Abstract

Pengujian kadar air benih secara umum telah diatur oleh International Seed Testing Association untukberbagai keperluan, namun beberapa komoditi belum diatur secara jelas termasuk benih saga pohon. Oleh karenaitu pengembangan uji kadar air pada benih saga pohon dirasa perlu untuk dilakukan. Penelitian ini bertujuan untukmengembangkan uji kadar air benih saga pohon dengan dua metode oven yaitu suhu rendah dan tinggi. Penelitiandilaksanan di Lab. Agroekoteknologi, Universitas Trilogi sejak September-Desember 2016. Penelitian terdiri atasdua percobaan yaitu dengan metode oven suhu rendah (103±2)oC dan suhu tinggi (133±2)oC yang keduanyamenggunakan Rancangan Acak Kelompok dua faktor yaitu perlakuan benih saat di oven dan lamanya pengovenan.Untuk metode oven suhu rendah, faktor perlakuan benih saat di oven terdiri atas tiga taraf yaitu benih utuh, benihdibelah dua, benih dihaluskan dan lamanya pengovenan terdiri atas empat taraf yaitu 17 jam, 19 jam, 21 jam, dan23 jam. Untuk metode oven suhu tinggi, faktor perlakuan benih saat dioven terdiri atas tiga taraf yaitu benih utuh,benih dibelah dua, benih dihaluskan dan faktor lamanya pengovenan terdiri atas lima taraf yaitu 1 jam, 2 jam, 3jam, 4 jam, dan 5 jam. Hasil percobaan menunjukkan bahwa kadar air benih saga pohon dapat dilakukan denganmetode oven suhu rendah selama 17 jam dengan perlakuan benih dibelah dua atau selama 19-23 jam denganperlakuan benih utuh. Pengujian kadar air dengan metode suhu tinggi untuk perlakuan lamanya pengovenan dapatdilakukan selama 1 jam dan untuk perlakuan benih saat di oven dapat dilakukan dalam keadaan benih utuh.Kata kunci: benih utuh, benih dibelah dua, benih dihaluskan, lamanya pengovenan.ABSTRACTInternational Seed Testing Association generally rules the testing method of seed moisture content forvarious purposes. However, some commodities have not been clearly regulated including saga seeds. Therefore,the development of seed moisture content testing for saga seeds is considered necessary. The objective of the studywas to develop seed moisture content testing using two oven methods, namely low and high constant temperature.It was conducted at Integrated Lab. of Agroecotechnology, Department of Agroecotecnology, Trilogi Universitystarting from September to December 2016. Two experiments which were low constant temperature oven method(103±2) oC and high constant temperature oven method (133±2) oC were tested using two factors randomizedgroup design. The factors were seed treatment in the oven and period of seed drying. Low constant temperaturemethod used 3 levels of seed treatment (whole seed, half seed, and ground seed, respectively) and 4 levels of dryingperiod (17, 19, 21, and 23 hours, respectively). While high constant temperature method used 3 levels of seedtreatment (whole seed, half seed, and ground seed, respectively) and 5 levels of drying period (1, 2, 3, 4, and 5hours, respectively). The results showed that saga moisture content could be determined using low temperaturemethod with 17-hour drying period for half seeds or 19-23 hours of drying period for whole seeds. As for hightemperature method, seed moisture content testing could be done when seeds were dried for 1 hour, while for seedtreatment in the oven conducted for whole seeds.Key words: whole seed, half seed, ground seed, period of seed drying.

