Abstract

The productivity of strawberry (Fragaria sp.) depends on the presence of pollinator insects that need nectar or pollen as their food. The diversity and the population size of pollinator insects can be increased by the companion planting of Borreria laevicaulis among the strawberry. This research aimed to determine the diversity of pollinator insects of strawberry plantation companion by B. laevicaulis and to determine the relationship between the diversity of pollinator insects with the strawberry fruit produced. This research was conducted in the strawberry plantation of Serang Village, of the District Karangreja, Purbalingga, from June to August 2012. The research was designed to determine the effect of companion planting of B. laevicaulis at the 0%, 5%, 10%, and 15% of the total individuals of strawberry. The results showed that the companion planting of B. laevicaulis in the strawberry field did not affect the species diversity of pollinator insects. But the B. laevicaulis companion planting affected the amount of strawberry yielded. The maximum yield was obtained by planting B. laevicaulis at the 10% of the strawberry individuals; it was increased by 76.12% of the control without companion planting.

Abstract

Increased carbon dioxide in the atmosphere causes global climate change seriously. Forests serve as an important asset that can absorb and store carbon in the form of biomass. One type of potential forest as a carbon sink is forests resin. The amount of carbon stored by standing very dynamic and varies according to the age of its standing. Therefore, studies will be needed to determine the effect of age on biomass and carbon stocks stands resin, determine the relationship between age and standing biomass and carbon stocks resin, and knowing the optimum resin stand age in storing biomass and carbon stocks. This research was conducted at the stands of resin RPH Karang Gandul, KPH Banyumas Timur for four weeks in May 2016. The method used is a survey with a sampling technique using cluster random sampling. Stands resin used in the study were classified into five age groups with 5 replicates. Data were analyzed using ANOVA with an error rate of 5% and continued with LSD for further test results were significant and regression analysis to determine the relationship of age with biomass and carbon stocks stands resin. The results showed that the age effect on biomass and carbon stocks stands resin, the relationship formed between the age of stand with biomass and carbon stocks are quadratic, and age optimum in storing biomass and carbon stocks is 35 years.

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.

Abstract

Bombus rufipes Lepeletier 1835 (Hymenoptera: Bombidae) is the only species of Bombidae found in Java. Recent information suggests that it occurs in Java on Mounts Salak 1200 m asl., Mt. Halimun, Mt. Pangrango Gede Complexes, Mt.Cermai, (West Java) Mt.Slamet , Mt. Merapi, Mt. Merbabu, Mt Telomoyo (Central Java) and Mt Argopuro (East Java) , at altitudes above 1,500 m asl. We sought to rediscover this species on Mount Slamet by surveying natural forests at altitudes of 1,500–2,500 m asl on the eastern slopes of Mount Slamet, from August to October 2020 and August to October 2021. Descriptive and morphometric data were obtained and analyzed. The survey revealed five colonies nesting on the ground at an average depth of ca. 70 cm; the colonies contained 18–24 individuals and 22–36 cells (brood, honey, and pollen cells). Based on morphometric measurements and the description of Frison (1930), the species was identified as Bombus rufipes Lepeletier 1835. Therefore, Bombus rufipes still occurs on Mount Slamet. These results provide basic information that should aid further research on this species.

Abstract

Cinnamomum sintoc Blume is an endangered species experiencing an ongoing decline due to overharvesting; in- and ex-situ conservation efforts are urgently needed to ensure its survival. We performed a detailed assessment of the flowering and fruiting phenology of C. sintoc in a lowland forest in West Java, Indonesia. We aimed to relate the duration of each phenological phase to environmental factors including elevation, humidity, temperature, and slope, as well as the orientation of the flowers. A total of 30 trees were sampled from three elevation ranges (500–700, 700–900, and 900–1,100 m). We found that C. sintoc requires approximately 40 days to complete flowering and an additional 82 days to produce mature fruit. The period from flower initiation to fruit ripening spans 4 months, from late July to early November. Flowers that are east-facing developed mature fruit more rapidly than those facing other directions, and the shortest flowering and fruiting phenological period was observed for east-facing flowers at 700–900 m. These results provide a baseline for studying phenological shifts in C. sintoc, and could inform seed harvesting efforts for conservation projects in the study area of Gunung Cermai National Park.

Abstract

Purwaceng (Pimpinella pruatjan Molkenb.) yang termasuk suku Apiaceae adalah herba tahunan yang berbau aromatis, berukuran kecil, tumbuh mendatar di atas permukaan tanah seperti tumbuhan pegagan dan semanggi gunung namun tidak merambat. Purwaceng hanya tumbuh di pegunungan tinggi di Jawa. Populasi purwaceng makin lama makin rendah sementara permintaan industri tinggi, sehingga semakin langka. Ada beberapa tumbuhan dengan mirip dengan purwaceng seperti Valeriana javanica, V. officinalis, Centella asiatica ungu, Lobelia nummularia dan lain sebagainya. Penelitian ini bertujuan untuk mengetahui perbedaan antara purwaceng asli dan tumbuhan lain yang sering dianggap purwaceng. Metode yang digunakan dalam penelitian ini adalah survei Dataran Tinggi Dieng dan sekitarnya. Selanjutnya sampel dikarakterisasi secara morfologis. Hasil peneliti ini menunjukkan bahwa ada beberapa perbedaan antara purwaceng dengan valerian (purwaceng palsu).

Abstract

In agricultural landscape in northern slope of Mount Slamet, diversity of wild bee species as pollinator depend on forested habitats. This study aimed to assess the effects of distance from the forest edge on the diversity of wild bees on strawberry and tomato crops. This study was conducted from July 2014 to October 2014. The experimental fields contained tomato and strawberry with a total area of 4 ha (2 ha each) and divided into five plots based on distance from the forest edge (0, 50, 100, 150, and 200 m). Wild bee was catched with  kite netting  in 7.00 -9.00 in ten consecutive days. Wild bee diversity differed according to distance from the forest edge, the highest value was at 0 m for strawberry plots (H’ = 2.008, E = 0.72 and Chao1= 16) and for tomato plots, the highest diversity was at 50 m from the forest edge (H’ = 2.298, E = 0.95 and Chao1= 11) and the lowest was at 200 m in both plots. Wild bee species richness and abundance decreased with distance, resulting in the minimum diversity and abundance of wild bee at 200 m from forest edge in both crops. How to CiteWidhiono, I., Sudiana, E.
