Instant chocolate drink is a type of processed chocolate product that has many devotees, the use of sucrose as a sweetener for flavour in the process of making instant chocolate drinks can have side effects on health, namely it can cause heart attacks, allergies, diarrhoea, increase the risk of bladder cancer, hypertension and migraines. Stevia leaves contain glycosides which have a sweetness level of 250 higher than sucrose. The purpose of this study was to determine the effect of stevia sugar as a natural sweetener in the manufacture of instant chocolate drinks. The method used is a laboratory study using a single factor at 3 levels of treatment, namely the concentration of instant chocolate and stevia sugar used as much as 11g and 7g; 9g and 9g; as well as 7g and 11g. Data analysis used two methods, namely the Chi-square method for organoleptic data and the One Way ANOVA method with a 95% confidence level followed by Duncan's New Multiple Test (DMRT). The results of this study are samples with concentrations of cocoa powder and stevia sugar as much as 11g and 7g are the best treatment by having a colour parameter value of 4.13 (like), taste parameter of 3.80 (somewhat like), aroma parameter of 4.13 (like), the viscosity parameter is 4.33 (like), the water content parameter is 4.14%, the solubility parameter is 90.15%, the pH parameter is 6.4 and the total dissolved solids parameter is 9.03.

The Batulayar sub-watershed, also known as the Bongomeme sub-watershed, is one of the most important sub-watersheds in the Limboto watershed. Because there are oil palm and other plants in the Batulayar Sub-upstream watershed's area that cause drought and natural harm. The goal of this study was to assess the severity of the drought and develop a hydrological model for calculating the drought index in the Batulayar sub-upstream watershed's area. The mix approach was utilized, which combines Soil and Water Assessment Tool (SWAT) modeling with field survey methodologies. The study's findings suggest that land conversion in the Batulayar Sub-upstream watershed's area may have an impact on the watershed's function. The Batulayar Sub-SMDI watershed's value in the SWAT Model results shows that it ranges from -0.50 to -2.99 in March, April, May, November, and December over a 10-year period, and is classified as "Slightly Dry" and "Slightly Dry." The Hydrological Model's role in determining the drought index can be seen in the results of calibration and validation using the NSE Model (Nash Sutcliffe Coeficient of Efficiency). An NSE value of 0.9 is obtained in calibration and validation, implying that the NSE value obtained belongs to the "good" class or that the discharge model and research observation discharge are similar.

Main objective of this study assess and evaluate energy literacy cognitive in difference system schools in Indonesia, namely are general public school, general private school, islamic public school and islamic private school based on scope of study and gender. A questionnaire was designed to check the cognitive to 64 students from four different senior high school. This study used frequency distibution and independent t-test as analysis and use SPSS software for helping calculating the questionnaires. The overall energy literacy cognitive level is dominant in very poor level (59.4%). One of the reason energy literacy in very poor level cause most of the parents' educational backgrounds are high school graduates (44%), also 41% their parents' educational backgroud are elementry and junior high school and there are only 13% in university. Students in general school study about energy three times in a week than in islamic school is just twice in a week. Therefore, it seems normal when energy literacy in general school is higher (mean value 34) than in islamic school (mean value 32) and it also happened between public school and private school, which public school has 35 and private school has 30. In science class, energy literacy is higher than social class that is caused students in science class study about energy on physics subject and chemistry subject, whereas in social class students study energy on geography, but it is not much as in physics and chemistry subject.

Justicia carnea and Cnidoscolus aconitifolius were tested for their capacity to ameliorate the fecundity of chloramphenicol-induced lymphoma in rats. Seventy male Wistar rats weighing an average of 128g were randomly divided into 14 groups of five rats each. Group 1 was provided with commercial rat diet and water on a daily basis. For 28 days, rats in groups 2-14 received 250mg/kg bodyweight chloramphenicol by oral intubation. Group 2 received no therapy and is thus referred to as the negative control group. The remaining groups (3–14) received aqueous leaf extracts of J. carnea (ALEJC) (Groups 3-6), C. aconitifolius (ALECA) (Groups 7–10), or a combination of both extracts (Groups 11–14) at dosages of 500mg/kg, 1000mg/kg, 1500mg/kg, and 2000mg/kg, respectively, for 28 days. After anaesthesia with ether, blood was drawn from the retro-orbital venous plexus to determine the activities of oxidative stress indicators such as superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and glutathione (GSH). The testes were dissected for histological inspection and the semen were collected for analysis. The results indicated a significant (p0.05) increase in weight across groups, as well as a reduction in sperm volume, viability, and motility in group 2 animals as compared to group 1. SOD and GSH levels increased significantly, but MDA levels increased in a non-significant (p>0.05) manner. The results indicated that the extracts had a beneficial impact on infertility associated with excessive chloramphenicol exposure.

