Abstract

   The purpose of the research is to analyze the feasibility of watermelon farming in Wonosari Village, Ngombol District, Purworejo Regency and find out the factors that influence the success of watermelon farming. It was assumed that the farmers, land, capital, labor, technology, extension facilities, production and prices affected the success of watermelon farming in Wonosari Village. The method of determining the research area was carried out purposively while the sampling method used simple random sampling with 33 watermelon farmers as respondents. The feasibility analysis using the t test and multiple linear regression analysis.The revenue of each farm (0,42 ha) is Rp. 11,360,606.06 and the average total cost is about Rp. 4854,422.81 per 0.42 ha. The average income of watermelon farming is about Rp. 11,506,183.25 per 0.42 ha. Watermelon farming is feasible to be cultivated with the result of R / C Ratio is 3.37. The factors that influence the success of watermelon farming with multiple linear regression using T-test show that the variables of farmer (x1) and land area (x2) has no significant effect on success. While variables of capital (x3), labor (x4), technology (x5), extension facilities (x6), price (x7), and production (x8) have a significant effect on the success of watermelon farming. The F-count test from the test results obtained a value of sig 0,000 smaller than 0.05 and F-count is 18.584 greater than F-table 2.034 which means Ha is accepted, also means there is an influence of variables simultaneously on y.

Abstract

Karies gigi yang mencapai pulpa dapat menyebabkan nekrosis pulpa. Bakteri yang dapat menyebabkan nekrosis pulpa, salah satunya Staphylococcus aureus. Perawatan terhadap nekrosis pulpa adalah dengan melakukan perawatan saluran akar (PSA). Salah satu tahapan dalam PSA adalah sterilisasi saluran akar dengan menggunakan kalsium hidroksida (calcium hydroxide) atau kresotin (cresotin). Penggunaan obat kimia, utamanya dalam jangka panjang, dapat menimbulkan efek samping, sehingga diperlukan bahan alternatif lain yang lebih aman dan alami, seperti penggunaan jintan hitam (Nigella sativa). Zat aktif yang terkandung dalam jinten hitam dapat bersifat sebagai antibakteri diantaranya adalah tannin, terpenoid, saponins, alkaloids. Penelitian ini bertujuan untuk mengetahui efektifitas ekstrak jinten hitam dalam menghambat pertumbuhan bakteri Staphylococcus aureus secara invitro dengan metode difusi agar.  Penelitian ini menggunakan  ekstrak biji jintan hitam (Nigella sativa) dengan konsentrasi 50%, 75% dan 100%. Rancangan penelitian yang digunakan adalah penelitian Post Test Only Control Group Design, yang terdiri dari lima kelompok yakni, kelompok kontrol negatif (aquadest steril), kelompok perlakuan 1 (ekstrak jintan hitam konsentrasi 50%), kelompok perlakuan 2 (ekstrak jintan hitam konsentrasi 75%), kelompok perlakuan 3 (ekstrak jintan hitam konsentrasi 100%) dan kelompok kontrol positif (cresotin). Sampel yang digunakan dalam penelitian ini adalah bakteri Staphylococcus aureus ATCC 25923, dan besar sampel yakni pengulangan sebanyak lima kali untuk setiap kelompok. Hasil uji statistik dengan man witney U terdapat perbedaan yang signifikan antar kelompok dalam menghambat pertumbuhan bakteri Staphylococcus aureus secara in vitro. Simpulan deari penelitian ini bahwa ekstrak jintan hitam (Nigella sativa) dengan konsentrasi 50%, 75% dan 100% dapat menghambat pertumbuhan bakteri Staphylococcus aureus secara in vitro.

AbstractThis study aims to determine the optimum potential and optimum time of elektrocoagulationprocess, with aluminum and graphite electrodes to reduce hypochlorite ions form the water pool anddetermine the concentration of hypochlorite ions before and after electrocoagulation process. Thesubject of this research was optimum electric potential and optimum time of electrocoagulationefficiency against hypochlorite reduction. The Object of this research was hypochlorite ions in poolwater Hercules Maguwoharjo Yogyakarta. The Optimization of the electrical voltage was done onvariation 4, 6, 8, 10, and 12 volts and optimization of the time electrocoagulation process was doneon variations 2, 4, 6, and 8 hours. Parameters used are concentration of hypochlorite ions in thewater. The Effectiveness of electrocoagulation was seen from the graph of changes in theconcentration of hypochlorite ions after electrocoagulation process. The determination ofhypochlorite content was using uv-vis spectrophotometry with wavelength 556 nm. The resultsshowed that the highest electric potential is 12 volt and the longest time of electrocoagulation processis 8 hours. The Use of electrocoagulation method for pool water treatment effectively decreases theconsentration of hypochlorite ions.Keywords : elektrocoagulation, hypochlorite, aluminum, graphite.

