Soybean is known for its high protein content, which is the reason why it is widely used as one of the main food sources for humans and animals. In order to optimize soybean growth, farmers tend to add excessive dosage of chemical fertilizer to this crop. Furthermore, a continuous chemical fertilizer application without organic fertilizer addition may cause a rapid depletion of nutrients in the soil. This study aimed to evaluate the effectiveness of organic fertilizer treatment to reduce the amount of urea as chemical fertilizer needed in soybean cultivation. A complete randomized design was conducted using 21 treatments of organic and chemical fertilizer in triplicate with a 4x3 m plot size. Analysis of variance was carried out to compare the means of measurement data and Duncan multiple range test (DMRT 5%) was applied. The treatment 2,000 kg ha-1 compost + 50 kg ha-1 urea (O2K2A1) resulted the highest dry yield in soybean and had significant differences with urea-only treatment. A mixture of chemical and organic fertilizers had no significant result over the yield compared to the use of chemical fertilizer only. Compost application of 1,000-2,000 kg ha-1 with urea 50-100 kg ha-1 (O2K2A1 and O 2K1A2) showed an increase in seed yield of 35-38 % with a profit reaching 333-340 USD ha-1 compared to standard treatment using urea 50 kg ha -1 + SP-36 50 kg ha-1 + 50 KCl kg ha-1 (O0K0A1).

Biochar Amendment

The first objective of this study was to assess the effects of coconut shell biochar in propagation substrate on seed germination and seedling growth of Coreopsis grandiflora (Hogg ex Sweet) ‘Early Sunrise’, Leucanthemum ×superbum (Bergman ex J. Ingram) ‘Silver Princess’, and Eschscholzia californica (Cham.). Cornell seed germination mix was amended with the biochar (0%, 5%, 10%, 20%, or 40%, v/v). Seed germination and seedling growth were determined during a 21-day period in two germination rooms. This particular biochar amendment did not affect final germination percentage for any of the species. All three species had seedling shoot and primary root length growth with low to moderate positive correlation (r = 0.33–0.54) with coconut shell biochar amendment volume. Coreopsis seedling dry weight was significantly higher with 40% biochar than the control (P ≤ 0.05). The second objective of the study was to compare digitally collected data with manually collected data. Two-dimensional scans of Coreopsis and Leucanthemum seedlings were collected. Seedling dry weight (mg) and seedling length (mm) predicted seedling two-dimensional area for Coreopsis (R2 = 0.73, P < 0.001) and Leucanthemum (R2 = 0.87, P < 0.001). Digitally traced shoot and root lengths were strongly positively correlated (r = 0.99–0.97) with manual ruler measurements, suggesting that digital imaging could replace manual length measurements. The results of this study suggest inclusion of this particular coconut shell biochar in seed germination, and establishment substrates can have neutral or positive effects on herbaceous perennial germination and establishment.

Electricity Tariff

The aim of this study was to analyze the impact of 900 VA electricity tariff adjustments on household consumption patterns in East Borneo. This policy potentially increased the poverty, considering that in the last few years, East Borneo had experienced a contraction in economic growth. The analysis of this study used the Linear Approximation of Almost Ideal Demand System (LA/ AIDS), and the concept of elasticity to reach the objectives of this study using Susenas in 2016 and 2017. The results of the analysis showed that the policy indirectly had more impact on all residential electricity customers rather than on 900 VA and above customers. The residential electricity customers would generally be more responsive to reduce the non-staple consumption in addition to respond the subsidies revocation, compared to 900 VA and above users. This circumstance was certainly related to the economic condition of 900 VA and above residential electricity customers who were more capable, so the food needs were no longer a household staple. Meanwhile, the middle economic households would continue to maintain the nutritional status of the household by continuing to consume high protein food sources (fish / meat / eggs / milk). Meanwhile, based on the type of region, the revocation of 900 VA subsidies and the increase in household non-subsidized tariffs for rural was more responsive than urban households. This was understandable since the level of electricity dependence

