Abstract

Arrowroot (Maranta arundinacea L.) is usually propagated through young tillers or rhizome cuttings. A glass house and field tials were carried out at the Cimanggu Expeimental Insulation of the Research Institute for Spice and Medicinal Crops (RISMC), to assess 0k efect of rhizome patition and number of nodes of each parts on the viability of rhizomes, growth, productivity and starch content of arrowroot A clone of arrowroot (No. 17) collected from RISMC was used. One, two, three or four nodes of rhizomes cut at the base, middle or tip were used. A preliminary study was conducted in glass house from August to September 1999, where 40 samples of rhizomes were tested for their viability. Further study was conducted in the field from October 1999 to April 2000, to assess the growth, productivity and starch content of the rhizome from each treatment. The ield experiment was designed as a randomized block, arranged factorially in three replicates. The first factor was rhizome part (base, middle or tip) snd the second one was number of nodes (one, two, three or four nodes). Results showed that the highest percentage of plant growth, and seedling vigor of one month old were obtained from Uic four nodes tip rhizome cutting. At 6.5 month after planting the highest significant yield of resh rhizome was obtained from both base and middle parts rhizome cutting (324.04 and 326.46 g/hill), while the tip curling only produced 240.0 g/hill. The highest starch yield was obtained from the treatments of both the base and middle parts rhizome cutting i.e. 52.51 and 61.25 g/hill, while the tip cutting produced 47.19 g/hill. There was no interaction efect between the irst and the second factors on fresh rhizome yield. Highest signiicant fresh rhizome yield can also be obtained by using more than one node (320.96 - 337.69 g/hill), while a node cuting gave 198.65 g/hill only. Using base and middle rhizome cutting with 3 nodes gave the effective and eficient result, since it gave higher yield of the resh rhizome starch (70.38 and 72.41 g/hill).

Abstract

Design of axialflow thresherfor pepperThe pepper threshing practice has been carried out using traditional method in which the pepper berries are usually trampled. This method is neither efficient nor higienic, and it also causes high losses of the berries. To overcome those problems, an experiment was carried out to make an axial flow thresher. The experiment was conducted at Research Institute for Spice and Medicinal Crops from April to December 1999. The experiment consisted of three steps, namely designing, constructing and testing. The objective of testing was to determine the optimum operation condition of the thresher. The testing was designed as a completely randomized complete design with three replications. The raw material for testing was pepper berries (Lampung Daun Lebar variety) of 8 - 9 month old. The result showed that the optimum condition for threshing process was 300 rpm cylinder rotation, with the spike separation process using 7.5° sieve angle. The performance of pepper thresher on that condition was : threshing eficiency 98.55%, spikes separation eficiency 89.22%, berries on spikes outlet 5.20% and berries damage 6.30%. The capacity of thresher was 260.56 kg raw material/hour. The operational cost was Rp 27.28/kg raw material, lower than that of the traditional threshing method (Rp 50/kg raw material).

Abstract

Effect of dilution of basic medium on ginger growth during conservation in vitroBasic medium dilution could affect the growth of the culture. The effect of basic medium dilution was evaluated at the laboratory of Research Institute for Spices and Medicinal Crops from October 1998 to June 1999. Sterile shoots of ginger were used as ex plants. Basic medium dilution from 3/4 MS, 1/2 MS, 1/4 MS and MS normal (control) were used as treatments. The media were enriched with BA 3 mg/1 and Sucrose 6%. The treatments wee arranged in a completely randomized design with three eplications. Results showed that all the dilution treatments inhibited the grow of the culture during live months of conservation period, especially on 1/4 MS + BA 3 mg/1 + Sucrose 6% . On the media, the number of shoots wee 3.55. Based on cultue performance the best medium for conservation was 1/2 MS + BA 3 mg/1 + Sucrose 6%. All of the culture was able to growth in regeneration media after they were conserved for ive months. Results of this experiment could be applied in reducing sub-cultue frequency to a new media and maintain the culture stability. e