Overweight, sedentary lifestyles, and some degree of insulin resistance are only a few of the traits linked with individuals who have the metabolic syndrome. Additional risk factors include a sedentary or inactive lifestyle, the use of psychiatric drugs, and excessive alcohol use. Weight gain and insulin resistance are connected with the metabolic syndrome. The most effective methods of losing weight are low-calorie diets and increased physical activity. Preliminary research indicates that individuals who consume a paleolithic diet may reduce three of the five quantitative risk factors for cardiovascular disease.

The purpose of this research was to assess the influence of nutritional premix on the growth and reproductive performance of confined Yankasa ewes. The experiment was designed using a Complete Randomized Design (CRD), in which twenty-five (25) Yankasa lambs were randomly assigned to five (5) treatment groups, each with five animals. The animals were randomly assigned to groups based on their weights and given baseline diets and four amounts of premix produced industrially and locally. Throughout the duration, 1 kilogram of basal feed (5 percent of the ewe's body weight) was supplied daily. Dietary premix was fed to the animals at four inclusion levels (0.25, 0.50, 0.75, and 1) in the morning in a restricted area; the amount of feed supplied and left over was recorded daily. The sheep were weighed at the start of the trial and then regularly afterwards. The study's results indicated that dietary interventions had an influence on final weight, total weight increase, and feed conversion ratio (P0.05). However, the dietary treatments had no significant effect on average daily weight increase, total feed intake, or average daily feed intake (P>0.05). Additionally, the findings indicated that when the amount of premix added to the diet rises, the final and total weight gain increases. The findings of T5 vary considerably from those of T1 and T2, but are statistically equivalent to those of T3 and T4. However, animals fed T5 (14.86) exhibited a higher feed conversion ratio (P0.05) than those fed T2 or T1.

Since the United Nations General Assembly passed two resolutions in December 1974, the term "desertification" has become a part of international development discourse: The first is a call to all countries to pay attention to desertification research and work together to explore its causes and find strategies to prevent it. The decision to organize an international conference on desertification in 1977 was the second. From August 29 to September 9, 1977, the conference was held in Nairobi, Kenya. The term "desertification" seems to have taken the place of prior words like "desert encroachment." Perhaps what we witness when desert sand dunes creep over oasis communities and farms and fill them, as well as when sand dunes crawl over paved highways and trains, contributes to this picture. This is a genuine depiction, however it only depicts a small portion of the problem (less than 10%). The word "desertification" refers to the process by which productive land outside of the desert's natural limits deteriorates and loses its capacity to produce (agricultural crops, pastures, timber and fuelwood) and transforms into a desert that resembles a limited resource. Desertification, in other words, impacts productive lands in dry and semi-arid locations, agricultural fields (rain-fed or irrigated), and grazing lands. The degradation begins as little patches that get larger and more like expanding patches until they converge and combine, becoming an arid band that joins the deserts of the surrounding places as it becomes more like them.

The research was conducted at the Suka Maju Farmer Group, Molamahu Village, Pulubala District in March 2020. The research objective was to determine the types of Refugia plants, production yields and farmers' income. This research was traced using descriptive methods for the use of refugia plants and t test to analyze farmers' income. The results of the research on refugia plants were beneficial for farmers as natural enemies of pests and there was an increase in the income of the Suka Maju Farmer Group after using refugia as a natural enemy of pests. The yield of maize by farmers who apply refugia plants is higher (10.51 tonnes / ha) than those using conventional methods (6.67 tonnes / ha) and there is a difference in income between farmers using conventional methods and those applying refugia plants. The income yield of farmers using refugia plants was higher (Rp. 33,523,200) than those using conventional methods (Rp. 21,169,920).
