Abstract

This study aims to determine the good biopotting composition for the growth of sengon seedlings and its resistance in nursery. This research was conducted at the BPDASHL Kahayan nursery and at the UPT Integrated Laboratory of the University of Palangka Raya. The research method used was Completely Randomized Design (CRD) with treatments: 30% clay + 70% peat soil (L1Gm1), 30% clay + 70% sawdust (L1Gr1), 30% clay + 70% dry compost (L1Kr1 ), 50% clay + 50% peat soil (L2Gm2), 50% clay + 50% sawdust (L2Gr2), 50% clay + 50% dry compost (L2Kr2) where each treatment was repeated by 10 times. The data collected and analyzed were the growth of sengon seedling height (cm), sengon seedling diameter (mm), sengon seedling quality index and the level of damage to biopotting. The results of this study indicate that the best treatment for height and diameter growth is composition of 30% clay + 70% dry compost (L1Kr1). This treatment also produces the best Seedling Quality Index. Meanwhile, the biopotting composition that produces the best resistance is 30% clay + 70% saw dust (L1Gr1).

Abstract

Tujuan dari penelitian ini adalah mengetahui dan menganalisis pengaruh daya laser CO2 terhadap warna dan preferensi konsumen dari produk papan parikel. Papan partikel tersebut dilakukan pengukiran dengan menggunakan daya laser 2,5 Watt, 5 Watt dan 7,5 Watt. Perubahan warna diuji dengan sistem CIE-LAB dan preferensi konsumen dilakukan dengan wawancara responden. Hasil pengujian kecerahan (L*), kromatisasi merah/hijau (a*) dan kromatisasi kuning/biru (b*) mengalami penurunan seiring dengan naiknya daya laser, sedangkan nilai perubahan warna (∆E*) memperoleh nilai > 12 yang berarti warna berubah total. Preferensi konsumen menunjukkan bahwa laser dengan daya laser 7,5 Watt memiliki hasil yang lebih besar, yang artinya lebih disukai oleh konsumen. Hasil tersebut memperoleh kesimpulan bahwa tingginya daya laser yang dipakai untuk pengukiran menyebabkan warna yang dihasilkan oleh produk papan partikel menjadi lebih gelap, hal tersebut menambah minat para konsumen dalam membeli produk.

Abstract

Non-timber forest products (NTFPs) for palm plantations have high economic potential for farmers. The productivity of sap on sugar palm plants is very important to study to determine policy directions that can help the community's economy. Sugar palm plants in the productive age group are only 38 stems with the highest level of production occurring in the 5-8 year age class with the production of sap per tree reaching 47,727 liters by the year. The total productivity of sap produced in one year reaches 43,908,573 liters. Sugar palm plants can be tapped since the age of 5 years and have been productive at the age of 7 years. The economic potential obtained by palm farmers in one year is Rp56.071.061 or Rp4.672.588/month. However, there are fewer productive sugar palms than post productive plants, so farmers need to regenerate plants to increase the yield of existing sap.

Abstract

Sugar palm (Arenga pinnata) is a palm plant that has many benefits but has a hard seed coat and is impermeable to water and oxygen. besides that the palm skin also contains ligin so that the seeds is dormant. Proper scarification technique needs to be done to overcome the dormancy in the palm seeds. Fermentation and deopercolation are scarification methods used to break the dormancy period of palm seeds. The purpose of this study was to determine the scarification method to break the dormancy period of sugar palm seeds by using the percent germination parameter. Fermentation was carried out with cow dung tested for 0.2, 4, 6 weeks. While deopercolation was carried out using sandpaper with a paper roughness level of 80, sanding was carried out on the backs of the palm seeds where the roots would appear. Each treatment was repeated three times in each replication using 15 sugar palm seeds. This research was conducted for 2 months in the greenhouse of the Faculty of Agriculture, University of Lampung. The results showed that the best treatment was the fermentation method for 6 weeks combined with deopercolation with a germination percentage value of 82.22%. The use of abrasive paper for the deopercolation method needs further research, the results of this study can be used in the practice of sugar palm cultivation

