Abstract

Penelitian ini bertujuan untuk mengetahui parameter genetik dan korelasi antar sifat-sifat morfologi kelapa. Bahan lanaman yang digunakan adalah 19 populasi kelapa lokal hasil koleksi dan beberapa pulau di Indonesia, ditanam di Kebun Percobaan Pakuwon, Jawa Barat pada tahun 1978 dan 1982. Tinggi tempat 450 m di atas permukaan laut dengan tipe iklim Bl menurut Oldeman. Jumlah tanaman 100 pohon, dengan jarak tanam 9 m x 9 m scgi empat untuk kelapa Dalam dan 60 pohon kelapa Genjah dengan jarak tanam 7 m x 7 m scgi empat sciiap populasi. Pengamatan dilaksanakan dalam dua lahap Mei-Agusius 1996 pada 14 populasi dan Juni-Agustus 2000 pada 5 populasi saat tanaman kelapa berumur 18 tahun. Tanaman yang diamati 4 pohon diulang 3 kali setiap populasi sehingga total tanaman yang digunakan dalam penelitian ini adalah 19x4x3 « 228 pohon. Sifat yang diamati meliputi sifat-sifat morfologi batang, daun dan rangkaian bunga Hasil penelitian menunjukkan bahwa variabilitas genetik sifal-sifal morfologi kelapa umumnya sempil. Beberapa sifat seperti: diameter batang 1,5 m dai permukaan lanah, panjang batang 11 bckas daun, langkai bunga tanpa bunga betina, dan jumlah bunga betina menunjukkan variabilitas genetik yang luas Pada umumnya hcritabilitas dalam am luas dan kemajuan genetik dalam persen untuk semua sifat tinggi, kecuali hentabilitas sifat tangkai bunga membawa bunga betina bemilai sedang. Terdapat korelasi genetik positif yang nyata pada sifat-sifat morfologi batang dengan daun dan rangkaian bunga, kecuali dengan jumlah bunga betina/tandan dan jumlah tandan/ph/lh. Dari 15 sifat yang diamati, hanya 6 sifat yang mempunyai korelasi genetik nyata dengan sifat jumlah bunga betina/tandan yaitu: diameter batang 1.5 m dari permukaan lanah (rg = -0.5215*), panjang batang 11 bckas daun (rg • -0.5369*), lebar anak daun (rg ■ -0.5961**), tebal tangkai landan (rg = 0.5802**), panjang rangkaian bunga (rg ■ -0,6143**), dan panjang tangkai bunga (rg = -0.4907*), sehingga sifat-sifat tersebut dapat digunakan sebagai kiteia seleksi untuk memperoleh jumlah bunga betina banyak per mayang pada lanaman kelapa.Kata kunci: Kelapa, parameter genetik, korelasi, sifat morfologi ABSRACT Estimation of Genetic Parameters and Correlation Between Morphological Traits in Coconut (Cocos nucifera, Linn)The objective of this experiment was to determine genetic parameters and correlation between morphological trails on the coconut population. A total of 19 local coconut populations were collected from some islands in Indonesia, planted at Pakuwon Experimental Garden, West Java in 1978 and 1982. The altitude is 450 meters above sea level with climate type Bl Oldeman. The total number of sample is 100 palms for each tall coconut with planting distance 9 x 9 m and 60 palms for each dwarf coconut with planting distance 7 x 7m. The observation was done in two steps i.e.: May - August 1996 on 14 populations and June - August 2000 on 5 populations when the coconut population was 18 years old. A number of 4 palms with 3 replications were observed of each population to measure morphological traits of he stem, leaf and inflorescence. Therefore, the total palms used in the experiment were 19 x 4 x 3 = 228. The results revealed that the genetic vaiability of coconut morphological trait were generally narrow. A few traits i.e.: stem diameter 1 5 m from ground level, stem length of 11 leaf scars, spadix without female flower, and number of female flowers/bunch showed a wide degree of variability. In general, the heritabilily estimates in broad sense and genetic gained in percent for all trails were high, except the henlability of spadix with female flower Irait was lowly. A positive significant genetic correlation were found to the morphology traits of stem with leaf and inllorcsccncc except Uic number of female flower/bunch and number of bunch/palm/ycar. From fifteen traits, only six traits had significant genetic correlation with the number of female flower Ihcy were diameter stem 1 5 m from ground level (rg 0.5215*), stem length of 11 leaf scars (rg - -0.5369'), leaflet width (rg - -0.5961**), peduncle thickness (rg 0.5802**), length of inflorescence (rg -0.6143**), and length of spadix (rg -0.4907*), and these traits could be used as selection criteria for selecting high female flower bunch on the coconut.Keywords ;Cocos nucifera. genetic parameters, correlation, mor- phological trails

