Directional felling is a technique that directs fallen trees in a predetermined direction to minimize damage to residual stands and understory plants and facilitate subsequent stages of timber handling. One of the felling techniques used in private forest harvesting was the rope-assisted directional felling technique. The study aimed to analyze and evaluate the effectiveness of the rope-assisted directional felling technique in private forests. The study was conducted in a private forest managed with an agroforestry system in Probolinggo, East Java. The number of sampled trees was 31 trees. The sampled trees were felled to the predetermined directions: to a stretched rope between two spar trees or the safe area. Felling errors, hang-ups, and the presence of barber chairs were used to assess the effectiveness of the rope-assisted felling technique. The average diameter of the felled trees was 23.4 cm and  20.8 m in height. The ropes-assist directional felling technique produced a hang-up tree of 19.35% of the total felled trees. Directional felling using ropes made fallen trees from close to the opposite direction of the natural felling direction.  The ropes-assisted felling technique made all felled trees fall in the predetermined direction without producing barber chairs, but still causing hang-ups.

The urgent need to deal with specific environmental changes globally has made us aware of the importance of environmental literacy skills to achieve new relationships with the environment. This study examines and discusses the development of prospective teachers' environmental literacy. It also seeks to link the findings of the educational environment and the environmental impact of pre-service teacher environmental literacy education to the SLR approach. The literature search was conducted online in the Scopus-indexed database with “environmental literacy” and “pre-service teacher” assisted with Publish or Perish software. Then, the search results found 48 articles, followed by a procedure that included Identification, Screening, Eligibility, and Inclusion for each article. Fourteen articles fit the category, so an in-depth analysis was carried out regarding the application of environmental literacy to the prospective teacher education curriculum. The findings show prospective teachers are primarily concerned with environmental issues; however, this emotional reasoning or treatment perspective does not always translate into engaging behaviors or actions. The complexity of environmental problems makes it difficult for prospective teachers to identify how to be involved in this environmental action. Environmental learning to develop environmental literacy can be applied to the curriculum of prospective teachers. Prospective teachers have enormous potential to influence, providing examples and being role models for students in protecting the surrounding environment.

In the short term, children will be at risk and susceptible to infectious diseases, while in the long term, in adulthood they will be at risk of suffering from chronic diseases. Low income affects household nutrition. The incidence of stunting cannot be separated from habits, cultural beliefs, knowledge and perceptions of local communities regarding fulfilling family nutrition. These beliefs have an influence on child care. The aim of this research is to identify the role of fathers in the incidence of stunting in South Central Timor Regency. This type of qualitative research uses focus group discussion (FGD) methods and in-depth interviews. The respondents involved for the qualitative approach were government figures (village heads and sub-district heads), religious leaders, traditional leaders, health services, community health centers and fathers with toddlers totaling 7 people from each village. The results obtained on average are that fathers know the direct causes of stunting, not because of their knowledge but because fathers are less aware of their child's parenting patterns. Parenting patterns regarding monitoring children's meal times, personal hygiene and providing diverse and nutritious food are lacking. On average, a father is busy earning a living, many even work outside the city so their children are entrusted to their grandparents, there is a lack of control in the family so there are many early marriages under the age of 20, the family economy is weak so people have less purchasing power to earn money. nutritious food ingredients. The conclusion from this research is that the role of fathers is one of the causes of stunting in South Central Timor Regency.

