Abstract

The importance of the presence of bioactive compounds that have the potential as antioxidants from various medicinal plants has become a topic that is often discussed by several researchers today. One of the higher-classification plants that potentially has antioxidant activity is the mango parasite (Dendrophthoe pentandra (L.) Miq), classified as a parasite of the Loranthaceae family. The use of specific endophytic fungi microbes from mango parasites of leaf tissue is expected to produce several bioactive compounds that act as antioxidants needed for large-scale production in a short time without excessive exploitation of nature. This primary research aims to determine the potential antioxidant activity of endophytic fungi extracts from the parasite of mango leaves Integrated Microbiology Laboratory and Halal Center of the Islamic University of Malang. Antioxidant testing using DPPH (2,2-diphenyl-1-picrylhydrazyl) free-radical capture of activity method. The results showed that KEDBM 1 (Aspergillus spp.) isolates had no potential antioxidant activity. While KEDBM 2 (Aspergillus spp.) isolate has the highest antioxidant potential with an IC50 value of 13.71 μg/ml and KEDBM 3 (Colletotrichum spp.) has a high potential as an antioxidant with IC50 of 36.29 μg/ml.Key words: antioxidant, mango balu, DPPH, endophyte

Abstract

The growth of the human population has resulted in the conversion of agricultural land into residential areas, and one potential solution to this issue is utilizing hydroponic technology for agriculture. The Smart Watering SWU02 hydroponic system is one type of hydroponic technology that can be employed for this purpose. Proper spacing plays a crucial role in hydroponics because it can impact plant growth and development. Therefore, the objective of this study was to examine the impact of spacing on the growth and yield of green butterhead lettuce (Lectuca sativa var. capitata L.). A completely randomized design (CRD) with three treatments, consisting of 12.5 x 12.5 cm, 20x20cm, and 25 x 25 cm spacing, each replicated three times, was used in this study. The results demonstrated that plant spacing significantly affected plant growth and yield. Planting lettuce with a spacing of 25 x 25 cm resulted in the best outcomes and had a significant impact on plant growth and yield compared to other spacing options, with a plant height growth of 18.33 cm, a plant width of 31.17 cm, a yield of plant weight of 122.78 grams, and a distance between leaves of 0.03 cm. Optimal plant growth and avoiding etiolation symptoms can be achieved by spacing plants apart, which minimizes competition for nutrients.Keywords: Green Butterhead Lettuce., Hydroponics, Planting Spacing, Plant Yield

Abstract

The utilization of organic waste in Indonesia has not been fully optimized, but one technique that can be used is bioconversion, which involves the use of organisms such as the maggot black soldier fly (Hermetia illucens) to convert the waste. Organic waste sources, such as molasses and tofu dregs, can be used for this purpose. The aim of this study was to investigate the growth of BSF maggots using molasses and tofu dregs media. A completely randomized design (CRD) with four treatments and six replications was used, including a control treatment using fruit and vegetable waste (P0), 100% molasses (P1), 50% molasses and 50% tofu dregs (P2), and 100% tofu dregs (P3). The data were analyzed using the SPSS program, and the results indicated that the P0 treatment produced the highest weight and length of 0.13 grams and 17 millimeters, respectively. Further analysis using DMRT showed that P0 was the best medium for maggot growth. The treatment with the highest maggot nutritional content was P0, with 9.57% protein and 5.99% fat. The treatment with the highest carbohydrate content was P2, at 22.04%. Future research can investigate other media and ratios to further optimize the growth of the maggot black soldier fly (Hermetia illucens).Keywords: growth, fruit and vegetable waste, maggot, molasses, tofu dregs

Abstract

The role of institutions is crucial in the hydroponic vegetable agribusiness subsystem, encompassing input procurement to marketing to enhance product quality and value. However, the institutions in the hydroponic vegetable agribusiness system in Tarakan City have not shown a significant role, indicating the non-functional institutionalization of related institutions. This has led to both horizontal and vertical sectoral egos and conflicts between institutions. This research uses a systems approach to identify and study the institutions involved and the structural model of the hydroponic vegetable agribusiness institution. The research method used was descriptive qualitative with Interpretative Structural Modeling (ISM) data analysis techniques. Purposive sampling was utilized for data collection. The findings reveal that institutions that should have a role in hydroponic vegetable agribusiness are the Food Security and Agriculture Department, Agricultural Extension, Middlemen, Cooperative Department, Small and Medium-sized Enterprises (SMEs), Industry and commerce Department, Cooperatives, Banks, Association of Farmers Groups, Farmer Group, Agricultural Shops, and Central of Bureau of Statistics. The institutions' roles include policy-making, facilitation, provision of farming inputs and infrastructure, financial services, lending, selling, marketing, and processing of products. The structural model of the institution's involvement in hydroponic vegetable agribusiness in Tarakan City consists of four levels, with the Key Actor Institution at Level 1, including the Food Security and Agriculture department, Agricultural Extension, Middlemen, Farmer Groups, and Agricultural Shops. The fifth institution is expected to be a driving force in hydroponic vegetable agribusiness.Keywords: Hydroponics, Structural Model, Role of Institutions

