization through roots and leaf fertilization. The research aimed to obtain optimum intervals of NPK (nitrogen, phosphor, potassium) fertilization and kinds of foliar fertilizer for the growth and yield of chili. The research was conducted from April to August 2020 in Gayam Village, Sukoharjo Regency, Central Java, Indonesia. This study used an experiential method with a Randomized Complete Block Design (RCBD) of 2 factors. The first factor was an interval of NPK fertilization (16-16-16) with a concentration of 25 g.L-1 with a dose of 240 mL.plant-1. The interval of NPK fertilization consists of 4 levels, NPK fertilizer which was applied every 5, 10, 15, and 21 days. The second factor was foliar fertilizer which consists of A foliar fertilizer, B foliar fertilizer, and C foliar fertilizer. The results showed that the interval of NPK fertilizer affected the number of dichotomous branches, dry stove weight, cumulative fruit, cumulative fruit weight, and fruit length at 1st harvest. NPK fertilization every 15 days increased the dichotomous branches by 23.16%, dry stove weight by 37.98%, cumulative fruits by 37.41%, and cumulative fruit weight by 41.46%. B foliar fertilizer and A foliar fertilizer gave the same performance in dichotomous branches. There was no interaction effect between the interval of NPK fertilization and the kind of foliar fertilizer on all growth and yield variables. NPK fertilization optimum intervals as supplementary fertilizers should be given every 15 days. This research can be used as a reference for farmers in fertilizing chilies.

The process was implemented in an anaerobic condition which produced predominantly phenolics compounds and other complexes’ organic constituents. Base on previous findings, in which allelopathic effects of growing vegetation were sourced by phenolics compounds, the filtrates of the hydrolysates were tested as bioherbicide on Borreria alata as a broadleaf weed. The testing of the weed growth covered the weed response at pre-emergence, early post-emergence, and post-emergence stages. The hydrolysate solution contained phenolic, carboxylic, and ketone groups with a yield of less than 12 mg/kg feedstock after undergoing the thermal hydrolyzation process at subcritical temperature. At the post-emergence stage, coconut shell hydrolysates were capable to suppress the growth of Borreria alata by 13-40% and cause leaf damage at the level of 43-63%. However, its effectivity was higher at the pre-emergence and the early post-emergence stages, where the suppression capacity of shell hydrolysate on the weed growth reached 84-100%.

This study aimed to identify the application of microbe inoculations with dosage of N in form of urea toward the growth, N uptake and yield in soybean. This research was conducted on October 2017 to January 2018 in Panunggalan village, Pulokulon, Grobogan, Central Java. It used the Randomized Complete Block Design 2 factors: urea dosages (0; 50; 100 kg ha−1) and microbe inoculations (no inoculation; Rhizobium (R); Rhizobium + Trichoderma (R+T); Trichoderma(T)). The result showed that combination of urea dosage and microbe inoculations significantly influenced plant height and number of trifoliate leaves. Urea dosages and microbe inoculations or combination of both factors did not imply nodulation process. Higher N dosage and microbe inoculations increased N uptake of biomass on vegetative period but had no effect on flowering and pod filling periods. The combination of 100 kgHa-1 urea with microbes or without microbes produced the highest productivity. However, treatment without urea and no inoculation also achieved the highest production. This suggested that there was a native population of Rhizobium bacteria strains that effectively supplied N for plants. Besides, application of urea of 100 kg ha-1 or 46 N kg ha-1 was too small to interfere fixation nitrogen by local Rhizobium population. Therefore, N application in form of anorganic fertilizer or microbe for symbiotic N-fixation was not recommended for existing agro climatic conditions of area with soybean history. Thus, it could simultaneously save the cost of agricultural production.

Generally geophysics aspect does not support the growth and development of cocoa especially that caused by natural limited factors (water and soil fertility) on suboptimal land. The research propose is to evaluate the role of fertilizer on cocoa production. The soil fertility is in the low level such as C organic, total of N and organic compound as big as 0.63, 4.15, 1.08% respectively and the available of P2O5 is 2.72 part per million. Besides soil properties, there is another constrain which no less important to physical aspect, it is the minimum knowledge of cocoa cultivation especially maintenance aspect such as fertilizer and shoots (chupon) cutting. Fertilization has been applied three times that are after harvest, initiation of flowering and fruit formation at five samples of cocoa at every location which based on the three levels of altitude. The role of fertilizer has been evaluated from nutrition absorption (leaf tissue analysis), number of seeds per 100 g and the content of protein, fat, phenol in seed. The data has been analyzed by F test and be continued by Duncan multiple range test. N, P and K content of leaves are not significant both before (after harvest) and after fertilization (initiation of flowering and fruit formation) and it means that most of the element have distributed for formatting flower and fruit.

