Abstract

ABSTRACT: Tomandin Fakfak nutmeg (Myristica argentea Warb) is an important source of income for the people in Fakfak. The plantation development of this nutmeg requires knowledge of plant propagation techniques, one of which is through cuttings. This study aims to study the effect of giving commercial auxin (Rootone), and auxin in the form of a mixture of NAA, and IBA on the success of Tomandin Fakfak nutmeg cuttings, both using cutting materials from seedlings and adult plants. The study was designed in a Complete Randomized Design (RAL), with auxin treatments: control (without auxin), Rootone applied in paste form, a quick dip in IBA/NAA solution (1000/500 ppm), and IBA/NAA (2000/1000 ppm). The research was carried out in 2 (two) sets of research, i.e. using cutting material from seedlings and adult plants. The results showed that the propagation of Tomandin Fakfak nutmeg plants through cuttings was prospective to be developed as an alternative plant propagation technique, even though the success was still low. The best treatment of seedling origin shoot cuttings was found in the application IBA/NAA solution (1000/500 ppm), with rooted cuttings of 12.5%. Cuttings of shoots from adult plants are only able to form calluses, with the highest live cuttings (56.25%) in the treatment of IBA/NAA (1000/500 ppm) and IBA/NAA (2000/1000 ppm).

Abstract

ABSTRACT: Soybean husk is waste from the tempe making process which contains organic materials and nutrients so that it can be used as raw material for making organic fertilizer. The use of organic fertilizer on vegetable plants is one effort to meet the need for organic vegetables. This research aims to obtain information on the nutrient and heavy metal content of liquid organic fertilizer for soybean epidermis and the effect of this fertilizer on the growth and yield of pak choy. This research was carried out in December 2022-July 2023, in Citeureup, Bogor and the Laboratory of the Faculty of Agriculture, IPB University. The experimental design used was a Randomized Block Design with three replications. The liquid organic fertilizer treatments used consisted of control, 5%, 10%, 15% and 20%. The parameters observed were plant height, number of leaves, leaf area and plant wet weight. The results showed that liquid organic fertilizer from soybean epidermis contained C-organic (1.63%), C/N ratio (20.13), macro nutrients (N+P₂O₅ +K₂O) 0.42%, total and available Fe (26.61ppm and 25.56 ppm) and Zn (0.42ppm). The heavy metal content (Pb, Cd, Cr, As, Hg) meets the quality standards set by the Minister of Agriculture of the Republic of Indonesia No. 261 of 2019, so that it can be applied to plants. Liquid organic fertilizer with a concentration of 5% was the best supporting growth and production of Pak Choy compared to the control, 10%, 15% and 20%.

Abstract

ABSTRACT: This research aims to analyze forest stand conditions that influence the microclimate in Manokwari urban forests and microclimate conditions that can provide comfort for the surrounding environment. The results of satellite imagery photos show that Manokwari city's land use is forest in the 5 year period, there has been a change in land use area, in 2017 the residential area was 1,512.34 ha to 1,714.58 Ha in 2022, there was an increase of 202.24 Ha. The temperature inside the forest area was recorded at 26.3°C, while outside the forest area it was recorded at 31.1°C. Manokwari has experienced extreme microclimate changes over the last 5 years, the temperature has increased to around 1.5°C, apart from that the humidity has also been recorded to have decreased significantly. Analysis of the comfort index shows that the forest temperature in the Amban region is lower than in other areas studied. Another important thing is that areas in the city that have stands of trees can immediately be designated as urban forests. Based on an analysis of oxygen consumption in various sectors and its population, Manokwari City requires the development of around 918.96 ha of urban forest. To maintain the continuity of the microclimate, it is necessary to immediately issue regulations by the Regional Government regarding the designation of existing areas as urban forests.

