ABSTRAKHelopeltis antonii merupakan salah satu hama pada tanaman kakao,teh, dan jambu mete yang menyerang pucuk dan buah dengan menusukkanstiletnya untuk mengisap cairan sehingga menyebabkan kerusakan.Penelitian bertujuan menguji toksisitas ekstrak buah Piper retrofractum(cabai jawa) terhadap imago, pengaruh konsentrasi subletal terhadap nimfaketurunan, persistensi terhadap mortalitas dan oviposisi H. antonii.Penelitian dilaksanakan di Laboratorium Fisiologi dan ToksikologiSerangga, Institut Pertanian Bogor dan Laboratorium Proteksi Tanaman,Balai Penelitian Tanaman Industri dan Penyegar Sukabumi, mulai Mei2013 sampai April 2014. Buah mentimun digunakan sebagai inangpengganti untuk perbanyakan serangga uji H. antonii di laboratorium danmedia pengujian. Hasil penelitian menunjukkan kematian imago H.antonii, akibat perlakuan ekstrak P. retrofractum 0,05-0,3%, sudah terjadipada 24 jam setelah perlakuan (JSP). Sementara itu, pada 24 dan 48 JSPterjadi penurunan tingkat kematian H. antonii. Setelah 48 JSP, hanyaterjadi sedikit peningkatan kematian H. antonii. LC 50 dan LC 95 ekstrak P.retrofractum pada 120 JSP masing-masing 0,20 dan 0,49%. Jumlah nimfaketurunan yang dihasilkan pada perlakuan subletal ekstrak P. retrofractum0,203% (LC 50 ) lebih sedikit dibandingkan dengan konsentrasi 0,141%(LC 25 ). Ekstrak P. retrofractum yang dipajankan di bawah sinar mataharihingga 5 hari masih efektif terhadap imago (mortalitas 80%), tetapi tidakefektif dalam menghambat peletakan telur H. antonii. Penghambatanpeletakan telur terhadap imago H. antonii pada perlakuan ekstrak P.retrofractum 0,98% (2 × LC 95 ) yang dipajankan di bawah sinar matahariselama 0 dan 1 hari, dengan indeks penghambatan oviposisi 22,7 dan23,8%. Keefektifan ekstrak P. retrofractum perlu diuji di lapangan untukmenilai kelayakan dalam pengendalian H. antonii.Kata kunci: insektisida botani, mortalitas, oviposisi, persistensiABSTRACTHelopeltis antonii is cocoa, tea, and cashew nuts important pest thatcauses damage by sucking plant sap from shoots and nuts. This study wasconducted to test toxicity of Piper retrofractum fruit extract on adults,sublethal effect on the production nymphal progeny, and persistenceagainst mortality and oviposition of H. antonii. This study was conductedat The Fisiology and Insect Toxicology Laboratory, Plant ProtectionDepartement, Bogor Agricultural University and The Plant ProtectionLaboratory of Indonesian Industrial and Beverage Crops Research Institutefrom Mey 2013 to April 2014. Cucumber was used as a host substitute forrearing the test insect and as the testing medium.

