International Journal of Agriculture System VOLUME 10 ISSUE 1, JUNE 2022
Publisher : Hasanuddin University

The tendency of chemical fertilizers used (inorganic) in food crop cultivation farming by the farmers is caused by their practicality. However, the continuous use of chemical fertilizers can damage the crops and their environment, including sweet corn. Sweet corn (Zea mays L. Saccharate) contains high sugar content because it naturally mutates to a recessive gene that controls sugar conversion to starch in corn endosperm. The purpose of this research were to know the effect of several organic fertilizers on productivity increase as well as Brix content of sweet corn. This research was conducted from June to August 2021 in Waempubbu Village, Amali District, Bone Regency and Laboratory of Food Process, Agriculture Faculty, Hasanuddin University, South Sulawesi. This research used the design of a split plot by using completely randomized design (CRD). The main plot was sweet corn varieties: Talenta (v1) and Bonanza (v2). Meanwhile, the subplot was organic fertilizers which are control (p0), compost (p1), soil ameliorant (p2), compost + soil ameliorant (p3), liquid organic fertilizer/LOF (p4), compost + LOF (p5), soil ameliorant + LOF (p6) and compost + soil ameliorant + LOF (p7). According to the results, the Bonanza variety showed high average productivity, 22.50 tons per hectare. The treatment of organic fertilizer that reveals the high average productivity is combines compost + soil ameliorant + LOF (p7). The interaction of treatment that reveals the highest productivity is an interaction between Bonanza variety with the treatment of soil ameliorant + LOF (p6), which is 27.07 tons per hectare with Relative Agronomic Effectiveness (RAE) value is 1366.67%. The treatment of compost fertilizer + soil ameliorant + LOF (p7) exhibits the content of Brix (10.50%) and becomes the highest productivity.

Farmers Participation in Irrigation Management and Its Influence on Production and Productivity of Rice Farming A. Nixia Tenriawaru; Muh. Hatta Jamil
International Journal of Agriculture System VOLUME 2 ISSUE 2, DECEMBER 2014
Publisher : Hasanuddin University

Utilization and management of irrigation, especially in the tertiary is the duty and responsibility of farmers involved and cooperate in farmer water user associations (P3A). This is confirmed in Article 1 No. PPRI. 20 of 2006 that, the utilization and management of tertiary irrigation network would be the part of farmers and requires an organization known as farmers’ water user associations (P3A). Through such participation, farmer members of P3A may gain knowledge derived from the results of their interactions with fellow members of P3A or other parties related to irrigation activities and ultimately may affect the achievement of the production and productivity of rice farming optimal. This study intends to examine the extent to which members of P3A farmer participation in irrigation management affect the production and productivity of rice farming in each tertiary, Bila Kalola irrigation. Survey method in this study is intended to obtain the required data through questionnaires to 324 farmer members of P3A in 41 affiliated P3A, which influence the participation of farmers on production and productivity of rice farming are analyzed through simple regression analysis and analysis of Cobb-Douglas production function. The results showed that: the more active participation of farmers in irrigation management activities, the increasing of production and productivity achieved, although this hypothesis has not been fully proven in each tertiary on Bila Kalola irrigation.

The multifunction of pigs for the Papuan are divergences and interelated. This study was aimed to seek the objectives of keeping pigs by Arfak tribe and to find the trend relationships of economical and socio-cultural components determining the development of pig farming systems in Manokwari. A one-month field research was done at Manokwari Barat district. Quiztionaire was the tool used to record and collect the data. Snowball method was applied to chose the pig farmer participants and 60 respondents were participated. Several variables were quantified to measure the percentages of socio-cultural and economicalobjectives. The finding shown that income generation, savings barter were the subsequent components shaping the economic objectives and while organic fertilizer and biofertilizer resulted from manure were not applied yet. Although dung was frequently produced and spreaded at the pig house and around backyard. Socio-culture was done in the means of merrital prices, peaceness, gift and parties, respectively. The other findings were that the alternation of pig development indicated by herd size had positive relationship with the two motives. Similar relationship was shown by number of aided farmers. Hence, the changes of pig farming systems, e.g. extensive to semi-intensive and/or intensive to semi-intensive had shown weak relationship.

