Abstract

Clove is used for spice and a raw materialof kretek cigarret industry. In the last five years (2010-2014) the price of clove was relatively higher, hence encourage farmers to improve the crops and increase productivity that are currently relatively low. Programs that can be rolled out are rejuvenation, intensification and rehabilitation in which technological innovation applied. Development funding for the program is possible if the farming isfinancially feasible. This study aimed to analyze the current projected costs, revenue and financial feasibility of clove farming with the application of innovation in line with rejuvenation, intensification and rehabilitation program to improve clove productivity and development funding for the three programs. The financial analysis method was used to analyze input and output values based on market prices. Data of inputs were obtained through a survey of farming in Bogor and Sukabumi in late 2014 and implementation of appropriate innovation for rejuvenation, intensification, and rehabilitation. Data of outputs are projected with basic data obtained from the survey with a corresponding innovation in rejuvenation, intensification, and rehabilitationapplied. The analysis showed that the program of rejuvenation, intensification, and rehabilitation generate revenue streams that were greater than the current cost and can generate sufficient excess (profit) indicated by higher value of NPV, B/C ratio and IRR. Thus the three programs were eligible to apply to external financing through micro-financing. Financing may be granted for investments and working capital, and can be full or partial.Keywords: clove (Syzigium aromaticum), rejuvenation, intensification, rehabilitation, stream of cost, stream of revenue, financial feasibility, and microfinance AbstrakCengkeh merupakan komoditas y ang digunakan untuk rempah dan bahan baku industri rokok kretek. Dalam lima tahun terakhir (2010-2014) harga cengkeh relatif baik sehingga mendorong petani untuk memperbaiki tanaman cengkeh. Hal ini merupakan kesempatan untuk meningkatkan produktivitas tanaman yang saat ini relatif masih rendah. Program yang dapat digulirkan adalah peremajaan, intensifikasi, dan rehabilitasi yang di dalamnya diterapkan inovasi teknologi. Pengembangan pembiayaan untuk program tersebut dimungkinkan jika secara finansial usahatani layak untuk dilaksanakan. Penelitian ini bertujuan untuk menganalisis proyeksi arus biaya, penerimaan dan kelayakan finansial usahatani cengkeh dengan penerapan inovasi dalam rangka peremajaan, rehabilitasi, dan intensifikasi untuk meningkatkan produktivitas cengkeh serta pengembangan skema pembiayaan untuk ketiga program tersebut. Metode yang digunakan adalah analisis finansial yaitu analisis nilai input dan output berdasarkan harga pasar. Data input diperoleh melalui survei usahatani di Bogor dan Sukabumi pada akhir tahun 2014 dan referensi penerapan inovasi intensifikasi, peremajaan, dan rehabilitasi tanaman cengkeh. Data output diproyeksikan dengan data dasar yang diperoleh dari survei dengan kenaikan sesuai inovasi yang diterapkan. Hasil analisis menunjukkan bahwa program peremajaan, rehabilitasi, dan intensifikasi menghasilkan arus penerimaan yang lebih besar daripada arus biaya sehingga dapat menghasilkan NPV, B/C rasio, dan IRR yang memadai. Dengan demikian ketiga program tersebut layak untuk pembiayaan eksternal melalui pembiayaan mikro. Pembiayaan diberikan untuk investasi maupun modal kerja, baik pembiayaan penuh maupun parsial.Kata kunci: cengkeh (Syzigium aromaticum), peremajaan, intensifikasi, rehabilitasi, arus biaya, arus penerimaan, kelayakan finansial, dan pembiayaan mikro.

