Abstract
Accuracy of data and information on various types of land use and land cover (LULC) is crucial in watershed management planning. The development of remote sensing technology in predicting LULC has been widely used, such as the Support Vector Machine (SVM) and Random Trees (RT) methods. Both methods are part of the model of machine learning and belong to the category of supervised learning. This method can predict, study, and recognize data patterns from the results of training data. The aim of this research is the use of SVM and RT methods for the identification of LULC. Based on the SVM method analysis results, the forest area is 211.61 km2, coffee plantations are 32.92 km2, shrubs are 16.85 km2, built-up/bare land is 3.40 km2, the water body is 3.17 km2, and cloud/shadow is 6.79 km2. While the RT method obtained a forest area of 215.51 km2, coffee plantations covering an area of 29.32 km2, shrubs are covering an area of 16.32 km2, built-up/bare land surrounding an area of 7.22 km2, water body covering an area of 2.62 km2, and cloud/shadow covering an area of 3.75 km2. Overall, the percentage accuracy of the SVM method of 87%, and the RT of 86%. The success rate of modeling SVM (AUC = 0.73) and RT (AUC = 0.75) based on the results of data validation using the area under the receiver operating characteristic curve (AUC) was considered fair good.

AbstractOil palm is the leading plantation commodities in Bengkulu province which is able to increase original local government revenue. Besides producing palm oil, this plant also produces solid waste, fronds, and leaves. The purpose of this study was to determine the response of Bali cattle fed by oil palm waste. The research was conducted from August to November 2018 in Margo Mulyo village, Pondok Kubang subdistrict, Central Bengkulu regency, using 2 treatments (introduced and existing) with 13 replications. The composition of introduced feed is forage (70% field grass + 30% fermented fronds and palm leaves) + fermented solid as concentrate. Existing feed composition is field grass (forage) + rice bran (concentrate). Forage is given 10% and concentrate 1% of body weight. The parameters observed were body weight gain and Body Condition Score (BCS) and analyzed by T-test. The results showed a significant effect of treatment on body wight gain. The introduction treatment was able to produce body weight gain by 0.33 kg/head/day, while the existing treatment produce body weight gain of 0.17 kg/head/day only. BCS score of Bali cattle in both treatments not significantly different at the beginning was 2-3 and in the end 3-4, categorized in medium conditions.

AbstractInvestigating the effect of safflower oil (Carthamus tinctorius L) and inositol on the quality of Sentul chicken eggs. Eight one 16-week female Sentul chickens were distributed to 81 units of battery cage (3 chickens each). Basal diet was composed of corn, rice bran, soybean kernel, fishmeal, palm oil, calcium car-bonate (CaCO3), topmix, lysine and methionine, as well as safflower oil (Car-thamus tincthorius L) and inositol. The research was conducted in a Completely Randomized Design (CRD) with 9 treatments and 3 replicates (3 chickens/unit). The treatments were R0 = Control/basal diet + 0% Safflower and 0% Inositol; R1 = Basal diet + 0.5% Safflower oil; R2 = Basal diet + 1.0% Safflower oil; R3 = Basal diet + Inositol 0.5%; R4 = Basal diet + Inositol 1.0%; R5 = Basal diet + 0.5 % Safflower oil + 0.5% Inositol; R6 = Basal diet + 0.5 % Safflower oil + 1.0% Inositol; R7 = Basal diet + 1.0 % Safflower oil + 0.5% Inositol; R8 = Basal diet + 1.0 % Safflower oil + 1.0% Inositol. The data were subjected to analysis of vari-ance (ANOVA), continued with an Honestly Significant Difference test (HSD) using SPSS ver. 17.0 with 5% error. The result showed that supplementing saf-flower oil (Carthamus tinctorius L) and inositol in feed did not significantly af-fect (P>0.05) egg weight, egg index, fat and cholesterol content of egg yolk, but significantly affected (P<0.05) egg yolk protein, and most significantly affected (P<0.01) egg production. Conclusively, supplementing 1% safflower oil in feed could increase egg production, but 1% safflower oil 1% + 0.5% 0.5% inositol could increase protein as well as decreasing fat and cholesterol of egg yolk.