Abstract

Sustainable forest management as a complete ecosystem has problems that are often detrimental to the economy and ecology, one of which is disease. Some examples of pathogens that attack forestry plants are Rhizoctonia sp. and Fusarium sp. which cause leaf blight. An alternative to control it is using chitinolytic bacteria as biological agents which are cultured in fishery waste media. This research aims to (1) determine the appropriate formulation of fish waste as a growth medium for chitinolytic bacteria and (2) determine the ability of the antagonist test of chitinolytic bacteria in inhibiting the growth of pathogenic fungi causing leaf blight. The steps used consisted of (1) media preparation, (2) bacterial and fungal rejuvenation, (3) bacterial culturing in fishery waste media, (4) Bacillus subtilis and Pseudomonas aeruginosa antagonist tests against the fungus Rhizoctonia sp. and Fusarium sp., and (5) primary data analysis using OpenCFU and SAS applications. The result shows that the best fish waste formulation for growing chitinolytic bacteria was CR:KU:SI (2:1:1) with an average colony of 285 colonies for B. subtilis and 202 colonies for P. aeruginosa. The results of Anova analysis showed that the media formulation treatment has a significat effect on the growth of B. subtilis and P. aeruginosa bacterial colonies. The results of the in vitro antagonist test shows that the growth of Rhizoctonia sp could not be inhibited by the bacterium Pseudomonas aeruginosa. While the results of the antagonist test on Fusarium sp. shows if the P-value obtained is p>0,05, which means the data is not normally distributed or there is no effect of the application of B. subtilis and P. aeruginosa bacteria in inhibiting the growth rate of Fusarium sp.

Abstract

Cikeruh Sub-Watershed is an area that has occurred a lot of land-use conversions, for residential and industrial, especially in the Jatinangor and Rancaekek districts. The annual sediment rate that occurred in 1994-2001 reached 100 tons/km2. Characteristics of the biophysical carrying capacity of Cikeruh Sub-Watershed need to be studied to provide an overview of the Sub-Watershed conditions. Using the SWAT model in this study is very effective and efficient in predicting the impact of land management practices on the carrying capacity of the Cikeruh Sub-Watershed. The purpose of this study is: (1) to identify biophysical characteristics, (2) determine the carrying capacity of Sub-Watershed, and (3) provide recommendations for the best land-use scenario in Cikeruh Sub-Watershed. The parameters analyzed are land and hydrological characteristics based on Permenhut Number P.61/Menhut-II/2014 about Monitoring and Evaluation of Watershed Management. The statistical analysis shows that the performance level of the model in the calibration and validation process is satisfactory with the values of NSE (0,57) and R2 (0,62) in the calibration process and NSE (0,46) and R2 (0,51) in the validation process. The biophysical characteristics of the Cikeruh Sub-Watershed have good criteria are KRA, KAT, and IPA, while poor criteria are PLK, PPV, erosion index, sediment loads, and flood. The carrying capacity of the Cikeruh Sub-Watershed is the moderate criteria. The best scenario to solve these problems is scenario 2 by converting agriculture to the forest by 17%, rice to the forest by 3%, and rice to agriculture by 7%.

Abstract

Management of Non-Timber Forest Products (NTFPs) by the people of Hanura Village, Pesawaran Regency, Lampung in the Wan Abdul Rachman Forest Park is still limited to plants such as durian, Tangkil, areca nut, sugar palm, candlenut and other top canopy plants that cannot be relied for support basic household needs. On the other hand, the potential for understorey tree stands in forest areas has not been widely utilized for seasonal or commercial undergrowth species, due to farmers allegedly have not known yet about species of food crops which economically viable under stands. Meanwhile, farmers only know food crops for instance rice, corn, soybeans, cassava, sweet potatoes which can not be planted in forest areas. The effort to alleviate poverty and improve the welfare is through the development of porang plants which can be planted under mixed forest stands. For this reason, it is necessary to introduce and train porang to equalize their perceptions. The research method using Focus Group Discussion (FGD) and distributing questionnaires to 15 farmers. The results showed that the respondents in general were familiar with the porang plant, although not deeply. However, not many people know about porang development, so they are motivated to learn more, starting from nurseries, planting to harvesting.
