Abstract

Artemisinin, is a sesquiterpene lactone which is originally extracted from the medicinal plant Artemisia annua L. Artemisinin is a very effective antimalarial agent, however it is produced in very low amounts in plants. Chemical synthesis of artemisinin is complicated and not economically feasible. Researchers often use elicitation methods to increase artemisinin content in a laboratory scale with biotic or abiotic elicitor. This study examined the effect of elicitation using endophytic fungi Aspergillus sp on artemisinin content of callus A. annua cultures. Observations were made on its growth, texture and color, chlorophyll content and dry weight. Fungi were isolated from the stem tissue of A. annua and callus were grown on Murashige and Skoog medium. After 3 weeks of incubation, callus treated with four different elicitors concentration (0, 2, 4, 6 mg/mL). There were significant alterations on callus culture in terms of growth, texture, color and chlorophyll content after elicitation. The results clearly demonstrated that the endophytic fungal elicitor Aspergillus sp could increase artemisinin content but did not affect the callus dry weight of A. annua. The treatment of 4 mg/mL  elicitor produced the highest artemisinin content, that increased 7.6 times compared to the control, from 0.0036% to 0.0275%.

Abstract

Changes in land use have an impact on the level of soil fertility. Soil management, such as land cover systems and the environment, are supporting factors. Assessment of soil fertility index using indicators of soil chemical properties such as organic C, availability of nutrients nitrogen (N), phosphorus (P), cation exchange capacity (CEC), and exchangeable cations (K, Ca, Mg, Na). The research was conducted in Tutur District, Pasuruan Regency, with a survey of 5 land uses, i.e., mixed crops, coffee plantations, apple plantations, vegetable fields, secondary forests, and conservation forests. Observations were made on elevation, slope, and vegetation. Parameters of physical properties measured were soil texture and aggregate stability. Observations of chemical properties included organic C, N, P, CEC, exchangeable cation (K, Ca, Mg, Na), and soil pH. Soil Fertility Index (SFI) data were analyzed using the Least Significant Difference method at a 5% level. The results showed the diversity of soil fertility levels obtained from the calculation of the soil fertility index. The soil fertility index value in 5 land uses in Tutur District ranged from 0.67 to 1.00. Coffee plantations had the highest SFI score of 1.00; this condition was supported by an organic C indicator of 6.21% and a CEC value of 39.12 cmol kg-1. Conservation forest is the land use with the lowest SFI value of 0.67. The value of CEC and cation exchange in conservation forests are factors that impact the low value of SFI.

Abstract

Forest conversion to agriculture systems leads to change on litter input (quantitatively and qualitatively) resulting lower diversity, population density and biomass of earthworm. Litter with ratio C/N <20, or ratio of (lignin (L)+polifenol (P))/N <10 classified as high quality which decomposed rapidly. Six types of litter application were tested i.e. prunning of cofee with the lowest (L+P)/N of 7.5, Gliricidia (L+P)/N of 10, avocado with (L+P)/N of 31, Cofee+Gliricidia with (L+P)/N of 12, Cofee+Gliricidia+ avocado with the highest (L+P)/N of 64. As control soil without litter application was used. Applying tree litters regardless their quality increased significantly (p<0.05) all growth parameters of earthworm, except for Gliricidia application lead to higher level of earthworm mortality starting at 20 days after treatment. Applied a low quality of avocado litter to the soil produced the highest biomass (0.79 g/indiv.), diameter (2.42 mm/indiv.) and length (6.13 cm/indiv.). Mixing coffee litter with Gliricidia litter increased earthworm mortality (5.5% to 42.5%) and reduced production of cocoon (2 become 0 cocoons) compared to coffee applied alone. Coffee+Gliricidia+Avocado lead to longer live earthworm up to 80 days Apparently Gliricidia litter producing chemical substances which harmful to earthworm.Keyword: earthworm, litter quality, forest conversion

Abstract

Organic farming practices are needed to maintain soil fertility and the health of horticultural products on the banks of the Bengawan Solo river in Jangglengan village, Sukoharjo. This community service aims to teach the farming community about organic farming principles and the practice of making liquid organic fertilizer to support healthy horticultural farming on riverbanks in the Jangglengan area. The partner group, the Jangglengan village government, involves 60 farmer representatives. The methods used were focus group discussion, practices for making liquid organic fertilizer, and evaluation. The results of community service activities show that 75% farmers can show good organic waste material for organic fertilizer, and 95% farmers had improved skills and were able to try making fertilizer by themselves. This organic farming socialization is a good start toward implementing good agricultural practices on the land along the Bengawan Solo River in Jangglengan.

