Abstract

The sandalwood tree (Santalum album Linn.) is an important tree species as well as a primadonna for the people of East Nusa Tenggara (NTT). It has high economic value for its aromatic wood and essential oil content that have a very distinctive aroma used to make various products such as handicrafts, woodcarvings, incense, and oil for the perfume and cosmetics industry. Sandalwood is a semi parasite plant that part of its life phase requires a host plant to get the nutrients and water. There are many types of host plants that have been used, among others, Casuarina equisetifolia, Acacia mangium, Terminalia microcarpa, Sesbania grandiflora, Alternanthera sp and Capsicum annum. In this research will be tested to try sandalwood planted with Cymbopogon nardus host plants, in terms of economics can provide benefits.Arbuscular mycorrhizal fungi (AMF) is a group of fungi from glomeromycota phylum that can symbiosis mutualism with root system of high level plant. The working principle of the mycorrhiza is to infect the root system of the host plant, producing intensive hyphae tissue so that the plant containing mycorrhiza will be able to increase the capacity in nutrient uptake. The utilization of host plants Alternanthera sp, Capsicum annum, and its application with AMF is the best solution to overcome the problem of developing sandalwood in TTU on the nursery. The purpose of this study was to analyze the effectiveness of AMF and utilization of the atsiri host plant to increase the growth of sandalwood seedlings in TTU. This study was designed using a complete random method (RAL) in split plot design. If the treatment has a significant effect then followed by Duncan Multiple Range Test (DMRT). Parameters observed were height (cm), number of leaf, diameter of sandalwood (mm), dry weight of root, seed quality index, ratio of root buds, and haustorium observation of Sandalwood, and also number of spore, root colonization and AMF dependency of Sandalwood.The results showed that the treatment of AMF with Capsicum annum host plant was 19.8 of high, number of leaf 18.9 on FMA treatment with host plant Capsicum annum, diameter of stem 2.24 mm on Alternanthera sp host treatments without AMF and 1.83 mm at AMF treatment with host plant Capsicum annum, dry weight of buds 2.00g on AMF treatment with Capsicum annum host plant, dry weight of roots AMF (M1) with alternanthera sp 0.70 g, root buds ratio of AMF with host plant alternanthera sp 4.05, seed quality index AMF with Alternanthera sp 4.16 and 82 % of root colonization on AMF with host plant Capsicum annum.Keywords: Santalum album Linn., AMF, host plant.

Abstract

Pertambangan batubara terbuka menyebabkan degradasi lahan, sehingga perlu upaya rehabilitasi lahan melalui program revegetasi. Penelitian dilakukan di areal PT. Berau Coal  pada site Binungan, Lati dan Sambarata, Kabupaten Berau, Kalimantan Timur, Indonesia. Penelitian menggunakan rancangan acak lengkap ber-blok dengan umur revegetasi sebagai perlakuan, tiga kali ulangan dan tiga site sebagai blok. Pemilihan lokasi menggunakan metode purposif sampling yaitu pengambilan sampel yang didasarkan pada pertimbangan pada umur pengolahan lahan revegetasi, meliputi S1 : area hutan sebelum ditambang (rona awal), S2 : revegetasi awal, umur tanaman  < 1 tahun, S3 : revegetasi menengah, umur tanaman 3 tahun, dan S4: revegetasi lanjut, umur tanaman  > 5 tahun. Pengambilan sampel tanah pada  kedalaman 0–20 dan 20-40 cm pada setiap perlakuan di ketiga lokasi, selanjutnya dianalisis sifat fisik dan kimianya. Tanah Typic Hapludult pada lahan hutan sebelum ditambang batubara secara terbuka (S1,  rona awal) mempunyai kadar C-organik (1,87 %), N-total (0,14 %), P-tersedia (31,40 ppm), K-tertukar (0,11 me/100g), pH (3,98), KTK (10,72 me/100g) dan kejenuhan basa (17 %). Penambangan terbuka batubara telah menyebabkan lapisan bawah dan  permukaan tanah menjadi terbongkar dan terjadi penurunan kualitas tanah yang sangat drastis. Penimbunan lahan dengan media tanah permukaan sebelumnya, telah cukup  mampu memperbaiki sifat-sifat tanah tertambang namun belum sesuai sebagai media pertumbuhan, serta sangat rentan terhadap degradasi lahan lebih lanjut. Revegetasi menggunakan tanaman pionir, cepat tumbuh dan adaptif seperti Sengon, Akasia, Sungkai, Melina, Angsana, Jarak serta Legume Cover Crop (LCC) pada area bekas tambang  batubara memberikan pengaruh yang  nyata terhadap peningkatan kandungan C-organik, N-total dan  pH tanah. Revegetasi menggunakan spesies cepat tumbuh setelah berumur 5 tahun telah mengembalikan bahkan memperbaiki sifat kimia tanah dibanding dengan kondisi pada hutan tropika basah sebelum dilakukan penambangan terbuka.

