The utilization of land under tree stand in teak forest has been widely applied by Perhutani as a means to maintain the quality of teak tree and to give additional income to people living around the teak plantation. In general, the utilization of land under tree stand is by planting crops for limited duration. One of the crops planted under teak stands is papaya that is planted together with teak seedlings until 2 years. This study aims to analyze the feasibility of papaya cultivation under teak stands in Purwaharja Village, Banjar City. The analysis tools used include NPV (Net Present Value) and BCR (Benefit Cost Ratio). The results of this study show that the papaya cultivation under teak stands give NPV of IDR 20,072,606.- and BCR of 2.89. Therefore, the cultivation of papaya under teak stand is feasible to conduct.

This study aims to determine the provenance of sengon that is resistant / tolerant to tumor rust attack in Panjalu District, Ciamis Regency. The experimental design used in developing a resistance test plot was a completely randomized block / RCBD (Randomized Complete Block Design). There were 12 provenances used in this trial, consisting of 25 treeplot (5 x 5) from Papua, with 4 blocks as replications and spacing of 2 mx 3 m.. The results showed that provenance differences did not significantly affect all 2-year-old sengon growth parameters. The highest survival rate was achieved by Nifasi provenance (95%) and the lowest was achieved by Elaigama provenance, Hobikosi (67%). The average height ranges from 3.17 meters (Meagama) to 5.51 meters (Maidi, Nabire), while the average stem diameter ranges from 3.27 cm (Pyramid, Muai) to 6.72 cm (Maidi, Nabire ) Up to 2 years old, there were 3 provenances of sengon from Wamena which were tolerant of tumor rust attack, namely from Waga-Waga, Holima and Hobikosi. Meanwhile, attacks on 9 other provenances were generally still in the low level, i.e. the highest Disease Incidence and disease severity were Wadap and, Menawi provenances by 20.8% and 43% respectively. These provenances need to be evaluated continuously to find out the provenances that are resistant to gall rust disease over one rotation period as genetic material for future sengon forest development.

Differences in access of natural resources between men and women is one of the causes of gender unequality.  This condition may have an impact on the lack of control, benefit, and participation of women on farming activities.  This study aims to analyze the gender relation pattern in private forest management in Banyumas and Banjarnegara Districts..  Data were collected by using questionnaire, interview with farmer (men and women) and farmer groups with Socio Economic and Gender Analysis (SEAGA) instrument. Total respondents were 64 private forest farmers who were randomly selected. Data were analzsed by tabulation, percentage dan Equality adn Equity Index (EEI). The results showed that acces in private forest management were dominated by men  e.g acces on land, crops cultivated, education, training, extension services, capital, credit, equipment, nursery, fertilization, cropping pattern, and pest and disease control. In contrary, women were more dominant in  post harvest processing, and marketing activities. In Banyumas District, women control were dominant in marketing, while in Banjarnegara Distric, there was no dominance in both resources and stage activities but  access and control were  undertaken jointly between men and women in crops cultivation, watering, fertilization and marketing.The pattern of gender relations in general was more dominant both in terms of resources and the stages activies of private forest as indicated by EEI value tha is less than 0,5.
男女在获取自然资源方面的差异是造成两性不平等的原因之一。这种情况可能对妇女缺乏对农业活动的控制、利益和参与产生影响。本研究旨在分析Banyumas和Banjarnegara地区私人森林经营中的性别关系模式。采用问卷调查、对农民(男性和女性)和农民群体进行访谈,并采用社会经济和性别分析(SEAGA)工具收集数据。调查对象为随机抽取的64名私营林农。数据采用制表法、百分比法、平等和公平指数法(EEI)进行分析。结果表明,在私人森林经营中,土地、作物种植、教育、培训、推广服务、资金、信贷、设备、苗圃、施肥、种植方式和病虫害防治等方面的获取以男性为主。相反,妇女在收获后加工和营销活动中占主导地位。在Banyumas区,妇女在销售方面占主导地位,而在Banjarnegara区,在资源和舞台活动方面都不占主导地位,但在作物种植、浇水、施肥和销售方面,男女共同获得和控制。从资源和私人森林活动的阶段来看,一般的性别关系模式更占优势,EEI值小于0,5。

