Abstract

Four Eusideroxylon zwageri Teijsm. & Binn. varieties had been described. A study on growth performance of one-year old seedlings of E. zwageri varieties had been conducted to study the comparison of shoot growth performance and survival among E. zwageri varieties.  The varieties were exilis, grandis, ovoidus, and zwageri. The study was conducted in Jambi, Indonesia for one year using complete randomized design. Four E. zwageri varieties were used as factor with 6 replications. Each consists of 6 seedlings therefore, the total number of seedlings were 144.  The results showed that survival and shoot growth performance of E. zwageri seedlings were significantly different among varieties. Stem height of E. zwageri seedlings was significantly different among some varieties. The results related to stem diameter showed different characteristics among E. zwageri seedlings, zwageri variety had the biggest diameter. It was significantly different from ovoidus and exilis, but not significantly different from grandis. The differences among E. zwageri seedlings in shoot dry weight parameter were identical to the parameter of stem diameter. The lowest value of branch angle belonged to zwageri. Based on Duncan multiple range test, it was significantly different from other varieties except grandis. Generally, zwageri shows the best growth performance among seedlings of E. zwageri varieties.Keywords: growth performance, ironwood, seedlings, varieties

Abstract

Economic crisis and various economic recovery policies issued by government lead tomore dynamic and fluctuative prices of foodstuffs and agricultural inputs since mid 1997.During the peak period of the crisis food prices at retail market increased at higher rate, about3 to 25 times of price growth before crisis, particularly for the low price foodstuffs. Thismeans that the crisis tends to cause higher impact on food consumption of low incomehousehold. To overcome the crisis various trade policies on food and agricultural inputsissued by government so that the rate of growth of food prices become lower, in other word,favorable for food consumer. Those policies however were unfavorable for farmer’s incomeincrease because due to policies on inputs trade the ratio of food prices to inputs pricesdecreased with increasing rate. The situation was more difficult for future agriculturedevelopment, which more focused on income increse instead of production increase, becausein addition to unfavorable prices the crisis also lead to increase of number of people involvedin agricultural sector about 3.56 million people or 9.9 persen. In order to support agriculturedevelopment, accordingly, reorientation and reorganisation of food trade policies for riceparticularly is required.

Abstract

The scarcity of land, especially sawah land is one of problems that cause to achieve riceproduction more difficult for producing the staple food. Because of that, the Indonesianstatus shifted from self sufficient to rice importer. The objective of this paper is to seekthe size of sawah land conversion and how is the implication to the rice production, andhow is the Government effort to control the sawah land conversion. By tabulation andsimple mathematic approach, the result showed that during 18 years 26, 9 thousandhectares each year, occurred net sawah conversion in Java. During that period, netaccumulation of rice losses was about 40, 6 million ton or 2, 2 million ton per year as animpact of sawah land conversion. The government effort to control sawah landconversion just conducted by law enforcement approach, which is still looking for thebest way. So, the effectiveness of law enforcement to control sawah land conversion isstill relatively low.

Abstract

During two last decades food trade in the world market was shift to horticulturalproducts such as fruits and vegetables. Household consumption of the products also tends toincrease in domestic market due to the increase of income per caput, induced by economicgrowth. The two tendencies reveals that market of horticultural products will increase in thefuture both in domestic and world markets, and barier of entry to the market will beeliminated in the era of trade liberalisation. It is true that Indonesia had a surplus in the tradeof horticultural products, comes particularly from fruits trade, but this surplus is continuouslydecreasing resulted from decrease of competitiveness of local agribusiness compared withthose from Africa and Southern America countries particularly. To increase competitivenessof local agribusiness, future development of horticulture sector should be focused on threeefforts : (1) Development of vertically integrated agribusiness so that horticulturalagribusiness has capability to respond market demand effectively. This effort can beimplemented through development of partnership business system between input trader,farmer and output trader. (2) Price stabilization of horticultural products, which can be takenby establishment of regional agribusiness institution across producer regions. The main taskof the institution is to regulate supply quantity of overall producer adjusted to marketrequirement. (3) Facilitation of post harvest infrastructure to farmers in order to retarddegradation of product quality and to improve bargaining position of farmers in the priceformation at producer market.

Abstract

Seed and seedling is one of main factors in determining the product of horticultural crops. Theuse seed production on horticultural crops, could be produced by government institution orprivate sector. In the last 21 years (1980 – 2001) the government has released 183 improvedvariety of vegetables, including 26 red onion, red chili, cabbage and potato. These number ismuch Owen compared to number of improved variety of crops. For instance 105 newimproved varieties for rice, 50 varieties for corn and 33 varieties for soybean. The role ofprivate sectors on the horticultural seed is much more dominant to the high demandcommodities and cannot be produced by the farmers it can be seen on the production of redchili seed compared to three other commodities. The performance of seed on the levelconsumer, represented by the farmers in the area production central, namely red onion, redchili in the central Java Province, and potato and cabbage in North Sumatera Province. Thefindings of the study are : the farmers are influencing by the group on the selection of seed tobe use, the role of field extension worker is very limited, the seed has been use by the farmersbefore introducing by government, at any planting time the farmers not always use a newseed, even there are some farmers never used improved variety of potato.

