Abstract

Budidaya jambu mete di Indonesia selama ini belum menggunakan varietas unggul sehingga mengakibatkan rendahnya produksi, yaitu sekitar 493 kg/ha/tahun. Peningkatan genetik terkendala oleh kurangnya informasi tentang variabilitas genetik jambu mete. Dalam merakit suatu varietas unggul diperlukan variabilitas genetik yang luas dari plasma nutfah yang tersedia. Tujuan dari penelitian ini adalah mengetahui tingkat kekerabatan dan keragaman genetik koleksi plasma nutfah jambu mete berdasarkan profil pita DNA menggunakan teknik RAPD. Penelitian dilaksanakan di Laboratorium Biologi Molekuler BB-Biogen, Bogor mulai bulan Mei-November 2010. Materi genetik yang digunakan adalah JN26, Oniki1, Oniki2, Oniki3, Kodi4, NDR31, Nigeria P9, Nigeria P2, JN7, Srilanka, Mojokerto, Pamotan, Karimun, Larantuka, BO2, SM9, JT21 dengan menggunakan 25 primer. Adapun kegiatannya meliputi pengumpulan materi koleksi plasma nutfah jambu mete (17 aksesi). Dilanjutkan kegiatan di Laboratorium dengan tahapan-tahapan kegiatan, seperti ekstraksi dan purifikasi DNA, loading dan running produk PCR dan analisis RAPD serta analisis data. Hasil penelitian menunjukkan dari dua puluh lima primer PCR-RAPD yang digunakan untuk mengamplifikasi sebanyak 17 sampel jambu mete, terdapat 24 primer yang memberikan pita DNA, 21 di antaranya polimorfisme dan tiga primer menunjukkan monomorfis. Hasil analisis kekerabatan 17 sampel jambu mete dengan program NTSys 2.1 menunjukkan bahwa terdapat variasi genetik yang cukup tinggi. Pada koefisien 88%, 17 jambu mete tersebut mengelompok menjadi lima, kelompok yang pertama terdiri dari delapan individu (Oniki1, Kodi4, JN26, NDR31, Srilanka, Mojokerto, Karimun, dan JT21), kelompok dua terdiri dari lima individu (Nigeria P9, B02, Nigeria P2, JN7, Pamotan), kelompok tiga terdiri dua individu (SM9, dan Larantuka), kelompok empat  terdiri dari satu individu (Oniki3), dan kelompok lima terdiri dari satu individu (Oniki2). Use of Random Amplified Polymorphic DNA (RAPD) Technique on grouping cashew (Anacardium occidentale L.) germplasmABSTRACT Many cashew plantations in Indonesia do not use superior variety. As a result, national cashew production is only 493 kg/ha/year. Genetic improvement is limited by the lack of information of genetic variability of germplasm. Wide genetic variability in cashew germplasms is necessary to produce superior variety. The purpose of this study was to evaluate the genetic variation and relationship of among cashew germplasms based on band pattern of DNA by using RAPD technique. The experiment was conducted at Molecular Biology Laboratory of BB-Biogen, Bogor since May till November 2009. Genetic materials used were JN26, Oniki1, Oniki2, Oniki3, Kodi4, NDR31, Nigeria P9, Nigeria P2, JN7, Srilanka, Mojokerto, Pamotan, Karimun, Larantuka, BO2, SM9, and JT21 by using 25 primers. The activity consisted of collecting of cashew germplasm (17 accessions), followed with laboratory activities such as: DNA extraction and purification, loading and running of PCR product, RAPD and data analysis. Results shows that 25 primers used were 24 primers shown DNA band pattern 21 of which there are polymorphism and 3 the monomorphism. Germplasm collection of cashew has wide variation. At 88% coefficient, 17 accessions of cashew were divided into five clusters. The first cluster  consisted of 8 individuals (Oniki 1, Kodi4, JN26, NDR31, Srilanka, Mojokerto, Karimun, dan JT 21), the second cluster of five individuals (Nigeria P9, B02, Nigeria P2, JN7, Pamotan ), third cluster two individuals (SM9 and Larantuka), the fourth cluster of one individual (Oniki3) and the fifth cluster consisted of one individual (Oniki2).

