Abstract

ABSTRACTHypocotyl and cotyledon are potentially used as effective morphological markers since they can be detected earlier. Information on inheritance of tomato hypocotyl and cotyledon was not available. The aims of this research was to study the inheritance of qualitative and quantitative characters of tomato hypocotyl and cotyledon. This research used six population, P1 green hypocotyl (IPB T64), P2 purple hypocotyl (IPB T3), F1, F1R, BCP1, BCP2, and F2. Analysis of qualitative characters used Mendelian and gene action of quantitative characters used joint scaling test. The results of Mendelian indicated that the character of hypocotyl color was controlled by two genes of dominant-recessive epistasis. The gene controlling purple color was dominant to the green color gene. Based on the F2 distribution test, hypocotyl length, cotyledon length and width were controlled by polygenes. There was no influence of maternal effect. The results of the joint scaling test showed gene action of hypocotyl length was controlled by additive gene with influence of additive-dominant epistasis. Length and width of the cotyledon were controlled by additive gene and influence of duplicate epistasis effect. All characters had high level of broad sense heritability and medium level of narrow sense heritability.Keywords: cotyledone, gene action, heritability, hypocotyle, morphology marker.ABSTRAKHipokotil dan kotiledon berpotensi untuk dijadikan sebagai marka morfologi yang efektif karena dapat dideteksi lebih dini. Informasi pola pewarisan karakter hipokotil dan kotiledon tomat belum banyak tersedia. Penelitian ini bertujuan untuk mempelajari pola pewarisan karakter kualitatif dan kuantitatif dari hipokotil dan kotiledon tomat sebagai marka morfologi pada tahap awal pertumbuhan tanaman. Penelitian ini menggunakan enam set populasi yaitu P1 hipokotil hijau (IPB T64), P2 hipokoti ungu (IPB T3), F1, F1R, BCP1, BCP2, dan F2. Karakter kualitatif menggunakan analisis Mendel dan pendugaan aksi gen karakter kuantitatif menggunakan analisis skala gabungan. Hasil analisis Mendel menunjukkan bahwa karakter warna hipokotil dikendalikan oleh dua pasang gen epistasis dominan-resesif. Gen pengendali warna ungu bersifat dominan terhadap warna hijau pada hipokotil tomat. Panjang hipokotil, panjang dan lebar kotiledon dikendalikan oleh banyak gen dan tidak ada pengaruh tetua betina berdasarkan uji sebaran populai F2. Hasil analisis skala gabungan menunjukkan bahwa aksi gen karakter panjang hipokotil dikendalikan oleh gen aditif dengan pengaruh epistasis aditif dominan, panjang dan lebar kotiledon dikendalikan oleh gen dominan dengan pengaruh epistasis duplikat. Semua karakter yang diamati memiliki nilai heritabilitas arti luas dalam tingkatan yang tinggi, sedangkan heritabilitas arti sempit dalam tingkatan yang sedang.Kata kunci: aksi gen, heritabilitas, hipikotil, kotiledon, marka morfologi.

Abstract

Okra merupakan tanaman dari suku Malvaceae yang memiliki aktivitas antidiabetik, dapat menurunkan dan menstabilkan kadar gula darah. Kandungan glibenclamide yang terdapat pada ekstrak etanol buah okra dapat merangsang sekresi insulin dari sel beta. Ketersediaan okra di Indonesia masih terbatas dan perlu ditingkatkan produksinya. Teknik induksi mutasi menjadi alternatif untuk meningkatkan keragaman tanaman okra yang keberadaan materi genetiknya sangat terbatas. Peneltian ini bertujuan untuk mendapatkan informasi LD50 dan seleksi individu terbaik tanaman okra untuk perbaikan daya hasil. Dosis iradiasi sinar gamma yang diaplikasikan pada benih okra yaitu 0 Gy hingga 900 Gy dan dilakukan analisis LD50, kemudian dilakukan iradiasi kembali pada dosis LD50. Hasil penelitian diperoleh nilai LD50 sebesar 574.08 Gy. Keragaman genetik yang tinggi hanya ditunjukkan pada karakter karakter jumlah buku dan jumlah buah. Karakter jumlah buku berhubungan erat dengan jumlah buah disebabkan oleh pengaruh langsung. Berdasarkan nilai korelasi, koefisien lintas, dan heritabilitas, karakter jumlah buku digunakan sebagai kriteria seleksi untuk mendapatkan galur okra berdaya hasil tinggi. Kata kunci: analisis sidik lintas, heritabilitas, korelasi, LD50

