Abstract

The purpose of this study was to determine the weed density and the dominant species of weeds in Malapari (Pongamia pinnata (L). Pierre) agroforestry. The study was conducted in Patutrejo Village, Grabag District, Purworejo Regency. The method used is single plot method in malapari agroforestry, as a comparison of observations of weeds on empty land that is not planted. Weed sample collection was carried out by the quadratic method measuring 1 m x 1 m as many as 3 plots placed in malapari agroforestry and empty land diagonally. Observations were repeated 3 times so that there were 18 observation plots. The results showed that weed density in malapari agroforestry (29.95) was lower than empty land (54.17). The dominant species of weeds in both malapari agroforestry and empty land is Eulalia amaura (Buese) with Important Value Index (IVI) of 36.40 % and 43.39 %. This species is a pioneer weed and fast growing, so monitoring and control are needed so that the weed population is not economically disserve.Keywords: agroforestry, density, dominant, malapari, weed

Abstract

ABSTRAKPenanaman talas beneng (Xanthosoma undipes K.Koch) di bawah tegakan hutan rakyat dapat berkontribusi bagi ketahanan pangan, peningkatan pendapatan masyarakat dan perbaikan kualitas lingkungan. Tujuan penelitian ini adalah untuk melakukan evaluasi pertumbuhan talas beneng pada pola agroforestri dan monokultur. Penelitian dilakukan dengan observasi lapangan terhadap 2 (dua) pola tanam talas beneng yaitu agroforestri dan monokultur di hutan rakyat Desa Pagerageng, Kecamatan Pagerageung, Kabupaten Tasikmalaya. Hasil penelitian menunjukkan bahwa seluruh parameter yang diamati berbeda nyata antar kedua pola tanam. Tinggi tanaman, lebar daun dan panjang daun talas beneng pada pola agroforestri sebesar 107,3 cm, 43,6 cm dan 64,7 cm, pada pola monokultur sebesar 42,4 cm, 19,8 cm dan 31,4 cm. Pertumbuhan talas beneng yang lebih tinggi pada pola agroforestry mengindikasikan bahwa jenis ini cukup potensial untuk dikembangkan dibawah tegakan pohon. Kata kunci: agroforestri, monokultur, talas beneng, pertumbuhan, produktivitas

Abstract

ABSTRACT                                                                                    Development of manglid private forests is experiencing challenges with sucking insects attack of Urostylissp. which inhibits the growth of manglid until death. This study aims to identify the attack percentage and attack intensity of the sucking insects on monoculture, manglid agroforestry, and control efforts. The methods used were exploration and experiment. The results showed that the attack percentage of Urostylis sp. on monoculture and agroforestry patterns were 59% and 53% respectively. Attack intensity of Urostylis sp. on monoculture and agroforestry pattern were 55% and 31% respectively. Pests control using a biological insecticide of 1 g/l Bacillus thuringiensiseffectively caused mortality up to 95% while the botanical insecticide using 5 ml/l  Azadirachtin was more effective as a repellant. Pest control of Urostylis sp. using 1 g/l B. thuringiensis can be done during the early dry season.

Abstract

Dried nampu leaves have become an export commodity as raw materials for the pharmaceutical, cosmetic, and herbal cigarette industries. However, the massive exploitation of nampu leaves in their natural habitat in forest areas has raised concerns that it could disrupt forest sustainability. Therefore, financial analysis is needed to find out whether this business could be expanded or not.  This study aims to examine the feasibility of processing nampu leaves into dried chopped leaves, the challenges and the prospects for its development. We conducted a case study on a nampu leaf processing business group in Cihaurbeuti Subdistrict, Ciamis, West Java. Data was collected through in-depth interviews and field observations. The results showed that the nampu leaf processing business was feasible because of the availability of resources, an easy process and a relatively short payback period as indicated by the R/C value of 1.17 and BEP production of 2,596.15 kg and BEP sales of IDR38,942,307 which can be achieved in less than 1 year. The challenges of this business are the availability of raw materials, marketing guarantees and forest sustainability. Government assistance is very important in supporting the sustainability of this business.

Abstract

Tisuk (Hibiscus macrophyllus Roxb.) is one of fast growing tree species widely planted in private forest mainly in Java Island. However one of the weaknesses of tisuk wood is the low durability which is categorized as durability class of III/IV. This paper studies the durability improvement of tisuk wood using Boric Acid Equivalent (BAE) with cold immersion method. The tisuk wood samples were taken from a private forest in Sukamulih Village, Sariwangi Sub-district, Tasikmalaya Regency. The treatments applied were wood thickness (thickness of 2.5 cm, 5 cm, 7.5 cm and 10 cm); immersion time (3 days, 5 days and 7 days); and two preservative concentration (5% and 10%). Each treatment was replicated in 10 specimens (total of 240 specimens). The parameters measured were the retention and penetration of preservative solutions. The analysis of variance shows that the retention of the preservative solutions was significantly different for the wood thickness treatment but it was not significant for other treatments (immersion time and preservative concentration). Meanwhile, the penetration of the preservative solutions was not significantly different for all of the treatments. The retention and penetration of the preservative solution fulfilled the minimum standard required by Indonesian National Standard for wood preservation in all treatments. Based on the analysis, the wood preservation method recommended for tisuk wood using boron and boric acid solutions is 3 days of duration of immersion with concentration of 5% for all of wood thickness treatments (2.5 cm, 5 cm, 7.5 cm and 10 cm).