Abstract

This paper describes a program called ?Quality Improvement on Intensification (QII)? especially in relation with it?s: 1) implementation, 2) adoption - diffusion and 3) effect on the rice production. The research was conducted in the District of Pekalongan and Pemalang ? Central Java, in which from each District, two villages were chosen as the sample, one village represented the succeed of QII and one unsucced QII village. The data were collected in October 2002 from ten QII cooperators? farmers and ten no cooperators? farmers in one village, therefore the total respondent farmers from Central Java were 80 farmers. The data were analyzed qualitatively and presented descriptively. The results show that: 1) the implementation of the program was not follow the QII?s rules namely: a) the selected locations were in the villages which is already received program intensively instead of the villages which never received intensification. b) The selected farmers were according to their ability in returning the credit instead of the land holding. c) The socialization of QII program only emphasized the technical aspect, not included the social aspect such as the empowerment of the farmers. 2) All the cooperators and non-cooperators farmers (100%) were familiar with the suggested technology but only technologies which were not increase the farming input such as planting distance and the number of plant which has been implemented by 100% farmers. Farming pattern was not implemented because not suitable with the water availably (Pekalongan) and capital (Pamalang). Technology with high capital such as balance fertilizing only implemented by 70% of cooperator farmers and 32% of non-cooperator farmers. , complicated technology such as organic fertilizer making and expensive technology such as post harvest were never practiced by both cooperators and non-cooperators farmers. QII program was 16% increase the rice production of the cooperator farmers and 11% of non-cooperator farmers with the benefit of each 38% and 24% from the total output; however this achievement was decrease when the program had finished.

Abstract

Phenomena of paddy field conversion to non agricultural purposes has been worried,especially conversion in Java. Paddy fields have multi functions that related to many aspects,such as economic, socio-cultural, ecological environment, amenity, and national food security.Massive conversion of paddy field will caused externalities. Inadequate appraisal of Paddyfield multi functions become one of determinant factors for speeding up process of paddy fieldconversion. Outcome of this research indicate that both village society and regionaldevelopment stake holder give less appreciation to other elements of Paddy field multifunctions rather than its capacity as food stock and labor absorption. Farmers Appreciation forits function as environmental conservation and intrinsic values of paddy field are varied.Farmers aged, education, and the wide of land cultivation tend to affect positively. Meanwhile,the differences of region characteristic tend to affect the differences of farmers opinion incausal factor of environmental degradation.

Abstract

ABSTRACTThe incidence of heart failure has increased in recent decades. Despite recent achievements in the treatment of heartjinlure, the prognosis is still poor. Hypertension is one of the most important risk fators jbr the klopment of heart failure. Mechanisms which maintain normal function of the heart in the short term in hypertension have longer term deleterious epcts. These include Ieft ventricular hypertrophy and chronic activation of the a d m g i c and renin-angiotensin systems.Beta - blocking agent is one of the most promising helopments in the treatment of heart failure, which is capable in blocking the a d w g i c system and, to some extent, the reninngiotensinsystems. One of the most promising helopmenfs in phamological treatment of heart fhilure is the results obtainedfrom the use of beta-blocking agents. ThewfbTe these agents me m y important in treating hypertension, both jbr the prevention of the helopmenf of abnormalities and fbrreversing established LV dysfunction and hypertrophy. Trials in the management of heartjinlure had shown that these agents prevented progressioe myocardial dysfunction, prevented and reversed remodelling and impw~ed systolic function. However, more studies are still needed, including direct comparisons of different agents.KEYWORDS Ieff ventriculm hyperfroply; heartfailure; beta blockade; remodelling

Abstract

Sructural Equation Model (SEM) merupakan penggabungan teknik analisis faktor dan sidik lintas. Ada dua pendekatanpada SEM. Pertama, model struktur koragam, dikenal dengan metode LISREL (Linier Structural RELations), yang mempunyaiasumsi-asumsi peubah pengamatan menyebar normal ganda dan ukuran contoh relatif besar (n>100). Kedua, metode kuadratterkecil parsial, dikenal dengan metode PLS (Partial Least Squares), yang mempunyai asumsi-asumsi bebas sebaran (softmodeling), dan ukuran contoh tidah harus besar. Kedua metode terdebut diterapkan pada pemodelan Kualitas mahasiswa. Karenadata tidak menyebar normal ganda dan ukuran contoh pada tulisan ini n<100(n=71) sehingga metode PLS lebih tepat digunakandari pada metode LISREL.