DNA isolation is an important step for further molecular analysis. Coffee plants contain polysaccharides, polyphenols, and secondary metabolites which can contaminate the results of DNA isolation. This study was conducted to isolate DNA from arabica and robusta coffee leaves using a modified CTAB method and PCR optimization for amplification of matK and rbcL genes. DNA was isolated using buffers (CTAB 10%, PVP 1%, β-mercaptoethanol 1%, Tris-HCl 1M, NaCl 5M, and EDTA 0.5%), and eluted with TE-RNase. Genomic DNA of ten coffee plants was successfully isolated with concentrations ranging from 33-146 nm/µL with purity (A260/A280) 1.7-1.9. Based on the genomic DNA isolated, matK and rbcL  genes were amplified with initial denaturation conditions of 94°C (for 1 minute of matK and 4 minutes of rbcL) followed by 35 cycles of denaturation at 94°C for 30 seconds, annealing (adjusted to each primer), and extension at 72°C for 1 minute. The optimal PCR conditions were effective to amplify matK (900 bp) and rbcL (600 bp) genes. Thus, the modified DNA isolation method and PCR optimization can be used as an efficient tool for further molecular analysis of Coffea arabica L. and Coffea canephora Pierre ex A. Froehner.

Authors: Zali Moh
Published: September 2024

This study investigated the effects of bamboo leaf supplementation on nutrition intake, productivity, and growth performance in Boer goats (Capra aegagrus hircus). A randomized complete block design was employed, with four treatment groups: Control (no bamboo leaf supplementation) and three experimental groups receiving Low Dose (50g/day/goat), Medium Dose (100g/day/goat), and High Dose (150g/day/goat) of bamboo leaves. Each treatment group comprised three repetitions. Thirty-six healthy Boer goats of similar age and weight were selected and housed individually with ad libitum access to water and a basal diet. Bamboo leaf supplementation was administered daily for 60 days, following which nutrition intake, productivity, and growth performance were assessed. Results revealed a dose-dependent increase in nutrition intake with higher levels of bamboo leaf supplementation, indicating improved feed consumption in supplemented groups. Productivity, measured as total weight gain per hectare, exhibited a similar trend, with the Medium and High Dose groups demonstrating higher productivity compared to the Control and Low Dose groups. Analysis of growth performance, represented by average daily gain (ADG), further supported these findings, showing higher ADG in the Medium and High Dose groups. Bamboo leaf supplementation positively influenced nutrition intake, productivity, and growth performance in Boer goats. These results suggest the potential of bamboo leaves as a valuable dietary supplement for enhancing goat farming efficiency and livelihoods, particularly in regions where bamboo is abundant.

The prevalence of malaria in East Nusa Tenggara based on positive diagnosis results containing malaria parasites and symptoms in the 2013 - 2015 period decreased but has not yet reached the National Strategic Plan target, namely in 2013 it was 21 per 1,000 population (o/oo), in 2014 it was 14 o/oo, and in 2015 it became 8 o/oo (NTT Health Office, 2016). In 2017 there was a spike in malaria cases to 211,409 cases (API = 44.96 o/oo). Kupang Regency with 1,108 cases (API = 24.87 o/oo). Malaria cases in the Tarus Community Health Center work area are the eighth highest, namely 7 cases. This study aims to analyze the effectiveness of insecticide-treated bed nets on the death of Anopheles subpictus mosquitoes. The variables observed were the length of time the mosquito net was used, the frequency of washing the mosquito net, the method of washing the mosquito net, and the percentage of Anopheles subpictus mosquito deaths. The effectiveness of insecticide-treated bed nets on the death of Anophles subpictus mosquitoes with usage time < 3 years (100%), usage time 3 – 5 years (70%) and usage time > 5 years (40%). The effectiveness of insecticide-treated bed nets that have never been washed reaches 100% mortality within 24 hours of observation. Meanwhile, mosquito nets with a washing frequency of 1 – 10 times (70%) kill mosquitoes, and a washing frequency of > 10 times (50%). The method of washing mosquito nets carried out by the community in the Puskesmas Working Area is 100% using detergent. In the control group that used mosquito nets that did not contain insecticide, no Anopheles subpictus mosquito deaths occurred (0%). Suggestions for health workers to increase education regarding the correct use of mosquito nets, so that a higher level of effectiveness of mosquito nets is obtained as a means of personal protection in avoiding mosquito bites.