Abstract

A laboratory scale research to obtain environmentally safe effluent and liquid fertilizer from leachate from Final Waste Disposal Site in Galuga owned by Regional Government of Bogor City was conducted from July 2006 through to April 2007. The experiment was initiated by aerating the leachate in 4 difference aeration rates (0, 10, 30 and 70 liters/minute) followed by processing the sediment to product the liquid fertilizer. The experiment of production liquid fertilizer was carried out by adding lime with different dosage into sediment generated from processing by aerating at 70 liters/minute followed by centrifugation process or secher. Further, the liquid fertilizer generated from such experiment was applied to chilis planting (Capsicum annum). The research found that the processing conducted by aerating at the rate 70 liters/minute was the most effective in reducing pollutant from leachate. The addition of 1000 ppm CaO or Ca(OH)2 limes in sediment from aeration is the most effective in depositing the dissolved material compared to the addition of limes in other dosage. Liquid fertilizer generated through the addition of 1000 ppm CaO have the content of N = 375,83 ppm, P = 121,44 ppm, K = 948,11 ppm, Ca = 827,20 ppm, Mg = 959,50 ppm, S = 48,53 ppm, Cu = 8,23 ppm, Zn = 30,02 ppm, Mn = 230,57 ppm, Fe = 320,95 ppm, Pb = 10,34 ppm, Cd = 7,46 ppm and Cr = 2,05 ppm. The use of liquid fertilizer generated by adding 1000 ppm CaO was the most effective in enhancing vegetation growth and production of chili. The non essential elements (Pb, Cd and Cr) in fruits from vegetation given liquid fertilizer produced from such treatment did not exceed tolerable threshold.

Abstract

EnglishThe government of Situbondo Regency has not decided the location of  the agropolitan development. In this regard, a study on livestock-based regional sustainability development is necessary before the implementation of the agropolitan program  This study aims to analyze the sustainability index and the status of Situbondo area through five dimensions of sustainability. The study used a Multidimensional Scaling analysis (MDS) method called Rap-BANGKAPET and the results are shown in the form of sustainability index and status. The Leverage and Monte Carlo analyses were used to determine the attributes that sensitively affect the index and the status of sustainability and its impact. Sustainability analysis indicate that the ecological dimension is less sustainable (46.50%), economic dimention is sufficiently sustainable (69.53%), social and cultural dimensions is also sufficiently sustainable (55.14%), infrastructure and technology dimensions are at low level of sustainability (45.48%), and similarly at low level of sustainability for legal and institutional dimensions (47.46%). Of the 73 attributes, 24 of these attributes require direct treatment immediately because of its sensitive effect on sustainability index and status (significant at 95% of confidence level). The study suggests a progressive-optimistic scenario to improve the sustainability of the future status (long term) with overall improvement of sensitive attributes. IndonesianPemerintah Daerah Tingkat II Kabupaten Situbondo sampai saat ini masih belum menetapkan wilayahnya untuk pengembangan kawasan agropolitan. Untuk itu sebelum program agropolitan dilaksanakan perlu dikaji terlebih dahulu tingkat keberlanjutan wilayah berbasis peternakan di Kabupaten Situbondo. Penelitian ini bertujuan untuk menganalisis indeks dan status keberlanjutan wilayah berbasis peternakan di Kabupaten Situbondo ditinjau dari lima dimensi keberlanjutan, yaitu: dimensi ekonomi, sosial budaya, infrastruktur dan teknologi, serta hukum dan kelembagaan. Penelitian meggunakan metode analisis Multidimensional Scaling (MDS) yang disebut RAP-BANGKAPET dan hasilnya dinyatakan dalam bentuk indeks dan status keberlanjutan. Untuk mengetahui atribut yang sensitif berpengaruh terhadap indeks dan status keberlanjutan dan pengaruh galat dilakukan analisis Leverage dan Monte Carlo.   Hasil analisis keberlanjutan menunjukkan bahwa dimensi ekologi berada pada status kurang berkelanjutan (46,50%), dimensi ekonomi cukup berkelanjutan (69,53%), dimensi sosial budaya cukup berkelanjutan (55,14%), dimensi infrastruktur dan teknologi kurang berkelanjutan (45,48%), serta dimensi hukum dan kelembagaan kurang berkelanjutan (47,46%). Dari 73 atribut yang dianalisis, 24 atribut yang perlu segera ditangani karena sensitif berpengaruh terhadap peningkatan indeks dan status keberlanjutan dengan tingkat galat (error) yang sangat kecil pada taraf kepercayaan 95 persen. Dalam rangka meningkatkan status keberlanjutan ke depan (jangka panjang), skenario yang perlu dilakukan adalah skenario progresif-optimistik dengan melakukan perbaikan secara menyeluruh terhadap semua atribut yang sensitif dalam peningkatan status kawasan.