Abstract

Fulvic acid is an extraction product of humus which is very potential for supplement fertilizer and able to reduce either inorganic or organic fertilizer application. The information about fulvic acid application as supplement fertilizer on ginger in Indonesia is still limited. The objective of the study was lo find oul the efect of fulvic acid as supplement fertilizer on the growth, productivity and quality of young ginger. A green house trial was conducted from July lo November 1996. Five levels of fulvic acid concentration, 0, 2.5, 5, 7.5, and 10% were sprayed every week from 4 to 1 5 weeks ater planting (WAP). A randomized block design was used with five replicates. The results indicated that the growth of plant height and number of tiller of ginger increased rapidly al 8 WAP, then il became slowly from 12 lo 1 5 WAP Application 10% of fulvic acid was able to increase vegetative parts 99.6%, fresh and dry weight of rhizome 89 and 125% respectively, and starch content of rhizome 22.6%. To find oul of the optimal effect of fulvic acid on productivity and quality of ginger, a further research using higher level and application frequency of fulvic acid as an extract product from several humus types in Indonesia is needed.

Abstract

Area and pepper production in Lampung were decreased from time to time and potential to become extinct if it isn’t immediate treatment seriously. The study were to analyze the effect of internal factors of farming management on pepper productivity in Lampung Province which is expected to provide benefits for preparing pepper development policy in the future. The study was conducted in North Lampung, East Lampung, and Way Kanan regency, from January to December 2014. The study used survey methods and interview with structured questionaire with sample of 180 people which are stratified by: a) farmers who have planted pepper but he is not planting pepper anymore; b) farmers growing pepper with conventional  technology introduction; and c) farmers who plant pepper with recommendations technology package of  IAARD. The results showed that technically of internal pepper farm management factors that affect on pepper production in Lampung is acreage, NPK Phonska, SP36 fertilization, and application of pepper monoculture cropping. Efforts to increase pepper production in Lampung could be achieved through the addition of pepper acreage supported with intensive handling pepper plants through cultivation technology properly such as NPK Phonska fertilization, SP36 fertilization, and the application of pepper monoculture cropping. The development of a relatively good price of pepper last two years should be a momentum for the revival pepper in Lampung. Support technological innovation needs to be improved through the assistance and support on the implementation of SOP accompanied by an increase farmers' access to production inputs especially fertilizer.Keywords: pepper, technical factor, socioeconomic factor, productivityAbstrakLuas area dan produksi lada di Provinsi Lampung terus berkurang dari tahun ke tahun dan terancam punah jika tidak segera dilakukan penanganan secara serius. Penelitian ini bertujuan untuk menganalisis pengaruh pengelolaan faktor internal usahatani terhadap produktivitas lada di Provinsi Lampung yang diharapkan dapat memberikan manfaat dalam penyusunan kebijakan pengembangan lada ke depan . Penelitian dilakukan di Kabupaten Lampung Utara, Lampung Timur, dan Way Kanan, mulai bulan Maret sampai Desember 2014. Kajian ini menggunakan metode survei dan wawancara dengan bantuan kuisioner terstruktur dengan jumlah petani sampel 180 orang yang distratifikasi berdasarkan: a) petani yang pernah menanam lada tetapi saat ini tidak lagi menanam lada; b). petani yang menanam lada dengan introduksi t eknologi minimal (konvensional dan seadanya); dan c) petani lada yang menanam lada dengan rekomendasi paket teknologi Badan Litbang Pertanian. Hasil penelitian menunjukkan bahwa pengelolaan faktor internal usahatani lada yang mempengaruhi produksi lada di Lampung adalah luas areal, pemupukan NPK Phonska, pemupukan SP36, dan penerapan pola tanam lada monokultur. Upaya peningkatan produksi lada di Lampung dapat ditempuh melalui penambahan luas areal lada yang didukung dengan penanganan intensif melalui penerapan teknologi budidaya dengan benar seperti pemupukan NPK Phonska, SP36, dan penerapan pola tanam lada monokultur. Perkembangan harga lada yang relatif baik pada dua tahun terakhir dapat dijadikan momentum untuk kebangkitan kembali perladaan di Lampung. Dukungan inovasi teknologi perlu ditingkatkan melalui pendampingan dan pengawalan penerapan SOP disertai peningkatan akses petani terhadap input produksi terutama ketersediaan pupuk.Kata kunci: lada, faktor teknis, sosial-ekonomi, produktivitas

