Abstract

Private forest development has a strategic objective, namely to supply logs as raw materials for the timber industry. The research was conducted in the Keduang Sub-watershed, Wonogiri District. The research objective was to determine suitable tree species and locations for Private forestdevelopment using a Geographical Information System (GIS). The parameters used were production age, soil texture, elevation, and type of production (wood, Multi-Purpose Tree Species / MPTS). Soil types in the Keduang sub-watershed are Litosol (Entisols), Latosol (Inceptisols), and Mediterranean (Ultisols). To determine suitable tree species and locations for Private forestdevelopment, an overlay (with a GIS tool) is carried out between the soil texture map, elevation map, and land cover/use map. Based on the land cover/use map, the area of land suitable for Private forest development is 4,011.95 ha consisting of scrubs (215.51 ha), fields/moor (3,639.84 ha), rainfed fields (114.68 ha), and pasture (41.92 ha). The results of the contour map analysis show that most of the study area has an altitude of <500 m asl (lowland), which is an area of 24,538.02 ha. The soil texture in the study location was dominated by loam, covering an area of 32,153.85 ha. The results of the plant suitability analysis showed that the study location was suitable for Private forestplants such as Acacia mangium, Azadirachta indica A. Juss, Melia azedarach, Paraserianthes falcataria, A. scholaris, Gmelina arborea, Erythrina variegata, Duabanga moluccana, and Hibiscus macrophyllus. While MPTS plants are Aleurites moluccanus and Ceiba pentandra.

Abstract

East Nusa Tenggara Province has land that tends to be dry, with several superior local fruit commodities such as oranges, mangoes, avocados, and jackfruit. One of the local fruit-producing centers in East Nusa Tenggara is North Central Timor (TTU) Regency. Most of the fruit needs in TTU Regency are supplied from West Miomaffo District, especially Saenam Village. Saenam Village produces 222 Kg of local fruit while Sallu Village is 345 Kg, but the sales volume value of Saenam Village is higher than Sallu Village with a difference of Rp. 1,000,000. Based on these conditions, this study focuses on the comparison of local fruit farming businesses in Saenam Village and Sallu Village. The purpose of this study is to compare and analyze the sales volume, relative market share level, and business position of local fruit commodities by applying BCG analysis. The results showed that the fruit business in Saenam Village had a total sales volume in 2018 of IDR 2,151,313, 2019 of IDR 1,915,296, and 2020 of IDR 2,175,685. Meanwhile, Sallu Village has a total sales in 2018 of Rp 1,009,821, 2019 Rp 899,584, and 2020 Rp 887,281. The market growth rate and relative market share are calculated based on the total sales volume. The results of the BCG analysis show that Saenam Village is in the star quadrant, with a market growth rate of 1.31% and a relative market share level of 2.57. Sallu Village has a market growth rate of -15.25% and a relative market share rate of 0.4. This value explains that the fruit products of Sallu Village are in the dog quadrant. The strategy that needs to be carried out by farmers in Saenam Village is to expand fruit marketing. The strategy that can be applied by farmers in Sallu Village is to replace fruit gardens with vegetable gardens in order to increase income and use land more optimally.

Abstract

Palm oil is Indonesia’s competitive advantage in the international commodity market. Various derivative products are produced by palm oil. However, the European policy banning palm oil exports has become an obstacle to Indonesia’s palm oil export performance. Environmental issues are the reason for the ban on imports of Indonesian palm oil. However, in this research, we try to extend the view of sustainable issues. This study uses Indonesian palm oil exports and the European rapeseed oil trade to explain this issue. In this study, we try to explain a pure European policy of sustainability or protectionism. Based on the analysis results, it was found that this policy was strongly influenced by exports and production of European rapeseed oil. The effect of rapeseed oil production on palm oil imports proves that this policy has an element of protectionism to protect European rapeseed plants

Abstract

Many factors cause the issue of fertilizer subsidies. One of them is about the implemented system has not been running optimally. The Farmer Card is an innovation to obtain subsidized fertilizers. The innovation has many obstacles, including the lack of awareness and knowledge of farmers’ human resources (HR) in understanding the innovations’ usefulness. The study’s objective was to determine the factors influencing the acceptance of the Farmer Card based on the Technology Readiness and Acceptance Model (TRAM). Primary data were gained from the farmers by taking a simple random sampling method using the Hair formula for as many as 115 farmers using Farmer Card in Kabupaten Sumenep. The data were analyzed using the quantitative descriptive method through the Partial Least Square (PLS) technique. The study’s objective was to determine the effect of optimism, innovativeness, discomfort, insecurity, perceived usefulness, and perceived ease of use on behavioral intention to use in technology readiness with a p-value of 0.000 (<0.05). The test results show that the variables of optimism (H1 and H2), discomfort (H5), perceived usefulness (H9), and perceived ease of use (H10) have a significant effect on behavioral intention to use Farmer Card. Testing the effect of innovativeness (H3 and H4), discomfort (H6), and insecurity (H7 and H8) showed a p-value of 0.091; 0.259; 0.127; 0.853; 0.385 (> 0.05) means that it has no significance. For the Farmer Card program to be successful, it is recommended to enhance cooperation further and shared views among the farmers and stakeholders.

