Abstract

Water Table Fluctuation in Tidal Lowland for Developing Agricultural Water Management Strategies (MS Imanuddin, E Armanto, RH Susanto and SM Bernas):The research objective is to evaluate the water status in the tertiary block of tidal lowland for developing water management strategies and cropping pattern for food crop agriculture. The research was conducted in tidal lowland reclamation areas of Delta Saleh South Sumatera. The methodology used in this research was survey and monitoring. The result showed that the study area has a potential of acid sulphate soil which is indicated by phyrite layer at 60 cm below the soil surface. Variation of water table was very high in the range of 0-2 cm at rainy season and it was drop up to 90 to 100 cm below soil surface at dry season. This conditions result in the soil oxidation and the pH drop up to 2.5-3.5 (very acid). Analysis of water surplus and deficit during one year period was calculated by surplus excess water under 30 cm (SEW-30) and showed that the area study was experienced water deficit. Analysis of groundwater effect on soil moisture content showed that the critical water level was in 60 cm below soil surface. The soil moisture content at this point in the root zone was dropped into the wilting point level. It means that the water availability for crop water requirement is inadequate. For sustainable agriculture in the area study, the water table should be maintained in 50-60 cm below soil surface. Therefore, the recommendation of water management strategies in the study area is water retention in combination with control drainage system.

Abstract

The objective of the study was to develop the water management operational plan at tertiary blocks for the growth of rice and corn.  Study was conducted at reclaimed tidal lowland area which was located at Primer 10, Delta Saleh.  This area was classified as a C-typhology land (dry).  The methods of the study were survey, field measurements, computer simulation, and field action research.  Study stages were consisted of survey and monitoring, water status evaluation, water management scenarios design, model simulation, and model adaptation.  Computer model of DRAINMOD had been used to estimate the water table status and to design water table control operation at tertiary blocks.  Simulation results showed that the model worked properly which was indicated by root mean square error of 1.45 cm, model efficiency of 0.97, and correlation coefficient of 0.84.  Model adaptation for dry land condition (C-typhology) showed that the best scenario was land utilization pattern of rice-corn.  This paper presented monthly water management operational plan for rice crop in first cropping season (CS1) during November-February period and for corn crop in second cropping season (CS2) during May-August period.  Results of computer simulation and field study showed that the main objective of water management in this area was water retention in combination with land leaching.

Abstract

The primary key to successful agricultural cultivation is maintaining the groundwater level to fulfill crop water requirements, particularly during the dry season. Field study was conducted in Tidal reclamation area of section 25 at Sugihan Kanan, Bandar Jaya Village, Air Sugihan, Ogan Komering Ilir District of South Sumatra.  The DRAINMOD computer model was used to simulate water levels in dry and wet climatic conditions. The principal measured parameters are soil hydraulic conductivity and drain spacing, as well as daily rainfall data. The simulation results showed that the research area belongs to the rainfed type, and the main objective of water management is to retain water and determine some efforts to increase the groundwater level through pump irrigation in the dry season. The application of pump irrigation was applied to the plant entering the generative phase. The pump irrigation was provided to distribute water into the quarter and worm (micro) channels. The effect of this application caused the groundwater level to approach about 30 cm below the soil surface, while groundwater level in areas without pump irrigation facility was in the range of 50-60 cm. Besides efforts to increase the water table, liming is still required in order to increase production. Lime application of 1 Mg ha-1 had a significant effect on increasing production. Corn production with this treatment could produce 5 Mg ha-1, while non-treated land areas only produce 2-3 Mg ha-1.

Abstract

Tidal lowland productivity in type C is still low. Most of them have only been able to cultivate rice twice a year. The third cultivation of corn often fails due to a lack of water. The research objective is to determine an operational model for water management in the field for maize cultivation at several planting times. Model area is conducted at a tertiary block of reclaimed tidal lowland, Telang Jaya Village Primer 8 Delta Telang I, of  Banyuasin District. There are three planting times treatments: the fourth week of April, the second week of June, and the first week of July, 2021. A water management model was applied to control the drainage system, in which the water level in the tertiary channel is maintained at a depth of 50 cm. When groundwater drops below 70 cm, and there is no rain, pump irrigation is provided. Results of the field experiment showed that the maize crop showed similar growth quality at each phase. Land with a planting period of June and July still requires water addition using pump irrigation. It was applied on 14th and 18th August. Moreover, the maize cultivated at the end of April did not require pump irrigation. All treatments have generally similar production with an average magnitude of 8.0 Mg ha-1. The highest production is 8.73 Mg ha-1, which is planted in the first week of July.

