Factors Motivating the Adoption of Geographical Indication-Based Quality Standards among Robusta Coffee Farmers in Indonesia

Robusta coffee is one of the superior commodities of the Temanggung Regency. As the quality of a coffee determines its market competitiveness, geographical indications (GIs) are one of the quality standards used in coffee cultivation and post-harvest processing to indicate the quality of a good Robusta coffee. However, most Robusta coffee farmers in Indonesia do not practice the production methods required to meet these standards. Therefore, the produced coffee does not meet the quality standards of consumers. As such, this study aimed to analyse the factors that may motivate or dissuade farmers from adopting GI-based quality standards for Robusta coffee in Temanggung Regency. A descriptive method; specifically, a survey; was used for data collection. This data was then analysed using the partial least squares (PLS) method. The findings of this study revealed that, while knowledge did not motivate the adoption of GI standards, optimising collaboration between farmers and relevant associations may increase the adoption of GI-based quality standards among Robusta coffee farmers in Temanggung Regency.</jats:p

A test on pollen viability and fruits forming ability of some melon varieties by using storage treatment

Abstract Climate change decreases biodiversity through hybridization. The warming climate affects the spread of hybridization. The production of melon fruit in Indonesia fluctuated from time to time from the seeds’ lousy quality. An effort to improve melon seeds’ quality was needed using hybridization. However, the low availability of high viability pollen became one of the problems in the hybridization process. This research aimed to study the pollen’s viability and produce two varieties of melons using some storage treatments. The research used Randomized Complete Block Design with split-plot design by using two treatment factors, the main plot and storage treatment were used as the subplot. The combination of varieties and pollen storage was significant for the viability of the pollen. Golden Melon Variety A and B had different pollen viability. Using a two-day storage treatment at low temperatures, Golden Melon Variety B showed the highest pollen viability. Storage treatment took effect on the percentage of the number and the weight of the fruits produced. The 0-day storage treatment at low temperature showed the optimum yield. Pollen viability was positively correlated with fruit weight.</jats:p

Effectivity of adding some types of organic manure on red ginger (Zingiber officinale Rosc. var. rubrum)

Abstract Red ginger (Zingiber officinale Rosc. var. rubrum) is a medicinal plant that belongs to the flowering family (Zingiberaceae). Indonesian potential production of red ginger was about 22 tons Ha−1 within export volume up to 3,000 tons in 2018. This value is completely different from production yields, which decreased every year. Fertilization is one of the cultivation techniques that can increase production. This study aimed to determine the type of organic fertilizer that effectively increases the growth and yield of red ginger. The research was conducted in Jatiyoso, Karanganyar from March to August 2020 with one-factor RCBD and five treatments, it is T0 (Control), T1 (Marketed Manure), T2 (Cow Manure), T3 (Goat Manure), and T4 (Chicken Manure). Plants applied with goat manure (T3) resulted in the highest growth and yield. The growth of red ginger in terms of plant height (72.77 cm), number of tillers (14.93), and weight of fresh straw (30.89 g) tended to be higher in plants applied with goat manure. The yield of fresh rhizome weight and stored rhizome weight applied with goat manure, which is 1033.8 g and 916.8 g, was the highest value above all treatments.</jats:p

Strategy of Improving the Farmers’ Adoption to Temanggung Robusta Coffee’s Geographical Indication Standard

Abstract Temanggung Regency is a main producer of coffee in Central Java Province of Indonesia. Temanggung coffee has unique taste, as it is indicated with geographical factor. Previous studies showed the farmers’ low adoption to Temanggung Robusta Coffee’s GI standard. It made their coffee product not having added-value and incapable of competing in the market with good price. For that reason, this research aimed to formulate the strategy of improving the farmers’ adoption to Temanggung Robusta coffee’s GI standard. Data was collected through in-depth interview, observation, document study, and discussion. Thirty informants were employed in this study, coming from related office, facilitator, coffee seller, coffee maker, MPIG-KRT administrator, farmer group, consumer, and farmers. Data analysis was conducted using IFE-EFE matrix, SWOT analysis, and QSP Matrix.</jats:p

Study of Shallot (Allium ascalonicum L) Seed Viability From True Shallot Seed (TSS)

Abstract The use of shallot bulbs as the main planting material has many weaknesses, so one of the solutions is to use botanical seeds (True Shallot Seed). Physiologically, good seeds have embryos, endosperm, radicles, and testa. Seed viability demonstrated by the viability of seeds, metabolically active, and has enzymes that can catalyze metabolic reactions for germination. The purpose of this study was to determine the potential of the seed to determine its quality. One method for testing seed potential is the viability test through the tetrazolium test and the vigor test through Germination Rate. This research used local varieties of Trisula yields in 2015 (TR 1), Trisula yields of 2018 (TR 2) and as a control used Tuk-Tuk varieties. The results of the viability test using tetrazolium showed that the average viable seeds in the TR1 variety were 90.5%, TR2 94%, Tuk-tuk 95.5% which meant that the potential of the seed was still good because it was over 80%. The results of the vigor test through the measurement of germination rate gave significantly different results on each variable with an average yield of TR1 8.45% per etmal, TR2 11.41% per et mal, and Tuk-tuk 14.27% per et mal.</jats:p

Growth and yield responses of three accessions of Centella asiatica grown in lowland under varied watering intensities

Abstract C. asiatica presented the best vigor when planted at an altitude of 2500 meters above sea level. Drought is the main environmental stress in C. asiatica cultivation. The objective of this study was to determine which accession of C. asiatica that grows and produces optimally under stressed conditions since no known accession can grow optimally with various drought stresses. The study conducted in a screen house, Jumantono, Universitas Sebelas Maret Surakarta, from 4 May to 5 August 2019. The research used a completely randomized design with a variety of C.asiatica accessions (accession 1, 2 and 3) as the first factor and variety of watering intensities (once a day, once every two days, once every three days, and once every four days) as the second factor. The results showed that there was an interaction between accessions and watering intensity only on the number of tillers. Accession 1 was a drought-tolerant accession because it grew optimally in almost all variables. Watering intensity once a day was the optimum treatment for C. asiatica growth.</jats:p

Role of phosphate fertilizer on growth and yield of hybrid maize (Zea mays L.)

Abstract Maize (Zea mays L.) is a strategic commodity because its high productivity and diverse uses. This study aims to obtain a dose of phosphate fertilizer which increases growth and yield of hybrid maize. The research was conducted on the acid dry land, Faculty of Agriculture, UNS, Jumantono in June-September 2019. The research method used was an experimental method with a Randomized Completed Block Design one factor with four dose and was repeated six times. The dose is 0; 100; 150; 200 kg. ha−1 P fertilizer. The observed variables namely plant height, number of leaves, stem diameter, leaf area index, fresh stover weight, dry stover weight, weight of cobs with husks, weight of cobs without husks, average of cobs per plant, number of seeds per plant, weight of seeds per plant, weight of seeds per hectar, and weight of 100 seeds. Application of 150 kg.ha−1 of phosphate fertilizer SP-36 increases growth variable on the leaf area index (LAI). The application of 150 kg.ha−1of phosphate fertilizer SP-36 increases yield variable on the weight of 100 seeds. But seen from the average dose of 100 kg.ha−1 has a higher yield than the control because it increases yield per hectare (5.91%) to 2.15 tons.ha-1.</jats:p
