Abstract

Kulon Progo is the area with the largest cultivation area for cocoa commodity in Special Region of Yogyakarta, which is 3,522 Ha [Goverment Database Statistics, 2013]. This study was conducted to analyze the performance of the value chain of cocoa beans. The data used in this study was the primary data obtained depth interviews with respondents from; farmers, farmer groups, cooperatives, companies and consumers. The method used to analyze in this study was the economic value added method. From the result, the highest revenue was found in the sales of the fermented dry cocoa seeds which was about 15.47; this showed that it is necessary for the farmers to apply the fermentation process to their cocoa products in order to boost their value and get bigger revenue. But the problem was the farmers need more time for the fermentation process as well as spending more money in buying fermentation box which are needed for the fermentation process. The sales of wet or non-fermented dry cacao seeds actually have low R/C value but farmers just do not want to bother themselves with the fermentation process so they end up in selling their products in wet or non-fermented dry state. Meanwhile, the process of making chocolate bar product has not given much value yet; eventhough this process should be able to give more value, considering the price for every kg of chocolate bar is around 65,000 Rupiahs. In this case, the cost for the cacao processing machine became the depression burden which cannot be covered by the amount of the cacao products produced by farmers. The solution for this problem can be done by conducting a collective purchase through Koperasi level; by doing this the farmers can enlarge their production scale which will end up in increasing their products' R/C value

Abstract

Soybean is one of the food commodities, which contains vegetable protein, carbohydrates and fat, hence it is necessary to complement the nutrition. Demand consumption of soybean higher with increasing population annually, the production of soybean is still sufficient to complete the increasing of demand. Therefore, the increasing of soybean production has to be considered to decrease the dependency on imported. Soybean production can be increased by the cultivation technique. In this method, the present of weed should be concerned. Weed can reduce the quality and quantity of soybean. The research was done at Kebun Pendidikan, Penelitian dan Pengembangan Pertanian (KP4) Gadjah Mada University which located at Kalitirto, Berbah, Sleman, Yogyakarta, Indonesia. This research started on November 2015-April 2016. The research aims to identify the effects of weed on the growth analysis of several soybean cultivar. This field research is arranged using spit plot with three blocks as the repetition where the main-plot is the weed treatments andthose are weed-free, weeding in a critical period, and weedy. Sub plot is the soybean cultivars which are Anjasmoro, Argomulyo, Burangrang, Gema, Gepak Kuning, Kaba, and Wilis. The research’s result show the weed treatments would effect no significant difference in the leaf area index, net assimilation rate, crop growth rate (3 to 6 weeks after planted/WAP), specific leaf weight, and leaf area ratio (3 WAP). Which affects are the crop growth rate (6 to 9 WAP) and leaf area ratio (6 and 9 WAP)

Abstract

The conversion of forest for another purpose has made the population and diversity of medicinal plants increasingly threatened. The ex situ conversion by cultivation is needed to provide the suitable environment to ensure the plants grow in their natural habitat and maintain their properties. One of the traditional medicinal plants in Sanggau Malay which has been believed to neutralize the toxin is “anggrek penawar racun” (Plocoglottis lowii Rcbb.f.). This research was important to be done since there was no data and information about mychorrizal type associated to root of orchid P. lowii Rchb.f. in its natural habitat. The aim of this research was to find out the data and information about the types, the characteristics, and the percentage of mycchorizal fungal infection in root tissue for conservation and cultivation purpose. The research used 10% KOH heating method and freehand section coloring using Trypan Blue, Acid Fushin dan Safranin-O conducted in cross section of the roots. The results showed that there was only one species of fungi and it was identified as Rhizoctonia sp. Binucleate type. The highest percentage of mycchorizal infection  occurred at the tip of the roots (90%). It has been found that the location of mychorrizal infection has occurred between the epidermis and cortex. It is needed to do the further study about mychorrizal isolate Rhizoctonia sp. effectiveness in the growth of P. lowii Rchb.f in the cultivated land.

Abstract

This research aim to determine the effect of fermented goat's biourin dose on growth and yield of beans. The research was conducted in Krapyakrejo Village, Gadingrejo District, Pasuruan at an altitude of 5 m above sea level in March - May 2018.The research used a randomized block design and repeated five times, the treatment was a fermented goat’s biourin dose consisting of five levels: P0 (Control) : ZA 300 kg/ha, SP36 200 kg/ha, KCl 100 kg/ha; P1: POC 1.500 l /ha + ZA 300 kg /ha, SP36 200 kg/ ha, KCl 100 kg/ha; P2: POC 2.000 l ha + ZA 300 kg/ha, SP36 200 kg/ha, KCl 100 kg/ha; P3: POC 1.500 l/ha + ZA 150 kg/ha, SP36 100 kg/ha, KCl 50 kg/ha and P4: POC 2.000 l/ ha + ZA 150 kg/ha, SP36 100 kg/ha, KCl 50 kg/ha.The results showed that beans with higher yields were found in POC 2.000 l/ha and inorganic half-dose treatment which produced 26,01 tons/ha, POC 2.000 l ha and full-dose inorganic produced 24,53 tons/ha, POC 1.500 l/ha and full-dose inorganic produced 24,29 ton/ha, POC 1.500 l/ha and inorganic half dose produced 23,56 ton/ha and controls give lower yields, 22,94 tons/ha.

Abstract

Strawberry (Flagaria chiloensis, L.) is a herbaceous plant thatpropagates, the fruit contains lots of fiber, vitamin C, folic acid, potassium and antioxidant. The research was conducted in the experimental field of the Agriculture Faculty, Gajah Putih University, Blang Bebangka, Pagasing District, Central Aceh Regency with a height of ± 1,150 m above sea level, soilpH 5.5 – 6.0. This research was conducted in February until April 2018. The research used factorial randomized block design (RBD) with two factors. The first factor is organic mulch consisting of 4 levels, (M0) = No mulch (control); (M1) = wood sawdust mulch; (M2) = rice husk mulch; (M3) = waste coffee mulch. The second factor is the ratio of planting media (kg) which consists of 4levels,(T1) = soil, sand, manure (7: 1: 2); (T2) = soil, sand, manure (6: 1: 3); (T3) = soil, sand, manure (4: 2: 4); (T4) = soil, sand, manure (3: 2: 5).The results of this study indicate that wood sawdust mulch produces the average number of tillers (6.25 children) and the best strawberry fruit weight (65.66 g per clump) from organic mulch treatment. Comparison of planting media, soil, sand and manure (3: 2: 5) produces the number of tillers (7.5 tillers) and strawberry fruit weight (76.73 g per clump) which is the best from the comparison treatment of planting media. The combination treatment of comparison of planting media, soil, sand and manure (3: 2: 5) with organic mulch treatment produces the best average number of tillers and strawberry fruit weight from the treatment combination.