Abstract

Pakcoy and Chinese cabbage can only last up to 3-4 days. One method to increase the shelf life and maintain the quality of these commodities is with proper packaging and storage techniques. In this study, the effect of the type of packaging on the shelf life and damage that occurs in pakcoy and Chinese cabbage commodities will be studied. This study used a Rancangan Acak Lengkap (RAL) with the type of packaging treatment factor. There are four types of packaging used, namely PP (Polypropylene Plastic), PE (Polyethylene Plastic), plastic wrappig and opaque paper. From the research results, it is known that packaging can maintain the quality or quality of mustard greens and pakcoy during storage. Chickpeas samples packaged with PP plastic experienced the lowest weight loss of 0.3%. Meanwhile, the unpackaged Chinese cabbage samples (control) experienced a weight loss of up to 43%. Pakcoy vegetables packaged in PE plastic packaging experienced the lowest weight loss of 9.1%. The unpackaged Chinese cabbage samples (control) experienced the highest weight loss, reaching 9.3%. This indicates that the packaging treatment was able to suppress damage and weight loss in Chinese cabbage and pakcoy.Keywords: Chinese cabbage, packaging, Polypropilene Plastic, Polyethylene Plastic.

Abstract

In the hydrological cycle, the rain falling on the ground surface in a watershed (DAS) then undergoes a process of evaporation, infiltration, and surface runoff. This conversion of rain into runoff surface can be used as a basis for calculating the discharge of the design flood. Analyzing flood design is one of the calculations in water resource planning. River flow discharge is an indicator of the output of a watershed system, especially in the process of converting rainfall into a surface flow. Flood discharge in a watershed is generally expressed as a hydrograph. One method that can be used to analyze the conversion of rain into flow is the HEC-HMS software. The purpose of this research is to determine the design of flood discharge and flow hydrograph of Tojo River using HEC-HMS software. In this article, the HEC-HMS model components used to analyze hydrographs are SCS CN for the runoff volume model and SCS UH for the direct runoff model. From the results of modeling using HEC-HMS, the peak flow discharge of the Tojo watershed in Central Sulawesi are 133.8 m3/s for a 2-year design flood, 239.8 m3/s for a 5-year design flood, 329.5 m3/s for 10-year design flood, 442.5 m3/s for 20-year design flood, 589.8 m3/s for 50-year design flood and 727.1 m3/s for 100-year design flood. Furthermore, the results of this study can be used for flood control planning and other water resource planning.Keywords: Flood Design, Das Tojo, HEC-HMS

Abstract

The primary objective of this research was to investigate the efficacy of a combination of soil ameliorants, specifically oil palm shell biochar and tithonia compost, in enhancing the hydrological response of Ultisols and increasing corn yields. The study aimed to identify the optimal dosage combination that would significantly impact Ultisol hydrological response and maize yield. The randomized block design (RBD) was utilized to conduct the study. The ameliorant materials consisted of oil palm shell biochar and tithonia compost, which were divided into six treatments and four groups, including without Biochar and compost (p0), 10 tonnes/ha of Biochar (p1), 7.5 tonnes/ha of biochar 2.5 tonnes/ha of compost (p2), 5 tonnes/ha of biochar 5 tonnes/ha of compost (p3), 2.5 tonnes/ha of Biochar + 7.5 tonnes/ha (p4), and 10 tonnes/ha of compost (p5). Soil physical parameters, such as soil organic matter, soil bulk density, total pore space, soil texture, permeability, infiltration rate, and soil infiltration capacity, were monitored during the study. The BNJ test with a 95% confidence level was used to analyze the research data. The result of the study indicated that the p3 treatment (5 tonnes/ha of Biochar and 5 tonnes/ha of compost) and the p4 treatment (7.5 tonnes/ha of compost 2.5 tonnes/ha of Biochar) demonstrated a more significant improvement in infiltration rate and capacity, as well as soil permeability, compared to the other treatments. Moreover, the p3 treatment (5 tonnes/ha of biochar 5 tonnes/ha of compost) was shown to enhance corn yields by 80.53%, while the p4 treatment (2.5 tonnes/ha of biochar 7.5 tonnes/ha of compost) resulted in an 80% increase in yields.Keywords: Biochar; compost; infiltration; palm shells; tithonia; Ultisol

Abstract

Tana Tidung Regency is predominantly an agricultural area, with around 61.51 percent of the total land area of the district dedicated to agricultural purposes, which amounts to 297,028.7 hectares. Despite having an FDS(Final Disposal Site) that spans roughly four hectares and is managed through a sanitary landfill system, the region still uses an open dumping system. The organic waste found in the FDS can be converted into compost, which can be utilized to fulfill the fertilizer needs of farmers in the Tana Tidung Regency. The primary aim of this study is to determine the compost production potential in Tana Tidung Regency. The research was conducted from May 2022 to January 2023, relying solely on secondary data. The secondary data utilized was waste pile data from the last five years, obtained from the Waste Sector of the Tana Tidung Regency Environmental Department. The data on waste is presented in graphical form, while the compost data projection analysis employs the provisions of Zulfinar and Sembiring (2015) in three scenarios: pessimistic, moderate, and optimistic. Based on the study's findings, the volume of waste generated in Tana Tidung Regency in 2022 will amount to 24,675,825 liters, with a total landfill of 24,676 tons. In the pessimistic scenario, no waste processing into compost will occur in 2022, while the moderate scenario estimates 17,273 tons, and the optimistic scenario estimates 19,741 tons.Key words: Compost, Moderate, Optimistic, Organic, and Pessimistic