Abstract

Abstrak. Rendahnya produktivitas kopi merupakan salah satu permasalahan utama dalam sistem produksi kopi Indonesia. Hal ini diantaranya disebabkan tidak adanya perawatan kopi yang optimal dengan memperhatikan fase fenologi kopi, serta dampak variabilitas dan perubahan iklim. Berbagai teknologi adaptasi kopi sudah banyak dihasilkan namun langkah adaptasi dengan memanfaatkan prakiraan iklim dalam bentuk penyesuian kegiatan budidaya dengan fase fenologi atau disebut sebagai kalender budidaya belum dikembangkan. Tulisan ini memaparkan tentang dampak variabilitas dan perubahan iklim pada tanaman kopi, teknologi adaptasi kopi yang sudah tersedia, perlunya pengembangan kalender budidaya kopi sebagai bentuk strategi adaptasi dan peningkatan produktivitas serta potensi dan tantangan pengembangan kalender budidaya kopi di Indonesia. Hasil review ini menunjukkan kalender budidaya kopi berpotensi dikembangkan sebagai strategi peningkatan produktivitas serta adaptasi terhadap variabilitas dan perubahan iklim. Abstract. Low productivity is one of the main challenges in Indonesia's coffee production system .It is low due to cultivation management; most of the coffee farmer does not manage their plantation base on the coffee phenology phase.  Moreover climate variability and change also have important effect on coffee productivity. Various technologies on adaptation and measurement to climate change and variability have been identified. Unfortunately, the technology which use climate forecast through adjusting cultivation activity and coffee phenology called as cultivation calendar do not exist yet. This paper provides an overview on the impact of climate variability and change to coffee production, the existing adaptation strategy, and the importance of cultivation calendar as a strategy for adapting and increasing productivity, and the potential and challenges to develop cultivation calendar in Indonesia. This review reveals that coffee cultivation calendar is a potential strategy for increaseing productivity and adapting climate change and variability.