Abstract

Penyakit moler yang disebabkan oleh Fusarium oxysporum f.sp.cepae merupakan penyakit utama bawangmerah yang selalu ditemukan di setiap daerah penanaman dengan intensitas penyakit yang bervariasi. Variasi inididuga berkaitan dengan variasi virulensi patogennya dan variasi ketahanan varietas bawang merah. Beberapaisolat patogen diuji pada beberapa varietas bawang merah untuk mengetahui variasi virulensinya dan ketahananbawang merah terhadap penyakit moler. Lima varietas bawang merah yaitu Tiron, Filip, Kuning, Thailan, danBiru diinokulasi dengan empat isolat patogen yang berasal dari Kulonprogo (isolat Kp), Bantul (isolat Bt),Brebes (isolat Br), dan Nganjuk (isolat Ng). Sebelum inokulasi dengan cara perendaman umbi bibit dalamsuspensi mikrokonidium patogen konsentrasi 106, umbi didisinfeksi dengan perendaman dalam kloroks 1%selama 1 menit, dicuci dengan akuades steril, dan dikeringanginkan semalam. Umbi yang sudah diinokulasikemudian ditanam dalam polibeg yang berisi medium tanam yang berupa campuran tanah:pupuk kandang sapi2:1 v/v. Isolat Bt menunjukkan virulensi yang lebih tinggi dibandingkan dengan 4 isolat yang lain pada semuavarietas bawang merah yang diuji. Isolat Bt menyebabkan penyakit dengan intensitas yang lebih tinggi, danmenyebabkan kematian total pada varietas Kuning. Varietas Filip dan Biru adalah varietas yang paling tahan,sebaliknya varietas Kuning adalah yang paling rentan terhadap penyakit moler.Kata kunci: variasi virulensi, Fusarium oxysporum f.sp.cepae, resistensi, bawang merah ABSTRACTMoler (shallot twisting disease) caused by Fusarium oxysporum f.sp.cepae is a major disease on shallotthat is always found in every shallot plantation with various disease intensity. The variation of disease intensitymay be related to variation of virulence of the pathogen and the resistance of shallot varieties. Several isolatesof the pathogen were tested on several shallot varieties to know the variation of their virulence as well as theresistance of the shallot varieties. Five varieties of shallot i.e. Tiron, Filip, Kuning, Thailan, and Biru wereinoculated with four isolates of the pathogen originated from Kulonprogo (Kp isolate), Bantul (Bt isolate),Brebes (Br isolate), and Nganjuk (Ng isolate). Before inoculation by deeping the bulbs in 106/ml microkonidiumsuspension for 30 minutes, the bulbs were disinfected with 1% NaOCl for about 1 minute, washed with sterilizedaquadest, and air dryed overnight. The inoculated bulbs were then planted in polybags containing plantingmedium of soil:organic fertilizer 2:1 v/v. Bt isolate showed the higher virulence compared to 4 other isolates onall varieties tested. The isolate gave the higher disease intensity, and it caused total plant death on Kuningvariety. Filip and Biru varieties were the most resistant, whilst Kuning variety was the most susceptible to thedisease.Key word: variation of virulence, Fusarium oxysporum f. sp. cepae, resistance, shallot

Hasil penelitian menunjukkan bahwa teknik budidaya yangditerapkan oleh petani beragam sehingga produktivitasnya beragam dengan rentang 19 – 75 ton ha-1. Petanimemilih klon-klon yang telah terbukti berproduksi tinggi di daerahnya maupun di daerah lain. Produktivitasingkong yang tinggi disebabkan oleh penggunaan bibit unggul produksi tinggi, pengolahan lahan sempurna danpemupukan kandang yang dicampur pada saat pengolahan lahan. Fleksibilitas pemanenan ubi dapatdimanfaatkan oleh petani untuk mengatasi deteriorasi fisiologis pasca panen. Penelitian lebih lanjut perludifokuskan tentang keseuaian klon dan teknik budidaya yang meliputi pemupukan anorganik dan hayati denganmikroba pemacu pertumbuhan tanaman, serta kualitas singkong untuk bahan pangan dan bioethanol.Kata kunci: singkong, petani, produktivitas, teknik budidayaABSTRACTCassava can be the most efficient crop for food and altervative energy as compared with sugarcane andcorn, currently main feeding sources of world bioethanol. A survey was conducted to gather informationregarding cultural techniques used for growing cassava, with regard to clone/genetic selection, soil tillage,planting pattern and fertilization applied by farmers in Bengkulu City, and their related root productivity. Plotsof cassava crops reaching their maturity were identified. Discussions were accomplished farmers regarding withcultural techniques in growing cassava, follwed by measuring plant growth and taking samples for assessingroot growth and yield. The results demonstrated that farmers varied in applying cultural techniques for growingcassava hence their cassava yields varied greatly from 19 to 75 ton ha-1. Farmers selected cassava propagulesbased on information, both from their own vicinity or from other places, that they are high yielding. High rootproductivity was related to the use of high-yielding varieties, full tillage combined with manure fertilization. Theadvantage of flexibility in harvesting root were employed by farmers with daily harvesting to aleviate postharvestphysiological deterioration in selling fresh root. Based on this informastion, further researches shouldbe focused on the suitability of cassava clones with specific environment, cultural techniques, includinganorganic fertilization, the use of plant growth promoting rhizobacteri and their related root qualities for foodand bioethanol.Key words: cassava, farmers, cultural techniques, yield

