Abstract

Kalimantan Island is rich in genetic resources and species diversity of Durio spp. Of the 27 durian species in the world, 18 species are found in Borneo. The large number of Durio species that grow in Kalimantan illustrates that this area is the most important distribution center for durian relatives. Two of the best-known edible durians in East Kalimantan are Durian (Duriozibethinus) and Lai (Durio kutejensis). However, as a plant with a cross-pollination mechanism, there are many results of natural crosses between the two. The study aimed to identify Durian x Lai plants in Loa Kulu, Kutai Kertanegara, East Kalimantan Province, Indonesia as the superior local fruit crops potentially agribusiness industry. This research was carried out by collecting data and information about the morphological characteristics of the plants and fruits from D. Zibenthinus x D. Kutejensis. The results of the study successfully identified 6 potentially superior plants that are believed to be the result of a cross between D. Zibenthinus x D. kutenjensis. The 6 potential superior plants were found to have different morphological characters. This is the initial identification and being a basis of the next research phase, which is to identify the morphology of trees, flowers, and fruit to obtain new cultivars crossing D.zibenthinus and D. Kutejensis which have superior potential as superior commodities from East Kalimantan.

Abstract

Unlike conventional agriculture, urban hydroponics are widely on a small yard scale.  Hydroponics is a term used for farming without using soil as a growth medium. Plants can be planted in pots or other containers using water and other porous materials as growing media. Cheap, easily obtainable, and efficient growing media types are needed for urban communities to cultivate vegetable crops, especially shallots (Allium ascalonicum L.). Shallots have an important meaning, both in terms of high economic value and their nutritional content. It is unknown if the shallots are cultivated in a hydroponic system and how the performance of its roots and the suitable simple growing media for growing shallots in hydroponic will be enhanced. Therefore, this research was conducted to study the performance of shallot roots in several alternative hydroponic media and obtain growing media that can provide the best growth on the performance of shallot roots in the hydroponic system. The experiment was conducted in 3 months at the Glass House and Integrated laboratory of the Faculty of Agriculture, Mulawarman University, Indonesia. This research was arranged in a Randomized Block Design (RBD) with four replications. The factor is the growing media (m) which consists of 4 levels, namely: m1 = sand (± 80-100 mesh); m2 = burnt rice husk; m3 = egg cartons; and m4 = wood shavings (± 90-120 mesh). Data retrieval by observing the following parameters: Leaf length (cm), Number of leaves (strands), Number of plant bulbs (bulbs), bulbs wet weight (grams), bulbs dry weight (grams), Longest root length (cm), and Total root length (m). This research showed that the burnt rice husk and wood shavings growing media influence the growth and performance of the shallots' roots (Allium ascalonicum L.) plants and can be used as the simple growing media in urban hydroponic as Household scale cultivation. On the other hand, the growing media from sand and egg cartons are not recommended for growing shallots in the hydroponic system.

Abstract

The large number of Durio species that grow in Kalimantan illustrates that this area is the most important distribution center for durian relatives. Two of the best-known edible durians in East Kalimantan are Durian (Durio zibethinus) and Lai (Durio Kutejensis). Several studies have been conducted to determine the effect of calcium on the quality of fruits. However, very little information was obtained regarding the effect of Ca on the quality of lai-durian fruit. This research was carried out by collecting data and information about Fruit performance and edible part nutritional value three D. zibenthinus x D. kutejensis plants. The five potential superior plants have some similar in rind moisture factor, ash content, water content, total fat, crude protein, and total dissolved solids. However, there is a difference in flesh thickness which indicates that LK4 has the thickest flesh thickness with an average of 9mm, while LK5 shows the thinnest average flesh thickness of 4mm. Meanwhile, when viewed from total carbohydrates, LK3 fruit has the highest total carbohydrate content compared to other fruits, which is 37.477 and energy is 180.357 kcal. This study indicates that there is a negative correlation between fruit peel size and calcium content. In large Lai-durian fruits such as LK4 fruit there is a lower amount of calcium than other fruits.

Abstract

This study was conducted to determine the interaction of CaCl2 concentration and application technique on the tomato plant performance and storability of tomatoes. The CaCl2 concentration (K) consisting of k0 (0 mL L -1 ), k1 (0.5 mL L -1 ), k2 (1.0 mL L -1 ), k3 (1.5 mL L -1 ), k4 (2.0 mL L -1 ) and application technique (T) consisting of t1 (sprayed on the plant) and t2 ( watered into the growing media). The results shows that k2t2 combination obtained the maximum number of flowers with an average 24.33 florets and obtained height of tomato plant. The maximum number of fruits was obtained by k3t2 combination (11.33 florets), followed by k4t2 combination (11.00 florets). The minimum number of flowers fall off was obtained by k0t2 combination (1.00 florets) and the maximum number of flowers fall off was obtained by k3t1 combination (4.67 florets). The combination of k4t1 and k4t2 gave the best results on blossom endrot diseases (zero diseases) and storability of tomatoes (up to 30 days). Key words: tomato, calcium chloride (CaCl2), performance, storability

Abstract

The Central Mahakam region is a peat swamp ecosystem with cascade lakes in East Kutai, West Kutai, and Kutai Kartanegara. The region has abundant potential for taro plants (Araceae). The community uses taro only for food and is not used as a feed ingredient. This research aims to identify the types and potential of taro for use as animal feed. Observations were conducted in two villages in the Central Mahakam region: Batuq and Tuana Tuha Villages, Muara Muntai District, Kutai Kartanegara Regency. Taro samples will be taken based on habitat and then subjected to proximate analysis to determine chemical content. The method used in this research was exploratory. The results of identifying the types of taro in Batuq Village showed four types of taro, while there were two types in Tuana Tuha Village. The taro-growing habitat for the Colocasia sp species is terrestrial/semi-terrestrial, while the Xanthosoma sagittifolium species grows terrestrially. The part of taro that can be used as food is in the form of leaves. The chemical content of taro leaves (Colocasia esculenta) dry weight is 90.39%, crude protein is 4.62%, Ash is 4.51%, crude fat is 1.01%, and crude fiber is 3.86%. The Xanthosoma sagittifolium type contains 90.52% dry weight, 4.47% crude protein, 4.39% ash, 1.06% crude fat, and 3.56% crude fiber. There are six types of taro found in the Central Mahakam region, and they have the potential to be an alternative food source based on their chemical content.