Abstract

ABSTRACTHelopeltis antonii is one of the major pests in most cashew growingareas in Indonesia. The pest attacks cashew plants in the nursery and alsoin the fields which caused significant damage. Apart of cashew the insectshave a lot of alternate host plants such as tea, cocoa, neem, pepper,mangoes, jamboes, etc. This research was aimed at investigating thedispersion pattern of H. antonii in cashew plantation. The research wasconducted in smallholder cashew plantation in Ngadirejo, Wonogiri,Indonesia from March 2004 to May 2006. The observation of H. antoniipopulation was carried out on 60 sample plants which selectedsystematically in about 2 ha cashew plantation area every two weeks.Distribution analysis using various indices of dispersion and regressionmodels was applied to evaluate the dispersion of H. antonii in cashewplantation. The result shows that variance to mean ratio (s 2 / x ), χ2, Lloydmean crowding, Green’s coefficient of dispersion and Taylor’s power lawindicate aggregated distribution when the population is high duringflushing-flowering seasons of cashew plants, and it indicates regular orrandom distribution when the population is low during post-floweringseasons. The aggregated distribution on cashew plants indicated that thereis a preferency to food sources of the plants and an individual behaviour toaggregate. Therefore, sampling and monitoring H. antonii in cashewplantation should be carried out systematically during flushing-floweringseasonsKey words: Cashew,  Anacardium  occidentale,  pest  management,Helopeltis antonii, dispersion, Central JavaABSTRAKPola sebaran Helopeltis antonii Signoret (Hemiptera:Miridae) pada pertanaman jambu meteHelopeltis antonii merupakan salah satu hama utama tanamanjambu mete yang ditemukan hampir di setiap area pengembangan mete diIndonesia. Hama ini menyerang tanaman jambu mete sejak pembibitanhingga di lapangan dengan kerusakan yang cukup signifikan. Selain jambumete, serangga ini juga mempunyai banyak inang alternatif antara lain teh,kakao, mimba, lada,mangga, jambu air dll. Penelitian ini bertujuan untukmenentukan sebaran serangga tersebut, khususnya sebaran horizontal padapertanaman jambu mete. Penelitian dilakukan di pertanaman jambu metemilik petani di daerah Ngadirejo, Wonogiri, Indonesia dari Maret 2004sampai Mei 2006. Pengamatan populasi H. antonii dilakukan pada 60tanaman sampel yang dipilih secara sistematik pada area pertanamanjambu mete seluas kurang lebih 2 ha setiap 2 minggu sekali. Hasil analisismenggunakan beberapa indek pengelompokan dan model regresi yaiturasio keragaman terhadap rata-rata (s 2 / x ), χ2,rata-rata pengelompokandari Lloyd, koefisien sebaran dari Green dan hukum kekuatan Taylormenunjukkan penyebaran yang mengelompok jika populasi tinggi selamamusim pembentukan tunas dan pembungaan jambu mete, dan merata atauacak jika populasi rendah sesudah musim pembungaan. Pengelompokan H.antonii pada tanaman jambu mete menunjukkan adanya ketertarikan padaketersediaan makanan pada tanaman jambu mete dan perilaku individuserangga tersebut. Oleh karena itu untuk pengambilan sampel danpengamatan serangga tersebut sebaiknya dilakukan secara sistematis padasaat musim pembentukan tunas dan pembungaan.Kata kunci: Jambu mete, Anacardium occidentale, pengendalian hama,Helopeltis antonii, sebaran, Jawa Tengah

Abstract

The use of diesel-oil and solar energy as an alternative energyfor Virginia tobacco curingThe use of diesel oil and solar energy in the curing on Virginia tobacco was studied in two steps, i.e., the laboratory experiment al Ihe Research Institute for Tobacco and fiber Crop Malang and ield experiment (economic scale) in East Lombok, NIB. The study was conducted from July to September 1998. The laboratory experiment was aimed at evaluating the effect of diesel oil on (he aroma of cured leaves. Results showed that there was no Strange aroma of Ihe cured-leaves, as the effect of diesel-oil burning Ihe experiment using economic scale curing-bani indicated that the diesel-oil consumption was 0 76 l/kg krosok and if flat-plate solar collector was constructed as a roof, consumption decreased 7.84% which was equal with 0.06 l/kg krosok or 2.574 kJ/kg krosok. Economic analyses showed that using diesel-oil and flat-plate solar collector as a energy source gave a proit chance and an ability to pay the 18%/year of the capital interest, with B/C ratio -1.74, NPV=Rp 45 340 131, and IRR-52 93%. If only diesel-oil was used, it gave a lower proit with B/C ratio=l.77, NPV=Rp 46 425 215. and IRR=53.19%. The increase in the diesel-oil price up to Rp I 500/1 would give a profit chance and an ability lo pay the capital interest, with the B/C ratio = 1.487 and 1 .490. with IRR = 52.67% dan 52 99%, for curing the tobacco leaves with diesel-oil and solar collector, and with diesel-oil only, respectively.

Technology for canola development in Indonesia, at present is not yet available. This research activity is the first expeiment on canola conducted in Indonesia. The objectives of the expeiment was to study the vegetative and generative characters of canola plant and the oil content of the canola seeds as affected by fetilizers applications. The expeiment was conducted at Gunung Putei Expeimental Station in Cipanas, W. Java, from October 1998 to Apil 1999. The altitude of the expeimental garden is 1 500 m above sea level, the soil type is andosol, and rainfall type A according lo Schmidt and Ferguson classification. The experiment used Randomized Block Design with two factors, variety of canola and fertilizer applications. The treatments under study was conducted with plot size 60 mi and three eplications. The treatments consisted of thee levels of fetilizer application with ive vaieties of canola, Hyola 401. Hyola 330. Hyola 308. Hyola 420. and Hyola 60009. The results of the expeiment showed that the highest number of pod production deived from Hyola 308 while the lowest was produced by Hyola 401, with average 123.6 and 85.3 pods, respectively. Number of seeds per pod vaies between vaieties range from 20.0 to 25.1. Whee the lowest was produced by Hyola 401 while the highest by Hyola 60009. Seed weight per 1000 seeds vanes between vaieties, with average 4.0-5.5 grams. The combination of fetilizer application and vaiety of canola affected the oil content of seed produced, ranged between 41.68 and 46 97%. Based on the performance of vegetative and generative growth and oil content of seed produced, it can be concluded that the canola plant is promising to develop in Indonesia.