Public Perception and Participation in Environmental Preservation of Watershed Andi Bustan
International Journal of Agriculture System VOLUME 4 ISSUE 2, DECEMBER 2016
Publisher : Hasanuddin University

Environmental aspects have been some of the most argued about topics in society, including the role of the government as a stakeholder. Deforestation and illegal mining have been destroying the many ecosystems and rainforest habitats, including along the Katingan Watershed. The research objective is to describe public perception and participation in environmental preservation. The research used descriptive qualitative method and applying Spradley Domain Analysis. Primary and secondary data were obtained directly from field informants using interviews, observations and documentation. The research results show that the people’s perception and participation in environmental preservation was categorized into two groups. The first group one stated that they did contributed out of personal and financial interests, whilst the second groups were simply following the instructions of the government and local leaders. In general, locals have different perception on how they utilize the natural resources. The management of natural resources was perceived as being done for economic reasons, with the assumption that it were used sustainably. People’s involvement in preserving nature were affected their own needs either individually or collectively. Participation of the people in the conservation around the watersheds area was done for reasons of individual desire, solidarity, and to follow instructions from the government and Katingan Hilir leader. Environmental effort is carried out in activities aiming to protect and prevent damage to the area of the Katingan River. This lead to argue that diverse people’s perception to preserving environment generates the difference participation in their awareness.

Can Agroforestry Farmers Attain Sustainability? Case of Farmers in Selected Upland Farming Communities in the Philippines Leila Dimayuga Landicho; Josefina T. Dizon; Agnes C. Rola; Maria Ana T. Quinbo; Rowena DT. Baconguis

This article is based on the study which investigated the socioeconomic and biophysical conditions of the upland farming communities in the Philippines; identified the development pathways that were undertaken by the upland farmers; and determined level of sustainability of the upland farming communities on the basis of their development pathways. This article argues that agroforestry farmers in upland farming communities in the Philippines can attain sustainability. This argument is based on the study conducted in the three pilot upland communities of the Conservation Farming Villages program in Albay, Ifugao and Negros Oriental, Philippines. From seven focus group discussions (FGDs) with at least 12 participants per FGD for a total of 147 farmers, and farm household survey of 230 upland farmers, research results indicate that agroforestry farmers in the three study sites were smallholders and were cultivating in areas with marginal conditions. There were five development pathways identified. These are monocropping in contour, multiple cropping in contour, agroforestry, agroforestry with non-farm activities, and multiple cropping/monocropping without contour. With the community capitals framework as the theoretical foundation, analysis indicated that the five development pathways contributed to a high level of social, human and political capitals having mean scores of 0.73, 0.55 and 0.54, respectively; a moderate level of physical, financial and natural capital, with mean scores of 0.23, 0.20 and 0.23, respectively; and a very low level of cultural capital with mean score of -0.08. At the community level, on the other hand, research results revealed that the CFV sites in Ligao, Albay and La Libertad, Negros Oriental have almost similar contributions to the sustainability of the upland farming communities, while Alfonso Lista, Ifugao had the lowest. Thus, institutional arrangements with the farmers’ association and the local government units also played a key role in the sustainability of the upland farming communities. These results imply the need for a holistic and collaborative engagement towards attaining sustainable upland farming communities.

The purpose of this research are: (1) to analyze the dimensions that construct the entrepreneurship orientation of broiler husbandry entrepreneur in partnership and independent scheme, (2) to analyze the influence of entrepreneurship orientation on business performance of broiler husbandry in the partnership and the independent scheme. This research was conducted in March-May 2017, employed 30 respondent farmers on each partnership and independent scheme. Structural-Partial Least Square Equation Modeling (SEM-PLS) was employed for quantitative analysis. The results of this study indicated that the dimension of entrepreneurship that can be observed from the business actors of broiler husbandry in the independent scheme at the Bogor Regency was innovative, proactive, risk- taking, autonomy and competitive aggressiveness. While in the partnership scheme there was no observable orientation dimension. The partnership scheme showed a negative and insignificant influence of entrepreneurship orientation to business performance, whereas the independent scheme showed a positive and significant influence of the entrepreneurship orientation to the business performance.

Nitrate and phosphate nutrient and the other oceanographical parameter are part of an indicator to evaluate the quality of the water environment. Our research aims to determine the nitrate and phosphate levels in the water and sediment along the Pangkep coastal area. The research was conducted in February 2018 in coastal Pangkep using five sampling stations. Physico-chemical parameters of the water, such as temperature, pH, salinity, and dissolved oxygen were measured directly, whereas nitrate and phosphate parameters were analyzed using a spectrophotometer. In addition, nitrate and phosphate parameters from the sediment were measured using an atomic absorption spectrophotometer. The sediment nitrate values ranged from 0.026-0.442 mg/L, and the water nitrate values ranged from 0.018-0.063 mg/L. Moreover, the phosphate values from sediment ranged from 0.019-0.306 mg/L, and the phosphate values from the water ranged from 0.13-0.056 mg/L. The results show decreasing values of nitrate and phosphate concentration in the water and sediment starting from the estuary to the sea. The highest values were indicated in the estuary, which represents a eutrophic condition in the environment. Nutrient enrichment in coral reefs occurs and mixes with oceanographic conditions resulting in oxygen depletion and changes in benthic community structure.

