Published: October 2019

ABSTRAK Energi yang berasal dari biomassa misalnya limbah baglog, yang selama ini dibuang atau tidak dimanfaatkan, merupakan limbah yang dapat dikonfersi menjadi sumber energi alternatif pengganti bahan bakar fosil. Limbah baglog jamur dimanfaatkan sebagai bahan bakar dengan cara, mengubah limbah tersebut menjadi biobriket. Tujuan penelitian dilakukan untuk pengkajian laju pembakaran, nilai kalor, kadar abu, kadar air, kadar zat yang menguap, kadar karbon dan drop test pada biobriket. Metode yang digunakan dalam pembuatan menggunakan perbandingan A (1:1:1) dengan komposisi tepung kanji 250 gram limbah baglog 250 gram dan air 250 ml, perbandingan B (1:2:2) dengan komposisi tepung kanji 250 gram limbah baglog 500 gram dan air 500 ml, perbandingan C (1:3:3) dengan komposisi tepung kanji 250 gram limbah baglog 1000 gram dan air 1000 ml. Pembutan yang pertama dengan penghancuran limbah baglog dan pengeringan, pencampuran tepung, limbah baglog dan air, pengepresan biobriket kemudian dikeringkan. Hasil penelitian memperoleh nilai kalor, kadar air, kadar karbon dan kadar zat yang menguap terdapat pada biobriket sampel A (1:1:1) sebesar 4065,69 kal/g, 5%, 15,4%, dan 71,4 % untuk kadar abu terbaik terdapat pada sampel B (1:2:2) sebesar 4,8%. Kata kunci: Limbah baglog, biobriket, bahan bakar fosil, jamur tiram ABSTRACT Energy derived from biomass such as baglog waste that has been disposed or not utilized, is a waste that can be converted into alternative energy sources of fossil fuel.

Authors: Supriyono Supriyono 
Published: October 2019

The aim of this research is to study the effects of pack carburizing using charcoal on properties of mild steel. The properties are represented by the results of microstructure, hardness test and tensile test. The carburizing process was conducted in the temperature of 930oC which is the austenite temperature of the mild steel. The source of carbon was charcoal. The specimens were held for 2, 3 and 4 hours at the carburizing temperature. The carbon content of the raw amterial was 0.17%. The raw material was hypoeutectoid steel with ferrite and pearlite phases in its microstructure. After the carburizing process, the microstructure can be divided into two zones e.i. case zone and core zone. The case zone consists of hypereutectoid, eutectoid, and hypoeutectoid sub-zone. The core zone is the same as raw material. The longer the holding time will result in the deeper the case zone and the stronger the material.

Published: October 2019

The use of technology in the search and delivery of tourism information is growing, although, on the one hand, the conventional tourism information media in the form of printed materials and audio-visual is still a popular source of information for tourists. The decision to visit a tourist destination can be influenced by various factors, one of which is the influence of stimulus from promotional media. Problems that occur, the study of the role of promotion from a comprehensive and integrated perspective has not been done much. Many promotions are interpreted as an effort to convey information to the stage of carrying out purchasing/travel activities. The purpose of this article is to analyze the perceptions of the academic community regarding the meaning of promotion through printed and audio-visual material for nature-based tourism in a comprehensive and integrated manner, as well as to determine the factors that influence decision-making by the academic community to actually visit nature-based tourism destinations. The distribution of questionnaires was conducted using a sample of academic community consisting of three categories, namely, lecturers, ecotourism students, and communication students with a total of 270 respondents to assess printed and audio-visual material. Data analysis was performed using One Score One Indicator Scoring System, Kruskal Wallis Test, and Dunn test. The results of the study show that tourism promotion can be effective and needs to implement seven phases of comprehensive and integrated promotion meaning. The opinions of the respondents of the academic community are not polar and illustrated the factors that influence the decision to do an actual visit. Factors that influence the form of psychological factors (motivation, the intensity of exposure to information about natural tourism), besides personal factors and demographic characteristics of respondents. The implications of this study regarding the promotion of effective nature-based tourism need to pay attention to tourist segmentation from various perspectives, both psychological, personal, environment and demographic, especially the promotion of nature-based tourism, besides implementing promotion in the context of more comprehensive and integrated meaning to run more effectively.

Authors: Ningrumsari Ida 
Published: October 2019

The study aimed to evaluate the administration of L acidophilus in fermented feed to improve the quality of broiler chicken meat (Protein, Cholesterol) which was maintained for 35 days. The material used is 100 chickens that are 1 day old (DOC). The experiment used a laboratory experimental method with a non-factorial Completely Randomized Design with a treatment level consisting of feed type Ro = standard feed, R1 = R0 + Fermented corn husk 10%, R2 = R0 + Fermentation of 20% corn husk, R3 = R1 + L acidophilus 2% and R4 = R2 + L acidophilus 2%. Each treatment was repeated 4 times and each replication contained 5 chickens. The results of analysis of variance showed that administration of L acidophilus in fermented feed significantly affected the increase in protein (R1) and decreased cholesterol (R3) with an alpha level of 5%. The average protein content R1 = 21.8000 was not significantly different from R4 = 21.5500, while R2 = 21.0500 was significantly different from R3 = 20.6500 and R0 = 20.2000. The lowest average cholesterol level is found in R3 = 64,000 and the highest at R0 = 96,500. While the cholesterol levels R1, R2, R3 and R4 were not significantly different, but were significantly different from R0.

This research method uses true experimental design, randomized pretest posttest design. Sampling technique with simple random sampling. intervention group I was given aromatherapy cananga and group II was given lavender aromatherapy. Changes in pain intensity are measured using a Numerical Rating Scale. The pain felt by patients before inhaling cananga aromatherapy is an average of 5.00 (moderate pain) and after therapy of 3.25 (mild pain). Pain that was felt by patients before inhaling lavender aromatherapy was an average of 4.83 (moderate pain) and after therapy of 3.25 (mild pain). The results of the analysis with the Wilcoxon test (p value 0,000) showed that there was an influence of cananga and lavender aromatherapy interventions using inhalation techniques to the intensity of pain in post sectio caesaria patients. Mann Whitney Test results obtained p value 0.054. Conclusions There is no significant difference in the effect of intervention from the two groups, meaning that both interventions have the same effective effect in reducing the intensity of pain in post-sectional cesarean patients.
