Published: February 2020

Abstract
One of the successes of a construction operation is determined by the service provider as the executor of construction activity so that the competency of the service provider will determine the implementation of construction activities. The performance of construction work is said to be good if it meets the time, quality and costs following the contractual agreement that has been agreed with the service user. The Occupational Health and Safety Management System is one of the determining factors in construction work that is still not considered by a Construction Services Business Entity in Indonesia. Existing regulations and laws have heavily regulated performance appraisal indicators related to the implementation of the Occupational Health and Safety Management System. This study tries to look at the effect of the assessment indicators on the implementation of the Occupational Health and Safety Management System that has been regulated in existing regulations to small business entities to be able to see the effectiveness of existing regulations and can be input to existing regulations related to the assessment of construction services small qualification construction services business entity.

Abstract
Response of flowering has become an attracting field for plant breeders and is pre-requisite in plant introduction process from different ecogeographical origins. Time of flowering is mostly induced by the day-length or photoperiod and temperature. Amaranth (Amaranthus sp.) is known as multipurpose plants and utilized as grains or as vegetables. Under tropical environment, likewise in Indonesia, the requirement of day-length to induce flowering in amaranths is unrevealed as the day-length remains always constant with approximately 12 hours per day. During the introduction of amaranth to Japan, we would like to confirm the type of amaranth, which in general has been theoretically classified as short day plants. Under the variation of day-length ranging from 9 up to 15 hours during the four seasons in Japan, thus, we confirmed that amaranth as short day plants. Although, the vegetable ones required day-length up to 12 hours. Such conclusion was obtained from the flowering response of 69 accessions representing amaranth’s eco-geographical variations within two consecutive years. Seeds were sown in two replicates. Plant nursery was conducted on the Norin-Ijutsu Centre belongs to the University of Tsukuba. Mean values from two replicates were obtained and the average was then further subjected to Principle Component Analysis (PCA) [JMP ver. 7.0 (SAS Institute, USA)]. Thus, PCA was able to differentiate the flowering tendency within the three types of amaranths in the form of three ellipsoids.

Abstract
Kebonpeuteuy Village is located at the foot of Mount Gede Pangrango. The existence of a Bottled Drinking Water Plant in this region raises a crucial issue dealing with the decrease of clean water supplies for the villagers, especially in hamlet 1. This study produces a number of confirmations: (1) during this time the distribution of the availability of clean water in this village has been ensured with a reservoirs system or water tanks and pipelines; (2) the existence of this plant does not have a direct influence on the sustainability of clean water availability in this village because the plant only takes ground water instead of surface water; (3) there is a significant change related to safeguarding the sustainability of the availability of clean water after the application of the recommendations from LKMM research, in the form of making water banks, planting trees along the watershed, making bio-pores and several other infiltration wells; and (4) related to the status of the operation of the drinking water business according to Islamic law, the drinking water plant only takes ground water from a depth of 60-90 meters and does not obstruct the rights of other parties who also want to access the groundwater source in other locations. For this result, it is recommended that the involvement of all village development stakeholders, including the educational institutions and drinking water plants to educate all the villagers to strengthen the independent mental attitudes, self-assessment capabilities and problem solving so that the availability of clean water can be carried out independently. Especially, the plant managers of the drinking water are required to increase transparency in the groundwater extraction process to settle the issue of the exploitation of surface water by the drinking water plant and to prevent the emergence of things considered counterproductive from the community.

Published: February 2020

Abstract
Differences in can dimension, filled volume and type of sterilization equipment affect the heat penetration rate, temperature and time required for sterilization process in canned food. Thus, careful calculation and decision for those factors are critical to determine the final product quality. Therefore, this research aimed to investigate the quality of canned yellowfin tuna in a specific can dimension using a 24 L pressure canner by applying different time and temperature combination i.e., sterilization at 121°C for 20 minutes and at 115°C for 50 minutes. Two type of mediums used were palm oil and brine. Heat penetration study and calculation of sterilization time (Fo value) were conducted using thermocouple data logger for both methods. The results showed that the protein content decreased slightly from 24.6% (fresh tuna) to 23,57% (canned tuna sterilized at 121°C for 20 min) and to 13,31% for canned tuna sterilized at 115°C for 50 min. There was a sharp increment obtained for fat content of canned tuna in palm oil (0.54% to 10.6%). Heat penetration study indicated that the Fo for canned tuna in brine were longer (30.13 minutes) than tuna in oil (20.09 minutes). This research suggests that sterilization of canned tuna is recommended to be done at 121°C for 20 minutes with regards to the nutritional content of the final product, particularly the protein content.

Published: February 2020

Abstract
Based on Indonesia Program for Pollution Control, Evaluation and Rating (PROPER), palm oil industries are more likely to care about hazardous waste management rather than resource efficiency. It is very important to balance and achieve economic and ecological targets by identifying material and energy inefficiencies with significant economic impact. The application of standard and sustainable production also plays important role for oil palm companies which so far have more than 70% of biomass energy materials such as shells, powders, fibres, and dried empty bunches. This study used the production cost approach and material flow cost accounting to reduce material consumption and waste minimization. Identifying resource efficiencies were used to determine area for improvement. The results show that palm oil company more likely to manage total waste, hazardous waste, and raw materials consumed than material efficiencies. In terms of financial factors, cost ratio and profitability are likely to affect firm decisions regarding to manage the material flow for reducing hazardous waste ratio. This could support long-term business relationships which can be established and negotiated between the palm oil industry as organic waste supplier and the bioenergy producer, revealing economic and environmental benefits for both actors while contributing to the development of responsibility, effectiveness and sustainable (RES).

Authors: Bata M , Rimbawanto E A , Rahayu S 
Published: February 2020

Abstract
The aim of this study was to find the optimal level of urea-zeolite supplementation in the substrate on rumen fermentation products and digestion in vitro. Testing the solubility level of urea-zeolite at a ratio of 1: 1 and 1: 2 in rumen fluid based on N-NH3 levels was carried out at the fermentation time of 0, 1, 2, 3, 4, and 5 hours. Completely randomized design was used in this research with urea-zeolite supplementation treatment (0.2, 4, 6, 8, and 10% of dry matter (DM) substrate). Substrate composed of corn sugarcane silage and concentrate with DM ratio was 70%: 30%. The variables measured were rumen fermentation products (pH, VFA, and N-NH3), DM and organic matter (OM) digestibility. The results showed that the solubility of urea-zeolite in rumen fluid at the same ratio of 1: 1 and 1: 2, the highest at 4 hours fermentation time of 40.81% and 39.13% and after 4 hours was stable. Urea-zeolite supplementation (ratio 1: 2) on the substrate has no effect (P> 0.01) on the pH of the liquid. N-NH3 fermentation products increased (P <0.01) linearly with increasing levels of urea-zeolite supplementation. The total VFA product and the degradation of dry matter were highly significant (P <0.01) influenced by urea-zeolite supplementation and were optimal at 6% and 4% DM substrate supplementation, respectively. DM and OM digestibility was highly significant (P <0.01) influenced by urea-zeolite supplementation and was optimal at the 6% BK substrate level. It was concluded that the use of urea-zeolite as a supplement in the substrate could increase fermentation products and digestibility in vitro