The Strategy of Phytoplankton on Critical Conditions in Coastal Waters Rahmadi Tambaru; Muh. Farid Samawi; Khairul Amri
International Journal of Agriculture System VOLUME 8 ISSUE 1, JUNE 2020
Publisher : Hasanuddin University

The productivity of phytoplankton found best in coastal waters is on a critical aquatic environmental condition for the life of phytoplankton (incubation time : 10.00-14.00). At that incubation time, the sun reached the apex of illumination (12.00). Theoretically, the best productivity is unlikely to happen because the activity of phytoplankton is not perfect. To answer that doubt, the research deals with the strategy of life phytoplankton on critical conditions in coastal waters. To achieve the desired results, multivariate analysis is used Correspondent analysis (CA) and Principal Components Analysis (PCA). The results showed that based on the analysis of Factorial Koresponde (CA), there were two grouping of phytoplankton abundance. Group I showed that the grouping of phytoplankton abundance of occurred at A depth of 10 m at the sampling time A (10.00 : normal conditions). Group II occurs at a depth of 5 and 15 m at sampling time B (14.00: critical condition). Furthermore, the shift in grouping phytoplankton occurs at the sampling time A at a depth of 10 m into the sampling time B in 5 m depth, not at at a depth of 0 m. This is due to the very strong sunlight intensity that can lead to death in the genera of phytoplankton that exist. It turns out that the strategy and the dynamics of phytoplankton abundance at critical time is not doing the grouping at the surface depth (0 m), but at a deeper depth (5 m) in order to keep the activity well done.

A series of researches was carried out to obtain mutant of maize induced by gamma rays irradiation. This initial report was from a study confirming the best dosage of irradiation at 50% lethal dosage (LD50) conducted at the Laboratory of Seed Science and Technology, Faculty of Agriculture, Hasanuddin University, Makassar from March to June 2012. The research was set up using split plot design of the Randomized Complete Block design. Data were analyzed using analysis of variance. Results showed that: Gamma ray dosage affected maize seed viability. The higher gamma ray dosage used resulted inmore inhibiton of maize seed germination. The best LD50 irradiation to induce putative mutation (M1) in maize seeds tested ranged from 100-200 Gy. The genotype Lamuru maize irradiated at 100 Gy were superior and were more viable with a percentage germination of 87.22% and vigor index of 4.48.

Ornamental Plant’s Potentials of Indonesian Native Rubiaceae Collected in Cibodas Botanical Garden Dwinda Mariska Putri; Decky Indrawan Junaedi; R. Hendrian
International Journal of Agriculture System VOLUME 9 ISSUE 1, JUNE 2021
Publisher : Hasanuddin University

Cibodas Botanical Garden (CBG) is an ex-situ plant conservation institution, maintaining living collection from various taxa including Rubiaceae. Most of Rubiaceae ornamental plants are introduced species with regard to their attractive characters. However, introduced species of ornamental plants is one of significant global plant invasion pathways. The aims of this research was to conduct inventory study of CBG’s Rubiaceae collection, to determine native and introduced species, and to bring out CBG’s native Rubiaceae potential as ornamental plants. The research was divided into two methods, field study and literature study. Field study was conducted by making inventory of Rubiaceae living collections and plant morphology observations. Literature study was conducted by obtaining data of plant distributions, utilization as ornamental plants, and also comparing domesticated species with CBG’s living collections. Results showed that CBG has collected 20 genera, 50 species and 116 specimens of Rubiaceae as living collections. There are 22 native species, 15 introduced species and 13 species that can not be determined. There are 5 species commonly utilized and cultivated as ornamental plants, 8 species are not known for their aesthetic characters but has potential as ornamental plants. These species are Gardenia pterocalyx Valeton, Hypobathrum frutescens Blume, H. racemosum (Roxb.) Kurz, Mycetia cauliflora Reinw., Pavetta montana Reinw. Ex Blume, Psychotria angulata Korth, P. montana Blume, and Wendlandia densiflora (Blume) DC. This study demonstrated that there is a promising potential from these lesser-known native Rubiaceae species for ornamental use. CBG should conduct more research about native species’s potential as ornamental plants.