Penelitian untuk mengetahui pengaruh umur dan lama penyimpanan terhadap  pertumbuhan benih lada  telah dilakukan di Rumah Kaca Kebun Percobaan Sukamulya, Sukabumi, Jawa Barat mulai bulan Januari sampai dengan Desember 2011. Percobaan  disusun berdasarkan rancangan acak kelompok faktorial dengan tiga ulangan. Faktor Pertama adalah tiga taraf (umur benih), yaitu 1, 2, dan 3 bulan, sedangkan faktor kedua adalah 5 taraf (lama simpan benih), yaitu  0, 3, 5, 7 dan 9 hari. Jumlah sampel benih untuk pengamatan kondisi kesegaran sebanyak 50 bibit, sedangkan untuk pertumbuhan benih sebanyak 25 benih setiap perlakuan. Parameter yang diamati meliputi kondisi kesegaran benih setelah mendapat perlakuan penyimpanan dan pertumbuhan benih  umur 3 bulan. Parameter pertumbuhan terdiri atas  tinggi benih, jumlah buku, panjang daun, lebar daun, dan  panjang ruas. Data hasil pengamatan selanjutnya dianalisis menggunakan  analisis sidik ragam (anova) dilanjutkan dengan uji BNJ taraf 5%. Hasil penelitian menunjukkan bahwa interaksi antara umur benih dan lama penyimpanan berpengaruh terhadap kondisi kesegarannya, sedangkan umur benih dan lama penyimpanan berpengaruh terhadap pertumbuhan benih lada. Apabila benih lada dikeluarkan dari polibagnya, maka benih lada umur 2 bulan yang paling mampu bertahan terhadap penyimpanan dengan lama penyimpanan maksimal 5 hari. THE EFFECTS OF AGE AND STORAGE PERIODS ON THE GROWTH OF ROOTED CUTTINGS OF BLACK PEPPER ABSTRACT To provide good black pepper cuttings grown in polythene bags, it might be costly due to transportation cost should be covered into cost production. The use of rooted cuttings of black pepper is therefore considered as an alternative solution in providing of plant materials being ready to be planted in the fields. A research was carried out at a glass house of Sukamulya Research Station (Sukabumi) from January to Desember 2011. The objective of the study was to investigate the effects of age and storage periods of rooted cuttings on their freshness and growth performances under nursery condition. A randomized factorial design with three replications was used. The age of black pepper cuttings consisted of 1, 2, and 3 months old, while the storage periods were 0, 3, 5, 7 and 9 days. The number of pepper cuttings observed for their freshness levels were 50 cuttings per treatments, whereas those of their growth were 25 cuttings. For evaluation of their freshness, they were calculated based on the percentage of treated cuttings having water content of higher than 75%, while for their growth parameters observed were height of rooted cuttings, number of nudes, leaf length, leaf width, and length of internodes. The data were then analyzed with analysis of variance (anova) followed by HSD test level 5%. The results showed that there were noted interaction between the age and storage periods of rooted cuttings to the freshness and growth of young rooted cuttings. If farmers use rooted cuttings taken out from their polythene bags, then 2-month cutting olds with maximum storage periods of 5 days would give the best treated rooted cuttings having high in performance growth.