Abstract

ABSTRACTHigh Cl content of tobacco might have negative effect on quality. The study tried to find out correlation between added Phonska fertilizer to rice planted before tobacco on tobacco Cl content. The objective was to determine the effect of added Phonska (10.8% Cl) to rice planted before tobacco on tobacco Cl content and quality. The study was carried out in the area of tobacco in five districts of Jombang, East Java Province from May to November 2012. Collecting data was done using survey method to the tobacco farmers and soil and tobacco samples were collecting from 100 points which were distributed in five districts based on land use map. The results showed that the most tobacco farmers (67%) added Phonska to the rice planted before tobacco. Addition of Phonska each year had caused accumulation of Cl in soil with high level >2% (90%). Based on analysis of variance it was known that tobacco Cl content was strongly influenced by Phonska addition to rice planted before tobacco plants (PPP) and soil Cl content, but not influenced by Phonska as starter to tobacco plants (PPT). The corelation was expressed by equation: leaf Cl = 0.4266 x exponential ((0.367 PPP*) - (0.314 PPT) + (0.388 soil Cl*))*.Keywords: Nicotiana tabacum L., quality, Phonska fertilizers, Cl HUBUNGAN ANTARA PUPUK PHONSKA PADA PADI DAN KADAR Cl TEMBAKAU DI JOMBANG, JAWA TIMURABSTRAKTingginya kadar Cl dalam daun tembakau adalah salah satu penyebab rendahnya mutu tembakau. Cl tembakau bisa berasal dari pemupukan seperti Phonska (10,8% Cl) atau dari tanah. Penelitian observasi ini bertujuan untuk mengetahui pengaruh penggunaan pupuk Phonska (10,8% Cl) pada padi terhadap mutu dan kadar Cl tembakau yang ditanam setelah padi. Kegiatan penelitian dilaksanakan pada areal penghasil tembakau di lima kecamatan Kabupaten Jombang mulai bulan Mei sampai Nopember 2012. Survei pendahuluan untuk penentuan 100 satuan titik lokasi dilakukan secara proporsional yaitu berdasarkan prosentase terhadap luas areal tanaman tembakau dan mewakili bekas lahan padi yang tidak dipupuk dan yang dipupuk Phonska dari lima kecamatan berdasarkan peta penggunaan lahan. Pengumpulan data dilakukan dengan menggunakan metode survei, yaitu wawancara petani tembakau tentang penggunaan pupuk phonska pada padi dan tembakau, pengambilan sampel tanah dan daun tembakau. Penilaian mutu/harga tembakau oleh grader pabrik rokok. Sampel tanah dan daun tembakau dianalisis kadar Cl di Laboratorium Mutu Hasil Balai Penelitian Tanaman Pemanis dan Serat. Data hasil pengamatan dianalisis secara deskriptif yaitu klasifikasi berdasarkan persentase kejadian. Untuk  mengetahui hubungan atau pengaruh antar variabel dilakukan analisis regresi menggunakan program SPSS. Dari hasil survei diketahui bahwasebagian besar petani (67%) menggunakan pupuk Phonska untuk tanaman padi sebelum tembakau dan akumulasi Cl tanah tergolong tinggi >2% (90%). Dari hasil analisis sidik ragam diketahui bahwa kadar Cl daun tembakau sangat dipengaruhi oleh pemupukan Phonska pada padi sebelum tanaman tembakau (PPP) dan kadar Cl tanah, tetapi tidak dipengaruhi oleh pemupukan Phonska pada Tembakau (PPT) sebagai starter. Hubungan pemupukan Phonska,  Cl tanah, dan Cl daun tembakau tersebut diekspresikan dengan model persamaan : Cl daun = 0,4266 x exponensial ((0,367 PPP*) – (0,314 PPT) + (0,388 Cl tanah*))*.Kata kunci : Nicotiana tabacum L., mutu, pupuk Phonska, Cl

Abstract

In vitro conservation of black pepper (Piper nigrum L.)Black pepper (Piper nigrum L.) is one of the economically im¬ potant spices. The major constraint in black pepper cultivation and conservation in ield is foot rot disease caused by Phytopthora capsici which could cause plants die. Conservation of black pepper germplasms as living collections in ield is risky due to pests and natural disaster. The experiment on in vitro cop ervation of black pepper var. LDL was conducted al the laboratory of Plant Genetic Resources and Breeding, Research Institute for Spice and Medicinal Crops (RISMC) Bogor from April 1998 to Maret 1999. Single node cuttings from sterile culture were used as explains. The explains were cultured on Murashige and Skoog (MS) medium on full and half strength concentration supplemented with paclobutrazol (paclo) (0, 1, 3 and 5 mg/1). The experiment was performed in a randomized complete block design arranged factorially with 10 replications. The result showed that the medium supplemented with paclo on both full MS and MS A medium could suppress vegetative growth until 12 months. There was no signiicant interaction between medium and paclo on shoot initiation. The effect was signiicant on shoot height, number of leaves and culture performances. Increasing paclo concen¬ tration caused higher suppression of plant growth. MS A medium supplemented with paclo 5 mg/1 showed the slowest growth with shool height 2.10 cm and number of leaves 9. Culture performance was fresh, with green leaves and vigorous. Advcntive shoots were able to regenerate on the medium supplemented with BA 0.3 mg/1. In vitro conservation of black pepper with paclo did not change plant regeneration ability. Therefore, this technique may be used as an altenative method for black pepper conservation.

