Abstract

The aim of the research is to evaluate the effectiveness of micro fertigation system and application of cows fermented urine (uriferm) for chili (Capsicum annum sp.) Cultivation.  The micro fertigation system with 0.5 mm inside diameter micro-tubing is used to control the flow from outlets along lateral.  The lateral with 5/16 inch inside diameter is made of soft PVC hose.  The result of the research showed that the micro fertigation system is running well. Randomized block design with four replications are used for the field experiment.  There are four treatments i.e. conventional culture by watering can (A), uriferm fertigation (B), non uriferm fertigation (C), and Hartus formula fertigation (D).  The laboratory analysis showed that the properties of uriferm increase in composition compared to non uriferm and used successfully as nutrition.  The micro fertigation system showed better result compared to the watering can on variable observation of plant and root development of chili.  The field experiments showed that the micro fertigation system significantly reduced volume of water used by 49.5% and raised chili yield by 61.2% compared to watering can.  The uriferm fertigation (B) showed better result compared to other treatments on wet weight of chili and water productivity.  The total income from 390 m2 irrigated land with micro fertigation system was about Rp 2,961,700,00/season and  feasible to apply with B/C ratio =  1.51, IRR value = 27.49% and NPV = Rp 387,413.83 at discount rate 9% per annum.   Key words: micro fertigation system, uriferm, chili, water productivity, small plots

Abstract

Sustainable agriculture development requires a high quality and proper land management in order to promote high farmer’s income and to prevent natural  resources degradation. This research was conducted in Nopu sub-watershed, a sub sub Gumbasa watershed, Central Sulawesi Province. The erosion and surface run off were observed by placing erosion plots on various ages of cocoa land uses (monoculture and agroforestry), whiles the soil quality indicators were observed by analyzing the physical and chemical properties of soil samples, which were collected from various  ages of cocoa land use. The soil profile  permeability and soil surface coverage were directly observed on the field. Production and farmer’s income of various cocoa land use systems in Nopu watershed were collected by using questioners.  Sustainable management of cocoa (monoculture and agroforestry) was formulated by using various scenarios. Results of the study showed that 1) forest conversion into cocoa land use decreased soil quality degradation, tended to increase soil erosion and run off; 2) to establish a sustainable cocoa farming system in Nopu watershed, there should be practiced a proper and equilibrium fertilization, application of adequate soil and water conservation techniques such as mulching and construction of ditches closed (rorak) and  ridges (sengkedan).   Key words:  cocoa, erosion, farmer’s income, forest conversion, soil quality

Abstract

The textile industry has a role in the non-oil export of Indonesia. Cotton is the main raw material of textile and products of textile (TPT) in Indonesia. Ninety-nine percent of the domestic needs of cotton is imported from Australia, America and China. The Pondok Pesantren Darussalam Co-operation (Koppontren) has been one of the developers of rami fiber since 1998. The objectives of this study is to assess the description of rami fiber, the economic prospect and its development strategy, as well as to identify internal and external factors influencing its production strategy as the alternative raw material of the textile industry, in order to decrease dependency on import, which has become very high and difficult to obtain. The methods of analysis used were a technical survey using questionnaire, a descriptive analysis, a ratio analysis, and the Strengths, Weaknesses, Opportunities and Threats (SWOT) qualitative analysis. From the descriptive analysis it has been found that (1) the raw material of rami cotton has some advantages, such as resistant to bacteria and fungi, better water absorption, a stronger pull, and better social economic impact; (2) The ratio analysis of the financial report is based on (a) the liquidity rate, covering the Current Ratio (CR) of 1.57, the Quick Asset Ratio (QAR) of 1.41, and the Net Working Capital (NWC) of 0.58; (b) the Solvability Ratio, covering Debt to Asset Ratio (DAR) of 0.08, and the Equity Multiplier of 1.09; (c) the Activity Ratio, covering the Inventory Turn Over (ITO) of 26.7, and the Total Asset Turn Over (TATO) of 0.49; (d) the Profitability Ratio, covering the Profit Margin (PM) of 0.08, the Return on Asset (ROA) of 0.04, and the Return on Equity (ROE) of 0.04; (3) The SWOT qualitative analysis showed the following internal and external factors: (1) Strengths (S): good financial performance and adequate raw material; (2) Weaknesses (W): weak manpower, old production equipment, and simple management; (3) Opportunities (O): availability of market share, product development and government policy; (4) Threats (T): no SNI standard, business competition and low price of imported rami cotton. The analysis resulted in an alternative strategy, such as a combination of (1) “SO”: good financial performance because this has created profit, and availability of raw material for adequate production; (2) “ST”: deciding production cost, and increasing quality of rami cotton; (3) “WO”: development of manpower through training, improvement of production technology, and effectiveness of managerial system in running the business; (4) “WT”: business strategy by focusing on certain grades of products, developing a wider partnership with others, and investing production equipment.