Abstract

Sebagian besar petani karet di Indonesia membuat bokar masih menggunakan koagulan yang dapat merusak mutu karet seperti pupukTSP, tawas, dan sejenisnya. Koagulan tersebut bersifat asam tetapi tidak mempunyai sifat antibakteri dan antioksidan sehingga bokaryang dihasilkan bermutu rendah dan berbau busuk. Penelitian dilaksanakan di perkebunan karet rakyat di Jawa Barat dari bulan Meisampai November 2012. Tujuan penelitian adalah mengetahui pengaruh konsentrasi asap cair kayu karet dan tempurung kelapaterhadap pengurangan polusi udara pada lump. Rancangan yang digunakan adalah acak kelompok, dengan delapan perlakuan, diulangempat kali. Parameter yang dianalisis pada asap cair meliputi pH, kandungan total phenol, kandungan total asam, dan komponensenyawa penyusun asap cair. Pada lump yang diamati adalah pH penggumpalan, uji organoleptik bau, kandungan NH3 dan kadar karetkering (KKK). Hasil penelitian menunjukkan asap cair kayu karet mempunyai kandungan total asam yang lebih tinggi daripada asapcair tempurung kelapa, tetapi mempunyai kandungan senyawa phenol yang lebih rendah daripada asap cair tempurung kelapa. Sebagaikoagulan, asap cair kayu karet 15% dan asap cair tempurung kelapa 10% menghasilkan mutu lump yang baik dengan gumpalansempurna tidak berbau busuk dan mempunyai KKK kategori mutu 1, yang memenuhi spesifikasi persyaratan mutu SNI 06-2047-2002. Kualitas lump yang dihasilkan lebih baik daripada penggunaan asam format (koagulan rekomendasi), terutama dalam menanganipolusi udara pada lump. Dengan demikian, asap cair kayu karet maupun asap cair tempurung kelapa merupakan koagulan ramahlingkungan.Kata Kunci: Kayu karet, tempurung kelapa, asap cair, lump, ramah lingkunganMost of rubber farmers in Indonesia make lumps on which some coagulants such as TSP fertilizer, alum and others are often used. These coagulant areacidic but they do not have antibacterial and antioxidant properties. As a result, the lumps yielded or produced were low in grade and foul smelling. Astudy was carried out in smallholder rubber plantations in West Java Province from May to November 2012. The purpose of this study was todetermine the effects of the concentration of rubber wood liquid smoke and coconut shells liquid smoke to reduce air pollution on the lumps. The designused a randomized block with eight treatments and four replicates. The parameters analyzed of the liquid smokes include pH, total phenol content,total acid content, and the components of compounds contained in the liquid smokes, while those of the lumps include pH clotting, odor organoleptictest, NH3 content and dry rubber content (DRC). The results showed that the rubber wood liquid smoke has a total acid content higher than thecoconut shell liquid smoke, but its phenol content is lower than that of coconut shell liquid smoke. As coagulants, the rubber wood liquid smoke of15% and coconut shell liquid smoke of 10% produce a good quality of lumps with perfect clots, does not produce bad smell and has DRC categoryquality 1. It meets the specifications of SNI 06-2047-2002 quality requirements. The use of rubber wood liquid smoke and coconut shell liquidsmoke in lump processing yields better quality than that of formic acid (coagulant recommended), especially in reducing of air pollution of lumps.Thus, rubber wood liquid smoke and coconut shell liquid smoke uses is environmentally friendly coagulant.

Abstract

Industrial cluster approach as an development strategy has been adopted nationally and continues to be strengthened in recent years. National Development Programme of 2003 mandated the cluster approach in the development of small and medium industries. Presidential Regulation No. 07 of 2005 states that national industrial development focused on strengthening and growth of the ten priority industrial clusters. The research is aimed to formulated strategy of cashew ind ustry cluster development in East Java. The data used are primary and secondary data, analyzed using Porter's Diamond. The research was conducted in S umenep, Sampang, and Bangkalan, using the survey in March - April 2011. Data analysis was conducted descriptively using Porter's Diamond Model. The results showed that the cashew industry cluster in East Java has not been going well as expected. The linkage between upstream and downstream industries are still weak, so is the quality of the products produced. Classical problems which have obstructed the development of the cashew industry in this region are crop productivity, product quality, regulatory and policy difficult to implement, still can not fully overcome. Determinant factor is the key to successful development of industrial clusters is the availability of raw cashew nuts, infrastructure, government policy, the interaction between players in the industry, the availability of supporting institutions, upstream and downstream industries, product demand conditions and the availability of foreign investors. Therefore, the handling can not be done spatially, must be supported by all sides and done in an integrated way. Cashew cluster industry development strategy needs to be done by improving government policy (regulation of markets for industrial products cashew, cashew export tax implementation, mandatory SNI nut products, improvement of the domestic market); strengthening the upstream and downstream industries (productivity and quality of cashew, increase the ability of the cashew processing industry); and optimization of the interaction between the core industry by supporting industry and other related institutions (farmers' cashew, cashew industry, food industry and beverage, industrial equipment & machinery, exporters, traders, government agencies, research and development institutes, associations industry, transportation and financial services/banking).

