Abstract

Salak or snake fruit (Salacca zalacca) or salak is a kind of popular fruit originated from Sumatra and Java. There are many cultivars including both the wild and the hybrid ones. One of many cultivars namely S. zalacca ‘Kelapa’ was observed for their distribution.  This cultivar is considered to be unusual because it has only a few spines on its petioles. This cultivar was previously found only in Karangasem Bali especially in the subdistrict of Sibetan, Selat, and Rendang and in Batujajar in West Java.  A new record was found in Banjarnegara especially in Sokanandi Village. A map of the distribution of this cultivar is presented.

Abstract

Research aims to conduct diversity and productivity of indigenous forage in different levels vegetation density in Gombong-Selatan karst mountain. We used survey method to explain the research by sampled three location of vegetation density, they are moderate, high, and very high. In each location vegetation density we take five parts by using random sampling. Then, a descriptive technique is used to analyzed the indigenous forage diversity data result whereas variance analysis is used to analyzed the productivity.The results shows the highest diversity of indigenous forage in Gombong-Selatan karst mountain is in moderate vegetation density area where has 36 species, high vegetation density has 20 species, and the highest vegetation density has 16 species. Eragrotis amabillis, Oplismenus burmannii, Centrosema pubescens, Ageratum conyzoides and Urena lobata are the dominant indegenous forage species in Gombong-Selatan karst mountain. The variances result shows that indigenous forage productivity in Gombong Selatan karst mountain is influenced by vegetation density. We found that lowest productivity is in high vegetation density.

Abstract

Snake fruit (Salacca zalacca (Gaertner) Voss) is originated from Indonesia. The aim of this study was to find out the cultivar diversity of salak pondoh in Banjarnegara, and to determine the similarity relatiinshipa between cultivars pondoh in Banjarnegara. The method used was exploratory survey with purposive random sampling. Morphological characteristics observed included 50 characters in the form of stems, leaves, flowers, fruits, seeds, and spines. Samples were taken at 5 districts namely Madukara, Banjarmangu, Sigaluh, Pagentan and Banjarnegara. The result of this research showed that there were six cultivars of Salacca zalacca namely cultivars ‘Pondoh Nglumut’, ‘Linting’, ‘Ketek’, ‘Manggala’, ‘Madu’, and ‘Super’. Whereas in S. zalacca Pondoh Ketek has various number of seeds in the fruit. The most closely related cultivars were ‘Pondoh Nglumut’ and ‘Super’. The most distinct cultivars were S. zalacca ‘Manggala’ and ‘Ketek’.

Abstract

A study on the morphological variation of tali bamboo [Gigantochloa apus (Schult.f.) Kurz] has been conducted at various altitudes of Sub Watershed Pelus Banyumas, Central Java. This study was aimed at determining the morphological variations in relation to altitudes above sea levels. The method used was survey with stratified sampling.  The variables measured included culm diameter, culm internode length, culm sheath length and width, ovate-triangular blade length and width, leaf blade length and width, stem color and hairs, and altitude. The results of this study indicated that the altitudinal difference effect some morphological characteristics of tali bamboos such as: 1) green young seedling with black hairs found at 200-299 m and 300-399 m asl. 2) morphological variations are effected by altitude. Tali bamboo grows optimally at the altitude of 400 to 499 m asl. The results of regression analysis showed that the altitude has a relatively close correlation with somes of morphological character of tali bamboo.