Abstract

ABSTRACT : This research aims to identify the diversity of morphological characteristics of several sweet potato accessions cultivated by communities in the two tribes in the Kaimana Regency. The research was carried out in the Lower Arguni District in 5 villages (Coa, Afu Afu, Wetuf/Sawi, Kufuryai, Wermenu) inhabited by the Irarutu and Dani tribes (a local tribe from Wamena). The research used descriptive methods with survey, observation, and interview techniques. The research location was determined deliberately (purposive sampling) based on the local tribe population. The sweet potato in each village was also determined deliberately (purposive sampling) based on the number of accessions and different morphological characteristics. Observation of morphological characteristics included the morphology of stems or tendrils, leaves, and tubers. Data analysis was carried out using cluster analysis with pro- gram NTSYS-pc version 2.0. The morphological character similarity coefficient used is the simple matching coefficient. The research results showed that there was morphological diversity in 26 sweet potato accessions cultivated in five villages by the Irarutu and Dani tribes from Wamena. Diversity in morphological characteristics occurs in the characteristics of tendrils/stems, leaves, and tubers. Based on the results of the grouping analysis, the coefficient of similarity in morphological characteristics of the 26 sweet potato accessions was between 0.41 and 1, which means that the similarity in morphological characteristics was between 41% and 100%. The 26 sweet potato accessions were not grouped based on the village where they were grown but were grouped randomly. At the lowest similarity in morphological characteristics, namely 41%, 26 accessions were grouped into two groups, namely: group I consisted of 17 accessions, while group II consisted of 9 accessions. At the highest similarity, namely 100%, there are several accessions that group together, namely AfuAfu-6 and Wetuf-2; Coa-4, Afu Afu-7, Kufuryai-5; and Afu Afu-10, Wetuf-4, Kufuryai-1.

Abstract

ABSTRAK: The Indigenous population in Papua has employed a zoning system for land usage as a method of spatial planning. The zoning system categorises spaces into hunting and returning zones, permanent hunting zones, gardening zones, fishing zones, crocodile egg-laying zones, sacred zones, sago hamlet zones, customary protected zones, and residential zones. The geographical organisation of these indigenous communities was derived from the participatory mapping technique of traditional territories. The outcomes of the participatory mapping were categorised and analysed geospatially, using vector data analysis from thematic maps of natural resource utilisation through the amalgamation of features of the same type with varying lines and polygons. The selection of vector data employs the select by attribute approach, and the outcomes are included into the Papua Province Spatial Plan (RTRW) focussing on land cultural heritage regions. The area of customary lands identified by participatory mapping is 2,201,311 hectares. In the Papua Province RTRW 2023-2043, 8,778.50 hectares are classified as a cultural heritage land area

Abstract

ABSTRACT: This study investigates the development of environmentally friendly briquettes as a sustainable alternative fuel. Production involved utilizing sub-bituminous coal waste and carbon derived from the carbonization of seaweed. The primary objective of this research was to optimize the briquette composition to achieve optimal combustion performance, with a focus on reducing the emissions of harmful combustion byproducts, such as SOx (sulfur oxides), NOx (nitrogen oxides), COx (carbon oxides), and particulate matter. The results indicate that briquettes with a 1:1 ratio of coal to seaweed carbon, carbonized at 300°C (sample 3A1), demonstrate potential as an alternative fuel. The 3A1 briquettes exhibited a calorific value of 4422 cal/g, with SOx and NOx emissions that were 11.11% and 25.00% lower compared to pure coal briquettes. This reduction is attributed to the lower sulfur and nitrogen content in the seaweed, as well as the improved carbon structure stability resulting from the carbonization process at 300°C. The utilization of coal waste and seaweed in the form of briquettes represents a viable approach to mitigating environmental impacts and contributes to the development of clean and sustainable energy.

Abstract

ABSTRACT: Civil servant extension workers are given full duties, responsibilities, authorities and rights by authorized officials in organizational units within the scope of agriculture, animal husbandry, fisheries and forestry to carry out extension activities. Field agricultural extension workers have the main tasks and functions that must be carried out to achieve good performance. This study aims to evaluate the performance of field agricultural extension workers and what factors affect the performance of field agricultural extension workers in Sorong Regency. This research was conducted through interviews using questionnaires where sampling was carried out by census of 73 respondents of civil servant field agricultural extension workers consisting of 56 agricultural extension respondents and 17 livestock extension workers. Data analysis applied by tabulation with competency test techniques and then using PLS analysis (Partial Least Square). The results showed that the performance of field agricultural extension workers in Sorong Regency as a whole was in the medium category. PLS test results shows that there is a significant influence relationship between the performance of agricultural extension workers with internal factors consisting of age and education while external factors consist of information technology accessibility, appreciation and coaching and supervision. It can be concluded that the performance of agricultural extension workers in Sorong Regency overall still shows performance achievements that have not been fully reached.
