White temu is one of plants which is included in pharmaceutical commodities and has potentially prospect to be developed in Leragere. So far, white temu has not been managed intensively because there is lack of knowledge about the importance of white temu to explore to be pharmaceutical product. In fact, white temu will give an opportunity to increase people income, especially if white temu is formed as instant drink white temu. This research is aimed to study cost, revenue, profit and efficiency of white temu producing in Leragere area. Location is purposively determined as Leragere is considered as white temu area development. The samples are decided as many as 25 people, in line with quota systematic sampling with reason of population homogeneously characteristic. Collected data is included primary and secondary data, which is managed by using farming analysis tool in line with research goal and it is interpreted as equal as analysis result

In Indonesia, orchid is one of advanted crop. Crop multiplication of orchids usually produce with seed culture. Each embryo from seed culture can be multiplied by mericlone. The objective of this research is determine the type of media benzyl adenine concentration for growing and embryo’s proliferation of Phaleaenopsis amabilis. The research used complete randomized design factorial consist of 2 factors with 3 replications. First factor is type of media consist of 3 levels which are ½ Murashige and Skoog (½ MS), Vacin and Went (VW), New Phalaenopsis (NP). Second factor is Benzyl adenine concentration consist of 4 levels which are 0 ppm, 0.5 ppm, 1 ppm and 1.5 ppm. Each bottle are inoculated by 5 embryos/PLB of white Phalaenopsis amabilis. Data had been analyzed with F test in 5% level. The highest number of embryos per explants are shown from combination between ½ MS media with 0.5ppm BA. The results showed that highest number of leaves and roots per explants are from NP media. Media without benzyl adenine produced the highest number of leaves and roots. The highest number of diameter is produced by VW media which combine with 1.5 ppm benzyl adenine

The study aimed to determine fowering and production performance of milk stage corn planted in critical sandy land with bio mulch. Plastic mulch and bio mulch (feedstuff used), were used on 3 (three) beds planted with Pioneer® seed corn. Seeds were planted with 25 x 50 cm in sandy land Jangkaran Village, Temon, Kulon Progo, Yogyakarta. Litter manure waste was used as basal fertilizer by spreaded over the beds at the level 7.5 t/ha. Corn seed planted on the bed without basal fertilizer and mulch as a control. Chemical fertilizers, urea and SP-36 are given in equal amounts and the corresponding frequency written on the label. Water was given to corn plant every other day. Quantity of flower was observed since the first time produce flower up to harvested at 10 weeks, while production was determined from total weight of whole plant harvested. The study is based on completely randomized design (CRD) and the data were analyzed by ANOVA with SPSS advanced analysis of LSD. Corn plant with bio mulch produced significantly higher of flower and whole plant compare with control but not significantly higher compare with plastic mulch. However, bio mulch always has highest level of flower 34.4% compare with plastic mulch 17.7% and control 9.2; highest production level of fresh whole plant13.3, plastic mulch 12.93 and 3.91 t/ha. Utilization of mulch has significant effect on the quantity of flower and production level

The use of pesticides is widely used in the production of citrus fruits for protection before and after harvest. The use of pesticides on a broad scale can pollute the environment and leave residues in plants and in plants such as fruit leaves and tubers. A survey was conducted to evaluate the level of pesticide residues in citrus fruits. The survey method is carried out by recording pesticide use by farmers and traders. The survey will be conducted in Dau, Batu and Poncokusumo Districts, Malang Regency by interviewing 10 farmers and 10 orange traders in each District. The Gas Cromatography method was carried out to measure the levels of pesticide residues tested at the Angler Biochemlab Laboratory, Surabaya. Descriptive analysis was used to analyze the levels of pesticide residues in citrus fruits then compared to the Maximum Residue Limit (BMR) through SNI 7313: 2008 quality standards on agricultural products. The residue levels of profenofos in farmer samples were found to be higher at 0.108 ppm compared to the sample from traders, namely 0.050 ppm at the Tegalweru village research site. In addition, traders in the village of Poncokusumo knew the imidaclroripid content was close to the maximum threshold of 0.040 ppm in farmer samples and 0.010 ppm in the merchant sample. Decreased levels of pesticide residues on food can be done with several approaches, namely physically and chemically. Reduction of pesticide residues in agricultural products can be done in several ways including by washing products with running water for several times or can also be done by soaking in water for one hour

Publisher : Universitas Tribhuwana Tunggadewi

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan pupuk organik berbahan urine sapi terhadap kualitas kimia tanah di lereng Merapi, Desa Jrakah Kecamatan Selo Kabupaten Boyolali. Rancangan yang digunakan dalam penelitian ini adalah faktorial seri 2x4 pola searah, dengan ulangan sebanyak tiga kali. Faktor pertama adalah 2 jenis tanah dengan tanaman berbeda (R1 = rumput Raja dan R2 = rumput Gajah). Faktor kedua adalah 4 level dosis penggunaan pupuk organik (D0 = tanpa pemberian pupuk organik; D1 = pemberian pupuk organik sebesar 5 ton/ha; D2 = pemberian pupuk organik sebesar 10 ton/ha dan D3 = pemberian pupuk organik sebesar 15 ton/ha). Hasil penelitian menunjukkan bahwa penggunaan pupuk organik berbahan urine sapi menunjukkan pengaruh yang tidak nyata (P>0,05) terhadap pH, C-organik dan kandungan Nitrogen (N) total dalam tanah. Sedangkan penggunaan pupuk organik berbahan urine sapi menunjukkan berbeda nyata (P
