AbstractThe sources of pozzolans could be natural, industrial and agricultural wastes that are recycled into concrete and mortar applications. There have also been many studies and recommendations guiding the use of blending these pozzolans from multiple sources with cement with the aim of producing more durable, greener and sustainable mortar/concrete. These investigations are mostly based on testing these pozzolans with a certain type of cement and making recommendations on the optimum percentage replacements. This type of study underscores that a pozzolan can behave differently with other types of Portland cements with varying distinct chemical compositions that associate the cement with its type. This could result to a particular pozzolan having different optimum percentage cement replacements with different types of cement and hence results in less durable concrete of which this study intends to address. The pozzolan used in this study is Pulverized Calcined Clay (PCC) and the types of cement is based on the British and American standards classification. The cement variants used in this study is broadly rapid hardening and low heat cement form the two (2) major cement brands in Nigeria. The X-Ray Fluorescence (XRF) analysis was performed on the cements and the PCC to determine their oxide compositions and classify the pozzolan, the Strength activity index (SAI) of the pozzolan was also determined. The optimum percentage replacements (replacement level with maximum strength) of the cements with the pozzolan was also determined. The results indicate that the optimum replacements for the low-heat cement was at 20% replacement with PCC and substantially higher for the rapid-hardening cement. This could be adduced to the difference in the chemical compositions as shown in the XRF analysis. It was concluded that the optimum replacement of different cement types with a pozzolan could vary, resulting to less durable concrete when a single optimum replacement is recommended across all cement types. It is therefore recommended that the optimum replacements of cements with pozzolans should be specific to a cement type and recommended that optimum replacement for other cement types with same pozzolan be determined and not generalized across all cements.

Published: March 2021

AbstractThe contribution of women to labour in African agriculture is quoted regularly in the range of 60–80%. Using available statistical data, to compare the level of employment and productivity of both male and female on an individual basis, and consequently proffer ways of improve that with a lower turn-out is the one major aim of the study. The contribution of females in the agricultural sector is substantially lower in Nigeria (37%), and some other developing countries. In order to get appropriate estimation of the model, the Augmented Dicky-Fuller and the Phillips-Perron test are used to check the variables level of stationarity. This also helps to explain the existing relationship between and among the following variable: employment in agriculture, male, employment in agriculture, female, trade and inflation. The result informs the need to enhance the employment of female in the Nigerian economy for higher agricultural productivity. Therefore the study suggests that policies geared towards female empowerment in agriculture and services alongside other concerned sectors should be promoted.
Climate change and coastal vulnerability assessment methods: A review
Authors: Oloyede Mary O. , Benson Nsikak U. , Williams Akan B. 
Published: March 2021

Abstract
Coastal and marine ecosystems have been threatened at local and global scales by multiple stressors – sea-level rise, rising temperatures, climate extreme events, biodiversity loss and habitat destruction. These stressors operating independently or synergistically could alter the ecosystem services while posing a significant threat to the environment, human lives and properties, as well as, result in biophysical and socio-economic losses. In this paper, we present an overview of the methods used in assessing coastal vulnerability of marine areas at local-global scales under chronic environmental stressors. Integrated and strategic methodologies that could identify, highlight and prioritise the vulnerable marine areas have been presented. The framework to assist coastal planners and managers in the conservation and management of vulnerable coastal regions and settlements from permanent inundation and loss have been suggested.

Abstract
The problems of post-harvest losses in the developing world have been of severe concerns especially when food security for the citizenry cannot be guaranteed. Thus, new means of the conversion of some of the periodic produce to novel stable products is an exceptional development. In this study, we carried out the production of wine from citrus fruits (Citrus sinensis) and Pineapple fruits (Ananas Comosus) using wild strains of yeast Saccharomyces cerevisiae. The Saccharoymces cerevisiae was isolated from fresh palm wine and identified using microscopic examination, morphological and biochemical characteristics. Pure yeast isolates were inoculated into sterile volumes of 200 ml and 500 ml of the orange and pineapple juice respectively and incubated for eight days. At regular intervals, we assessed some of the intrinsic properties of wine, such as pH, sulphur dioxide, titratable acidity (TA). From the results obtained, all the parameters measured were within the permissible limits for fruit wine. The mean pH values of orange and pineapple juice in 200ml and 500ml were between 4.45± 0.16 and 4.86±0.50; while the mean Sulphur dioxide SO (ppm) were 18.36±0.20 - 39.49±3.68 respectively. The titratable acidity (TA) obtained was between 0.63±0.11 - 1.03±0.59, respectively. This study had shown that our strain of wild type of yeast could be used for producing homebrew fruit wine and may not present any hazard to the consumers.

