Abstract

Marlina N, Aminah IS, Amir N, Rosmiah R. 2019. Application of organic fertilizer types to NPK nutrients levels and soybeans production (Glycine max (L.) Merril) at different planting spaces in tidal land. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):148-158.  Tidal lowlands flood type C is suboptimal land and very potential in cultivating soybean, but it has problems in soil fertility, macro and micro nutrient poor, therefore to increase soil fertility can be given various types of organic fertilizers, including cow manure organic fertilizer, chicken manure organic fertilizer and biofertilizer. All types of organic fertilizers are composted, and specifically biofertilizers are made with their own formula. It is expected that the organic fertilizer provided can increase soil fertility and nutrient availability for soybean plants. This study aimed to get the best type of organic fertilizer on the availability of nutrient levels of NPK and soybean production at different spacing in tidal land.  This research was conducted in Jaya Agung Village, Lalan District, Musi Banyuasin Regency, South Sumatra Province, and was carried out in March 2018 - June 2018. The method used was the experimental method. The design used is a split-plot design. with 9 treatment combinations and repeated 3 times. As the main plot treatment is plant spacing (20 cm x 20 cm, 20 cm x 30 cm and 20 cm x 40 cm), and treatment of subplots are: types of cow manure organic fertilizers  10 ton/ha, chicken manure organic fertilizer 10 ton/ha, and biofertilizer 400 kg/ha. The results showed that the combination treatment of plant spacing of 20 cm x 30 cm with the type of biofertilizer 400 kg/ha could  increase   soybean production by 9.11 g/plot or equivalent to 2.43 ton/ha.

Abstract

Rianosa R, Hartal H, Setyowati N. 2020. Effectiveness of the Ageratum (Ageratum conyzoides) leaf extract as botanical fungicide against moler diseases of shallot. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 1-10.  Moler is a major disease of onion caused by Fusarium oxysporum f. sp. cepae. Application of synthetic fungicides in the long-term has a negative effect to the environment. Weed leaves of Ageratum (Ageratum conyzoides) have potential to be an anti-fungal, anti-bacterial as well as anti-cancer. This study aimed to determine the best concentration of Ageratum leaf extract to control twisted disease and to compare the effectiveness of botanical fungicide and synthetic fungicide. The research was conducted in June - September 2018 at the Plant Protection Laboratory and greenhouse, University of Bengkulu. The experiment was consists of five Ageratum leaf extract concentrations as a botanical fungicide (i.e. 1%, 2%, 3%, 4%, and 5%), and synthetic fungicide namely mancozeb and metil tiofanat and control treatment (in sterile soil with no fungicide treatment). The experiment used Completely Randomized Design (CRD) with a single factor. Ageratum leaf extract was obtained through the maceration method using ethanol 96%. The application of fungicide was carried out on shallot bulbs before planting. The results showed botanical fungicides from Ageratum leaf extract were effective against twisted disease of shallots, concentration 4% of Ageratum leaf extract resulted in a longer incubation period and lower disease intensity compared to other concentrations, and the effectiveness of Ageratum leaf extract at a concentration of 4% was comparable to that of mancozeb to control twisted disease. Application of both synthetic and botanical fungicide resulted in a higher yield of shallot. Therefore, Ageratum leaf extract has potential as a substitution of synthetic fungicides to control twisted disease of shallots.