Abstract
Methane emission from ruminants can be mitigated with supplementation of medium chain fatty acids (MCFA) such as lauric acid that present in coconut oil. However, the effects of coconut oil supplementation on in vitro rumen fermentation and methane emission have been varied. This study was conducted to examine the effect of dietary coconut oil supplementation on rumen fermentation and methanogenesis by integrating data from various in vitro studies. A linear regression statistical model approach was applied to a total of 14 studies and 38 data points. The response variables integrated were methane emission, fermentation products, nutrient digestibility, and microbial population. The data obtained were analyzed by using IBM SPSS software version 20. The results showed that methane production was decreased significantly (P<0.01) by supplementation of coconut oil. Coconut oil tended to decrease methanogenic archaea, protozoa, total volatile fatty acids and isovalerate proportion (P<0.1). However, the oil supplementation did not significantly affect dry matter digestibility, total gas production, N-ammonia, acetate, isobutyrate, valerate, acetate to propionate ratio, population of rumen bacteria, organic matter digestibility, pH, propionate and butyrate. It can be concluded that coconut oil supplementation is able to mitigate methane emission by modifying microbial population structure and fermentation in the rumen.

Published: June 2022

Abstract
Arabica coffee leaf extract (Coffea arabica L.) contains phenolic and flavonoid compounds that are potentially active as sunscreen because it might absorb UV (Ultra Violet) A and UV B rays. It is well-known that UV rays exposure causes a negative effect to skin, yet is possible to be avoided by applying sunscreen. This research aims to test the effect of arabica coffee leaf extract on formulation of gel preparations and to discover how its concentration affects the amount of gel preparations’ sunscreen factor. There were 4 formulas with different extract concentrations whose characteristics were tested chemically, physically, and they were tested to measure its SPF number. From this test, it was discovered that the gel was qualified and it was plastic thixotropic flow. The measurement of SPF number proposed that F1 could not be categorized as protector because it was only 0.6 while F2, F3, and F4 showed that these formulas could be categorized as minimum protector. The samples were also tested statistically by using One Way ANOVA and Tukey HSD test. The result of the ANOVA test showed the number of sig 0.000 < 0.05 which meant all four formulas were significantly different. The research concludes that the extract of arabica coffee leaf might affect the formulation of gel preparations and its extract concentration might affect SPF number on gel preparations.

Abstract
The screening process to detect early-stage lung cancer is injurious to a patient’s survival. Fortunately, there are natural compounds that have been acknowledged to possess anticancer properties, work as the protein binding inhibitors of lung cancer promotors: EGF and EGFR. The study aims to identify inhibitors of EGFR protein binding. Assessments were accomplished based on several parameters related to EGFR proteins, such as pathways, protein activity, conformational changes, and numerous information using the STRING database and KEGG pathway database. Ten inhibitor compounds that expressed highest activity were selected for further analysis were: (20R,22R)-5beta,6beta-Epoxy-4beta,12beta,20-trihy-droxy-1-oxowith-2-en-24-enolide, irinotecan, flavopyridol, teniposide, exatecan, daphnoretin, indirubin, topitecan, wentilactone, and evidiamine. The native ligand Lapatinib was used as positive control in this analysis. The analysis was accomplished by molecular docking using Vina 4 in the PyRx software. Interactions between the ligands and residues were investigated using LIGPLOT+ 2.2. The In-silico analysis of the ten candidate compounds revealed that (20R, 22R)-5beta, 6beta-Epoxy-4beta, 12beta, 20-trihydroxy-1-oxowith-2-en-24-enolide expressed the lowest binding energy value, which is -10.4 kcal/mol, indicated the closest binding energy value to Lapatinib as the control. Based on the interaction of amino acids, (20R,22R)-5beta, 6beta-Epoxy-4beta, 12beta, 20-trihydroxy-1-oxowith-2-en-24-enolide has excellent potential to be utilized as next inhibitor com- pound candidates for EGFR protein, because it binds to the Lys745 residue. It mirrors the positive control and has a binding energy on the range of the specified acceptable parameters.

