Abstract

Sagu Baruk Palm (Arenga microcarpha) is an endemic plant and producing carbohydrates as main source of local food to the people in Sangihe Island . The aim of this study is to analyze the production of  the sago and to analyze its the chemical composition and nutritional value. The research was conducted from October 2010 to June 2011 at Gunung Village Tabukan Tengah Regency Sangihe district Island. The village is spread from the coast up to the top of the hill with an altitude of ± 600 meters above sea level. The data analysis techniques in this research is descriptive analysis, F test, ANOVA. The results showed that the production of Sagu Baruk Palm at the third height position for the stem lenght 9.7-11m and stem diameter 14.3-15.7cm obtain wet sago flour 44-44.3kg and the stem rendemen from 21.3% to 22.3%, statistically only stem weight and pith weight has a significant different. The highest stem weight obtained at the bottom position, the highest pith weight obtain at the top position, and for the higest stem rendemen obtain at the top position . The chemical composition were significant differences in levels of protein, calcium, iron, magnesium, and pH at the three height positions. Key words: Superior local food sources, stem rendemen, production, sagu baruk palm.

Abstract

Indonesia memiliki keanekaragaman hayati tanaman durian yang tergolong tinggi sehingga perlu dilakukan kegiatan eksplorasi untuk mengumpulkan informasi jenis-jenis durian unggul sebagai bahan untuk meningkatkan keanekaragaman nilai genetik tanaman. Tujuan dari penelitian ini adalah untuk mengetahui informasi keanekaragaman genetik dan kekerabatan durian yang ada di Kabupaten Trenggalek, Provinsi Jawa Timur berdasarkan karakter morfologi pada ketinggian lahan yang berbeda. Penelitian telah dilaksanakan pada bulan Januari sampai Maret 2020. Metode pengambilan sampel tanaman menggunakan metode random sampling dengan sistem diagonal sampling. Data hasil klasifikasi morfologi berupa data biner dianalisis menggunakan Unweighted Pair Group Method with Aritmathic Means (UPGMA) melalui program NTSYSpc 2.02 untuk mengetahui hubungan kekerabatan tanaman berdasarkan jarak genetik dan disajikan dalam bentuk dendogram. Hasil penelitian menunjukan durian lokal memiliki karakter yang beraneka ragam. Keragaman karakter 25 aksesi durian memiliki 89 macam karakter terdiri atas karakter pohon, daun, dan buah. Hasil dendogram dari 25 aksesi durian yang ditemukan menunjukkan koefisien kemiripan 61 - 84% pada karakter kualitatif morfologi aksesi.

Abstract

Kelapa sawit (Elaeis guineensis Jacq.) merupakan komoditi perkebunan yang mempunyai peran penting dalam berbagai aspek kehidupan. Pengembangan industri kelapa sawit memerlukan beberapa upaya untuk mencapai peningkatan produktivitas nasional, salah satunya adalah pemanfaatan benih unggul bermutu didukung oleh ketersediaan sumber daya genetik (plasma nutfah) yang mempunyai tingkat keragaman genetik yang tinggi. Upaya yang dapat dilakukan melalui karakterisasi kelapa sawit introduksi dari luar. Maka dari itu penelitian ini bertujua untuk menganalisis jarak genetik antar aksesi kelapa sawit introduksi asal Kamerun berdasarkan karakter morfologi untuk memperkaya genetik. Penelitian ini telah dilaksanakan pada bulan Januari-Maret 2018 di Pusat Penelitian Kelapa Sawit kebun unit Adolina milik PT. Perkebunan Nusantara IV, Serdang Bedagai, Sumatera Utara. Pengamatan dilakukan menggunakan metode single plant pada 47 aksesi kelapa sawit inroduksi Kamerun dan  10 sampel varietas DxP PPKS 540. Analisa data yang digunakan adalah analisis deskriptif, PCA (Principal Component Analysis) dan analisis kluster. Hasil analisis PCA pada 47 aksesi kelapa sawit asal Kamerun menghasilkan 6 komponen utama yang memiliki eigenvalue > 1, sedangkan PCA pada DxP PPKS 540 menghasilkan 5 komponen utama yang memiliki eigenvalue >1. Analisis selanjutnya adalah analisis kluster. Analisis kluster dilakukan menghasilkan Euclidean distance pada aksesi Dura asal Kamerun sebesar 37%, pada aksesi Tenera asal Kamerun sebesar 19%, pada 47 aksesi asal Kamerun sebesar 57%, pada DxP PPKS 540 sebesar 16% dan pada 47 aksesi asal kamerun digabungkan dengan DxP PPKS 540 sebesar 61%.

Abstract

This research aimed to investigate the incompatibility levels of controlled cross-pollination in sweetpotato, based on normal seedling percentage and their correlation with seed vigour. The controlled cross-pollination in sweetpotato faces issues due to its cross-incompatibility and self-incompatibility characteristics. Currently, the incompatibility level in sweetpotato is investigated based on the fruit set percentage. However, this criterion lacks the ability in accurately predicting the number of new clones. Therefore, it is essential to study new parameters to create a better investigation of incompatibility in sweetpotato. The materials used in this research consisted of eight sweetpotato clones as female and four sweetpotato clones as male parents. Cross-pollinations were done reciprocally. The experiment was conducted at Indonesian Legume and Tuber Crops Research Institute from April to December 2014. The result showed that totally 5,188 times crossing produced about 25% fruit sets and 10% normal seedlings. The use of normal seedlings percentage as a new parameter in evaluating cross-pollination has apparently seemed to be more effective than the fruit sets percentage method because numbers of new clones could be known accurately. This research revealed that the normal seedling could be used as a new parameter in determining the incompatibility level in sweetpotato controlled cross-pollination.

Abstract

The research objective was to select wheat genotypes that can adapt on the medium and low plains. Twenty-seven genotypes and three varieties of wheat were grown in four locations in the medium and low plains since June-October 2009. The experiments were arranged using a randomized complete block design repeated three times. Analysis of variance performed at each location followed by a test of homogeneity of error range, the combined analysis of variance and yields stability analysis. Genotype x environment interaction significantly affecting yield. Stable genotypes and widely adaptable across locations were G-1 (1.94 t.ha-1), G-20 (1.24 t.ha-1), H-14 (1.85 t.ha-1), H-19 (1.59 t.ha-1), H-20 (1.69 t.ha-1), H-21 (1.48 t.ha-1), 162 (1.62 t.ha-1), 80 (1.63 t.ha-1), 82 (1.78 t.ha-1), 91 (1.49 t.ha-1), and 142 (1.45 t.ha-1). Genotypes adapted in productive environment were G-18 (1.23 t.ha-1), G-19 (1.63 t.ha-1), 185 (1.30 t.ha-1), 40 (1.33 t.ha-1) and 42 (1.52 t.ha-1). Genotypes adapted in marginal environments were 28 (2,22 t.ha-1), H-1 (1.61 t.ha-1), H-8 (1.65 t.ha-1) and H-16 (1.68 t.ha-1). Genotype was selected as an improvement material in the wheat breeding in medium and lowland of tropical regions.   Keywords: wheat selection, tropical, yield stability and adaptability