Abstract

An alternative to produce healthy planting materials of ginger is through tissue cultue. However, the information on productivity and cultural practices or such mateial is still limited. Among the cultural aspects, fertilizer application and plant spacing mostly afect plant growth and yield. The objective of this study, was o evaluate the effect of fertilizer application and plant spacing on the growth and yield of rhizome. Planting materials (tissue culture and conventionally derived rhizomes) wee espectively planted in two plant spacings (60 cm x 40 cm and 40 cm x 30 cm) and applied with two levels of ertilizers (with and without fertilizer). The fertilizers applied were 40 tons stable manure and urea, TSP, and KCI wee 400 kg/ha. The expeiment was conducted in the Sukamulya Expeimental Station (Sukabumi)) rom August 1994 to  December 1995 in a split-split plot design in four replicates. Die main plot was ertilizer application, the sub plot was plant spacing and the sub-sub plot was planting material. The parameters used for evaluating the response of the plants to the treatments wee growth components (plant height stem circumeence, number of tillers and leaf size), and yield components (weight and size of rhizome). Results revealed that plants rom tissue culture generally showed the lower growth performances with lower yield and size of rhizomes, except in the number of tillers. The application of urea, TSP, and KCI at a respective rate of 400 kg/ha significantly increased plant height (rom 49 o 60 cm), stem circumerence (rom 2.2 o 2.6 cm) and weight of rhizome/clump (rom 206 o 379 g). Plant spacing did not affect any parameter observed. Interaction efect was shown between the source of planting materials and fertilizer application on the number of tillers and the thickness of rhizomes. For the plants rom tissue cultue ertilizer application significantly increase the number of tillers (rom 18 o 30 tillers/clump) and for those rom conventional rhizome the treatment did not afect the parameter. On the other hand, for the plants rom conventional rhizome ertilizer application improved the thickness of rhizome (rom 2.51 o 3.17 cm) while for those rom tissue cultue the teatment did not give any efect on the parameter. The thickness of rhizome was also afected by the interaction between fertilizer application and plant spacing. For the plant spacing of 40 cm x 30 cm, ertilizer application inceased the thickness of rhizome (from 1.68 to 2.11), while those of 60 cm x 40 cm, the teatment did not afected the parameter.

Abstract

Design of the hand-powered thresher for black pepper processingProcessing of pepper berries (Piper nigrum L.) into black pepper needs thresing to remove the beries from the stalks prior to sundrying. Until now, the threshing practice is caried out by traditional method in which the pepper beries are trampled. This method is not eficient nor hygienic and it also causes high losses of the berries. To overcome those problems, a hand-powered thesher has been designed. The experiment consisted of thee steps, namely designing, constructing and testing. The threshing mechanism was based on impact and friction, whereas the separation of the berries from the stalks was based on the difference in shape and dimension. The dimension of the pepper thesher is 900 mm length, 450 mm width, and I 200 mm height. The test results showed that the hand-powered thresher have a good performance. The capacity of the thesher is 100 kg of pepper berries (berries + stalks) per hour. The operational cost is Rp 30.02 per kg of pepper beries, cheaper than that of the traditional theshing method (Rp 50/kg). This equipment is easy to apply in rural area, and can covee the theshing operation of 2.1 hectare of pepper plantation during harvesting periode.

Abstract

Lampung Province is one of nutmeg-producing region in Sumatra. Today nutmeg is one of the region's export commodities. The quality is an important factor in global nutmeg trade. The aim of this study was to assess nutmeg development prospect by analyzing the land characteristics and the quality of nutmeg. The study utilized a survey method to characterize the land and performance of smallholder nutmeg plantations, to communicate with farmers and to sample some nutmeg seeds for quality analysis. The survey was carried out in four subdistricts of the main nutmeg producing areas in Tanggamus Regency, namely Kota Agung-Timur, Gisting, Semaka, and Air-Naningan, in each area, 2-3 smallholder nutmeg plantations were assessed. The areas suitable for nutmeg development are Kota Agung-Timur, Gisting, and Semaka. The main supporting factor is water availability throughout the year, whereas the limiting factor are air humidity >75%, low organic C and CEC ≤16 cmol (+)/kg of soil, and erosion hazard due to a slope of >15%. Nutmeg productivity has potentials to be improved through technological innovation as current nutmeg cultivation is still conventional and does not use superior seeds, fertilizer and postharvest technology. On the other hand, the nutmeg seeds qualities have met SNI standards such as specific gravity, refractive index, optical rotation, soluble in alcohol, and chemical properties such as myristicin, α-pinene, sabinene, and safrole. Methyl eugenol is below the threshold of the European Pharmacopoeia standard and the α-pinene is better than nutmeg essential oil of produced from other regions.Keywords: nutmeg, land, physical and chemical qualities of nutmeg, Tanggamus of Lampung Province AbstrakProvinsi Lampung adalah salah satu daerah penghasil pala di pulau Sumatera. Saat ini pala merupakan salah satu komoditas ekspor daerah tersebut. Mutu merupakan faktor penting dalam perdagangan pala global. Tujuan penelitian adalah mengkaji prospek pengembangan tanaman pala berdasarkan analisis karakteristik lahan dan mutu hasil pala di Provinsi Lampung. Penelitian menggunakan metode survei untuk mengkarak-terisasi lahan dan keragaan tanaman pala, serta melakukan tanya jawab dengan petani dan mengumpulkan biji pala untuk bahan analisis mutu. Survei dilaksanakan di empat daerah penghasil pala utama di Kabupaten Tanggamus, yaitu Kecamatan Kota Agung Timur, Gisting, Semaka dan Air Naningan. Di masing-masing kecamatan dikunjungi 2 - 3 kebun pala rakyat. Daerah yang cukup sesuai untuk pengembangan pala adalah Kota Agung Timur, Gisting, dan Semaka (Tanggamus bagian Barat). Faktor pendukung utama pertumbuhan dan produksi pala di daerah ini ialah air tersedia sepanjang tahun, sedangkan faktor pembatas adalah kelembapan udara >75%, kandungan C-organik tanah rendah, dan KTK tanah 16 cmol (+)/kg. Faktor pembatas lainnya adalah bahaya erosi tinggi yang disebabkan oleh kemiringan lahan >15%. Produksi dan mutu pala berpotensi ditingkatkan melalui inovasi teknologi karena budidaya pala masih bersifat konvensional, tanpa bibit unggul, pupuk dan teknologi pascapanen. Potensi lain adalah sifat fisik seperti berat jenis (BJ), indeks bias, putaran optik, kelarutan dalam alkohol, dan sifat kimia seperti kandungan miristisin, -pinen, sabinen, serta safrol biji pala Lampung telah memenuhi SNI. Metil eugenol sebagai senyawa karsinogenik terukur di bawah ambang batas ketetapan European Pharmacopoeia, dan kandungan -pinen terindikasi lebih baik dibanding di dalam minyak atsiri biji pala daerah lainnya di Indonesia.Kata kunci: pala, lahan, mutu fisik dan kimia pala, Tanggamus Provinsi Lampung