Abstract

ABSTRAKRata-rata produksi jambu mete Indonesia masih rendah (350 kggelondong/ha/tahun), dibandingkan dengan India dan Brazil (800 – 1000kg gelondong/ha/tahun). Hal itu antara lain disebabkan oleh teknikbudidaya yang masih tradisional, rendahnya mutu bibit, dan kurang ter-sedianya pohon induk sebagai sumber benih. Berdasarkan permasalahantersebut, telah dilakukan percobaan penyambungan 1 varietas dan 3 nomorharapan jambu mete. Tujuannya adalah untuk mendapatkan bibit hasilsambungan bermutu tinggi, sebagai dasar pendirian kebun benih jambumete. Percobaan dilakukan di Kebun Percobaan Muktiharjo, Jawa Tengah,bulan Januari - Desember tahun 2001. Percobaan disusun dalam rancanganpetak terbagi (RPT) dengan 3 ulangan. Petak utama adalah 4 jenis batangatas yaitu: Gunung Gangsir 1, Gunung Gangsir 2, Muktiharjo 1 danMuktiharjo 2. Anak petak adalah empat jenis batang bawah yaitu: GunungGangsir 1, Gunung Gangsir 2, Muktiharjo 1 dan Muktiharjo 2. Parameteryang diamati adalah keberhasilan penyambungan pada fase pembibitan,data pertumbuhan tanaman (tinggi tanaman, diameter batang, diameterkanopi, jumlah cabang primer, sekunder dan tersier). Hasil percobaanmenunjukkan bahwa penyambungan batang bawah Muktiharjo 1 denganbatang atas Muktiharjo 1 dan Muktiharjo 2, menghasilkan persentasekeberhasilan penyambungan tertinggi (50%). Penyambungan denganGunung Gangsir 1 sebagai batang bawah dan Muktiharjo 1 danMuktiharjo 2 sebagai batang atas, keberhasilan penyambungannya palingrendah (38,89%). Tidak ada interaksi antara batang atas dan batangbawah terhadap pertumbuhan tanaman. Batang atas berpengaruh nyataterhadap jumlah daun, tetapi tidak berpengaruh terhadap tinggi tanaman,diameter batang, dan lebar kanopi. Penyambungan Gunung Gangsir 1 danMuktiharjo 2 sebagai batang atas, menghasilkan pertumbuhan tanamanyang lebih baik dibandingkan dengan batang atas Gunung Gangsir 2 danMuktiharjo 1. Penyambungan Gunung Gangsir 1, Gunung Gangsir 2, danMuktiharjo 1 sebagai batang bawah menghasilkan diameter batang dantinggi tanaman lebih baik dibandingkan Muktiharjo 2. Setelah tanamanmencapai umur 3 tahun, batang atas tidak berpengaruh terhadap pertum-buhan tanaman, sedangkan batang bawah memberikan pengaruh terhadappertumbuhan tanaman. Pertumbuhan tanaman terbaik diperoleh padatanaman dengan batang bawah Gunung Gangsir 1.Kata kunci : Jambu mete, Anacardium occidentale L., klon, penyam-bungan, batang bawah, batang atas, pertumbuhan, JawaTengahABSTRACTEffect of scion and root stock on successful grafting ofcashew plantCashew nut production of Indonesia is lower (350 kg/ha/year)compared to India and Brazil (800 and 1000 kg/ha/year). There are manyfactors causing low production of cashew in Indonesia such as lowcultivation technology, poor quality of seedlings and insufficient of motherplants. The purpose of the research was to find out good quality seedlingsfrom grafting as a basic to establish cashew mother plants gardens. Theexperiment was conducted in Muktiharjo Experimental Garden, CentralJava, in 2001. The experiment was arranged in split-plot design with 3replications. The main plot was 4 kinds of scions namely Gunung Gangsir1, Gunung Gangsir 2, Muktiharjo1 and Muktiharjo 2. The sub plot was 4kinds of root stocks the same as the scions. Variables observed weresuccessful grafting at nursery phase and plant growth such as height ofplants, diameter of trunk, diameter of canopy, and number of primer,secondary and tertiary branches. The results of experiment showed thatgrafting by using clone Muktiharjo 1 as root stock, and Muktiharjo 1 andMuktiharjo 2 as scions produced the highest percentage of successfulgrafting (50%). Grafting by using Gunung Gangsir 1 as root stock and,Muktiharjo 1 and Muktiharjo 2 as scions produced the lowest percentageof successful grafting (38.89%). There were no significant interactionsbetween root stock and scion on the growth of cashew plant. Scion hadsignificant effect on the number of leaves, but, it did not have significanteffect on the plant height, diameters of trunk and diameters of canopy.Grafting by using Gunung Gangsir 1 and Muktiharjo 2 as scions producedbetter plant growth compared to those of Gunung Gangsir 2 andMuktiharjo 1 as scions. Grafting by using Gunung Gangsir 1, GunungGangsir 2 and Muktiharjo 1 as root stocks produced diameter of trunk andheight of plants better than that of Muktiharjo 2 as rootstock. At 3 yearsold after planting, scions did not significantly affect the plant growthneither did their interaction. While rootstock significantly affected thegrowth of cashew plant. As a rootstock, Gunung Gangsir 1, produced thebest cashew plant growth compared to other clones.Key words: Cashew, Anacardium occidentale L, clones, grafting,rootstock, scion, growth, Central Java