Abstract

Sugarcane is an important commodity in Gorontalo Province. However, the development of sugarcane farming is constrained by limited cultivation land and low productivity of sugarcane. The government continues to improve farm productivity and efficiency through the application of technology, optimization of the use of agricultural tools and machinery, production input assistance, improvement of irrigation networks, and other supporting facilities. Increasing farm efficiency is vital to increase farmers' production and income. This study aimed to determine the technical capability, allocative, and economical of sugarcane farming, and find out the factors that influence the efficiency of sugarcane farming in Gorontalo. The study was conducted in 2017 with a survey method with questionnaires or a structured questionnaire. The research location was determined purposively in one of the sugar cane production centers of Gorontalo Province, namely Boalemo Regency. The selection of respondents was carried out by a simple random sampling technique with a total of 47 sugarcane farmers. The data analysis method uses the Cobb Douglas stochastic frontier production function with the Maximum Likelihood Estimates. Financial analysis of farming was done to determine the feasibility of sugarcane farming. The results showed that the average level of technical, allocative, and economic efficiency of sugarcane farming in Gorontalo were 0.90, 0.52, and 0.53, which means that sugarcane farming was technically efficient, but not yet allocatively and economically efficient. Six out of seven variables that influence the inefficiency of sugarcane farming were farmers' education, farming experience, frequency of counseling, participation in farmer groups, credit access, and technological assistance. The age variable does not significantly affect the technical inefficiency of sugarcane farming.Keywords  : Maximum Likelihood Estimates, sugarcane national production.

Abstract

Status of cadmium and rhizome yield l/temuireng (Cur¬ cuma aeruginosa Roxb.) at by d fferent dosages phos¬ phatefertilizerCadmium is a heavy metal which is for human being. The concentration of Cd in the soil will increase if phosphate fertilizer is applied, because Cd is available in the sediment rock of phosphate as a raw material for phosphate fertilizer. Recently it is said that simplicia of medicinal crops originated from Asia is contaminated with heavy metals. That contamination mainly derives from Ihe environmental growth. Theefore, the research on the status of Cd in rhizomes Curcuma aeruginosa Roxb. due phosphate fertilizer is essential to be conducted. The experiment was conducted in the experimental garden of Research Institute for Spice and Medicinal Crops from August 1997 - June 1998. The experiment used polybags which were illed with 25 kg Bogor dry latosol soil mixed with I kg of rice husk and 2 kg cattle manue It used randomized block design (RBD) with four replications and ive samples each treatment. The treatments were (I) no NPK; and 8 dosages of TSP, (2)0; (3)2.5; (4)5; (5)7.5; (6)10.0; (7)12.5; (8)15.0; and (9)20.0g/ polybag respectively. Each TSP treatments was added with 1 5 g uea and 19 g KCI/ polybag. The plant wee harvested at 8.5 month after planting. The results of experiments showed that application of2.5; 5; 7.5; 10; 12.5; 15; and 20 g/polybag of TSP increased dry weight of simplicia from 24.3- 40%. The content of Cd in rhizomes, produced by plant with 5 up to 20 g TSP fertilizer was 1.181 - 2.756 ppm. The Cd content was higher than tolerance limited value as determined by laws of heavy metal in Japan (I ppm) and WHO (0.24 ppm). While fertilizer teatments of 0 and 2.5 g TSP produced rhizomes with Cd content 0.630 - 0.945 ppm, and it is still under tolerance limited value by Japan, but, higher than WHO laws. Due to high Cd content in rhizomes (1.181 - 2.756 ppm), those simplicia can not be used as row material for medicine.

Abstract

The physical and chemical properties of the growing medium for root trainer of rubber are critical to support plant growth. This study aimed to obtain the best medium for growing rootstock rubber seedlings in the root trainer.  Rubber clone PR 300 seeds were germinated for 21 days, then raised in root trainer pots for five months. The treatments evaluated were a mixture of cocopeat, Rawapening peat, and manure at different ratios.  The experiment was designed in a Randomized Block Design, three replications, 30 plants per replicate, totaling 720 plants. The observed variables were N, P, K, Mg, C-organic content, pH, and cation exchange capacity of cocopeat, peat, and manure, as well as plant growth (height, stem diameter, wet weight, and dry weight). ANOVA used for analyzing data, followed with the Duncan Multiple Range Test at 5% level. The results showed that there were three best root trainer media for PR 300 rubber rootstock seedlings were a mixture of cocopeat + peat (1:1), cocopeat + peat + manure (1:2:1), and cocopeat + peat + manure (2:1:1). The growth and compactness of the roots are outstanding, so the seedlings are easily removed from the root trainer pots without significant damage. Based on the initiation and cost, the best root trainer medium is a mixture of cocopeat + peat + manure (1: 2:1). It is necessary to study the use of other types of peat soils apart from Rawapening. Also, it needs to be observed further plant growth after inoculation with the stem and after planting in the field.Keywords : Planting medium, Rawapening peat, rubber clone PR 300.
