Abstract

Problem based learning (PBL) aims to form student’s problem-solving, which require ananalysis, evaluation, and creation abilities (Higher order thinking or HOT). Implementation of PBL is often used, but has not been analyzed based on syntax and its characteristics. The sample of the study consisted of 53 students divided into two classes XI MIPA 1 and XI MIPA 4. Data sources include the observation’s results of learning in the classroom, student feedback questionnaire, student answers on questions HOT, teacher’s questionnaires and interviews. Data were analyzed by descriptive percentage and pearson correlation.  The result showed that all phases of PBL’s syntax is well implemented. The investigation, development & presentation, and the analysis of the problem-solving process are well implemented, but it is excellent on student organizing and problem-orientation phases. As much as of 20,13% of students had an ecxellent HOT, 57,86% is good, 16,98% is fair, and 5,03% is poor. The correlation between PBL implementation and HOT capability is 0,36 which is categorized positive but weak.

Abstract

Technology growing rapidly because technological development is required in all aspects of humanlife. Biotechnology is one of the branch of biology that is constantly evolving. Health andpharmaceutical biotechnology is one of the biotechnology which became the spotlight of the world.Biotechnology is part of science that commences from curiosity. One of curiosity type is epistemiccuriosity (EC). Epistemic curiosity contribute to give problem solving for the appearing issue. Thisneed higher order thinking. Higher order thinking need good cognitive understanding. The purpose ofthis study is to: 1) describe the epistemic curiosity (EC) Biology’ student to the development of healthand pharmaceutical biotechnology, 2) analyzing the correlation of epistemic curiosity (EC) andcognitive ability of biology’ student in health and pharmaceutical biotechnology. This researchincludes descriptive correlative with the research data is a cognitive understanding and EC ofbiology’ student.

Abstract

Feronia limonia (L.) Swingle better known as wood apple is an identity plant of Rembang Regency, Central Java Province, Indonesia. However, the population is very limited. In order to identify the conservation efforts, this ethnobotany study was aimed to determine traditional knowledge on the existence, economic value, utility, breeding technique and conservation of wood apple. The survey was conducted on a total of 102 local people from 10 sub-districts which were determined by proportionally stratified random sampling. Data were collected by questionnaires and individual interviews and then were analyzed descriptively. The results showed that all of respondents knew the figure of wood apple, but only 79.50% understood its status as an identity plant. Most of respondents (96%) stated that the fruits have low economic value, 80.39% respondents have utilized ripe fruit as ingredients of beverages and stems as firewood. This utilization was only equal to 29.72% compared to the potential usability based on research results. It was concluded that the traditional knowledge about the existence, economic value, and breeding technique were good and on the contrary, the knowledge about the plants usability was bad. The results will form a basic knowledge for in-depth studies to provide a government policy of Rembang Regency in order to develop an efficient strategy of management and conservation of wood apple as plant identity.

Abstract

The research aimed to compare caulifl ower growth and production planted at lowland and highland by using organic farming system. The research was single treatment experimentally, which was land height, consisted of highland (Kopeng) and lowland (Ambarawa). The variables were vegetative growth (leaves amount and plant weight) and generative development (fl ower initiation and fl ower weight). The data were analyzed by t-test. The result confi rmed that organic farming will make better lowland caulifl ower vegetative growth but least generative development compare to the highland one. It can be concluded that caulifl ower have the potency of being growth at lowland, even though with least yield.Keywords: lowland, highland, caulifl ower, organic

Abstract

TK Wiji is a nursery school which was built at Jl. Untung Suropati no. 10  kelurahan Tegalrejo kota Pekalongan based on NPSN 69879295 of 2005 by Yayasan 99. TK Wiji is growing fast due to its education system which is in line to the 2013 national curriculum with the vision of toodler characteristic development. The most fundamental of character education is environment education. Considering to this situation, we have found that the most common litter of the nursery is disposable diaper. This kind of diaper is hardly degraded into its monomer. Colon’s research in 2013 has found a strategy to use this diaper as compost. Based on the problem of disposable diaper wastes in the nursery and also the result of the background research about exploiting the waste as compost, then the environment education for toodler of TK Wiji by using diaper waste as a material for hidroponic cultivation was done. In the beginning, guidances were given to the teacher in 2 phases which are making diaper waste composite into organic fertilizer and making hidrogel for interior plant cultivation by using the gel of the waste. In the next step, the teachers were asked to make improvisation regarding toodler environment education by using the skills. In spite of this, there was still an argument about the time management in the learning process by using diaper waste as the material. Thus an implementation of the skill for toodler extracuricular was stated.

Abstract

Anggrek merupakan tanaman dengan nilai ekonomis tinggi. Pemeliharaan anggrek memerlukan peralatan dan ketrampilan khusus supaya dapat tumbuh dan berkembang dengan baik. Griya anggrek Mekar Sari merupakan salah satu rumah anggrek di wilayah Kalisegoro yang mempunyai potensi besar untuk berkembang. Pengembangan rumah anggrek ini terkendala adanya kurangnya sarana dan keterampilan pengelola dalam budidaya anggrek maupun pemasaran anggrek. Saat ini peralatan yang digunakan masih sangat terbatas. Selain itu pengadaan pupuk dan juga pembasmi hama juga masih terkendala oleh dana. Perawatan anggrek saat ini hanya berkisar penyiraman saja karena masih terbatasnya pengetahuan dan ketrampilan Ibu-Ibu PKK RW 4 Kalisegoro. Dukungan untuk mengatasi hal tersebut perlu adanya penyediaan alat dan bahan yang bekaitan dengan budidaya anggrek, pelatihan mengenai budidaya anggrek dan pelatihan pemasaran anggrek. Strategi pemasaran anggrek akan didukung dengan pembuatan web Griya Anggrek Mekar Sari sehingga Griya Anggrek Mekar Sari tidak hanya dikenal di sekitar lingkungan Kalisegoro tetapi juga daerah lain. Web Griya Mekar sari telah berhasil dikembangkan. Penambahan koleksi anggrek, peralatan dan juga bahan untuk pemeliharaan anggrek meningkatkan kualitas dan kuantitas anggrek. Peningkatan kualitas dan kuantitas anggrek serta adanya strategi pemasaran meningkatkan omzet penjualan anggrek. Selain itu keterampilan peserta juga meningkat dengan adanya pelatihan persilangan anggrek dan tambahan pengetahuan berkaitan dengan display anggrek pada showroom.
