Kebutuhan gandum yang terus meningkat setiap tahun memaksa usaha penanaman gandum di Indonesia. Dengan mengembangkan gandum yang mampu beradaptasi di lahan cekaman abiotik, berupa suhu tinggi dan lahan kering, dapat menjadi jalan keluar dari keterbatasan lahan. Tujuan: mengetahui dinamika pertumbuhan dan hasil panen beberapa genotipe gandum yang diadaptasikan di dataran rendah tropis dan melakukan seleksi genotipe hasil adaptasi calon varietas berdasar penampilan fenotipe. Penelitian dengan penanaman 10 genotipe gandum F2 hasil adaptasi tahun sebelumnya, di Desa Telogoweru, Guntur, Demak  pada bulan Juli hingga Oktober 2013. Penelitian selanjutnya adalah melakukan seleksi berdasarkan penampilan terbaik dengan penanaman kembali hasil panen F2. Kesimpulan: terjadi penurunan nilai tinggi tanaman dalam proses adaptasi tetua, F1 maupun F2, dan pada karakter jumlah anakan terlihat adanya peningkatan dari proses adaptasi F2. Potensi hasil menunjukkan penurunan berat 1000 butir dan jumlah biji per malai dalam proses adaptasi tetua, F1 dan F2, tetapi untuk hasil biji per hektar, genotipe LAJ3302, ALTAR, SELAYAR, dan OASIS mampu menunjukkan peningkatan hasil. Proses seleksi menunjukkan bahwa genotipe LAJ3302, ALTAR, SELAYAR, OASIS, BASRIBEY, dan HP1744 merupakan genotipe yang dapat dijadikan calon varietas tahan cekaman suhu tinggi dan kekeringan

Abstract

The demand for palm sugar is increasing since people prefer natural ingredients. Natural and organic food ingredients have the reputation of being healthier and safer than synthetic ingredients. This study will discuss one particular ingredient namely palm sugar which is known as a natural sweetener. Developed countries have started to import palm sugar as a natural sweetener from developing countries. The production of palm sugar in developing countries has an important benefit in the craftsman household economy. However, current production of palm sugar does not meet the increasing demand, which is caused mainly by the lack of farmers, palm sugar craftsmen’s inadequate knowledge of palm sugar production, and poor incorporation of technology both in the cultivation of palm tree and the production process of palm sugar. This literature review study aims to understand the continuity of palm sugar production within the following framework which consists of four steps: (1) identifying current situation, (2) identifying the problems, (3) presenting the resolution, (4) proposing programs and strategies. Based on this framework a few programs and strategies are generated to maintain the continuity of palm sugar production, they are: (1) Palm trees domestication, (2) research and development center for Indonesian palm sugar, and (3) ensuring a good collaboration among the stake holders involved.

Abstract

The characteristics of seed coat delay the germination of sugar palm seeds. A research was carried out to investigate the permeability of sugar palm seeds and accelerate the germination. The research consists of four experiments with purposes: 1. to investigate the distribution of water content of sugar palm seed (RCBD Factorial between part of seed : whole seed, seed coat, endosperm and embryo under three conditions: control; soaking in water and germinate, 5 replications); 2. to investigate seed permeability (RCD, 6 soaking periods, 4 replications); 3. to investigate the content of lignin and tannin in seed (RCD, 8 seed ages, 4 replications); 4. to accelerate seed germination (RCBD, 6 treatments of scarification, 4 replication).  The results showed that the permeability of sugar palm seeds to water absorption declined with seed maturity because of the increasing in lignin and tannin content. Seed germination can be accelerated with scalding on the operculum site to increase water absorption.   Key words: Sugar palm, seeds, permeability, germination

Abstract

The research of the effects of retardant and terminal bud pinching on the performance of potted chrysanthemum was conducted using the Randomized Block Design, consist of seven treatments and four replications. The treatments were P1) control without retardant and bud pinching; P2) Retardant at transplanting into pots; P3) Retardant at one week after transplanting; P4) Retardant at two weeks after transplanting; P5) Pinching at the time of transplanting; P6) Pinching at one week after transplanting; P7) Pinching at two weeks after transplanting. Experimental data were analyzed using ANOVA and the analysis of the differences among treatments used Honest Significant Different (HSD) with α=5%. The results showed that retardant increased the chlorophyl of leaf, reduced the height of plant and diameter of shoot, reduced the number and diameter of flowers. Pinching decreased the height of shoot, increase the number of flowers. Retardant and pinching treatment did not cause the anthesis simultaneously. The performance of chrysanthemum pots on retardant treatment is more ideal than control and terminal bud pinching treatment. Keywords: chrysanthemum, flowering, growth, paclobutrazol, pinching