Abstract

The characteristics of indigenous bacterial isolates in cocoa farms differ based on the study's location and methodology. More research is required to comprehend these bacterial isolates' diversity and features completely. This study intends to assess the cellulose-degrading capacity of bacterial isolates from cocoa plantations in Meko Village, Central Sulawesi. The shape of the bacterial colony, the shape of the colony's edge, elevation, colony size, color, and texture are considered during macroscopic morphological identification and microscopic morphological identification after gram stain. Afterward, gram stains the bacteria to determine the type of cell wall. Hydrolysis capacity was then identified macroscopically by observing colony shape, colony periphery, colony color, colony appearance and height, and hydrolysis capacity on media in a petri dish (HC). Upon microscopic examination of cell shape and bacterial wall type (Gram-positive and gram-negative). Based on the research findings and identification of bacteria capable of degrading cellulose in cocoa soil, it can be inferred that among the 28 examined isolates, six isolates have the greatest HC index values in KL62 isolates. In contrast, GL66, KL23, and KL62x isolates have medium HC index values.

Abstract

The soil in the upstream Bengawan Solo watershed is at high risk of degradation related to a high erosion rate. Finding the proper crop type with land suitability is critical to protect against further soil degradation. This study aimed to determine the land suitability of white turmeric (Curcuma zedoaria) and the limiting factors in the upstream Bengawan Solo watershed community forest. This research was descriptive-explorative based on a survey of four land map units (LMUs) of Sumberejo village (LMU1, LMU2, LMU3, and LMU4), Batuwarno, Wonogiri. The number of sample points at each LMU depended on the total area of the LMU and was repeated four times. LMU results from overlay soil type maps, administrative maps, rainfall maps, and slope maps. Land suitability assessment was analyzed using the matching method. The land suitability classes of the upstream Bengawan Solo for white turmeric were S3 eh, and N eh. The limiting factors on land suitability for white turmeric are erosion hazards and slopes. The efforts to improve the limiting factor can be made by contour cultivation and repairing the terrace.

Abstract

Water conservation is needed to overcome the shortage of irrigation water through harvesting rainwater on rainfed land using small farm reservoir. Intensive agricultural activities cause a reduction in land resources which disrupts hydrological functions (water quantity and quality). This study aims to determine the selected parameters for small farm reservoir water quality and identify water quality based on irrigation water standards according to FAO (1994) and PP No. 82 of 2001. The research was conducted from March to December 2014 in Karanganyar Regency, Central Java Province. This study used a descriptive exploratory survey method with purposive sampling. Water quality data was analyzed using Principal Components Analysis (Multivariate Test) MINITAB 16 to determine the main components as the selected determinants. Furthermore, based on the results of the PCA analysis, 5 variables were obtained whose eigenvalue proportions met the main criteria, including DHL of 0.467; SAR of 0.542; pH of 0.538; Actual Savings Ratio (ASR) of 0.662; and water-air temperature deviation of 0.612. Furthermore, a match is made between the selected determinant measurement data and the water quality standard. The results of matching to the selected determinants for water quality in the reservoir have met the water quality standards for irrigation based on FAO (1994) and Government Regulation no. 82 (2001). The soil characteristics of the catchment area also affect water quality because in rainwater harvesting, surface runoff in the catchment area will flow and be accommodated by the small farm reservoir.

Abstract

Kebonagung Sub-district, Sidoharjo District, Wonogiri Regency is the Wonoagung Wonogiri Organic Farming Association (PPOWW) location. Mitra is an organization engaged in organic rice and cattle cultivation. The conversion of bovine dung into organic fertilizer, particularly liquid fertilizer containing biological agents, is one of the waste elimination strategies employed to prevent environmental contamination. The nutrient content of organic fertilizer material sources varies. Organic fertilizer of high quality conforms to the Standard for Organic Fertilizers established by the Ministry of Agriculture of the Republic of Indonesia. Only some producers are aware of the standard quality requirements for organic fertilizer. It is necessary to analyze the nutrient content of organic fertilizer products to determine whether the quality of organic fertilizer is excellent. A preliminary survey of partner conditions, preparation of materials (organic fertilizer), and analysis of fertilizer content are among the activities performed. The C/N ratio of organic fertilizer is 8.41, and its pH is 7.6. The analysis results indicate that the Wonoagung Wonogiri Organic Agriculture Association's organic fertilizer products meet the liquid organic fertilizer quality standards. This condition demonstrates that the raw materials used in organic fertilizer production are of high quality and that the appropriate procedures have been followed. Adding biological agents to the production of organic fertilizer can enhance the quality of the finished product.