Abstract

Mangga Gedong Gincu mempunyai prospek baik untuk dikembangkan karena mempunyai karakteristik yangsesuai dengan permintaan pasar, yaitu mempunyai kulit mangga berwarna merah, komponen serat pada daging buahcukup banyak dan mempunyai aroma sangat tajam. Penelitian ini dilaksanakan tahun 2006 di Kabupaten Cirebon,sebagai sentra produksi mangga di Jawa Barat. Tujuan penelitian, yaitu: (i) menggambarkan rantai tataniaga mangga(ii) mempelajari karakteristik pelaku lembaga pemasaran dan (iii) menganalisis margin tataniaga. Penelitianmenggunakan metoda survai. Dimana data primer dikumpulkan dari 50 petani yang diambil secara acak (RandomSampling) dan pelaku lembaga pemasaran dengan metode snowball sampling. Data sekunder diperoleh dari DinasPertanian, Badan Pusat Statistik dan Lembaga Penelitian. Hasil penelitian menginformasikan, bahwa buah GedongGincu dipasarkan dalam bentuk grade A/B dan grade C (non grade). Pemasaran grade A/B melalui dua saluran,yaitu, pertama: petani – pengumpul - pedagang besar – agen - toko/kios buah – konsumen dan kedua: petani –pengumpul – pedagang besar – agen – suplayer – supermarket – konsumen sedangkan grade C melalui satu saluran,yaitu saluran ketiga: petani – pengumpul – pedagang besar – pedagang pasar tradisional – konsumen. Marjinpemasaran saluran pertama Rp.10.920,-/kg, berasal dari pedagang besar (48,1%), toko/kios (35,4%), agen (14,2%)dan pengumpul (2,3%). Marjin pemasaran saluran kedua Rp.15.000,-/kg, berasal dari pedagang besar (34,9%),suplayer (26,6%), supermarket (26,6%), agen (10,2%) dan pengumpul (1,7%). Keuntungan pedagang besar lebihtinggi dibandingkan agen, yaitu masing-masing Rp.3.350,-/kg dan Rp.1.460,-/kg. Permasalahan pemasaran manggaGedong Gincu yaitu posisi petani seringkali lemah dalam penentuan harga jual, jumlah serta mutu produk yangdihasilkan tidak selalu sesuai permintaan pasar, petani bermodal lemah sering terperangkap ke pelepas uang (moneylender) dan ditemukan pungutan-pungutan liar dalam kegiatan transportasi pengiriman mangga ke agen di pasar-pasarinduk. Dalam hal ini, perlu peningkatan aksesibilitas petani terhadap informasi pasar termasuk permintaan, variasi hargamusiman dan trend harga dengan demikian mereka dapat menyesuaikan rencana penjualan mangga untuk mencapaipenjualan efisien dan menguntungkan.Kata kunci: mangga, analisis pemasaran, Jawa Barat ABSTRACTGedong Gincu have a good prospect to be developed because it has some characteristics as good as marketrequest, namely mango’s skin is red, mango contains a lot of fiber components and aroma of ripe mango is verysharply This study was conducted in 2006 and took place in Cirebon District, as centre of mango production of WestJava. The objectives of study were; (i) to describe the marketing channel, (ii) to learn the characteristics ofmarketing institution and (iii) to analyze marketing margin of mango. This research used method of survey applyingstructured questionnaires. Primary data were collected from 50 farmers selected by random sampling and somemarketing institutions using snowball method. Secondary data were collected from the Agriculture Office, the CentreAgency of Statistic and the Research Institutions. Results showed, that mango was marketed in the form of grade A/Band grade C (non grade). Grade A/B had two marketing channels, namely; (i) farmers – collector – wholesaler –agent – fruit shop – consumer and (ii) farmers – collector – wholesaler – agent – supplier – supermarket –consumer. While grade C had one channel, namely (iii) farmers – collector – wholesaler – nonstore retailer –consumer. The first channel got marketing margin of Rp.10,920,- coming from wholesaler (48.1%), fruit shop(35.4%), agent (14.2%) and collector (2.3%). The second channel got marketing margin of Rp.15,000,- comingfrom wholesaler (34.9%), supplier (26.6%), supermarket (26.6%), agent (10.2%) and collector (1.7%). Theproblems in marketing were the farmers have a low bargaining position in determining the mango’s price, theamount and quality of product did not always accord to market request, the farmers that have weak capital wereoften fallen on money lender and there were found the illegal charges in activity of transportation. Somerecommended efforts in farmer’s level, namely to increase the farmer’s knowledge and skill to produce mango’squality according to market request by low cost technology, to improve the farmer’s accessibility to marketinformation inclusive of request, variation of seasonal price and trend price thereby they can plan the mango sale toreach effective, efficient and profit sale.Key words: mang, marketing analysis, West Java