Abstract

Sustainability analysis of rubber tree (Hevea brasiliensis) farming system aimed to assess the sustainability of the application of farming models which was developed in a pilot project in degraded peatland, which is located in Village/District Jabiren, Regency Pulangpisau (Central Kalimantan). Research was conducted by a structural survey method with 30 selected respondent farmers around the plots. The analysis was performed with the multidimentional scaling (MDS) approach, including social, economic and environmental dimensions. The level of (lkb) farming system sustainability of rubber trees in degraded peatland based on values of sustainability index of multidimensional in the Jabiren District showed sustained considerable scale with an index value of 66.69, meaning that farming models developed are quite sustainable farming. In other words that farming models are economically beneficial, socially acceptability to society, and ecologically not damage the environmental. The social dimension is more dominant determine the sustainability of farming that contributes to IKB amounted to 72.65 compared with the economic and environmental dimension with a contribution value of each 68.11 and 57.25. Sensitive factors affecting the sustainability, include: the intensity of extention (the social dimension), the stability of the prices of the farmers surplus productivity (the economic dimension), the water pH and water level fluctuations (the ecological dimensions).Keywords: sustainability index, rubber farming system, degraded peatland AbstrakAnalisis keberlanjutan usahatani tanaman karet bertujuan untuk menilai tingkat keberlanjutan dari aplikasi model usahatani yang dikembangkan dalam suatu demplot pola tanam (intercropping) di lahan gambut terdegradasi, dengan tanaman pokok tanaman karet dengan tanaman sela nenas di antara tanaman pokok karet dan aplikasi amelioran, yang berlokasi di Desa/Kecamatan Jabiren, Pulangpisau (Kalimantan Tengah). Penelitian dilakukan dengan metode survei terstruktur dengan memilih 30 responden petani di sekitar demplot. Analisis dilakukan dengan pendekatan multidimensi (multidimentional scaling/MDS), meliputi dimensi sosial, ekonomi dan dimensi lingkungan. Tingkat keberlanjutan (Ikb) usahatani tanaman karet di lahan gambut terdegradasi yang didasarkan pada nilai indeks keberlanjutan multidimensi di lokasi penelitian menunjukkan skala cukup berkelanjutan dengan nilai indeks 66,69, artinya model usahatani yang dikembangkan cukup berkelanjutan. Dengan kata lain bahwa model usahatani tersebut memberi manfaat secara ekonomi, secara sosial dapat diterima masyarakat, dan secara ekologis tidak merusak lingkungan. Dimensi sosial lebih dominan menentukan keberlanjutan usahatani yaitu kontribusi terhadap Ikb sebesar 72,65 dibanding dengan dimensi ekonomi dan lingkungan dengan kontribusi nilai masing-masing 68,11 dan 57,25. Faktor yang peka mempengaruhi keberlanjutan, meliputi: intensitas penyuluhan (dimensi sosial), kestabilan harga hasil petani pada saat panen (dimensi ekonomi), pH air di lahan usahatani dan fluktuasi debit air di lahan petani (dimensi lingkungan/ekologi).Kata kunci: indeks keberlanjutan usahatani karet, lahan gambut terdegradasi

Abstract

Genetic variability of selfing Mapanget Tall coconut No. 32 based on RAPD markerThe objective of this study was to analyze the genetic variability of seling Mapanget Tall coconut No. 32 used RAPD marker. Ihe method of morphology, fruit component and isozymc analyses could not explain the homozygote level of the offspring and his parents. The DNA analysis was done at Plant Biology Laboratory, PAU, Life Science IPB, and the coconut leaflets samples were collected from Kima Atas Research Instalation, Research Institute for Coconut and Palmae, Manado. This research the study was conducted from November 1999 to Fcbruay 2000. Coconut materials analyzed were DMT 32-OP, DMT 32-S2, DM 1 32-S3 andDMT32-S4. DMT 32-S2 was the offsprings of the selfcd DMT 32- SI coconut seling. and the DMT 32-SI came from the sclfed of DMT 32-OP. Then selfcd DMT 32-S2 produced were found the DMT 32-S3. and selfcd of DMT 32-S3 produced the progeny of DMT 32-S4. DNA was isolated using the method of ROHDE et at (1995), while DNA quantity and quality was using the method of SAMBROOK et al (1989). Then the DNA was ampliied using 10 random primer 10 mer and PCR apparatus of 2.400 Perkin-Elmer System. Ater thai the DNA was elcctrophorated, and photographed using Polaroid 667 ilm, then ihe biner data matrix of each coconut population was calculated lor Ilic number of monomorphism banding was found in DMT 32-S2. Ihe genetic similarity between DMT 32-S3 and DMT 32-S3 was the mosl similar at genetic distance of 90%. DMT 32-S3 resulted from self pollination can be recommended as parent material for hybridization.