Abstract
The existence of forest management institutions based on the site level is the philosophy of the birth of an FMU. The purpose of this study is directed to provide an overview related to the performance of FMU development carried out by the Government (central and regional) in Indonesia. This research was conducted during the period of February 2015 to February 2019 in eight FMU areas in seven provinces in Indonesia. Technical data and information through stakeholder interviews result from verification workshops and secondary supporting data collection. The data and information collected are then processed into a working paper on the FMU Development Performance Assessment tool using FWI 1.0 and FWI 2.0 Criteria and Indicators, compiled by Forest Watch Indonesia (FWI). The results are presented in the form of an index by calculating the total value of all data units then divided by the number of data units. The FMU development performance evaluation index can be categorized into three classes, namely high, medium, and low. The results of studies in eight FMU areas illustrate that FMU development at the site level still faces various challenges and problems. The main problems faced are focused on three main aspects namely; Regional Stability which includes clarity of boundaries and tenure conflicts; Institutional Aspects concerning political support and institutional capacity in supporting the operation of FMUs; and the planning aspect which concerns the bureaucratic chain and the stability of the FMU development platform at the site level. Comprehensive efforts from stakeholders are needed to encourage the optimization of FMU functions and roles at the site level.

Authors: Saleh Syafiuddin 
Published: March 2021

AbstractThis study aimed to identify aspects related to the condition and institutional capacity of BUMDes (Village Owned Enterprises) in order to increase added value, marketing and seaweed farming income. This study was conducted in Takalar and Pangkep Regency as seaweed production centers and ponds in South Sulawesi. The research method used in this research was a case study with descriptive data analysis. The results shown that in the two regions there were about 62 BUMDes in Takalar Regency which spreaded in eight districts, and 55 BUMDes in Pangkep Regency spreaded in 12 districts. BUMDes are known as actively rural business units (units) but it is still not well institutionalized. Mostly BUMDes business still revolves around saving and loan businesses in a small scale. Observations in two BUMdes in seaweed production centers, namely in Laikang, Takalar Regency and in Pitusunggu, Pangkep Regency, BUMDes management has not been much in touch with seaweed agribusiness activities. The seaweed-related business unit in the BUMDes is mainly in Pangkep, in the form of processed food products (pastries) whose marketing is still limited so that added value and income are also still low. Other businesses such as trading seaweed products on a larger scale, cannot yet be developed because (1) generally seaweed farmers/cultivators use village middlemen (capital owners) so that their products must be sold back to the capital owners so that the BUMDes can make farmers as business partners (2) adequacy of BUMDes venture capital to develop businesses is still limited (3) skills of BUMDes members in managing businesses is lack (4) marketing reach, has not developed yet, (5) efforts to build partnerships with parties others are also lacking. In the next stage, the appropriate model in the development of the BUMdes is needed.

Correlation between carbohydrate content, protein, and fat with compatibility of durian seed grafting (durio zibethinus. Murr)
Authors: Suharjo  , Nadja R A 
Published: March 2021

AbstractDurian nurseries can be done using generative and vegetative material sources. Both sources of propagation have their respective weaknesses and strengths. To get quality seeds requires a combination of two sources of propagation material that has each of the advantages that can complement each other. The process of merging can be through grafting. The grafting method in durian nurseries can use side grafting and shoot grafting methods. The purpose of this study was to determine differences in levels of protein, carbohydrates, fats, and phytohormones from various sources and storage time of the stem. This study was compiled based on factorial designs in the Randomized Group Design (RCBD). The first factor is the source of the stem (S), which consists of 3 sources, namely the primary branch (S1), secondary branch (S2), tertiary branch (S3). The second factor is the length of storage of the stem (T) which consists of 4 levels of storage time of the scion namely: 0 days (T0), 2 days (T1), 4 days (T2) and 6 days (T3). It was concluded that the carbohydrate content of the sciots gave the highest positive contribution to the increase in the number of shoots followed by the number of leaves, percentage of living grafts, leaf area, leaf area ratio, root canopy ratio, shoot length, and stem diameter. The protein content cannot contribute to the growth of grafted seeds even has a tendency to inhibit growth. The fat content in the scion does not contribute to the growth of plant variables.

Abstract
The serious harvesting failure that occurred in the agricultural year 1979/1980 affected as many as 11.250 hectares. Since 1980/1981, this phenomenon inspired a technological shift in rice production to Directly-seeded flooded rice on rainfed land. Lombok, West Nusa Tenggara province achieved self-sufficiency of rice in 1984, a year before national self-sufficiency in 1985. This research aims to analyze the impact of directly-seeded flooded rice as a climate change adaptation strategy on output supply and input demand. Time series data from 2000 to 2015 was analyzed by employing Translog Profit Function and Seemingly Unrelated Regression. The results showed that Directly-seeded flooded rice as a climate change adaptation strategy has a positive impact on output supply and input demand. It indicated (1) elastic output supply subject to self-price change of rice and labor, yet inelastic to the price of seed, Urea fertilizer, TSP, and NPK fertilizer. (2) All demand inputs were inelastic subject to self-price except casual labor and herbicide, and elastic subject to output price. Herbicide and fertilizers are complementary inputs to the directly-seeded flooded rice, while herbicide and casual labor are substitution inputs. The output and inputs price changes faced by farmers have both positive as well as negative impacts on output supply and input demand. It means that inputs such as seed, fertilizers, pesticides, and energy such as petrol for hand tractors are the main physical inputs to Directly-seeded flooded rice. Those inputs were very strategic economic goods, meanings that when the price changes occurred, it disturbed supply directly and performance of rice farming, either the production side, profits, or price risk. It also has food security impacts in Lombok.