Abstract

This study examines the financial feasibility of different replanting patterns for oil palm plasma and assesses farmers’ concerns regarding replanting decisions. The research was conducted in three districts of South Sumatra (OKI, Muara Enim, and Musi Banyuasin) with plasma farmers as respondents. Three financing patterns were  analyzed: self-financing through savings, insurance-based financing, and bank loans. The research used a survey method and sampling was determined with a balanced random sampling technique with 90 respondents. The research concluded that the financing pattern of oil palm replanting can be done through savings, insurance, and bank loans. The best financing pattern for replanting is conducted by using their savings because it can produce the highest net B/C value; NPV; and the shortest payback period. Sensitivity analysis showed that Fresh Fruit Bunch (FFB) price reduction is the most sensitive for the financing patterns of their savings and bank loans, however for the financing patterns of insurance, the decrease in FFB production is mentioned as the most sensitive. The government has to maintain stable FFB pricing, and it is advised that they use their funds, which are arranged by KUD, to support the oil palm replanting. Five factors -complexity, compatibility, relative profitability, trialability, and observability - will be used to gauge farmers’ concerns about oil palm replanting.

Abstract

Psychological well-being is understood differently across cultural contexts, yet many culturally grounded frameworks remain conceptually described rather than empirically tested. One such framework is Pancawaluya, a Sundanese indigenous model that defines well-being through five core values: Cageur (physical and mental health), Bageur (kindness and prosocial conduct), Bener (moral integrity), Pinter (knowledge and wisdom), and Singer (creativity and adaptability). Although these values are widely recognized in Sundanese philosophy and practice, their structure as a measurable psychological construct has not been systematically validated. This study examined the factor structure and internal consistency of the Pancawaluya Scale using Confirmatory Factor Analysis (CFA). Data were collected from 305 respondents and analyzed using LISREL. The results supported a five-factor model with satisfactory model fit indices (RMSEA = 0.031; CFI = 0.985; GFI = 0.958). Composite reliability indicated strong internal consistency, while AVE values suggested acceptable convergent validity for an indigenous construct in an early validation stage. The findings indicate that Pancawaluya can be operationalized as a coherent indigenous well-being construct. Its dimensions are theoretically discussed in relation to Islamic counseling principles, suggesting conceptual alignment in moral and spiritual values. This study provides an initial empirical foundation for future culturally grounded counseling research.

Abstract

Tidal lowland is one of the potential lands for agriculture that is found very widely in coastal areas of South Sumatra. There are about 400,000 hectares (ha) was reclaimed for agriculture purpose. However, in many parts, the rice production is still low (<3 ton/ha), mainly in the high part of hydrotopography class (Type C) that the tidewater could not possibly irrigate the land.  This study aimed to evaluate the level of actual and potential suitability of tidal swamps for rice plants. This research has been carried out in Bandar Jaya Village, Air Sugihan Subdistrict, Ogan Komering Ilir Regency. This research used a survey level method with very detailed (intensive) with a scale of 1:6,000 covering a research area of 16 ha. The results showed that actual suitability for rice plants in the study site is N-n with an area of 5 ha and N-f, n with an area of 11 ha with limiting factors of soil pH and P nutrient. The potential land suitability class for rice plants in the study location is S3-n with an area of 5 ha and S3-f, n with an area of 11 ha. Land quality improvement was done by using the lime application and control water table at a depth of at least 10 cm from the soil surface during rice growth.  Rainwater should be retained in the tertiary block as much as possible to fulfill crop water requirements. Setting the planting time (November-January) and balanced fertilization will be able to increase the land suitability class to S1 (highly suitable).
