The mining system applied at TB 1.42 Pemali is a mechanical mining system where the mining system activities are conducted by transferring the excavation result of kaksa from work front to stockpile to be wasted using a jig. In terms of mining productivity, the realization of tin ore production was only 80% from the total production that has been planned by the company on November and Desember. Therefore, an evaluation of factors effecting prodution target is essential to do in order to meet unachieved production target. The research was conducted based on the performance coefficient value of load-haluage and transport equipment productivity in November and December assessed from the productivity of the excavators, loaders, and transforting vehicles in March, which is assumed to have the same condition as that in November adn December. An evaluation was conducted to examine the values of mine, effective usage of working time, and the number of bucket loading. The data is then processed using mechanical eatrhmoving formula.The value of performance coefficientin November and December were 0.9 and 0.8, while the performance coefficient of the company are 1.1 – 1.2. After conducting an evaluation, it is found that the factors that lead to failure in achieving the target of production are the long cycle time of the load-haulage equipment, low efficiency of labor, and low match factors. The efforts that should be taken to increase the realization of target achievement are decreasing the cycle time of the load-haulage, increasing the effective usage of working time, and addin in match factor. The cycle time is shortened to 1.159,5 seconds from the initial cycle time of 1.267,8 seconds. The effective usage of working time is increased to 0.75% from 0.727% and the number of load-haulage is increased to 6 from 4 units. After the changes have been done, the production realization in November and December increasing to 156.21 tons of Sn and 128.59 tons of Sn with performance coefficient value of 1.2, thus the production target of the company is achieved.

Nouthetic Counseling for Prison Inmates
Authors: Kim Sang-Hee 
Published: November 2022

Counseling is a field that is rapidly developing as the importance of the individual is recognized by society in the modern era. Counseling is also developing in Christian society, and the spectrum of theories and techniques is very wide depending on the perception of human beings and the perspectives of each party. Among them, there has already been a lot of approbation and criticism for Jay Adams, who opened a new horizon of biblical counseling through nouthetic counseling. However, no one can deny the contribution and influence of his counseling studies. In particular, a bigger effect can be expected for groups in special circumstances. One of those special groups is the prison inmates. They have their own peculiarities such as the isolated environment, psychological and physical stress, and heavy guilt, unlike the other groups of counselees. Indonesia is a country with a large population, but there is still insufficient interest in prison inmates. In addition to this, it is unfortunate that, like in most other countries, there are not many scholars who have studied this field until now. Now in Indonesia, outside volunteers are in charge of many parts of the ministry for inmates counseling and edification of inmates. However, the reality is that these volunteers lack professional counseling education and training. And most Christian volunteers use prayer and the Bible as their primary counseling tools.