Abstract

Packing made from wood is one of the choices in transporting commodity to protect a product effectively.  In 2002, FAO determined the International Standard for Phytosanitary Measure (ISPM) which is the standard that arranges the quarantine of plants for wood packing used in international trade. In Indonesia ISPM is done by Badan Karantina Pertanian (Barantan). The objectives of this study are to evaluate the feasibility of its Palembang branch, to arrange a suitable marketing strategy and to asses its possible development to become a single entity firm (separate from the main office). The analysis of the study in Palembang showed that this branch office is feasible, with an NPV positive of Rp 928,99 million and an IRR of 26,93% (higher than the capital interest of 14%), and a PBP for 3 year 1 month PBP (shorter than the 4-year credit term).  The IE matrix used shows that the company is in the first matrix position; therefore, the strategy of growth is used. From the SWOT analysis there are 4 alternative strategies such as S-O, W-O, S-T and W-T.  These strategies are formulated into the  marketing  strategy that can be applied based on mixed marketing: (1) product strategy: maintenance of product quality and innovation in the design of production system, to accelerate the production process and to improve productivity using skilled labor; (2) the price strategy: reducing price based on BEP calculation and applying cost efficiency; (3) the location strategy: closer to market and raw material resources and maintaining relationship with distribution channels; (4) the promotion strategy: introducing the company to  potential customers.   Key words: Packing, Phytosanitary, ISPM, Pallet, NPV, PBP, IRR

Abstract

The objectives of this study were (1) to identify the characteristics of DPM-LUEP recipient groups, (2) to identify factors affecting income/profit increase in DPM-LUEP recipients, (3) to evaluate the effectiveness of determining requirement processes, the mechanisms of grouping, the distribution and the return of the funds to LUEP. The method of analysis used were (1) descriptive analysis, (2) profitability analysis, and (3) Focus Group Discussion (FGD). The results of the profitability analysis showed that the factors capable of increasing income/profit for DPM-LUEP recipients were (1) the effectiveness in purchasing the raw materials/unpolished rice (the cycles), (2) the increased purchase of raw materials which eventually increased the outcome of the processed products, (3) the decrease of the total cost to the sale income, especially the efficiency of the total variable cost, and (4) the product stock taking while waiting for the increase of product sale price (rice) in the market. Based on the FGD, the dominant problems were found not only in the process of determining the requirements but also in the mechanisms of LUEP grouping as well as the paying back of DPM-LUEP. The efforts necessary to overcome the problems so as to increase the effectiveness of decision and of DPM LUEP distribution include organization strengthening and group management, service quality improvement, increasing the capability and the number of staff, and support of facilities and services. In addition, it is necessary to cut down the bureaucracy stages in the process of decision making and the distribution process of DPM-LUEP, provide fund reserve through APBD I and II, as well as to propose to the central authority to conduct more comprehensive research on requirement, decision making, distribution and the paying back of DPM-LUEP.   Key Words: DPM-LUEP recipients, paddy/rice, price, decision making

Abstract

Inmation is important to note because it is related to potentialsurface run-08 jlood, erosion, water storage of soil, and stream discharge especially during dry season. However, because the infiltration equation is valid for certain condition of the land measured, it is important to collect infltartion data on all types of soil manually. This research is mainly to evaluate constants of infltration equation formulated by Kostiakov (constants K and n) and Philip (constants C and D) in relation with initial soil water content. The measurements are on vegetated soil and bare soil.