Abstract

Pupuk organik perlu didekomposisi oleh mikroba dan memerlukan lingkungan yang sesuai agar cepat matang sempurna dan tidak memberikan dampak negatif pada aspek sosial, estetika maupun kesehatan pada makluk hidup dan lingkungan. Dekomposisi bahan pupuk organik dilakukan dengan menggunakan kotoran sapi, dengan 2 perlakuan mikroba (tanpa dan dengan mikroba starter) dan 3 variasi waktu, yaitu 0, 6 dan 24 jam setelah diberi mikroba starter. Analisis meliputi  uji fisik bahan pupuk yang meliputi pH, warna, aroma, lengas, dan DHL,  uji mikroba patogen (Eschericia. coli dan Salmonella) pada pupuk, pengujian kandungan hara pupuk total (C, N, P, K, Ca, Mg, Na, S, Cd, Cr, B, Fe, Cu, Zn)  dan Ntersedia (NH4 dan NO3),  serta analisis emisi gas amonia (NH3), oksigen (O2), karbon monoksida (CO), karbon dioksida (CO2), metana (CH4), NOx, NO, dan SO2. Mikroba starter mengandung mikrobia dan unsur hara yang sangat diperlukan dalam proses dekomposisi bahan organik. Pupuk kandang sapi setelah aplikasi  mikroba starter masih mengandung E. coli dan Salmonella sp. yang cenderung menurun seiring dengan lama waktu inkubasi. Terjadi dinamika kandungan unsur-unsur hara seperti P, K, Mg, Fe dan Cu serta logam berat Cr selama proses inkubasi baik pada pupuk kandang ayam maupun sapi. Dengan perlakuan mikroba starter, bagian senyawa sulfur dari bahan organik banyak yang terombak menjadi gas SO2 yang relatif tidak berbau, dan sebaliknya H2S serta senyawa reduktif sulfida lainnya menjadi terhambat pembentukannya. Perombakan dengan  mikroba starter sebaiknya diupayakan dalam suasana aerobik atau dengan suasana lembab tetapi tidak sampai anaerobik sehingga kehadiran senyawa H2S dan senyawa sulfur reduktif lainnya dapat dikurangi atau tidak terbentuk. Hasil penelitian ini menunjukkkan pentingnya penggunaan mikroba starter optimal dan benar untuk memperbaiki kandungan nutrisi dan kualitas pupuk kandang.

Abstract

Eruption of Merapi volcano caused accumulation of lahar materials that led to extensive land degradation.  This research was to study the population of pioneer plants and their correlation with endomycorrhiza population at  different land qualities after Merapi eruption.  Samples of soil, pioneer plants, and endomycorrhiza were collected from Merapi volcano, 1 year after eruption, using stratified sampling method based on plant densities, with the following categories: dense vegetation, moderately dense vegetation, sparse vegetation, and control (bare land), with 3 replications for each category.  Pioneer plants and endomycorrhiza were identified. Plant biomass, soil pH, total-C,-N, and exchangeable-K, -Ca, -Mg, -Fe were analyzed. The abundance of pioneer plants and their interaction with mycorrhiza was strongly correlated with depth of eruption material, quantity of sandy texture, soil pH, total-C and total-N, exchangeable-K, exchangeable-Ca, exchangeable-Mg, and exchangeable-Fe.  Among the 12 identified pioneer plants, only Acacia villosa, Fiurena ciliaris, and Bidens pilosa were recommended as plant-remediator to improve soil chemical, physical and biological properties. Among the 3 genera of endomycorrhiza (Acaulospora, Gigaspora, Glomus), only Acaulospora was recommended to be a biological agent to rehabilitate sandy soil area.  This research indicated that adaptive pioneer plants and endomycorrhiza  were likely to be suitable for biological agents to stimulate recovery of degraded land through improvement of physical, chemical, and biological properties, that will stimulate plant growth and biodiversity.

Abstract

As one of the international covenant that had been ratified by Indonesia through UU No. 7 Tahun 1984, CEDAW had been made several consequences like abortion legalization and easy access of contraception. One thing must be noticed that CEDAW didn’t mention marriage as a must, as we can review from ICPD’s definition about reproductive health in women. ICPD was a dynamic response from CEDAW. As a convention emerged from West’s worldview, Indonesia as an adoption country, must doing strict selection because CEDAW can be mean of infiltration West’s worldview. The formulation of this research are how the concept on reproductive health women in CEDAW and how Islam’s critics toward the concept of reproductive health women in CEDAW. The aim of this research is to know the concept of reproductive health in women and how Islam critics about that concept. The method of this research was library research, with specifically analysis documents. The researcher using content analysis to analysis the content of the documents. Overall, researcher use deductive method for analysis. The findings from concluding comments’ documents, CEDAW’s committee feedback about application CEDAW in Indonesia, is feminism value. The point is women have fully freedom to decide all the problems in her reproductive health without intervention by her husband, her family, country or religion. Islam has point of critics start from difference on worldview. Islam as worldview has its paradigm towards several concepts, like concept of God, concept of divine, concept of prophet, etc.

Abstract

We study the localization properties of non-Abelian field in the representation of SU(2) group both in the modified Randall-Sundrum (MRS) and in the original Randall-Sundrum (RS) models. We investigate the conditions of localization for each model. We derive the equation of motion for the field. We solve the field equation corresponding to the extra dimension and analyze the localization properties of the field on the brane. We obtain that the MRS model has different field localization properties compared to the RS model. We find that non-Abelian field is localizable on the brane of the MRS model with specific conditions but the field is not localizable on the brane of the RS model.