Abstract

Coconut improvement programs require knowledge of the effect of morphological characters on the coconut yield. The study aimed to determine the effects of fourteen morphological characters on the production of coconut meat character on Kampung Laut and Pengabuan tall coconut. This study was conducted in Kampung Laut and Pengabuan Villages, Jambi Province. Correlation analysis among 15 characters of vegetative, generative, and fruit components used the Walpole formula (1992). Fourteen characters affecting meat production were analyzed by using Path analysis of Singh and Chaudary formula following the R i386 3.5.2 software package in the Agricole package. Correlation analysis resulted in the characters of the number of leaves, number of bunches, number of fruits, polar circumference of fruit, weight of unhusked fruit, equatorial circumference of nut, and weight of endosperm correlated with the production of endosperm, on Kampung Laut tall coconut, while Pengabuan tall coconut have number of fruits, equatorial circumference of nut, and weight of endosperm. The results of path analysis showed that the characters of the number of bunches, number of fruits, and weight of endosperm had a significant direct effect on the production of endosperm on the Kampung Laut tall coconut. While on the Pengabuan tall coconut, only the fruits number and endosperm weight affected the endosperm production. The study indicates that the number of bunches, number of fruits, and weight of endosperm can be used as selection criteria to increase the production of the endosperm of the Kampung Laut and Pangabuan tall coconut.Keywords:   Morphological characters, correlation, fruit components, selection AbstrakProgram perbaikan tanaman kelapa membutuhkan pengetahuan tentang pengaruh karakter morfologi terhadap hasil.

Abstract

The experiment was conducted to study the effect of temperature and host size on the growth and development of Trichogramma sp., a species of parasitoid which attacks Cricula trfenestrata s eggs. The experiment was carried oul in the Pesl laboratory, Dalillro, Bogor. with relative humidity ranged between 60-80%. temperature ranged.between 23-25°C, 26-28°C, and 29-3 l"C. with two kinds of different egg size (big and small). This research was conducted from March lo Sepeniber 2000, to optimize the production (generation) of Trichogramma sp. in the Laboratory. The resuts showed that some of Ihe biological index of Trichogramma sp., changed when it was cultivated in different temperature and host size. Temperature influenced longivity of parasitoid while host size influenced almost all of Ihe biological index. Although it was hardly measured, however the temperature and host size seemed to have mutual support in Influencing 7}"fcAogrximnta biological index. In low temperature, the development of parasitoid was longer than that in high temperature, while parasitoid behaviour in ovipositing was influenced by egg size. On Ihe big size host, parasitoid tended ovipositing all al once, while thai on small host ovipositing was done one by one. Ihe average of Trichogramma generation on big host was 42.1 ± 17.1 with sex ratio 1 8.8 I , while thai on small host was 73.3 ± 1 3.2 with sex ratio 6.71 I , where female was plcnticr than male. By using Birch methods, it was showed that intrinsic growth rate (r„) and net reproductive rale (Ro) on big size host were lower compared with small size host while generation lime (T) on big host was longer than small host. Ro values were significantly different belween the two hosts. The result of this experiment also showed that on both host sizes, optimum value of T, Ro and rm was achieved on 26-28°C. These results arc expected to guide parasiloid breeders lo decide the temperature and host size in mass cultivating Trichogramma sp. in laboratory. While for ield application, tempeature and hosl range arc Ihe factors should be considered.
