<p>Sago development requires plant material as superior seedlings for rehabilitation and replanting. Until 2016 two superior sago varieties were released, namely Molat sago varieties from Maluku in 2011 and Selatpanjang Meranti sago varieties from the Meranti Islands Regency, Riau in 2013. Indragiri Hilir Regency, Riau Province is one of the areas of natural sago growth, and producing sago starch . This district has the opportunity to develop sago palms as a potential and regional producer. In connection with that, a research has been conducted which aims to find out and obtain superior sago species from Indragiri Hilir Regency, from 2015 to 2017. The research method was conducted by observing the sago population with high yield potential. For the observation, 10 sample trees every year were selected in each location/village in Gaung Anak Serka District, Indragiri Hilir Regency, Riau Province. Data observations were carried out on the morphological characteristics of sago and suckers, sago starch production potential, and proximate analysis. Observation data were analyzed for diversity, standard deviation and coefficient of variance. Morphological observations and production of Bestari sago starch obtained an average leaf length of 8.00 m, diameter of the diameter of bottom stem 47.37 cm, circumference of the bottom stem 148.52 cm, the number of leaf scars on the leaf-free stem 53.23 scars, the number leaves on the crown 16.98 strands, the distance of leaf scar 12.42 cm, the length of the petiole 231.00 cm, the width of the petiole 9.25 cm, the thickness of the petiole 3.93 cm, the length of the rachis 660.33 cm, the length of the leaflets 155.59 cm, leaflets width 9.39 cm, and dry starch yield 254.94 kg per palm. Proximate analysis results on Bestari sago starch obtained an average water content of 13.00%, ash content of 0.60%, fat content of 0.83%, protein content of 0.84%, crude fiber content of 0.29%, and carbohydrate content was 84.34%, with 350 calories, Vitamin C 0.96 mg/100 gr sago starch, and total sugar around 1.43%.

The main content of coconut kernels are fats and fatty acids as well as protein and amino acids, and these contents vary among the varieties. This variation of amino acids and fatty acids also occurs in Indonesian tall coconut varieties. The objective of this study was to characterize amino and fatty acids content of Indonesian tall coconut varieties, namely Mapanget Tall, Palu Tall, Bali Tall, Tenga Tall, Selayar Tall, OdeskaLobu Tall, Babasal Tall, and Mastutin Tall. This study was conducted in Manado and Bogor from 2014 - 2019 by using an observational method. The results showed that the coconut kernel has eight types of non-essential amino acids and eight types of essential amino acids. Palu Tall has the highest amino acid content: alanine, arginine, aspartate, glutamate, glycine, serine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, and valine. Mapanget Tall has the highest contents of caprylic, capric, and lauric fatty acids, each with 9.04, 6.71, and 53.67 %, respectively. The result of this study can be used to develop varieties to obtain coconuts with high essential amino acids and fatty acids for the production of VCO, desiccated coconut, and other raw food materials.

“Cungap” red (CR) coconut is an exotic coconut that has specific characters, i.e. the husk contains high antioxidant components. The study aimed to evaluate the physicochemical and phytochemical characteristics of CR coconut (husk, kernel, and water). Tender and mature CR coconut fruits were collected from farmers at Sukarena Village, Ciomas District, Serang Regency, Banten Province. The mature nuts were evaluated for the physicochemical characteristics (moisture, protein, ash, fat and fatty acids profile). Vitamins and minerals were measured from the young coconut water. Anthocyanin and β-carotene were analysed from the tender nuts (husk, meat, and water). The results showed that CR kernel contained 8.35% of water, 2.02% of ash, 7.13% of protein, and 60.09% of fat. The medium-chain fatty acids were mainly from the coconut kernel fat (52.55%). Lauric acid was the major fatty acid (45.89%). The Majority of minerals (calcium, phosphorus, potassium, and magnesium) contained in the coconut water; potassium content was the highest (289.95 mg/100 ml). The β-carotene content in the husk and kernel were 18.43/100g and 1.28 mg/100g, respectively. Also, the anthocyanin contents in the husk, kernel, and coconut water were 8.01 mg/100 g, 1.5 mg/100 g, and 0.8 mg/100 g, respectively. The study implies that CR coconut is potential as anthocyanin, β-carotene, and mineral sources for human health.

<p>Coconut improvement programs require knowledge of the effect of morphological characters on the coconut yield. The study aimed to determine the effects of fourteen morphological characters on the production of coconut meat character on Kampung Laut and Pengabuan tall coconut. This study was conducted in Kampung Laut and Pengabuan Villages, Jambi Province. Correlation analysis among 15 characters of vegetative, generative, and fruit components used the Walpole formula (1992). Fourteen characters affecting meat production were analyzed by using Path analysis of Singh and Chaudary formula following the R i386 3.5.2 software package in the Agricole package. Correlation analysis resulted in the characters of the number of leaves, number of bunches, number of fruits, polar circumference of fruit, weight of unhusked fruit, equatorial circumference of nut, and weight of endosperm correlated with the production of endosperm, on Kampung Laut tall coconut, while Pengabuan tall coconut have number of fruits, equatorial circumference of nut, and weight of endosperm. The results of path analysis showed that the characters of the number of bunches, number of fruits, and weight of endosperm had a significant direct effect on the production of endosperm on the Kampung Laut tall coconut. While on the Pengabuan tall coconut, only the fruits number and endosperm weight affected the endosperm production. The study indicates that the number of bunches, number of fruits, and weight of endosperm can be used as selection criteria to increase the production of the endosperm of the Kampung Laut and Pangabuan tall coconut.</p><p><strong>Keywords:   </strong>Morphological characters, correlation, fruit components, selection</p><p> </p><p><strong>Abstrak</strong></p><p>Program perbaikan tanaman kelapa membutuhkan pengetahuan tentang pengaruh karakter morfologi terhadap hasil.