Authors: Sumarmono J 
Published: June 2022

Abstract
In Indonesia and some southeast Asian countries, the number of goats raised for milk production is growing. In these countries, goat milk is the second most produced and consumed milk after cow milk. In Indonesia, dairy goats’ development is promising, but the farming of dairy goats and marketing milk products is still scattered and unstructured. The milk is produced from varieties of goat breeds, including Peranakan Etawa, Saanen, Nubian, and their crosses. Goat milk has unique and distinct characteristics and is an excellent source of nutrients for humans. Compared to cow milk, it has smaller fat globules, more homogenous, shorter rennet coagulation time, and softer curd. Goat milk utilization includes fluid milk for direct consumption; frozen fresh milk; dried or powdered milk; fermented milk products such as yogurt, kefir, including its derivatives such as cosmetics, concentrated yogurt, yogurt cheese, ice cream, shakes; cheeses such as fresh cottage-type cheese, acid-coagulated cheese and mozzarella; and also, other traditional products such as sweets & candies and caramels. The development of dairy goats and goat milk consumption is driven by several factors, including the low cost for start-up and production, consumers’ demand, alleged health properties of goat milk, and varieties of products.

Abstract
Both the vibration and backwashing methods are efficient pathway to improve the denitrification ability in reactors. However, the comparison of the effects of vibration and backwashing on the sulfur-based autotrophic denitrification (SAD) reactor is still lacking. In this study, two SAD reactors were compared under various conditions, and the results showed that the use of the oyster shell powder could lower the sulfate productivity with better denitrification ability, and the denitrifiers could be more enriched due to the use of the oyster shell powder. In addition, vibration method performs better than backwashing in improving SAD denitrification ability, reasonable vibration intensity can not only help to reduce energy consumption, but also improve the ability of denitrification of the SAD reactors to a greater extent. Overall, the results of the experiments in this study are helpful for improving the ability of SAD reactors at low temperature and could provide the possibility for wider application of SAD technology.

Abstract
We propose and numerically investigate an angle-tuned polarization-independent multi-narrowband perfect absorber, which comprises a simple gold nanocube array on SiO2/oxidized aluminum mirror layers. The oxidized aluminum mirror is able to support the surface plasmon polariton mode on the SiO2/Al2O3 interface. The multi-narrowband absorption contributes to the simultaneously excited quasi-metal–insulator–metal guided modes and standing wave cavity mode in the thick insulator layer by the incident light normal to the structure in the wavelength range 1400–2400 nm. Moreover, the absorption can be actively modulated by adjusting the incidence angle, and it is polarization independent. The perfect absorber is also suitable for sensing, with the figure of merit reaching 102 RIU−1 within the refractive index range from 1.3 to 1.36.

Published: June 2022

Abstract
Continuous variable quantum key distribution (CV-QKD) is a promising emerging technology for the distribution of secure keys for symmetric encryption. It can be readily implemented using commercial off-the-shelf optical telecommunications components. A key requirement of the CV-QKD receiver is the ability to measure the quantum states at the correct time instance and rate using the correct orthogonal observables, referred to as synchronization. We propose a digital synchronization procedure for a modern CV-QKD system with locally generated local oscillator for coherent reception. Our proposed method is modulation format independent allowing it to be used in a variety of CV-QKD systems. We experimentally investigate its performance with a Gaussian modulated CV-QKD system operating over a 10–20 km span of standard single mode fibre. Since the procedure does not require hardware modifications it paves the way for cost-effective QKD solutions that can adapt rapidly to changing environmental conditions.