The role of the agricultural sector as a provider of food and non-food sources is directly related to the 2030 SDGs target of eradicating poverty and hunger. In Kubu Raya, one of the developing areas in the agricultural sector is Rasau Jaya District, with main crops being food crops and vegetables for food security. Agricultural land in Rasau Jaya District is dominated by peatlands with 14,371,392 hectares area. This study aims to determine the form of peatland use into potential land, the role of agriculture as a provider of food and non-food sources, and the form of its use. The method used is remote sensing method and survey method. The results showed that land use in the Rasau Jaya District included rice fields, gardens, fields, moor, yards, settlements, forests, shrubs, water bodies, and vacant land. Food crop agricultural products are used to meet food needs as well as non-food needs such as education and health. Most people use the harvest for personal consumption and for sale. There are still not many people in Rasau Jaya District who process agricultural products into a product. Farmers sell their crops in several ways, among others: directly sold to consumers, sold directly to the market by opening their own kiosks, deposited with middlemen and agents, and taken by investors who invest in farmers.

Rapid Multiplication Technique (RMT) is a technique used to produce large scale cuttings of sweet potato in a short period by using mini cuttings and proper fertilizer management. The research was carried out from October 2019 to March 2020 and composed of two experiments The first experiment involved a randomized complete block design, with clones (“Ase Kapas” and “Ase Merah”) as the first factor, and tuber weight (150 ± 25 g, 250 ± 25 g, and 350 ± 25 g) as the second factor. The second experiment was arranged in a split-plot design involving different doses of NPK compound fertilizer (as main plot) and different source of cuttings (as subplots). The different doses included NPK 16:16:16 at 100 kg.ha-1 (0.3 g per polybag), 200 kg.ha-1 (0.6 g per polybag), 300 kg.ha-1 (0.9 g per polybag), and without fertilizer as control. The source of cuttings were from the tip, middle and bottom stem of the plants. Results showed that the “Ase Kapas” showed the highest number and the longest shoots, number of nodes, and length of vines. Additionally, tuber weight of ± 350 g produced the highest number of shoots. When it comes to NPK compound fertilizer treatment, a dose of 0.9 g per polybag increased cutting production in “Ase Kapas”, and also responded better to fertilizer treatment. On the other hand, dose of 0.3 g increased cutting production in “Ase Merah”. “Ase Kapas” produced more cuttings from the middle stem, whereas “Ase Merah” produced more cuttings from the . The application of RMT in “Ase Kapas” produced cuttings with ratio of 1:31, which is higher than those in “Ase Merah” with a ratio of 1:17.

Food Needs

The Orang Rimba are a hunting-gathering group that lives depending on the availability of the forest. Forests not only function as livelihoods but also have cultural significance as a resource for their cultural traditions. However, in the last few decades, forest conversion in Jambi province has increased. The increased function of forests in Jambi from forests as plantation areas, mining areas and industrial plantation forest areas has made the lives of the Orang Rimba as a hunting-gathering group increasingly threatened. Food security is a condition in which all people, at any time, have access both physically, socially, and economically to adequate, safe, and nutritious food which can meet food needs and food preferences for an active and healthy life. Through the micro ethnography approach, the purpose of this paper is to know and understand the phenomenon of food security from the perspective of the Orang Rimba as seen from its availability, adequacy, affordability, and security. Orang Rimba have food security by relying on food sources available in the forest. In a state of urgency they will return to the forest.

Coconut Shell Biochar

In this paper, coconut shell biochar (BC), pickling biochar (HBC), and nano-zero-valent iron-loaded biochar (nZVI-HBC) were prepared; these were used to remove oxytetracycline (OTC), and the removal mechanism and degradation product were analyzed. These biochars were characterized using SEM, XRD, FTIR, and XPS. The effects of biochar addition amount, pH, ion type, and ion concentration on OTC adsorption were studied by a batch adsorption experiment. Under the optimal conditions, the equilibrium adsorption capacity of nZVI-HBC to OTC was 196.70 mg·g−1. The adsorption process can be described by Langmuir isothermal adsorption equations, conforming to the pseudo-second-order dynamics model, indicating that adsorption is dominated by single-molecule chemical adsorption, and a spontaneous process of increasing heat absorption entropy. Mass spectrometry showed that the OTC removal process of nZVI-HBC included not only adsorption but also degradation. These results provide a practical and potentially valuable material for the removal of OTC.