Abstract

The stability of yield and quality of the new lines of Temanggung tobaccoThe productivity of Temanggung tobacco is relatively low. One of the causes of the low productivity is genetic deterioration. Fom a series of selection, four lines were potential to be developed. Befoe the new varieties are released they need to be tested at different locations in a central poducing area. The tests were conducted at 1 1 locations in Temanggung District rom 1995 to 1997. The lines tested included four selected lines, original population of Temanggung tobacco.from which the selected lines were produced, and Kemloko, a local variety generally planted by farmers. The trial, were designed as a randomized block in three replicates for respective location. Results showed that two of four tested lines i.e. 2258/2/1/1 and 2132/2/2/1/1 produced stable yield and quality. Compared with Kemloko (local variety) the dry sliced tobacco, grade index and crop index of 2258/2/1/1 increased by 17.57, 6.85, and 26.88% respectively and those of 2132/2/2/1/1 increased by 12.28, 16.03, and 31.88% respectively.

ABSTRAKPala merupakan tanaman asli Indonesia dan informasi keragaman-nya masih terbatas. Keragaman spesies dan varietas pala penting untuk dievaluasi sebagai dasar tindakan konservasi. Keragaman varietas danspesies pala dapat dievaluasi dengan mengamati keragaman morfologi dan fenotipe di lapangan. Penelitian yang dilakukan bertujuan mengevaluasi keragaman fenotipik di antara aksesi pala dan mengevaluasi pengelompokan intra dan inter spesies pala dari Maluku Utara. Populasi pohon pala yang berumur minimal 15 tahun dari Tidore dan Patani, Halmahera Tengah, Maluku Utara digunakan dalam penelitian. Aksesi yang digunakan terdiri atas spesies Myristica fragrans, Myristica fatua, Myristica argentea, Myristica succedane, dan sejumlah aksesi yang tidak diketahui nama spesiesnya. Hasil evaluasi menunjukkan aksesi pala dari Patani dan Tidore menunjukkan variasi yang tinggi dalam bentuk buah, warna buah tua, dan bentuk biji. Hanya aksesi pala asal Tidore yang menunjukkan variasi dalam bobot fuli. Dendogram yang dibuat berdasarkan karakter fenotipe menjelaskan aksesi pala yang dianalisis ke dalam empat kelompok pada indeks kesamaan 70%. Kelompok pertama terdiri atas dua aksesi M. fatua dan satu aksesi pala yang tidak diketahui spesiesnya dari Tidore serta satu aksesi M. fragrans.