Abstract

Amirrullah J, Hutapea Y, Ratmini NPS, Prabowo A. 2020. Farmer mentoring in determining fertilization dosage of corn plants (Zea mays L.) using soil test equipment. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 102-108.Balanced fertilization is very important to do in marginal soils. The constraints in the use of marginal soils are physical, chemical and biological soil characteristics which do not support planting growth. Determination of fertilizer dosage for corn commodity in one region can be different depending on the available nutrient content that testing needs to be carried out. This study aimed to mentor farmers in taking appropriate soil samples and determined fertilizer doses according to location specifications and application of fertilizers on target using the Dry Soil Test Kit (Perangkat Uji Tanah Kering). This activity was carried out in Fajar Jaya Village, Ogan Komering Ulu District in February 2019.  The results of the soil analysis of the location used as a demonstration plot derived from the results of low soil fertility analysis with soil acidity at pH 4-5 with acid crystals, moderate P, K and C-organic nutrients were relatively low. The recommended fertilizer is as follows: urea 325 kg/ha given 3 times, one-third the dose, carried out 1 MST, 4 MST and 6 MST; TSP 200 kg/ha; KCl 125 kg/ha; 5,000 kg/ha of compost and 1,000 kg/ha of lime stocked during tillage 1 week before planting. Fertilization application method applied by farmers is not in accordance with the recommendations; consequently, it is necessary to fertilize to increase nutrient content.

Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):192-201.  This study aimed to analyze the level of family welfare as a result of the empowerment of women through the Women Farmers Group. The analytical method was carried out descriptively by tabulating data, then analyzed by comparing with the reference level of the prosperous family and its indicators based on the conditions set by the BKKBN. To analyze the impact of women's empowerment on household economic behavior, it was carried out using multiple linear regression analysis. Sampling was carried out by a simple random sampling method of 60 housewives who were members of the Wanita Tani Group. The results of this study indicated that when viewed from the indicators set by the BKKBN, the majority of Women Farmers Households were in the Prosperous Family II category. Simultaneously, the variable intensity of the participants, the number of family members, the age of the mother, the level of education of the mother had a significant effect on the level of income, maternal work time, and household consumption in the City of Prabumulih. But partially, the intensity of the participants had a significant effect on time spent working and household expenses, while on household income was not significant.

Abstract

Manalu A. 2020. Community based peat conservation. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 11-22.Peat forms naturally in swamp areas when dead plants rot and accumulate, which then decompresses and accumulates within hundreds to thousands of years. Peat can store 20 times more carbon than mineral soil. Indonesia's peatlands store about 46 Gt of carbon or around 8-14% of world peat carbon (Maltby and Immirizi, 1993). Peat has an important ecosystem that acts as a protector of the Earth's atmosphere from the greenhouse effect, ecological buffer, saves biodiversity and a place to live for various flora and fauna. Peat have the ability to resemble sponges which make them suitable as water catchment areas. The purpose of this study is to provide an overview of the importance of protecting and maintaining peatlands as protectors of the Earth's atmosphere, controlling global climate by involving the community. This research was conducted with qualitative descriptive methods taken from various literature and national media. The results showed that land degradation has occurred due to the extensive conversion of peatlands into plantations which in the process of causing environmental damage and peat ecosystems in various regions of Indonesia. For this reason, community-based peat conservation needs to be done so that sustainability is maintained and the community gets economic benefits from peatlands.

Inonu I, Kusmiadi R, Yuliana A, Nurtjahya E. 2020. The amelioration of post tin mining sand tailing medium with chicken manure for pepper cultivation. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 31-40. Pepper cultivation in tin mining sand tailings requires the amelioration of organic matter to improve soil characteristics. The paper investigates the effect of chicken manure dosage on the growth of three pepper cultivars in sand tailing medium. This study was conducted on April-August 2016 at Experiment Station of Universitas Bangka Belitung, Balunijuk Village, Bangka Island. This study was arranged in a completely randomized design with two factors and three replications. The first factor was the dosage of chicken manure (5 kg; 6 kg; 7 kg/plant). The second factor was pepper cultivars (Lampung Daun Lebar; Lampung Daun Kecil; Merapin). The. result of the analysis of variance showed that the treatment of chicken manure dosage significantly affected only on total leaf area. The treatment of pepper cultivars significantly affected the total of chlorophyll, root dry weight, and shoot dry weight. There was no interaction between chicken manure dosage and pepper cultivar. Pepper cv. Lampung Daun Lebar tends to grow better than the other cultivars in the sand tailing medium.