Abstract

ABSTRAK. Bandung sebagai salah satu kota metropolitan yang berkembang di Indonesia tidak dapat menghindar dari masalah-masalah yang berkaitan dengan permukiman kumuh. Masalah permukiman kumuh biasanya dikarakteristikan dengan menurunnya kondisi lingkungan seperti masalah keterbatasan ketersediaan air tanah dan polusi. Berdasarkan fakta-fakta tersebut, penelitian ini bertujuan untuk mengkalkulasi kesenjangan sumber daya dalam hal kuantitas maupun kualitas air dan tanah, bagi masyarakat yang tinggal di daerah kumuh di Kota Bandung yang didasari pada standar pelayanan minimum dan standar kualitas lingkungan serta menentukan bentuk dari infrastruktur dasar seperti penyedia pengganti dari sumber daya alam air dan tanah yang paling tepat. Penelitian ini menetapkan tiga kelurahan yang mewakili tia tipologi kawasan kumuh yaitu, kumuh berat pada Kelurahan Tamansari, kumuh sedang pada Kelurahan Babakan Ciamis, dan kumuh ringan pada Kelurahan Cihargeulis.  Hasilnya menunjukkan bahwa kaitannya dengan kuantitas air pada ketiga kelurahan tersebut dipenuhi dari air tanah dan juga sumber PDAM. Hal ini mengingat bahwa ketersediaan tanah untuk perumahan pada ketiga kelurahan tersebut sudah mencukupi. Sementara bila dikaitkan dengan kualitas air pada ketiga kelurahan, nampaknya kualitas air dari PDAM memenuhi standar lingkungan namun kualitas air dari air tanah tidak memenuhi standar tersebut. Sehingga untuk kualitas tanah dengan mengacu pada Soil Quality Index dari BPS terlihat bahwa indeks kualitas tanah di Kelurahan Tamansari-lah yang paling rendah, dan di Kelurahan Cihargeulis-lah yang paling tinggi. Bentuk dari prioritas infrastruktur pada Kelurahan Tamansari untuk pengadaan air adalah melalui pipa dari PDAM atau pengolahan air permukaan tanah tingkat kelurahan, sementara untuk air buangan adalah MCK untuk “black water” dan instalasi pengolahan air buangan untuk “grey water”. Sementara itu untuk buangan padat adalah merupakan buangan bukan organik dan pengolahan kompos buangan organik serta dari buangan rumah berlantai banyak atau hunian vertikal. Bentuk dari  prioritas infrastruktur dari Kelurahan Babakan Ciamis untuk air adalah sama dengan Kelurahan Tamansari. Sementara itu pada Kelurahan Cihargeulis, prioritas infrastruktur untuk air adalah juga melalui pemipaan PDAM, dan untuk buangan air menggunakan instalasi pengolahan air buangan pada tingkat kota, untuk buangan padat adalah merupakan buangan bukan organik, pengolahan kompos buangan organik dan perumahan horizontal.  Kata Kunci: kumuh, sumber daya alam dan air, standar layanan minimum, standar lingkungan, insfrastruktur dasar permukiman  ABSTRACT. Bandung as one of the growing metropolitan in Indonesia did not escape from the problems of slums emerging. The problem of slums is characterized by such as a decrease in environmental conditions such as lack of raw water availability and pollution. Based oh those facts, this study aimed to calculate the resource gap in terms of quantity and quality of water and land, for people living in the slums in Bandung city based on minimum service standards and environment quality standards, and determining the form of basic infrastructure as a substitute provider of natural resources water and land that most appropriate. The study was conducted in three kelurahan which represent the three typologies of slums that are heavy is Kelurahan Tamansari, moderate is Kelurahan Babakan Ciamis, and light is Kelurahan Cihargeulis.   The results showed that in terms of quantity water in the three kelurahans are met from the ground water and piped water from PDAM.  As for the existing land for housing in the three kelurahans are sufficient. In terms of water quality in the three kelurahans is seen that the quality from PDAM have met the environment standards but the quality from ground water have not.  Then for soil quality with reference to Soil Quality Index of BPS was seen that the Land Quality Index in the Kelurahan Tamansari is the lowest, and Kelurahan Cihargeulis is the highest.  The shape of the priority infrastructure for Kelurahan Tamansari for water is piping from PDAM or local surface water treatment, for wastewater is MCK Communal for black water and local wastewater instalation treatment plant for grey water, for solid waste is anorganic waste bank and composting for organic waste, and multistorey housing.  The shape of the priority infrastructure for Kelurahan Babakan Ciamis for water is piping from PDAM, for wastewater is MCK Communal for black water and local wastewater instalation treatment plant for grey water, for solid waste is anorganic waste bank and composting for organic waste, and multistorey housing. The shape of the priority infrastructure for Kelurahan Cihargeulis for water is piping from PDAM, for wastewater is city level wastewater installation treatment, for solid waste is anorganic waste bank and composting for organic waste, landed housing Keywords: Slums, water and natural resources of land, minimum service standards, environmental standards, the basic infrastructure of the settlements

Abstract

As a company engaged in the industrial sector by producing certain components and localized in an industrial area, there will be an impact on the environment. These impacts can be positive in the form of employment, reducing dependence on imported heavy equipment, increase in foreign exchange due to reduced imports and increased exports, increased government revenue from taxes, public facilities improvement and supporting infrastructure, and opening up opportunities for other related industries. These impacts can also be negative in the form of environmental degradation such as noise disturbance, dust, and micro climate change, and changes in social and cultural conditions surrounding the industry. Data analysis was performed descriptively and with the Structural Equation Model (SEM). SEM is a multivariate statistical technique which is a combination of factor analysis and regression analysis (correlation), which aims to test the connections between existing variables in a model, whether it is between the indicator with the construct, or the connections between constructs. SEM model consists of two parts, which is the latent variable model and the observed variable model. In contrast to ordinary regression linking the causality between the observed variables, it is also possible in SEM to identify the causality between latent variables. The results of SEM analysis showed that the developed model has a fairly high level of validity that is shown by the minimum fit chi-square value of 93.15 (P = 0.00029). Based on said model, it shows that the company's performance in waste management is largely determined by employee integrity and objectivity of the new employees followed later by the independence of the employees in waste management. The most important factor that determines the employee integrity in waste management in the model is honesty, individual wisdom, and a sense of responsibility. The most important factor in the employee objectivity in waste management is the support of accurate data in each report of waste management by the company and transparency on reports of the company’s activity. While the factors that determine the employee independency is the company's interests, a sense of employee volunteering, and openness between the company and employees. Keywords : heavy equipment industry, management, environment, Structural Equation Model (SEM)
