ABSTRAK Penelitian ini bertujuan untuk mengetahui (1) Proses kerjasama petani kakao dengan PT. TMCI menjadi fokus penelitian ini. (2) Perbedaan output dan pendapatan antara petani kakao nonmitra dan mitra di PT. TMCI, dan (3) Produksi dan pendapatan petani kakao mitra dan non mitra di PT. Populasi penelitian sebanyak 1.277 petani kakao yang terdiri dari 30 petani mitra dan 30 petani non mitra yang dijadikan sampel penelitian. Karena jumlah sampel yang sama di Kabupaten Lalembuu, maka digunakan sampel acak sederhana untuk penelitian ini. Hasil penelitian mengungkapkan bahwa (1) proses kemitraan di PT. TMCI menunjukkan bahwa kualitas biji kakao memenuhi kriteria, sertifikasi perkebunan, dan pembentukan kelompok tani. Mengisi dokumen dan menandatangani kontrak kerjasama adalah salah satu langkah dalam prosesnya. (2) Rata-rata hasil tahunan petani kakao responden 974 kg per hektar, sedangkan responden nonmitra 908 kg per hektar. Pendapatan tahunan rata-rata responden mitra adalah Rp26.863.114, sedangkan responden bukan pasangan sebesar Rp22.161.946. (3) Terdapat perbedaan yang cukup besar dalam tingkat kepercayaan antara hasil dan pendapatan petani kakao mitra dan non mitra, yang menunjukkan bahwa terdapat perbedaan produksi antara petani kakao mitra dan non mitra. Jelas dari temuan penelitian di atas bahwa perusahaan PT TMCI memiliki pengaruh terhadap kemitraan dengan membantu petani belajar lebih banyak dengan mengarahkan proses penanaman kakao. Selain itu, ini dapat meningkatkan output dan menghasilkan pendapatan mitra. Kata kunci: Kemitraan, Produksi, Pendapatan, Dampak, Kakao ABSTRACT In this investigation, we'll find out (1) The collaboration process of cocoa growers with PT. TMCI is the focus of this research. (2) Differences in output and income between non-partner and partner cocoa farmers at PT. TMCI, and (3) Production and income of partner and non-partner cocoa farmers at PT. The study's population of 1,277 cocoa growers included 30 partner farmers and 30 non-partner farmers who served as research samples. Because there are an equal number of samples in the Lalembuu District, simple random sampling was used for this investigation. The findings revealed that (1) the partnership process at PT. TMCI demonstrates that the cocoa bean quality satisfies criteria, plantation certification, and the establishment of farmer groups. Filling up documents and signing collaboration contracts are among the steps in the process. (2) The average output of cocoa farmer respondents is 974 kg per hectare, while that of non-partner respondents is 908 kg perhectare. The average annual revenue of partner respondents is Rp26,863,114, while that of non-partner respondents is Rp22,161,946. (3) There is a significant difference in the confidence level between the results and income of partner and non-partner cocoa farmers, indicating differences in production between partner and non-partner cocoa farmers. It is clear from the research findings above that the company PT TMCI has an influence on the partnership by helping farmers learn more by directing the cocoa growing process. In addition, it can increase output and generate partner income. Keywords: Partnership, Production, Revenue, Impact, Cocoa

Environmental conditions in a large area often requires monitoring. For example, in the case of greenhouse used for experimental research cultivation, fertilization experiment, experiment plant resistance, tissue culture experiments, experimental planting of crops in the off-season, the necessary equipment to monitor and control the environmental conditions in order to suit the characteristics of the environment is needed. The size of area to be monitored, making the need for the spread of monitoring equipment at some point so that monitoring environmental conditions can include all the desired area. This is the basis for the design of communication protocols for WSN (wireless sensor networks) on a green campus. The system consists of hardware that is assembled to the process of measuring PM2.5, CO, NO2, HC, light intensity, temperature, and humidity. The system is divided into several sections, hereinafter referred to node. Node on this system can be divided into two functions, namely a sensor node and coordinator node. There are two sensor nodes that will work for data collection in a separate area and sends the data to the coordinator node. Communication between nodes is done using nRF905 module. The design of communication protocols that are designed to connect between the coordinator node to sensor node is able to run well. It makes the system capable of monitoring temperature and humidity via a web service, so that can know the condition of PM2.5, CO, NO2, HC, the intensity of light, temperature and humidity at some point in the range of more than 100 meters.

Character Education teaches habits of ways of thinking and behavior that help individuals to live and work together as family, community and state and help them to make accountable decisions. This study aims to determine the implementation of character education through school culture in the formation of students' character. The writing method is in the form of qualitative based on previous studies and investigations collecting and analyzing documents, journals and books relating to the discussion about students' character education through school culture. Based on the articles collected, it was found that the implementation of character education through school culture was carried out by habituation that was carried out routinely and consistently in accordance with the school's vision and mission. Character education through school culture requires the efforts and hard work of all parties, both internal and external schools in self-examination and responsible for a change in the character of students now and in the future.

Creative Problem Solving (CPS) is a process to solve a problem faced imaginatively and resulted in effective action. There are 4 aspects that are assessed in CPS which are fact finding, problem finding, idea finding, and solution finding. With the assumption that CPS could be trained and improved, this research aim is to investigate the enhancement of senior high school student's CPS skills after practicing STEM-based learning. The topic in this research is the concept of momentum and impulse using LEGO® Mindstorm EV3 as the media. This study uses a pre-experimental method with one group pretest-posttest design. The sample of this research is 25 senior high school students in Bandung that are determined with the cluster random sampling technique. By analyzing the N-Gain, the result shows that the enhancement of CPS skill is in the middle category with between 0.31-0.63.