Abstract

Penelitian untuk mengetahui pengaruh media tumbuh dan interval penyemprotan fungisida terhadap viabilitas setek, pertumbuhan dan harga satuan benih lada dilakukan tahun 2010 di Kebun Percobaan Sukamulya, Sukabumi. Kegiatan terdiri dari dua tahap percobaan lapang dan satu tahap analisis ekonomi bibit lada. Percobaan pertama disusun berdasarkan rancangan acak kelompok dengan tiga ulangan dan jumlah setek setiap perlakuan sebanyak 50 setek benih lada satu ruas. Variabel pertumbuhan yang diamati adalah tinggi dan jumlah buku benih. Percobaan ke dua disusun berdasarkan rancangan acak kelompok dengan tiga ulangan dan jumlah benih setiap perlakuan sebanyak 50  benih lada. Pengamatan serangan penyakit dilakukan setiap bulan sampai umur benih empat bulan. Pengamatan pertumbuhan dilakukan sebanyak 20 benih yang ditentukan secara acak sederhana. Variabel pertumbuhan yang diamati adalah tinggi dan jumlah buku benih. Selanjutnya dilakukan analisis biaya pembenihan untuk mengetahui harga pokok benih lada. Hasil penelitian menunjukkan bahwa media tumbuh cocopit dan abu sekam baik sebagai media perkecambahan (viabilitas setek 100%), diikuti media campuran tanah dan pupuk kandang (viabilitas setek 94%), dan penyemprotan fungisida 9 hari sekali untuk menekan serangan penyakit. Hasil analisis ekonomi menunjukkan bahwa penggunaan teknologi media tumbuh + pupuk kandang dengan penyemprotan fungisida 9 hari sekali menghasilkan benih dengan harga pokok sebesar Rp 985,4, lebih murah (19,56%) dibandingkan penggunaan teknologi yang tidak tepat yang akan menghasilkan benih dengan harga pokok yang lebih mahal yaitu Rp 1.178,2.  Effects of Growing Media and Spraying Interval of Fungicide on Viability and Growth of Rooted Cuttings of Black Pepper and Its Cost PriceABSTRACT A research was established to assess the effects of growth medium and spraying interval of fungicide on viability and growth of rooted cuttings of black pepper as well as unit price of production of the cuttings. The research was carried out at Sukamulya, Sukabumi from January to December 2010. The research consists of two field experiments and an economic analysis of rooted-cutting production of the crop. The two of field experiments were:(1) Study of various growing media of rooted cuttings at nursery level. The objective of this study was to find out proper media giving the best viability of rooted cuttings; and (2) Study of spraying interval of fungicide to reduce risks of disease infestation on the cuttings, with its objective was to evaluate frequency of fungicide spraying being able to reduce risks of infestation. Growth variables observed were height of the cuttings and the number of cutting nodes, and disease incidences for 4 months. Infested cuttings were analyzed at a laboratorium to identify possible factors affecting the growth of cuttings. Whereas, an economic analysis was aimed to asses the effect of applied treatments which gave comparable benefits. The result showed that coco peat and rice husk ash were the best growth medium for cutting productions with viability of 100%, meanwhile the media of mixed soil and sheepdung resulted in lower viability (94%) than those of previous one. Fungicide spraying onto cutting nursery should be conducted at minimum 9 days interval to minimize the death of cuttings caused by disease attack. Based on the economic analysis, application of appropriate technologies would result more lower of spending unit price of cutting production of Rp.985.4 (19.56%) than inappropriate technologies (Rp.1,178.2).