Abstract

Purwaceng (Pimpinella alpina) is an herbal plant that has aphrodisiac, diuretic, and tonic properties. The imbalance between the growth and the exploitation of this plant makes it included in Appendix I (endangered), so its conservation will be crucial. One method of the conservation of this plant is tissue culture. This method is considered one way to induct the callus. The research objective is to find the effect of various treatments of plant growth regulator concentrations of NAA. 2,4 D and its combination with BAP on the growth of purwoceng callus. Concentration of plant growth regulator NAA (0.5 mg L-1, 1 mg L-1, 2 mg L-1), 2,4-D (0.4 mg L-1, 0.8 mg L-1, 1.2 mg L-1 ), a combination of NAA with BAP (0.5 mg L-1 NAA: 1 mg L-1 BAP, 1 mg L-1 NAA: 2 mg L-1 BAP, mg L-1 NAA: 3 mg L-1 BAP) and a combination of 2, 4- D with BAP (1 mg LL 2,4-D : 0.5 mg L BAP, 1 mg L-1 2,4-D : 1 mg L-1 BAP, 2 mg L-1 2,4-D : 1 mg L-1 BAP) into Murashige Skoog medium. Then purwaceng leaf explants were planted on the medium until the growth was seen. This research shows that the plant growth regulator concentration has a different influence on the growth of callus that is recognized by the day of callus induction, colour and callus texture. MS media with growth regulator 1.2 mg L-1 2,4-D can grow callus faster (17 days) with friable texture.

Abstract

One of the efforts to increase the production of oil palm flower bunches in ultisols is applying biofertilizers and inorganic fertilizers. Biofertilizers can reduce the use and adverse effects of inorganic fertilizers. Arbuscular Mycorrhizal Fungi (AMF) is one of the biofertilizers that can help plants absorb nutrients and increase plant resistance to various environmental stresses. This study aimed to examine the role of AMF (as biofertilizer) and inorganic fertilizers in increasing the production of oil palm flower bunches in Ultisol. This experiment is a factorial experiment using a Randomized Block Design. The first factor is the application of biofertilizers, which consists of two levels without biofertilizers (AMF) and with biofertilizers (AMF). The second factor is the dose of inorganic fertilizer, composed of 5 levels, no inorganic fertilizer, 25, 50, 75, and 100% recommended doses of inorganic fertilizer. The variables observed were the number of sheaths, the percentage of broken sheaths, the number of male flower bunches, the number of female flower bunches, the percentage of male and female flower bunches, sex ratio per plant, and AMF colonization. The results showed that AMF biofertilizer saved 25% of inorganic fertilizers and increased 29.33% of female flowers production. The highest production of oil palm flower bunches was obtained from the application of AMF biofertilizer and 75% of inorganic fertilizers (1.5 kg Urea, 1.1 kg SP-36, 1.2 kg MOP, 0.7 kg Kisserite per plant). Oil palm with AMF had a higher average sex ratio than plants without AMF biofertilizers. The average sex ratio in oil palm plants applying AMF biofertilizer and inorganic fertilizers ranged from 0.42 to 0.73.

Abstract

Tomato (Lycopersiconesculentum Mill. cv. Rampai) is rich in lycopene, a carotenoid group compound with many biological activities, one of which is as an antioxidant. Conventional tomato cultivation is not optimal due to the susceptibility of tomato plants to pests and diseases, even though the need for lycopene continues to increase. Plant tissue culture method can be one solution for lycopene production. Callus tomato cv. Rampai was initiated from cotyledons on MS medium (Murashige& Skoog) with the addition of 1 ppm BA (benzyladenine) and 1.5 ppm IAA (indole-3-acetic acid). Callus aged one week to four weeks were harvested and lycopene was extracted by maceration method using hexane:acetone (9:1) as solvent. The presence of lycopene in callus was confirmed by TLC (thin-layer chromatography) (retention factor value/Rf = 0.56) and UV-Vis spectrophotometry (wavelength that gives maximum absorbance = 472 nm). Lycopene content in tomato callus increased with increasing callus age and was directly proportional to the callus growth index. The highest lycopene level was found in callus aged 4 weeks, which was 0.3094 mg/100 g dry weight callus.