ABSTRAKAir kelapa dan daging kelapa muda memiliki rasa dan aroma khas,namun kelezatannya tidak bisa dinikmati setiap saat oleh setiap orang,karena umur simpan kelapa muda terbatas dan sulitnya distribusi. Salahsatu cara yang dapat dilakukan untuk memperpanjang masa simpan danmempermudah distribusi adalah melalui proses pengeringan, misalnyadengan spray drier. Bahan pangan yang dikeringkan dengan spray drierharus berupa suspensi dan hasil akhir bentuk serbuk. Penelitian dilakukandengan mengeringkan campuran air kelapa dan daging buah kelapa mudadengan spray drier. Tujuan penelitian untuk mengetahui pengaruhperbandingan antara air kelapa dan daging buah kelapa muda terhadapmutu serbuk minuman kelapa selama penyimpanan. Penelitian disusunsecara faktorial dalam rancangan acak lengkap. Faktor A, kematangan airkelapa : (A1) tua dan (A2) muda. Faktor B, penambahan daging kelapamuda : (B1) 15%, (B2) 20% dan (B3) 25%. Faktor C, lama penyimpanan:(C1) 0 bulan, (C2) 1 bulan, dan (C3) 2 bulan., (C4) 3 bulan dan (C5) 4bulan. Ulangan 2 kali. Pengamatan terdiri dari : kalium, serat pangan,warna, aroma dan rasa, total mikroba, pH, total padatan, total asam dankadar air. Hasil penelitian menunjukkan total padatan Serbuk MinumanKelapa (SMK) berkisar 7,59-9,50%, pH 4,94-5,35 dan total asam 25,85-43,90. Serat pangan 4,70-5,54%, kalium tertinggi pada air kelapa tuadengan penambahan daging kelapa muda 20%, yaitu 1.328,58 mg/100 g.Sedangkan kadar air 5,15- 7,84%. Warna 3,617-3,719 (biasa sampai suka);aroma 3,000 – 3,960 (biasa sampai suka), dan rasa manis 2,500-3,640(suka). Total mikroba SMK 3,72- 4,43 log CFU/g. Kematangan air kelapaberpengaruh terhadap kadar serat pangan. Penambahan daging kelapamuda berpengaruh terhadap kadar serat pangan dan warna. Lamapenyimpanan berpengaruh terhadap total padatan. Interaksi kematangan airkelapa, penambahan daging kelapa muda dan lama penyimpanan ber-pengaruh terhadap pH, total asam, aroma, rasa dan total mikroba.Berdasarkan skor rasa, kadar air, kalium, serat pangan dan total mikroba,maka SMK yang memiliki mutu baik dan berpotensi dikembangkan adalahformula air kelapa tua dengan penambahan 20% daging kelapa muda.Kata kunci : Kelapa, Cocos nucifera, pengolahan, serbuk minuman,Sulawesi UtaraABSTRACTEffect of coconut water and young coconut kernel ratioand storage duration to the quality of coconut waterconcentrateCoconut water and young coconut kernel have unique flavor andodour. Since these products can not be kept longer and distributionproblem, so both of them are not available everywhere and anytime.Drying method with spray dryer equipment is a method to extend theproduct life product. Generally, spray dryer is used to make some foodproducts in powder form deriving from suspension. Raw materials used inthis experiment were coconut water from both of young and mature nutand young coconut kernel. The mixture was dried with spray dryer. Theobjective of this research was to find out the effect of coconut water andyoung coconut kernel ratio to the quality of coconut water concentrateduring storage. The experiment was arranged in factorial using completelyrandomized design with 2 replications. Factor A was maturity of coconutwater consist of (A1) young coconut water and (A2) mature coconutwater. Factor B was ratio of young coconut kernel and coconut water :(B1) 15%, (B2) 20%, (B3) 25%. Factor C was : storage duration consistof (C1) 0 month, (B2) 1 month, (B3) 2 months, (B4) 3 months and (B5) 4months. The variables were observed as follow : kalium content, fibercontent, colour, flavor, odour, total plate count, acidity, total soluble solid,total acid and water content. The results showed that coconut waterconcentrate had 7.59-9.50% of total soluble solid, acidity (pH) 4.94-5.35and total acid 25.85-43.90. By using 20% young coconut kernel in maturecoconut water obtained product with fiber content about 4.70-5.54% andhighest potassium content around 1,328.58 mg/100g. Score of organoleptictest as follow : colur is 3.617-3.719 (neither like nor dislike), odour is3.00-3.96 (neither like nor dislike to like) and flavor is sweet about 2.50-3.96 (like). Total plate count of coconut water concentrate is about 3.72-4.43 log CFU/g. Maturity of coconut water affected fiber content. Addingyoung coconut kernel affected total soluble solid. Whereas interaction ofcoconut water maturity, adding coconut kernel and storage durationaffected some variables like pH, total acid, odour, flavor and total platecount. Based on the results of flavour, moisture content, potassiumcontent, fiber content and total plate count showed coconut waterconcentrate had good quality. So it is potential to be developed. The bestformula is FORMULA E which was derived from mature coconut waterwith 20% young coconut kernel.Key words: Coconut, Cocos nucifera, processing, concentrate drink,North Sulawes