Penelitian ini dilakukan untuk mengetahui pengaruh tingkat naungan dan media tanam terhadap pecah mata tunas dan pertumbuhan stum mata tidur bibit karet hasil okulasi hijau. Penelitian dilaksanakan di Kebun Percobaan (KP.) Pakuwon Balai Penelitian Tanaman Industri dan Penyegar, Sukabumi, pada bulan Januari-Desember 2013. Rancangan penelitian adalah petak terpisah dengan tiga ulangan. Sebagai petak utama adalah tingkat naungan (N) dengan 3 taraf, yaitu N0 = tanpa naungan, N1 = tingkat naungan 50%, dan N2 = 70%. Sebagai anak petak ialah media tanam (M) dengan 5 taraf, yaitu M0 = tanah tanpa pupuk, M1 = tanah + pupuk kotoran ayam (4:1), M2 = tanah + pupuk kotoran kambing (4:1), M3 = tanah + pupuk kotoran ayam + 2,5 g pupuk NPK, dan M4= tanah + pupuk kotoran kambing + 2,5 g pupuk NPK. Peubah yang diamati meliputi kecepatan pecah mata tunas dan pertumbuhan bibit. Hasil penelitian menunjukkan bahwa kondisi pembibitan karet tanpa naungan di KP. Pakuwon dengan intensitas cahaya 67.041,67 lux dan suhu udara 31,79 °C menghasilkan persentase pecah mata tunas dan pertumbuhan tinggi tunas hasil okulasi hijau tertinggi. Perlakuan media tanam dan interaksinya dengan tingkat naungan belum memperlihatkan pengaruh yang nyata terhadap persentase pecah mata tunas sampai umur 8 MST dan terhadap pertumbuhan tunas hasil okulasi sampai umur 16 MST.Kata kunci: Hevea brasiliensis, stum mata tidur, bibit, kotoran kambing, kotoran ayamThe success of green budding using budded stump of rubber seedling (Hevea brasiliensis) does not always give a good percentage of growth due to the influence of environmental factors and growing media. This study was carried out to determine the effect of shading levels and growing media that can enhance the growth of budded stump on rubber seedling derived from green budding. The experiment was conducted at Pakuwon Experimental Station (E.S.), Indonesian Industrial and Beverage Crops Research Institute, from January-October 2013. The study was designed as a split plot with three replications. The main plot is the level of shade with 3 levels: without shade (N1), 50% shade (N2) and 70% shade (N3). Meanwhile, subplot is growing media with 5 levels: soil without fertilizer (control) (P0), Soil + chicken manure (4: 1) (P1), soil + goat manure (4: 1) (P2), Soil + chicken manure + 2.5 g of NPK fertilizer (P3) and soil + goat manure + 2.5 g of NPK fertilizers (P4). The results showed that the condition of the rubber nursery without shade at Pakuwon E.S. with the light intensity of 67041.67 lux and temperature of 31.79 °C resulted the highest percentage of breaking buds and the growth of buds derived from green buddings. The treatment of growing media and its interaction with the shading levels does not show significant effect on the percentage of breaking buds until 8 weeks after planting (WAP) and the growth of buds until 16 WAP.

Abstract

A prolong dry periods could have a negative impact on growth and yield of cocoa. The objectives of this study were to evaluate the tolerance levels of 35 cocoa genotypes to dry periods. The study was conducted at the Pakuwon Experimental Station, Indonesian Industrial and Beverages Crops Research Institute, Sukabumi, West Java; 450 m above sea level; Latosol soil type; and B type of climate; started from August 2014 until October 2015. Thirty five cacao genotypes consisted of two released variety  (i.e Sulawesi 1 and SCA 6) and 33 other genotypes were used in this research.  The cacao plants were three-years old, cultivated at a 3 x 3 m spacing distance under the 26 years old Salak Dwarf coconut trees.  Ten plant samples were determined randomly and the fruits were harvested in February 2015 (wet period) and October 2015 (dry period). A bulk of 10–30 pods per genotype were randomly selected for each harvest periods. The variable observed were fresh weigth per pod,  number of beans per pod, fresh and dry weight of beans per pod, and fresh weight of pod husks + pulps per pod. The tolerance level to dry periods was determined base on the dry weight of bean/pod.  The result showed that a continueous six months dry periods prior to harvesting significantly reduced yield components from 4.92%-42.54%.  Based on the dry weight of beans per pod, three genotypes, namely KW 162, KW 165, and KW 215, were classified as tolerant, while the other were moderately tolerant and susceptible to drought. The result implies the important of further research to obtain superior cocoa clones resistance to drought.