Generative propagation was needed as one of efforts in developing jamblang as a medicinal plant. This study aims to improve the percentage and germination rate of jamblang seeds through pre-germination and sowing media treatments. The combination of treatments were (1) soil (T) x water (AB), (2) soil (T) x coconut water (AK), (3) soil (T) x control (without soaking treatment) (K), (4) sand (P) x water (AB), (5) sand (P) x coconut water (AK), (6) sand (P) x control (K), (7) mixed soil-sand (TP) x water (AB), (8) mixed soil-sand (TP) x water (AB), and (9) mixed soil-sand (TP) x control (K). The results revealed that the treatments of sowing seeds with mixed media soil + sand and pre-germination treatments by soaking the seeds for 12 hours in coconut water gave the highest percentage (70%) and germination rate (4.96%). Percentage of germination more than 50% only can be reached by the seeds that sowed on mixed soil + sand with pre-germination treatments soaked in coconut water for 12 hours and in water for 12 hours. The improvement in the percentage and germination rate of jamblang were achieved by using mixed sowing media soil + sand and pre-germination treatment by soaking in coconut water.
繁殖繁殖是将混香开发为药用植物的努力之一。本试验旨在通过预萌发和播种剂处理,提高jamblang种子的发芽率和发芽率。处理组合为(1)土(T) ×水(AB),(2)土(T) ×椰子水(AK),(3)土(T) ×对照(未浸泡处理)(K),(4)砂(P) ×水(AB),(5)砂(P) ×椰子水(AK),(6)砂(P) ×对照(K),(7)土-砂(TP) ×水(AB),(8)土-砂(TP) ×水(AB),(8)土-砂(TP) ×水(AB),(9)土砂混合(TP) ×对照(K)。结果表明,土砂混合播种法和椰子水浸泡12 h的种子萌发前处理的种子萌发率最高(70%),发芽率最高(4.96%)。种子只有在混合土+砂上进行发芽前处理,在椰子汁中浸泡12小时,在水中浸泡12小时,才能达到50%以上的发芽率。采用土+砂混合播种剂和椰子水浸泡发芽前处理,可提高jamblang的发芽率和发芽率。

The high demand of medicinal plants with limited agricultural land availability can be solved by the utilization of land under forest canopy through applying agroforestry. This study aim s to assess the effect of different varieties of ginger and different shading intensities of pine ( P inus merkusii ) on the productivity and quality of ginger. The design used was a split plot design consisting of 3 replicates with an area of 100 m 2 for each plot and with spacing of 50 x 50 cm. The main plot is the light intensity treatments, i.e. 50-58% (age class I I), 68-77% (age class I) and 87-92% (poor increment), whereas the sub plot is the varieties of ginger i.e.: small white ginger (emprit), large white ginger (gajah) and red ginger. R esults showed that the light intensity does not significantly affect the percentage of growth, moisture content, volatile oil, fiber, starch and ash. Varieties of ginger significant ly a ffect the percentage of growth, h e igh t growth and weight of rhizome, but do not significantly affect the moisture content, volatile oil, fiber, starch and ash . The a verage yield of each variety of ginger is 5.54 tons/ha , 8.38 tons/ha and 6.7 ton /ha for small white ginger, large white ginger and red ginger , respectively. Agroforestry of ginger plant under pine stand can be done to improve land productivity, especially in poor stand increment .

Teak and polynesian arrowroot is a new pattern of agroforestry to support food security of communities around forests in coastal areas. The presence of polynesian arrowroot under teak stands is not only expected to be food sources but also to provide ecological benefits for biodiversity, especially soil macrofauna. The study aims is to determine the diversity of soil macrofauna in teak and polynesia arrowroot agroforestry patterns. The study was conducted in Garut Regency in April 2017. The method used in this study was monolithic technique and analyzed by calculating diversity and richness index. The object was an agroforestry demonstration plot with three polynesia arrowroot spacings under 7-years-old teak stand and monoculture teak. The results showed that there were 5 soil macrofaunas in teak and polynesian arrowroot agroforestry which are from five families and five orders. The dominance order was coleoptera with Important Value Index (IVI) = 133.93% -157.78% and opisthophora with IVI = 103.51%. The diversity and richness of soil macrofauna in teak and polynesian arrowroot agroforestry patterns is low (H '= 0.28-0.55; R' = 0.87-1.48). Although agroforestry cultivation is carried out intensively, there is no difference in the diversity of soil macrofauna when compared to teak monoculture.
柚木和波利尼西亚竹是支持沿海地区森林周边社区粮食安全的一种新型农林复合模式。柚木林下存在的波利尼西亚竹根不仅是一种食物来源,而且为生物多样性,特别是土壤大型动物提供了生态效益。研究目的是确定柚木和波利尼西亚竹复合农林业模式下土壤大型动物的多样性。该研究于2017年4月在加鲁特摄政进行。本研究采用整体技术,通过计算多样性和丰富度指数进行分析。研究对象是一个农林业示范地块,在7年柚木林下有三个波利尼西亚针叶树间距和单一柚木。结果表明,柚木和波利尼西亚竹复合农林业中存在5种大型土壤动物,分属5科5目。优势序为鞘翅类,重要价值指数(IVI)为133.93% ~ 157.78%,其次为蚜蝇类,IVI为103.51%。柚木和波利尼西亚竹复合农林业模式土壤大型动物的多样性和丰富度较低(H′= 0.28-0.55;R' = 0.87-1.48)。虽然农林复合栽培是集约进行的,但与单一栽培相比,土壤大型动物的多样性没有差异。

Although agroforestry cultivation is carried out intensively, there is no difference in the diversity of soil macrofauna when compared to teak monoculture.","PeriodicalId":120721,"journal":{"name":"Jurnal Agroforestri Indonesia","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132644249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