The gamma rays can induce mutation in plant. The purpose of this research was to understand the yield and anthocyanin of black rice with gamma ray irradiation using M1 generation from Bantul and Boyolali varieties. This experiment employed 0, 100, 200 and 300 Gy gamma ray irradiation. The effects of gamma rays on Boyolali variety differed from Bantul variety. Bantul variety was more sensitive to gamma rays irradiation than Boyolali variety. The application of gamma rays did not significantly change the flowering age Boyolali variety. However, on Bantul variety, gamma rays reduced flowering age. Application 100 Gy irradiation yielded early maturing plant on Bantul variety. This result revealed that the gamma ray had potential for decreasing the harvest age in black rice. The application of irradiation could enhance the size of grain of black rice indicated by higher weight of 1000 seed in Boyolali variety. Irradiation 100 Gy also boosted yield per plant in Boyolali variety. In Boyolali variety, gamma ray boosted the yield per plant by producing bigger seed rather than increased the number of productive tillers. The increase of the irradiation doses did not always correlate with the changes of plant phenotype. To conclude, application 100 Gy was the most effective dose to produce higher anthocyanin content compared to another doses.

DC.) has the potential to be developed as a medicinal plant. However, this plant is still collected from nature, so this will threaten Valerian germplasm, varying quality and uncertain crop yields. Moreover, the impact of climate change, such as drought and lack of nutrients in the soil, could threaten Valerian’s presence. This research aimed to investigate the tolerance level of Valerian on several water stress levels and influence of organic fertilizer on the plant biomass. This experiment utilized completely randomized design with 2 factors and three repetitions. The first factor was organic fertilizer consisting of no fertilizer (control), cow manure, and goat manure. The second factor was water stress consisting of 100% field capacity, 80% field capacity, 60% field capacity and 40% field capacity. The result depicted that 40% field capacity produced the lowest biomass compared to 60 %, 80 % and 100 % field capacity. In addition, goat manure resulted in higher biomass than cow manure.

Long harvesting age and low productivity are the inhibiting factors in black rice breeding. High plant crown potentially results in plant fall-down. Mutation induction is expected to be able to improve the character of black rice. Therefore, the objectives of this research were to get more early-ripening black rice mutant, with shorter plant crown and increase productivity by inducing mutation in three varieties of local black rice using gamma-ray radiation. This experiment employed three local varieties as the first factor comprised Cempo Ireng, Cempo Melik and Melik. The second factor was the gamma-ray radiation dose, consisting of 4 levels: without radiation, radiations at 100 Gy, 200 Gy and 300 Gy doses. The results indicated that Melik variety is very potential. Melik variety has shorter plant crown with a responsive character in number of tiller for higher productivity. Moreover, radiation significantly reduces the duration of flowering and harvesting. However, to achieve a more stable character and lower flowering and harvesting period, the radiation needs to be continued in the next generation. The doses of radiation produces a response that varies in both morphological and biochemical properties.

This condition is caused by unintensive fertilization and low light intensity caused by shading. The effort to increase cocoa seed quality was by light compensation and the use of nitrogen (N) fertilizer. The purpose of this reseach was to determine of optimum N dosage fertilizer for inproving seed quality. The research was arranged in Completely Randomized Block Design with one factor which is the varies N dosages (0 as control, 820, 870, and 920 gram plant-1 year-1), level of radiation represented as blocks. Nitrogen fertilization was applicated three times. Fertilization of P (SP36) and K (KCl), 1390 and 1000 gram tree-1 year-1 respectively. The observation variables are soil character, micro climate, leaf anatomi, physical and chemical seed quality. The result showed that N fertilizer influenced positively toward increasing potassium (K) content in leaf tissue on the first and second month, while on the third month no significant influence toward N, P and K content. However there was preference of increased N, P and K content in leaf tissue on each month although in small rise number. In the leaves tissue, there was detected that nitrogen proportion was larger than potassium and phosphorus. N fertilizer increased the physical and chemical seed quality (protein and fat content). Optimum dosage was 870 gram tree-1 year-1 , highest weight of 100 seed (146 gram) and seed quality was categorized as grade 1.