Theobjectives of research were to know the appropriate Macadamia’s seed size for seedling. This research was heldat The Research Institute of Spices and Industrial Crop (Balittri) in Pakuwon, Parungkuda, Sukabumi, West Javaon April 2006 until April 2007. the experimental design of research was using randomized block design with 3treatment and 9 replications. The treatment were: A (large seed: seed weigh was 6-7 g, seed diameter was 2.1-2.3cm), B (middle seed: seed weigh was 5-6 g, seed diameter was 1.8-2.0 cm), C (small seed: seed weigh was 4-5g, seed diameter was 1.5-1.7 cm). The amount of tree sample for every treatment were 45 tree, so for whole therewere 135 tree. Variable consist height, stem diameters, number of branch’s and leaves , length and width ofleaves. Result of research showed that seed size for medium and large have better growth than smaller seed, thusseed size for medium and large for all variable did not show significant difference, i.e. plant weight was 26.63cm, stem diameter was 0.50 cm, amount of branch was 0.50 branch, lenght of leaves was 17.68 cm and width ofleaves was 2.72 cmKey Words: macadamia, Macadamia integrifolia, size, seed, growth

Abstract

Yied and agronomic characters performance of ten superior rice varieties in Sleman, Yogyakarta. Study onyied and agronomic characters performance usin superior rice varieties was conducted at Blendangan,Tegaltirto,Berbah, Sleman, Yogyakarta from June to September of 2015. Six superior rice varieties namely Sidenuk, Inpari1, Inpari 10, Inpari 19, Inpari 23, and Inpari 30 were planted using seedling of 15 days with one seedling per hillin jajar legowo 4:1 system, with plant spacing of 25 x 12,5 x 50 cm. Plot size per variety was 1000 m2.Meanwhile,four populair varieties such as Sintanur, Pepe, Ciherang, and Situ Bagendit planted using the same populationby farmers were used as checks. Data were analyzed using t test. Inpari 19 and Inpari 30 gave the highest yield of7.5 and 7.3 t/ha, respectively, compared with check varieties and the other varieties tested. The highest yield onInpari 19 and Inpari 30 were contributed by the highest of the number of filled grains, total grain number, andthe panicle number. Inpari 19 showed earliest maturity (104 days), meanwhile, the other varieties were mediummaturity (107-124 days). Inpari 19 gave the highest profit compared with the others superior varieties tested andthe most preferred by farmers because of more taste, more white color, more shiny, and more fragrant.Key words: yield, agronomic characters, Inpari, “jajar legowo” ABSTRAKPenampilan hasil dan karakter agronomi sepuluh varietas unggul di Sleman, Yogyakarta. Pengkajianterhadap penampilan hasil dan karakter agronomi menggunakan varietas unggul padi dilaksanakan diBlendangan,Tegaltirto, Berbah, Sleman, Yogyakarta dari Juni hingga September 2015. Enam varietas yaituSidenuk, Inpari 1, Inpari 10, Inpari 19, Inpari 23, dan Inpari 30 ditanam dengan bibit berumur 15 hari dengan satubibit per lubang pada teknik jajar legowo 4:1, dengan jarak tanam 25 x 12,5 x 50 cm. Ukuran plot size per varietasadalah 1000 m2. Sedangkan empat varietas yang sudah dikenal petani yaitu Sintanur, Pepe, Ciherang, dan SituBagendit ditanam dengan cara yang sama oleh petani digunakan sebagai pembanding. Data dianalisismenggunakan uji t. Inpari 19 dan Inpari 30 masing-masing memberi hasil tertinggi sebesar 7,5 dan 7,3 t/ha,dibandinkan dengan varietas pembanding dan varietas lain yang dikaji. Hasil tertinggi pada Inpari 19 dan Inpari30 dikontribusi oleh jumlah gabah isi, jumlah total gabah dan jumlah malai yang tinggi. Inpari 19 menunjukkanumur paling cepat (genjah) yaitu 104 hari, sementara varietas lainnya berumur sedang (107-124 hari). Inpari 19memberi keuntungan tertinggi dibandingkan dengan varietas unggul lainnya, dan paling disukai petani karenalebih pulen, lebih putih, lebih berkilap, dan lebih wangi.Kata kunci: hasil, karakter agronomi, Inpari, “jajar legowo”
