Authors: Setiyoko Agus , Perwita Sari Yuli 
Published: May 2024

Abstract
Cowpea (Vigna unguiculata L.) has limited characteristics since it has a high content of antinutritional properties. The pretreatment process by a combination of germination and roasting of cowpeas, called pretreated cowpea was done to prepare the flour made from cowpeas. The purpose of the study was to investigate how the pretreatment of cowpea flour affected the antioxidant content and other characteristics of white bread. This study used 0-10.4% (w/w) of the flour as a wheat flour substitute for making white bread. The dough was baked at 175°C for 40 minutes. The results showed that substituting pre-treated cowpea flour affected the bread colour, volume expansion, total phenolic content as well as antioxidant capacity. Pre-treated cowpea flour enhanced the total phenolic compound, antioxidant activity, moisture content, and darker colour, whereas the expansion rate was reduced. The best formula was found by using 5.2% of pretreated cowpea flour. It has good characteristics at colour properties, volume expansion by 12.14%; moisture content was 27.62%, total phenol was 86.24 mg GAE/100 g, antioxidant activity was 29.67 %RSA, and sensory score was 3.75 (preferred). Therefore, the pre-treated cowpea flour can be utilized as a natural antioxidant source in white bread recipes.

Abstract
The increase in egg-laying chicken population must be balanced with the increase in productivity. The productivity (quantity of eggs produced), which affects profitability, can be obtained with sufficient and high-quality drinking water (determined by its pH levels). One of the poultry farms in Jember, Rizqie Farm Partners, experienced a problem with the management of water and feed provision for the egg-laying chicken especially in rainy seasons. The farm is located in an open space and is approximately ±25 meters from the owner’s house, making monitoring and controlling of the drinking water irregular. It is pivotal to be disciplined in controlling the drinking water so that the chickens do not become stressed. The objective of the study is to develop a smart automated system for monitoring drinking water to increase the quality and quantity of egg production. Sensor data connected to the Arduino Uno was converted to an Android smartphone as a controlling and monitoring medium. The stages carried out included problem identification, literature study, data collection, system creation using the design sprint software development method, testing, and data analysis. The pH sensor test results on bottled mineral water, tap water, orange juice, water mixed with soil, and water mixed with vitamins for chickens were 3-8.27 for each type of water. The pH indicator paper as a comparison of the results with the sensor has an accuracy level of 85.06% and an error value of 14.94%.

Abstract
The Lamongan Volcano Complex has a very different character from the Bromo and Argopuro Volcano groups. Lamongan Volcano has 37 volcanic cones and 27 maars (ranu). This volcano is quarter-old and occupies part of East Java Province. Maar Bethok is composed of lava and intercalation between pyroclastic deposits from phreatomagmatic and magmatic falls that still need to be firmly consolidated. These pyroclastic deposits characterize a strombolian eruption with more lava dome or crater wall material ejected. The rocks that make up the Bethok maar include olivine-pyroxene basalt lava and pyroclastic fall deposits with fragments of olivine basalt and basalt composition. The evolution of the Bethok maar eruption started from magma with an alkaline composition and ended with a more acidic composition. The magmatism of Bethok maar has an island arc calc-alkaline affinity.

Abstract
Groundwater is vital element for living. One of methods to identify groundwater potential is Electricity Resistivity Tomography (ERT). This study aims to identify the groundwater potential occurrence in Sleman, Yogyakarta through non-destructive geoelectrical surveys. Based on the ERT models and geological information, supported by hydrogeological data in the research area, drilling a well at the planned location was deemed necessary to reach a depth of at least 100 to 250 meters in order to tap into the maximum groundwater potential. Groundwater is predicted to flow and accumulate in the pores and fractures of rocks. Well drilling in the northern part of section line 1 was more favourable and recommended due to the lower elevation compared to the area of section line 2, where the drill location was originally planned at a higher elevation uphill. Layers of hard rock, presumably lava and breccia, have already been found at a depth of 5 to 15 meters based on historical open well excavations around the area. Identifying the characteristics of subsurface volcanic rocks during drilling is suggested to evaluate drilling and well planning. Well logging should be conducted to collect lithostratigraphy and rock mass information. Further tests of hydraulic conductivity for each potential layer.

Abstract
Indonesia is the country with the largest rice producer. One of the provinces that is a national rice granary is West Java Province, specifically Cianjur Regency which is the third largest contributor of rice products in West Java. In determining the area of rice fields, knowledge of spatial information is very necessary, processing can be done using remote sensing. Remote sensing is able to detect land use and land cover changes. The data needed is Landsat 8 imagery in 2013 and Landsat 8 imagery in 2020. This spatial analysis of land change passed an accuracy test using the Kappa Coefficient method. The results of the analysis carried out over a period of 7 years showed that there was an increase in the area of rice fields amounting to 16671.2 Ha. From this relationship, the 2013 image calculation gets a production value of 801,622 tons or 8.02 tons per hectare, and the 2020 image gets a production value of 1,108,388 tons or 7.89 tons per hectare.

Abstract
In offshore drilling activities, the employment of seawater mud is indispensable, and its adoption is steadily increasing. Traditionally, attapulgite has held a dominant position as the key element in seawater mud composition. However, a shift is underway towards substituting attapulgite with bentonite owing to the manifold advantages that the latter presents. Bentonite boasts favourable viscosity characteristics and efficient control over water loss, outperforming attapulgite particularly in terms of its capacity for clay absorption. Nevertheless, to harness its thickening capabilities for use with seawater, bentonite necessitates a preliminary hydration process. The pre-hydration procedure involves the amalgamation of seawater and bentonite at a low mixing speed for a duration of 10 minutes, succeeded by a resting interval spanning 16 hours. The integration of this pre-hydrated bentonite system necessitated an extensive research undertaking, encompassing a comprehensive review of pertinent literature, the collection of seawater samples, laboratory experiments conducted at three distinct temperatures comparing both fresh water and seawater formulations, the incorporation of diverse additives to augment the assessment of the mud’s physical attributes, meticulous measurement of the drilling mud’s physical properties, implementing treatments to enhance measurement values under heightened temperatures, meticulous analysis of acquired data, and the comprehensive documentation of research findings in scholarly publications. The crux of this research endeavour lies in attaining the objective of incorporating pre-hydrated bentonite as a pivotal constituent within seawaterbased drilling mud. The realization of this goal hinges on the congruence of the measured physical properties of the drilling mud with predefined specifications. Through a rigorous exploration of these methodologies and a systematic approach to research, the study endeavours to foster advancements in seawater-based drilling mud formulations and their operational effectiveness within offshore drilling contexts.