Abstract

Essential oil is the oil obtained from distilling red lemongrass. This research was conducted in Terong, Dlingo, Bantul at the Red Lemongrass Farmers Association. The purpose of using soil conditioners is to increase citronella content and yield of red lemongrass essential oil. The soil improver used is manure, while other fertilizers are kasgot, POC, mycorrhiza, and PGPR. Treatment using CRD with the composition of base fertilizer + kasgot + mycorrhiza, base fertilizer + kasgot + POC, and base fertilizer + kasgot + PGPR. The treatment was repeated 3 x so as to get 27 samples and 1 control using urea. From the test results in the CEOS laboratory using CGMS, it was found that using the basic fertilizer + kasgot + PGPR treatment obtained maximum results in all types of lemongrass plants (Lenabatu, Mahakemiri, and Aster types). However, when viewed with the income received, it turns out that the Lenabatu type has the highest income compared to the others. This may be the type of Lenabatu that is suitable for planting in the area, thus supporting the treatment. The highest increase in income on Lenabatu because it is influenced by the increase in yield and citronella levels. So that with an increase in yield and citronella levels can increase the selling price which has an impact on the increase in income earned due to the price received is different from the price below the market price (the market price is determined by the yield or citronella content). The citronella content in the market is about 40% while the yield is 1 lt/3 kw. By using the treatment, the citronella content and yield change, especially in Lenabatu which gets high citronella content and yield, resulting in high prices. Keywords: Citronella, GC-MS, Soil Improvement, Essential Oil INTISARIMinyak atsiri adalah minyak yang diperoleh dari hasil penyulingan Sereh Merah/Sereh Wangi. Penelitian ini dilakukan di Terong, Dlingo, Bantul pada Paguyuban Petani Sereh Merah. Tujuan dari penggunaan faktor pembenah tanah adalah meningkatkan kadar citronella dan randemen dari minyak atsiri Sereh Merah. Pembenah tanah yang dipergunakan adalah pupuk kandang, sedangkan pupuk yang lain adalah kasgot, POC, mikoriza, dan PGPR. Perlakuan dengan menggunakan CRD dengan komposisi pupuk dasar+ kasgot+ mikoriza, pupuk dasar + kasgot + POC, dan pupuk dasar + kasgot + PGPR. Perlakuan tersebut diulang sebanyak 3 x sehingga mendapatkan 27 sampel dan 1 kontrol menggunakan urea. Dari hasil uji di laboratorium kandungan minyak atsiri dengan menggunakan GCMS, diperoleh bahwa dengan menggunakan perlakuan pupuk dasar + kasgot + PGPR memperoleh hasil yang maksimal pada semua jenis tanaman sereh wangi (Jenis Lenabatu, Mahakemiri, dan Aster). Akan tetapi jika ditilik dengan pendapatan yang diterima ternyata jenis varietas Lenabatu yang memperoleh pendapatan tertinggi dibandingkan dengan lainnya. Hal ini dimungkinkan jenis Lenabatu yang cocok ditanam di daerah tersebut, sehingga mendukung hasil yang positif terhadap perlakuan. Peningkatan pendapatan terbanyak pada Lenabatu karena dipengaruhi adanya kenaikan rendemen dan kadar citronellanya. Sehingga dengan adanya kenaikan randemen dan kadar citronella bisa menaikan harga jual yang berimbas pada kenaikan pendapatan yang diperoleh akibat harga yang diterima berbeda dengan harga yang dibawah harga pasar (harga pasar ditentukan oleh randemen atau kadar citronellanya). Kadar citronella di pasaran sekitar 40% sedangkan rendemennya 1 lt / 3 kw. Dengan menggunakan perlakuan, maka kadar citronella dan randemen berubah, terutama pada Lenabatu yang mendapatkan kadar citronella dan randemennya tinggi, sehingga berimbas pada harga tinggi Kata kunci: Citronella, GCMS, Pembenah Tanah, dan Minyak Atsiri
