Abstract

Plants show different physiological responses to light intensities. Study on optimum light intensities for different plants is important, especially for commercial plant commodities, such as industrial plantation plants. This research aims to study the influence of shading and fertilization treatments on plant growth and the activity of some physiological process of four industrial trees namely Cacao (Theobroma cacao), Coffee (Coffea arabica ),  Rubber (Hevea brasiliensis) dan  Clove (Syzygium aromaticum). This research was conducted at Cibinong Science Center LIPI. Two treatment factors applied were three levels of shading : 0%, 55%, 75% and three levels of N ferlitizer: 0 g/plant, 5 g/plant and 10 g/plant arranged in Randomized Block Design with five replicates. Result of experiment revealed that all plant species showed the best growth performance and optimum physiological activities under 55% of shade level in combination with 10 g of N fertilization. The highest CO2 was 13.07 µmolm-2s-1  (55%  shad). The highest values of transpiration and stomatal conductance were 7.56 molm-2s-1 dan 0.73 molm-2s-1 (55% shade). The highest carbohydrate content was 22.49% (under 0% shade) and the lowest was 12.74% (under 75% shade). Keywords: Physiological activity, growth, shading, fertilization

Abstract

Research has been carried out through the utilization of organic fertilizer to improve the productivity of local maizecultivar originated from South Sulawesi. The study was conducted at the research station of Research Center for Biology,Cibinong Science Center. Corn seed were planted in polybag containing mixture of soil and compost, 6 and 2kg, respectively. The research were carried out by Randomized Complete Block Design arranged in factorial experimentwith four replications. The first factors are three types of local maize namely A: rice corn (pulut beras, BataraKoasa), B: waxy corn (pulut biji, Batara Kamu), C: pulut hibrida (hybrid cultivar). The second factors are 14 combinationtreatment as a mixture of LIPI organic fertilizer (Beyonic-StarTmik, Bio121, EM-121 and MegaRhizo) andanorganic NPK fertilizer. The variables observed were plant growth and production. The results showed that thehybrid cultivar had higher total corn yield productivity compared to the local one, although hybrid cultivar hassmaller plant biomass. Waxy corn (B) accession showed the weight, length and diameter of cob, and also the weightof 100 grains larger than rice corn (A). Fertilization treatments significantly affect the corn-cob productivity which isincludes the weight, length, and diameter units. Fertilization treatments such as EM-121 + (½ dose of NPK), BIO-121 + (½ dose of NPK), and Beyonic + (¼ dose of NPK) showed a good effect on plant, and it was not significantlydifferent with 100% NPK (full doses of NPK). The three corn cultivar showed different responses to fertilizationtreatments.Keywords: local corn, biofertilizer, growth, production

Abstract

Jali (Coix lacryma–jobi L.) merupakan serealia minor yang sudah dikenal dan dikonsumsi masyarakat lokal Indonesia. Tanaman ini sudah jarang dibudidayakan petani bahkan dalam skala kecil sekalipun. Padahal tepung jali bergizi tinggi dan dapat digunakan sebagai pengganti terigu dalam pembuatan berbagai jenis kuliner. Telah dilakukan berbagai penelitian meliputi aspek budidaya, panen dan pasca panen jali untuk pembuatan aneka kuliner.  Tujuan yang ingin dicapai adalah jali menarik untuk dibudidayakan dan dimanfaatkan secara optimal untuk pengembangan usaha industri rumah tangga skala kecil dan menengah  berbasis sumberdaya lokal. Hasil penelitian menunjukkan budidaya jali dapat dilakukan di tempat terbuka maupun agak ternaungi (maksimal 50% naungan). Dalam budidayanya, pemupukan diperlukan untuk mendapatkan hasil optimal. Kuliner berupa kue kering dengan bahan dasar 100% tepung jali menunjukkan citarasa yang khas, renyah, agak padat dengan tekstur butiran-butiran lembut khas tepung jali. Apabila dicampur dengan pati taka, kue kering menjadi renyah, lebih remah, meski masih terasa sedikit butiran-butiran lembut khas jali. Kue kering dari tepung jali + tepung mocaf mempunyai cita rasa renyah, tidak terlalu remah daripada jali +taka dan masih terasa sedikit berpasir khas tepung jali dengan butiran-butiran pasir yang lebih lembut, terasa sedikit agak asam, beraroma bau khas fermentasi. Rasa kue kering jali enak dan khas.  Pengolahan jali ini diharapkan dapat diterapkan langsung di masyarakat dan dapat dikembangkan sebagai industri rumahan. Dengan pembuatan kue kering dari bahan tepung jali, pati taka dan mocaf ini, diharapkan menjadi daya tarik untuk menciptakan variasi pangan yang berkualitas, sehingga diminati masyarakat dan dapat meningkatkan penghasilan masyarakat. Kata Kunci: Jali,  budidaya, gizi, kue kering, industri rumah tangga ABSTRACTJali (Coix lacryma-jobi L.) is a minor cereal that known and consumed by local Indonesian people. The cultivation was rare even on a small scale. Meanwhile, the high nutritious jali flour can be used as a substitute for wheat flour in the producing  various types of culinary such as cookies. Many researchs have been done to find out the cultivation, harvest and post-harvest of jali in order to re-popularized jali for development of small and medium home industry based on local germ plasm resources. The results showed that jali can be cultivated both on open or on maximum 50% shading area. For cultivation, the fertilization treatment is needed to reach an optimal grain production. The cookies produced based on 100% jali flour showed a special taste, crunchy, and slightly sandyness (as a typical of jali flour). When mixtured with taka starch, the cookies become crunchy, more crumbly, with little bit sandyness. Cookies made from jali + mocaf flour have a crunchy taste, not too crumbly than jali + taka and still taste a little gritty, sandyness, a little sour, and smell of fermentation. The jali cookies is delicious with special taste. It is hoped that cookies produced based on jali, tacca and mocaf flour can be utilized by the local community to developed their home industry for special, delicious and high nutritious culinary to increase people's income. Key words: Jali,  cultivation, nutrition, cookies,  home industry.
